Sliding Replacement Windows in Pittsburgh

Sliding windows have one or two sashes that glide sideways along a track instead of lifting up and down. They are simple to operate, give you a wide unobstructed view and fit openings that are wider than they are tall. For kitchens, family rooms, bedrooms and ranch homes with long horizontal openings, a slider is often the most practical choice.

Our published range for quality vinyl double hung windows is $450 to $1,200 per window installed. Sliding windows, especially large or custom sizes, cost more than that standard range, and we price them at your free in home quote so the number reflects your exact openings, glass and trim.

How Sliding Windows Work

A standard slider has one fixed panel and one operating panel that rolls along a track at the sill. Some models have two operating panels, and a three panel slider uses a fixed center with operating sashes on each end. There are no cranks, balances or hinges to wear out, so a quality sliding window is one of the simplest windows to live with. Most operating sashes lift out of the track for easy cleaning.

Where Sliding Windows Make Sense

• Wide openings. If an opening is wider than it is tall, a slider uses the space naturally, while a double hung in the same spot would need to be split into two units.
• Ranch and split level homes. Many homes built in the middle of the last century have long, low openings designed for sliders.
• Over counters and furniture. Sliding a sash sideways takes less effort than lifting one, which helps when you are reaching over a counter or dresser.
• Next to decks and walkways. Unlike a casement window, a slider never swings out into the space outside.
• Basements. Small sliders are common in basement openings. See our basement and egress windows page.

If you prefer a more traditional look, a double hung window may suit the house better. We are happy to show both at your quote.

Sliding Window vs Sliding Patio Door

Sliding windows and sliding patio doors work on the same principle but serve different jobs. Many homeowners replace both at the same time so the frames, color and glass match across the back of the house. We can schedule both in one project.

Energy Efficiency

Older sliders often leak air along the meeting rail and at the bottom track, and their tracks can fill with debris that keeps the sash from closing tight. A new sliding window with good weatherstripping, an interlocking meeting rail, a positive lock and double or triple pane low E glass performs far better. As with every window, installation matters. We level the frame so the sash rolls smoothly and closes fully, insulate and seal the gap, and flash the exterior. To compare energy labels between quotes, read our guide to U factor and SHGC.

Signs Your Sliding Windows Need Replacing

• The sash sticks, jumps the track or takes two hands to move.
• You feel a draft along the middle where the panels meet.
• The lock will not line up or latch.
• Fog or moisture appears between the panes.
• The frame is cracked, warped or rotted.

Any one of these on its own may be fixable with a new roller or a cleaned track. When several show up together, or the frame itself is damaged, replacement usually costs less over time than chasing repairs, and you gain a quieter, warmer room in the process. We will tell you honestly which situation you are in when we look at the window.

Cost of Sliding Window Replacement

Price depends on the width and height of the opening, the number of panels, the glass package, the frame material and whether we do an insert or full frame install. Sliders are priced at your free in home quote, and very wide or custom units cost more than standard sizes. We give you an exact written price at a free in home quote, and the window price estimator can give you a starting range for the whole house.

Our Installation

We measure every opening for a custom window, remove the old unit, inspect the frame and sill, and choose insert or full frame replacement based on what we find. Each opening typically takes 30 to 60 minutes. Outside, we flash the opening and cap the wood trim with aluminum or vinyl so it never needs paint. Learn more on our main window replacement page.

Frequently Asked Questions

Are sliding windows energy efficient?

A modern sliding window with good weatherstripping, an interlocking meeting rail, a positive lock and double or triple pane low E glass performs well, especially when it is leveled, sealed and flashed correctly.

How much do sliding replacement windows cost?

Sliders are priced at your free in home quote based on size and options. For reference, our quality vinyl double hung windows run $450 to $1,200 per window installed. Very wide or custom sliders cost more and are priced at a free quote.

Is a slider or a double hung better?

Sliders fit wide, short openings and are easy to operate over counters. Double hung windows suit taller openings and traditional homes. We recommend the right style for each opening at your quote.

Why is my sliding window hard to open?

Common causes are a worn roller, a dirty or damaged track, or a frame that has shifted out of level. If cleaning the track does not help, the window may be due for replacement.

Can you replace sliding windows and a patio door together?

Yes. Many homeowners replace sliders and a sliding patio door in one project so the frames, color and glass match.
