Any vertical run in the exhaust path. Lint lifted partway up and not carried over settles at the base, making the bottom of a rise the primary accumulation point in many second-floor laundry systems — and usually the least accessible part of the run.

We work on vertical rise every week across DFW. CSIA-certified, written quotes, financing available.
Flat fee confirmed when you book. Same-week scheduling. A pass/fail verdict within 48 hours.
No airflow, overheating dryer, burning smell, or a vent you're not sure about? We answer 7 AM to midnight and the assessment ends in a written safe-to-use verdict — including a do-not-use notice when the evidence supports one. After-hours dispatch runs subject to crew availability.
