About Penetrating Damp

What is Penetrating Damp?

Penetrating damp is caused by water infiltrating a building or property through the external wall, defective pointing, roof, cracks or underground area of a building. Though it is commonly noticed in older buildings, it can also affect modern buildings with poor drainage system or defective masonry. It occurs when there is a defect in the building like a leaking roof, leaking water pipe, poorly constructed gutter channels, holes in the chimney and also when the external walls of a property have degraded thereby allowing water to penetrate from the wall into the building. Penetrating damp is also common in poor cavity wall construction where cavity wall insulation has been poorly installed or walls that are not suitable for cavity wall insulation are used in the installation process. Penetrating damp is more common if you live in an area that experiences heavy rainfall.

Common signs of penetrating damp :

1

Watermarks

Watermarks on walls, ceilings, cabinets, and carpets indicate the presence of penetrating damp. If the stain has dark spots, the damage is recent. However, if the stain is brown or chalky, it indicates older damage typically caused by excess moisture.

2

Blistering Plaster

When the inside of a wall becomes wet and expands, it is often accompanied by blistering plaster, peeling paint, or wallpaper. This indicates a problem that should be addressed as soon as possible.

3

Presence of mould

Mould cannot grow without moisture. As long as areas in your home remain wet, mold will inevitably develop. This issue is commonly observed in areas affected by penetrating damp.

4

Damaged interior

If your interior wall decorations become damp and show water stains, it indicates that you have a problem with penetrating damp.

5

Damp or Musty odour

Damp or musty odour is another of the sign of Penetrating damp on interior walls. 

6

Rotting floor timbers

If your floor timber is wet and rotting away, it could be a sign of penetrating damp.

Penetrating Damp Treatment process

Penetrating damp solutions

 

At Advanced Damp Ltd, we provide a thorough and effective approach to treating penetrating damp. Our process includes the following steps:

1. Detailed Survey and Diagnosis

We begin with a comprehensive survey of your property to identify the source of the penetrating damp. Our experts inspect all potential points of water ingress, such as cracks in the walls, missing roof tiles, and blocked gutters. This detailed diagnosis allows us to develop a tailored treatment plan.

2. Remedial Work

Once we determine the cause, we start the remedial work to fix the problem and protect your property from further damage. Our solutions include:

  • Installation of PIV Units: For severe cases, we may install Positive Input Ventilation (PIV) units to push out moist, stale air and keep your walls and windows dry.
  • Vapour Retarders: If the brickwork or stonework has become porous due to water buildup, we apply specialised vapour retarders to reduce moisture diffusion through walls, floors, and ceilings.
  • Specialised Drying Equipment: We use advanced drying equipment to treat the affected areas efficiently.

3. Plasterwork and Surface Repair

If the penetrating damp has affected your plasterwork, we completely remove the damaged plaster and replace it with damp-resistant plaster to ensure long-lasting results.

4. Brick and Stone Treatment

For defective brick or stonework, we provide solutions such as:

  • Brick Replacement: Replacing damaged bricks to restore the structural integrity.
  • Silicone Water-Repellent Fluid: Applying a protective layer to seal the bricks from further water damage.

5. Timber Treatment

If the damp has affected wooden structures, such as timbers, we:

  • Treat and Protect: Address dry or wet rot in the timbers to prevent further decay.
  • Replace: Replace severely damaged timbers.
  • Damp Proof Course Installation: Install a damp proof course to provide additional protection.

6. Mould Remediation

Finally, if mould is present, we conduct thorough remediation to remove contaminated materials and clean the affected areas, ensuring a healthy living environment.

FAQs

If you're dealing with penetrating damp in your home, you probably have a lot of questions. Our FAQs page is here to help! We've gathered some of the most common questions about penetrating damp and provided straightforward answers to help you understand the causes, effects, and solutions for this frustrating problem. Whether you're a homeowner, a landlord, or a tenant, our FAQs page can help you get the information you need to deal with penetrating damp effectively.

Penetrating damp is a type of dampness that occurs when water penetrates through the external walls of a building and makes its way into the internal spaces. It is often caused by defects or damage to the external walls of a building, such as cracks in the brickwork, faulty pointing, or damaged roofing or guttering.

Penetrating damp is caused by water entering a building from the outside. This can happen when there are defects or damage to the external walls, such as cracks in the brickwork, faulty pointing, or damaged roofing or guttering. It can also occur when water is allowed to accumulate around the base of the building, leading to rising damp.

Signs of penetrating damp include damp patches on walls, peeling wallpaper or paint, musty odours, and visible mould growth. These signs can be present on both external and internal walls of the building.

To prevent penetrating damp, it is important to maintain the external walls of your building. This may involve repairing any cracks or damage to the brickwork, ensuring that your guttering is in good condition, and fixing any issues with your roofing. It is also important to ensure that the ground around the building slopes away from the walls to prevent water from accumulating.

The treatment for penetrating damp will depend on the severity of the issue. In some cases, simply repairing the external walls or fixing a faulty gutter may be enough to resolve the problem. In more severe cases, you may need to use a specialist damp-proofing treatment or re-plaster the affected areas. It is important to seek professional advice if you suspect that you have penetrating damp.
