Extensions- 31 Oct 2019
Sam built a 9 meter by 4 meter ground floor extension for us, it has 2 rooms, 2 large sky lights, french doors and a patio. The build came in on time and on budget, Sam and his guys where always friendly and courteous, would explain what was going on and made sure we where happy with everything. We have autistic boys, one of them likes to know whats happening at all times and wanted to help and ask question non stop, the guys where absolutely brilliant with them, even letting them lay some bricks. I could not have asked for better workman when it came to my boys! We are very happy with our extension, it has made a massive difference to our home and lives. We have no problem at all in highly recommending Sam to anyone!! Shel & Jim Aitken

Conversions - General- 21 Mar 2026
Arturas and his team have done an outstanding job in a complex, full-flat renovation involving structural work, floor levelling, complete electrical rewire, complete re-plumbing including pumps and heater, full bathroom and kitchen fitting, basically everything. I honestly could not have hired a better builder. Quality: the team is exceptionally dedicated and diligent, following the design to the millimetre, reading every specification and installation instruction, being exceedingly careful to ensure everything is done at a high standard. The result speaks for itself - everyone who visited the flat is in awe about the quality of workmanship. Expertise: the team really knows what they are doing. There was nothing they can’t handle, and they found very smart solutions to every problem. They advised me at every step of the way, with patience and clarity. Honesty: Arturas, Vasyl and Vova are excellent people, honest to the bone, trustworthy and principled. In summary, top class builders.

Restoration & Refurbishment- 2 Apr 2026
Really pleased I chose Leigh Matthews for this job. We were taking over a building that was unoccupied for 18 months and there were some issues with that, The team were excellent, and they finished the 4-week job on time, and right on budget. They were helpful and considerate and left the premises clean and tidy. They were also able to help out with some problems with the plumbing that were not in the original scope. I loved the way they did the estimate and the invoicing. Breaking all the items down into the individual tasks and at the end of each week, itemising which tasks were complete and a %age on those in progress. I would not hesitate to employ them again

Groundwork & Foundations- 22 May 2026
John did a fantastic job with the groundworks for our new 150sqm block driveway. He priced keenly, started quickly and was on-site consistently every day for the week. Really skilled with the digger, good at dealing with the neighbours and always fun to talk to. Some aspects of the job changed based on what the dig uncovered, but he was pragmatic and ultimately left me feeling that he just really wanted to do a good job as if it was his own. Highly recommended - 10/10.

Sean did a full refurbishment on our house. He is the most organised and customer friendly builder I have ever used. From start to finish there was a plan of action and then a great group of qualified tradesman to execute. Like every refurbishment, we asked for changes and he always made us feel like the extras were no problem. I have no hesitation in recommending CG Carpentry. They are now our go to builders and in our next move he will be the first person I call.

Groundwork & Foundations- 27 May 2026
Rich was v knowledgeable and priced the job from photo's and a video. Kept his word and turned up on the agreed day. He got to work straight away, broke up the original pipework and installed a new set of plastic pipes. He created a new connection for a vertical stack and improved what was there. Rich was finished within 2 days and drains are definitely working better since he did the work. I would like him to come back and finish the stack. I thoroughly recommend Rich if you're looking for a reliable and competent builder.
