Starmark Evo composite windows deliver unmatched durability and aesthetic appeal, mimicking wood's elegance without maintenance demands. Their advanced polymeric frames resist warping and fading, ideal for extreme weather.

Sliding Patio Doors
OKNA sliding patio doors provide seamless indoor-outdoor living with superior thermal performance and security. Featuring thermally welded frames and double weather-stripping, they prevent air leaks and noise intrusion. Customizable sizes and finishes allow tailored integration with your home's architecture for both functionality and aesthetic appeal.

Custom-fabricated seamless gutters eliminate leaks through continuous metal construction, protecting homes from water damage. Installed with precision to match roof dimensions, these systems include optional gutter guards to prevent debris buildup.

Excellent service! Email for estimates returned in very timely manner. Chris, who did estimate, showed up when I was told he would almost to the minute. Angie was very pleasant and professional with the arrangements of the estimate and installation appointment. The guys that installed, Allan, Joe and mike were knowledgeable and skilled at the trade. We did 12 windows and they were installed in 4 hours. They cleaned up after themselves. We are very pleased with the whole experience!

We were more than pleased with Window Works! They came out 9 days ahead of schedule because the rain caused them to lose work through the week. They were on time and working as soon as they arrived! Excellent job on our windows and very friendly service!

Window works replaced 11 windows at our home today! The final product was beautiful and the installers, Allan and Mikey were very nice and did a terrific job! I would highly recommend Window Works and would request Allan and Mikey again!
