Best Duct Sealing & Aeroseal Pros in Everett, WA
What to look for in Duct Sealing in Everett
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.

What Everett homeowners actually ask about "Duct Cleaning" — quick answers for local concerns
- 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.
- How do I find a duct sealing specialist in Everett who addresses moisture and recontamination risks?
- Look for providers who document leaks with a duct blaster or pressure test and who offer Aeroseal or other proven sealing methods. Confirm they use post-seal camera verification and explain how they will address the moisture source that caused mold or recontamination.
- When is air duct sanitizing recommended after cleaning in Everett's damp climate?
- Air duct sanitizing is recommended when camera inspection shows biological growth or persistent musty odors, especially after Everett's wet winters. Providers should explain which sanitizers they use, how they verify effectiveness, and how sealing can reduce recontamination risk.
