sliding door replacement cost
An old sliding door gives itself away: it drags on the track, lets in a draft you can feel from the couch, fogs up between the panes, or leaves a damp sill after every storm. Whether the fix is a repair or a new door, the price depends on a handful of choices and on what is hiding under the old frame. Here are the prices Plum ProExteriors works from, what moves them, and a calculator that turns them into a range for your opening.

Installed, with removal, a new frame, flashing and project management, a gliding patio door runs from $8,860 to $10,950, standard to deluxe, and a French-style patio door from $13,860 to $15,950. Wood frames add $1,600, steel takes $400 off, and triple insulated glass adds $450. A rotted sill, a custom size or a new opening add work on top. A worn roller or a bad lock can often be repaired; foggy glass, drafts through the frame and a rotted sill usually mean replacement. Every project is quoted after we inspect the door and the opening.

Usually Worth Repairing
- Worn or broken rollers that make the door drag
- A dirty or pitted track, which can often be fixed with cleaning or a stainless track cap
- A broken handle or lock
- A torn screen or worn weatherstripping on a door that is otherwise sound
Usually Time to Replace
- Fog or condensation between the glass panes, which means the seal has failed
- Drafts through the frame, not just the weatherstripping
- A warped, cracked or rotting frame or sill
- A door 20 to 30 years old that was never insulated well to begin with
what drives the price of a patio door
Nine things change a patio door quote. Scroll through them, then compare any estimate you get against the list.
Frame material
Vinyl frames are the most economical and low maintenance. Fiberglass and composite frames are stronger and more stable through temperature swings. Wood and wood-clad frames give a warm interior look at the higher end. Aluminum frames are slim but conduct cold, which matters in a New England winter.
Size and number of panels
A standard two-panel door costs less than a wider opening, a three or four panel door, or a custom size. Older homes sometimes have non-standard openings that need a door built to fit.
Glass
Double-pane low-E glass is the baseline for comfort and efficiency. Triple-pane glass adds $450 per door; built-in blinds or decorative grilles each add to the price. Glass in a patio door is tempered safety glass by code.
Brand and features
Premium brands and features such as multi-point locks, better rollers and screen options cost more and generally last longer. We install Andersen patio doors among others, and standard, premium and deluxe in the calculator follow the series.
Panel or glass only
If the frame, sill and track are square and sound, sometimes only the moving panel or the glass needs replacing, which costs far less than a whole new door. This depends on the manufacturer still making the panel and on the frame being in good shape.
Insert or full-frame
An insert replacement fits a new door into the existing frame and is less work. A full-frame replacement removes everything down to the rough opening, which lets us repair the sill and flash the opening properly. In New England, where sliders often sit low and take snow and rain, full-frame is often the right call.
Sill and framing repair
Water that leaks past an old slider soaks the sill plate and subfloor. If they are rotted, they must be repaired before the new door goes in. We check for this before quoting.
A new opening
Cutting a new opening where there was no door, or widening an existing one, means structural framing, a new header and usually a permit. It costs much more than replacing a door in an existing opening.
Trim and finishing
Interior casing, exterior trim and paint are often needed after a full-frame replacement and should be in the quote.

Switching to a French or hinged patio door
Replacing a slider with a French-style patio door usually costs more, because hinged doors need more hardware and room to swing. In-swing doors need clear floor space inside; out-swing doors need clear space on the deck or patio. If the French door matches the existing opening, the swap is straightforward; if not, the header and framing need work. Our comparison of sliding vs French patio doors covers the trade-offs. The calculator above prices both styles.
How to Compare Quotes

frequently asked questions
How much does it cost to replace a sliding glass door?
Installed, a gliding patio door runs from $8,860 to $10,950 and a French-style patio door from $13,860 to $15,950, before sill repair or a size change. Use the calculator on this page, then book a free estimate for an exact quote.
How long does it take to replace a sliding glass door?
Most replacements take a day. Sill repair or a size change can add time.
Can I replace just the glass?
Sometimes. If the frame is sound and only the glass seal has failed, a glass replacement may be possible, but on older doors a full replacement is usually better value.
Is a vinyl sliding door good enough?
For many homes, yes. Fiberglass and wood-clad doors offer more strength and a richer look for a higher price.
Why does my sliding door feel so cold?
Older sliders often have aluminum frames, failed glass seals or worn weatherstripping. A new insulated door with low-E glass fixes all three.
What are the most common sliding door problems?
Dirty or damaged tracks, worn rollers, misaligned locks and failed glass seals that leave fog between the panes. The first three can usually be repaired; failed seals often mean replacement.
What is cheaper, French doors or a sliding door?
A sliding door. At our prices a gliding door starts at $8,860 and a French door at $13,860, because French doors use two operating panels and more hardware.
