Bricklaying- 21 Aug 2019
Mark has done a fantastic job building an external brick wall for my garage conversion. The work is so good I cannot really tell where the door opening was. He promised to finish in 2 days which is exactly what he did, he cleared all rubbish and cleaned everything before leaving. Very friendly, great communication, and great value for money. Highly recommended. :)

Very pleased with our finished extension. Originally we were just getting luke to do the shell of the extension but after seeing his work and professionalism we got him to do the inside aswell. We were very happy from start to finish. They are unlike other builders that come and go as they please. Luke stuck to his time scale and stayed on the job from start to finish. Would highly recommend .

Ethan Courcoux Masonry Specialist
Rating: 5 out of 5
Extension Builder in Chepstow
I’ve been a qualified bricklayer/stonemason for 10 years and started working solely for myself at the start of 2025. Trying to accommodate only homeowners and small contractors instead of larger companies. I have expertise in extensions, chimneys, rake out and repointing, and installing structural steel works. I’m also very comfortable using lime mortars for building and maintaining properties. I’m currently trying to be more open an honest as builder to try and reassure all my clients. I also touch base with my clients after all my jobs to make sure that they’re satisfied with the work a few weeks later and that no issues have arisen.

What experience do you have with similar extensions in Chepstow?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Chepstow extension builder’s ability to deliver a result that meets your expectations.
