Matt and Adam replaced the boxing in my bathroom and separate toilet, removed the damaged artex and replastered the ceilings before redecorating both rooms. They did a first class job and left everything spotless. I definitely recommend them.

Extensions- 21 Aug 2024
We can’t thank Matthew and the team enough for the build. Great communication throughout and Matthew’s experience and suggestions were welcomed during the initial planning, allowing us to make informed decisions on the final product. Where obstacles were met, they were dealt with swiftly allowing for a much less stressful experience. Our home is now perfect for our growing family as we are able to utilize so much more space.

Restoration & Refurbishment- 17 Nov 2020
Richard and his team did quite a bit of renovation work on our house. We are really pleased with the results. Richard and his team (Wayne and Daniel in particular) were extremely hard working, and got the work completed as quickly as they were able to. Richard had a few issues getting materials (mainly due to the pandemic situation) while completing the work, but kept us fully up to date as to when he would be able to work, and when he couldn't and the reasons why. Richard and his team were very respectful of our house, and family at all times while working. They tidied up every day after working, which really helped as we were living in the house while the work was being completed. The finished result is something I'm very happy with. I would happily recommend Richard, and would be more than willing to have him complete other jobs for me in the future.
