Expert Verdict — Reviewed by the SuperArbor Pro Desk

Utility vents are the finishing touch that keeps a vinyl siding job looking clean around dryer and bath-fan terminations. Always match the vent color to the exact siding color name, since tones like Pebblestone Clay and Wicker vary between manufacturers. Choose the 8-1/8 in. size when the wall opening or duct hood is larger, and make sure the duct behind the vent is sealed and supported so airflow is not restricted.

When cutting siding and sheathing for a vent penetration, check for wiring and wear eye protection, and ensure dryer exhaust is vented to the exterior per code.


Match your utility terminations to your siding with a Mastic INTVENT intake/exhaust vent in the right color and size.
