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
