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.

AfterAir Duct Cleaning in San Leandro, CA
Dryer vent cleaning is the service San Leandro homeowners request most often, and the housing stock explains why. Post-war tract homes in Washington Manor, Broadmoor, and Estudillo Estates were built with short, often poorly routed dryer vents that have now accumulated 40 to 70 years of lint, and the bay-exposed climate compresses that lint with moisture into a dense, stubborn blockage. If your dryer is taking longer than one full cycle to dry a standard load, call (806) 606-6902 and we’ll send a technician with a camera to find out what’s actually inside the run.
Why San Leandro Homes Are Different
San Leandro sits directly along the I-880 corridor, one of California’s highest-volume diesel freight routes connecting the Port of Oakland to distribution hubs south. Homes within a half-mile of the freeway, which bisects the city, collect a distinctive dark diesel soot film on register covers that we rarely see in same-vintage homes in Hayward or San Lorenzo. Combine that with a dense stock of 1950s to 1970s tract homes whose original galvanized sheet metal ducts have rarely been serviced, and the result is an unusually large share of duct systems that are both heavily soiled and structurally aging.
The marine layer complicates things further. San Leandro is one of the more bay-exposed cities in the East Bay, with persistent summer fog and salt-laden air that drives moisture into duct systems through leaky registers and attic runs. That accelerates mold colonization at duct joints and boot connections, a problem more pronounced here than in the drier Tri-Valley cities 20 miles inland. Many original duct runs in Broadmoor and Estudillo Estates also retain early fiberglass duct liner that has deteriorated and is shedding particulate into the air stream.
Our Main San Leandro Services
Two services in San Leandro generate the most calls from homeowners who have researched their options and want a documented result. Both start with a written price before any work begins.
Air Duct Cleaning in San Leandro
Whole-home duct cleaning removes the diesel soot, construction dust, and deteriorated liner particles that accumulate in San Leandro’s original post-war ductwork. We photograph the inside of every duct run before and after, so you can see exactly what was extracted. The freeway proximity means heavier particulate loading than in more set-back East Bay suburbs, and the before/after record is often striking. Learn more about Air Duct Cleaning in San Leandro.
HVAC Cleaning in San Leandro
HVAC cleaning in San Leandro focuses on the blower, coils, and plenum, the components most affected by the salt-laden marine air and the soot film pulled in from I-880 corridor traffic. A fouled coil reduces system efficiency even when ducts look acceptable. We provide a documented photo record of every component we service. Details are on the HVAC Cleaning in San Leandro page.

BeforeAfterDryer Vent Cleaning in San Leandro
Most San Leandro dryer vents in Washington Manor, Broadmoor, and Estudillo Estates branch ran through side walls or crawl spaces when these homes were built between the late 1940s and early 1970s, and many have never been fully cleared. The bay moisture compacts lint into a mat that behaves more like felt than loose fiber, and that restriction forces the dryer to work harder and run hotter. A full Dryer Vent Cleaning restores airflow and gives you a before-and-after photo record of the run.
Dryer Vent Inspection
Signs you need it
Drying cycles exceeding 45 minutes or a burning smell while the dryer runs are the two most common signs we see in San Leandro homes.
What it costs in San Leandro
A dryer vent inspection in San Leandro runs $85 to $150, which includes camera documentation of what we find.
How we do it
We run a camera through the full vent path, photograph every restriction, and hand you a written condition report before recommending any work.
Lint Removal
Signs you need it
Lint visible at the exterior vent cap or a dryer that shuts itself off mid-cycle points to a restriction that needs removal.
What it costs in San Leandro
Full dryer vent lint removal in San Leandro typically runs $120 to $180, depending on the run length and the severity of the blockage.
How we do it
We use a rotary brush and negative-pressure extraction to break up and pull the compacted lint out without pushing it deeper into the run.
What Dryer Vent Cleaning Costs in San Leandro
| Item | Typical range in San Leandro |
|---|---|
| Dryer vent inspection | $85 – $150 |
| Lint removal | $120 – $180 |
| Vent rerouting or bird guard addition | $150 – $300 |
How often should a dryer vent be cleaned in San Leandro?
Every 12 to 18 months for most San Leandro homes, and every 12 months if your vent run is longer than 15 feet or passes through a crawl space. The bay moisture compresses lint faster than in drier inland climates. Call (806) 606-6902 for a written quote.
Do you clean the dryer vent from inside or outside?
Both, as needed. We work from the dryer side and the exterior cap to ensure the entire run is cleared, not just the first few feet. Every job ends with a camera-verified photo record. Call (806) 606-6902 for a quote.
Duct Repair & Sealing in San Leandro
Original galvanized ductwork in San Leandro’s 1950s and 1970s tract homes has had decades to develop leaks at every joint and seam, so conditioned air is being pushed into attics and crawl spaces instead of rooms. The bay’s salt-laden air accelerates corrosion at these gaps, making sealing work in this city less about maintenance and more about recovering lost capacity. Duct Repair & Sealing starts with a camera inspection that shows you every leak before we seal it.
Duct Sealing
Signs you need it
Uneven room temperatures or rooms that never reach the thermostat setting are the most common leak indicators in San Leandro homes.
What it costs in San Leandro
Duct sealing in San Leandro ranges from $350 to $900, depending on how many runs are accessible and how many joints need work.
How we do it
We apply mastic sealant by hand to every accessible joint and seam, then photograph the sealed runs to document coverage.
Flex Duct Repair
Signs you need it
Crushed or sagging flex duct in the attic is common in San Leandro homes where original runs have been disturbed by storage or previous work.
What it costs in San Leandro
Flex duct repair in San Leandro typically runs $200 to $500 per section, including replacement material and reconnection.
How we do it
We cut out the damaged section, splice in new code-compliant flex duct, and seal both connections with mastic and foil tape.
What Duct Repair & Sealing Costs in San Leandro
| Item | Typical range in San Leandro |
|---|---|
| Duct sealing (per run) | $150 – $400 |
| Flex duct repair (per section) | $200 – $500 |
| Full-system sealing | $800 – $1,800 |
How much conditioned air do leaky ducts lose in San Leandro?
Leaky ductwork in this area commonly loses 20 to 35 percent of conditioned air into attics and crawl spaces, especially in original post-war systems with unsealed seams. Sealing returns that air to the rooms you’re paying to heat or cool.
Can you seal ducts in a crawl space without tearing up the floor?
Yes. We access crawl space runs from the crawl side and seal joints with mastic from below, which avoids any floor demolition. A camera record shows every seal after the work is done.
Air Quality & Sanitizing in San Leandro
The combination of I-880 diesel soot, deteriorated fiberglass liner particles, and salt-moisture mold colonization means San Leandro’s indoor air problems have multiple contributors that need addressing together. Cleaning alone removes the loose contamination, but sanitizing is what addresses the biological growth rooted at duct joints and boot connections in bay-exposed homes. Air Quality & Sanitizing applies hospital-grade treatments after a documented cleaning, so the record shows both what was removed and what was treated.
Mold Treatment
Signs you need it
A persistent musty odor when the blower runs, or visible staining around register openings, suggests mold colonization inside the duct system.
What it costs in San Leandro
Mold treatment for duct systems in San Leandro generally runs $500 to $1,500 depending on the affected area and the volume of ductwork.
How we do it
We apply an EPA-registered antimicrobial to the affected surfaces after cleaning, then photograph the treated areas for your record.
Odor Removal
Signs you need it
Cooking, smoke, or pet odors that linger for hours after the source is gone are usually embedded in dust and liner particles inside the ducts.
What it costs in San Leandro
Duct odor removal in San Leandro typically runs $350 to $800, including the cleaning that removes the odor-carrying particulate.
How we do it
We clean the full duct system, then treat with an odor-neutralizing agent that breaks down the remaining volatile compounds inside the runs.
What Air Quality & Sanitizing Costs in San Leandro
| Item | Typical range in San Leandro |
|---|---|
| Mold treatment | $500 – $1,500 |
| Bacteria sanitizing | $350 – $800 |
| Odor removal | $350 – $800 |
Does sanitizing replace duct cleaning, or is it a separate service?
It’s a separate step that follows cleaning. Sanitizing kills biological growth but does not remove the soot and particulate that must be extracted first. We recommend both for San Leandro homes with freeway exposure.
How long does the sanitizing treatment last?
Manufacturer specifications for the antimicrobials we use range from 6 to 12 months of active surface protection, and the photo record documents what was treated on your job. Call (806) 606-6902 for an exact scope for your system.
