Dryer Vent Core Drilling

Installing or relocating a clothes dryer requires a vent penetration through an exterior wall to exhaust hot, moist air outside the building. When the wall is poured concrete, concrete block, brick, or stone, the penetration requires diamond core drilling to create a clean, round hole without damaging the wall structure. REDCORE provides dryer vent core drilling services throughout Massachusetts, drilling standard 4-inch and 4.5-inch diameter holes through foundation walls and exterior walls of any material for dryer exhaust duct installation.

The hole must be positioned at the correct height for the dryer connection, drilled with a slight downward pitch toward the exterior to prevent rain and condensation from entering, and located where the exterior vent cap will function properly away from windows and air intakes. REDCORE operators position each penetration precisely, drilling through poured concrete foundation walls, CMU block, brick veneer, and composite wall systems with equal reliability. The finished hole has smooth interior walls that allow the vent duct to pass through cleanly and accept a wall sleeve for proper sealing.

This is a quick, affordable service that we provide for homeowners, appliance installers, and property managers across Massachusetts. Most dryer vent penetrations are completed in under 30 minutes including setup and cleanup. We also drill penetrations for bathroom exhaust fans, range hood venting, and other small-diameter exhaust applications that require a clean hole through a masonry or concrete wall.
