The GJT Standard
We specialise in roof window installations for homeowners across Newry and County Down. As a VELUX Certified Installer with over 20 years of experience, we bring a level of knowledge and care to every job that generalist tradespeople simply cannot match.
Gary set up GJT Joinery after two decades working in joinery and roofing, driven by a straightforward belief: if a job is worth doing, it is worth doing properly. Every installation is treated with the same attention to detail, whether it is a single glazing replacement or a full new installation into a new opening.
