Rep Randy was fantastic! He was professional, knowledgeable and accommodating. He explained my options and provided detailed information; he helped with my window upgrade plan that was completed in 2 phases (fall 2025 & spring 2026)
The install team of Scott, Dave, and Deana was impressive. They are definitely experts in their field - efficient with the install process and very capable dealing with heights and difficult window locations. I appreciate they did a thorough cleanup after each job.
Lia the painter was meticulous with final touch ups.
Rob was great. He monitored the difficult installs, and completed follow-ups and final inspections.
One issue encountered was a manufacturer’s factory defect in one large window. A replacement order was promptly processed (through warranty) and a new glass pane was installed a couple months later in June 2026.
My new windows have created an updated and amazing new look to my home.
Nagy Bros provided outstanding customer service, a quality product, and exceptional results.
I Highly recommend the Nagy Bros team.

They were also very approachable and answered any and all questions ( I had many) with clear and responsive communication. I highly recommend Nagy.
Rob was great with following up to make sure all the final tasks were complete.
I’d highly recommend Nagy Bros to anyone considering a window project — they made the whole process smooth and enjoyable.
