Extensions- 30 Jul 2019
Nathan from HCJ Building Service was excellent in all respects. He built an extension to our garage, which involved block-work, timber framing, roofing, cladding and installation of a door. When he visited the site to provide an estimate, he was enthusiastic and knowledgeable. His quote was competitive and he promptly answered a few questions we had about some of the technical details. When working on the project, he always arrived when he said he would and left the site tidy when he finished. My wife and I were impressed with how hard he worked, barely stopping to drink a coffee. When we interrupted him to find out how things were going he was happy to give us an update. He was always friendly and polite. He completed the project on time and left the site as he found it, removing all his waste. The work was done to a very high standard. We are really pleased with the result. This extension has freed up space in the garage for my woodworking hobby. We will definitely be coming back to Nathan to quote for future building projects. Now that I have my woodworking man cave my wife has started thinking about the kitchen...

Savage Bros built me a single storey extension on the back of house with pitched roof, four velux windows in a vaulted ceiling, they fitted a new cream gloss kitchen with black granite worktops and turned my old kitchen into a new dining room. Richard also installed a new bathroom suite and downstairs toilet and finished by tiling and painting the rooms. Richard takes great pride in his work and he has great attention to detail, I cannot fault anything. He comes in early and works solidly all day, cleaning up at the end of each day. A true professional in all aspects of the job. We would recommend him, he is a lovely genuine man.

Plastering- 7 Nov 2017
Bernie provides outstanding customer service. He takes great pride in his works and has a large understanding of skills that he is more than happy to share. He worked extremely well on leveling the fireplace to the correct height and the job was done in great timing. He had great availability for the job and I was so pleased that it was done urgently. He showed me some of his other works and it was a truly magnificent work of art to say the least and I would highly recommend him to friends and family.

Gavin and Luke built a single storey extension for us. It was quite complex and they had to remove several internal and external walls. They are very nice people to work with, genuine and honest, amenable. They were here for 9 months doing our work and we are thoroughly happy with them. They are very good - I would certainly recommend them.

Extensions- 8 Oct 2025
Jason and his team have just completed our wraparound extension, and the result has exceeded all expectations. Their workmanship, accuracy, and attention to detail are outstanding, and the whole process was smooth and stress-free. They stuck to timings, kept the budget in mind, and made everything feel effortless. Partway through the build, Jason had to undergo an operation and was signed off for five weeks. Remarkably, nothing was delayed — his team carried the project seamlessly, and with Jason still on site when he was able to be, everything ran perfectly. It’s a real credit to how capable they all are and the consistently high standards they work to. The only negative thing I can say is that we were sad to see them leave – they’ve been such a positive part of our daily lives over the past eight weeks. The finish is exceptional and we’re absolutely over the moon. We couldn’t recommend Jason and his team highly enough.
