I am a self employed Carpenter and Joiner and specialise in fitting kitchens, bespoke/built-in furniture and storage solutions and laying wooden flooring. I also work with a small team on larger projects, consisting of me, a fully qualified plumber, a fully qualified electrician, a plasterer and tiler and a decorator. As a team we fit Bathrooms, Large Kitchens, and undertake Full House Renovations. Although I am a relatively young carpenter, I am not inexperienced and have been doing this sort of work for over 8 years, and definitely feel I have something to prove when it comes to my trade knowledge and quality of workmanship. I am working to build up a profile full of glowing reviews and recommendations and understand this only comes from the best quality work and spot on pricing.

The work completely was of a very high standard with immaculate attention to details. Jerry was punctual from the survey stage to the end of the work. He sorted little snags with the wall, separated the work area with a plastic sheet so the dust was minimised. After each day, my home was left clean and the job was progressing well. The end result looks great and no issues so far. I would recommend them 100%

Hired Ian to Build a single story extension and install new kitchen and downstairs shower room . Crew were very pleasant and very helpful in planning the the job ahead of them. Very pleased with the work carried out looks amazing Having to put up with an awkward neighbor didn't deter them from doing and completing the job. The price put in was very reasonable. When the work was ongoing the area was always left clean and as tidy as possible . I would recommend Ian 100% , and would use him again.

All of the team were personable and a pleasure to have on site.
