Refurbishment and all building work

Latest homeowner review

Reviewed by alexa on 28/3/2026

I couldn’t be happier with the work done on our partition wall! From start to finish, he was reliable, professional, and clearly takes pride in what he does. He treated our home with respect, kept everything tidy, and communicated well throughout the process. The finished result is exactly what we asked for—neat, solid, and completed to a really high standard. It’s not always easy to find someone you can fully trust with work in your home, but he absolutely delivered. I genuinely cannot recommend him high

I recently had some render work done on my house by Spraytex, and I couldn't be happier with the results! The quality of the work is outstanding, and it has truly transformed the look of my home. Debbie & Siobhan provided good customer service throughout the entire process, answering any questions I had. Additionally, the work area was left very tidy after each day, which I really appreciated. I highly recommend Spraytex and Gaz (Installer) for any rendering needs!

Whilst fairly pleased with the work, the renderer (Anatoly), did not place scaffold back into existing location. A scaffold ladder was left hanging by a single clip. Bars and boards not returned closer to the building leaving huge gaps. Red brick dust has stained 4 days after completion. The disgraceful condition of the scaffold is gross in my opinion

Cannot rate this company highly enough; they were brilliant. The quality of the work was great; they took pride in what they did. They came and quoted, and provided a clear statement of work on what we agreed. They completed the work quickly. Turned up when they said they would, and if they couldn't, they let me know. Really good communication. They were so polite, courteous, and just generally really nice people to have in your house.
