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.

Sinevir did a solid job on our exterior walls. They paid particular attention to prepping the surfaces—cleaned and degreased everything thoroughly and were careful with the details. They even dug down around the foundation to insulate below ground level, and didn’t charge anything extra for it, which was a nice surprise. They also managed to rework all the ventilation and drainage pipes neatly and precisely, making sure everything was well-fitted and tidy. It’s clear they know what they’re doing and don’t
