Carpentry- 18 Feb 2026
Josh gave me a fixed quote for the job and a clear explanation of how he would do it. He kept it touch at every point, arrived on time and respected my property inside and out. I could not be more pleased with my new bannister. He has done an amazing job, moved furniture back into place and cleared up so well there was nothing left for me to do. I could not recommend JLA Joinery more highly.

Bricklaying- 17 Jun 2026
When I posted the job on My Builder I was facing a deadline after letting go the existing contractor because of poor communication. After contacting Richard and Paul they couldn't have been more accommodating, nothing was too much trouble and as I have keen interest in details they were easy to work with. They were able to accommodate my project at relatively short notice which was fundamental to keeping the project on the original timescale. The team were always punctual and always were on site when the said they would be. Their work ethic is a credit to them and was reassuring as we were plagued by some poor weather. To me one of their best attribute is their communication, they kept me informed throughout the project and we discussed the progress everyday. In short they are a punctual, hardworking and reliable and I can fully recommend them.

Extensions- 24 Sep 2020
Arran started the works on the day agreed and ensured the build continued on schedule to completion. His attitude to work was very professional and his bricklaying finish was quite meticulous. Very pleasant and obliging to deal with and nothing too much trouble. Have since recommended him to another friend which is something I would never consider unless I had been perfectly satisfied with his works for me.
