Specialist Damp Surveys, Mould Treatment & Timber Preservation Across High Wycombe
Nordic Damp Proofing can inspect your property, explain the problem clearly and recommend appropriate remedial work for your home, rental property or commercial building.
We Find It. We Treat It. We Stop It Coming Back.
Finding damp is relatively easy. Finding out exactly why it is there is the important part.
A damp mark can be caused by rainwater ingress, ground moisture, a plumbing leak, condensation, failed waterproofing, chimney defects, blocked ventilation or moisture trapped behind previous repairs.
Our damp surveys in High Wycombe are designed to separate these causes before treatment is recommended.
Properties across High Wycombe can experience very different moisture problems depending on their age, position, construction and previous alterations.
An older terrace may have low-level damp caused by raised rear ground. A modern flat may have black mould caused by condensation. A house built into a slope may have moisture affecting a lower wall. A property with damaged gutters may show staining only after prolonged rain.
Our complete treatment range can be found on the Nordic Damp Proofing services page.
One feature that can make damp diagnosis particularly important around High Wycombe is the amount of sloping ground.
Properties built into hillsides or with rear gardens higher than the internal floor can experience moisture where water is naturally moving towards the building rather than away from it.
A rear wall may effectively act as a retaining wall where the outside ground is significantly higher than the room inside. In other properties, driveways, patios or garden landscaping may direct rainwater towards external walls.
Problems can include:
Persistent damp on one side of a room
Moisture concentrated along rear walls
Salt deposits close to floor level
Damp becoming worse after heavy rainfall
Water entering through wall and floor junctions
Mould caused by persistently cold damp walls
Damaged plaster at lower-ground level
Timber decay close to affected walls
The solution depends on how the property is constructed and how moisture is reaching the building.
Possible remedial measures can include external drainage improvements, repairs to masonry, internal waterproofing or structural waterproofing where required.
Where external drainage may be contributing to damp, our guide on whether French drains can help stop damp may also be useful.
Damp near skirting boards is often described as rising damp before the property has been properly inspected.
Although rising damp can occur, similar symptoms can be created by several other defects.
In High Wycombe properties, low-level moisture may be caused by:
A bridged damp-proof course
Raised rear gardens
Patios installed too high
Driveways sitting above the correct level
Flower beds against external walls
Leaking water pipes
Blocked airbricks
Poor drainage
Rainwater splashback
Cavity bridging
Moisture beneath floors
Historic salt contamination
Typical warning signs include damaged skirting boards, white salts, peeling paint, plaster breaking away, damp smells and a band of deterioration around the lower section of a wall.
Where rising damp is confirmed, we can recommend the appropriate treatment. This may include damp-proof course installation or damp-proof injection depending on the building.
Our guide on how to fix rising damp explains the issue in more detail.
Condensation forms when moisture in the air meets a sufficiently cold surface. Over time, repeated surface moisture can lead to black mould.
Common locations include:
Bedroom corners
Around windows
Behind wardrobes
Behind beds and sofas
Bathroom ceilings
Kitchen walls
Inside cupboards
External wall corners
Rooms that receive less heating
Modern homes can experience condensation because improved windows and insulation reduce natural air leakage. Older homes can suffer because external walls and chimney breasts remain colder than the rest of the room.
Rental flats can also be affected where several people are generating moisture but ventilation is limited.
Nordic Damp Proofing can investigate the cause and advise on:
Ventilation and condensation surveys
Humidity control and ventilation
Mould removal services
Mould prevention services
Condensation damp control

What is surface moisture?
We Find It. We Treat It. We Stop It Coming Back.
Older properties often contain a mixture of original materials and repairs carried out at different points in the building’s history.
A wall may originally have been designed to manage moisture differently from a modern cavity wall. Later repairs using dense cement, waterproof coatings, modern gypsum plaster or sealed paints can sometimes change how the wall dries.
This may lead to:
Paint repeatedly bubbling
Salts appearing through plaster
Damp moving to a different section of wall
Mould forming on colder surfaces
Old plaster crumbling
Moisture appearing after renovation
Timber near the wall remaining damp
The answer is not automatically to add another waterproof coating.
A survey should establish where moisture is coming from and whether existing materials are contributing to the problem.
