Did you know that over 90% of appliance-related home fires start in clothes dryers? According to the National Fire Protection Association (NFPA), nearly 16,000 home structure fires are caused by dryers or washing machines each year — and most are due to lint buildup and poor airflow.
As home inspectors, we see this risk more often than you'd think. Whether you're a REALTOR helping clients prepare a home for sale or a homeowner doing seasonal maintenance, these six expert tips can help prevent a dryer fire:
Home Inspector's Safety Checklist
- Clean the lint screen before every load.
If clothes are still damp or drying takes longer than usual, airflow may be blocked.
- Inspect and clean the dryer vent annually.
Hire a professional if needed — prices typically range from $99–$200. Make sure the exterior vent has no screen, a working flapper, and strong airflow when the dryer is running.
- Check duct length and configuration.
Refer to the dryer’s User Guide. Long or kinked ducts can trap lint and restrict airflow.
- Vacuum around and under the dryer regularly.
Lint can accumulate in hidden areas. Keep flammable items away from the dryer.
- Replace plastic accordion-type ducts.
Use rigid or semi-rigid metal ducts with a slight downward slope to prevent water and lint buildup.
- Be cautious with chemically soiled clothing.
Items exposed to gasoline, cooking oils, or cleaning agents should be washed more than once and dried on low heat.
