BathroBathroom Exhaust Fan — Installation & Replacement

Clear steam, stop odors, and protect finishes. We install quiet, code-compliant bath fans with the right ducting and exterior vent so moisture actually leaves the house—not your attic.

Why it matters

• Removes humidity that causes mold, peeling paint, and swollen doors
• Cuts mirror fog and odors faster
• Protects insulation, framing, and nearby wiring from moisture

What we install

• Quiet fans with low sone ratings for comfortable use
• Right-size airflow by room (typical 50–110+ CFM; bigger for large baths)
• Smart controls: timers, motion or humidity sensors, wall switches that auto-shutoff
• Inline or ceiling fans; wall fans where ceiling access is tight
• Proper ducting: smooth, short runs in 4–6 inch duct, sealed and insulated where needed
• Exterior termination: roof or wall vent with backdraft damper, flashed and sealed

Installation process

1. On-site assessment — measure the room, check electrical, framing, and a clear duct path to the exterior.
2. Options and written pricing after the visit — fan size, noise level, control type, vent style and location.
3. Professional install — cut-in and mount, dedicated switch or control, tight duct connections, sealed roof/wall cap.
4. Test and verify — airflow and damper check, user walk-through, simple care tips.

Common upgrades we handle

• Replacing loud, weak fans that barely move air
• Converting flex duct to smooth, properly sized runs for real airflow
• Adding humidity or motion controls to prevent forgetfulness
• Moving venting from the attic to the outside, as code requires

Code and safety, simplified

• Vent to outdoors, not into attic or crawl
• GFCI protection where required; wet/damp-rated fixtures near showers
• Correct clearances, sealed penetrations, and labeled circuits
