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.

Came to fit a new shower tray and enclosure 19/12 and fit a lintel over a fire which was done well.However the shower we found 2 days after, due to waiting for sealant to dry, is unusable as the water does not drain away and floods the floor, also the tiles they put on around the shower fell off the wall as they were not stuck on properly before grout. I had paid them the day the job was done .I asked Paul to rectify it and he said he would on 31/12,then didn't attend & told me to get another plumber !

John is a really nice guy, I'd love to rate his actual work but after chasing for quotes for a few weeks I should have realised. I've been constantly chasing for three months to get the work complete. No option but to return insurance cheque for payment for the work I can't get completed and go through the whole process again with someone reliable. Shame as i said he seemed a really nice guy!.

I have been in the trade for many years, (17 years) I have recently gone on my own, and my business is doing really well, I take pride in my work and it's what I enjoy doing. I always hit my targets and it's shown because my business is doing brilliant

Martin was quick to make contact with me and arrange a time to quote. He came to my house with his wife and they were able to give me really good advice and a quote on the spot which was appreciated. I didn't use Martin on this occasion more due to my own timings then anything else but would certainly look to contact him in the future for any other jobs required.

Hi my name is Jonathan I’ve been a multi skilled carpenter for over 20 years. My core trade is carpentry and I am also a very competent plumber and tiler as you will see from my reviews and before and after pictures. I enjoy my job and with great job satisfaction I aim to provide a professional service with quality assured.. I have been off rated people for a few years as I began working for a large maintenance company and with everything happening in the world I’ve decided it’s time to start up again. So I’m ready to go! I have full liability insurance and I can provide certificates if requested of my NVQ L3

George Bell came to work on some damp related issues in my flat in feb. since having completed the works the problems which first occurred have turned worse and George has been unwilling to get back in contact with me, despite chasing him for 5 months which only reaffirms that the job was poorly undertaken. The company main reception also seems to be a virtual reception so you can never speak with anyone helpful
