Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Extensions- 10 Mar 2025
Hired paul to carry out works to open up my rear wall and install a new RSJ steel beam for a bifold door. From day one paul helped me out with some issues i was having with my structural engineer design, priced up the works which was very competitive with other builders and While having a visit before works started, i asked paul if he could do some extra works (installation of plasterboard walls and plastering) which he was happy to do. Todd then started works within a few days. Now all the works are finished and im very happy with the finished product. Paul and Todd were brilliant and would happily recommend them to people if they need any works done. I will be using them again in the future.
