Best Duct Sealing & Aeroseal Pros in Richmond, VA
What to look for in Duct Sealing in Richmond
Duct sealing is measured, not sprayed-and-claimed — leaky ducts waste 20–30% of conditioned air (ENERGY STAR). The pros worth hiring report a before/after leakage number: Aeroseal aerosol sealing logs it automatically, and manual sealers should blower-door test. We weight Aeroseal-certified and test-capable providers above generic "we seal ducts."
- Duct sealing specialization. Provider lists Aeroseal or manual (mastic/aerosol) duct sealing as a distinct service with method detail — not a one-line claim.
- Google rating. Duct sealing is a higher-ticket job, so a strong rating floor with outcome-specific reviews is the trust threshold.
- Aeroseal / leakage-test capability. Aeroseal certification or duct-leakage testing (Duct Blaster, blower door) signals verifiable, measured results rather than visual cleanup.
Verify before you book
- Active Aeroseal dealer status (manufacturer registry is the verification step) — we accept self-claimed.
- Whether a before/after leakage test was actually run — ask for the numbers.
- Utility-rebate eligibility (e.g. AEP Texas Standard Offer) — confirm with the provider and your utility before assuming a credit.

How much should Richmond, VA homeowners expect for a basic "Duct Cleaning" inspection and report?
- What is Aeroseal duct sealing?
- Aeroseal is an aerosolized sealant blown through pressurized ductwork that seals leaks from the inside and reports a measured before/after leakage number. It's distinct from manual sealing with mastic or metal tape, which is applied by hand at accessible joints.
- How much can duct sealing save?
- Leaky ducts waste roughly 20–30% of heating and cooling energy (ENERGY STAR), so sealing can meaningfully cut bills and fix hot-and-cold rooms. The payback is faster in long-cooling-season climates. Many utilities (e.g. AEP Texas Standard Offer programs) also offer rebates — confirm eligibility before assuming a credit.
- Do duct sealing jobs in Richmond require different credentials than basic cleaning?
- Yes. Duct sealing can trigger building-code or trade-license requirements under DPOR and the 2021 USBC. Choose contractors who document sealing methods and note any applicable permit work.
- What should a Richmond duct camera inspection report include?
- Start with a clear summary of observed contamination, timestamped video or photos, and recommended actions such as sanitizing or sealing. The report should state whether work requires DPOR-licensed trade involvement.
