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 San Pablo
Air duct repair in San Pablo typically runs between $300 and $1,800 depending on what our camera finds inside your ductwork. Most jobs are done same day once we’re on site. If you’ve noticed weak airflow, sooty streaks near registers, or rooms that never hold temperature, the problem is rarely the furnace itself. It’s the ducts. Call (980) 447-2498 and we’ll send a technician who knows these postwar San Pablo homes inside and out.
We work the neighborhoods along San Pablo Avenue, Rumrill Boulevard, and up through the hills above Contra Costa College every week. We know what original 1950s ductwork looks like when it’s been quietly failing for decades. And we know what it costs to put right, because we’ve done it on hundreds of houses here.
Key Takeaways:
- Whole-system duct repair in San Pablo ranges from $300 for isolated joint sealing to $1,800 for major trunk line replacement.
- Homes here accumulate a fine, oily residue from the refinery corridor that accelerates joint failure in original galvanized ductwork.
- Every repair includes a written guarantee and a free second visit if the fix doesn’t hold. You’ll know the price before we start, always.
- Your technician’s name and photo arrive before the visit. A photo ID badge is shown at the door. No exceptions.

No voicemail loops.
We’ve repaired ducts in postwar tract homes off San Pablo Avenue, in the older bungalow blocks near the Richmond line, and in the hill streets winding up from Emeric Avenue. San Pablo has a specific problem set, and we built our repair process around it.
Duct Replacement in San Pablo
Duct replacement in San Pablo is what we do when the original galvanized trunk lines or branch runs are too far gone to seal back to spec. In these 1940s and 1950s worker homes, much of that original sheet-metal ductwork has been breathing attic air and crawlspace dust for twenty or thirty years without anyone knowing. When we pull a camera through and find crushed sections, disconnected branches, or joints that have rotted open from the oily residue this city is known for, patching won’t hold. Replacement is the honest call, and it runs $800 – $1,800 for most single-story San Pablo homes.
What Replacement Involves
We remove the failed sections, not the whole system unless it’s truly shot. New galvanized or flex runs go in, sized to your blower’s actual CFM, not whatever was lying around in 1955. Then we seal every joint and test static pressure before we leave.
Why Original Ducts Fail Here
The Chevron Richmond Refinery complex sits just upwind. Homes in San Pablo draw in airborne particulates and petroleum byproducts that coat the inside of duct walls with a fine, oily soot. It clings, dries, shrinks, and pulls old lapped joints apart. Cleaning that residue without replacing the failed connections just means recontamination within a season.
Ductwork Installation in San Pablo
Ductwork installation in San Pablo covers homes where the system was never right from the start, or where a remodel or furnace swap changed the airflow demands. We see it constantly in compact postwar floor plans: a return added in the hallway but never balanced, a supply run that dead-ends into a wall chase. New installation for a typical 800 to 1,200 square-foot San Pablo home runs $1,200 – $2,000 when we’re replacing the full trunk and branch layout.
Balancing for These Floor Plans
These homes were built tight and quick for shipyard and refinery workers. Adding central air to them forty years later was often done without proper duct design. We calculate room-by-room CFM, size the runs to match, and cut in returns where the old system starved the blower.
Postwar Attic Constraints
Attic clearances in San Pablo’s 1950s bungalows are low. Our installers work with low-profile transitions and correct hanger spacing so the new ducts don’t sag, crush, or rub against the roof decking. We photograph everything as it goes in.
Trusted Brands We Service in San Pablo
We run professional-grade Rotobrush negative-pressure extraction equipment and Nikro agitation tools on every San Pablo job. For air-quality products, we work with Aprilaire, Abatement Technologies, and Guardsman components. We stock common replacement fittings and sealants locally, so a repair in a Rollingwood bungalow or a tract home off Rumrill doesn’t wait on a warehouse shipment from out of state. If your system already carries one of these brands, we’ll match the existing design and upgrade where it makes sense. 365 days, if the work isn’t right, we make it right, in writing, every time.
Common Air Duct Repair Problems We See in San Pablo Homes
- Oily soot residue from the refinery corridor. The Chevron Richmond plume deposits a fine, tacky film inside ducts that ordinary household dust doesn’t mimic. This residue accelerates galvanized joint corrosion and shows up as dark streaks at supply registers.
- Crushed branch runs in low-clearance attics. Original 1950s sheet-metal runs get stepped on, flattened by stored boxes, or kinked during roofing work. Camera inspection shows the pressure loss clearly.
- Disconnected joints pulling crawlspace air into supply lines. As the oily lining dries and shrinks, lapped seams open. Your blower then draws damp, dirty air from under the house and pushes it through every room.
- Mildew inside dormant winter ducts. San Pablo’s damp, cool winters keep systems idle for months. When summer starts, the first blast of air carries that mildew smell through the house. The fix is not just cleaning. It is repairing the moisture entry points and sealing the runs.

FAQs About Air Duct Repair in San Pablo
San Pablo homes sit downwind of the Chevron Richmond Refinery and the surrounding industrial corridor along the Richmond line. The airborne particulate load here includes fine petroleum byproducts and industrial soot that settle inside duct walls as an oily film. Pinole and El Cerrito don’t get this same plume. That film clings to galvanized metal, dries, shrinks, and pulls old seams apart. So the same 1950s duct material fails noticeably faster in San Pablo. You can call (980) 447-2498 for a camera inspection and written quote.
Most original galvanized trunk lines in these homes can be partially repaired rather than fully replaced. We replace only the failed sections and seal the remaining joints unless the metal is so far gone that sealing won’t hold. The determining factor is how much of the run has opened up and how deeply the oily residue has corroded the seams. We’ll show you the camera footage and give you an honest recommendation and price before any work starts. Call (980) 447-2498 for that assessment.
It’s a combination of petroleum byproducts, industrial particulates, and fine carbon soot from the Chevron Richmond Refinery complex just upwind of San Pablo. Unlike ordinary household dust, it has a slightly tacky, oily quality and clings to galvanized duct walls instead of blowing through. Over time it dries and shrinks, which actively pulls old joints apart. This is the reason our camera inspections in San Pablo homes find more collapsed runs and disconnected branches than in neighboring cities. The fix is mechanical removal with negative-pressure extraction, then repair of the failed connections.
Yes. We check the blower motor amp draw, inspect the air handler cabinet, and test static pressure before and after the repair. A duct system that’s been leaking and pulling attic air for years often shows an overworking blower. Once we seal and replace the failed runs, the amp draw drops back into spec. If the blower or handler needs separate attention, we’ll tell you and give you the written price for that work separately. Call (980) 447-2498 to schedule.
Mold and mildew grow when moisture gets into the ducts and isn’t pulled out. In San Pablo’s damp winter months, leaky joints and disconnected runs let crawlspace humidity seep into the supply side, where it sits during idle periods. We seal every connection, replace rotted or wet insulation, and verify that the repaired system maintains proper airflow through the off season. If you smell that musty odor when the heat kicks on in the fall, call (980) 447-2498. We’ll find the moisture entry point and fix it.
You cannot prevent outdoor air from carrying some particulate load in this part of the East Bay. That’s the reality of living downwind of an active refinery. What you can do is keep the duct system sealed and add proper filtration at the air handler. We install Aprilaire media filters and Abatement Technologies products that capture far more of the incoming particulate than a standard 1-inch fiberglass filter. Combined with sealed ductwork, this dramatically slows recontamination. For an exact recommendation and a written price, call (980) 447-2498.
When your ducts are leaking, crushed, or coated in the residue this city’s air delivers, you need a repair team that understands exactly what’s in those walls. We do. Call (980) 447-2498 now for a free estimate and a repair plan built around your San Pablo home. Written price before any work begins. Written guarantee on every repair. 365 days, if it’s not right, we come back at no charge.
