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!

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.

I cannot recommend this company highly enough. Tudor & Darius did a brilliant job re-decorating my 2 bed flat, moving furniture around as needed without any fuss. They work quickly and meticulously neatly & cleanly. Tudor gave good advice on what type of paint to use on my woodwork, I didn't want it to look too shiny so chose eggshell. Whilst here they also sanded and re-hung my front door to prevent it from sticking. I would definitely use them again.
