Sliding Window Design Options

Sliding windows have a sleek, modern profile. Their broad horizontal shape can complement simple architectural styles and rooms with wide window openings.

Available colors, finishes, hardware, grilles, screens, glass options, configurations, and dimensions depend on the selected product and the existing opening. Applicable egress requirements may also affect which window fits a particular room. We can review all of these choices, then direct you toward the option(s) that make the most sense for your home and budget.

Broad Views, Natural Light & Ventilation

Our sliding windows use large panes of glass that increase the viewing area. Additionally, this can bring more daylight into kitchens, living rooms, family rooms, and other gathering spaces. Opening the moving sash also adds adjustable window ventilation without requiring clearance for an outward-projecting panel.

The best placement for your new windows depends on the size and shape of the existing opening, the room’s ventilation needs, and the amount of available wall space. Sliding windows are often considered for wide openings, but the exact fit and operating arrangement should be confirmed for the home rather than assumed from appearance alone.

Vinyl Frames & Everyday Maintenance

Vinyl frames offer a straightforward maintenance routine for busy homeowners. Unlike painted wood, vinyl doesn’t require recurring paint touch-ups and isn’t subject to rot. Routine care generally centers on keeping the glass, sash, frame, and track clean and checking that the lock and screen operate properly. These are just some of the reasons that we install virgin vinyl slider windows. 

What to Know About Our Industry-Leading Lifetime Warranty

Every sliding window we install is backed by our lifetime, non-prorated warranty. In addition to covering specified window components and operation, the warranty covers installation-related defects and installation labor. It also transfers to a new owner at no charge. That's not all. We provide free lifetime service labor for warranty service requests, along with 24-hour personal assistance for those requests.
