Homes around Fortuneswell, Chiswell, Easton, Southwell, Weston, Castletown and The Grove may be more exposed to weather conditions, while older buildings may have solid walls, ageing stonework, worn pointing or ventilation issues that allow moisture to build up.

Choosing a specialist damp company gives you reassurance that the cause of the problem will be properly diagnosed before treatment begins.
Our team is trained to identify the difference between rising damp, penetrating damp, condensation, mould growth, timber decay and water ingress. This helps avoid unnecessary work and ensures the correct solution is recommended for your property.

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
Choosing a specialist damp company gives you reassurance that the cause of the problem will be properly diagnosed before treatment begins.
Our team is trained to identify the difference between rising damp, penetrating damp, condensation, mould growth, timber decay and water ingress. This helps avoid unnecessary work and ensures the correct solution is recommended for your property.
Yes. We carry out professional damp surveys throughout Portland for homeowners, landlords, letting agents and commercial property owners. Our surveyors identify the source of the moisture problem and provide clear recommendations for treatment where required.
The first step is identifying what is causing the mould. In Portland, mould is often linked to condensation, poor ventilation, penetrating damp or excess humidity caused by the coastal environment. Simply cleaning mould away will not solve the problem if the moisture source remains. We can inspect the property and recommend the most effective solution.
Mould returns when the underlying moisture problem has not been addressed. This may be caused by condensation, leaking pipework, damp walls, poor ventilation or water ingress. Treating the source of the moisture is essential to prevent recurring mould growth.
Yes. Portland’s exposed coastal location means many properties experience higher levels of humidity, wind-driven rain and salt-laden air. These conditions can contribute to condensation, penetrating damp and moisture-related issues if buildings are not properly maintained and ventilated.
Absolutely. We regularly work with landlords, tenants, property managers and owners of holiday accommodation across Portland. We provide damp surveys, mould investigations and effective treatment solutions for all types of residential properties.
Common signs include black mould growth, musty smells, peeling wallpaper, flaking paint, damp patches, tide marks on walls, damaged plaster, condensation on windows and unexplained moisture within the property. If you notice any of these issues, a professional survey can help identify the cause.
Yes. Many older homes in Portland may have damaged, ineffective or missing damp-proof courses. Rising damp can lead to salt deposits, deteriorating plaster, damp skirting boards and visible staining on internal walls. A survey can confirm whether rising damp is present and what treatment is required.
Yes. In addition to Portland, we cover Weymouth, Dorchester, Wareham, Blandford Forum, Bournemouth, Poole, Christchurch and surrounding Dorset locations. If you’re unsure whether we cover your area, simply get in touch.
Yes. Many of our damp proofing and waterproofing treatments are available with long-term guarantees for added peace of mind. We will explain any applicable guarantees during your survey and quotation.

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.
