If you're selling a house, a bathroom exhaust fan that doesn't vent outside is a real, common reason an inspection comes back with a problem. Joe has fixed this exact issue on more than one Decatur-area home.
The Mistake Is More Common Than You'd Think
It's easy to assume a bathroom fan is doing its job because it turns on and makes noise. But plenty of homes have fans that vent into an attic, a ceiling cavity, or nowhere at all, instead of through a duct to the outside. It's invisible until someone goes looking, which is exactly what a home inspector does.
Why It Fails An Inspection
Venting moist bathroom air into an enclosed space instead of outside builds up moisture where it can't escape, which is a mold and rot risk inspectors are specifically trained to flag. Joe has corrected this on a house where two separate bathroom vents weren't going outside, which was the reason the sale nearly fell through.
The Fix Is Straightforward Once You Know What To Look For
Running proper ducting from the fan housing to a real exterior vent solves it. It's a small job compared to the problem it prevents. If you're getting ready to sell and aren't sure your bathroom fans actually vent outside, it's worth a quick look before a buyer's inspector finds it for you. Call (260) 216-1100.
