Post-Construction Dust & Air Quality Cleanup in St. Charles, MO

Renovations and construction projects can dramatically improve your home, but they also leave behind one of the most harmful types of indoor air pollution — fine particulate dust. Even after the contractors clean up, microscopic dust from drywall, flooring, sawing, sanding, and demolition lingers inside your air for weeks or months. This dust settles into vents, cold air returns, carpets, furniture, and even inside your HVAC system.

At Green Air Duct Cleaning St Charles, our Post-Construction Dust & Air Quality Cleanup service is designed to remove the contamination that general cleaning cannot reach. We specialize in high-level particulate removal, HVAC system flushing, and air quality restoration after remodeling, basement finishing, kitchen overhauls, additions, and new home builds.

If your home feels “dusty” no matter how many times you clean it, this is the service you need.

Why Post-Construction Dust Is So Dangerous

Unlike regular house dust, construction dust contains ultra-fine particles that stay airborne for long periods. These particles are small enough to bypass your HVAC filter, enter your airways, and circulate throughout the home nonstop.

Common post-construction contaminants include:

  • Drywall dust

  • Wood sanding particles

  • Silica dust

  • Flooring and tile dust

  • Insulation fibers (fiberglass & cellulose)

  • Sawdust

  • Concrete dust

  • Paint and adhesive particles

  • HVAC construction debris

These ultra-fine particles trigger allergies, respiratory irritation, sinus problems, and long-term air quality issues.

Signs You Need Post-Construction Air Cleanup

Homeowners in St. Charles typically contact us after noticing:

  • Dust returning quickly on surfaces

  • A film of powder on furniture and floors

  • Dust blowing out of vents when the HVAC turns on

  • Persistent sneezing, coughing, or throat irritation

  • Musty or chemical odors lingering after renovation

  • Dust buildup around vent covers or cold air returns

  • Thick dust inside the furnace cabinet or blower compartment

Even new homeowners experience these issues when builders run the HVAC system during construction (a very common practice).

Our Post-Construction Cleanup Process

Our cleanup process is designed to eliminate the ultra-fine particulate matter that simple sweeping and vacuuming cannot reach. Here’s what our comprehensive service includes:

1. HVAC System Cleaning

We remove construction dust from:

  • Supply and return ducts

  • Blower motor

  • Furnace cabinet

  • Evaporator coil housing

  • Registers and vents

2. HEPA Air Scrubbing

Removes airborne particles still floating inside the home.

3. Cold Air Return Flushing

This area collects the majority of construction dust and must be deep-cleaned.

4. High-Pressure Duct Vacuuming

Removes drywall, insulation, and silica dust from duct interiors.

5. Surface-level IAQ Assessment

Identifies leftover areas of contamination.

6. Post-cleaning air refresh

Circulates clean airflow throughout the home after service completion.

By treating both the air and the HVAC system, we ensure your air quality returns to safe, normal levels.

Who Should Get This Service?

Post-construction air cleanup is recommended for:

  • Homes recently remodeled

  • New builds before moving in

  • Homes with newly installed flooring or countertops

  • Finished basements

  • Homes that had demolition or removal of old materials

=I called in thinking that I would have to wait days until someone could come out and check my ventilation system. I noticed poorer ventilation in my bathroom, and I was concerned about the impact since I do not have windows in there. Surprisingly, Nathan was able to send someone out the same day! I was guilty of not having my air duct system checked sooner but his team was able to come out and clean the bathroom exhaust fan. No more waiting hours for my bathroom to ventilate after a shower!

John Bennington

We always contact Nathan when our business needs a routine cleaning for the air ducts. He sends his team out for a free quote and lets us know what needs to be done. I can attest that the products he offers are high quality and have actually reduced the amount of times we have needed to replace parts. I know that my workers are breathing in healthy and clean air thanks to the great work this company does.
