Decking- 1 Sep 2020
What a great experience we had with Louis. He is honest and gets the job done efficiently with great attention to detail. He did such a good job with our terrace. We had some problems that really needed a professional solution and Louis planned and executed it brilliantly. Instead of looking for excuses for things that could be a problem Louis had a great solution for everything we came across and was positive the whole time. Would highly recommend Louis, we already have him booked in for more jobs.

Extensions- 16 Apr 2026
I would not recommend this builder based on my experience. Instead of using crushed concrete they used soil to fill the house flooring for underfloor heating. 1 The project suffered from poor communication, repeated delays, and a lack of clarity around responsibilities. There were serious issues with the foundation works, which failed Building Control inspection and now require remedial engineering input before works can proceed. The site was also left incomplete and not in an acceptable condition. Despite substantial payments being made, key documentation, technical responses, and follow-through were lacking, leaving me to resolve major compliance and structural issues independently. My experience has resulted in delay, additional cost, and considerable stress. I would strongly advise others to ensure there is a detailed written contract, clear scope of works, and defined accountability
