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.

Andriy went above and beyond to get the project done really well and quickly. Will definitely be asking him to help with more work in the future.

Behrooz and his team installed engineered wood from the Colour Flooring Company in my property over several days. Behrooz and his team did a careful, high quality job with good attention to detail. The property is Georgian and had some tricky areas to navigate, which I was consulted on when we needed a discussion. The quote for the work was fair and the team took care to tidy up thoroughly. Lots of flexibility shown at all points. Recommended.

They provided the materials and kept me informed in the process. They are hardworking and I saw a huge difference for every day they came.
