Decomposition odor is one of the most persistent and distressing issues a property owner can face. Whether caused by an unattended death or other biohazard situation, the smell can linger far longer than expected without proper treatment.
What Causes Decomposition Odor?
Decomposition odor is caused by the breakdown of organic matter, which releases gases such as putrescine and cadaverine. These compounds create the strong, unmistakable smell associated with decomposition.
How Long Does the Smell Last?
The duration of decomposition odor depends on several key factors:
- Temperature: Warmer environments like Florida accelerate decomposition and intensify odors
- Time undiscovered: The longer the delay, the deeper contamination spreads
- Materials affected: Porous materials such as carpet, wood, and drywall absorb odor
In many cases, odors can linger for weeks or even months if not professionally treated.
Why the Smell Doesn’t Go Away on Its Own
Decomposition odors penetrate far beyond the surface. They can seep into:
- Subflooring
- Insulation
- Furniture
- HVAC systems
Standard cleaning methods only remove surface odors, leaving the source untouched.
How Professionals Remove Decomposition Odor
Professional biohazard cleanup teams use advanced techniques to eliminate odors at the source:
- Industrial-grade enzyme treatments
- Ozone or hydroxyl generators
- Removal of contaminated materials
- Deep structural cleaning
This ensures the odor is completely removed rather than masked.
When to Call a Professional
If the smell persists after cleaning or becomes overwhelming, it’s critical to contact a certified biohazard cleanup team immediately. Delays can worsen contamination and increase restoration costs.
