Reroute ductwork cost varies widely based on the volume of ducting moved, material type, and access difficulty. Typical buyers pay from a few hundred dollars for short flexible-duct reroutes to several thousand for full trunk-line relocations; major drivers are linear feet rerouted, duct diameter, and ceiling access.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total Project | $300-$800 | $1,200-$3,000 | $4,000-$12,000 | Assumptions: 1-3 vents to full trunk reroute; typical labor; suburban U.S. |
| Per Linear Foot | $4-$9 per ft | $10-$18 per ft | $20-$40 per ft | Depends on material (flex vs. sheet metal) and access |
| Labor Rate | $75-$95 per hour | $95-$125 per hour | $125-$180 per hour | Includes technician and helper |
Typical Total Price to Reroute Ductwork in a Home
Most single-room reroutes using flexible duct run about $300-$800; moving a supply trunk across a ceiling or through walls averages $1,200-$3,000; whole-house reroutes with new sheet-metal ducts can reach $4,000-$12,000. Buyers should expect the average residential reroute to fall between $1,200 and $3,000 for moderate scope work.
Assumptions: Single-family home, standard 8–9 ft ceilings, normal attic or crawlspace access, no major drywall replacement.
Material, Labor, Equipment, and Disposal Line-Items
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $4-$9 per ft (flex), $10-$25 per ft (sheet metal) | $75-$150 per hour; 2–16 hours | $0-$200 day rental (lift, scaffolding) | $0-$500 | $50-$300 |
Typical quotes separate material line items from labor hours and list equipment or rental charges explicitly.
Assumptions: Midwest labor rates, standard materials, normal access.
How Duct Length, Runs, and Diameter Change Quotes
Expect per-linear-foot pricing for straightforward runs: small flex runs $4-$9 per ft, 6–8″ sheet-metal ducts $12-$20 per ft, larger 10–14″ trunks $20-$40 per ft. Longer runs with more fittings add 10–30% in material plus 15–50% more labor per 100 ft increment.
Numeric thresholds that shift pricing: adding more than 50 linear feet usually moves a job from small to medium pricing; trunks over 12″ diameter typically require heavier gauge sheet metal and higher labor rates.
Practical Ways to Lower Reroute Ductwork Price
Keep runs shorter by relocating outlets or using existing chases, choose insulated flex where code permits, and do minimal drywall repair yourself to trim contractor hours. Providing clear access (clearing attic space, moving stored items) commonly reduces labor hours and the overall quote.
Other cost controls: request bundled work with HVAC service, accept standard fittings instead of custom transitions, and schedule work in shoulder seasons to avoid peak rates.
Price Differences by Region and Urban vs Rural Markets
| Region/Market | Price Delta vs National Average | Typical Total Range |
|---|---|---|
| Northeast / Metro | +15% to +35% | $1,400-$4,500 |
| Midwest / Suburban | -5% to +5% | $1,000-$3,200 |
| South / Rural | -10% to 0% | $900-$2,800 |
| West Coast / High-Cost Cities | +20% to +45% | $1,500-$6,000+ |
Urban labor and permit rates drive the largest regional differences; expect higher minimum charges in big cities.
Common Add-Ons, Access Work, and Permit Fees That Raise a Quote
Typical extras include new boot and register installation ($25-$150 per fixture), drywall patching ($75-$250 per patch), insulation wrap ($3-$8 per ft), and diagnostic or travel fees ($50-$150). Full ceiling removal and restoration or structural openings can add $500-$3,500 depending on finish level.
Assumptions: interior finish repair priced for mid-grade drywall and paint; specialist subcontractors increase cost.
Three Real-World Quote Examples With Specs and Pricing
| Example | Scope | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Small Bedroom Move | Reroute 2 flex runs, 15 ft each | 2–3 hours | Flex $5 per ft; labor $95/hr | $300-$650 |
| Single-Trunk Relocation | Move 8″ trunk 25 ft through attic | 8–12 hours | Sheet metal $15/ft; labor $110/hr | $1,400-$3,200 |
| Whole-Floor Redistribution | Replace and reroute multiple trunks, 100+ ft | 24–60 hours | Trunk $22/ft; labor $120/hr; lift rental | $4,500-$12,000 |
These examples show how scope and hours scale quickly—small changes in linear footage or trunk size have outsized effects on totals.
