Dryer Vent Inspection in Portland, OR
Ensure Your Dryer Vent System Is Safe, Efficient & Code Compliant
Why Regular Dryer Vent Inspections Matter
Many dryer vent problems are invisible until they cause a fire, a flooded laundry room, or a dryer that dies prematurely. A professional dryer vent inspection catches hidden issues before they become expensive emergencies.
At Dryer Vent John, we provide comprehensive dryer vent inspections for homes, apartments, and businesses in Portland, OR, and the surrounding metro area. Our CSIA certified technicians assess your entire vent system — from the dryer connection to the exterior exhaust — checking for blockages, damage, code violations, and performance issues.
When to Schedule a Dryer Vent Inspection
We recommend a professional dryer vent inspection in these situations:
- Annual maintenance — Catch lint buildup, damage, and code issues before they become dangerous
- Buying or selling a home — Verify the vent system is safe, functional, and code compliant for the home inspection
- After a new dryer installation — Confirm the existing vent system is compatible with your new appliance
- Persistent dryer problems — Clothes not drying, overheating, error codes, or burning smells despite recent cleaning
- Insurance or landlord requirements — Documented inspection for compliance or liability purposes
- After pest activity — Birds, rodents, or insects may have built nests or caused damage inside the vent
- Older homes — Homes built before modern code may have vinyl ducts, excessive runs, or improper terminations
What Our Dryer Vent Inspection Covers
Our inspection goes far beyond a quick visual check. We assess every component of your vent system:
Vent Material Assessment
We check whether your duct material meets current code — rigid aluminum vs. prohibited vinyl or foil flex. Wrong materials are a fire risk and code violation.
Vent Length & Routing Analysis
We measure total equivalent vent length (including deductions for bends) to verify compliance with code maximum limits. Overly long or complex routes restrict airflow and cause overheating.
Connection & Joint Inspection
We check every connection point for gaps, disconnections, tape failures, and lint leaks. Loose joints let hot, lint-laden air escape into walls and crawl spaces.
Exterior Vent Cap Check
We inspect the exterior termination for damage, blockage, pest intrusion, stuck damper flaps, and proper weather sealing.
Airflow Performance Test
We test actual airflow output at the exterior vent to verify the system is performing at safe levels. Weak airflow indicates hidden blockages or damage.
Lint Accumulation Assessment
We evaluate lint buildup throughout the system — inside the vent, at transition points, and in the dryer cabinet — to determine if cleaning is needed.
Benefits of Professional Inspection
Catch Problems Early
Hidden disconnections, crushed ducts, and lint accumulation create fire hazards you can't see. Inspection finds them before they cause damage.
Verify Code Compliance
Oregon building code specifies vent materials, maximum lengths, and installation requirements. An inspection confirms your system meets all standards.
Protect Your Home Investment
A documented inspection protects you during home sales, insurance claims, and rental property compliance checks.
Prevent Expensive Repairs
Catching a minor disconnection or lint buildup now prevents a house fire, a flooded wall, or a burned-out dryer later.
Peace of Mind
Know your dryer vent system is safe, efficient, and working as designed — especially in older homes or after moving into a new property.

Frequently Asked Questions
At least once a year, or anytime you notice dryer performance issues, move into a new home, or install a new dryer. Properties with multiple units or heavy usage should inspect more frequently.
An inspection assesses the condition, safety, and code compliance of your vent system. Cleaning removes lint and debris. Often both are done together, but an inspection may reveal problems that cleaning alone can't fix.
Yes. We document our findings and provide recommendations for any repairs or improvements needed.
Most inspections take 30–45 minutes. If cleaning or repairs are needed, we can often handle them on the same visit.
Absolutely. Catching a small issue during inspection costs far less than repairing fire damage, replacing a burned-out dryer, or remediating mold from a leaking vent.
