Aeroseal duct sealing cost typically ranges from $600 to $6,000 depending on home size, duct condition, and access. Buyers usually see an average total of $1,200-$3,000 for a single-family home; major drivers are square footage, total duct leakage (CFM50), and required prep work.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house Aeroseal | $600 | $1,200-$3,000 | $6,000 | Smaller homes or limited zones to large multi-level homes |
| Per-duct run / spot sealing | $150 | $300-$700 | $1,200 | Single run or a few accessible trunks |
| Commercial / large systems | $2,000 | $5,000-$12,000 | $30,000+ | Large tonnage systems or long run lengths |
Typical Aeroseal Duct Sealing Price For A Whole-House System
For a 1,200-2,500 sq ft U.S. single-family home with average attic/crawl access and 8-12 total vents, expect $1,200-$3,000 total; low end assumes minor leaks and easy access, high end assumes extensive sealing or multiple zones. Assumptions: Midwest labor rates, standard materials, normal access.
Most homeowners pay between $1,200 and $3,000 for a full-house Aeroseal job under typical conditions.
Parts Of An Aeroseal Quote: Materials, Labor, Equipment, Delivery/Disposal
An itemized quote normally separates materials, labor, equipment rental, and disposal or traffic control. Assumptions: residential HVAC, 1-2 tech crew.
| Materials | Labor | Equipment | Delivery/Disposal |
|---|---|---|---|
| $50-$250 (sealant) | $300-$1,500 () | $200-$800 (Aeroseal machine rental or operator fee) | $50-$300 (containment, trash) |
Labor and equipment typically make up 70%–90% of the total price for residential jobs.
How Home Size, Total Duct Leakage (CFM50), And Duct Length Change The Price
Price scales with measured leakage (CFM50), duct surface area, and run length. Jobs under 200 CFM50 often fall near the low end; 200–800 CFM50 is common and hits the average range; systems above 1,000 CFM50 or with >300 linear ft of trunk/branch reach the high end.
Two numeric thresholds to watch: under 200 CFM50 (low cost) and over 1,000 CFM50 (significantly higher cost).
Common Add-Ons, Prep Work, And Site Conditions That Increase Price
Typical add-ons include duct access panels ($50-$200 each), fibrous insulation repair ($200-$800), sealing inaccessible plenums, and mold or pest remediation. Tight attics, multi-level homes, or obstructed crawlspaces add labor time and therefore cost.
Expect $200-$1,500 extra when repairs, access panels, or insulation fixes are required before Aeroseal can be applied.
How Prices Vary By U.S. Region And Market Type
Regional labor and permit differences matter: Coastal urban areas tend to be 10%-30% more expensive than the national average; rural and lower-cost Midwest/South markets can be 10%-20% cheaper. Example: $1,200 average in Midwest vs. $1,500-$3,900 average in high-cost metro regions.
Budget planners should add 10%-30% to local quotes in pricey metropolitan markets.
Labor Time, Crew Size, And Typical Job Duration
Most residential Aeroseal jobs use a two-person crew working 3-8 hours for 1,200-2,500 sq ft homes; larger systems take 1-3 days with additional crew. Hourly contractor rates including benefits are often $75-$125 per hour per tech.
Typical labor estimate: 3-8 hours for most homes, with crew of two common; factor $75-$125/hour when estimating labor cost.
Practical Ways To Lower The Aeroseal Price On A Home
Control scope by sealing only the most-leaky zones, do basic prep yourself (clear attic space, label vents), get at least three competitive quotes, and schedule work off-season when contractors have lower demand. Choosing standard instead of premium-access panel materials saves money.
DIY prep plus comparing 3+ local quotes can reduce the final price by 10%-30% without compromising the core service.
Real-World Example Quotes To Use As Benchmarks
Example A: Small bungalow, 900 sq ft, 150 CFM50 — $650 total, 3 hours, minimal prep. Example B: 2,200 sq ft suburban home, 420 CFM50 — $1,900 total, 6 hours, one access panel added. Example C: 4,000 sq ft multi-zone house, 1,200 CFM50 — $6,500 total, 2 days, insulation repair included.
Use these real examples to compare quotes against measured CFM50 and stated scope.
