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 Sweep Across Danville
Most Danville chimneys need a sweep every 12 to 24 months, and the work itself usually takes 45 to 90 minutes per flue. A standard chimney cleaning in Danville runs $189 – $289 before any repairs, and we give you that number in writing before a brush touches your firebox. Our crews know the Danville housing stock well: Blackhawk estates with four flues, 1980s zero-clearance units off Camino Tassajara, and masonry stacks in the Sycamore neighborhoods near downtown. If you’ve been putting off a sweep because you don’t want a contractor inventing problems, that’s exactly the situation we built this company to fix. Call (336) 863-3889 and we’ll talk through what you’re seeing, free.
Why Alcott Chimney Sweep Is Danville’s Preferred Chimney Sweep Company
Ruben Castellano founded Alcott Chimney Sweep in 2002, and the standard he set hasn’t changed since: show the homeowner the evidence before recommending any repair. In Danville, where older custom homes and 1980s zero-clearance fireboxes are the norm, that camera-first approach matters more than anywhere else we work. A sweep who tells you the liner is cracked without letting you see it is asking for trust he hasn’t earned. We don’t do that.
Every technician who arrives at a Danville door is background-checked and identity-verified under the Threshold Standard. You’ll get the technician’s name and photo before the visit, and they’ll show a photo ID badge at the door. No exceptions. That’s a concrete answer for people who are home alone, parents with young kids, and older homeowners who want to know who’s coming before the truck pulls up.
Our Chimney Sweep team serves Danville from the brand’s San Francisco Bay Area office, with crews dispatched locally throughout the week. When a Danville customer calls about a smoky fireplace in November, we know what they’re describing: a cold-weather burn season that starts early in this valley and runs hard through February.
Chimney Cleaning in Danville
Chimney cleaning in Danville means removing the creosote and soot that build up inside your flue during burn season, and in this valley, there’s more of it than most Bay Area homeowners expect. Because Danville sits in a pocket off Mount Diablo where winter nights routinely drop into the 30s°F without any coastal marine layer to soften them, fireplaces here get burned consistently. That’s not a guess. It’s what we see in flues across Blackhawk, Greenbrook, and the older streets off Danville Boulevard: genuine second-degree creosote, the tar-like buildup that can fuel a chimney fire.
What a Standard Sweep Includes
A standard sweep in Danville runs $189 – $289 and covers the flue brush, the firebox, the smoke chamber, and the damper area. We lay drop cloths, run a HEPA-filtered vacuum, and leave your hearth cleaner than we found it. The whole job typically takes under two hours for a single flue.
Annual Sweeps for Danville Homes
We recommend an annual sweep for Danville homes that burn more than a cord or two of wood a season, which is common here. For lighter use, every other year is usually enough. The deciding factor is creosote thickness, and we’ll measure it and show you the numbers during the visit.
Fireplace Cleaning in Danville
Fireplace cleaning in Danville is about more than brushing the flue. It means cleaning out the firebox, checking the refractory panels, gaskets, and damper assembly on zero-clearance units, and making sure the whole system vents correctly. In Danville, where many homes were built between the late 1970s and 1990s and still run their original prefabricated fireplaces, those components are now 35 to 50 years old. They degrade. We catch it early.
Zero-Clearance Firebox Service
The 1980s zero-clearance fireplaces across Danville are a recurring service issue. Refractory panels crack, door gaskets dry out, and damper assemblies seize. A sweep that only brushes the flue never sees these problems, and the unit keeps degrading until it fails. We inspect the firebox as part of every cleaning and flag what’s failing, with photos you can see yourself.
Open Hearth and Insert Cleaning
For masonry fireplaces and inserts, fireplace cleaning means removing ash, soot, and creosote from the firebox and smoke shelf, then confirming the damper opens and closes properly. We service both wood-burning and gas-log setups, including the venting they rely on.
Common Chimney Sweep Problems We See in Danville Homes
- Second-degree creosote in hard-burning flues. Danville’s cold valley winters push fireplaces into regular use, and we routinely see thick, flaky creosote that’s a genuine chimney fire risk. This is exactly the material that annual sweeping removes before it becomes a problem.
- Cracked refractory panels in 1980s zero-clearance units. Homes built in Blackhawk and along the Camino Tassajara corridor often still have their original prefabricated fireplaces. Those panels, gaskets, and dampers are at or past their service life, and they’re frequently flagged during routine cleanings.
- Dried-out mortar joints and cracked crowns from hot, dry summers. Danville’s summer heat exceeding 100°F bakes chimney crowns and mortar, opening paths for water. A sweep that only brushes the flue never sees the crown or cap, so the real damage stays hidden above the roofline.
- Cold-air downdrafts on valley floor homes. Danville’s location traps cold air in winter, and older unlined chimneys draft poorly on the coldest nights. We diagnose draft issues during the sweep and can quote repairs only after you’ve watched the camera footage.
Trusted Brands We Service in Danville
We work with the professional trade materials Danville homeowners should be getting. That means HeatShield resurfacing for deteriorating flues, Gelco chimney caps and dampers, and Olympia Chimney components for liner and venting work. If you have a prefabricated fireplace from a brand like Famco or Copperfield, we stock local replacement parts for Danville jobs, so we’re not waiting on a warehouse across the country to get your fireplace running again. When we quote a repair, we tell you the exact brand and product going in, and why it’s the right one for your chimney.

FAQs About Chimney Sweep in Danville
Yes. We routinely sweep multiple flues in a single Danville visit, and Blackhawk estates with three or four fireplaces are a standard job for us. We schedule the extra time up front, quote a per-flue price in writing, and work through each system the same day. Call (336) 863-3889 with the number of fireplaces and we’ll give you a firm quote before we arrive.
No, not always. If you burn less than a cord a season and your flue shows only light first-degree creosote, every two years is often enough. What matters is the measured buildup, not a calendar rule. In Danville specifically, the cold winter nights mean even “occasional” burners often burn more than they think, so we check and show you the actual numbers before recommending a schedule.
First-degree creosote is a fine, dusty soot that brushes off easily. Third-degree is a hard, glazed, tar-like coating that requires chemical treatment or specialized removal and is the most dangerous form for chimney fires. Danville’s consistent winter burning habits mean we see second-degree buildup often, which is exactly the stage where annual sweeping prevents it from hardening into third-degree. We’ll show you which one you have on camera.
The refractory panels inside the firebox, the door gaskets, and the damper assembly. On 1980s zero-clearance fireplaces, these components are now 35 to 50 years old and degrade silently. A sweep that only cleans the flue misses them entirely. We inspect the firebox on every Danville visit and photograph any cracks or seal failures so you can see exactly what’s failing.
Because you should see the evidence before anyone recommends a repair. In Danville, where older custom homes and multi-flue estates make repair quotes larger, the industry’s worst upselling happens when a sweep claims a cracked liner or third-degree creosote and the homeowner has no way to verify it. We run a camera down the flue, show you the footage on a monitor in real time, and only then quote a repair. If we can’t show it to you, we don’t recommend it.
