Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Inspection Across Danville
A chimney inspection in Danville typically costs $189 – $389 for a standard Level 1 or Level 2 evaluation, and most Danville homes are scheduled within 3 – 5 business days. We know the housing stock here: custom estates off Blackhawk Drive, semi-custom builds in the Sycamore Valley corridor, older ranch-style properties near Diablo Road. Our Chimney Inspection team has worked these streets long enough to know what the original builders got right and what 40 years of valley heat and cold have quietly undone. Call (336) 863-3889 and we’ll give you a written price before we ever put a ladder against the house.
Why Alcott Chimney Sweep Is Danville’s Preferred Chimney Inspection Company
Ruben Castellano built Alcott Chimney Sweep around a simple standard: you know exactly who’s coming to your door before they arrive. Every Danville customer receives the technician’s name and photo in advance, and that technician arrives in uniform, shows a photo ID badge at the door, and has already passed a background check and identity verification. That’s the Threshold Standard, and it is non-negotiable. For homeowners in Danville who are often home alone, or who have young kids, or who simply want to know who they’re letting inside, that certainty matters as much as the inspection itself.
Our reputation in Danville comes from showing our work. We don’t tell you a flue liner is cracked and ask you to take our word for it. We run the camera, then turn the screen toward you and walk through what we’re seeing. If the liner is fine, we say so. If it’s failing, you’ll see the exact crack, gap, or spall on the footage before any repair conversation starts. That’s why Danville homeowners keep our number, and why we’ve served the area since 2002 as part of the Threshold Group family.
Dispatch for Danville is coordinated from our San Francisco Bay Area office, so scheduling is fast and consistent. You’ll get a live person on the phone at (336) 863-3889 whenever you call, day or night.
Chimney Fire in Danville
Chimney Fire in Danville isn’t a hypothetical. Our inland valley location means overnight lows in the 30s°F all winter, so Danville residents genuinely burn wood, season after season, in ways that coastal Bay Area homes simply don’t. That regular use builds creosote, the tar-like flammable residue that coats flue walls, and creosote is what starts chimney fires. Add the fact that much of Danville sits in a Very High Fire Hazard Severity Zone abutting Mount Diablo State Park, and a clean, properly inspected flue becomes a fire-safety requirement, not a maintenance suggestion.
What We Check During a Fire-Safety Inspection
We inspect the full flue path from firebox to crown, looking for creosote buildup at all three stages: dusty first-degree, flaky second-degree, and the tar-like third-degree glaze that’s especially stubborn. We verify spark arrestor integrity at the top, because a missing or rusted spark arrestor screen can let embers escape onto dry grass and oak woodland. In Danville’s fire-prone setting, that’s a non-negotiable item.
Damage and Deterioration No One Sees From the Ground
Freeze-thaw cycles crack clay tile liners from the inside, and 100°F+ summer weeks bake mortar joints and chimney crowns. We document every gap, cracked tile section, and deteriorated crown surface on camera so you know what’s real and what isn’t. You get a written inspection report, and if we find something that needs attention, you’ll see it before you decide what to do.
Level 2 Chimney Inspection in Danville
A Level 2 Chimney Inspection in Danville includes everything a Level 1 covers, plus the accessible portions of the flue interior, attic, crawlspace, and exterior, and it’s the right call whenever a property changes hands or a chimney has seen years of heavy burning. In Danville, that’s most of the market. Homes in Blackhawk and along Sycamore Valley Road and Diablo Road are commonly 35 to 50 years old, with masonry chimneys built in the 1970s through 1990s, and those flues have been through decades of real winter use. A Level 2 is the only way to know what’s happening inside those older liners.
Real Estate Transactions and Level 2 Requirements
In Danville, a Level 2 inspection is the standard for real estate transfers, and many local agents and home inspectors require it before a sale closes. We serve Danville, San Ramon, Clayton, Alamo, and Dublin agents and buyers with photo-documented Level 2 reports delivered within 48 hours of the inspection. Our written reports match what lenders and insurers in Contra Costa County expect to see.
Camera-First Inspection of Multi-Flue Estates
Blackhawk estates routinely have two, three, or even four fireplaces per property: an indoor living room fireplace, a master bedroom unit, a kitchen hearth, and an outdoor fireplace. We treat each flue as its own inspection. That means running the camera up every single one, because a clean living-room flue tells you nothing about the master suite unit 20 feet away. Our per-property pricing reflects that multi-flue reality instead of pretending a four-flue estate is a single-flue job.
Trusted Brands We Service in Danville
Danville homes carry a range of factory-built and masonry systems, and we service the brands local builders actually specified. We install and repair DuraFlex liner systems, work with HeatShield resurfacing, and service Olympia Chimney and Famco components in zero-clearance units and prefabricated fireplaces across the Danville market. Copperfield dampers and other professional trade parts are stocked on our trucks for faster turnaround, so we’re not waiting on a box-store order while your fireplace sits unusable through a cold Danville winter.
Common Chimney Inspection Problems We See in Danville Homes
- Cracked clay tile liners in 1970s – 1990s masonry chimneys. Danville’s valley pocket traps cold air in winter and bakes in summer heat above 100°F, and that aggressive thermal cycling cracks and spalls clay tile flues faster than in coastal markets. A Level 1 inspection won’t find these gaps; a Level 2 camera run will.
- Degraded zero-clearance fireplaces from 1980s construction. Refractory panels crack, door gaskets flatten, and damper assemblies seize on these units after 35 to 40 years of service. We flag these constantly during routine cleanings in Blackhawk and the custom-home corridors.
- Multi-flue estates treated like single-flue jobs. The master bedroom fireplace or the outdoor kitchen stub gets skipped, and third-degree creosote or a failed crown goes unnoticed. We run the camera up every flue on the property, every time.
- Spark arrestor failure on homes near Mount Diablo State Park. Rusted or missing spark arrestor screens are common on Danville chimneys, and in a Very High Fire Hazard Severity Zone, a missing screen is a real-life ignition risk, not a cosmetic issue.

FAQs About Chimney Inspection in Danville
A Level 1 inspection is appropriate for a chimney that’s been regularly maintained and has no known issues, but in Blackhawk’s multi-flue estate homes built 30 to 50 years ago, we recommend a Level 2 when there’s any history of heavy burning, a real estate transaction, or simply no maintenance record at all. The camera run is the only way to see inside the flue liners, and on a four-fireplace property, every flue deserves its own look. A Level 1 checks what you can see from the accessible areas; a Level 2 tells you what’s actually going on inside 30 feet of clay tile. Call (336) 863-3889 and we’ll talk through which level fits your home.
Most 1980s zero-clearance units in Danville are nearing the end of their useful window for certain components: refractory panels crack from repeated thermal cycling, door gaskets flatten and won’t seal, and damper assemblies corrode. Those issues are structural to the unit’s age, not failures caused by how you use it. We flag them when we see them and document everything on camera, and we’ll tell you plainly what can wait and what can’t. Schedule an inspection at (336) 863-3889 and we’ll show you exactly what’s failing.
An unlined or clay-tile-lined chimney is more vulnerable to the valley’s freeze-thaw winters and 100°F+ summer swings, which cause cracking and spalling that lets heat and combustion gases reach combustible framing. A Level 2 camera inspection is the only reliable way to assess the condition of those tiles, and we’ll show you the footage in real time. If a liner is needed, we install DuraFlex systems with a written price before any work begins. Call (336) 863-3889 for a free estimate.
Yes. Homes in Danville’s Very High Fire Hazard Severity Zone, especially those near the park boundary, should have a Level 1 inspection at minimum once per year, with a Level 2 every three to five years unless a real estate transaction or known issue triggers one sooner. The spark arrestor is the single most important component on your chimney in that setting, and we check it on every visit. If you’re unsure when your last inspection happened, call (336) 863-3889 and we’ll get you on the schedule.
We know because we run a camera up the flue and look at it. Third-degree creosote looks like a glazed, tar-like coating that’s concentrated and difficult to remove, and it’s a fire hazard that builds up over years of burning. You’ll see it on the screen with us, and we’ll document it in the report along with photos. If we tell you it’s present, you’ll see the evidence yourself. Call (336) 863-3889 to schedule a camera-first inspection today.
