A Fire Risk Hiding in Your Wall

Lint builds up inside the duct, not just the trap. PREVENTilation clears the full run and proves it with a before and after airflow reading.

Warning Signs

Burning Smell

Trapped lint scorching against the heating element gives off a faint burnt-dust odor.

The Dryer Runs Hot

The unit or the vent hose feels noticeably hot to the touch partway through a normal cycle.

Clothes Take Longer to Dry

Restricted airflow traps heat inside the machine, so a load never fully dries the first time through.

Weak Airflow Outside

Hold your hand at the exterior cap while running. Barely any air movement means a blockage.

Dryer Vent Cleaning

We remove lint, blockages, and buildup from the entire vent line to reduce fire risk and restore safe airflow.

Bird Nest Removal

We safely clear nests from exterior vent hoods to restore proper ventilation and prevent dangerous obstructions.

Airflow Readings (Before & After)

We measure your dryer’s airflow before and after cleaning to prove the improvement and confirm your vent is safe.

Transition Duct & Termination Cap Replacement

We replace unsafe hoses and damaged exterior caps with proper, fire‑safe components that meet modern standards.
