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.

Dan and his team were absolutely fantastic. There is no doubt I will be using them again in future.

The quality and speed of work as well as the clean-up was also faultless. I'm really happy with my new slate roof.

Terrible workmanship. Poor attention to detail, poor quality finish. Would not complete the sign off for the job with building regulations.
DESIGN BUILD CONSTRUCTION AND MAINTENANCE
Tony and his team just completed a small kitchen extension which transformed our house. Our cramped dark kitchen is now an airy welcoming space. We had worked with architects and put out to competitive tender. Tony’s price was fair, clear and he was clearly interested in the project. He kept to his price, regardless of the various twists and turns that we encountered in the 13 week build. The craftsmanship of his team is top class - from foundations to finishing they were thorough and precise.

Truly awful experience. The garage conversion was ok (bar the space around the electrical back boxes being stuffed with newspaper) but the flat refurbishment was a disaster. It started ok but as the tasks became more complex, the quality of work declined. The kitchen needed 3 fits, the bathroom has had to be rebuilt, the wiring has dropped into the walls, the joinery is execrable and the radiators don’t work. The job also took 16 weeks rather than 8.
