Kitchen Fitting- 16 Jul 2026
Good guy, did the work but there is lack of finishing in the job. I appreciate his honesty that he made error and rather than hiding, he accepted and fixed it for us. Kitchen looks good but it could be better with little bit more perfection!

Extensions- 13 Jul 2024
Late review. Ste and the fellas built a wrap-around single storey extension for us in 2021. I can't recommend him highly enough. It wasn't the easiest build due to poor drawings we had from the architect, but Ste went above and beyond to make sure we had the extension that we wanted. Ste and the lads were positive, friendly and always had solutions to any challenges that came up. They also stuck to the original quote as much as possible, despite rising costs of materials at the time (2021). My wife and I worked from home for the entire build (about 4 months start to end), which wasn't ideal, but Ste and lads helped to make it work for us. 3 years on and we're well and truly settled and loving the extension. We're not sure that we'd ever want to go through a similar build again (at least not while living and working from home full time), but if we did then we would want Ste to do the job. 5 stars.

I gained my NVQ level 3 in bricklaying straight from school and have worked as a builder for 20 years. I have worked for several companies in all aspects of building. From maintenance work for local authority to building private extensions on houses. I have a lot off experience in assessing all issues with properties and recommending what needs to be done, like damp issues or lintel replacement. I always work following building regulations and never had any of my work that hasn't passed building inspection. I take pride in my work and my main priority is leaveing a job with the customer happy.

2 story extension front and back. Luke built the shell up for our 2 story extension, was very professional and knowledge, there was a few unforeseeable issues with the build that he came across which he was able to fix very easily, workmanship was extremely neat and pretty much everybody who has seen the work has commented on how neat it has been, our plasterer who came in afterwards has he's taken a lot of care not just inside but also on the finish inside as a lot of builders only care about outside and leave other to sort the inside out but luckily not luke, he also helped out massively when let down by other trades to help catch up and get ready for 1st fix trades, we also added in a lot of extras which weren't originally discussed but the work got carried out as usual to a very high standard at a very reasonable cost. They work very fast only really being held up by weather. I would definitely recommend Lh builders for any building work you need.
