Started off well then started disappearing off to other jobs (I am not local to the property) then carried out small painting touch up at another property. Tried to say he put 4 men into a terraced property, it’s just a days work for one person then tried to charge £1300!. Main job not completed and failed to turn up the Thursday because their car had been impounded as no insurance, refused to pay £1300 but asked for a fair price. They have now disappeared without completing what they have been paid to do

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.
