When converting a single door to a double door, buyers typically see cost drivers centered on existing framing, hardware, and installation labor. The price reflects door type, required structural work, and local labor rates. This guide provides clear low–average–high ranges and practical pricing in USD.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $600 | $1,100 | $2,000 | Doors, jambs, hardware, shims, finishes |
| Labor | $800 | $1,500 | $3,000 | Carpentry, framing, hinge alignment |
| Permits | $0 | $100 | $400 | Depends on jurisdiction and scope |
| Delivery/Disposal | $50 | $200 | $600 | Trash removal or haul-off |
| Contingency & Overhead | $100 | $300 | $700 | Unforeseen adjustments |
| Total Project | $1,550 | $3,200 | $6,700 | Range reflects variations in region and scope |
Overview Of Costs
Typical cost range for single to double door conversions generally spans from about $1,500 to $6,700, with most projects landing between $2,500 and $4,500 under mid-range conditions. The per-unit perspective varies, often expressed as $/door or $/linear foot of additional frame work. Assumptions: standard interior doors, no structural reinforcement beyond jamb widening, no major engineering needed.
Cost Breakdown
The breakdown highlights where money goes in a typical conversion. A concise table below shows the major cost categories and supported ranges.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $600 | $1,100 | $2,000 | Doors, jambs, trim, hardware |
| Labor | $800 | $1,500 | $3,000 | Skill level varies by crew and region data-formula=”hours × rate”> |
| Permits | $0 | $100 | $400 | Most projects do not require permits, but some jurisdictions do |
| Delivery/Disposal | $50 | $200 | $600 | Material drop-off and waste removal |
| Overhead | $100 | $300 | $700 | Shop, fuel, insurance overhead |
| Contingency | $100 | $300 | $700 | Reserved for surprises |
| Taxes | $30 | $150 | $450 | Sales tax varies by state |
What Drives Price
Key price factors include door type and structural needs. Premium doors or decorative panels raise material costs, while wider or taller openings can increase trim and labor. If the wall requires re-framing, estimate shifts upward. Ceiling height, door hardware complexity, and finish work (paint or stain) also influence final pricing.
Labor, Hours & Rates
Labor costs correlate with crew size, skill level, and local wage norms. Typical packages involve 1–2 carpenters for 6–16 hours, depending on opening size and frame modifications. A regional premium may add 10–25% in metropolitan areas compared with rural zones.
Regional Price Differences
Prices vary across regions due to labor markets and material sourcing. Urban areas often show higher hourly rates, while suburban markets balance price and speed. Rural regions may offer lower labor costs but higher delivery charges for materials.
Labor & Installation Time
Conversion schedules hinge on wall structure, whether load-bearing elements are altered, and if upgrades to headers or studs are required. Typical installs take 1–2 days for standard openings, with longer timelines for complex framing or custom hardware. Assumptions: standard 80–100 in2 door set, no major structural changes.
Additional & Hidden Costs
Unexpected items can affect the total, including frame reinforcement, weatherproofing, and finish work. Hidden charges may appear for additional hardware, floor repairs after removal, or HOA approvals. Always verify whether disposal fees or recycling charges apply.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes with varying specs and labor intensity.
Basic — One standard interior double-door conversion, no structural reinforcement, measured in hours. Doors: standard hollow-core pair; minor trimming; basic hardware. Labor: 6–8 hours. Materials: $600–$900. Total: $1,600–$2,200.
Mid-Range — Standard interior double doors with light framing tweaks and mid-range hardware. Labor: 8–12 hours. Materials: $1,000–$1,400. Permits: $0–$150. Total: $2,400–$3,400.
Premium — Load-bearing wall, structural header upgrade, custom doors, and premium hardware. Labor: 14–22 hours. Materials: $1,400–$2,000. Permits/HOA checks: $200–$600. Total: $5,000–$7,000.
Assumptions: region, specs, labor hours.
