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.

one of the best carpenters i had. Old houses are tricky and unlike others Andryi privileges doing the job well over doing the job quickly and then disappearing . He is a safe pair of hands, he is self-driven, doesn’t need to be managed and the results have always been meeting expectations. He has installed french doors, skirting boards and garden gates

I contracted Alfie to refurbish a large area of Cotswold stone terrace and pathways around my home in Godalming. The terrace was a mess. Alfie and his team made a great job of removing all the old cement mortar pointing, relaying loose slabs, re-jointing and tidying up the area, including rebuilding the front door step. His young team were friendly, polite and hard working and I am happy to recommend them to anyone considering hard landscaping work. Everything was delivered to the agreed plan.

James was hired to fit 5 internal doors. It took him 3 days, and the work was careless, lazy, and full of mistakes, excuses, lies and frustration. He blamed the doors, house, locks, anything but himself. I wasn't going to leave a review, but after he left I was able to fix —by myself— issues that he tried to gaslight me into believing it was the best possible outcome. I suspect his "27 years of experience" was made up, and the problem was nothing but absolute lack of skill, care and work ethic.

Dan is a force of nature, as anyone who’s met him will agree. He and his team were always dedicated, hard-working and good natured. I would recommend Dan and his team to anyone, especially for a big renovation project like this, which involves working with other parties, such as structural engineers, kitchen designers and installers, as he works with them and takes away most of the pain. The quality of the work is excellent and he always came back to complete the snag list (even 3x for our thresholds).
