Rodent & Dead-Animal Odor
Rodent Odor Cleanup — Hidden Contamination Behind Walls & Above Ceilings
You can smell it, you can’t find it — it’s probably behind a wall, in the attic, or under the house. When a rodent dies inside a structure, the body usually ends up where you can’t reach: wall cavities, attic insulation, crawlspace ducts, behind cabinets.
Rodent contamination isn’t just one spot; it’s concentrated urine from days or weeks of nesting, and fecal matter and nesting material embedded in insulation. We’re not pest control — we handle what pest control leaves behind: the contamination inside the materials. Our structural odor remediation is backed by a 5-year written guarantee on qualifying work.

If you can smell it, we can find it. If we can find it, we can treat and seal it at the source.

The misdiagnosis
Most people think the problem is still the rodent
In many cases the rodent is already gone and what you’re smelling is what it left behind: urine soaked into insulation over weeks of nesting, and droppings compacted into wall cavities where you can’t reach.
Pest control addresses the animal; we address the contamination it leaves behind. If rodent activity is still active, start with pest control first — once entry points are sealed and the rodents removed, that’s when our work begins.
The hidden contamination
Rodents contaminate an entire pathway, not one spot — and all of it sits in places you can’t reach.
Runway residue
Oils and grime left along travel paths in walls, attics, and ducts.
Nesting urine
Concentrated urine from days or weeks of nesting.
Feces & nesting material
Embedded in insulation and compacted into cavities.

The 5-Year Written Guarantee
Qualifying surfaces treated with our proprietary Odor Encapsulator are backed by a written 5-year guarantee, subject to the documented treatment scope and written terms. The Odor Encapsulator is designed to help contain and reduce embedded urine vapors in the materials it is applied to.
It addresses pet-urine odor in the specific structural materials we treat. It does not make the property impervious to future pet accidents or odor from other sources, and it does not apply to inspections, estimates, oxidizer-only treatments, or allergen services.
