Kevin Casey QS – UCC Student Hub

“I appointed Cozyglaze as the main company to carry out conservation and refurbishment work on the Cast iron windows on the Windel Building at UUC student hub and to design , fabricate ,double glaze and install new W20 Profile new windows and stainless steel windows I would highly recommend Cozyglaze I found them very competitive, standard of work top class and they delivered ahead of all dead lines , their  attention to detail was impeccable and I found Martin very professional and courteous at all times , I will definitely use them again”

Paul McGann – Dromore, Co Kerry

“After an extensive screening process I chose Cozy Glaze as best fit to restore my windows & doors. This was a big project with 84 windows & 16 external doors to be removed, restored, refinished & reinstalled. I have to say it was a great decision. Martin & his team were professional at all times. From the planning through to the finish they left nothing to chance & the results were exceptional. Any issues that arose were escalated and dealt with swiftly. They started & completed the work on schedule and the price was right. Martin & his crew were an absolute pleasure to deal with throughout the restoration & I highly recommend Martin Nolan and Cozy Glaze to anyone.”

Jason M., Cork

"Honestly, I didn’t think new glazing would make this much of a difference. CozyGlaze was recommended by a friend, and now I owe them a thank-you dinner. My place feels quieter, warmer, and just... better. Plus, the installation team was punctual, friendly, and cleaned up after themselves. Legends."

Emma L., Galway

"CozyGlaze completely transformed my home! I ordered their thermal glazing for my living room windows, and not only does it look sleek and modern, but the difference in warmth is unbelievable. My heating bill dropped, and my house actually feels like a cozy retreat now. The team was super professional and installation was a breeze. Highly recommend!"

Jim Osborne - Gorey Business Park

"Upgrading the windows across our business park with CozyGlaze was one of the smartest investments we’ve made. Not only have our tenants noticed a significant improvement in temperature regulation and noise reduction, but the sleek finish has given the entire park a more modern, professional look. The CozyGlaze team delivered on time, on budget, and with zero disruption to our tenants’ operations. Highly impressed."
