Sliding doors: the default tier ($1,500-$3,500 installed)

The two-panel slider is the most common patio door for a reason: it needs no swing clearance, uses a simple track-and-roller mechanism, and prices the category's floor. Homewyse's May 2026 calculator puts a basic national replacement at $997 to $1,526 per door -- unit plus labor in a standard opening -- while HomeGuide prices sliding glass doors $1,200 to $4,000 installed, averaging around $2,565 (HomeAdvisor).

The spread is size and glazing: a standard 6-foot vinyl two-panel slider with double-pane glass prices the low side, while larger multi-panel sliders, fiberglass frames, and Low-E or triple-pane glass drive the top. The track is the maintenance line -- debris buildup and roller wear are the two most common service issues -- but the mechanism stays simple -- which is what keeps sliders on the budget tier.

French doors: the classic tier ($1,500-$5,500 installed)

Exterior French doors price $1,300 to $5,500 installed in HomeGuide's 2026 data, with multiple sources converging near $1,500 to $5,000 for a standard pair -- the door units themselves $300 to $2,000, labor another $300 to $1,500. Hinged French doors need swing clearance on one side, and hardware, framing, and finishing stack on top of the unit price. Aluminum French doors price a premium tier for slim sightlines and salt-air durability.

The French premium over a comparable slider is real but narrow: French doors cost somewhat more than an equivalent slider and need swing space, while using the same rough opening -- which keeps structural costs down when switching between the two. Thumbtack's 2026 data shows labor-focused installs $490 to $1,392, reaching $2,987 at the complex end: existing openings low side, new openings high.

Bi-fold doors: the premium tier ($5,000-$20,000 installed)

Bi-fold and multi-panel systems are the premium tier: $5,000 to $20,000 installed in HomeGuide's 2026 figures, $5,000 to $11,000+ in HomeStars data. The money buys the full opening -- folding panels that stack away and erase the wall line. Every panel adds unit cost, and wider openings can trigger header reinforcement before the first panel arrives.

Bi-fold labor prices the specialist tier: alignment and sealing across multiple folding panels punishes sloppy installation, and the hardware -- tracks, hinges, rollers at every joint -- is the ongoing maintenance line. The value case is the opening itself -- the full-width connection between interior and patio. Where the budget allows, bi-folds are the statement choice.

The four lines: unit, labor, disposal, add-ons

Every quote is four lines. The unit line prices $300 to $3,000+ depending on style, size, frame material, and glazing. The labor line prices $200 to $1,000 for a standard replacement in 2026 data -- new openings, structural work, and multi-panel systems multiply it. The disposal line -- hauling away the old door and construction debris -- prices $100 to $500.

The add-on line stacks on top: screen doors, insulation upgrades, and security locks are usually quoted separately. Moving past a standard 6-foot opening can trigger header reinforcement -- a few hundred dollars before any other upgrade. Price all four lines before comparing quotes, or the low bid hides its add-ons in the fine print.

The Orange County angle: labor, salt air, permits

Orange County prices the high side of every band: coastal labor markets carry demand premiums, and skilled door installers price above band mids. New openings and structural changes trigger permits plus inspection scheduling that stretches the calendar

Salt air is the OC-specific material line: it punishes iron hardware and rewards aluminum and stainless steel -- a real consideration for French and bi-fold hardware. Frame material drives long-term cost as much as upfront price: vinyl insulates well for less, while aluminum and wood-clad cost more but hold up better in the coastal climate.

DIY vs. hiring a pro

The owner-done lanes are the maintenance lanes: track cleaning, roller swaps, weatherstripping, and screen replacement on a sound slider. A full unit swap -- even same-size -- is the pro lane: heavy glass, alignment, water-intrusion risk. New openings are the never-owner lane: header reinforcement, framing, and permits filed before work starts.
