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.

I didn't have to buy anything. I just went and took pictures of all the items i wanted from B&Q and they went and collected the items and paid for everything at that time. They provided all receipts and told me of any additional costs of stuff that was needed to complete the work. Iva's dad and another worker arrived on time everyday. 5

I want to thank Mariustz as he has done a great job. The initial job was for some doors trimming, but we agreed also on some other jobs which were needed such as changing the door side opening, locks change, putting biddings and corners and new architraves. He is very kind, detailed and generally a very nice guy to talk to. I will definitely ask him again to do some other works for me.
