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.

Igor and his team did a great job for me in renovating and updating a Grade II Listed townhouse in Clifton. The scope of works included extensive repairs, all new plumbing & electrics, a new staircase, kitchen and bathrooms, and complete re-decoration throughout. Igor was always extremely efficient and helpful, and overall I was happy and satisfied with both the price and the quality of work, although it did take a bit longer than expected to complete.

ROOF LEAK AFTER HEAVY RAIN After picking up the job on Rated People Adam attended and within 48 hours provided a broad quote for the work needed, additionally cautioned me as to the possibility of necessary work not immediately apparent at first sight. Adam and his friendly, competent team arrived as arranged, did a good job to roof verges, Ridges, Valleys, replacing tiles and cleaning up the site daily. Three weeks later after more heavy rain and snow my roof is sound. Thank you! Highly commended.
