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![]()

A damp survey helps identify the real cause of moisture before any treatment is recommended.
In Ascot properties, damp can be linked to poor ventilation, older construction, failed pointing, cracked render, blocked gutters, leaking downpipes, roof defects, chimney problems, raised external ground levels, drainage issues, failed damp-proof courses or timber affected by long-term moisture.
Damp symptoms can look similar even when the cause is different. Mould around windows may be condensation, but it can also be made worse by cold damp walls. Low-level staining may suggest rising damp, but it could be linked to raised ground, leaks, poor drainage or external water ingress.
Our surveyors assess the whole property, including internal symptoms, external walls, ground levels, ventilation, moisture patterns, rainwater goods and signs of timber decay.
Where the issue is more complex, we may recommend our survey and diagnostic services.






Damp at the base of internal walls is often assumed to be rising damp, but it should always be diagnosed before treatment is chosen.
In Ascot homes, low-level damp may be caused by a failed, missing or bridged damp-proof course. It can also be linked to raised patios, flower beds, external paving, poor drainage, leaking pipes, blocked airbricks, condensation at low level or rainwater entering through external wall defects.
Possible signs include damp marks near skirting boards, white salt deposits, peeling paint, crumbling plaster, soft timber, damaged skirting boards, musty smells and staining on ground floor walls.
Where rising damp is confirmed, we can advise on suitable rising damp treatment. This may include damp-proof course installation or damp-proof injection where appropriate.
You can also read our guide on how to fix rising damp.
Black mould is often caused by moisture in the air settling on colder surfaces. It commonly appears in bathrooms, bedrooms, kitchens, window reveals, wardrobes, ceiling corners, cupboards and behind large furniture.
In Ascot homes and apartments, condensation can become worse where properties are well sealed, extractor fans are weak, rooms are not ventilated properly or furniture sits too close to external walls. Larger homes can also suffer from mould in less-used rooms where heating and airflow are inconsistent.
Everyday moisture from cooking, showering, drying clothes indoors and keeping windows closed can quickly raise humidity levels. Cleaning mould from the surface may improve the appearance temporarily, but it will often return if airflow and moisture levels are not corrected.
Nordic Damp Proofing can advise on mould removal services, mould prevention services, condensation damp control and humidity control and ventilation.
You may also find our guides on how to stop mould in your home, why flats can get worse condensation than houses and managing condensation in the home useful.
