What our Windows are all about

Upgrade Your Home's Efficiency and Curb Appeal

Energy-efficient windows let you enjoy the outdoors without compromising your indoor comfort. New windows improve your view and give you better control over ventilation and security—and our experts can give you thousands of ways to do so. A single window can have over 50,000 combinations of options to choose from, so let a Weather Tight expert walk you through details of each feature and find a custom fit for your home. Vinyl window replacements are our specialty—it's how we got our start back in 1986.

Restorations® Windows Come With Variety and Versatility

Patented window design options from Restorations allow you to create the window you want—there's nothing else like these on the market. Choose from Double hung or Full frame options that enlarge your view by up to 30 percent, and select from over 18 different color combinations and wood grains. With the right design, a single window can really open and update a room. — Read more

If you're looking for a window that adds depth and aesthetic interest to your home, consider a Bow or bay window. These windows offer stunning panoramic views and create the illusion of a larger room. Choose between curved or angled, double hung or casement, and in a variety of color options that enhance any home.

Garden windows are named after their greenhouse-like qualities, offering four sides that invite light and fresh air inside. Hinged panes can open toward or away from the house as needed, and create a perfect place for indoor plants or enjoying outside scenes.

Attractive Windows That Work Hard to Save You Money

For the best in energy efficiency, Sliding and Casement windows feature triple-pane glass and have the best air infiltration ratings on the market. Casement windows open a full 90 degrees for ideal ventilation, and have a multi-point locking system with heavy-duty hardware for improved security. Similarly, sliding windows give you the option of two or three sliding panes, adaptable according to outdoor temps. Homeowners love these windows for their customization options, larger viewing areas, and advanced efficiency. — Read more
