Cavity Wall Tie Failure | Signs & Replacement Guide

Tue, 06 Oct 2026 13:10:48 GMT

Cavity wall ties are a hidden but important part of many homes across Sunderland, Newcastle and County Durham.

Installed between the inner and outer leaves of a cavity wall, wall ties help hold both sections of masonry together and provide stability to the external wall.

Because they are hidden inside the cavity, problems can develop for many years before homeowners realise anything is wrong.

Older properties in particular can suffer from corroded or deteriorating wall ties, and if the problem is left untreated, it can contribute to cracking, movement and damage to the external brickwork.

Wallseal Preservation provides cavity wall tie inspections and replacement services across Sunderland, Newcastle and County Durham, helping homeowners identify potential problems and determine whether remedial work is required.

What Are Cavity Wall Ties?

A cavity wall is normally constructed using two separate layers of masonry:

An external brick or masonry wall
An internal block or brick wall

Metal wall ties are installed across the cavity to connect the two leaves together.

Their job is to help the wall act as one stable structure while still maintaining the cavity between the inner and outer sections.

Wall ties are generally hidden from view, which means their condition cannot usually be assessed simply by looking at the outside of a property.

Why Do Wall Ties Fail?

One of the most common causes of wall tie failure is corrosion.

Older wall ties may have been manufactured from materials that become vulnerable to corrosion after decades of exposure to moisture within the cavity.

As the metal corrodes, it can expand.

This expansion can place pressure on the surrounding mortar and brickwork, eventually causing visible cracking.

Other potential issues can include:

Poor-quality original wall ties
Inadequate installation
Incorrect spacing
Exposure to moisture
Age-related deterioration
Previous alterations to the property
Structural movement

The exact cause should be established before any remedial treatment is recommended.

What Are the Signs of Wall Tie Failure?

Wall tie problems can produce several warning signs.

These may include:

Horizontal Cracking

One of the better-known signs of wall tie corrosion is horizontal cracking along mortar joints.

This can occur when a corroding metal wall tie expands and places pressure on the surrounding masonry.

Bulging Brickwork

In more advanced cases, sections of an external wall may begin to bulge or move.

Any visible movement within masonry should be investigated.

Cracks Around Windows or Openings

Cracking can sometimes develop around windows, doors and other areas where the masonry is under additional stress.

Loose or Deteriorating Masonry

Areas of brickwork may become unstable or show signs of deterioration.

Problems Identified During a Property Survey

Wall tie defects are sometimes first raised during a structural survey, mortgage valuation or pre-purchase property inspection.

A surveyor may recommend a specialist wall tie inspection before a property transaction proceeds.

Does Horizontal Cracking Always Mean Wall Tie Failure?

No.

Horizontal cracking can have several possible causes, which is why diagnosis is important.

Cracking may also be associated with:

Thermal movement
Settlement
Structural movement
Deteriorating mortar
Previous building alterations
Other masonry defects

A specialist inspection can help establish whether wall ties are contributing to the problem.

How Are Wall Ties Inspected?

The condition of wall ties may be assessed using a combination of visual inspection and specialist surveying techniques.

The survey may consider:

Age and construction of the property
Pattern and location of cracking
Condition of external brickwork
Existing wall tie positions
Signs of corrosion
Movement within the masonry
General condition of the cavity wall

Where appropriate, specialist inspection equipment may be used to investigate the wall cavity.

Wallseal Preservation provides free homeowner surveys for a range of structural and property preservation issues, including cavity wall tie problems. Wallseal Preservation

What Happens If Wall Tie Failure Is Confirmed?

If the existing wall ties have deteriorated, replacement ties can normally be installed into the masonry.

The replacement system is designed to restore the connection between the inner and outer leaves of the cavity wall.

Depending on the property, remedial work may involve:

Locating the existing wall ties.
Installing new remedial wall ties.
Isolating or treating defective existing ties where appropriate.
Repairing damaged mortar joints.
Making good affected masonry.
Addressing any associated cracking or repointing requirements.

Every property should be assessed individually before determining the most appropriate repair method.

Can Wall Tie Failure Cause Structural Problems?

Potentially, yes.

Wall ties play an important role in stabilising cavity walls.

If enough ties deteriorate or fail, the outer leaf of the wall can become less securely connected to the main structure.

That is why suspected wall tie problems should not simply be ignored, particularly where visible cracking or movement is developing.

Early investigation can help identify the extent of the problem before more extensive masonry damage occurs.

Wall Tie Failure and Older North East Properties

Many homes across the North East were constructed during periods when cavity wall construction became increasingly common.

As those properties age, original metal components within the walls can also deteriorate.

This makes wall tie condition particularly relevant when inspecting older properties in areas including:

Sunderland
Newcastle upon Tyne
Washington
Chester-le-Street
Durham
Seaham
Houghton-le-Spring
Gateshead
Surrounding North East communities

The presence of older wall ties does not automatically mean there is a problem, but visible cracking or movement is worth investigating.

Should Wall Ties Be Checked Before Buying a House?

If a building surveyor has raised concerns about cracking, masonry movement or possible wall tie corrosion, a specialist inspection can provide additional information before you commit to the purchase.

This may help establish:

Whether wall tie failure is present
The likely extent of the problem
Whether replacement is required
Whether associated masonry repairs are needed
The likely scope of remedial work

Wallseal Preservation also provides pre-purchase and pre-sale property preservation surveys where damp or structural preservation concerns have been identified.

How Long Does Wall Tie Replacement Last?

A correctly installed modern remedial wall tie system is designed to provide a long-term solution.

Wallseal Preservation provides transferable guarantees on qualifying cavity wall tie replacement work, alongside damp proofing and repointing services. Wallseal Preservation

Do Cracks Need Repointing After Wall Tie Replacement?

This depends on the condition of the masonry.

Where corrosion has damaged mortar joints, repointing may form part of the remedial work.

If cracks are more significant, additional masonry repair techniques may also be recommended.

Wallseal provides both wall tie replacement and repointing services, which allows the condition of the wider wall structure to be considered rather than dealing with each defect separately. Wallseal Preservation

When Should You Arrange a Wall Tie Survey?

It is worth seeking specialist advice if you notice:

Horizontal cracks in mortar joints
Bulging external brickwork
Recurring cracks following previous repairs
Loose or unstable masonry
Cracking around openings
Concerns raised during a building survey
Suspected wall tie corrosion

The earlier the cause is identified, the easier it is to determine the appropriate repair.

Mould Removal Services North East | Wallseal Preservation

Professional Mould Removal, Damp Diagnosis & Mould Prevention

Professional Mould Treatment in Sunderland, Newcastle & County Durham

Mould is more than an unsightly mark on a wall. Persistent mould is usually a sign that excess moisture is present within the property, whether caused by condensation, inadequate ventilation, water penetration or another damp-related problem.

Wallseal Preservation provides professional mould removal and mould control services across the North East , including Sunderland, Newcastle upon Tyne and County Durham.

Rather than simply cleaning the visible mould, our approach is to assess the affected area, investigate the likely source of moisture and recommend the appropriate treatment to help prevent the problem from returning.

PROFESSIONAL MOULD REMOVAL

Don't Just Remove the Mould – Find Out Why It's There

One of the most important parts of treating mould is understanding why it has developed in the first place.

Cleaning or painting over visible mould may temporarily improve the appearance of a wall or ceiling, but if the conditions causing the mould remain, it can return.

Common causes include:

Excess condensation
Poor ventilation
High indoor humidity
Cold walls and surfaces
Penetrating damp
Water leaks or water ingress
Damp within the building fabric
Inadequate heating and airflow

Wallseal Preservation specialises in property preservation, damp proofing, condensation control and mould control. This means we can look beyond the visible mould and help establish what is creating the conditions in which it is growing.

SIGNS OF A MOULD PROBLEM

Do You Have Mould in Your Property?

Mould can occur in both older and modern properties and is particularly common where warm, moisture-laden air meets colder surfaces.

You may need professional advice if you notice:

Black, green or dark patches on walls or ceilings
Mould around windows
Mould behind wardrobes or furniture
Mould in bedrooms
Mould in bathrooms or kitchens
Persistent condensation on windows
Damp or musty smells
Peeling paint or wallpaper
Recurring mould after cleaning
Damp patches alongside mould growth

If you're repeatedly cleaning the same area only for the mould to return, there is likely to be an underlying moisture issue that needs investigating.

OUR MOULD REMOVAL PROCESS

How Does Professional Mould Removal Work?

Every property is different, so the first step should be to establish the extent of the problem and what is causing it.

1. Survey & Assessment

We inspect the affected areas and look for evidence of condensation, damp, moisture ingress and other conditions that could be contributing to mould growth.

2. Identify the Likely Cause

Mould requires moisture to grow. We investigate where that moisture may be coming from rather than treating the visible mould in isolation.

3. Recommend the Correct Treatment

Once the likely cause has been established, we can recommend an appropriate mould control, condensation control or damp treatment solution for the property.

4. Treat the Affected Areas

The mould-affected areas can then be professionally treated using an appropriate method for the surface and extent of the problem.

5. Help Prevent Mould Returning

Where required, we can recommend measures to tackle the conditions behind the mould, including condensation control, improved ventilation or appropriate damp-proofing work.

Survey → Diagnose → Treat → Prevent

BLACK MOULD

Black Mould Removal in Homes

Black mould commonly develops where there is persistent moisture and insufficient airflow. Typical locations include bedrooms, bathrooms, kitchens, window reveals, external walls and areas behind furniture.

Simply wiping black mould from the surface doesn't necessarily resolve the conditions allowing it to grow.

If black mould keeps returning, Wallseal can inspect the property and determine whether condensation, ventilation, penetrating damp or another moisture-related issue could be contributing to the problem.

MOULD AND CONDENSATION

Is Condensation Causing Your Mould?

Condensation is one of the most common reasons for mould growth in residential properties.

Everyday activities such as showering, cooking, drying clothes and even breathing introduce moisture into the air. When warm, humid air comes into contact with a sufficiently cold surface, condensation can form.

Repeated condensation can create ideal conditions for mould.

Typical warning signs include:
Water collecting on windows
Black mould around window frames
Mould in corners of bedrooms
Mould behind furniture
Damp external walls
Persistent high humidity
Mould becoming worse during colder months

Wallseal provides dedicated condensation control services, allowing us to investigate the wider moisture problem rather than simply treating its visible symptoms.

WHY PROFESSIONAL TREATMENT?

Why Choose Professional Mould Removal?

Small areas of surface mould may sometimes appear straightforward to clean, but recurring or widespread mould deserves further investigation.

Aggressively brushing or scrubbing established mould can disturb spores, while decorating directly over mould generally disguises rather than solves the underlying problem.

Professional assessment can help determine:

What is causing the mould?
Is it condensation, ventilation, a leak, penetrating damp or another moisture problem?

How extensive is the problem?
Visible mould may only represent part of the affected area.

What treatment is appropriate?
Different moisture problems require different solutions.

How can it be prevented from returning?
Long-term mould control depends on reducing or eliminating the conditions supporting its growth.

HEALTH & SAFETY

Is Mould Dangerous?

Damp and mould should not be ignored, particularly where mould is extensive, persistent or occurring in frequently occupied rooms.

Exposure to damp and mould can affect indoor air quality and may contribute to respiratory symptoms, allergies and irritation. People with existing respiratory conditions, children, older people and those with weakened immune systems may be particularly susceptible.

If you have significant or recurring mould growth, professional assessment is recommended.

If you are concerned that mould exposure is affecting your health, you should seek appropriate medical advice as well as addressing the condition of the property.

Damp Surveys vs Damp Proofing Companies in Sunderland

Sun, 12 Jul 2026 07:17:34 GMT

Independent Damp Surveys vs Damp Proofing Companies: Which Is Right for Your Home?

If you have discovered mould, peeling wallpaper or damp patches in your property, your first instinct may be to search online for a damp specialist. However, many homeowners across Sunderland, Newcastle and County Durham ask the same question:

Should you pay for an independent damp survey, or contact a damp proofing company directly?

Understanding the difference can help you make an informed decision, avoid unnecessary costs and ensure the correct treatment is recommended for your home.

What Is an Independent Damp Survey?

An independent damp survey is designed to identify the source of moisture problems within a property. A surveyor will inspect your home and assess the condition of the walls, floors and external structure to determine the cause of the issue.

Common causes of damp include:

Rising damp.
Penetrating damp.
Condensation.
Faulty gutters and downpipes.
Poor ventilation.
Damaged brickwork or pointing.
Plumbing leaks.
Structural movement.

An independent survey provides an unbiased assessment and helps homeowners understand exactly what work, if any, is required.

When Should You Contact a Damp Proofing Company?

A reputable damp proofing company not only investigates the issue but can also recommend and carry out the necessary repairs.

Experienced specialists understand the unique challenges faced by homes throughout the North East, from Victorian terraces and coastal properties to modern housing developments.

Professional damp proofing services often include:

Rising damp treatments.
Penetrating damp repairs.
Mould removal and prevention.
Condensation control.
Basement waterproofing.
Cavity wall tie replacement.
Structural repairs and repointing.

Choosing a company with experience in diagnosing the root cause of damp is essential to avoid unnecessary or ineffective treatments.

The Most Common Causes of Damp in North East Homes

Properties across Sunderland, Newcastle and Durham vary significantly in age and construction, meaning damp problems can arise for many different reasons.

Some of the most common causes include:

Blocked or overflowing gutters.
Cracked render and damaged pointing.
Defective windows and doors.
High external ground levels.
Poor airflow and ventilation.
Failed damp-proof courses.
Basement water ingress.
Faulty plumbing.

Many homeowners assume they have rising damp when the real issue is condensation or water penetrating through external defects.

Correct diagnosis is vital before any work begins.

Should You Arrange a Damp Survey Before Buying a House?

One of the most common questions asked by buyers is whether a damp survey should be carried out before purchasing a property.

A professional survey can identify:

Hidden damp problems.
Structural defects.
Mould and condensation issues.
Failing cavity wall ties.
Previous repair work.
Potential future maintenance costs.

For older properties in particular, arranging a damp survey before exchanging contracts can provide peace of mind and prevent expensive surprises later.

Independent Survey or Damp Proofing Contractor: Which Is Better?

There is no single answer, as the right option depends on your circumstances.

An independent survey may be suitable if:

You are buying or selling a property.
You require an unbiased report.
You want a second opinion.
Structural movement is suspected.

A damp proofing company may be the better option if:

Damp or mould is already visible.
Repairs are likely to be needed.
You require practical recommendations.
You want both diagnosis and treatment from the same company.

The most important factor is ensuring that the cause of the damp is properly identified rather than simply treating the symptoms.

How to Prevent Damp Problems in Your Home

Regular maintenance can significantly reduce the likelihood of damp issues developing.

Homeowners should:

Check gutters and downpipes regularly.
Keep air vents clear.
Repair damaged pointing and brickwork.
Fix leaks as soon as they appear.
Improve airflow in kitchens and bathrooms.
Monitor basements and lower-ground rooms.

Addressing small issues early can help prevent more serious and costly problems in the future.

How to Tell the Difference Between Rising Damp, Penetrating Damp & Condensation

Mon, 11 May 2026 11:30:16 GMT

How to Tell the Difference Between Rising Damp, Penetrating Damp & Condensation

Damp is one of the most common problems faced by UK homeowners, yet it is also one of the most misunderstood. Many people notice peeling wallpaper, black mould or damp patches and immediately assume they have rising damp. In reality, the issue could be condensation, penetrating damp, or something entirely different.

Correctly identifying the type of damp affecting your property is essential because each problem requires a different treatment approach. Misdiagnosing damp can lead to unnecessary costs, ineffective repairs and ongoing structural issues.

In this guide, we explain the key differences between rising damp, penetrating damp and condensation, helping you understand what signs to look for and when to seek professional help.

Structural damp occurs when unwanted moisture enters or forms within a building, often leading to mould growth, damage to plaster and timber deterioration if left untreated.

What is Rising Damp?

Rising damp occurs when groundwater travels upwards through brickwork and masonry by capillary action. This usually happens when a damp proof course (DPC) has failed, been damaged or does not exist at all.

Although rising damp is less common than condensation, it can cause serious long-term damage to walls, skirting boards and flooring if ignored.
Common Signs of Rising Damp
Damp patches appearing on the lower sections of walls
Tide marks or staining on plaster
Crumbling skirting boards
Peeling paint or wallpaper
White salt deposits on walls
A musty smell
Cold, damp walls to the touch

Rising damp is usually limited to the lower metre of a wall because moisture rises from ground level.

Common Causes of Rising Damp

Failed damp proof course
Bridged DPC caused by raised external ground levels
Older properties with no original DPC
Damaged brickwork or mortar joints

Professional damp surveys are often required to properly diagnose rising damp because it is frequently confused with condensation.

What is Penetrating Damp?

Penetrating damp occurs when water enters the building from outside. Unlike rising damp, it can appear anywhere on walls or ceilings depending on where the water ingress occurs.

This type of damp is usually linked to defects in the building’s exterior.

Common Signs of Penetrating Damp
Damp patches on walls or ceilings
Wet walls after rainfall
Bubbling plaster or paint
Mould growth in isolated areas
Water staining around chimneys or windows
External brickwork deterioration

Penetrating damp often worsens during periods of heavy rain, making seasonal changes an important clue when diagnosing the issue.

Common Causes of Penetrating Damp

Leaking gutters or downpipes
Cracked render or damaged brickwork
Faulty roofing or flashing
Cavity wall issues
Poorly sealed windows and doors

Unlike condensation, penetrating damp is usually localised to one area rather than spread throughout the property.

What is Condensation?

Condensation is the most common form of damp found in UK homes. It occurs when warm, moisture-filled air comes into contact with colder surfaces, causing water droplets to form.

Modern lifestyles often increase indoor moisture levels through cooking, showering, drying clothes indoors and poor ventilation.

Common Signs of Condensation

Water droplets on windows
Black mould around window frames
Mould behind furniture
Damp patches in corners of rooms
Excess humidity indoors
Musty odours

Condensation is most commonly found in kitchens, bathrooms and bedrooms where moisture levels are highest.

Common Causes of Condensation

Poor ventilation
Inadequate heating
Drying clothes indoors
Blocked air bricks or extractor fans
Poor insulation

Condensation can often be improved with better airflow, extractor fans, positive input ventilation systems and consistent heating.

Why Correct Damp Diagnosis Matters

One of the biggest mistakes homeowners make is treating the symptom instead of the cause. Simply repainting over mould or using anti-mould sprays may temporarily improve appearance, but it will not solve the underlying issue.

For example:

Installing a new damp proof course will not fix condensation.
Improving ventilation will not stop penetrating damp caused by leaking gutters.
Replastering walls without addressing rising damp will only lead to recurring damage.
Professional damp specialists use moisture readings, visual inspections and building analysis to determine the true source of the problem before recommending treatment.

How Damp Can Affect Your Property

Leaving damp untreated can result in:

Structural timber decay
Rotting skirting boards and flooring
Damaged plaster and decorations
Increased heating costs
Reduced property value
Mould growth affecting indoor air quality
Damp and mould can also negatively impact respiratory health, especially for children, elderly occupants and those with asthma or allergies.

When Should You Call a Damp Specialist?

You should seek professional advice if you notice:

Persistent mould growth
Recurring damp patches
Peeling wallpaper or bubbling paint
Damp smells that do not disappear
Water ingress after rainfall
Signs of damage to plaster or timber

A professional survey can identify the exact cause of damp and help prevent unnecessary repair costs later. Get in touch

The Hidden Dangers of Mould: A Threat to 1 in 5 UK Homes and Respiratory Health

Thu, 29 Jun 2023 15:43:36 GMT

Unveiling the Hidden Threat: Mould's Impact on Respiratory Health in the UK

In the tranquil corners of our homes, lurking in the shadows, there exists a silent menace that can wreak havoc on our health and well-being: mold. Unbeknownst to many, mould is a common problem in households across the United Kingdom, affecting approximately one in every five homes. Besides its unsightly appearance and pungent odor, mould poses serious risks to respiratory health. In this blog post, we will explore the dangers of mould, its prevalence in UK homes, and its impact on our respiratory system.

Understanding Mold

Mould is a type of fungus that thrives in damp and humid environments, making our homes an ideal breeding ground. It reproduces by releasing spores into the air, which can settle on various surfaces and grow into colonies. These colonies can appear as discolored patches, often black, green, or brown, and give off a musty odor.

Prevalence in UK Homes

Recent studies have revealed the alarming truth that mold affects approximately one in five homes in the UK. Factors such as poor ventilation, water leaks, condensation, and high humidity levels contribute to the growth of mould. Older properties with inadequate insulation and insufficient maintenance are particularly vulnerable. Additionally, changes in weather patterns, leading to increased rainfall and flooding, have exacerbated the issue.

Respiratory Health Risks

The presence of mold in our homes poses significant risks to our respiratory health, particularly for individuals with allergies, asthma, or weakened immune systems. Mould spores can be inhaled and cause a range of health problems:

Allergic Reactions: Mould spores act as allergens, triggering allergic reactions in sensitive individuals. Symptoms may include sneezing, coughing, itchy or watery eyes, and skin rashes. Prolonged exposure to mould can lead to chronic allergic conditions, such as allergic rhinitis or bronchial asthma.

Asthma Aggravation: For people already living with asthma, mould can worsen their symptoms and increase the frequency and severity of asthma attacks. The presence of mold in the environment can trigger wheezing, chest tightness, shortness of breath, and persistent coughing.

Respiratory Infections: Mould can also cause respiratory infections, especially in individuals with weakened immune systems. Aspergillus, a common type of mold, can lead to fungal lung infections that may cause coughing, fever, chest pain, and fatigue.

Toxic Effects: Certain moulds, such as Stachybotrys chartarum (commonly known as black mold), produce mycotoxins that can have toxic effects on the respiratory system. Inhalation of these mycotoxins can lead to severe respiratory symptoms, including chronic cough, nosebleeds, headaches, and fatigue.

Prevention and Remediation

Given the potential risks mold poses to our health, it is crucial to take preventive measures and address mould problems promptly. Here are some tips to minimize mould growth:

Maintain Proper Ventilation:

Ensure good air circulation by using extractor fans in bathrooms and kitchens, and keep windows open when possible to reduce humidity levels.

Fix Leaks and Dampness: Repair any water leaks, damp walls, or roofs promptly. Mould thrives in moist environments, so it is essential to address the underlying causes.

Control Humidity: Use dehumidifiers in areas prone to dampness, such as basements and laundry rooms, to keep humidity levels below 50%. Avoid drying clothes indoors as it increases moisture in the air.

Proper Insulation: Ensure your home is adequately insulated to prevent condensation and reduce the likelihood of mould growth.

Building Repairs And Maintenance

Why do I need repairs and maintenance?

Repairs and maintenance are a necessary aspect of looking after a building. Most structures will eventually develop some kind of flaw over time, for an assortment of reasons. Subsidence, pollution, age, and previous substandard building work can all contribute to the need for repair.

It is imperative to deal with any problems as soon as they are detected, as the longer such defects are left without attention the harder it gets to fix them, and the worse the consequences can get. If neglected long enough, structural defects can lead to displaced walls, issues with the foundation, or even partial collapse of the building, which is obviously extremely unsafe. Additionally, if you are considering selling your property in the future, proper maintenance ensures the building retains the best possible value.

What should I look for?

You may need to consider repairs and maintenance for your building if you notice:

Damp areas.
The presence of mould.
Cracks appearing on either the interior or exterior of the building.
Excessive weathering or other deterioration on outer walls.
Leaks and drips.
Dry or crumbling timber.

What is basement waterproofing?

What is basement waterproofing?

Basements are more susceptible to damp problems than other areas of a building, due to their lower position. If you are considering making your basement liveable or embarking on a conversion project, a solid basement waterproofing system is one of the first things to take into account. A usable basement can make an excellent addition to a house, and often improve the value of the property, but without sufficient waterproofing such a project is unworkable.

Why do I need basement waterproofing?

Basements often sit below the water table, which means that they are likely to be affected by ground water exerting pressure on the walls. Inadequate protection against this can lead to various issues with damp, rot, and general deterioration of the walls and floor. In severe cases the basement may be rendered completely uninhabitable or unusable, and could cause other structural problems in the rest of the building.

What should I do next?

There are a few different kinds of waterproofing systems that can be implemented. Methods involving tanking and and external waterproofing used to be very common, but barriers put into place on the exterior walls of a basement can deteriorate fairly quickly. Newer basement waterproofing methods are based on the concept of safely managing the water that does get through.

Penetrating Damp Treatments In Sunderland

What is penetrating damp?

Penetrating damp is quite simply moisture that passes through the roof or walls of a building from an outside source, and is often associated with defects in construction or plumbing.

What causes penetrating damp?

Generally, it is caused by water escaping from broken or damaged pipes or plumbing. Causes to look for might be cracked or obstructed gutters and overflow pipes, insufficient waterproofing, flawed pointing or brickwork, or defective windows and doors. When the moisture penetrates the structure, it can start to affect timber and damage any paintwork or plaster it reaches.

What should I look for?

If you spot any of the following signs, your building may have penetrating damp:

Patches of black mould.
Plaster and paint that appears stained and damaged, or has ‘tidemarks’.
Damp spots on the wall that do not fade or dry.
An odour of mustiness.
Wood that seems damaged or decayed.
Growth of moss or other plants on exterior brickwork.

What should I do next?

It is imperative that the source of the dampness be isolated and fixed. If no attempt to remedy it is made, penetrating damp can leave the building vulnerable to other damp-related issues such as wet rot, dry rot, and insect infestation, or cause damage to interior décor that is costly and time-consuming to repair and replace.
