Homeowners love folding (bi-fold or accordion) doors for their ability to open living areas to patios, pool decks, and spectacular views. Yet the price tag can vary widely. Understanding exactly what drives folding door installation cost is the first step toward a smart, budget-friendly build. CountBricks combines real-time material databases, voice-powered estimating, and blueprint takeoffs to give you clarity before the first panel is unboxed.
• Standard two-panel interior sets start around 60" wide, while exterior stacking systems can span 24' or more. Every added panel means more glass, hardware, and structural preparation.
• Odd sizes or custom heights increase fabrication complexity and freight charges.
• Vinyl and aluminum frames remain economical for most residential builds.
• Thermally broken aluminum and clad-wood hybrids raise energy performance but add 25-40 % to material cost.
• Solid wood frames deliver a premium architectural look and the highest price point.
• Single-pane interior units are inexpensive but rarely used on exteriors.
• Dual-pane low-E glass is the residential standard and balances efficiency with cost.
• Triple-pane, impact-rated, or tinted glass upgrades can raise material totals by 15-30 %.
• Basic top-hung tracks work for small openings.
• Heavy-duty stainless or marine-grade tracks, multi-point locks, and flush thresholds add durability—and expense—in coastal climates.
• Removing existing walls, rerouting electrical, or adding headers for wide spans affects labor hours.
• Second-story installations require more manpower and safety gear.
• Urban sites may have delivery restrictions that increase handling time.
Based on thousands of CountBricks residential projects nationwide, the typical turnkey price falls between $950 and $1,450 per linear foot. That total includes:
• Door panels and frame
• Glass and glazing
• Hardware, tracks, and seals
• Carpentry and finish work
• Jobsite protection and cleanup
Actual figures shift with region, season, and product choice, but these benchmarks help homeowners check quotes for realism before committing.

• Plan electrical reroutes early; change-orders for hidden wiring can inflate costs by 10 %.
• Schedule installation during shoulder seasons when trade schedules are flexible—labor rates often dip 5-8 %.
• Coastal exposure demands stainless hardware and impact glass to combat salt and wind pressures.
• Passive house or net-zero builds justify triple glazing and insulated frames for long-term energy payback.
• Barrier-free living spaces may require recessed tracks and flush sills that eliminate tripping hazards.

When the Rivera family planned to replace a 10' sliding door with a panoramic folding system, they turned to CountBricks for clarity. Salt-spray conditions and strict energy codes made local pricing unpredictable.
1. The homeowner walked the space with a smartphone, dictating dimensions and noting the existing header size.
2. CountBricks AI instantly detected that a new LVL header would be required to handle the wider opening.
• Four-panel thermally broken aluminum door: $8,250
• Impact-rated low-E glass upgrade: $1,400
• Stainless hardware package: $780
• Structural, carpentry, finish labor: $2,600
Total projected cost: $13,030
• CountBricks pre-scheduled delivery and crane lift, avoiding street-closure fees common in the area.
• On-site adjustments were captured in the mobile app, updating the invoice before changes became disputes.
• Final inspection showed ≤1 mm deflection on the header and perfect threshold drainage, winning county approval on the first pass.
• Order glass a half-shade darker in west-facing rooms to cut glare without resorting to blinds.
