Sliding windows open horizontally, with one or both sashes moving side to side along a track rather than up, down, or outward. They tend to suit wider-than-tall openings well and are a common fit for spaces like basements, hallways, and modern additions where a horizontal profile makes more sense than a vertical one.
Because there's no crank mechanism or vertical balance system, sliding windows are mechanically simple, which can mean fewer hardware parts to wear out over time. The tradeoff is a seal that relies on the sash pressing against the track and jamb rather than compressing the way a casement window does.
Sliding windows fit well in wide, horizontal openings and spaces where a simple, low-maintenance operation matters more than the tighter seal a casement window offers. They're also a practical choice where reaching up to a crank or pulling down a sash isn't convenient, since sliding side to side requires less reach.
One sash slides while the other stays fixed, a simple and common configuration for standard openings.
Both sashes move independently along the track, allowing either side to open and easier access for cleaning both panes.
Used in wider openings, typically with a fixed center panel and operable panels on one or both sides.
A common style for basement openings where a horizontal profile matches the available wall height better than a taller window style.
Additional lock points beyond the standard latch for ground-floor or basement sliders where extra security is a priority.
We measure the existing opening's width and height to confirm a sliding configuration fits well and identify the right panel arrangement.
You choose single-slide, double-slide, or a multi-panel arrangement based on the opening's proportions and your ventilation needs.
The old window is removed using the insert or full-frame method appropriate to the existing frame's condition.
The new sliding unit is set, leveled, and secured, with attention to a level track so the sash glides evenly.
We test the sliding action across the full track width and confirm the lock engages securely before finishing.
Insulation and exterior sealant are applied around the frame to close any gaps at the perimeter.
Sliding window pricing is influenced by panel count, frame material, and glass package, along with whether the installation is insert or full-frame. Multi-panel sliders and any added security hardware add to the scope. We provide a firm number after measuring your specific opening.
Get an EstimateA level track is the single most important detail on a sliding window installation, since a track that's even slightly out of level leads to a sash that binds or drifts open on its own. We take the time to get that right on every installation.
