Aeroseal duct sealing cost typically runs from $600 to $6,000 depending on home size, total leakage, and access. Buyers usually pay within a midrange driven by the number of registers sealed, baseline leakage in CFM, and whether repairs are needed before sealing.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small Home (1,000–1,500 sq ft) | $600 | $1,200 | $2,000 | Assumptions: 10–15 registers, <80% accessible, moderate leakage. |
| Average Home (1,800–2,500 sq ft) | $1,200 | $2,400 | $4,000 | Assumptions: 15–25 registers, typical leakage, limited pre-repair. |
| Large Home / Complex Ducts | $2,500 | $4,000 | $6,000 | Assumptions: >25 registers, high leakage, difficult access, attic or crawlspace work. |
Typical Total Price for Aeroseal Duct Sealing in a House
Most homeowners receive quotes that combine a base service fee plus a leakage-dependent charge; a realistic total price for Aeroseal duct sealing is $1,200-$2,400 for a typical 2,000 sq ft home. This average assumes 15–20 supply/return registers and pre-existing leakage of 20–40% of system flow.
Assumptions: Midwest labor rates, standard materials, normal access.
Cost Parts: Materials, Labor, Equipment, Disposal, and Overhead
| Component | Low | Average | High | What It Covers |
|---|---|---|---|---|
| Materials | $50 | $150 | $400 | Sealant, masking, small repair supplies |
| Labor | $300 | $900 | $1,800 | Technician time for prep, sealing, testing |
| Equipment | $200 | $500 | $1,200 | Rental/use of Aeroseal machine, duct blaster test gear |
| Delivery/Disposal | $0 | $50 | $200 | Minor waste removal, travel fees |
| Overhead & Admin | $50 | $200 | $400 | Project management, warranty handling |
Typical quotes add these components into a single line item or break them out; compare line-by-line.
How Duct Size, Leakage Rate, and Number of Registers Change the Quote
Three primary numeric drivers: total duct leakage (CFM50), number of registers, and total duct surface area (approx. home sq ft). Expect price jumps when leakage exceeds 500 CFM50, when registers exceed 25, or when a home is over 3,000 sq ft.
Examples of thresholds: sealing for leakage under 200 CFM50 often stays near the low range; 200–500 CFM50 moves to average pricing; >500 CFM50 typically requires the high range and more technician hours.
How to Cut Aeroseal Duct Sealing Price Before the Technician Arrives
Reduce the final Aeroseal price by controlling scope and prep: clear attic/crawlspace access, label and make registers accessible, and complete small repairs yourself. Removing insulation or opening access panels ahead of time can cut labor hours by 1–3 and lower labor costs $75-$375.
Ask for a scoped quote that excludes optional upgrades and request separate line items for pre-repair and post-seal verification tests to avoid surprise charges.
Regional Price Differences and What To Expect in U.S. Markets
Regional variations typically change quotes by ±15–35%: urban West Coast and Northeast prices trend higher, Midwest and parts of the South lower. Expect about 15% higher in major metro areas and up to 35% higher in high-cost coastal regions.
| Region | Typical Range | Delta vs. National Avg |
|---|---|---|
| Midwest | $900-$2,200 | -10% to -20% |
| South | $1,000-$2,600 | -5% to +5% |
| Northeast | $1,300-$3,000 | +10% to +30% |
| West Coast | $1,400-$3,500 | +15% to +35% |
Typical On-Site Time, Crew Size, and What Drives Labor Hours
Most Aeroseal jobs take 4–10 hours on site with a 1–2 person crew for standard homes; complex jobs can take 12–18 hours or require an extra technician. Plan for 4–6 labor hours for small homes, 6–10 for average homes, and 10+ for large or heavily leaking systems.
Labor rate assumptions: contractors commonly charge $75-$125 per hour per technician or roll costs into a per-job price; use to estimate labor portion.
Common Add-Ons, Prep Work, and Repair Charges That Increase Price
Quotes often exclude duct repairs, filter replacements, grill rebalancing, and access panel installation. Expect small repairs $150-$600, major duct replacement sections $800-$2,500, and register relocation $75-$250 each.
Diagnostic testing (blower door/duct blaster) is sometimes included; if billed separately, expect $150-$350. Ask whether the quote includes a post-seal leakage test and a workmanship warranty.
