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.

Lance Tait and Longstroke Plasterers quoted to remove a load bearing brick pillar in my kitchen. The started when scheduled and finished on time. The work was completed in budget. The skill and professionalism of the workers was amazing. House left clean and tidy each evening. I cannot praise Lance and his team highly enough. Great Job.

Commissioned C and J developments. To build an attached garage. At the start of the project we talked through any issues as they arose and agreed how they would be rectified. However as build progresssed the quality of work deteriorated Brickwork bowed in side and rear walls. Joists for garage roof cut at different lengths and not cut to match the angle of the wall one joist packed out with old pieces of wood. Walls either side of rear door not aligned. Stopped work due to poor standard of workmanship

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.

Poor communication and lack of project management skills and honesty leaves something to be desired of this company. A 4 week job turned into a 16 week job due to the fact that the sub contractor was not released monies to purchase materials although I paid a hefty 30% deposit and further 30% before up to roof level. I would recommend Carl the sub contractor that did the work but wouldn't recommend CM Masonry. The sub contractor did a good job thankfully so the end result is good.

Made a total mess of a small extension. Quoted 2 weeks and after 7 I sacked him off as we were going nowhere. Massive list of his work didn’t comply with building regs and ended up fitting a purlin to roof as he used wrong sized joists. I now have bits of roof hanging off after max 30 mph winds Even managed to cock guttering up so down pipe is nowhere near drains. Roof leaking and I have had to sack him off and pay another load of cash to a set of lads who can do the job. Avoid or he’ll bankrupt you

Nice guy but let me down terribly. I needed 3 rooms to have new ceilings. A messy job and taking the old ones down was fine, but they ran out of time, failed to complete the job leaving gaps in the plaster on the walls and failed to skim the plaster board on the ceilings. Shocking result- they were too concerned about the large job they had and left my rooms in a shocking state.
