Typical costs for a blower door test fall in the hundreds to about a thousand dollars, depending on home size, equipment used, and whether the test includes follow-up recommendations. Key drivers are home square footage, number of testing zones, data logging, and whether leakage remediation work is performed by the same provider.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Blower door test service | $350 | $500 | $900 | Includes depressurization, blower operation, and basic leak identification |
| Thermal imaging (optional) | $150 | $250 | $500 | For identifying hidden leaks |
| Post-test inspection & follow-up report | $100 | $200 | $400 | Recommendations and remediation scope |
| Remediation work (if performed by same provider) | $0 | $2,000 | $6,000 | Depends on envelope defects and retrofit scope |
| Permits or code compliance fees | $0 | $50 | $300 | Regional requirements may apply |
Overview Of Costs
Costs for a blower door test typically range from $350 to $900 for standard homes, with potential increases for larger homes, multiple zones, or add-ons like thermal imaging. The per-square-foot pricing is rarely advertised, but households often see the most value when tests cover the whole envelope rather than a single room. Assumptions: region, home size, and test scope.
In many markets, a basic test without extras costs roughly $350-$600, while a comprehensive package with diagnostics and a detailed remediation plan can reach $1,000-$1,800.

What Drives Price
Home size and envelope complexity are primary drivers, with larger homes or those with many levels or air leaks requiring more test points. Test scope (basic vs. diagnostic, post-remediation verification) also changes price. SEER-rated HVAC or dampers and window/door retrofit needs can add to cost if evaluated during the test.
Ways To Save
Bundle tests with other energy services (e.g., duct leakage testing, insulation evaluation) to secure a package discount. Scheduling in off-peak seasons and selecting a regional provider with standardized pricing can reduce hours and travel fees. Consider doing only the essential test if a full diagnostic is not required by code or insurer.
Regional Price Differences
Prices vary by region due to labor rates and travel costs. In the Northeast, expect higher labor and trip charges; the Midwest often shows middle-range pricing; the West may see premium rates for travel and demand-driven pricing. Typical regional deltas: Northeast +10–20%, Midwest ±0–15%, West +5–15%.
Labor, Hours & Rates
Labor for technicians typically runs $60–$120 per hour, depending on credentials and local demand. A basic blower door test commonly requires 2–4 hours of hands-on work, with longer durations for complex or multi-story homes. Assumptions: region, tests, and crew size.
Additional & Hidden Costs
Hidden costs may include extra travel fees, expedited scheduling, or mandatory follow-up visits if leaks are complex to document. Some providers charge for printed reports or data transfer. Always confirm inclusions and exclusions in a written quote.
