    Damp proofing in Garage.

    Posted 06 March

    We recently contacted Max regarding a damp issue in our garage. He was very quick to respond and, after inspection, came up with some different options and pricing. His advice was clear and explained each process well. The option we took involved having to work on our neighbours property and Max was also very helpful in negotiating access. The work itself was carried out quickly and professionally. I really can’t recommend Max enough - he was a pleasure to work with.

    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 recommend

    Insertion of damp proof course, installation of air brick and creating a shingle drain.m

    Posted 28 November 2025

    Max 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.

    Maxwell was a joy to deal with a I would recommend his services to anyone.

    Posted 17 September 2025

    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.

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.
