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.

Ken is a brilliant plumber. He put gas central heating, boiler, a waste pipe through the house, and plumbed in 2 bathrooms. He is very friendly, patient and talked me through all the options. And he did everything on time and on budget. I would definitely use him again. Stella

They turned up on time every day, worked 7 days a week to get the job done, listened to what I wanted. They cleaned up after themselves every day and just worked constantly throughout the day.The price quoted was very competitive. I would definately use them again. The job that I had done was a complete bathroom refurbishment and roof repair.

Frank designed, implemented and completed an extremely difficult job to a very high standard. Even after discovering hidden issues after completely going back to brick wall Frank was never phased and gave us options on each case. Frank and his team made what could have been a stressful time a walk in the park. We will be using Frank again, finding reliable tradesmen is difficult these days. I recommend Frank to anyone who's is after an efficient and professional tradesman. Thanks Frank.
