Bathroom Fitting- 7 Jul 2026
This guy don’t know what he doing. Didn’t know the job and no proper knowledge about the work. When he couldn’t do it sold us to another crook. The other person didn’t do work properly and left the bathroom unfunctional after three months. Very bad experience and they took more money when they buy materials. Its disaster

Bricklaying- 16 Dec 2021
I'm very pleased with the repair that Jack carried out on my garden wall. Even though it was a small job he took the time to do it properly and ensured the bricks that had fallen down were put back straight. It started raining a little on the day causing the cement to run. Jack returned a couple of days later to tidy it up like he said he would. On inspecting the wall today I noticed that the cement on the bricks on the inside of the wall did not look as neat as how it looks on the outside of the wall. Maybe the rain caused the cement to run too much, I don't know. Overall I am pleased though and I've asked Jack to quote for another job.
