Patio Door Installation Cost Calculator

What affects the price of a patio door install

A patio door replacement in an existing opening is a same-day job for one crew. Cutting a new opening or upgrading to French doors is a different animal. Four levers do most of the work.

Door type. Sliding vinyl doors are the cheapest — mass-produced, lightweight, and easy for one crew to lift into place. Sliding fiberglass doors are more rigid, hold their color longer in the sun, and cost 40% to 60% more than vinyl. French doors are the priciest because there are twice as many panels, twice as much hardware, and tighter tolerances required.

Frame condition. Removing an existing door in a sound frame is a half-day job. If the sill is rotten or the framing behind the trim is soft, add half a day of carpentry.

New opening or same opening. A like-for-like swap in an existing opening is the cheapest install. Enlarging the opening or cutting a new one means header work, drywall or siding patching, and interior finish. That adds one to two days and $500 to $2,500.

Region. Labor is 25% to 40% of the total and swings with local rates. The state selector applies a multiplier to the whole estimate.

Installed cost per door for a like-for-like replacement in an existing opening.

Cost by number of doors

Total installed price by quantity, using a sliding vinyl door as the baseline. The calculator adjusts for door type and state.

What is included in these estimates

The ranges cover a same-opening replacement by a certified installer. Included:

• New door unit: frame, panels, tracks, hardware and screen.
• Removal and disposal of the existing door.
• Weatherproofing: flashing tape, sealant, foam insulation around the frame.
• Interior and exterior trim to match the existing opening.
• Basic hardware installation and a first-round adjustment.
• Cleanup and haul-off of the old door.

Not included, add separately:

• Enlarging the opening or cutting a new one. Budget $500 to $2,500 depending on wall type and finish.
• Interior finish work: drywall patch, paint, flooring transitions.
• Exterior finish: siding patch, brick repair, stucco touch-up.
• Blinds, shades or motorized coverings.
• Smart locks, security sensors or auto-close hardware.
• Rotted sill or framing repair discovered during removal.

Energy efficiency, NFRC labels and tax credits

A patio door is a large hole in the wall. Getting the energy specs right saves money for as long as you own the house and can qualify for a federal tax credit today.

U-factor. How much heat passes through the door. Lower is better. ENERGY STAR ranges from 0.24 in the Northern zone to 0.40 in the Southern zone. A basic builder-grade sliding door often measures 0.60 — nearly double the heat loss of a certified door.

Solar heat gain coefficient (SHGC). How much of the sun's heat passes through the glass. In hot climates, lower is better (0.25 or under). In cold climates a higher SHGC on a south-facing door is a free winter heat source.

Air leakage. Certified doors test at 0.3 cubic feet per minute per square foot or lower. Cheap doors can leak 3× that. On a sliding door the biggest leak path is the meeting stile between the two panels — inspect the weatherstrip when comparing brands.

Federal tax credit. The 2026 Energy Efficient Home Improvement Credit covers 30% of the door cost, capped at $250 per door and $500 total per year for exterior doors. The door must be ENERGY STAR certified for your climate zone. Save the manufacturer's certification statement — the IRS may ask.

State and utility rebates. Roughly 20 states or their utilities offer rebates for high-efficiency doors, typically $50 to $200 per door. Check the DSIRE database or ask the installer.

How to read an NFRC label. Every legitimate door has a National Fenestration Rating Council label on it. The label shows U-factor, SHGC, visible transmittance and air leakage. Without an NFRC label the manufacturer's efficiency claims are unverified.

When it makes sense to DIY

A patio door install is at the edge of what a confident DIYer can do, because a single mistake can leak for years before you notice. Rules of thumb:

• Like-for-like sliding replacement, same opening, ground floor: borderline. A vinyl slider weighs 150 to 250 pounds and needs two people to lift into place. Sealing and flashing must be done right the first time.
• French door replacement: hire a pro. The double-panel alignment is unforgiving and the astragal (the vertical seal between the panels) is easy to install wrong.
• New opening or upsizing: hire a pro. Header sizing for a load-bearing wall is a life-safety issue, not a DIY shortcut.
• Upstairs or second-story doors: hire a pro. Lifting a door up a ladder or through a window is a two-serious-injury project.

DIY savings on a like-for-like vinyl slider are $500 to $1,000 — about 30% to 40% of the installed cost. If a leak develops later, that savings evaporates on the first drywall repair. Most homeowners find the certainty of a professional install worth the premium.
