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.

Half the laminate was laid, but I noticed the pattern joins didn't match up. They were unsatisfactory and I pointed them out. The tradesman was happy to lay the laminate again. This time it was done well. I'm now delighted with the overall appearance of my floor, although there are still some small areas, especially by the skirting, where the laminate hasn't been secured by the trimming. Apart from these small things, the service was friendly and the job was finished on time. I would use them again.

Unbeatable I found quay builders via a google search and liked the work I see on his website. Christian and his grandfather. Designed and completed built in wardrobes, storage, and a computer desk in my loft. Literally can not recommend him enough. Really quick at what he does to a very high standard. Prices certainly unbeatable. Would not hesitate to have Christian back to do more work in my home. Very genuine guy. You will not be disappointed.

Highly recommend Ben for plumbing and rendering work! He did a fantastic job — everything was completed to a high standard, on time, and within budget. Very honest, easy to communicate with, and offered practical solutions without upselling. His pricing was fair and transparent, and the quality of work speaks for itself. It’s rare to find someone so reliable and skilled these days — will definitely be using him again!
