Driveways (Paved & Loose)- 24 Apr 2026
I highly recommend JJ Brick and Stonework, it's a breath of fresh air having a team turn up to work first thing in morning and putting in full days work. No job was too much trouble and they went above and beyond and did little jobs that cropped up along the way too. I would have no hesitation in calling Joe and his team in the future. Thank you.

Jason came quickly after speaking over the phone, after the leak got worse he got the scaffolding up quicker than we originally agreed. He didn't ask for a deposit and kept me updated throughout, cleaned up before he left. Would highly recommend.

Extensions- 4 Jan 2020
On budget. On schedule. Resulting in a stunning kitchen extension built by two delightful, highly skilled, creative, flexible, resourceful craftsmen who were open to incorporating ideas as they worked. We were impressed from the outset by the extremely detailed quote that was presented to us by Richard and Ian which included a complete breakdown of all materials and labour, almost to every nail and screw. It gave us the confidence to know there would be no nasty surprises along the way. Working to our plans, they dealt with any obstacles that they encountered during the build by suggesting clever, practical solutions, always mindful of our vision. Work began on the agreed day and both Richard and Ian came every day without fail until completion. We could tell from the outset that they took immense pride in their work and constantly checked that we were happy with the quality and progress. For such a large extension, they managed to keep disruption to an absolute minimum and impressed everyone with an incredibly clean and tidy site. We are thrilled with our new space and everyone loves it. We cannot thank Richard and Ian enough for their hard work and professionalism. We actually enjoyed the experience and really missed them when the work was completed, they became part of our family! We cannot recommend them more highly and consider ourselves very fortunate to have found them.

Driveways (Paved & Loose)- 16 Apr 2025
Amazing work by Adam to give us not only a large block paved driveway but also a resin surface down the side of the house, a new patio as well as a rubber crumb play area for the kids. Clear communication, attention to detail and a reasonable quote for the amount of work required. Couldn't have asked for more really. Highly recommended.
