Conversions - General- 3 Apr 2026
I originally left Stuart a five star review because the workmanship and communication were excellent, and I booked him to return to complete the internal works on our extension. After paying a deposit, the work was due to start on 27 June, but Stuart never turned up and stopped communicating. His partner later asked if I could delay the work for a few months because he couldn't contact me. When I explained I couldn't wait and politely requested my deposit back, I was blocked. I have now been left with no option but to take him to the Small Claims Court to recover my money. It's a real shame because the original work was of a high standard, but I cannot recommend someone who takes a deposit, fails to return, and then ignores all communication.

Promised to come back and finish The fence and the toilet never come back despite numerous phone calls. I have leaking toilets in the wall big pigments of dampness on the wall paper on the wall adjacent to toilet. Promise to do the roof tiles then he said I cannot do it. Fitted the kitchen units wrong and did not connect the sink overflow pipe to the macerate ( leaking water under sink. Flooring tiles not even still have prominent corners . Front driveway is cracked as he promised to dig and put concrete but last minute changed his mind and put only cement and new slaps. Water pipe outside house is leaking . The stairs carpet and the wooden stairs not painted rightly and the carpet is not fixed right it is out.

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.

What experience do you have with similar extensions in Brockley?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Brockley extension builder’s ability to deliver a result that meets your expectations.
