Reliable, honest and communicates well. Kevin has built a garage and single storey kitchen extension for a reasonable price. I hope to use him for other work in the future.

Morgan and Mike contacted me on the day of posting my job, visited that same afternoon and sent me an itemised quote that evening. They understood that the job was urgent and turned up on the appointed day, at the appointed time. Both my wife and I found they were happy to explain their work and to give us options. The work was neat, efficient and just what we needed. We will definitely use them again and would be happy to recommend them. Very pleased.

Jason and his partner fitter a new bathroom for me, including all new plasterboard etc as water had gotten behind the old tiles. They tiled the floor and walls for us also. The bathroom looks brilliant couldn’t be happier, more than happy to trust them when not at the property and to top it all off when they were finished I went out to my garage so that I could take all of the rubbish to the tip and they had beat me to it. Will be hiring again for my second bathroom shortly!
