Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Ashby Chimney San Jose Is Fremont’s Preferred Chimney Sweep Company
Nathan Corliss has built Ashby Chimney San Jose around a simple idea that Fremont homeowners seem to appreciate: say the price, show up when you said you would, put the guarantee in writing. That’s the Kingswell Way, and it’s why our reviews from Fremont customers consistently mention the same three things: the phone was answered by a person, the technician arrived inside the window, and the invoice matched the quote. We don’t ask you to trust us on faith. Every job starts with a written price. Every repair ends with a written guarantee that covers the work for a full year, and if a covered repair fails inside that period, our 365-Day Done Right Promise means we return and fix it at no charge.
Being part of the Kingswell network of independently owned chimney companies also means our Fremont customers get something most independents can’t offer: access to professional-grade materials from trusted chimney-trade brands, including DuraFlex, Copperfield, and Famco. Not whatever happened to be on the truck. Dispatch and scheduling are coordinated from the brand’s San Francisco Bay Area office, and crews serve Fremont locally. When we schedule a sweep in Fremont, the technician who arrives is background-checked and uniformed, so you know exactly who’s walking into your home.

Chimney Services in Fremont
Chimney services in Fremont break down into three practical jobs for most homeowners: a routine sweep, a camera inspection, and repair work on whatever the camera finds. In Fremont specifically, the inspection matters more than in many nearby cities because so many homes were built between 1950 and 1980 with unlined or poorly lined masonry chimneys. A standard Level 1 inspection runs $129 to $199 in Fremont. A Level 2 inspection, which includes a camera scan of the flue, runs $249 to $399 and is what we recommend before installing a wood stove or burning in a fireplace that hasn’t been used in years.
Sweeping and Creosote Removal
Creosote is the tar-like byproduct of wood combustion, and it builds up differently depending on how you burn. In Fremont’s mild marine climate, many people burn only on cold winter nights, which means lower-temperature fires that produce wetter, stickier creosote. We remove it with rotary brushes sized to your flue, then vacuum the smoke chamber and firebox so the job is clean top to bottom.
Level 1 and Level 2 Inspection
A Level 1 inspection covers what we can see without a camera: the accessible parts of the flue, the damper, the smoke chamber, and the firebox. A Level 2 goes deeper, with a camera that can show us what’s behind the smoke chamber walls of an older Fremont chimney. If animals have nested in an unused fireplace, or if a liner has cracked, that’s where we find it.

Chimney Sweep Certified in Fremont
Chimney sweep certified work in Fremont means the technician has passed industry-standard training and follows a written inspection protocol on every visit. It’s not just running a brush up the flue. It’s knowing what to look for in a 1960s ranch home near Mission San Jose with an unlined chimney, versus a 1990s Warm Springs house with a factory-built metal flue. In Fremont, chimney sweep certified service costs between $189 and $329 for a standard fireplace, and the certification matters because it means we follow a checklist and document what we find.
Wood Stove Cleaning
Homes in the Niles hills and other Fremont neighborhoods where wood stoves are primary heat sources need a different approach. These units load the flue with creosote far faster than an open fireplace, especially when the stove was retrofitted into an older masonry chimney that never had a proper liner. We clean wood stove flues from the appliance up, and we check the stovepipe joints and the cap as part of the sweep.
Annual Maintenance
An annual sweep is the minimum for any fireplace that gets regular use in Fremont, and for wood stoves we recommend sweeping every cord and a half of wood burned. The cool, damp Bay Area air that moves through Fremont in winter tends to make creosote crust and harden faster than in drier inland cities. Skipping a year isn’t worth the risk, especially on an older chimney without a liner.
Trusted Brands We Service in Fremont
When we repair a Fremont chimney, we use materials from established chimney-trade brands because the parts matter. DuraFlex liners are our go-to for relining older masonry chimneys in Fremont, HeatShield is what we use for resurfacing smoke chambers and flue tiles, and Copperfield and Famco supply the dampers, caps, and flashings we install across Fremont homes. We keep common replacement parts stocked for Fremont jobs, which means faster turnaround when a damper fails or a cap needs replacing. If you want to know exactly what’s going into your chimney, ask the technician. We’ll show you the parts and explain why we chose them.
Common Chimney Sweep Problems We See in Fremont Homes
- Unlined or poorly lined masonry chimneys. In Fremont’s Niles and Centerville neighborhoods, many original chimneys from the 1950s through 1980s were built without proper flue liners. Even light use of a retrofitted wood stove can push creosote into the gaps and create a fire risk that younger housing stock in nearby cities doesn’t have.
- Animal nests in unused fireplaces. Fremont has an older housing stock with plenty of fireplaces that haven’t been used in decades. Birds, squirrels, and rodents move in through broken or missing dampers, and their nesting material blocks the flue and creates a serious fire hazard on first burn.
- Third-degree creosote hidden behind smoke chamber walls. A standard sweep removes creosote from the flue itself, but older Fremont chimneys can hide hard, glazed creosote behind the smoke chamber walls. That’s a glaze that requires chemical treatment or mechanical removal, and it’s exactly why we recommend a camera inspection on older homes before burning season.
- Spalling brick and efflorescence from damp Bay Area air. Fremont’s marine-influenced climate means cool, moist air works its way into original brick chimneys. Over time, the bricks spall, the mortar crumbles, and white efflorescence appears. If flashing repairs are ignored, moisture gets into the firebox and accelerates the damage.

Add a Level 1 inspection for $129 to $199, or a Level 2 camera inspection for $249 to $399. What moves the price: the height and pitch of the roof, the amount of creosote buildup, whether animals have nested, and whether the chimney needs a liner or damper repair that the sweep uncovers.

FAQs About Chimney Sweep in Fremont
Even if you only burn on cold nights, you need your wood stove chimney swept at least once a year, and ideally once per cord and a half of wood burned. Cold-night burning in Fremont tends to produce low-temperature fires, which leave more creosote behind, not less. If your stove is connected to an older unlined masonry chimney in Niles or Centerville, we recommend a camera inspection with every sweep to check what’s accumulating behind the smoke chamber. Call (669) 266-5073 for an exact quote, estimates are free.
Most homes built in Fremont in 1965 had masonry chimneys without proper flue liners, so yes, you almost certainly need a liner before connecting a wood stove. A wood stove produces hotter, more concentrated exhaust than an open fireplace, and pushing that through an unlined or cracked chimney is a fire risk. We recently swept a wood stove in a ranch-style home near Mission San Jose where the flue liner had heavy second-degree creosote and the damper was rusted open, allowing damp Bay Area air to speed up buildup. Our tech replaced the damper, swept the smoke chamber, and installed a DuraFlex liner to bring the old masonry chimney up to safe operating condition for the homeowner’s winter burning habits. Call (669) 266-5073 and we’ll camera-inspect your chimney and tell you plainly what it needs.
Yes. Homes in the Niles hills sit in cooler, damper microclimates than the flatlands, and wood stoves up there often run as primary heat, not occasional supplement. That means heavier creosote loading, a shorter safe sweeping interval, and more risk of third-degree glazed creosote that a standard brush can’t remove. Homes in the Niles hills also tend to be older, with unlined masonry chimneys that trap creosote behind smoke chamber walls. If you burn regularly in the Niles hills, budget for two sweeps a year until we see what your flue actually accumulates. Call (669) 266-5073 and we’ll schedule the first one.
If you hear animals in your Fremont chimney during spring, don’t light a fire and don’t try to smoke them out. Call us for a Level 2 inspection so we can see what’s in there and what condition the flue is in. In older Fremont neighborhoods like Niles and Centerville, we regularly find bird and rodent nests in unused fireplaces, often because the damper was never repaired. We’ll remove the nest, clean the flue, and install a proper chimney cap so the problem doesn’t repeat. Call (669) 266-5073 and we’ll get you on the schedule.
Yes, and it does. Fremont’s marine-influenced climate means cool, moist air works its way into original brick chimneys, especially homes built between the 1950s and 1980s. The bricks absorb moisture and spall, the mortar joints crumble, and white efflorescence appears on the exterior. Once the flashing around the roofline fails, moisture gets into the firebox and accelerates the damage. The fix is repointing the brick, replacing the flashing, and sometimes sealing the crown, and it’s far cheaper to catch that in a Level 2 inspection than to rebuild a chimney later. Call (669) 266-5073 for an evaluation.
