On 5/13/2026 R Michael Flynn had this to say:
Great place to do business.. Was going to new windows, didn't need to. Dave replaced worn parts. All good now, saved a lot. Experience matters. AND they support our Veterans.

On 5/6/2026 Chad H had this to say:
Excellent experience, came out within a couple hours of contact. Had an egress window explode from the flood. Was given a price and timeline for new glass. Offered to cut a plexi glass temporary window to fill the hole until the new glass was ready. Came back within a couple of hours to install that. This was all done by Ray at Congress Glass. He has great customer service skills. An asset to the business. He finished the job today with the replacement glass that looks great. Highly recommended!

Congress Glass has exceptional service and workmanship! I've had them replace my screens last year and had them replace my patio screen recently due to hail damage. Their customer service is the best in the business! Testimonial written by Tom Lyke on this site.

On 4/2/2026 Anna Samson had this to say:
Worked with Congress Glass to get a shower door installed in the principal bathroom at our house. Amazing company to work with, from beginning to end. The process from getting measurements, to placing an order, and installing the door was much quicker than I anticipated. My husband and I are incredibly pleased with the results! I'd recommend Congress Glass to anyone needing this type of work done! 10/10 😎
