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.

Fatjon did the most fantastic job installing my bespoke Plantation Shutters into the bay window of my Victorian cottage. He was punctual, considerate, polite & the level of his craftsmanship was first class. The shutters look amazing & so much better than I had expected because of his finishing touches. In fact I asked him back the next day to do some other work for me. I honestly can’t recommend him highly enough.

ended up putting a completely wrong colour of silicon in my bedroom which completely spoilt the look despite him saying it gives a different kind of look. I was completely new to doing a house, so didn’t know what will work and what won’t. Ignoring the choice of colour part, there were smudges of silicon at many places and i wouldn’t call it a neat job per my standards. But each one could have different standards.
