Groundwork & Foundations- 7 Jun 2026
I got KDM in to install a 75sqm concrete base and was very impressed with them for a number of reasons. - Firstly, their work was excellent. The finish of the base was excellent and they put a lot of effort in to get things perfect. - They were reliable. They showed up when they said they would both for estimates and to actually do the work. Sadly I cannot understate how rare this is today when working with contractors. Communication was excellent. - They're very honest. They gave me a quote based on my requirements which was a little high but manageable. At the end they came in under budget and gave me back the difference. All in all I would be very happy to both have KDM back for more work or to recommend them to anyone else.

Bathroom Fitting- 14 Apr 2023
Jordan and his team did a first class job of renovating our small cloakroom. Punctual clean and professional workers. We are both elderly and it was quite a daunting prospect inviting workmen into our home to have this refurbishment carried out. Both we and our home were treated with the greatest respect at all times. We felt we were in safe hands and cannot thank him and his team enough for all the help they gave us . Would have absolutely no hesitation in recommending him to anyone. Thanks again guys … you did a great job here .

Started with a kitchen from 1926 that had only a poor modernisation in 1981. Original Plaster needed improving, and many more gremlins....but.... Build Right fitted the new kitchen and did a massive amount of prep work, improvements and finish to an extremely high standard. definitely recommend!
