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.

We had them in to install insulation in our upstairs floor, replace the sub floor, replace some lights, install a loft hatch, and board out our loft. On top of this they discovered a problem in our roof that they fixed. We were incredibly impressed by all of the staff that attended on site. They were friendly, polite at all times, and worked really hard, to a high standard. I couldn't recommend James and his team more, and we've already started talking to them about a further project.

Very pleased with the work done by Sinevir. I hired them to build a reinforced foundation for an extension, and everything was completed to a high standard. They worked carefully, met deadlines, and used quality materials. It’s clear they know their job well. The foundation is strong and reliable. Thanks for the professional approach!
