Damp Proofing- 11 May 2026
My experience with Samuel was excellent. He provided a professional, comprehensive, and high-value damp survey for my basement. The final report was very thorough, including a detailed technical assessment and numerous photographs that clearly explained the situation. What really stood out was his willingness to answer several follow-up questions regarding the specific remedial work he suggested. His expertise helped clarify that the issues were environmental rather than structural, which provided great peace of mind. Highly recommended for anyone needing a clear, honest, and professional assessment.

Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

Extensions- 3 Jan 2021
Reg was professional and organised from start to finish. Very tidy while working and always polite and cheerful. He was pretty much spot on with his timescales, working through weekends to make up unexpected delays in stock delivery. He managed to perfectly match the bricks of the porch so, as it is tied in, it looks like it’s part of the original build. Really impressed with every thing. We will definitely hire him again - in fact we have already asked him to quote for another job.

What experience do you have with similar extensions in Rainham?
