   I couldn’t be happier with the work Onyx has done. This was my first building project and first time using tradespeople. I only had a rough sketch for two rooms with a high vaulted ceiling. Onyx took the sketch and delivered far more. Florin and his team completed the full job including soundproofing, flooring, plastering, decorating, electrics, doors and locks, plus several extra jobs that proved really helpful. Florin even suggested adding a storage mezzanine, which has made a huge difference. He is a true master who saw the full vision early, gave excellent advice on things I hadn’t considered, and flagged issues before they became problems. The team were always on time, tidy, considerate toward my neighbours and housemate living here during the job, and produced work to an extremely high standard. I’m over the moon with the result. The phrase “the right solution for you” was exactly right. Highly recommend Onyx to anyone.

   We have used Onyx for redecoration, refurbishment & maintenance works in our property, internally & externally. Florin & his team have produced quality workmanship & have always been polite & professional throughout. Some of the works were undertaken to a tight programme but deadlines were still met within time & budget. I would not hesitate to recommend this company.

   Thank you for doing such a fabulous job with our media wall. It turned out better than the photo we provided. We are absolutely chuffed with the way it looks and would absolutely recommend Onyx Builder Ltd. They provide an excellent service and quality of work is outstanding. Thank you for going the extra mile with the textured paint. We do love the final effect.
