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.

AfterFast, Reliable Air Duct Repair Across Sebastopol
Air duct repair in Sebastopol typically runs $340 – $890 for most crawlspace and attic jobs, and the real cost driver here isn’t the repair itself – it’s what the Laguna fog belt does to ductwork over decades. Our crews work in Sebastopol’s older ranch homes every week, tracing disconnected flex runs, patching rusted sheet metal, and sealing joints that have been leaking damp crawlspace air into supply lines since before most of us were born. We know the housing stock here because we’ve been inside enough of it to map the failure patterns. Call (980) 447-2498 for a written quote before any work begins.
Why Linden Air Duct Cleaning Is Sebastopol’s Preferred Air Duct Repair Company
Sebastopol homeowners call us for the same reason they check a contractor’s license before gutting a kitchen: they want to know exactly who’s walking through the door. Every technician we send into Sebastopol homes is background-checked, identity-verified, and photo-badged under the Threshold Standard. Before the visit, you get the tech’s name and photo by text or email. At the door, they show you their ID badge. No mystery vans, no unmarked trucks. That matters in a town where people actually answer their doors.
We also put the price in writing before any work starts. Not an estimate range over the phone that balloons by the end of the appointment – a fixed price for the specific repair, agreed to before we touch a single duct. If a covered repair fails within 365 days, we return and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s included on every repair invoice, in writing. Marcus Veale, who leads our team, set that standard because he got tired of hearing the same story from Sebastopol homeowners who’d been burned by lowball quotes elsewhere.
People in Sebastopol also appreciate that a live human answers our phones. When you call (980) 447-2498 at 9pm with a collapsed return duct pulling musty crawlspace air into your living room, you get a person. Not a voicemail tree. Not a callback queue. Someone who can actually schedule your repair.
Ductwork Installation in Sebastopol
Ductwork Installation in Sebastopol is rarely a luxury upgrade – in this town, it’s usually the corrective for half a century of condensation. We replace original 1950s and 1960s sheet-metal runs that have pinhole-rusted through at the seams, and we replace sagging early flex-duct retrofits that have pulled clean off their collars. The job involves removing the failed section, sizing the replacement to the system’s static pressure, sealing every joint with mastic and mesh (not tape), and re-balancing the affected branch so air actually reaches the farthest register. In Sebastopol’s ranch homes, expect to pay $1,900 – $4,300 for a full trunk-and-branch replacement, depending on run length and crawlspace access. Partial section replacement runs $420 – $980.
Whole-Home Duct Replacement
Some Sebastopol duct systems are past patching. If your 1962 ranch still runs on original galvanized and the camera shows rust perforation in multiple runs, replacing the system costs less per decade than chasing leaks one at a time. We quote the full job before we start, and we don’t switch to time-and-materials halfway through.
Crawlspace Riser and Branch Repair
In Sebastopol’s slab-less older homes, the risers that come up through the floor from the crawlspace fail first. They rust at the floor transition, pull loose at the boot, and siphon damp buggy air into the supply side. We replace these in a single visit most days, and we show you before-and-after photos of the exact runs we touched.
HVAC Duct Installation in Sebastopol
HVAC Duct Installation in Sebastopol often means routing ductwork through homes that were never designed to have central air in the first place. Many of the city’s eco-conscious remodels and alternative-construction homes added HVAC after the original build, which produces branch runs that snake through cramped attics, duck under structural beams, and dead-end in places no standard cleaning access can reach. When a system like that fails, the fix isn’t a cleaning – it’s re-routing the run so it actually flows. We install new flex and rigid duct to the correct diameter for the unit’s CFM, seal every connection with mastic, and leave the run accessible for future maintenance. Budget $2,400 – $5,600 for a full retrofit installation in a Sebastopol home with non-standard routing, with partial branch additions starting around $650.
Replacing Undersized Retrofitted Runs
We see a lot of Sebastopol homes where someone added a room, tapped a new branch off the existing trunk, and undersized the duct to save material. The result: a bedroom that never heats or cools properly and a blower working harder than it should. We cut out the undersized run, install the right diameter, and balance the whole branch for even airflow.
Sealing and Hard-Piping Existing Systems
Sometimes the duct layout is fine and the leakage is the problem. We seal existing runs with mastic and mesh at every joint, hard-pipe the worst sections in corrosive crawlspaces, and pressure-test the system after work. A sealed system in a Sebastopol crawlspace can change indoor humidity meaningfully inside a week.
Trusted Brands We Service in Sebastopol
We’re brand-agnostic on repairs, which means we’ll fix whatever duct system your Sebastopol home actually has – original galvanized, early-generation flex, or newer insulated trunk. We stock common connector sizes, collars, mastic, and mesh locally so we’re not ordering parts from Sacramento mid-job, and we work with air-quality components from Honeywell and Aprilaire when your system needs filtration or humidity control after a repair. Our extraction and cleaning equipment runs on professional-grade Nikro systems, which is a long way from the portable vacuum units some discount cleaners wheel into West County homes. If a repair reveals air-quality issues downstream, we can quote filtration upgrades from Abatement Technologies the same day.
Common Air Duct Repair Problems We See in Sebastopol Homes
- Rusted sheet-metal runs sweating in the fog belt. Sebastopol’s position in the Laguna de Santa Rosa fog belt means crawlspace ducts under 1950s – 1970s ranch homes stay damp year-round. Condensation pinholes rust through the metal at seams, so the supply side leaks raw crawlspace air into the house.
- Disconnected flex-duct collars pulling in harvest dust. Early flex-duct retrofits in apple-boom-era ranches sag and separate at the collar. Through late summer, those open collars act like a lint trap for Gravenstein-harvest organic dust and airborne fungal spores from the orchards ringing the city.
- Crushed runs under foundation retrofits. When Sebastopol homeowners add ductwork to homes that predate central HVAC, the runs often squeeze through spaces too tight for the duct’s diameter. Crushed sections restrict airflow, strain the blower, and eventually tear open at the fold.
- Mildew on inner liners from persistent moisture. We see active mildew on duct liners in Sebastopol at rates noticeably higher than Santa Rosa, seven miles east. It’s not a cleaning-optional cosmetic problem – it’s a biological contamination issue that requires removal or replacement of the affected liner, then sealing the source of moisture.
Pricing for Air Duct Repair in Sebastopol, CA
A typical Air Duct Repair visit in Sebastopol runs $340 – $890 for a targeted fix: a disconnected collar, a short crushed section, a rusted riser, or seam sealing on one branch. Full duct replacement in an older ranch runs $1,900 – $4,300 depending on house size, crawlspace clearance, and whether we’re replacing sheet metal or insulated flex. Retrofit installations in non-standard homes start around $2,400 and can reach $5,600 with multiple access cuts. What we won’t do is quote you a teaser number and then inflate the invoice once the van is on Bodega Avenue. The price we write down before work starts is the price you pay. Call (980) 447-2498 for a free estimate – we’ll walk the crawlspace or attic with you if you want, so you see exactly what we’re pricing.

FAQs About Air Duct Repair in Sebastopol
Because your ducts live in the Laguna de Santa Rosa fog belt. Sebastopol’s position keeps crawlspace humidity measurably higher year-round than Santa Rosa seven miles east, which accelerates mildew colonization, condensation rust, and dust-mite activity inside duct runs. Homes in drier parts of Sonoma County can go years between cleanings; many Sebastopol homes realistically need one every two to three years. If your ducts need cleaning noticeably more often than that, the real issue is probably a repair problem – a disconnected run pulling damp crawlspace air, or rusted seams leaking moisture into the liner. Call us at (980) 447-2498 and we’ll camera-inspect the system to find the source.
We can repair most damage the same day. Our cleaning service includes camera inspection as standard, because you can’t see a disconnected flex collar or a crushed branch run from the register. If we find a repair issue during the clean, we show you the camera footage, write you a fixed price for the repair on the spot, and complete it during the same visit whenever the parts are on the truck. That’s the practical reality in Sebastopol, where so many 1950s and 1960s ranch homes have original or early-retrofit ductwork that hasn’t been opened in decades. If you already know you have a crushed or separated run, tell us when you book and we’ll load the repair parts before we leave the shop.
During Gravenstein apple harvest season, which runs July through August, the working orchards around Sebastopol produce elevated organic dust and airborne fungal spores. If your return-air duct has even a small separation or open collar in the crawlspace, that dust gets pulled directly into the air handler and blown through the house. We notice a predictable late-summer spike in return-air contamination in homes on Sebastopol’s rural residential edges – a seasonal pattern we simply don’t see in Santa Rosa or Petaluma. If your allergies spike in August, have us camera-check the return path. A disconnected return run is the most likely culprit, and it’s usually a one-visit repair.
Yes. Retrofitted and alternative-construction homes in Sebastopol are some of our most common repair calls specifically because the HVAC was added after the original building. Duct runs in these homes often route through tight attic and crawlspace clearances that no one would have designed from scratch, with non-standard branch paths and hard-to-reach access points. Standard NADCA cleaning alone doesn’t solve that. We re-route, re-seal, and re-balance these systems all the time – the repair might mean opening an access panel we can reach, replacing a crushed section, or running a new branch where the old one dead-ends. Call (980) 447-2498 for a camera inspection and a written quote.
A camera inspection settles it in about twenty minutes, but there are signs you can check before we arrive. If certain rooms consistently get weak airflow while others blast, that’s a restriction – a crushed run, a disconnected collar, or a collapsed section. If you smell must or mildew when the blower kicks on, that’s moisture ingress through a failed seam, not accumulated dust. If your cooling bill creeps up every summer while the house feels no cooler, the system is likely pulling damp crawlspace air into the supply side. These are all repair issues a cleaning won’t fix. We camera-inspect every Sebastopol system before quoting any work, and the inspection is part of the free estimate.
