Professional Damp Proofing

in Muswell Hill

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

Damp Proofing

We offer a variety of damp proofing techniques to our customers in the Muswell Hill area. To decide which is likely to be most effective, we perform full damp surveys to assess the nature and extent of the problem. From here, our damp proofing specialists can devise an appropriate plan to tackle the damp and rot in your property.

Rising Damp

Rising damp is commonly found in older buildings in and around Muswell Hill. Caused by capillary action, ground water is drawn up through porous building materials, where it seeps through the plaster causing damage to the walls. We perform Damp Proof Course (DPC) injections to remedy the situation and prevent the condition from reoccurring. For peace of mind, all rising damp work carried out by Olympic Preservation Ltd is covered by our 20 year guarantee.

Wet Rot and Dry Rot

If our damp surveys bring up evidence of wet rot and dry rot, it is essential that we dispose of them at once. Both of these fungal conditions prove highly damaging to your property, affecting masonry, woodwork, and plaster. We have several treatments available to eradicate the rot and disinfect the area to prevent future growth and all our work is covered by a 10 year guarantee.

Woodworm Treatment

There are several types of wood-boring beetle resident in the UK that fall under the generic term of woodworm. Known to lay their eggs on wooden timber, the resultant larvae burrow deep into the wood, eating up the cellulose and damaging the structural integrity of the timber. We use chemical woodworm treatments to rid your property of these pests and guarantee our work for 10 years.

Structural Water Proofing

If you have earth-retaining walls in your property, such as underground rooms and basement area, then you make require a structural water proofing solution. We will perform a damp survey to determine the most effective method of preventing water ingress. Our team of damp proofing specialists can then apply it, keeping your rooms dry for future use. We offer 10 year guarantees on all structural water proofing work we undertake.
