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

Did a fabulous job on my back yard concrete patio which was crumbling in places and needed levelling. Also suggested adding another step to a rather steep step in place already which made perfect sense and he did a great job with that too. Took 1 day and sent photos of the site after work. Very impressed and very happy with the outcome. I recommend this company and will be using them again on other jobs in the future.

David, Adam and the team they employed were very good. They talked through every aspect of the job beforehand and made the costs clear in the contract. The construction was of a high quality and all done efficiently. This construction was completed during lockdown and the team adapted and communicated well throughout the process. Everyone who worked on the job was polite and friendly and professional. During the construction there were minor changes needed which were accomodated well, even after completion.
