    General FAQs

    • How Much will it cost to remedy my damp problem/ can you give me a price over the phone? Every Damp Problem will be unique in terms of the extent of work required and the size of the problem, depending on what the issue is. It is also dependent on what products are used which in turn will affect the price.
    • Are your treatments guaranteed, if so for how long? Yes, most of our work is guaranteed for 20 years.
    • How long do I need to wait to redecorate after work and replastering? Non vinyl emulsion paint can normally be used after approximately 3-4 weeks. Impervious type of wall coverings such as vinyl and washable papers or paints should not be used until the walls have fully dried out. Full drying out may take up to one month for every 25mm depth of wall. Drying times are dependent on various factors such as the ventilation provided during the drying process, the room temperature and the extent of dampness initially.
    • How long is the report and quotation of works valid for? Once we have inspected your property, the quotation provided will be valid for 3 months. After this time we would need to review the quote, however most of the time the cost will remain the same for longer. If the report is over 9 months from the date of inspection another visit would be necessary.
    • What experience do your employees have? All surveyors carrying out the initial inspection have extensive experience in the remedial industry and are qualified with Certificated Surveyor in Remedial Treatments (CSRT) or equivalent. As of 2018, this certification has changed to Certificated Surveyor of Timber & Dampness in Buildings (CSTDB). All of our installers are employed by British Damp Proofing directly and no work listed within a report is sub contracted out.
    • Do you charge for surveys? Surveys are subject to a cost. Our head office will advise you on the exact cost and other other queries you may have.
    • How soon can you come out and survey the issue? We will usually visit the property within 7-10 days of receiving the inspection fee. During peak periods this may be longer.
    • Can your surveyor give me a price on the day? In short, no. Our surveyors carry out the initial inspection and take measurements that are required. Their notes are then emailed to the office and costings calculated. As their notes are sent across to the office digitally and the reports are emailed to the client unless requested otherwise, you will receive the report within 2 business days.

    An exceptionally professional, knowledgeable and honourable company.

    From the initial inspection through to the detailed follow-up guidance, we were treated with patience, respect and complete honesty. The surveyor (Mathew) took the time to explain the difference between condensation, mould, salt contamination and rising damp in clear terms, and answered every question thoroughly.

    What impressed us most was the complete absence of pressure or unnecessary upselling. Rather than recommending the most expensive and disruptive work immediately, he advised us to begin with the least invasive, most cost-effective measures and monitor the results before committing to anything further. That level of integrity is rare and deeply appreciated, particularly as the property belongs to elderly parents and we needed to know that any recommendations were genuinely in their best interests.

    The advice was practical, balanced and clearly based on experience rather than salesmanship. We now feel far better informed and much more confident about the next steps.

    Should further remedial work become necessary, this is unquestionably the company we will return to. I would recommend them without hesitation to anyone looking for honest, expert advice and exemplary customer care.

    We had serious damp problems in our lounge so we called in BDP to fix it. They took all the plaster off some walls, spayed the brick with fungicide, installed a membrane and a damp course. The guys turned up early, did a great job, were tidy and polite and finished on time. The lounge should now be liveable.
    Response from the owner:Thankyou for the positive review Dave and we are glad the work went well and was finished on schedule. All the best, The BDP team

    On behalf of Priceville Properties Ltd, I would like to comment that once again British Damp Proofing Ltd of Alford Lincolnshire have completed damp proofing works successfully and satisfactorily at one of the Companies rental properties.
    British Damp Proofing have worked on numerous Priceville Properties rental houses over many years and have always done a great job in a timely and satisfactory manner. We can highly recommend them.
    Response from the owner:Hi Brian, thankyou very much for the recommendation and the kind words, look forward to working with you again in the future, many thanks , The BDP Team

    I recently used British Damp Proof for work on my new property and I’m really happy with the service I received. The team on site were friendly and professional, and they did their best to keep disruption to a minimum while the work was being carried out. They kept me updated each day and were always happy to answer questions.

    I also want to mention the office team because they made the whole process much easier. Every time I got in touch they were friendly and easy to talk to, always got back to me quickly, and took the time to properly answer any questions I had. Nothing ever felt like too much trouble, which really makes a difference when you're dealing with work on a new home.

    Overall a really positive experience from start to finish and I wouldn’t hesitate to recommend them
    Response from the owner:Morning Rebecca, thankyou for the positive feedback. It's much appreciated from all the BDP team, many thanks !

    I called in BDP because I noticed that the skirting in my library/craft room was rotting away. Matthew came around some weeks later (I went down with the flu when he was originally due to come and then the Christmas holidays came around hence that delay.
    Matthew said that because of the damp Weavils were eating the damp wood hence the wood dust I had found on the carpet. The dampness he believed was due to polystrene wall insulation blocking the air bricks.

    Most of the furniture was in the room at the time of his visit so he was limited in what he could appraise, but he said it looked like half of the floor would need to be replace as it was sinking and very spongey in the area by the window where the skirting damage could be seen. There was a wait period for the work to be carried out but a) I expected this as they carry out a lot of work and have to schedule things and I needed time to clear my books and bookshelves as I have a bad shoulder.

    When the day arrived for the workme to come an =d commence the work, they found that it was worse than expected. The whole of the floor was starting to fail and the joists under the floor were damp and rotting badly. The whole floor would need doing. This meant that some units and shelving would need to be cleared and removed. The workmen kindly took them down and moved them into other rooms for me so they could do the necessary work.

    The men who came to do the work were curteous and hard working. They took out the old flooring and joists, stopped anymore of the polystyrene beads falling through and blocking the vents by way of a sleave around the internal edge of the airbrick, Instaled new joists which they insulated with polymer foam where it touched brickwork to stop any damp reaching it. They then relayed the floor using MDF boarding and replaced the rotten skirting.

    The job took 3 days to complete and they took away all of the old timbers and swept up before they went.

    They made a good job and there is the peace of mind of a guarantee for the work done.

    I would recommend them.
    Obviously twice the work meant twice the cost, but with that comes the comfort of knowing that I'm not going to go into the room one day and find the units have fallen into the sub-floor area.
    Response from the owner:Hi Nicola, thanks very much for the 5 star review, much appreciated and we are pleased with the service you received and that your issue was sorted. Best Wishes , The BDP Team

    I asked for British Damp Proofing to come to my very old house as I was concerned about some blown plaster. Mathew arrived promptly on the arranged day and he was clearly extremely knowledgeable and I immediately knew I was in the hands of a real professional. He very quickly put me at my ease as he explained what was needed. And amazingly his honest assessment meant that I could solve the problem myself using a product he recommended. Not only that, but the money I had deposited for a survey to be done was returned to me that same day Mathew said he wouldn’t charge me for his time and advice. How rare is that?!
    Response from the owner:Thankyou for your kind review Diana, from Matthew and the BDP team
    Lisa Couper
    I've just had quite extensive damp proofing done and I'm very pleased ,obviously the proof will only evident many months further on, but I'm confident it will all be worth it. The gentlemen were professional and courteous. They did their best to minimise the disruption and to clear away as much as they could at the end of each day. When finishing they advised me on how to proceed with redecorating, sizing the plaster once its dry etc.
    I'd have no hesitation in recommending them to any of my neighbours..
    Response from the owner:Thankyou for your 5 star review Lisa, i will feed this back to to the guys ! Many thanks, The BDP Team

    David Turner
    My hallway and metercupboard needed treating, breathable membrane fitting and replastering. The polite friendly team came as arranged and completed the works to a very high standard within three days. The workmen minimised the mess by removing old material and cleaning every night. I would recommend British Damp Proofing to anyone with similar problems.
    Response from the owner:Thank you for your positive review David. We are glad you were pleased with the outcome and it was a pleasure doing work for you. All the best, the British Damp Proofing team
