Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry
Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.

I have good prices and my prime trade is plastering
AVOID. Let us down very badly. Came to site all smiles and agreed a price and shook hands. We confirmed the price and scope of works in writing and he confirmed back to start and finish over the bank holiday. Our client had arranged to stay elsewhere. The day before he was due to start, he cancelled with a lame excuse. Totally left us looking very stupid and the client very upset. Do yourself a favour and look elsewhere.

We also have a joinery factory in London. We manufacture any made-to-measure woodworking such as shop display and counters , kitchen units, wardrobes, TV stands, dining tables etc - you name it, we do it.
Behrooz was hired to install underfloor insulation for soundproofing and engineered wood flooring in our flat. He was always on time and let us know when his working days and hours in advance. During the process, additional works arose as it's a Victorian house, which Behrooz explained in detail. We proceeded after discussion. We were on a tight deadline, but Behrooz and the team made it happen, even willing to work later hours, which I appreciate. Highly recommend!
