Extensions- 20 Nov 2019
Matt of Pro Build (East) Ltd. was instructed to complete a home extension on my Victorian Mid-Terrace property at the beginning of July 2019. Matt initially replied to my MyBuilder advert promptly, came to view the job within days and could start the next week (in hindsight, probably not a good sign). He started work on the Monday, providing a quotation and an expected completion date of 3-4 weeks later for the complete extension including removal of waste, plastering and external rendering. Throughout the build, Matt's communication was prompt, replying to emails, phone calls and text messages mostly within the same day. Unfortunately, on a number of occasions problems arose with the project and I was frequently to blame for certain aspects, for example it was my fault that the roof could not have slates because the roof was built at a low pitch - however the quote included slates? The quality of workmanship throughout the build was very varied, requiring Matt and his team to return a number of times to re-do work which was deemed unsatisfactory by me, other workmen and the building inspector. There is quite often a number of excuses for why work has not been done, or why it has been done to a low standard as opposed to correcting the issue without argument. In the end, the whole build took 14 weeks to complete and remained to have a number of snagging issues, I would not personally recommend this company for larger works such as this.

Conversions - General- 7 Oct 2025
I cannot recommend Jake highly enough, the best experience I've had with a builder, ever. I'd given up hope that builders like him existed. Came on time, quoted on time, in detail, twice as the spec developed, which was for a wide range of internal and external work including a garage to studio/home office conversion, new bathrooms, rendering and plastering, roofing including roof lights, flooring and earthworks. Once contracted, he and his team turned up when he said they would, he was always responsive, and solutions-oriented when unexpected issues arose, as they always do. He had good attention to detail, was neat and tidy, nothing was too much effort, and he was always pleasant and open to ideas and changes. He was fully detailed and transparent in his pricing, and hands on to ensure the job got done on time - a great work ethic that is so hard to find. His business deserves to flourish, and he's definitely the only person I'll use for future work.

Groundwork & Foundations- 30 Jul 2026
Joe Cook and his team did the groundwork for us for a swim spa. From the initial visit, he was prompt and gave me confidence that he understood what needed to be done. He went over and above expectation in every way. He spoke to the distributor of the swim spa to check specifications, and checked every detail. We had Joe and 3 team members over 3 days working with us and they were all polite and professional. He contacted neighbours of ours to let them know what was happening and keep them informed. When we had issues with the delivery of the swim spa, and both the distributor and crane hire were unable to agree how to proceed, even though Joe's part in the job was done, he took control and made lots of calls, pulling in personal favours to save the day for us. Before they left each day, the site was left tidy. He even smartened up our driveway for us! We will absolutely be having them back for future work.

Restoration & Refurbishment- 28 Apr 2019
The work included: knocking out part of a wall and creating a new ‘alcove’ area to enlarge one room, removing a door and making good the wall, re-plastering of ceilings and walls, laying new flooring, various electrical works and installation of a new radiator, plus numerous other little bits and pieces. Tony gave me good advice at the planning stage about the various jobs I wanted doing which ended up saving me considerable, unnecessary expense. The price was a fair one and came in on budget. Tony kept me fully informed at all stages. Tony’s team were friendly and helpful. The final result is lovely and well finished. For balance, the only negative was that the job did over run by a few days; however I must add that Tony and his team did their very best to catch up including working weekend days at no extra cost to me. I would not hesitate to use Tony’s services again, and, in fact, fully intend to.
