Cory and Jon made floor to ceiling bedroom wardrobes out of mdf for me to paint. I am satisfied with their work. They both worked very hard and I had no issue with giving them my house keys to get on with the job whilst I was at work. They were very trustworthy. They were very reliable though the job did take longer than anticipated.

Not very happy. The company (Paul) didnt finish the job and I had to pay out more than I had withheld (£50) to another tradesman to complete the job. The work that was completed was satisfactory but in view of the job not being finished cannot rate them well. Also never got my keys back despite numerous pleas. Not reliable at all.

Reviewed by JULIA on 16/9/2020

They turned up without any materials and we had difficulty getting any. The fence has been put up in a bad way with short posts, and screws dangerously protruding through to next door. My old patio was not taken up as quoted, and new slabs were laid over the top. It is not level and slopes forward & sideways with a bump in the middle. Slabs are uneven, the built step has all broken away, as there is little support under it. And the grouting has gaps and different grouts used. Too many other probs to list.

This tradesman's? standard of work is appalling & I can only assume his Rated People reviews are false. We had no option but to dismiss him after he ruined our lounge. The numerous faults eg. large gaps above bay window, uneven walls, plastering abysmal. His cleaning up was non-existent & left my home in a disgraceful mess, cement and plaster covering our wooden floor & doors. We had to hack off all his work and start again! This has cost us dearly, not to mention the stress. RATED PEOPLE? I DONT THINK SO!

Use at your own risk. Did good job on garden wall even had comments from passersby say how good it was. Phil even got jobs from local builder based on what he did when they saw it. But as for the rest of the work laying the patio in the garden he quoted £1200 for I expected a first class job considering the actual concrete only cost £305. But he subcontracted it out to someone who did a worse job then I could have done myself. I have been in contact with the person who did it but hasn't sorted.
