Bricklaying- 20 Feb 2020
Our job was a completion of a front wall that had been damaged. Matthew understood our wall design helped with a decision for space for a gate. Visited a couple of times with brick types to ensure we liked the finished look. Job was completed in time frame suggested and if any changes in days it was communicated. Very professional, great price, tidy and polite. Very pleased with work. Would definitely recommend.

Plumbing- 15 Nov 2025
Incompetent company. They were contracted to put a new shower cubicle in one bathroom and regrout and make good and regrout in another bathroom. This company are completely incompetent. We had to take out all of the grouting that they did as it was so poor and all of the sealant. It was clear that they had no experience of fitting bathrooms or tiling at all. They did not even seal the sides of the shower unit against the walls, so water would be able to run right out of the shower cubicle. They did not connect the waste pipe and water came straight through the ceiling. I would not recommend this company to do any work.
