10 Removing concrete compromising DPC
Posted 07 December 2025
Max was great from his instant diagnosis without fuss and over complicated explanation. Rising damp inside caused by a small section of concrete drive being too high . Max created a channel with shingle but also repaired the part of the DPC too. Work done quickly and a fair price charged unlike some of the larger companies who would probably charge more just for the “report”. Highly recommendVerified reviewerJob location: SM3 - SShirley B

Job location: TN8Max was quick to arrange a time to come to the house to look at the job and to then provide a written quotation for the work. He was also able to offer a time to do the work very quickly and it is all looking good. He has given additional advice on ways of managing condensation within the house. His work is guaranteed and we are happy with it all. 10 Brilliant, glad I chose this provider

We recently contacted Allwood Preservation when we found a few items with woodworm in our garage. Maxwell visited us properly and gave us clear advice on what we should do to ensure it hadn’t spread any further. The work was carried out promptly and with minimum disruption.Verified reviewerJob location: CR39.67 Damp solution in Sutton

Allwood Preservation came round to provide a solution to a rising damp issue by our back door in the kitchen, we also sought two additional quotes too. Maxwell's extensive knowledge and honesty was greatly appreciated, so we accepted his quote. On the day of the works, he arrived on time and worked efficiently, with care and extremely tidily. We would thoroughly recommend him and Allwood. He went above and beyond to help us and we are grateful. Thank you.Verified reviewerJob location: SM19.67 Honest advice.

Great experience and a very honest person. Max came to assess our house for damp. Max looked outside the property, inside and asked what our concerns were. Max was honest and said that the issue was more condensation and gave us some further pointers to reduce it. His honesty was appreciated and meant no unnecessary cost for us.Verified reviewerJob location: RH6

We are a small family run business and have been trading since the 80s.
I have been in construction since 1969 having served an apprenticeship in bricklaying which I gained a distinction. I worked on many prestigious projects over the years, in the city and west end of London including the Victoria and Albert museum, and many more.
I came into the remedial side of the business in the early 80s,and have been busy treating Damp and Timber problems ever since. We have resisted growing into a large firm because we like the hands on touch that only a family business can offer.
