I recently bought a townhouse which has laundry in the finished basement. I noticed that our clothes took a bit more than an hour to dry in the dryer, so I wondered if there were any lint blockages. I also noticed that when the dryer is running, the flaps on the dryer exhaust on the exterior are barely moving.
I bought one of those 30 foot DIY lint brushes on Amazon and got to work. I actually got a pretty decent amount of lint out from brushing from the inside, even though I eventually hit a snag in the ducting with about 8' left. I intend to brush from the outside in to get the remaining lint.
When I removed the caulking and the vent cover however, I noticed a quite a bit of lint along with insulation in the wall cavity. It seems like the duct from the dryer does not fully connect to the piece of duct on the exterior vent.
My question is, am I good to add a couple more 4 inch sheet metal elbows to this duct to make sure it fully vents to the outside? I heard this will weaken the power of the dryer vent so not sure if I should do this or leave it as is.
Thanks.
