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.

Why Flint Chimney Sweep Is Atherton’s Preferred Chimney Inspection Company
Atherton homeowners have dealt with enough chimney companies that no-show, move the price at the door, or push a liner replacement the moment they step off the truck. That’s not how we work. Every inspection we perform in Atherton gets a written price before any tools come out, and that number is the number you approve. Our technicians are background-checked and uniformed, so you know exactly who’s walking through your gate on Selby Lane or Park Lane before they arrive.
Flint Chimney Sweep has operated since 2002 as part of the Garrison Partners family of independently owned chimney service companies. We follow The Garrison Standard: price in writing first, scope in writing, and a 365-Day Done Right Promise on every repair. That guarantee is a written one, valid for a full year, and if a covered repair fails inside that period we return at no charge. No argument, no fee.
Response time to Atherton is handled from our San Francisco Bay Area office, with crews dispatched locally so you’re not waiting on someone fighting bridge traffic from another county. When an Atherton homeowner calls about smoke backing up into the house or a strange smell from the firebox, we treat it as a priority inspection, not a sales lead.
For Atherton specifically, we know the housing stock. We know the pre-war ranches along the El Camino corridor and the mid-century builds tucked behind oaks, and we know what fails in those chimneys after decades of wet winters and dry summers. That local knowledge changes what we look for on a Level 2 scan.
Chimney Fire in Atherton
Chimney fire risk in Atherton is something we take seriously because the town’s older fireboxes and flues often hide conditions that make a chimney fire more likely. When you call us for a Chimney Inspection and we find third-degree creosote glaze, a cracked flue liner, or a damper that won’t seat, the priority is preventing exactly that failure. A standard inspection in Atherton runs $189 – $449 depending on what level your home needs, and you’ll see the condition in photos before anyone recommends work.
What we check during every Atherton chimney fire assessment
We inspect the smoke chamber, the flue liner, the crown, and the firebox. First-degree creosote is a light dusting. Third-degree is a hardened glaze that burns at high temperature and cannot be brushed off. A camera scan tells you which one you’re dealing with.
When an Atherton homeowner should act immediately
If you hear a rumble like a freight train, see flames shooting from the top of the chimney, or smell smoke in rooms nowhere near the fireplace, call 911 first. Once the fire department clears the scene, call us. We’ll run a full damage assessment and give you a written repair plan the same visit.
Level 2 Chimney Inspection in Atherton
A Level 2 Chimney Inspection in Atherton is the standard we recommend for most homes here, and it’s the one that actually shows you what’s happening inside the flue. It includes everything in a Level 1 plus a video camera scan of the interior flue, the smoke chamber, and the damper area. In Atherton, where many chimneys were relined decades ago and tree cover never stops pushing debris onto caps and crowns, that camera footage is the only honest way to know if a liner is failing. A Level 2 in Atherton usually runs $329 – $449.
Why older Atherton homes need the camera
A clean firebox tells you nothing about the flue above it. We’ve pulled camera scans on 60-year-old Atherton chimneys that looked swept and ready, only to find spalling brick, a cracked clay liner, or a rusted-out damper hiding behind the smoke shelf. The camera is what separates an opinion from evidence.
What you get after the scan
Every Level 2 inspection ends with a photo report. You see the same images we do, with notes on what’s normal, what’s wearing, and what can wait. No scare tactics, no upsell pressure. Just the condition, documented.
Trusted Brands We Service in Atherton
When an Atherton chimney needs a repair, we install and work with professional-grade products the trade actually trusts, including HeatShield, Gelco, Olympia Chimney, and Famco. If your flue needs a new liner, HeatShield’s cerfractory system is one we specify often because it handles the wet-season moisture cycling Atherton’s older masonry sees every year. We keep common components and parts staged for Bay Area dispatch, which means faster turnaround for Atherton customers who need a cap replaced or a damper swapped before the next cold snap. Every material gets named in your written quote by brand, so you can verify what you’re paying for.
Common Chimney Inspection Problems We See in Atherton Homes
- Cracked flue liners hidden behind a clean firebox: Atherton’s pre-war and mid-century homes often have original clay tile liners that look fine from the hearth but show vertical cracking on camera. A broken liner lets heat and gases reach combustible framing.
- Third-degree creosote glaze from infrequent sweeping: Homes that burn a few fires a season still accumulate creosote, especially with the damp, resinous wood common on the Peninsula. By the time it becomes glaze, brushing won’t remove it.
- Animal intrusion from heavy tree canopy: Atherton’s oaks and dense landscaping mean squirrel and bird nests inside flues are a year-round problem here, not just in fall. A cap is cheap insurance, but only after we confirm the flue is clear.
- Leaking crowns and rusted dampers: Our winter rains find every hairline crack in a chimney crown. Water seeps in, the damper rusts, and the metal swells until it won’t seat. We see this pattern on ranches along El Camino and throughout West Atherton.
We were called to a 1950s ranch on Selby Lane where the homeowner smelled smoke in the attic after a winter fire. Our tech ran a Level 2 camera scan and found third-degree creosote glazing inside a cracked HeatShield flue liner, plus a damper that no longer sealed. We removed the glazed section, installed a new liner, and left a photo report showing the before-and-after of the firebox and smoke chamber. No guesswork, no scare tactics.

FAQs About Chimney Inspection in Atherton
For most Atherton homes, an annual inspection is not a hard requirement, but an inspection every one to two years catches problems before they become expensive. If you burn even a few fires each winter, creosote builds, animals move into an uncapped flue, and water works on the crown year-round. A Level 1 visual once a year, with a Level 2 camera scan every two to three years, fits how most Atherton homeowners actually use their fireplaces. Call (830) 251-4560 and we’ll help you choose the right schedule for your home.
A Level 1 inspection is a visual check of the fireplace, damper, and the parts of the flue we can see without a camera. A Level 2 adds a full video scan of the flue interior, smoke chamber, and damper area. If you have an older Atherton home, are buying or selling, have just had a chimney fire, or have changed fuel sources, a Level 2 is the right call. If the chimney has been inspected recently and nothing has changed, a Level 1 may be enough. Call us and we’ll tell you straight which one fits.
Yes, with a camera scan. First-degree creosote is a flaky dust, second-degree is a harder, tar-like coating, and third-degree is a glazed, hardened layer that looks like black glass. A camera scan shows us exactly which stage you have and how far up the flue it goes. No one can see that with a flashlight from the firebox. When we inspect a chimney in Atherton, we show you the footage and the still photos before we recommend anything.
The National Fire Protection Association standard is to sweep when creosote reaches 1/8 inch of buildup, regardless of time since the last sweep. In practical terms, most Atherton homes that burn regularly need a sweep every one to two years, more often if you burn unseasoned wood or have a stove insert. A standard sweep in Atherton typically runs $189 – $289 depending on the flue’s condition and accessibility. We’ll tell you honestly if a sweep is not needed and save you the call.
Minor wear like a rusting damper or a small crown crack can usually wait until the end of burn season if you’re not using the fireplace. What should not wait: a cracked flue liner, third-degree creosote glaze, or any sign of water infiltration. Those conditions are how chimney fires and structural damage start, and delaying them costs more, not less. When we inspect a chimney in Atherton, our photo report tells you plainly which category you’re in. Call (830) 251-4560 to schedule yours.
If you live in Atherton and want a chimney inspection that ends with a written report, camera evidence, and a straight answer on what needs doing and what can wait, call Flint Chimney Sweep at (830) 251-4560. A live person answers day or night, and every estimate is free.
