Air Duct Coatings and Restoration for Commercial and Industrial Facilities
When duct systems are damaged by mold, moisture, fire, or corrosion, replacement is not always the most efficient or cost-effective option. At Enviro-Air Services, we specialize in air duct coatings and restoration for commercial and industrial HVAC systems. Our team helps restore the performance, safety, and lifespan of ventilation systems across complex facilities without the need for full demolition or duct replacement.
Why Duct Restoration May Be the Best Solution
Over time, air ducts in commercial and industrial settings can become structurally compromised or biologically contaminated. Uncoated fiberglass-lined ducts may harbor mold, and metal duct surfaces may corrode or absorb smoke and moisture.
Air duct coatings and restoration provide a clean, sealed interior surface that:
Remediates Mold and Contamination
After mold removal, applying antimicrobial coatings helps prevent future growth and restores a safe, clean interior surface.
Seals Porous or Deteriorated Duct Surfaces
Damaged duct liners and aging sheet metal can absorb odors, particulates, and moisture. Coatings seal these surfaces and help restore integrity.
Improves Airflow and System Efficiency
Rough, deteriorated surfaces can restrict airflow. Restoration smooths interior duct walls to reduce friction and allow more efficient air movement.
Extends Duct System Lifespan
Restoration protects against future corrosion, microbial colonization, and air leaks, allowing you to delay or avoid full duct replacement.
When Is Duct Restoration Recommended?
Duct coatings and restoration are ideal when:
- Mold has been discovered and removed from duct interiors
- Smoke damage has affected metal duct surfaces
- Fiberglass-lined ducts are shedding or showing contamination
- Condensation and corrosion have caused surface deterioration
- HVAC systems have been impacted by fire, water, or long-term neglect
If you’re unsure whether restoration is possible, Enviro-Air Services can perform an on-site inspection to evaluate duct surface conditions.
Our Duct Coating and Restoration Process
Our process is built around minimal disruption and maximum compliance:
Inspection and Surface Evaluation
We begin with a full duct system assessment, using cameras and airflow measurement tools to identify contamination, liner condition, and structural degradation.
Mechanical Cleaning and Source Removal
Before coating, the duct interior is mechanically cleaned to remove all dust, mold, and debris. This ensures strong coating adhesion and compliance with NADCA source-removal standards.
Application of Professional-Grade Coatings
We apply water-based, antimicrobial, or elastomeric coatings depending on the use case. Coatings are sprayed or rolled onto duct walls to create a uniform, sealed surface.
Final Testing and Documentation
Post-application, we inspect coating coverage, verify airflow, and document the restoration with photographs and service records.
