Why Danville Homeowners Choose Hearthstone Chimney Co.
We’ve been sweeping chimneys across the East Bay for over 42 years, and Danville has been part of our route since 2014. In that time, we’ve cleaned flues in the hillside estates of Blackhawk, the ranch-style homes near Sycamore Valley Road, and the custom builds tucked into the Alamo Creek corridor. Homeowners here don’t call us for flash. They call because their neighbor mentioned we returned three times to make a crown repair right under our 90-Day Done Right Promise, no paperwork, no arguing.
Our technicians are background-checked and uniformed. They carry professional-grade materials from DuraFlex, HeatShield, and Copperfield, not whatever was on sale at the supply house. Every Level-2 camera inspection ends with photos you can see on the screen and a plain-English verdict, documented like an engineer, explained like a craftsman. The price we quote is the price on the invoice. We’ve been burned by contractors before too, and we built this company to be the one you don’t have to worry about.
Calls come through to a live person 24 hours a day, 7 days a week. Not a callback queue. Not an app. A human being who can put you on the calendar.
Chimney Cleaning Services We Offer in Danville
Chimney Cleaning & Sweep
Our standard sweep removes creosote, soot, and debris from the flue, smoke chamber, and firebox, followed by a Level-1 inspection. In Danville’s 94506 and 94526 ZIP codes, we regularly find flues that haven’t been touched since the Clinton administration, especially in homes where wood-burning was converted to gas logs and the original masonry was forgotten. Learn more about our Chimney Cleaning & Sweep in Danville.
Chimney Repair
We rebuild crowns, repoint mortar, and repair firebox brickwork using professional-grade materials from Gelco and Olympia Chimney. Danville’s clay tile liners from the 1980s and 1990s are aging out now, and we’ve replaced dozens in the Blackhawk area where thermal cycling cracked the flue tiles beyond repair. Learn more about our Chimney Repair in Danville.
Fireplace Services
Gas log insert conversions, pilot light troubleshooting, and fireplace door installation for the masonry units common in Danville’s late-century custom homes. We also inspect the original firebox and flue after conversion, because the gas insert doesn’t protect the masonry from moisture and temperature swings. Learn more about our Fireplace Services in Danville.
Chimney Cap & Crown Installation
Custom and standard caps in stainless steel and copper, plus poured concrete crown rebuilds with proper drip edges and slope. On Danville hillside properties in the Very High Fire Hazard Severity Zone, we install compliant spark arrestor screens that meet California code, something many homeowners in the 94506 hills don’t realize they lack until we show them the photo. Learn more about our Chimney Cap & Crown in Danville.
Chimney Liner & Rebuild
Stainless steel relining with DuraFlex and HeatShield cerfractory resurfacing for deteriorated clay tile flues. In Danville’s large estate homes with multiple fireplaces, we often find original liners that have exceeded their 30-40 year service life and are spalling clay into the flue. Learn more about our Chimney Liner & Rebuild in Danville.
Neighborhoods We Serve in Danville
We work across both Danville ZIP codes, with same-day or next-day availability for most cleaning appointments. These are the areas we know best:

- Sycamore Valley - Ranch and split-level homes from the 1970s-80s with single masonry chimneys showing age-related crown and mortar deterioration

Most of Danville sits within 15 minutes of our dispatch, and we schedule arrival windows we actually keep.
Why Danville’s Climate & Housing Affect Chimney Cleaning
Danville sits deep in the San Ramon Valley, shielded from the marine layer by the Berkeley-Oakland Hills. That geography produces colder winter nights and more consistent below-40°F mornings than coastal Bay Area cities like Berkeley or Oakland. The temperature differential drives real fireplace use here, not just the occasional decorative burn, and real use means meaningful creosote accumulation rather than cosmetic sooting. We’ve measured glazed creosote buildup in Danville flues that would pass for clean in fog-bound coastal towns.
The housing stock compounds the issue. Blackhawk’s estate-sized homes, built primarily in the 1980s and 1990s, routinely feature two to four masonry fireplaces per property. Many were converted to gas log inserts during the 2000s, and the original wood-burning flues have sat exposed to weather and condensation for 15-20 years with no professional attention. Owners assumed that stopping wood burning meant stopping maintenance. The clay tile liners are now approaching or exceeding their 30-40 year service life, and the combination of age, moisture, and thermal cycling produces spalling, cracking, and liner collapse that a standard sweep alone cannot address.
Diablo wind events funnel through the valley and can reverse chimney draft, pushing combustion byproducts back into living spaces. In these conditions, flue integrity and cap condition aren’t maintenance niceties. They’re functional necessities. We’ve responded to calls from Danville homeowners who smelled smoke in their bedrooms during a wind event, only to find a missing cap and a blocked flue that should have been caught years earlier.

FAQs About Chimney Cleaning in Danville
A standard chimney sweep with Level-1 inspection in Danville typically costs between $189 and $249, depending on accessibility and the condition of the flue. Level-2 camera inspections, which we recommend for homes that haven’t been professionally inspected in over five years, run $289 to $349. Call (844) 803-1545 for a free estimate specific to your chimney.
The National Fire Protection Association recommends annual inspection, with cleaning as needed based on use and fuel type. In Danville, we find that homeowners with active wood-burning fireplaces need sweeping every 1-2 cord burned, while gas log insert owners often need inspection more frequently than they expect because the original masonry continues to degrade even when not in active use. If you’re in a Blackhawk estate home with multiple fireplaces that were converted to gas 15-20 years ago, we strongly recommend a Level-2 inspection to assess the condition of flues that may have been neglected since conversion.
Yes, and this is one of the most common misconceptions we encounter in Danville. Gas logs burn cleaner than wood, but the original masonry firebox, flue liner, and cap remain exposed to moisture, temperature cycling, and corrosion. We’ve removed bird nests, deteriorated clay liner fragments, and corrosion debris from “gas only” chimneys in the Alamo Creek area that had not been inspected in over a decade. The gas insert does not protect the chimney structure. It merely changes what’s burning at the bottom.
A spark arrestor is a mesh screen installed on the chimney cap that prevents embers from escaping onto combustible roofing or into wildland. California law mandates compliant spark arrestors on all chimneys within Very High Fire Hazard Severity Zones, which includes Danville’s hillside properties near Mount Diablo and Las Trampas. In the 94506 hills, we routinely find screens that are corroded through or missing entirely, often because previous owners or contractors removed them without informing the current owner that state law requires them. During your inspection, we’ll photograph your cap and show you exactly what you have.
We answer calls with a live person 24 hours a day, 7 days a week, and we maintain same-day and next-day availability for most Danville appointments. True emergencies, smoke backing up into the home, strong odors indicating a blocked flue, or visible chimney damage after a wind event, get priority dispatch. Call (844) 803-1545 and we’ll tell you honestly whether you need immediate service or can safely wait for a scheduled appointment.
