Bi fold door fitting costs include the door kit, frame, labor, and any necessary trim or adjustments. This guide shows typical price ranges for common setups and the main drivers behind the price, with practical per-unit and total estimates.
Introduction note: The keyword cost or price appears in the first 100 words to reflect buyers’ budgeting needs for bi fold doors and the primary cost drivers such as door type, hardware, site prep, and labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door kit (bi-fold, 2 doors) | $600 | $1,150 | $2,400 | Interior hollow-core to premium exterior options |
| Installation labor (per door) | $400 | $800 | $1,400 | Labor hours vary by frame work |
| Frame and trim materials | $150 | $350 | $900 | Includes sill, jambs, and casing |
| Hardware and track system | $100 | $250 | $600 | Tracks, rollers, hinges, handles |
| Permits or inspections | $0 | $75 | $300 | Depends on locale |
| Delivery/Removal of old door | $0 | $75 | $200 | Assumes standard curbside delivery |
Bi-Fold Door Installation Price Range by Size and Kit
Typical total cost for two bi-fold doors ranges from $1,000 to $3,000 per unit, depending on door thickness, material, and whether the installation requires intricate framing. For two doors, a common interior option might fall between $1,200 and $2,800 per pair, while premium exterior kits can push higher.
Assumptions: mid-range aluminum or vinyl doors, standard wall materials, standard access, Midwest labor rates.
Key Cost Components in a Bi-Fold Door Install
Most quotes separate materials, labor, and hardware, with small add-ons for permits and disposal. A typical breakdown helps buyers compare quotes on a per-component basis and spot where savings are possible.
| Materials | Labor | Hardware | Permits | Delivery/Disposal | Warranty |
|---|---|---|---|---|---|
| $600–$1,200 per pair | $400–$1,200 per door | $100–$600 | $0–$300 | $0–$150 | 1–5 years parts; labor varies |
What Variables Most Change the Quote
Door type and size are the largest levers for price: interior hollow-core units are cheaper than solid wood or aluminum exterior kits. The number of panels and the need for custom framing, sill adjustments, or structural work also shift the total.
Other numeric thresholds include: door width (each leaf often 24–36 inches), total finished opening width (48–144 inches), and whether a fixed panel is required above the bi-fold stack.
Regional Price Variation Across the United States
Prices commonly vary by region, with higher rates in coastal urban centers and lower rates in rural areas. Expect roughly a 5–15% delta by climate zone and market tightness, plus potential surcharges for high-rise installations or complex access.
Labor Time, Crew Size, and Scheduling Realities
Most installations require 6–12 hours for a two-door kit, depending on existing frame condition and site access. Journeyman carpenters with insulation and trim skills can reduce time with pre-fabricated frames and precise measurement. A typical crew is 1–2 tradespeople, sometimes 3 for complex jobs.
Materials and Hardware Choices That Change the Price
Aluminum or vinyl frames reduce upkeep but may cost more upfront than basic wood options. Higher-end hardware, soft-close mechanisms, and low-maintenance double-glazed panels add to the price but improve longevity and usability.
Ways to Cut Bi-Fold Door Fitting Costs Without Sacrificing Quality
Control scope by opting for a standard opening and neatening existing framing rather than full structural changes. Schedule during slower seasons to improve labor availability, compare multiple quotes, and consider bundling with related carpentry or window projects.
Per-Unit Versus Per-Job Pricing Scenarios
For a typical two-panel interior bi-fold door, expect per-unit pricing in the $600–$1,200 range for doors and $400–$800 for labor per unit, with total project costs often reaching $1,500–$2,800 per opening. Per-job quotes may look different when adding permits, removal of old hardware, or regional delivery charges.

What to Ask When You Get a Bi Fold Door Quote
Ask for a line-item price breakdown, confirm included demolition or disposal, and verify any required frame or plaster work beyond the door kit. Clarify lead times, warranty terms, and whether site prep is included or billed separately.
