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 Berkeley, CA
Dryer vent cleaning in Berkeley usually runs $110 to $230 and typically takes about an hour in a standard single-story home. What makes Berkeley different is the housing: most homes here were built before 1960, with vent runs that were retrofitted through tight crawl spaces and aging wall cavities, and the persistent marine fog keeps lint damp and packed rather than dry and loose. If you’ve bought a Craftsman bungalow in the flatlands or a hillside home north of campus and haven’t had the dryer vent checked since moving in, call (806) 606-6902 and we’ll put a written price in front of you before any work begins.
Why Berkeley Homes Are Different
Berkeley’s residential stock is overwhelmingly pre-1950, and that changes duct and vent work in ways you won’t see in Fremont or Dublin. Original sheet-metal ductwork is common in the Craftsman bungalows that line the flatlands from Westbrae to South Berkeley, and much of it was fitted into spaces never designed for forced air. In the hillside Period Revival homes north of campus, access to duct runs often means working through crawl spaces cut into a slope, where clearance is measured in inches rather than feet.
Before any cleaning begins on a pre-1978 home, California asbestos regulations require testing of suspect duct wrap and joint tape. CleanRun’s crews handle that step as standard procedure before touching a run, because what sits inside the wall cavity matters as much as what sits inside the duct. Add Berkeley’s year-round marine fog to aging, poorly sealed ductwork and you get chronic moisture problems: condensation inside runs, mold colonization in the Elmwood and Claremont hills, and return air that smells like a damp crawl space even after new filters. Duct work here isn’t a seasonal task the way it is inland. It’s a condition of the house.
Our Main Berkeley Services
Berkeley homeowners call CleanRun most often about two things: the full air duct system and the HVAC components that move air through it. Both are covered in detail on their own pages.
Air Duct Cleaning in Berkeley
Full-system air duct cleaning for Berkeley’s older homes means documenting what’s inside every run before any tool goes in. In pre-1960 bungalows, that camera feed typically shows decades of accumulated debris: plaster dust from old renovations, pet dander worked into fiberglass liner, and in some cases asbestos-containing tape that must be managed before cleaning proceeds. See Air Duct Cleaning in Berkeley for the full scope, pricing, and what the before-and-after photo record includes.

HVAC Cleaning in Berkeley
HVAC cleaning targets the active components of the system: blower motor, evaporator coil, condensate pan, and the plenum where debris collects before entering the ducts. Berkeley’s elevated humidity means coil fouling happens faster here than inland, which reduces airflow and drives up energy use in homes where the furnace may already be original. The full breakdown is on the HVAC Cleaning in Berkeley page, including what a documented coil cleaning actually entails.

AfterDryer Vent Cleaning in Berkeley

Dryer vent cleaning in Berkeley costs between $110 and $230 for a standard single-story home, and the job usually takes about an hour. In Berkeley’s pre-1960 housing stock, the problem is rarely the lint you can see; it’s the packed accumulation behind the wall, where a 90-degree elbow in a tight crawl space traps moisture and lint together until the vent becomes a fire hazard and a drying-time nightmare. Long vertical runs up the exterior wall of a Berkeley Craftsman are common, and they load differently than short horizontal vents in newer construction. CleanRun’s Dryer Vent Cleaning service documents every foot of the run with before-and-after photos, so you can see exactly what was removed and that the vent is clear to the termination point.
Dryer Vent Inspection
Signs you need it
Clothes take more than one full cycle to dry, or the dryer gets unusually hot to the touch during a normal load.
What it costs in Berkeley
A standalone dryer vent inspection in Berkeley typically runs $110 to $230.
How we do it
We run a camera through the full vent length, measure airflow at the termination point, and hand you a written report with still images of any blockage or damage.
Lint Removal
Signs you need it
Visible lint is escaping around the dryer connection, or the vent flap outside doesn’t open fully during a cycle.
What it costs in Berkeley
Full lint removal from the dryer connection to the exterior termination runs $110 to $230 in Berkeley homes.
How we do it
We use negative-pressure extraction with a rotary brush sized to your vent diameter, then photograph the cleared run end to end.
Bird Guard Installation
Signs you need it
Birds are nesting at the exterior vent termination, or you hear scratching sounds near the laundry wall.
What it costs in Berkeley
Bird guard installation added to a vent cleaning in Berkeley runs $45 to $90 per guard.
How we do it
We remove any nesting material carefully, then fit a galvanized guard over the termination and verify airflow with a meter.
What Dryer Vent Cleaning Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| Dryer vent inspection (standalone) | $110 - $230 |
| Dryer vent cleaning (full run) | $110 - $230 |
| Bird guard installation (per guard) | $45 - $90 |
Multi-story Berkeley homes with vertical vent runs through interior walls can push toward the top of the range because access takes longer and the run itself is longer. The price is written down before any panel comes off, and it doesn’t change unless you approve a change order in writing.
How often should a dryer vent be cleaned in Berkeley?
Every 12 months for most Berkeley households, given the marine humidity that keeps lint damp and prone to packing. Homes with long vertical runs or multiple roommates doing frequent laundry may need it every 8 to 10 months. Call (806) 606-6902 for a written recommendation after an inspection.
Can you clean a dryer vent that runs through a Berkeley crawl space?
Yes, and we do it regularly here. Berkeley’s tight hillside crawl spaces require specialized access techniques, but our documented photo record covers every foot of the run including crawl space sections. Call (806) 606-6902 to schedule an inspection.
Duct Repair & Sealing in Berkeley

Duct repair and sealing in Berkeley typically costs $150 to $900 depending on the size of the leak and the accessibility of the run. In pre-1960 Berkeley homes, the most common problem is not a single dramatic tear but accumulated leakage at every joint and elbow, where old metal ductwork has pulled apart over decades of thermal cycling and hillside settling. Sealing those joints properly, not just taping over them, is the difference between a system that leaks conditioned air into the crawl space and one that delivers it to the register. The full scope is documented in our Duct Repair & Sealing service, including the written photo record of every sealed joint.
Duct Sealing
Signs you need it
Rooms at the end of long duct runs never reach the thermostat temperature, or you feel cold drafts near floor registers when the system is off.
What it costs in Berkeley
Full-system duct sealing in Berkeley typically runs $150 to $450 for an average single-story home.
How we do it
We locate every leak with a pressure test, then seal joints with mastic and reinforce with metal tape where needed.
Flex Duct Repair
Signs you need it
You can see a sagging or kinked flex duct in a crawl space, or airflow to certain rooms has dropped noticeably.
What it costs in Berkeley
Flex duct repair in Berkeley typically costs $250 to $600 per run, depending on length and access.
How we do it
We replace damaged flex with the correct diameter, size the connection properly, and photograph the completed repair.
What Duct Repair & Sealing Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| Duct sealing (full system) | $150 - $450 |
| Flex duct repair (per run) | $250 - $600 |
| Duct insulation (per section) | $15 - $40 |
Berkeley’s hillside homes with difficult crawl space access will tend toward the upper end of these ranges because the technician works in confined conditions that take longer. Every price is written before work starts, with no per-joint surprise charges.
Does duct sealing actually reduce energy bills in Berkeley?
Yes, in most Berkeley homes where duct leakage exceeds the typical 20 to 30 percent. Sealing returns that air to the living space rather than the crawl space or attic, which directly reduces heating and cooling demand. Call (806) 606-6902 for a pressure test and written estimate.
Will you seal ducts in a 1920s Berkeley bungalow without damaging the original construction?
Yes. We work through existing access points wherever possible and use mastic that bonds to old sheet metal without requiring duct replacement. Every opening is documented with before-and-after photos. Call (806) 606-6902 to discuss your specific home.
Air Quality & Sanitizing in Berkeley

Air quality treatment and sanitizing in Berkeley runs $150 to $600 depending on the scope of treatment and whether the system includes UV or purification components. Berkeley’s persistent fog layer keeps interior relative humidity high year-round, which means mold spores and bacteria can establish themselves inside duct runs and return air plenums in ways they simply don’t in drier inland climates. The service isn’t about masking odors; it’s about treating the surfaces where mold lives and preventing recirculation through the system. See Air Quality & Sanitizing for the full procedural breakdown and what the documented treatment record includes.
Mold Treatment
Signs you need it
Musty odor comes through the registers every time the system cycles, or visible mold is present on the inside of the plenum or blower housing.
What it costs in Berkeley
Surface mold treatment in Berkeley ductwork typically costs $300 to $600, depending on the affected area.
How we do it
We photograph the affected surfaces, apply an EPA-registered treatment to all accessible interior duct surfaces, and document the result.
Odor Removal
Signs you need it
A stale or musty smell returns within days of opening windows, even after the house has been aired out.
What it costs in Berkeley
Whole-system odor removal in Berkeley typically runs $150 to $400, depending on square footage and system size.
How we do it
We locate the source with a camera inspection, treat the affected surfaces, and document the treatment before and after.
What Air Quality & Sanitizing Costs in Berkeley
| Item | Typical range in Berkeley |
|---|---|
| Mold treatment (surface) | $300 - $600 |
| Odor removal (whole system) | $150 - $400 |
| UV light installation (per unit) | $350 - $900 |
Homes near the Berkeley waterfront or in the fog-heavy Elmwood and Claremont neighborhoods often need more extensive treatment because the moisture load is higher. The written price includes the documented photo record, so you can see the treated surfaces.
Will sanitizing my ducts get rid of the musty smell in my Berkeley home?
Yes, when the smell originates inside the duct system, which is common in Berkeley’s high-humidity housing stock. If the odor source is outside the ducts, we’ll document what we find and recommend the correct fix. Call (806) 606-6902 for an inspection.
Is the treatment safe for my family and pets?
We use EPA-registered products applied in accordance with manufacturer specifications, and we provide written documentation of what was used. Occupants should vacate during active treatment and for the re-entry period stated on the product label. Call (806) 606-6902 to discuss the specific product before scheduling.
