Dryer Vent Cleaning & Replacement in Los Angeles, CA
Los Angeles housing leans old: the median home here was built around 1964 according to U.S. Census Bureau ACS 5-year (2022) data, and much of the stock runs from 1920s Craftsman and Spanish Colonial Revival bungalows through post-war tract homes and mid-century ranches. Dryer vent runs in houses of that age were often added later, threaded through stucco walls, crawl spaces or attics, and finished with whatever hose was on hand. Long developed lengths, elbows and roof terminations all slow airflow, and slow airflow is what lets lint pack into the duct.

Why dryer vent cleaning is different in Los Angeles
Two Los Angeles conditions shape this work. Along the coast in Venice, Playa del Rey and San Pedro, the persistent marine layer keeps morning air damp and salty, which corrodes exterior metal hardware — including vent hoods and damper flaps that then stick shut and trap moist lint inside the duct. Inland and in the hillsides, autumn Santa Ana winds push dust and debris into vents and ducts, and wildfire risk in the canyon areas makes any unsealed or damaged exterior termination worth checking. On top of that, a large share of older detached garages across the city have been converted to ADUs under California's accessory-dwelling rules, which frequently means dryer vents and ductwork were rerouted — sometimes well, sometimes not.
Problems we fix in Los Angeles
- Foil or plastic flex hose behind the dryer
Thin foil and plastic hose crushes behind the appliance and holds lint in its ridges. The California Fire Code treats lint accumulation as a fire hazard, and this is one of the easiest things to correct during a visit.
- Long runs and roof terminations
In two-story homes and hillside properties, the duct may run the length of an attic to a roof cap. Every added foot and elbow cuts airflow, and the California Mechanical Code sets limits on maximum developed length.
- Corroded or stuck exterior hoods
Salt air in Venice, San Pedro and other coastal areas attacks exterior metal, so damper flaps seize open or shut. A stuck damper either traps lint and moisture or leaves the duct open to pests and wind-driven debris.
- Wind-driven dust and ember intrusion
Santa Ana winds drive dust and debris into vents and flues, and wildfire risk is high in the hillside and canyon areas. A damaged or missing hood on a termination should be replaced rather than screened over, since the Mechanical Code prohibits screens at dryer terminations.
- Improvised ducting after an ADU or garage conversion
Detached-garage ADUs often end up with a dryer in a spot that was never planned for one, and the exhaust gets routed through the nearest available path. These runs are worth inspecting for material, length and where they actually terminate.
- Gas dryer backdraft
A blocked vent on a gas dryer can push combustion byproducts back into the room, a carbon monoxide risk in tight post-war homes and converted spaces. If drying times have crept up on a gas unit, treat it as urgent.
- Shared shafts in condos and apartments
Los Angeles has a heavy condo and multifamily share, and those buildings may have additional shaft and fire-damper requirements. Individual unit ducts tie into building systems, so coordination with the HOA or manager is often part of the job.
What we do
We clean the entire duct from the dryer connection to the exterior termination, not just the first few feet. That matters most on the long attic and roof runs common in older Los Angeles homes.
We measure airflow before and after so you can see whether the blockage was lint, a crushed hose or a stuck exterior damper. It also flags runs that exceed what the California Mechanical Code allows for developed length.
Foil and plastic hose gets replaced with code-appropriate rigid metal duct. This is the fix for ducts that have been crushed behind a dryer or damaged during a garage or ADU conversion.
When a laundry area has moved — a common result of ADU conversions in detached rear garages — we plan a shorter, straighter path with fewer elbows and a proper exterior termination.
Corroded hoods and seized dampers near the coast get swapped for new terminations with a working flap. We seal the wall or roof penetration so wind-driven rain from the November-through-March wet season stays out.
Licensing, permits and codes in California
In California, cleaning alone is generally not treated as contracting work and typically does not require a license. Installing, replacing or rerouting dryer ductwork is construction work and generally requires a contractor licensed by the California Contractors State License Board (CSLB), a board within the California Department of Consumer Affairs, once labor and materials reach the state's threshold — most commonly under a C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) or general building (B) classification. Confirm current requirements with CSLB. Routine cleaning needs no permit, but new or relocated exhaust ducts, new penetrations through exterior walls or roofs, and any associated gas or electrical work typically require a mechanical or building permit from the Los Angeles city or county building department; verify with that department. Work is governed by the California Mechanical Code (Title 24, Part 4) for duct material, maximum developed length, termination and the prohibition on screens at terminations, with the California Residential Code covering routing through concealed spaces.
Timing and availability
Across California, dryer vent demand rises in fall and winter with heavier laundry loads, slower drying and more attention to fire risk, with a second peak during spring cleaning and pre-listing inspections. In Los Angeles specifically, early fall ahead of Santa Ana wind and wildfire season is a sensible time to have exterior terminations checked, and the start of the winter rains is when water intrusion around roof and wall penetrations tends to surface. You do not have to wait for a season: our phones are answered 24/7 at (888) 996-7488, most Los Angeles area requests can be scheduled same-day or next-day, and you get a free estimate before any work begins.

Dryer Vents questions in Los Angeles
How often should a dryer vent be cleaned in Los Angeles?
There is no single interval that fits every home, so go by symptoms: longer drying cycles, a hot laundry room, or lint at the exterior hood. Coastal homes under the marine layer deal with damp morning air that helps lint pack, and hillside homes take in more wind-blown dust during Santa Ana events, so both are worth checking before fall.
I converted my detached garage into an ADU. Can you reroute the dryer vent?
Yes — rerouting ductwork is part of our scope, and it comes up often with the older detached rear garages found in many Los Angeles neighborhoods. Because a new or relocated duct and any new wall or roof penetration typically require a permit and a CSLB-licensed contractor, we will walk through the scope with you and give a free estimate first.
Can you put a screen on the vent to keep embers and pests out?
No. The California Mechanical Code prohibits screens at dryer exhaust terminations because they catch lint and block airflow. The correct approach is an intact exterior hood with a working damper flap, properly sealed where it passes through the wall or roof.
My dryer is gas and clothes are taking two cycles. Is that dangerous?
Restricted exhaust on a gas dryer can cause combustion byproducts to back up into the living space, which is a carbon monoxide concern. Stop using the dryer and call us at (888) 996-7488; we answer 24/7 and can usually get a technician out same-day or next-day.
I live in a condo. Can you still work on my vent?
Often yes, though multifamily buildings may have additional shaft and fire-damper requirements, and HOAs are the norm for condos and hillside gated enclaves in Los Angeles. Check whether your association requires approval or its own vendor before we schedule.
