Vinyl windows can help protect your family and home in a storm. More importantly, purchasing vinyl windows will help to strengthen the integrity of your home. During a hurricane, impact windows are designed to remain intact even when cracked. Rather than glass shattering across the floor, impact windows will hold the shards of glass within the interlayer. We offer Vinyl windows from All American Window Company (AAWC), Jeld-Wen, PGT, Viwinco, and Sierra Pacific.

Our Customers

Brandi Sayers

Ours was a large project – 54 hurricane rated windows and 2 entrance ways . . . . The installation crew was considerate of our home and cleaned-up where they had been working each day.

Jan Burleigh

We would highly recommend Muhler! We had a window that was leaking and needed to be replaced. Muhler was the only company out of 5 I called that would do just an individual window.

Kenneth Robinson

Great job on window replacement. Muhler even help retrofit existing windows to match (went above and beyond to assure I was satisfied). Their customer service was excellent.
