Question 1

My laundry is on a back service porch in a 1910s bungalow — where does the vent actually go?

Accepted Answer

In most Pasadena Craftsmans and Foursquares, laundry ended up on a rear service porch or in a back hall, and the dryer vent was added long after the house was built. That usually means a short run punched straight through the stucco to a cap low on the exterior wall, or a longer run dropped into the crawl space and brought out at the back or side of the foundation. We trace the duct from the dryer before we clean so we know which it is — the crawl space runs are the ones that surprise people, because they can be longer and sag between supports, and that sag collects lint you'd never see from inside.

Question 2

Why does my vent cap keep clogging when I clean the lint trap every load?

Accepted Answer

Because the problem usually isn't coming from inside. Wall caps near grade are the standard setup on older Pasadena homes, and that puts the opening right where oak and sycamore leaf litter piles up in fall, where Santa Ana dust blows down off the foothills, and where spring pollen settles. The flap gets propped open or packed shut, airflow drops, and lint that used to blow clear starts stacking up inside the last few feet of duct. Cleaning the trap doesn't touch any of that. The cap and the exterior end of the run need attention on their own schedule.

Question 3

What does a cleaning here cost compared to a newer house?

Accepted Answer

It depends mostly on how the vent was retrofit. A ranch in the flats with a straight, accessible run through a side wall is the simple end. An older bungalow where the duct goes under the floor, turns a couple of times, and exits at a low foundation cap takes longer — we're working from both ends, sometimes from the crawl space, and the access alone adds time. Thick stucco penetrations and caps that have been painted over or screened off can add a step too. We look at the run and tell you what it involves before we start, so nothing on the invoice is a surprise.

Question 4

Can you come out the same day?

Accepted Answer

Sometimes, depending on where we already are in the San Gabriel Valley that day. Same-day is most realistic for straightforward jobs where the vent is reachable from outside. If your dryer has stopped drying entirely or you're smelling something hot, say so when you call — that moves you up. If it turns out the run is under the house or needs the cap replaced, we may need to come back with the right parts rather than rush it.

Question 5

What usually fails on Pasadena vent systems?

Accepted Answer

Three things come up repeatedly. First, crushed or disconnected duct in crawl spaces, where flexible pipe was run decades ago and has since sagged, pulled loose at a joint, or been stepped on by someone working under the house. Second, wall caps at or near grade that have lost their flap or rusted shut, which is what the leaf and dust load does to them over time. Third, retrofit penetrations through thick stucco where the duct was never properly sealed, so the gap fills with debris and sometimes becomes a way in for pests. We check all three as part of the cleaning rather than just running a brush through.
