Bi-Fold door installation costs vary with door size, material, hardware, and site conditions. This article outlines typical price ranges, what drives the cost, and practical ways to budget accurately for a new bi-fold system.
Cost awareness helps buyers compare quotes and plan a realistic budget for a bi-fold door project.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door kit (two-door bi-fold set, standard hollow core) | $350 | $600 | $1,100 | Includes track, jambs, and hardware |
| Labor for hinge and frame prep | $150 | $450 | $900 | Based on existing opening condition |
| Installation milestone (complete door set in place) | $350 | $900 | $1,500 | Per set, average project |
| Finishing (painting/staining to match trim) | $80 | $180 | $350 | Depends on finish level |
| Permits or inspections | $0 | $150 | $500 | Region-dependent |
| Delivery/Handling | $0 | $50 | $150 | If not included with kit |
Bi-Fold Door Installation Price Ranges by Door Size
Assumptions: standard 4-foot to 8-foot openings, two-panel leaves, interior use, mid-range hardware.
The total price typically ranges from $900 to $2,400 for standard interior hollow-core bi-fold doors, including kit and labor. For larger openings or higher-end materials, totals can climb to $3,000 or more when premium finishes, solid-core construction, or heavy-duty hardware are used.
Major Cost Components in a Bi-Fold Door Project
The quote breaks into four to six primary parts. Hardware and track systems often set the pace for price variation.
| Cost Component | Low | Average | High | Typical Influence |
|---|---|---|---|---|
| Door kit (two-panel set) | $350 | $600 | $1,100 | Material and finish determine price |
| Labor for framing and alignment | $150 | $450 | $900 | Opening condition and square footage matter |
| Finish and paint | $80 | $180 | $350 | Color match and surface prep add cost |
| Permits/inspections | $0 | $150 | $500 | Local rules drive variability |
| Delivery/haul-away | $0 | $50 | $150 | Handled by contractor or supplier |
| Hardware upgrades | $20 | $120 | $300 | Soft-close, dampers, or handles affect price |
How Size, Material, and Frame Type Shift the Quote
Material options include hollow-core, solid-core, wood, or aluminum. Solid-core and aluminum systems typically cost more but offer better durability and longevity. Frame type (vinyl, wood, aluminum) also changes long-term maintenance costs. A standard 6-foot opening with hollow-core panels might land in the $900-$1,800 range, while a 9-foot opening in solid wood with premium hardware could reach $2,500-$4,000.
Regional Labor Rates and Their Impact on the Budget
Labor prices vary by region, urban density, and contractor availability. Inexpensive markets may see labor of $40-$70 per hour, while metropolitan areas commonly quote $60-$120 per hour. Expect higher overall cost if a custom fit requires reframing or extensive threshold work.
Typical Labor Time and Crew Size for a 6-Panel Bi-Fold Door
A typical install uses a two-person crew over 6-10 hours for interior openings. For larger or more complex openings, schedule 2-3 workers over 10-18 hours. Time scales with opening irregularities and existing trim removal.
Ways to Cut Costs on a Bi-Fold Door Project
Options include choosing standard off-the-shelf sizes, using hollow-core rather than solid-core, reusing existing trim when possible, and scheduling during non-peak times. Bundling delivery with installation can reduce overall charges.
Unexpected Fees to Expect in Permits and Disposal
Some cities require a permit for new interior doors if structural changes are involved; inspections may add $100-$300. Disposal of old hardware or doors can add $25-$100 per item. Assumptions: standard urban permitting, typical disposal services.
Comparing Materials: Hollow-Core Versus Solid-Core Versus Aluminum
Hollow-core doors are the most economical option, typically $350-$600 per kit, with labor bringing total to around $900-$1,400. Solid-core increases the kit price to $700-$1,200, and aluminum systems can run from $1,000-$2,000 for the kit alone, with higher installation costs when trimming and sealing are involved.
Estimated Per-Leaf and Per-Set Pricing Details
Bi-fold doors are priced as a set, commonly two leaves, but configurations vary. A basic two-leaf kit may cost $350-$600, while premium two-leaf kits with upgraded hardware reach $900-$1,800. When installing a four-leaf system, expect volumes to double in kit cost and labor. Per-leaf price often falls as quantity increases due to bulk hardware savings.
