Plastering- 1 Jun 2026
I hired Joel to render and plaster some indoor walls for my Terrace house renovation. He was professional in his visits, and his work was excellent. He also left the workplace as clean as he found it. It was a pleasure to work with Joel, and I shall certainly be using him again. I have no hesitation in providing a good review for him. Gareth.
