Rising damp spreads fast and often without warning, causing severe problems to your property. It has also been linked to various health problems. Fortunately, there are a series of solutions that help fight and prevent rising damp.


Damp Wall


Rising damp occurs when the buildings damp proof course (a waterproof layer built into the brickwork just above ground level) fails, or when the ground level rises above the damp proof course for instance if the soil is piled against an exterior wall. Rising Damp occurs when water absorbed from the ground rises up through the bricks and mortar of the walls of a building by capillary action. The walls soak up the surrounding groundwater like a sponge.


Rising damp can be identified by a tide mark on the bottom of the walls just above the skirting boards, deposits of mineral salts on the walls, bubbling and/or flaking paint and render, and damp, curling wallpaper.

Rising Damp Treatment

The problem could be as simple as a breach in the damp proof course caused by a blocked cavity wall, or as serious as having to install a new damp proof course. This is not as drastic as it sounds, because we can usually inject a chemical damp proof course through drilled holes.

    How much does rising damp treatment cost?

    It depends on the size of your house and the extent of the damage. You need to consider labour cost, the cost of damp proofing used, as well as any repair work such as damp proof paint application. An average damp proof course costs £280 up to £2,000. Waterproof membrane systems are approximately £35 per square metre. Injecting a damp proof course depends on the type of wall and the thickness, but they can cost around £15- £25 a linear metre.

    What's the difference between penetrating damp and rising damp?

    A common difference between penetrative and rising damp is the height at which it occurs where was penetrative damp often occurs anywhere and at any height, while rising damp has a strong tendency to merely occur up to a meter from the ground.

    How do you treat penetrating damp?

    Penetrating damp is treated vis purposeful drilling into the affected area and injecting a damp proofing course layer that stops the ingress of moisture as necessary. Additionally, the brickwork has a waterproof coating applied to stop any further moisture from entering from the exterior surface of the affected wall.
