verified by TrustindexTrustindex verifies that the company has a review score above 4.5, based on reviews collected on Checkatrade over the past 12 months, qualifying it to receive the Top Rated Certificate.
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.

A good company to deal with Everyone I dealt with at NDP was charming and pleasant. NDP investigated and addressed a problem with damp in my utility room. As the issue was not run of the mill, NDP sent two people (Daniel & Harvey) to assess the issue before deciding on a treatment programme. Toby & Jack spent two days addressing all possible causes and, at this stage, it seems the works have successfully addressed the problem. I contacted NDP about a couple of things afterwards and Lydia was very helpful and efficient and sent Ryan to assess and address the issues at the earliest opportunity.Posted on Google![]()

Thanks to Ryan who worked internally inside the house on issues that were highlighted in the survey that was completed by Daniel. He got the jobs done efficiently. Also thanks to Jack who worked externally including part of the roof that needed doing before the winter weather hits. Again done efficiently!Posted on Google![]()

Very professional company who were proactive, friendly and very responsive. I felt confident that they would offer a great service, and they did. Toby was very cheerful, knowledgeable and very careful with our property. He cleared up beautifully when he'd finished plastering. Jack was also knowledgeable and suggested alternatives for our guttering, which we were appreciative of. He did an excellent job. The office staff (Lydia) were bright and bubbly and were very responsive, which made the process run smoothly and as painless as possible. I would recommend this company without hesitation as I felt they went the extra mile.Posted on Checkatrade![]()

Nordic - when you want a job well done! From the first telephone conversation, through to the end of the project, the quality and professionalism of the company stood out. Site visits were undertaken before the work began, and after the work was completed, to ensure the highest level of customer service. The team which carried out the work, was courteous, reliable and hard working at all times. The team comprised Blane and his apprentice son Louis. Blane’s skill level is excellent and the finished job demonstrates this. Louis worked hard and is now capable of carrying out most aspects of the work. A job well done. Thank youPosted on Checkatrade![]()

Professional, thorough and very reasonable price - Highly Recommended. Cormac was extremely thorough during his extensive visit to our premises to investigate an ongoing damp issue. Although we generally knew the cause, we needed an independent report to provide to the landlord. Cormac was pleasant and forthcoming in discussion with our Centre Manager on site and understood the requirements. The report we received was detailed and contained extensive photos to evidence his explanations. I cannot recommend Cormac and Nordic Damp Proofing enough! Very professional and thorough, And a small note to say extremely reasonably priced.Posted on Checkatrade![]()

Penetrating Damp & Condensation Treatment We'd tried a few companies to assess our damp and condensation problems but Nordic really stood out. A very thorough survey was carried out by Jason, a few days later a quote was sent and accepted and a very detailed Scope of Work issued. The work was completed quickly and efficiently by Stephen and other Nordic staff, any issues we had were swiftly addressed and professionally handled, our thanks to Jack and Lydia for their constant availability and communication.Posted on Bark![]()

I recently had the pleasure of working with Nordic Preservations to address a damp problem in my bedrooms, and I couldn't be more satisfied with the experience! From start to finish, they delivered top-notch service at a very competitive price. I want to give a special shout-out to Cormac, who was my main point of contact throughout the process. Cormac was incredibly knowledgeable, responsive, and always willing to go the extra mile to ensure everything was done to the highest standard. He took the time to explain the root of the issue and the steps they would take to fix it, which really put my mind at ease. The quality of the work was exceptional, and it's clear that Nordic Preservations takes great pride in their craftsmanship. My bedrooms are now completely damp-free, and the difference is remarkable. I also appreciate how clean and tidy they left everything once the job was done. If you're looking for a reliable, professional, and reasonably priced damp proofing company, I highly recommend Nordic Preservations. Thank you, Cormac, and the entire team for a job well done!Posted on Bark![]()

Brilliant guys, super friendly, very accommodating, brilliant end result
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.
