Landscaping- 12 Jan 2021
Brady and the lads did a fantastic job building me a fully insulated rendered block garden room. I went for Ellis Phillip because both Brady and Andrew are genuinely decent and trustworthy guys. They were tidy from the onset and even covered my whole driveway in a layer of board and plastic sheet before the job started to prevent and damage and mess. Good quality of work and finish. Brady uses the same teams (eg plasterers, electrician, etc) for his jobs and they all work well together and communicate all aspects of the job with each other which helps alot. Nothing was too much trouble - we made numerous last minute changes throughout the job and he was happy to accommodate them. Job finished in a decent time scale. We're extremely pleased with the finished result and would definitely use again and recommend to friends and family.

Carpentry- 20 Apr 2026
I recently had my 5 doors supplied and fitted, and a staircase with handrail built by this carpenter, and I’m genuinely very impressed with the work. The quality of the finish is excellent — everything looks neat, solid, and very beautiful. The staircase in particular has completely transformed the space. He was professional throughout and, importantly, stuck to the agreed timeline, which I really appreciated. The whole process was smooth and stress-free. I’d definitely recommend him to anyone looking for reliable and skilled carpentry work.
