Why Inspection Matters Beyond Cleaning
A dryer vent cleaning that doesn't include a proper inspection is incomplete. Lint removal addresses one hazard, but dryer vent systems can have multiple issues that affect safety and performance — issues only visible to someone who knows what to look for.
A good inspection identifies problems before they cause fires, dryer failures, or costly repairs. The inspection component of professional cleaning is as valuable as the cleaning itself for many homeowners.
What Gets Inspected
A comprehensive dryer vent inspection covers these components: the flexible connector between the dryer and the wall duct (checking for kinks, tears, or improper plastic material), the rigid duct sections through walls, floors, or attic (checking for damage, crushing, or disconnection), the number and sharpness of bends in the duct run (too many bends restrict airflow by code), total duct run length (most codes limit total run to 25 to 35 feet depending on configuration), and the exterior termination cap (checking for damage, screen obstruction, or pest intrusion).
Common Issues Found During Inspection
In Bloomington homes, inspections commonly turn up: flexible accordion-style plastic duct that should be replaced with rigid metal, vent runs that exceed recommended lengths due to previous modifications, partially crushed duct sections behind the dryer or in wall cavities, exterior caps with screens that accumulate lint and restrict airflow, and disconnected duct sections that are venting into wall cavities instead of outside.
Each of these issues affects fire risk and dryer performance independently of lint buildup.
Inspection Documentation
After a thorough inspection, ask your technician for a summary of findings — not just 'all clear' but specific notes on duct material, run length, bend count, and any issues found. This documentation is useful for your home's maintenance records and can be valuable if you sell the home or need to make a warranty or insurance claim.
