Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in San Ramon, CA
Chimney repair in San Ramon usually means one of two things: a prefab metal chimney from the 1980s or 1990s that no longer meets clearance standards, or an open masonry fireplace showing water damage at the crown or flashing. The dry summers and intermittent burn bans shape how creosote forms here – slowly, in cool smoldering fires, often as glazed deposits that a standard brush won’t remove. Homes in Canyon Crest, Twin Creeks, and Dougherty Valley were built across a narrow window, and many still have their original factory chimneys. We stock manufacturer-specific poly brushes and camera gear to service those systems without disassembly. Call (833) 736-8208 when you need a repair-capable sweep, not just a brush.
Why San Ramon Homes Are Different
San Ramon sits inside a high-fire-risk Wildland-Urban Interface zone, and since 2019 the municipal code has required annual chimney cleaning and inspection for any home within the Very High Fire Hazard Severity Zone. That makes a sweep here a code-compliance task as much as a maintenance one. Our technicians check spark arrestors, cap screening, and creosote levels as defensible-space precautions on every visit, because the oak-studded hills and Diablo winds make ember intrusion a real concern.
The housing stock compounds it. Most homes are 1970s through 2000s suburban detached houses in planned developments. The 1990s and 2000s Dougherty Valley build-out produced a steady run of prefab metal chimney systems that need manufacturer-specific cleaning methods, not traditional flue brushing. Many west-side and Dougherty Valley homes still have original 1980s-90s prefab fireplaces with short factory chimneys and tight clearances. Standard brushes don’t fit them. We keep poly brushes sized for those systems and run a camera before we recommend anything, because clearance problems in a prefab can’t be seen from the hearth.
The climate does the rest. Warm, dry summers mean wood burning is seasonal and intermittent. Fall and winter Spare the Air burn bans push homeowners into occasional, short fires. Those fires stay cool and smolder, which is exactly how glazed creosote forms. It’s harder to remove than flaky deposits, and it’s the kind that most often leads to a chimney fire if it’s ignored.

Our Main San Ramon Services
San Ramon homeowners call us most often for two things: a code-required annual sweep with camera inspection, and dryer vent cleaning in homes where the exhaust run is long or hidden behind finished walls. Both are fire-risk services, and both deserve a technician who can repair what they find on the same visit.
Chimney Sweep in San Ramon
A sweep in San Ramon is a WUI safety inspection as much as a cleaning. We remove creosote and soot, then run a chimney camera to check the flue, cap, spark arrestor, and clearances. In Dougherty Valley prefab systems, we use manufacturer-specific poly brushes that won’t scratch the thin metal flue walls. If we find a problem – a cracked crown, failed flashing, a missing spark arrestor – we can quote the repair on the spot and often complete it the same day. Chimney Sweep in San Ramon
Dryer Vent Cleaning in San Ramon
Lint builds up in the vent run, and in San Ramon homes with laundry rooms on the second floor or vents running long distances through walls, that buildup is harder to spot and easier to ignore. We clean the full run from the dryer connection to the exterior termination, check airflow, and replace damaged components with Famco venting parts where needed. It’s a dedicated service, not an add-on. Dryer Vent Cleaning in San Ramon
Chimney Repair in San Ramon
Chimney repair in San Ramon often starts with water. Warm, dry summers followed by occasional winter rain means crowns and flashing take a slow, steady beating without the freeze-thaw cycles other regions get. But the bigger issue is age and clearance. Many homes in Canyon Crest and Twin Creeks have original 1980s-2000s masonry crowns and caps that were built to older standards. In Dougherty Valley, we see prefab factory chimneys with failed panels, rusted chase tops, and clearances that don’t meet current code. The work is site-specific: sometimes it’s a cap replacement, sometimes a liner, sometimes both. We stock Gelco, Olympia Chimney, and Copperfield parts locally, and we repair what we find, not just what’s easy to reach. For more on how we approach full-system work, see Chimney Repair.
Chimney Cap Installation
Signs you need it
The cap is missing, rusted through, or no longer covers the full flue opening, leaving the chimney open to embers, rain, and birds.
What it costs in San Ramon
Typical cap installation in San Ramon runs $180 to $450 depending on the flue size and whether it’s a standard single-flue cap or a custom chase-top cover.
How we do it
We measure the flue and surrounding crown, select a Gelco or Copperfield cap sized for the existing chase, secure it with mechanical fasteners, and verify the spark-arrestor mesh meets WUI requirements.
Chimney Cap Replacement
Signs you need it
The existing cap has broken screening, corrosion, or a gap at the base that lets embers and rain slip through.
What it costs in San Ramon
A cap replacement in San Ramon typically runs $140 to $400 including removal of the old cap and disposal.
How we do it
We remove the old cap, inspect the exposed flue and crown, and install a new cap with screened sides and a solid lid sized to the existing termination.
Chimney Liner Installation
Signs you need it
The liner has cracked tiles, gaps in the mortar joints, or pitting visible on camera, or the home is being converted to a gas appliance that requires a different flue size.
What it costs in San Ramon
Full liner installation in San Ramon typically runs $2,200 to $5,800 depending on length, diameter, and whether it’s a flexible or rigid system.
How we do it
We camera the flue, size the liner to the appliance and chase dimensions, lower a professional-grade liner such as Olympia Chimney or DuraFlex into place, insulate where required, and reconnect the appliance.
Chimney Flashing Repair
Signs you need it
The ceiling or walls around the fireplace show water staining, or the existing flashing is lifting, cracked, or no longer sealed at the roofline.
What it costs in San Ramon
Flashing repair in San Ramon typically runs $350 to $1,200 depending on roof access, the number of flashing planes, and whether shingles or tiles have to be lifted.
How we do it
We inspect the full flashing plane, remove failed sealant, refit or replace the step and counter flashing, and seal with a high-temperature roofing adhesive matched to the existing roof material.
Chimney Crown Repair
Signs you need it
The concrete crown has visible cracks, spalling, or water pooling around the flue tile, or the interior shows water damage near the firebox.
What it costs in San Ramon
Crown repair in San Ramon typically runs $250 to $900 depending on whether it’s a resurfacing job or a full recast.
How we do it
We clean the existing crown, fill cracks with a flexible crown sealant, and where the crown is too far gone, we form and pour a new one with a proper slope and a drip edge.
What Chimney Repair Costs in San Ramon
| Item | Typical range in San Ramon |
|---|---|
| Chimney cap replacement | $140 – $400 |
| Chimney crown repair | $250 – $900 |
| Flashing repair | $350 – $1,200 |
Does a cracked crown really matter in San Ramon’s mild climate?
Yes. Even without freeze-thaw, a cracked crown channels rain into the masonry and down the flue. That water eventually reaches the firebox and can delaminate a prefab panel or rust a steel liner. The repair is cheaper before the water stains show on the wall.
Will one visit tell me everything that’s wrong?
Yes. Every San Ramon chimney camera inspection includes the full flue, the smoke shelf, the cap, the crown, and the flashing. We repair what we find, and if the damage is outside our scope, we tell you exactly what to do next. Call (833) 736-8208 for an estimate.

What San Ramon Customers Say
"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
- Danielle Doyle"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
- Ramon Hernandez"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
- Nathan Thompson
