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.
Fast, Reliable Air Duct Repair Across Orinda
Air duct repair in Orinda runs $280 – $1,450 depending on whether a joint needs resealing, a crushed flex run needs replacing, or an entire section was never connected properly in the first place. We work in Orinda homes every week, and most of what we repair traces back to two things: ground settlement pulling 1950s – 1970s ductwork apart under steep crawl spaces, and wildlife from the Tilden and Briones open space packing nests into disconnected runs. If you’re noticing rooms that never warm up or a dusty smell when the heat kicks on, call us at (980) 447-2498 and we’ll walk you through what we’d look for.
Why Linden Air Duct Cleaning Is Orinda’s Preferred Air Duct Repair Company
Orinda homeowners tend to ask sharper questions than most, and we like that. They want to know who’s coming to the door, what the repair will cost before we start, and what happens if it doesn’t hold. Our answer is the same every time: a background-checked, identity-verified technician whose name and photo you receive before the visit, a written price before any work begins, and a written 365-Day Done Right Promise on every repair. If a covered repair fails within that year, we return and fix it at no charge.
We also know Orinda’s housing stock in a way a general HVAC shop doesn’t. The ranch-style and hillside contemporaries built here between the 1950s and 1970s have ductwork routed through unconditioned crawl spaces on steeply graded lots. That combination creates failure patterns we see repeatedly: sheet-metal joints pulled apart at the seams, flex duct crushed under shifting soil, and return runs open to crawl-space air. Marcus Veale, who leads our repair work, has spent years documenting what Orinda’s pre-1980 ductwork looks like once you get a camera into it. When we tell you a repair is needed, we can usually show you the photo from inside your own system.
Response time to Orinda is straightforward. Scheduling and dispatch are coordinated from the brand’s San Francisco Bay Area office, and our crews serve Orinda locally, so we’re on site for most repair calls within one to three business days. You’ll also get a live person on the phone whenever you call, not a voicemail tree.
Air Duct Replacement in Orinda
Air Duct Replacement in Orinda means pulling out sections of ductwork that are too degraded to seal and running new material in its place. We most often recommend it when original 1950s – 1970s flex runs have absorbed decades of oak pollen and wet-season crawl-space moisture to the point where the inner liner has delaminated. Cleaning alone won’t restore airflow in that condition because the flex itself has failed. A partial replacement for one or two runs in an Orinda crawl space typically costs $1,200 – $3,500 depending on access, run length, and whether the crawl space is tall enough to work in safely.
When Replacement Beats Resealing
If a camera inspection shows the flex liner has collapsed inward, or the outer jacket is torn open in multiple places, sealing won’t hold for long. We replace those sections with new insulated flex and seal the connections at the air handler and at the boot. On Orinda lots with steep grades, we also check whether the replacement run needs additional strapping so ground movement doesn’t crush it again.
What Replacing Ductwork Actually Involves
We remove the failed section, inspect the remaining connected runs for hidden damage, install new flex or sheet-metal duct sized to the system, and seal every joint with mastic. Then we test airflow at the registers and verify there’s no crawl-space air being pulled into the house. The written price covers the full job before we start, and the replacement carries the same 365-Day Done Right Promise as any other repair.
Ductwork Repair in Orinda
Ductwork Repair in Orinda is the sealing and reconnection work that fixes leaks, disconnects, and minor damage without replacing entire runs. Most of the Orinda repairs our Air Duct Repair team performs fall into this category. A typical joint reseal or reconnection runs $280 – $850 per section, and it’s the right fix when the duct material is still sound but the connections have failed. Ground settlement under steeply graded Orinda lots routinely pulls sheet-metal joints apart in unconditioned crawl spaces. The result is supply and return ducts that leak conditioned air into dirt and crawl air rather than into the house.
Sealing Disconnected and Crushed Runs
We camera-inspect the full run before touching anything. When we find a disconnected joint, we clean the mating surfaces, reconnect, and seal with mastic and zip-ties or draw bands depending on the duct type. For a crushed flex section that’s still structurally sound, we may be able to restore the cross-section and re-strap it rather than replace the run.
Crawl-Space Leak Repair
In Orinda’s older homes, return ducts often run directly through dirt crawl spaces, and leaks there pull in whatever is in the crawl air: mold spores from winter moisture, rodent odor, dust. We locate the leaks with a pressure test or visual inspection, seal them, and confirm the system is no longer drawing crawl-space air into the house. This is the single most common repair we do on Orinda systems that have never been professionally inspected.
Trusted Brands We Service in Orinda
We work on systems built with components from trade-standard manufacturers, and we keep stock on hand for the ductwork materials Orinda homes actually use. That includes Rotobrush equipment for source-removal cleaning after a repair and air-quality products from Aprilaire and Guardsman for homeowners who want filtration upgrades once the ductwork is sound. Because we’re servicing Orinda weekly, we don’t have to order basic flex, mastic, strapping, or registers from out of town when you need them. The parts for most repairs are in the truck when we arrive.
Common Air Duct Repair Problems We See in Orinda Homes
- Ground settlement pulling sheet-metal joints apart. Orinda’s steeply graded lots shift with winter rain and summer drought, and that movement works on duct joints in unconditioned crawl spaces. Supply runs leak into the dirt for years before anyone notices the room above never heats properly.
- Squirrel and rat nests inside disconnected flex sections. Homes along the hillside streets bordering Tilden Regional Park and Briones, including off Miner Road and the upper Orinda hills, routinely turn up nests packed into flex duct in crawl spaces. We pull the nesting debris, sanitize, and often find the run was already disconnected before the animals moved in.
- Original flex runs that degraded from decades of moisture. Orinda’s wet winters bring crawl-space humidity into poorly sealed older ductwork, and the flex liners absorb it season after season. The inner liner delaminates, airflow drops, and cleaning can’t fix it. The duct itself has to come out.
- Crushed return and supply runs under settled foundations. In homes built into hillsides, foundation movement can physically collapse a duct run. We find supply branches flattened to half their original diameter, which explains why one room is always 15 degrees colder in winter.

FAQs About Air Duct Repair in Orinda
Because the ductwork in most pre-1980 Orinda homes was installed in unconditioned crawl spaces on steep grades, and ground settlement has physically disconnected or crushed sections of it. Cleaning a disconnected duct just stirs dust into a crawl space. You need the run sealed or replaced first, then cleaning matters. Call (980) 447-2498 for a camera inspection and we’ll show you what’s actually there.
Yes, and it comes down to Orinda’s geography. The town sits in a sheltered valley bowl east of the Caldecott Tunnel, which creates a thermal inversion that traps wildfire smoke far longer than in Oakland or Berkeley. During the 2018 Camp Fire and the 2020 SCU/LNU complexes, Orinda homes took on repeated, severe smoke infiltration that settled deep into ducts. Once smoke particulates sit inside a disconnected or crushed run, they don’t leave until the duct is sealed or replaced and the system is source-removal cleaned.
Mostly squirrel and rat nests packed into disconnected flex sections. Homes off Miner Road and the upper Orinda hills bordering the open space are the worst for it. Animals chew through the flex jacket, the run disconnects, and they build a nest in the dead duct. We pull the nesting debris, sanitize the area, and repair or replace the run. This has to happen before any cleaning, because the contaminant source is the nest itself.
We run a camera through the duct and look at the material. If the metal is sound and joints are simply separated, we seal them. If the flex liner has delaminated, the jacket is torn open, or the run is crushed to less than half its diameter, replacement is the only fix that will hold. We’ll show you the camera footage and explain the recommendation before any work is authorized. Call (980) 447-2498 and we’ll set up an inspection.
Usually, yes. When a supply run is disconnected in the crawl space, the heated air pours into the dirt instead of into the bedroom at the end of that run. We regularly find 15 to 20 degree temperature splits between rooms in Orinda homes where the ductwork has never been inspected. A pressure test or camera run will confirm it. Estimates are free, and you’ll get a written price before we start.
If you’ve been putting off a duct inspection because you don’t want a surprise invoice or a stranger at the door you can’t identify, we’ve built our entire process around answering those two concerns. Call (980) 447-2498 for a free estimate. You’ll know the price before we start, and you’ll know exactly who’s at your door before they ring the bell.
