Professional Damp Proofing

in North London and Hertfordshire

As your local damp proofing specialists, we have much to offer our customers in North London, Hertfordshire, and beyond.

Here is a few of our more popular services…

Damp Proofing

Damp proofing involves treating the walls of your property to prevent water seeping into the building. The most common example of these are a damp proof course injection and a membrane damp proof course. At Olympic Preservation Ltd, we perform detailed damp surveys to identify the cause and nature of your damp problem. Let our damp proofing specialists recommend the best solution for you.

Woodworm Treatment

Our damp surveys also cover structural concerns such as woodworm. This is a catch-all term that describes the larvae of several breeds of wood-boring insects in the UK. Different species require different treatments but, at Olympic Preservation Ltd, we have experience dealing with all of the common varieties. Our methods include chemical washes and injections and, for serious cases, removing and replacing the affected timbers.

Rendering and Plastering

Once your damp problem has been resolved, you can still be left with unpleasant staining and water damage from mould, condensation, and rising damp. At Olympic Preservation Ltd, we can resolve the issue by rendering and plastering both internal and external walls. We ensure your walls are suitably dried out before applying a neat and even finish.

STRUCTURAL WATER PROOFING​

Whilst all water proofing is structural to a certain degree, in the damp proofing trade structural water proofing refers specifically to structures that incorporate earth retaining walls. This includes underground rooms such as basements, cellars, and underground car parks. We provide full structural water proofing for such spaces across Borehamwood, Cricklewood, Finchley, Hendon, North Finchley, and beyond. We offer 10 year guarantees on all structural water proofing work we undertake.

Wet Rot and Dry Rot

Both wet rot and dry rot are picked up on our damp surveys and can be extremely damaging to a property’s structural integrity. Left unchecked, they can eat away at plaster, timber, and even brickwork. Wet rot and dry rot have different effects, but both require immediate removal. We perform fast and effective treatments that eradicate the rot and its subsequent spores as we go and guarantee our work for 10 years.

Rising Damp

Rising damp is caused by capillary action, in which water is drawn up from ground level through porous building materials, including wood and brickwork. Easily recognised by the “tide mark” it leaves on walls, rising damp can cause severe damage to timber, plaster, and more. With the right treatment, we can prevent further occurrences of damp. All rising damp work carried out by Olympic Preservation Ltd is covered by our 20 year guarantee.

Condensation

Condensation is a common problem in many properties across North London and Hertfordshire. The result of a warm, humid environment, it can cause infestations of black mould and fungus on affected walls. We provide a range of solutions, from anti-condensation paints to ventilation systems that eject the warm, moist air from the property.

Damp Surveys

An essential component of any effective damp proofing solution is the damp survey. The damp damage that is visible may only be a part of the overall problem. Our team of damp specialists will perform a thorough investigation of your property, identifying any causes for concern and putting together a suitable solution. Once you are happy with our recommendations, we can start to resolve the problem. Our damp survey specialists can conduct pre-paid damp surveys from £70 to £140.
