Post-Rodent Air Duct Decontamination for Hampton Roads Homes
Droppings, urine, and nesting debris left behind in your ductwork blow into every room each time your system runs. We remove it all with HEPA negative-pressure vacuuming, seal the chewed ducts, and fog the system with an EPA-registered botanical sanitizer.

Signs Rodents Have Been Living in Your Ductwork
If you have dealt with mice or rats anywhere in the house, assume the ductwork needs a look — flex duct in a crawl space or attic is one of the first places rodents tunnel. Watch for:
- A musty, ammonia-like odor that gets stronger when the heat or A/C kicks on
- Scratching or skittering sounds inside walls, floors, or ceiling registers
- Droppings around floor vents, the air handler, or the crawl space entrance
- Torn or sagging flex duct with visible holes in the outer lining
- Allergy or asthma flare-ups that improve when you leave the house
- A recent pest treatment that solved the infestation but not the smell
Why a Pest Treatment Alone Doesn't Fix Contaminated Ducts
Trapping or excluding the rodents solves the infestation — but everything they left behind is still inside your air system. Droppings and dried urine break down into fine particles that get pulled into the airflow and distributed to every room in the house. The CDC specifically warns against sweeping or vacuuming rodent droppings with household equipment because it aerosolizes the contamination; duct systems need negative-pressure HEPA extraction so nothing escapes into your living space.
Rodents also cause physical damage on their way through. They chew entry holes in the outer vapor barrier of flex duct and tunnel through the insulation, which means your system may now be pulling unfiltered crawl space or attic air — dust, humidity, insulation fibers — straight into the airflow. That is why decontamination without repair is only half a fix.
Every job starts with a free digital photo inspection, so you see the droppings, nesting material, and chewed sections on camera before we quote anything. Whole-home duct cleaning starts at $312 for a single-zone home, and SmartPay financing lets you start for as little as $75 down down.
Our 4-Step Post-Rodent Decontamination Process
This is a specialized cleaning — not a standard dusting of the vents. Every step is documented with before-and-after photos:
HEPA Negative-Pressure Extraction
We connect a HEPA-filtered vacuum system to your ductwork and place the entire system under negative pressure, then agitate each duct run so droppings, nesting debris, and contaminated dust are pulled into the sealed collection unit — never into your home's air.
Repair & Seal Chewed Ductwork
Every chewed hole, torn vapor barrier, and crushed section is photographed and repaired or replaced. Open ducts don't just leak air — they are a re-entry invitation for the next rodent.
EPA-Registered Botanical Fogging
With the debris gone, we fog the full system with an EPA-registered botanical sanitizer that neutralizes odor-causing bacteria and the pheromone trails rodents leave to guide others back to the nest.
Stop the Next Infestation at the Source
Decontamination lasts only as long as the rodents stay out. Our sister company, Universal Pest & Termite, seals the exterior entry points — foundation gaps, crawl space vents, roofline openings — with chew-proof exclusion materials so the problem doesn't come back.
One Call Handles Both Halves of the Problem
Universal Duct Cleaning and Universal Pest & Termite are sister companies serving the same Hampton Roads footprint. That means the duct decontamination and the rodent exclusion can be coordinated as one project — no chasing two contractors, and no finger-pointing about whether the smell is a duct problem or a pest problem.
