Dryer Vent Installation & Repair in Denver, CO

If it's white plastic, everything — it was never rated for dryers, it's a documented fire risk, and replacing it is urgent rather than optional. Thin foil flex is legal only as a short transition and fails in practice: it crushes when the dryer pushes back, and its ridges hoard lint. The durable setup is rigid metal for the run and a short semi-rigid transition at the machine, and converting yours is quick work.

Yes — reroutes are half this page. A shorter run with fewer elbows dries clothes faster, collects less lint, and needs less frequent cleaning, and sometimes the better route only became possible after a remodel or appliance move. That can include a new exterior penetration, properly flashed and sealed, which as a licensed contractor I do as part of the job rather than around it.

Bad enough to fix promptly. Every load pumps a couple of liters of water into that space as humid air, along with lint — the recipe for condensation, mold, and rot in exactly the framing you least want wet, plus a lint bed near a heat source. The fix is extending the run to a real exterior termination, and it's one of those repairs that costs a little and prevents a category of expensive.

Yes — cutting a new exterior penetration, sealing it properly, and fitting a hooded termination is normal work. The part people get wrong is the seal: a hole cut through siding and left unflashed leaks for years. I flash and caulk it as an exterior job, not a laundry job.
