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!

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.

Absolutely fantastic service. We had cracks in our two main bedrooms, hallways and living room that needed repairing whilst we were living in the house with a baby and small child. Tilly got three men on the job to get it all completed asap. The team worked flat out without breaks and got done in 2.5 days (Tilly quoted aprox 3 days). They did over and above what I’d asked them to painting areas they hadn’t even replastered to make the hose look fresh. Tilly quoted & charged very reasonably too.

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.
