Mold & Mildew Duct Treatment in Fort Myers, FL

If you smell a musty 'dirty sock' odor when the AC kicks on, see black specks around your supply vents, or notice unexplained allergy flare-ups — there's a strong chance mold is growing inside your Florida ductwork. Our antimicrobial duct treatment uses EPA-registered fog to kill mold spores at the source, then we sanitize the entire HVAC system so it stops recirculating spores into every room.

Bastion Duct Solutions provides air duct and dryer vent cleaning across Fort Myers and the broader Lee County market — Cape Coral, Estero, Bonita Springs, Lehigh Acres, and Sanibel. Post-Hurricane Ian moisture, year-round AC use, and constant Gulf-coast humidity continue to drive mold and biofilm buildup inside Fort Myers ductwork. Every cleaning uses truck-mounted negative-air HEPA vacuums and includes optional EPA-registered antimicrobial fog for storm-affected homes.

Our process in Fort Myers

1. Inspect for Mold: Camera inspection of the supply runs, evaporator coil, and return plenum to confirm what we're dealing with.
2. Deep Clean First: Mold treatment is only effective on clean surfaces — we always recommend pairing with full duct cleaning.
3. Antimicrobial Fog: EPA-registered antimicrobial introduced as a fine fog while the blower runs, coating every interior surface.
4. Dwell & Ventilate: 30-minute dwell time, then we ventilate the home before handing it back to you.

Mold & Mildew Duct Treatment FAQs — Fort Myers

Is the antimicrobial fog safe for kids and pets?

Yes — we use EPA-registered formulas approved for occupied spaces. We still ventilate the home after treatment and ask you to wait 30 minutes before re-entering.

Will this fix a major mold problem in my AC?

Surface mold in the ducts, yes. If mold is growing on the evaporator coil itself or there's water damage in the air handler, we'll flag it and recommend HVAC service first.

How long does the treatment last?

Fort Myers humidity means spores can return — most homes benefit from re-treatment every 2–3 years alongside their regular duct cleaning.

Do I need a mold test first?

Not for surface treatment. If you suspect a structural mold problem, hire a licensed mold assessor before any cleaning.
