Rising damp occurs when moisture travels upward through the walls of your property due to capillary action. This type of damp can cause serious structural damage, so it’s critical to address it promptly. One effective solution is the installation of a damp proof membrane—a high-density, waterproof barrier that prevents moisture and contaminants from seeping in.

Our experienced team will either install a new damp proof course or repair an existing one to provide long-lasting protection for your property. With our professional treatment, you can trust that your home will remain damp-free for years to come.

Partnering with us means you’ll receive only the necessary services—no unexpected renovations or hidden fees.

Penetrating Damp

What to Know and How We Can Help

If you’re dealing with damp in your property, it often means excess moisture is seeping into your walls, ceilings, or floors, which can lead to significant issues over time.

One common type of penetrating damp is lateral damp. This occurs when groundwater enters your property horizontally through cracks or porous materials in the walls or floors. Lateral damp is particularly common in basements and below-ground spaces, as these areas are more frequently in contact with soil.

Left untreated, lateral damp can lead to structural damage, mould growth, and wood rot. Damp proofing affected walls is essential, as it not only prevents visible damage and structural wear but also helps protect against health concerns such as respiratory issues and improves energy efficiency by reducing moisture retention

About Damp Proof Course (DPC)

A damp proof course (DPC) is a protective barrier that prevents moisture from rising through the walls of a building. DPCs can be made from various materials, including plastic, lead, and rubber, each designed to block moisture effectively.

Most properties built in the last century come with a DPC already installed. However, older buildings may lack this protection, as DPCs weren’t commonly used in construction until more recent times. Even in modern buildings, age or structural movement can weaken a DPC, reducing its effectiveness over time.

Determining if your DPC is compromised can be challenging, as damage isn’t always immediately visible. To ensure your DPC is functioning correctly, it’s essential to consult a trusted London damp proofing company that can survey your property and recommend appropriate treatments. Often, damp becomes evident only after visible damage has occurred, making early detection crucial.
