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.
Air Duct Cleaning in Fremont, CA
Dryer vent cleaning in Fremont is not a luxury add-on. It’s the first thing we recommend to homeowners in Centerville, Irvington, and Warm Springs who bought a 1960s or 1970s tract home and have never once had the dryer vent looked at. Fremont’s housing stock carries 40 to 60 year old vent runs, and the Niles Canyon wind corridor pushes lint, dust, and wildfire ash into those runs faster than most homeowners realize. Call (806) 606-6902 and we’ll give you a written price before any work starts.
Why Fremont Homes Are Different
Fremont consolidated five communities at incorporation in 1956, then grew explosively through the 1960s and 1980s. That left a massive inventory of single-story ranch and split-level tract homes in Centerville, Irvington, and Warm Springs, many still running original ductwork. We routinely see fiberglass duct board that has started to delaminate, early flex duct with sagging runs, and plenums wrapped in materials that have to be identified before we touch them.
The city sits at the mouth of Niles Canyon, and that is the detail that changes the work. The canyon is a natural wind corridor funneling Central Valley particulates into Fremont’s air. When the 2020 SCU Lightning Complex fire burned through the Diablo Range directly above eastern Fremont, ash and smoke particulate entered thousands of duct systems and never left. Residents changed filters. The ash layer inside the ducts stayed. Western Fremont neighborhoods near the bay run under a persistent marine layer that introduces moisture into ductwork, which promotes mold growth inside lined ducts. Warm Springs and Mission San Jose sit 8 to 12 degrees hotter than the bay side and take the brunt of the dry, particulate-laden wind. Same city, two different sets of problems.
Our Main Fremont Services
Most Fremont homeowners call us for two reasons: they want the ducts cleaned properly, or they want the HVAC system cleaned thoroughly. Both jobs start with a written price and end with a documented photo record of every duct run.
Air Duct Cleaning in Fremont
Older Fremont homes often have ductwork that has not been opened since installation. We run a camera through every run before we touch anything, photograph what we find, then clean with negative-pressure extraction so debris does not blow back into the house. In Irvington and Mission San Jose hillside homes, we commonly find smoke-event particulate embedded in duct lining from the 2020 SCU Lightning Complex fire. See Air Duct Cleaning in Fremont for the full scope, including pricing specific to Fremont’s housing stock.

HVAC Cleaning in Fremont
Furnace and coil cleaning in Fremont means dealing with what the Niles Canyon wind deposits inside the system. Blower wheels coated in fine particulates lose airflow, and evaporator coils in bay-side homes grow biological material in the marine moisture. We clean the entire air path, not just the registers. See HVAC Cleaning in Fremont for what the job involves and what it costs in Fremont.

AfterDryer Vent Cleaning in Fremont

Dryer vent cleaning in Fremont is the service we recommend first for owners of 1960s through 1980s tract homes in Centerville, Irvington, and Warm Springs. Those vent runs are decades old, often longer than they should be, and the Niles Canyon wind loads them with lint and fine particulate at a rate that surprises people. We hold no urgency theatre and no per-vent pricing; everything we do is covered by the documented photo record and the written quote that comes before any work. This is the work described on our dedicated Dryer Vent Cleaning page, and the Fremont pricing table is below.
Dryer Vent Inspection
Signs you need it
Clothes take longer than 45 minutes to dry, the dryer is hot to the touch, or you can smell a musty odor near the dryer.
What it costs in Fremont
Dryer vent inspection in Fremont typically runs $125 to $275, depending on access and whether we also clear the vent during the same visit.
How we do it
We run a camera from the dryer connection through the full vent run, measure airflow, and photograph every section before recommending any work.
Vent Cleaning
Signs you need it
The vent flapper outside does not open when the dryer runs, or you see lint accumulating around the exterior vent opening.
What it costs in Fremont
Dryer vent cleaning in Fremont ranges from $135 to $275, based on vent length, access, blockages, and whether it is a single or multi-story home.
How we do it
We remove the lint from the full run with rotary brushes and compressed air, then finish with negative-pressure extraction so dislodged debris does not stay in the wall cavity.
Lint Removal
Signs you need it
The dryer is warm but the clothes stay damp, or the dryer shuts itself down before a cycle finishes.
What it costs in Fremont
Lint removal in Fremont falls between $135 and $225, depending on where the blockage is located and whether it is a roof or wall vent.
How we do it
We locate the blockage with the camera, break up the lint pack with a rotating brush or air whip, and pull it back to the collection point without leaving debris in the run.
Vent Rerouting
Signs you need it
The existing vent run exceeds 25 feet, has more than two elbows, or passes through an unconditioned space that causes condensation inside the pipe.
What it costs in Fremont
Vent rerouting in Fremont ranges from $450 to $900, depending on the new route length, wall type, and whether roof or wall access is required.
How we do it
We design a shorter, straighter route within manufacturer spec, install rigid metal duct, and document the full new run with camera before sealing and testing.
Bird Guard Installation
Signs you need it
You hear birds or scratching near the vent opening, or you can see nesting material around the exterior vent cap.
What it costs in Fremont
Bird guard installation in Fremont typically runs $120 to $250, depending on roof or wall access and the type of vent cap you have.
How we do it
We install a louvered metal guard with a fine mesh that keeps birds out and keeps airflow within manufacturer spec, then photograph the completed installation.
What Dryer Vent Cleaning Costs in Fremont
| Item | Typical range in Fremont |
|---|---|
| Dryer vent inspection | $125 - $275 |
| Dryer vent cleaning | $135 - $275 |
| Lint removal | $135 - $225 |
The dominant price variable in Fremont is roof versus wall venting. Many Irvington and Mission San Jose hillside homes have roof vents that require ladder work and a longer run; bay-side homes in Centerville typically vent through the wall and cost less.
How often should I clean my dryer vent in Fremont?
Every 12 to 18 months for a household of three or more. Fremont’s Niles Canyon winds add particulate load, so we lean toward annual for inland homes.
Can you tell me if my Fremont dryer vent is already blocked?
Yes. We run a camera through the full run before recommending anything and show you the footage along with a written price for the fix.
Duct Repair & Sealing in Fremont

Fremont tract homes from the 1960s and 1970s were built with materials that age poorly: fiberglass duct board that develops pinholes, early flex duct that tears at joints, and metal runs that lose their seal over time. Sealing and repair stops the pulled air that heats or cools your attic and delivers the air you paid for back into the rooms. Every repair is photographed before and after, and the written price is in your hand before anything comes apart. This is the work described on our dedicated Duct Repair & Sealing page, and the Fremont pricing table is below.
Duct Sealing
Signs you need it
Some rooms never reach the thermostat set point, the HVAC runs long cycles, or you see dust trails around registers.
What it costs in Fremont
Duct sealing in Fremont typically runs $350 to $900, depending on the number of runs and whether we need to open the ceiling or wall cavities.
How we do it
We seal joints and seams with mastic or metal tape rated for HVAC use, then pressure-test the system to confirm the leakage rate before and after.
Flex Duct Repair
Signs you need it
You see sagging flex ducts in the attic, or the air pressure at some registers is noticeably weaker than at others.
What it costs in Fremont
Flex duct repair in Fremont ranges from $250 to $800, based on the number of damaged sections and whether they can be reconnected or need replacement.
How we do it
We cut out the damaged section, install new flex duct with proper tension and support, and photograph the repair before sealing the joints.
Metal Duct Repair
Signs you need it
You hear a banging or popping sound when the system starts or stops, or you see rust or corrosion on visible ductwork.
What it costs in Fremont
Metal duct repair in Fremont typically runs $350 to $900, depending on whether it is patching, re-sleeving, or replacing a section.
How we do it
We cut and fit replacement sheet metal, seal seams with mastic, and wrap repairs in insulation where the run passes through unconditioned space.
Duct Insulation
Signs you need it
Ducts run through a hot attic or cold crawlspace and the delivered air is the wrong temperature, or you see condensation on the duct exterior.
What it costs in Fremont
Duct insulation in Fremont runs $400 to $1,000, depending on the length of exposed runs and the R-value we install.
How we do it
We wrap the runs in fiberglass or foil-faced insulation per code, seal the seams, and photograph the finished work before testing airflow.
Mastic Sealant
Signs you need it
You see visible gaps at duct joints, or you can feel conditioned air escaping in the attic or crawlspace.
What it costs in Fremont
Mastic sealant application in Fremont ranges from $250 to $700, depending on how many joints we brush and how much access is needed.
How we do it
We brush on fiber-reinforced mastic at every accessible joint, let it cure, and then document the work so you can see exactly what was sealed.
What Duct Repair & Sealing Costs in Fremont
| Item | Typical range in Fremont |
|---|---|
| Duct sealing | $350 - $900 |
| Flex duct repair | $250 - $800 |
| Metal duct repair | $350 - $900 |
Access is the biggest pricing variable in Fremont: attic work in single-story ranch homes runs lower than crawlspace work in split-levels, and any run embedded in slab foundation pushes the number up.
Will sealing my Fremont ducts actually make a difference in my energy bill?
Yes. Sealed ducts stop the air you paid to condition from leaking into the attic or crawlspace, which reduces system runtime and evens out room temperatures.
Do I have to replace all my ductwork at once?
No. We repair and seal the damaged runs first and recommend replacement only where the duct has structurally failed or is too damaged to seal.
Air Quality & Sanitizing in Fremont

Fremont’s split climate means the same city produces two different indoor air problems: moisture-loving biological growth on the bay side, and smoke-event particulate and fine dust on the inland side of Niles Canyon. When we sanitize a system, we are treating what is actually in the ducts, not generating vague reassurances. Every job includes a before-and-after photo record of the treated surfaces, and the written price is delivered before any work begins. This is the work described on our dedicated Air Quality & Sanitizing page, and the Fremont pricing table is below.
Mold Treatment
Signs you need it
You see dark staining on registers or duct lining, or you smell a persistent musty odor when the HVAC runs.
What it costs in Fremont
Mold treatment in Fremont typically runs $500 to $1,200, depending on the affected area and whether the duct lining must be replaced or can be treated in place.
How we do it
We treat the affected surfaces with an EPA-registered product appropriate for the material, photograph the before and after, and provide a written record of what was applied.
Bacteria Sanitizing
Signs you need it
Someone in the household has recurring respiratory irritation, or the system has a stale odor that does not clear after filter changes.
What it costs in Fremont
Bacteria sanitizing in Fremont ranges from $300 to $700, depending on the size of the system and the number of surfaces treated.
How we do it
We fog the duct system with a product rated for bacterial decontamination, then ventilate the space and document the application in writing.
Odor Removal
Signs you need it
The house smells different when the system runs than when it is off, or odors from cooking or pets persist in certain rooms.
What it costs in Fremont
Odor removal in Fremont runs $300 to $700, depending on the source and whether it is a surface treatment or a full-system fog.
How we do it
We find the source first, then treat the duct surfaces with the appropriate odor-neutralizing product and photograph the treated areas.
UV Light Installation
Signs you need it
You have a coil that keeps developing biological growth, or you live on the bay side of Fremont where marine moisture creates recurring coil issues.
What it costs in Fremont
UV light installation in Fremont ranges from $450 to $950, including the unit, wiring, and coil placement.
How we do it
We mount the UV light at the coil, wire it correctly, and photograph the installation so you can verify placement and operation.
Air Purifier Install
Signs you need it
You want whole-house filtration for Fremont’s wildfire particulate or pollen seasons, or you have a household member with allergies.
What it costs in Fremont
Air purifier installation in Fremont typically runs $500 to $1,200, depending on the unit and whether it integrates into the existing duct system.
How we do it
We install the purifier in the supply or return plenum, wire it correctly, and document the installation with photos and a written scope.
What Air Quality & Sanitizing Costs in Fremont
| Item | Typical range in Fremont |
|---|---|
| Mold treatment | $500 - $1,200 |
| Bacteria sanitizing | $300 - $700 |
| Odor removal | $300 - $700 |
The cost driver in Fremont is which side of the city you live on: bay-side homes with recurring coil moisture tend to need more surface treatment, while inland homes accumulate more particulate that needs physical removal first.
Will air quality treatment fix every odor in my Fremont home?
It treats what is inside the duct system. If the source is elsewhere, we will tell you that directly and recommend the right fix for that source.
Do I need air quality treatment after the SCU Lightning Complex fire?
If your home is in the Irvington or Mission San Jose hills, likely yes. We routinely find smoke-event particulate embedded in duct lining from August 2020, and it does not leave on its own.
