Dryer vent installation in Los Angeles, Orange County, and Ventura County runs $149–450 total depending on vent run length, number of bends, and whether we need to create a new exterior wall penetration. A short straight run through an existing exterior wall is $149–220. A longer run through walls or ceiling with multiple bends and a new stucco penetration is $320–450. About 30% of our calls turn out to be minor adjustments or reconnections on the lower end. This page explains exactly what affects the price.

Why Proper Dryer Vent Installation Matters
This isn't a cosmetic job. A dryer vent installed incorrectly — using flexible foil duct, running too long, exhausting into an attic or wall cavity — is a fire hazard and will cause your LG dryer to fail prematurely. We've seen dryers in Pasadena and Glendale displaying d80 and d90 Flow Sense error codes from day one because the vent was installed incorrectly when the dryer was set up. The dryer was new. The vent was the problem.
California building code requires dryer vents to use rigid or semi-rigid metal duct, exhaust directly to the exterior, and stay within maximum equivalent length limits based on the number of bends. Poor venting causes thermal fuse failures, stresses heating elements, and in coastal areas like Torrance where humidity is higher, accelerates lint buildup throughout the duct run. We install to code on every job and test airflow before we leave.
What Affects the Price
Each foot of rigid metal duct, fitting, and labor adds to the total. Beyond the first 10 feet, extended ductwork runs cost $12–18 per linear foot. California code allows a maximum equivalent length of 35 feet, reduced for each bend. Longer runs may require larger diameter duct or a booster fan — booster fan installation adds $150–200. Most homeowners underestimate the run length when the laundry room is far from an exterior wall — we measure the actual route before quoting.
Every bend reduces airflow efficiency. A vent run with three 90-degree bends has an equivalent length 15 feet longer than its actual length. In townhouses and condos in Irvine and Burbank where the laundry is interior, routing to the nearest exterior wall often requires bends through wall cavities. We design the route to minimize bends while still reaching the exterior efficiently.
Creating a new exit point requires cutting a 4.25-inch opening through the wall and installing a weatherproof exterior vent cap with a damper. Most LA and Orange County homes have stucco exteriors which requires core drilling — that's included in the cost above. We patch and seal cleanly around the new opening. If an existing penetration is in the right location, we use it and the cost stays lower.
Standard wood frame construction in most LA and Orange County homes allows straightforward installation. Concrete block or brick requires specialized drilling. Attic or crawl space routing — common in Malibu hillside homes and older Pasadena properties — adds access time and safety equipment requirements. A simple Burbank garage installation costs less than routing through multiple floors in a Beverly Hills condo. We tell you which category your job falls into when you describe your setup on the phone.
We find improper installations constantly across all three counties — particularly in older homes and apartments where the original setup cut corners. Most common violations: flexible foil duct (fire hazard, traps lint at every ridge), vent exhausting into attic instead of exterior (moisture damage, code violation), and runs that are too long for the number of bends. Replacement is priced the same as new installation — we remove the old material and install properly from scratch.
What Proper Installation Includes
Rigid metal duct throughout — 4-inch diameter minimum per code. Semi-rigid aluminum acceptable in the transition section directly behind the dryer. No flexible foil, no plastic.
Correct exterior vent cap — weatherproof, with a backdraft damper that opens when the dryer runs and closes when it doesn't, keeping birds and rodents out of the duct.
Proper support and securing — duct supported every 4 feet, joints sealed with foil tape (not screws, which catch lint and create blockages).
Airflow test after installation — we run the dryer and measure airflow at the exterior cap. On LG dryers, this means confirming no d80/d90/d95 codes and feeling strong airflow at the exterior vent. We don't call the job done until the numbers confirm it.
Code compliance — we install to California mechanical code. Documentation available if needed for building inspection or HOA.
When Proper Venting Prevents Expensive Repairs
Poor dryer venting is the most common root cause of thermal fuse failures and heating element stress. A dryer that runs with restricted exhaust overheats on every cycle — the thermal fuse eventually blows, and you're paying $280–350 for the fuse plus the vent cleaning that should have been done first. If the vent was improperly installed from the start, the fuse will blow again in weeks for the same reason.
Proper vent installation extends dryer life by reducing thermal stress on every heat cycle. The investment typically recovers its cost through avoided repairs and reduced energy bills. If your LG dryer has been showing d80, d90, or d95 codes, addressing the vent system is the fix — not the dryer itself.
Cost Summary
Short straight run through existing exterior wall: $149–220
Medium run with 1–2 bends through existing exit: $220–320
Long run or new stucco wall penetration: $320–450
Booster fan for runs over 35 equivalent feet: add $150–200

Questions About Dryer Vent Installation Cost
How much does dryer vent installation cost in Los Angeles?
$149–450 total depending on run length, number of bends, and whether a new wall penetration is needed. Short straight run through an existing exit: $149–220. Longer run with new stucco penetration: $320–450. We give you an exact quote after assessing the route — the $65 assessment fee is waived when you approve the installation.
What factors increase dryer vent installation costs?
Run length beyond 10 feet ($12–18 per additional foot), each additional bend, new exterior wall penetration through stucco ($100–150), difficult wall materials like concrete or brick ($50–100 additional), and routing through attics or crawl spaces ($80–150 additional). We tell you exactly which factors apply to your job before we start.
Can I use flexible foil duct for my dryer vent?
No — and we won't install it. California code and LG's installation specs require rigid or semi-rigid metal duct. Flexible foil traps lint at every ridge, crushes and kinks, and is a fire hazard. If your current installation uses foil duct, we replace it with rigid metal.
My LG dryer shows d80 or d90 — is it the vent installation?
Very likely, especially if it's been showing these codes since installation or since you moved the dryer. d80 means 80% airflow restriction. We assess whether it's a blockage or an installation problem and fix it at the same visit. See our LG dryer Flow Sense error page for the full breakdown.
How long does dryer vent installation take?
Short straight run through existing exit: 1–2 hours. Medium run with bends: 2–3 hours. Long run or new stucco wall penetration: 3–4 hours. Attic routing: 4–6 hours. We give you a time estimate when we assess the job.
Do I need a permit for dryer vent installation in Los Angeles?
For simple replacement with the same routing, typically no permit required. For new construction or significant rerouting through walls or ceilings, requirements vary by city and HOA. We advise on your specific situation during the assessment.
