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.

Brian and his son Patrick did an excellent job redecorating our house. The standard of work was very professional throughout, with great attention to preparation and finish. They kept exactly to the agreed timeline, worked efficiently, and were reliable and easy to communicate with. They also cleaned up properly at the end of each day, which we really appreciated. We’re very pleased with the result and would happily recommend Brian and Patrick to others.

Amazing service From Alen and his team. His quote beat the competition by far, but without any compromise on the windows. We were only planning to have new wooden double glazed windows for the front of the house, but were actually able to have new windows for the whole house.

Very unhappy with work completed. Unsafe working practices by team. Roof has more leaks than prior to works starting Damage to asbestos panels Poor workmanship Optimal roofing now ignoring my attempts to contact them. I have had a full house refurb using many contractors and have never experienced anything resembling the appalling standards set by Optimal or their lack of attempt to resolve . DO NOT USE THIS COMPANY. I am now 1k out of pocket and will have to pay another contractor to fix damage caused
