Dryer Vent Hose Replacement in Laguna Niguel, CA

Do I need a new hose, or is the problem further down the line?

That is the first thing worth settling. The flexible hose behind the machine is a transition connector only. It is not the duct. If your cycles have stretched from 45 minutes to 90-plus, a fresh hose alone rarely fixes it. On second-floor laundry rooms running 18-30 feet vertical to a roof jack, the restriction is usually compacted lint at the base of the rise or a roof cap screen packed with nesting material. We check airflow at the termination before touching anything.

When the hose is the fault, the damage is almost always physical. Shallow condo closets with pedestal washers and dryers crush the foil flat against the demising wall. Four inches of diameter becomes an inch. Vinyl and thin foil kink and tear; UL-listed semi-rigid aluminum holds its shape better. In tight clearances a rigid offset box behind the dryer beats any hose.

Installation details matter. No sheet metal screws through the duct, since they catch lint. Clamps and foil tape, joints aimed with the airflow, slack kept to a minimum.

Short garage-wall sidewall runs in older single-story stock are the easy version. Upstairs long runs with pets or a family of four need a look every six to nine months.
