Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Extensions- 28 Jul 2017
Tony and his team recently completed a large ground floor extension. The guys were polite and courteous, on time every day, worked hard through the day and kept a clean and tidy site. Tony was very good at anticipating issues before they arose, making useful suggestions and giving us time to plan. We had a previous bad experience with a cowboy builder and Tony was especially sympathetic and understanding. Tony and his team were always transparent and upfront and very easy to work with. Tony was recommended by neighbours that he had worked for and we would also highly recommend him.

Decking- 14 Jun 2026
Imran and his team did an excellent job removing some decking. He is personable, thoughtful and considerate. They also unblocked a drain for me, sealed up some holes and took away an old table I wasn't sure how to get rid of, and fixed a loose brick in the front garden (without me asking)! He and his team also gave me advice on how to tackle a tricky concrete section uncovered by the decking removal. They were able to get the job done very quickly (within a week of posting on the site) and left everything clean and tidy. I would definitely recommend them.

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

Extensions- 5 Sep 2019
One of the best builders I have ever worked with. PMB take great pride in the work they do and finish to a exceptional level (even better than a lot of premium and expensive builders in the industry). Colin's knowledge about all aspects of building work is unmatched and that shows in the end product that he and his team delivered for me. PMB did a full refurbishment & substantial extension (everything knocked down except 3 external walls) - ground floor ext, first floor ext, loft extension, full re-wire, plumbing, gas, UFH, walls, plastering, fitting, decorating etc. His prices are reasonable and he advised when unexpected costs come up so I could make a decision on what to do. I will definitely use him again.
