Penetrating Damp Treatment Services

Trusted Penetrating Damp Specialists in London

Your property’s exterior is designed to protect your home from damp infiltration, yet sometimes moisture finds a way in, leading to penetrating damp issues. This type of damp can seep in through various areas, including the roof, walls, pointing, and even below-ground areas. If you’ve noticed damp patches, watermarks, mould growth, or musty smells in your home, it could be a sign of penetrating damp.

At Damp and Mould Solutions Ltd, we provide specialised solutions for identifying and treating penetrating damp, ensuring your home remains dry and protected. Contact us today for a property survey or expert advice on treating penetrating damp.


What Causes Penetrating Damp?

Penetrating damp occurs when moisture enters your property through defects in its external structure. This could include:

  • Defective Masonry or Render: Porous bricks and damaged render allow water to soak through the walls.
  • Roof or Gutter Damage: Leaks from cracked gutters, broken downpipes, or damaged roofs can lead to moisture seepage.
  • Poor Window or Door Pointing: Inadequate sealing around windows and doors lets rainwater penetrate the walls.
  • Cavity Wall Insulation Issues: If the cavity insulation absorbs moisture due to wear or exterior damage, dampness can reach interior walls.

Most penetrating damp issues are the result of wear and tear, cracks, or structural defects. If you notice damp patches around the gutter line, it’s essential to check your gutters and downpipes for leaks.

Accurate Diagnosis is Key
Misdiagnosing a damp issue can lead to ineffective treatment and higher repair costs. With Damp and Mould Solutions Ltd, you’ll receive an accurate assessment and tailored treatment to eliminate penetrating damp the first time.


Treating Penetrating Damp Problems

We start by conducting a detailed survey of your property to determine the source of the problem. Our experienced surveyors can then recommend and apply the right solution to stop moisture from entering your home.

Home Treatments Techniques

  • Use a Positive Input Ventilation (PIV) system: Install a PIV system in the loft to remove moisture and humid air from your home.
  • Use a dehumidifier: A dehumidifier speeds up moisture evaporation, especially in rooms without windows.
  • Improve air circulation: Open windows and use fans to help moisture evaporate faster.

Effective Treatment Techniques

Once we’ve identified the source of penetrating damp, we use traditional building techniques combined with advanced damp proofing methods, including:

  • Physical Membranes and Chemical Water Repellents: We apply a protective barrier to stop water from seeping into your home’s walls.
  • External Waterproofing Systems: In cases of persistent damp issues, we may recommend waterproofing the external surfaces of your home.
  • Repairing Structural Defects: Fixing damaged masonry, roof elements, and guttering to prevent water infiltration.

Whether your home is newly built or decades old, it is vulnerable to damp issues. Treating penetrating damp on your own may not be effective, as it’s easy to misdiagnose the type of damp. Our professional surveyors will inspect your property, identify the cause of the problem, and suggest the appropriate treatment to eliminate penetrating damp.
