Took Nigel a while to call back to confirm a date and time a date and time for the work. Once he did though, he kept exactly to his word. Turned up, on time and completed the plastering for our stairway to a very high quality with patching and skimming work. The price was very fair and he finished in the time he said he would. We are very, very pleased with the finish.  Thanks again Nigel

They were very dodgy and unreliable. They took all the agreed money but never came back to finish the job. I was left without a kitchen, cooking utilises and drinking water for two whole months as no other builders were willing to pick up the mess they left behind. The garden was a complete mess with concrete and heavy building rumble. I strongly advise people to be wary of hiring them.

We were only planning to have new wooden double glazed windows for the front of the house, but were actually able to have new windows for the whole house. Alen also made suggestions which we had not thought about. He said we would have beautiful new windows and he has delivered. Clean, polite and kept informed throughout the process.

Shockingly bad. Given option 0f new skirting boards/existing ones. Stuart said old ones were fine, quoted to prep the walls, clear the glue off the old skirtings and do a really neat job. It was bad, he used four tubes of filler to fill gaps, no neat corking edge but smudged over the walls, corking over the floor, some skirtings fell off, I think he tried to use corking as glue. I gave him an opportunity to rectify before posting this rating, but he just made excuses. Chris
