Specialist Damp Surveys, Mould Treatment & Timber Preservation Across Oxfordshire

The most effective damp treatment starts with identifying the actual moisture source.
Visible damage can be misleading. A damp patch near a floor may suggest rising damp, but it could equally be linked to an external ground level, leaking pipe, blocked airbrick or moisture entering through the wall. Mould in a bedroom may be condensation, but it can also be made worse by a cold or damp external wall.
Our damp surveys across Oxfordshire assess the wider building rather than just the visible patch.
Where the source needs more detailed investigation, we can also provide survey and diagnostic services.
We Find It. We Treat It. We Stop It Coming Back.
Oxford and other larger towns across the county contain many flats, converted houses and rental properties.
These buildings can experience a different set of moisture problems from detached homes.
In a flat, bathrooms and kitchens may have limited external walls, bedrooms may rely on mechanical ventilation and furniture is often placed close to colder walls.
Converted properties can also have ventilation routes that were changed during subdivision.
Common issues include:
Condensation on windows
Mould behind beds and wardrobes
Bathroom ceiling mould
Cold wall corners
Musty cupboards
Black mould in bedrooms
Moisture around window reveals
Recurring mould after cleaning
It is important to work out whether the problem is primarily condensation or whether a building defect is contributing to colder, wetter walls.
Our ventilation and condensation surveys can help identify the cause.
You can also read our guide on why flats can experience worse condensation than houses.






Condensation forms when humid air meets a colder surface.
Bathrooms, kitchens, laundry, drying clothes indoors and normal daily living all add moisture to the air. If that moisture cannot escape effectively, it can settle on colder walls, ceilings and windows.
Repeated condensation can lead to mould growth.
Nordic Damp Proofing can help with:
Condensation damp control

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
Some Oxfordshire properties sit close to rivers, streams, low-lying ground or areas where external drainage needs particular consideration.
Being close to water does not automatically mean a building will have damp, but drainage, ground levels and below-ground construction may become more important factors when investigating moisture.
Damp that becomes more noticeable during or after wet weather often points towards external water ingress.
Water can enter through a small defect and travel through the wall before becoming visible inside.
Possible causes include:
Internal signs may include irregular stains, bubbling paint, damaged wallpaper, blown plaster and moisture around ceilings or window reveals.
Nordic Damp Proofing provides penetrating damp treatment and can also advise on repointing services where masonry joints are allowing water to enter.
Once the source has been corrected, wall repair and replastering may be needed to restore damaged finishes.
Protect your home before the problem gets worse. Our friendly surveyors will diagnose the issue, explain the results, and recommend the most effective treatment.
At Nordic Damp Proofing, we’re pleased to offer damp, mould, and timber surveys to homeowners and landlords. In some cases, fees may apply for more detailed reports — but don’t worry, our team will always let you know beforehand.
Submitting this form doesn’t commit you to a survey. One of our friendly team members will contact you within 24 hours to discuss your enquiry and confirm whether a survey is needed. Once booked, we can usually arrange a visit within 24 hours of confirmation.
