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

Extensions- 8 Nov 2024
After much deliberation, I picked Daron and his crew for our job. From start he was very flexible, honest and accommodating. We quickly understood each other. His crew showed up when agreed and hit the ground running. The shell for our side extension was up in 4 weeks, quicker than expected. Quality of work was really good. As I am now taking over to finish the job, I also really appreciated that both Daron and his guys were more than happy to discuss next steps, or how to do some of the things. Also, if I get stuck I know I will be able to give them a ring and get them booked in to complete some of the items. It was a real pleasure working with them all, and should I have another job come up, I will not hesitate to call them again.
