Aeroseal Duct Sealing Cost: Typical Prices and What Affects Them

Aeroseal duct sealing cost typically ranges from $600-$4,500 depending on home size and starting leakage. Most U.S. homeowners pay an average of $1,200-$2,200 for a single-family house with moderate leakage; major drivers are home square footage, measured CFM50 leakage, and duct accessibility.

Average Total Price For Aeroseal Duct Sealing Jobs

Typical total price for a whole-house Aeroseal application is $600-$4,500 with most single-family homes falling between $1,200-$2,200. This range assumes 1,000–3,000 sq ft homes, baseline leakage 200–1,000 CFM50, and standard attic or crawlspace access.

Smaller condos or targeted branch sealing often cost $300-$900; commercial systems start much higher because of duct volume and multiple zones.

How Job Quotes Break Down By Materials, Labor, and Equipment

Understanding line items helps compare quotes; Aeroseal quotes include machine time and diagnostic testing, not just a material charge. Most of the charge is equipment and labor rather than consumable materials.

Assumptions: labor hours 3–12, hourly_rate $75-$125 per hour.

Which Variables Most Affect The Final Aeroseal Quote

Two dominant variables are starting leakage (CFM50) and duct volume/length; both scale the sealant quantity and run time. Jobs with starting leakage under 200 CFM50 often fall under $1,000 while jobs over 1,000 CFM50 commonly exceed $2,500.

Other variables: 1) Accessibility—attic/crawlspace access vs. walls increases labor hours by 30%-100%. 2) Duct material—metal vs. insulated flex can change adhesion and prep work. 3) System size—duct systems >3,000 linear ft drive higher equipment run time.

How To Reduce The Price Of An Aeroseal Duct Sealing Job

Controlling scope and prep work lowers cost: address obvious duct damage first, clear attic access, and schedule during off-peak seasons. Removing obstructions and pre-sealing large tears can cut machine time and save 15%-40% on the final quote.

• Bundle with HVAC tune-up or filter change to reduce mobilization fees.
• Opt for targeted branch sealing instead of full system if leakage is localized.
• Get 3+ written quotes and request measured pre- and post-seal CFM50 results to compare value.

Regional Price Differences And What To Expect In Your Market

Prices vary by metro area; expect 10%-30% higher costs in coastal metros and 10%-20% lower in rural Midwest markets. Example deltas: West Coast prices typically +15%-30%, Northeast +10%-20%, Midwest -10%-20% relative to national averages.

Assumptions: contractor density, labor wage differentials, and travel distances affect these percentages.

Typical Job Time, Crew Size, And How That Impacts Price

A standard whole-house Aeroseal job takes 3–8 hours with a 1–2 person crew; larger systems may take 8–16 hours with a 2–3 person crew. Longer run times translate directly to higher labor and equipment charges—expect hourly-based fees if a contractor bills by the hour.

Sample labor rates: $75-$125 per hour for certified technicians; some companies bundle a flat fee that includes machine time.
