Dryer Vent Replacement

In a 34-year-old house I have a dryer vent located just above floor level on the first floor. It goes into the interior wall, immediately makes a vertical 90 degree angle turn between two walls, then rises about 8 feet to the chase between the first and second floor, then makes a horizontal 90 degree angle turn and runs about 20 feet to the exterior of the house where it exits. In other words, it goes in, then up, then out. The problem is there is a break somewhere along the line so that the exhaust never exits the house, which, obviously, has resulted in moisture problems.

My question is: Is there any way, other than tearing out drywall walls or ceilings, to remove the old venting and install new venting? Specifically, I'm wondering how to fish new ducting through these turns. If that is not possible, how can I remove & replace the ductwork and minimize the drywall work I'll have to do?


Update: I have already snaked the venting & it is clear.

Dryer Vent Replacement

Unfortunately, that is the most direct route.

Dryer Vent Replacement

Theoretically, you can "blow" a flexible fabric pipe in there and then inject a hardening resin to give it shape inside the existing duct (used mostly for leaking drains). Don't know how well this approach would work for a dryer vent, though.
