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.

Graham and his lads were great. Would highly recommend for your building works. Was always open book about costs and plan of action, spoke on the phone regularly and was always easy to get hold of to give you that piece of mind. Full kitchen extension 5m x 3m from start to finish. Trusted with access to the property and never had any issues.

Nick and his partner were a real pleasure to deal with. Nick came up with a great design for the bookcase we wanted for our cafe and was more than willing to work late into the evenings to get the job done out of opening hours. The workmanship and finished results were second to none and the shelving is getting a lot of praise from our customers, some who want the same thing built in their homes! I would highly recommend N J Carpentry to anyone looking for high quality carpentry work at reasonable prices.

We used Ervins to design and build a bespoke radiator cover, encompassing a shoe rack, in our hallway and to make and fit various shelving units around our home. He was personable, prompt and reliable throughout our dealing with him and provided a service that was excellent value for money. We would definitely use him again and wouldn't hesitate to recommend him to others.

Timing was not an issue. Unfortunately quality of the work was. We since were able to find someone we were much happier with, who did proper preparation and did not ruin our belongings by getting paint on them.

Dimitar has done a brilliant job. He is a well organised, highly skilled craftsman who takes care about his work. He doesn't take any shortcuts, he goes back to the basics and builds it up - although this takes a little longer the end result is very high quality. He checked all the details with us from the handle positions to the way the doors open. He had good innovative solutions to two difficult issues. We absolutely love our new kitchen and would not hesitate to recommend him. Thanks Dimitar!

Imer recently helped me remove old kitchen cabinets and a light rail and install new ones. He was super professional throughout the whole project, promptly responded to all my emails / texts and went above and beyond to make sure the job was to a high standard. I was a little hesitant because he doesn't have too many reviews (he explained most of his work comes from word of mouth), but I'm SO GLAD I DID. Will definitely call him for my next project!
