Professional Damp Proofing

in Barnet

As your local damp proofing specialists, we have much to offer our Barnet customers. Here is a few of our more popular services…

Damp Proofing

Whether our damp surveys identify your problem as rising damp, penetrating damp, or any other form of surface moisture, we have the tools and experience to help. We have been fitting damp proof membranes and damp proof courses for many years, both of which are proven to combat damp and prevent further damage.

Rising Damp

Our damp surveys most often discover rising damp in older buildings across Barnet. Caused by capillary action, whereby ground water is drawn up through the brickwork and timbers rising damp can cause significant damage over time. Fortunately, it is easily remedied with the appropriate treatment. We cover any rising damp work carried out by Olympic Preservation Ltd for 20 years.

Wet Rot and Dry Rot

Both wet rot and dry rot show up in our damp surveys and need to be dealt with immediately. Not only are they destructive in their own right but, left untreated, they release spores that result in an even greater infestation. We provide an effective wet rot and dry rot removal service for all of our Barnet customers and guarantee this for 10 years.

Woodworm Treatment

As well as damp and rot, our damp surveys also identify infestations of woodworm. This refers to a variety of wood-boring beetles common to the UK. They make holes in your timber, into which they lay their eggs. Once hatched, the larvae chew through the wood (specifically, the connecting cellulose), weakening the timbers. Fortunately, we have a range of chemical solutions to combat such infestations and any work carried out is covered by our 10 year guarantee.

Structural Water Proofing

Structural water proofing is used in underground area such as garages, cellars, or basements, as well as other rooms that have earth-retaining walls. Our damp surveys can normally show us the best way to deal with these conditions. This may involve barrier paints to prevent water ingress, or a dehumidifier and drainage system to dispose of it. Any work we undertake is covered by our 10 year guarantee.

Rendering and Plastering

Once we have treated the damp, all that remains is repairing the damage it has done – most often to your plastering and rendering. Easily damaged by damp conditions, affected plaster becomes very crumbly once it has dried out. We remove any damaged material, replacing it with a fresh batch, mixed on-site to ensure the right consistency and finish.


Condensation is caused by hot, humid air coming into contact with colder surfaces such as walls and windows. It leaves moisture on those surfaces that cause damp conditions in a home or commercial building. We can combat this phenomenon by applying specialist condensation control paint, or by improving the ventilation in the property.

Damp Surveys

We conduct in-depth damp surveys for domestic and commercial customers alike, throughout Barnet. These surveys are essential for correctly assessing the extent of damage that has been caused to a property by damp. They involve a thorough inspection of the building, identifying evidence of damp, dry and wet rot, condensation, and more. We use the resulting report to put together an effective damp treatment plan.  Damp surveys carried out by our damp survey specialists start from £70 to £140.
