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

Repointing- 10 Jun 2026
I tend to only leave a review if it’s someone/something that should be avoided or something outstanding. In this case I can’t recommend DW Brickwork enough and only wished I came across their services a few years back. This was a brick re-pointing job, but DW Brickwork were professional, attentive and excellent at communicating. Due to the weather the job took an extra day but the job was complete and carried out at every stage like it mattered. So this will be a contact I’ll have in my phone for the future. Highly recommend!
