Step 1
Assess existing terminations and plan a direct route to exterior
Fan Ducting
Ensure bath and kitchen fans vent outdoors to protect your attic and roof. We correct improper ducting, add insulation, and make sure moisture leaves your home instead of getting trapped.
Signs You Need Fan Ducting
Attic fan vents directly into the attic instead of outside
Adds proper ducting to expel hot, moist air outdoors, preventing attic heat buildup and moisture issues.
Rust, mold, or water stains around attic fan housing
Redirects exhaust to the exterior, reducing condensation and protecting attic materials.
Attic fan runs constantly but airflow feels weak
Correctly sized, sealed ducting improves airflow efficiency and extends fan lifespan.
