5-star reviews

“Well, it’s been 6 weeks since we had our new windows installed by Guardian Windows Team. And from estimate to installation to the comfort of living with 29 new windows, we could not be happier. Matt, Andre, and Darrell rocked the installation in 3.5 days. These guys showed up when they said they would, worked until they were ata good stopping point, cleaned up the work site each day, and were extremely considerate of the inside of the house and the outside flower beds. We have had a lot of workers in the house over past severeal years with various remodeling projects, and this crew was the best! The new windows are beautiful, reduce outside noise significantly, and are highly efficient compared to our old builder-grade-ugly-19-year-old windows. For the same 30-day period (June 15 – July 14) in 2022 (avarage temp high.low = 97/74) we used 2996 kWh. For 2023 (avarage temp high/low = 99/78) we used 2555kWh. So even with it being one of the hotter months to recode, we still used 16% less electricity. If you are in the market for new windows and want a high-quality product from a local company, give Martin Scarpati and his team at Guardian Windows a chance to earn your business.”
