The bathroom looks brilliant couldn’t be happier, more than happy to trust them when not at the property and to top it all off when they were finished I went out to my garage so that I could take all of the rubbish to the tip and they had beat me to it.

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.

Hired paul to reconfigure my kitchen. He did not complete the job and walked out after 3 weeks leaving numerous jobs unfinished. Many things they did have had to be redone, the finish was shoddy and I don't think he knows what a right angle is. Would obviously not recommend, other tradesmen that have seen his workmanship have told me to report him to trading standards. He left me with a half finished job, saying he was not able to achieve the level of finish I was looking for.
