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.

I found Darren to be friendly and professional. His quotes were reasonable. The jobs changed slightly once the work started and Darren took the time to explain the options. Some changes required additional money from me but I was happy to pay as the end result was worth it. I would definitely ask Darren for quotes in the future.

Bellhurst Construction gave me a very detailed quote and were able to start the job promptly. Darrel worked with me on adjusting he quote in order to prioritise the things that needed the most attention. We were held up a few days by the weather initially, but once things were underway I was very happy with how things progressed. The team were polite and worked hard through some of the hottest days of the year! The end result is wonderful and really makes the most of the garden.

M&M Construction did a fantastic job and gave us exactly what we had wanted. From the start, they were easy to work with and understood our needs completely. Even with a few changes along the way, the job remained on schedule and on budget. Their advice was really helpful and the standard of finish was very high indeed. We had access to running water and a working oven throughout the entire process which was very much appreciated and the site was tidied at the end every day. Would highly recommend them.

Hired Ian to Build a single story extension and install new kitchen and downstairs shower room . Crew were very pleasant and very helpful in planning the the job ahead of them. Very pleased with the work carried out looks amazing Having to put up with an awkward neighbor didn't deter them from doing and completing the job. The price put in was very reasonable. When the work was ongoing the area was always left clean and as tidy as possible . I would recommend Ian 100% , and would use him again.

I was very impressed with Krystian, prompt contact after enquiry, was the only tradesman to actually listen to what I needed and produced a quote which met my needs fully. His price was fair and consistent, perhaps not the cheapest but I didn’t necessarily need the cheapest, I wanted the best value with quality and trust. He completed one bathroom within a month of instructing, to a high standard and we were delighted. This gave me full confidence to let the second bathroom which again was superb
