Simple job turned out to be not so simple. Turned up exactly when he said he would, did a good job, including taking on the extra degree of difficulty we had not foreseen. Job ran over from the single day expected, and returned the next day to finish off. Polite, efficient, punctual, and stuck to the price agreed.

Highly recommend Ben for plumbing and rendering work! He did a fantastic job — everything was completed to a high standard, on time, and within budget. Very honest, easy to communicate with, and offered practical solutions without upselling. His pricing was fair and transparent, and the quality of work speaks for itself. It’s rare to find someone so reliable and skilled these days — will definitely be using him again!

Stanley & his team originally came on board to build us a new rear extension which would house our kitchen as well as fit a new bathroom but as the project developed it ended up being near enough an entire house renovation and we're thrilled with the results. We still have work we would like to do to the outside of the house as well as a loft conversion and when we have enough money to take on those projects, we would definitely re-hire Stanley and his team. Highly recommend Stanley & his team.

STAY well away from this company. Quoted to fit stair carpet and stair rods. Arrived late and Ryan started to cut the stair rods. Ryan stayed for 3 hours then just walked out with no warning and never came back. I then found out that he cut 8 of the stair rods incorrectly. I advised him of this and he said he would replace. After not responding to my texts I can assume he is not replacing them which has now left me £88.00 out of pocket to replace. Be warned .
