Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why Linden Air Duct Cleaning Is Antioch’s Preferred Air Duct Repair Company
We’ve pulled enough ductwork out of Antioch homes to know exactly what the Delta does to it. The east-side tracts off Lone Tree Way and Hillcrest Avenue were built fast in the 1990s and early 2000s, and a lot of that original builder-grade flex duct is sagging, kinked, or pulling away from its collars right now. Homeowners in the older west-side neighborhoods near G Street and downtown Antioch call us about rigid sheet-metal runs that have developed pinhole leaks and open seams over decades of service.
Every technician from Linden Air Duct Cleaning who comes to an Antioch home has passed a background check and identity verification under the Threshold Standard. Before your visit, you get the tech’s name and photo sent to you. At the door, they show a photo ID badge. You know who’s walking into your house before you unlock the deadbolt. We’ve been doing it this way since 2004, and our Antioch customers tell us it’s the reason they called us instead of a coupon mailer.
We also answer the phone with a living person, day or night. No call trees, no voicemail loops. When you call at 9pm because your duct popped loose and your AC is blowing into the attic, a real human picks up.
Ductwork Repair in Antioch
Ductwork repair in Antioch typically means reconnecting separated flex runs, sealing leaks at collars and plenums, patching holes in rigid sheet-metal, and replacing crushed or collapsed sections. Most Antioch repair jobs run between $220 and $480 depending on how many runs are affected and whether we’re working in a tight attic or a low crawlspace. If you have a home off James Donlon Boulevard or in the neighborhoods around Deer Valley, we’re in that area regularly and know the layouts.
Reconnecting and Sealing Flex Duct
Flex duct separates at the collar when the original zip ties and tape dry out and fail, usually after 20-plus summers of 100-degree attic heat. We cut the failed connection cleanly, refit the flex over the collar, secure it with proper fasteners, and seal it so attic air stops being pulled into your supply runs. This is the single most common repair we do in Antioch’s 1990s and 2000s tracts, and it restores airflow to rooms that have been starved for years.
Patching and Reinforcing Sheet-Metal Ducts
In older Antioch homes, rigid metal ducts in crawlspaces and attics develop leaks at joints and small rust-through holes. We cut out the damaged section and patch with matching gauge metal, then seal the repair with mastic so it stays sealed through heat cycles and vibration. This work often combines with a full-system clean, since open seams have been pulling Delta dust into the airstream the entire time.
Duct Replacement in Antioch
Duct replacement in Antioch means removing runs that are too far gone to repair and installing new, correctly sized and sealed ductwork. Expect to pay $480 to $1,900 or more depending on how many runs we’re replacing, how far they span, and whether access is through a low attic hatch or a crawlspace. If a flex run is crushed flat at a joist bay or the inner liner is torn and shedding fibers into your air, patching it just delays the inevitable. We’ll tell you straight: sometimes replacing the whole run is the cheaper long-term fix than nursing it along repair after repair. That’s what our Air Duct Repair team sees every week out here.
Full Flex Run Replacement
We remove the old flex entirely, install new R-6 or R-8 flex to fit the run, support it properly so it can’t sag or kink, and reconnect it with a sealed, mechanical collar. After installation we verify airflow and temperature at the registers, not just at the air handler. In Antioch’s east-side tracts, this makes a night-and-day difference in back bedrooms that have been hot for a decade.
Hardpipe Conversion for Long Runs
For long main trunk lines that flex was never meant to handle, we sometimes recommend converting to rigid hardpipe with proper insulation. This is more common in homes with extended ranch layouts and long return runs. It reduces static pressure, quiets airflow noise, and holds up better in an attic that hits 130 degrees every August.
Trusted Brands We Service in Antioch
We work on and repair ductwork from every major residential brand you’re likely to have, including systems we service with professional-grade equipment from Rotobrush and Nikro. For air quality components tied into repaired ductwork, we carry and install products from Honeywell, Aprilaire, Guardsman, and Abatement Technologies. We also keep common collar sizes, flex duct, mastic, and sheet-metal fittings stocked on our trucks specifically so Antioch jobs don’t need a second visit from a supply house across the bridge. For more on our approach, see our Air Duct Repair in Antioch hub page.
Common Air Duct Repair Problems We See in Antioch Homes
- Flex duct crushed at joist bays. Builders in the 1990s and 2000s ran flex through tight attic framing, and 20-30 years of thermal cycling plus gravity leaves it flattened. A crushed return run starves the blower and overheats the system.
- The two-tone Delta dust and smoke-soot layer. Pale Delta peat dust builds up in the lower part of the duct; wildfire smoke soot from Spare the Air days forms a darker crust on top. That’s an Antioch fingerprint we don’t see 25 miles west in cooler, coastal cities.
- Disconnected collars on original builder duct. Original zip ties and cheap foil tape fail after two decades in an Antioch attic. The run separates, air dumps into the attic, and rooms get nothing.
- Fiberglass-lined plenum degradation. Older east-side homes with fiberglass-lined plenums shed fibers into the airstream as the lining breaks down. When residents seal windows during Spare the Air stretches, the system pushes smoke-laden air through failing interiors, making it worse.
Pricing for Air Duct Repair in Antioch, CA
For Antioch homes, plan on these ranges: reconnecting and sealing a separated flex run runs $220 to $380; patching holes and open seams in sheet-metal ductwork costs $250 to $520; replacing a crushed or torn flex run runs $480 to $1,200; and a partial duct replacement project covering multiple runs falls between $1,200 and $1,900 or more depending on run length and access. The single biggest factor in Antioch is attic access: a low truss attic off Hillcrest Avenue takes longer than a tall walk-up attic in a 2003 tract home.

FAQs About Air Duct Repair in Antioch
Antioch sits at the eastern edge of the Sacramento-San Joaquin Delta, where afternoon Delta winds funnel fine peat dust, agricultural particulates, and tule marsh debris into homes every day. That debris loads ductwork faster, and combined with 95-105°F summer heat that pushes AC systems to run near-continuously, duct materials age and fail faster than in milder coastal cities. Homes in Antioch run their systems harder and pull dirtier air through them; that’s the short version.
If the flex run is still round, not crushed, and the inner liner is intact, we can resupport, reconnect, and seal it and get many more years of service. If it’s flattened at a joist bay, torn, or shedding liner fibers into the airstream, replacement is the honest fix and usually costs less than repeated patch jobs over time. We’ll show you photos from the camera inspection so you can see exactly what we’re seeing before you decide.
We remove the contaminated duct sections where the soot crust is thickest, clean the remaining runs with negative-pressure extraction and professional agitation equipment from Rotobrush and Nikro, and then seal the system so it can’t keep pulling smoke-laden air in through leaks. The goal is not just to hide the soot but to stop the pathway that deposited it in the first place. Every repair includes that written guarantee, and if a covered repair fails within 365 days, we come back at no charge.
A technician arrives in a marked, clean uniform, shows you a photo ID badge, and walks the system with you before touching anything. We take before photos, identify every separated collar, crushed section, and leaking seam, and give you a written price for the repair. Only after you approve do we start work. Afterward, we take after photos and show you the repaired sections, and we leave the price exactly as written. The whole visit is documented, and the tech’s name and photo were sent to you before they arrived.
Yes. On a 100-degree Antioch day, a return duct pulling attic air instead of house air adds load to the blower, raises static pressure, and starves supply registers. Sealing those leaks restores designed airflow to back bedrooms and reduces the runtime needed to reach your set temperature. It also stops the daily Delta dust conveyor from being pulled into the airstream through gaps in the return side. Call (980) 447-2498 and we’ll give you an honest assessment of what your ducts actually need.
If your Antioch home’s ductwork is showing its age, call Linden Air Duct Cleaning at (980) 447-2498. We’ll get a technician to your door, show you who’s coming before they arrive, and put every repair price in writing before work starts. The two-tone dust is an Antioch thing; so is the fix. Let’s get it done right.
