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!

I'd highly recommend Alan and Kieron from ADK Building. They installed our bathroom to a very high standard from the plumbing through to tiling, installing underfloor heating and constructing custom made shelving to overcome a challenging job. Alan is very friendly, helpful and polite, he discussed the requirements in detail and any unforeseen problems were explained and dealt with. The work area was left clean and tidy each day.

Following some work done successfully in 2022 by this company, I reached out to have some similar work done in 2024. However, I paid a deposit for the work, the job was never started, communication stopped, despite me reaching out via phone and email, and I never received my deposit back. Highly disappointing after a great experience the first time round. I would not recommend.
