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.

Restoration & Refurbishment- 13 Aug 2019
David and his team were excellent. They are always on time and very professional. They always cleared up at the end of the day thereby leaving very little dust or dirt around the house. No query or issue was ever insurmountable; the answer was always "no problem", which was a joy to hear when having such a large project to do. Each different team i.e. electrician, plumber, arrived exactly on schedule so there were never any delays. The end result was amazing. I highly recommend David and his team.
