Damp Proofing

Damp in the home could be defined as unwanted moisture. In sufficient quantities it causes a host of damp problems ranging from the aesthetic including mould formation, spoiling of paint and plasterwork, through to more serious structural issues including wet rot and dry rot.

No matter what type of damp you have, you should contact Prokil for a survey. Our fully trained surveyors will provide you with effective solutions which can be swiftly implemented by our experienced workforce. Leaving you free to enjoy your damp-free home.

What causes damp

Damp is typically caused by a myriad of factors such as poor property maintenance, defective rainwater goods, shoddy building work using poor building materials, leaking roofs, and the absence or failure of a damp proof course (DPC). Essentially, anything that causes water to come into contact with a property can mean that before long damp will become a problem.

We will conduct a thorough survey of your property and provide you with a report of our findings and recommendations.

The three most common kinds of damp to affect homes are rising damp, penetrating damp and condensation:

Penetrating damp

Penetrating damp is caused by water leaking directly through the walls. This type of damp may move around a building laterally or from above. Penetrating damp is usually caused by structural problems or defects in a building. The most common causes are leaking gutters and downpipes, porous brickwork, defective pointing, inadequate drip grooves, and defective joints and seals around the doors and windows.

It can also be caused by the ground level outside your home being higher than the floor level and damp proof course. Watermarks will worsen if water continues to enter which will lead to the following: damaged interior plasterwork, persistent random damp patches, mould growth forming on walls, musty smells, and damaged timber which can lead to wet or dry rot.

Rising damp

Rising damp can occur when your Damp Proof Course (DPC) is missing, damaged or bridged. Ground water rises up through the masonry, usually through porous mortar joints and can travel up to a metre up your walls. Visible signs include a tide mark on walls, white marks or discolouration caused by mineral salts carried up from the ground.

Resolving rising damp

At Prokil, we recommend a two-part process to remedy rising damp. A hand injected chemical DPC controls the damp and the re-plastering prevents future spoiling of interior decoration. It is essential that both processes are carried out to achieve a consistently damp-free property.
