Professional Damp Proofing

in Potters Bar

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

Damp Proofing

The most common method of Damp proofing to protect your property from water ingress is a damp proof course injection and a damp proof membrane. We undertake an initial damp survey to start with to determine the best solution for your property before inserting a waterproof barrier above the water table to prevent penetrating damp through the walls or floor.

Rising Damp

Rising damp is usually only found on the lower floors of a building caused by moisture being drawn up from the soil through porous brickwork and timbers. By the application of a damp proof course injection directly into the brickwork, it is normally easy enough to remedy – a process here at Olympic Preservation Ltd that we have conducted hundreds of times in properties and buildings throughout the Potters Bar, North London and wider Hertfordshire area.

Wet Rot and Dry Rot

With our thorough and professional surveys, we can also pick up the presence of wet rot and dry rot which is caused by a variety of fungus that thrive in damp conditions causing serious damage to woodwork and masonry alike. It is a two-stage job to remove the rot. We deal with the cause of the damp initially, then carry out the process to eradicate the rot itself, repairing or replacing any damage.  We guarantee any work we undertake for 10 years.

Woodworm Treatment

Woodworm refers to several species of wood-boring beetles that can cause significant damage to your floorboards and timbers if left unchecked and not dealt with promptly. Olympic Preservation Ltd use effective chemical timber treatments throughout properties and buildings in Potters Bar to eradicate all such insects, repairing or replacing any timbers that have suffered extensive damage, all covered by our 10-year guarantee.

Structural Water Proofing

Olympic Preservation Ltd undertake structural water proofing to underground areas that have earth retaining walls such as basements, cellars, and tunnels that allow water ingress because of penetrating damp. Our structural water proofing experts can offer several possible solutions to rectify this issue and will recommend the most suitable one for your property based on our initial damp survey findings. All structural water proofing work we undertake is backed by our 10-year guarantee.

Damp Contractors in Potters Bar

We are professional damp contractors that help on an ongoing basis to the construction industry, Landlords, developers, and property management firms for both domestic and commercial properties and more. Whether you need us to perform regular checks on your existing portfolio of properties or install damp-proof courses on a new-build project, we have decades of experience and are here to help.


If your Potters Bar property is susceptible to condensation, there are several ways in which the professionals at Olympic Preservation Ltd can help.  We will undertake a thorough damp survey before any work can begin. Our expert team will implement the most suitable options which may include anti-condensation paints, unblocking air vents and installing new and efficient ventilation systems such as a PIV (Positive Input Ventilation). A PIV forces out humid air in favour of clean, filtered air which reduces the risk of condensation.

Damp Surveys

Here at Olympic Preservation Ltd, before we start any treatment, we always recommend a full damp survey to establish the presence of rising damp, penetrating damp, condensation, or rot. A full damp survey enables us to plan the best steps we need to take to damp-proof your property. Our damp survey specialists can conduct pre-paid damp surveys from £70 to £140.

Rendering and Plastering

Depending on the work undertaken to resolve your damp issue, your interior and exterior walls may require some remedial action afterwards. Olympic Preservation Ltd will carefully remove any damage from the affected area before replacing it using quality plaster and render to leave your walls with a smooth and flawless finish, ready to be painted or papered.
