Extensions- 11 Nov 2019
I hired peter of quality first for a single story rear extension and total house refurb in a investment property. After much discussion and advice from peter regarding the costs and Added value, I decided to just do a house refurb, and I can truly say that peter’s input was sound and saved me a lot of time and money. I was able to leave peter and his guys to get on with the job and was extremely happy with the end result. I was kept up to date with progress on a daily Basis and Peter managed to keep close to budget by sourcing materials and appliances from his various reliable sources, sometimes travelling great distance in order to do so. I was so happy with the results that I have used Peter and his team for a much bigger project which is close to completion (on schedule) and will continue to use and recommend peter in the future.

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.

Bathroom Fitting- 18 Sep 2021
During the quote nothing was too difficult and Iustin had some great ideas. 'You tell me what you want and we'll do it.' Great. Day one they caused a leak into the kitchen. Halfway through day two we ordered work to stop because it was still leaking. It took several calls to Iustin to resolve. The leak caused the extractor fan in the kitchen to drop. They fixed at the end but the lights on it don't work consistently. Attention to detail was zero. Floor not sealed behind cupboard, wobbly plaster, streaks of white paint on blue (and vice versa), chipped paint, and tiles not evenly placed, with roughly cut edges. New flooring laid before finishing the walls, dropping sealant, dust and paint on it. Many things had to be redone or changed - but they generally did redo when asked. A window they put in is lower than agreed and the pebbledash doesn't match. They installed the vanity unit on the wrong wall. No dust sheets were put down over kitchen surfaces when drilling through concrete, covering everything in a thick layer of dust. The project was contracted to finish by 4 September, but took until 15 September. Iustin did apologise for this on the last day. On the last day, Marin threatened us because we wanted to wait until the job was finished to send the final payment. At that point we'd paid £500 more in instalments than agreed. Receipts for materials contained items not used or not ours. They took away things that we'd paid for. Overall not a great experience.

Khin and Senh did an amazing job redoing all the skirting in our home. Their quote was competitive and their workmanship outstanding. They helped us source the materials to our specification for a great price, handling all the delivery details and were happy to pick up any bits and bobs to get the job done. Each day they arrived on time and often worked late to accommodate the fact we had carpets coming in the following week. After each day tools and materials were squared away and they would send updates on progress. The final product was top quality and has nicely finished off our home as part of a large book of renovations. Finally any snags that I did notice they were happy to come back and address, I couldn’t have wished for any more from these guys. All the best !

We hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.
