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.

Fired him for appalling work, no-shows and delays; see his other bad reviews. He's a middle man; does not do any work; got others to do it like a plumber, then a tiler the next day; slow work made worse when someone messed up or did not show up. Ali only shows to deliver materials or check work. Quick to reply when wanting the job. Slow/no response once job starts thinking you wont cancel. Materials I paid not returned; take every receipt and check you keep/use every item as he will even for wipes/tape

James was friendly and knowledgeable. Gave us plenty of advice about how to properly look after the woodwork of the shed. Had clearly done similar work plenty of times before, and knew how to handle the task. Would recommend

I did not hire this company. They came to assess the job and promised to send me an estimate by email. However, despite several messages to them from myself, they never had the courtesy to respond or send me a job estimate. I would have zero confidence in this company, and obviously their customer relations needs improvement. Consequently, I am still seeking a tradesman to do the job.

I was impressed how Amir took the job very quickly - he arrived to work a few hours after seeing the post. He was very friendly and polite and was happy to take the job. However, I really would not recommend him for carpentry work. This was an easy job, where the carpentry was already done and it just needed fitting. He arrived with the wrong tools (had to use mine) and very poorly fitted the cupboards and shelves, to the extent I had to pay another tradesperson to fix the job. The finish was awful.

Fantastic work. Andy is very professional and knowledgeable. Prompt, friendly and very competitive prices. We are building a 2 storey side extension and Andy is doing all the building works. We have a very difficult set of footings which involves a line of trees close by. Foundations passed by Building Control with flying colours. Very satisfied and Andy will be quoting for other work I have planned and I am sure we will be working together for sometime now. Would recommend him to anyone.

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.
