Mr Jackson built a large 5000 sq ft house for me his workmanship was excellent, very professional, trustworthy, ultra reliable and very honest. Did a great job and I would have no hesitation in recommending him. He is an excellent tradesman with a good knowledge of not only his own trade but also most of all the other trades associated with the building industry as he assisted me with several issues unrelated to his own work. I thank him for the work he did for me and wish him well with any other projects he under takes.

Carpentry- 23 Aug 2025
I asked PC joinery to fix a water damaged bathroom floor, and I was really impressed. Even though it was a smaller project, they gave it the same care and attention you’d expect on a big one. They arrived on time, worked efficiently, and the finish was perfect. Friendly, professional, and tidy — exactly what you want from a tradesperson. I’ll definitely be using them again and would highly recommend them to anyone needing quality joinery work, big or small.
