Duct Coating
Extend the Life of Your Duct System with Duct Coating
After a professional duct cleaning, your system is free from dust, debris, and microbial growth — but without a protective seal, those issues can return. GreenFox offers advanced duct coating services using IAQ 800, a professional-grade antimicrobial coating that seals the interior of your ductwork to help prevent future contamination and maintain cleaner, healthier indoor air.
What Is Duct Coating?
Think of duct coating as similar to relining old iron pipes. Instead of replacing the entire system, we apply a durable interior coating that seals, strengthens, and stabilizes the existing structure from within. This approach is especially valuable for older ductwork made of fiberglass or duct board, which can become brittle and porous over time.
When these aging materials begin to break down, they not only reduce air quality — they can also release fibers and create airflow restrictions. In fact, in some cases, a standard duct cleaning can agitate deteriorating duct board, causing even more shedding or damage. That’s why duct coating is often recommended immediately after cleaning in these systems
Why Duct Coating Matters
In homes across Palm Beach County, duct systems are exposed to high humidity, microbial growth, and wear over time. Many older systems — especially those using duct board or fiberglass — become porous and break down, releasing fibers and harboring contaminants even after cleaning.
Coating the ductwork with IAQ 800 offers multiple long-term benefits:
- Prevents future mold and mildew growth inside the duct system
- Seals porous surfaces and locks in residual dust or particles
- Reduces fiberglass shedding into your breathable air
- List Enhances system performance
- Helps maintain indoor air quality after remediation or duct cleaning
Our Duct Coating Process
1. Preparation: We perform a duct cleaning to prepare the duct surfaces to ensure proper adhesion of the coating material.
2. Application: Using a specialized applicator, we apply an anti microbial latex duct coating material to the interior surfaces of the ductwork, creating a durable and protective barrier.
3. Curing: The coating material is allowed to cure and dry, forming a over-seal that protects and partially restores the ductwork from moisture, pollutants, and other environmental factors.
Who Should Consider Duct Coating?
- Homes with fiberglass-lined ductwork or duct board
- Properties with a history of mold in the duct system
- Older HVAC systems showing signs of wear or fiber shedding
- Homeowners who’ve completed a full duct cleaning and want added protection
- Allergy-sensitive households or homes with indoor air quality concerns
