TipKasa Team

Dryer vents require priority attention during inspections, as lint accumulation restricts airflow and creates fire hazards; use a flashlight to peer into the vent opening and look for visible lint buildup or blockages that indicate the need for professional cleaning or duct replacement.

Tool RecKasa Team

The Ryobi ONE+ 18V Handheld Blower ($60-80) effectively clears debris from soffit vents and foundation vents without requiring a ladder climb, and its compact design allows access to tight exterior spaces where leaf accumulation commonly occurs.

WarningKasa Team

Foundation vents and crawlspace vents often harbor nests from insects or small animals; inspect these vents during warmer months when activity is visible, and contact a pest control professional before cleaning if droppings or active nesting materials are present, as improper removal risks disease exposure. ---
