⸻ I hired GJ Builder to build a new garden step, and I’m very pleased with the outcome. They were punctual, professional and paid close attention to detail. The step is solid, well aligned, and blends beautifully with the garden’s style. Communication was clear throughout, and they cleaned up thoroughly after the work was done. I highly recommend them for anyone needing high-quality brickwork.Verified reviewerJob location: CR4
