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 Repair Across Sebastopol
Chimney repair in Sebastopol typically runs $220 – $1,600 depending on whether you’re dealing with flashing, a cracked crown, or mortar failure, and most jobs are completed in a single visit. We work throughout Sebastopol, from the older orchard-era homes off Bodega Avenue to newer construction near the Laguna de Santa Rosa, and we know exactly how these structures hold up to coastal damp and decades of seasonal fires. If you’ve noticed a leak, spalling brick, or a damper that no longer closes, call (830) 251-4560 for a free estimate. A written price comes before any tool leaves the truck. That’s not a courtesy. It’s how we’ve operated since 2002 under The Garrison Standard.
Why Flint Chimney Sweep Is Sebastopol’s Preferred Chimney Repair Company
Sebastopol homeowners call us because we put the entire repair in writing: the price, the scope, the material brands, and a 365-Day Done Right Promise that covers the work for a full year. If a covered repair fails, we return at no charge. No argument, no re-quote. That guarantee is rare in the chimney trade, and it’s the main reason word spreads through neighborhoods like Hessel, the Burbank district, and the streets around Main.
Our technicians are background-checked and uniformed, so when someone arrives at your door, you know who you’re letting in. Every job starts with a camera inspection. You see the problem with your own eyes before approving anything. Our owner, Hank Delano, built the company on that principle: no recommendation without visual proof. That means when we tell a Sebastopol homeowner a liner needs relining or a crown needs rebuilding, they’re looking at the same camera feed we are. The Sebastopol building department keeps its own records on repair permits, and our photo reports give you documentation that survives resale conversations.
We dispatch crews from our San Francisco Bay Area office to serve Sebastopol locally. Response time for most repairs runs three to five business days, and the phone is answered by a live person around the clock.
Chimney Flashing Repair in Sebastopol
Chimney Flashing Repair in Sebastopol addresses the metal barrier where your chimney meets the roofline, and it’s one of the two most common calls we take in this city alongside crown work. Marine-influenced damp means water sits against flashing longer here than in drier inland towns like Windsor or Cotati. When flashing loosens or corrodes, winter rain works its way into the roof deck and down along the flue, rusting the damper and saturating surrounding framing. A standard flashing repair in Sebastopol runs $380 – $750, depending on the roof pitch and whether we’re replacing step flashing, counter flashing, or both.
Signs Your Flashing Has Failed
Stains on the ceiling near the chimney, damp drywall, and a persistent musty smell in the attic are the usual tells. On the roof side, you might see lifted shingles or visible rust at the chimney base. We repair flashing with Copperfield and Olympia Chimney products, cut and sealed to match the existing roof line.
When Flashing Repair Is Enough, and When It Isn’t
If the roof decking under the flashing is solid, a repair is a one-visit job. If water has been tracking for years, we’ll show you the extent with a camera before we quote. We will not propose a tear-out without evidence, and if a repair can safely wait, we say so.
Chimney Crown Repair in Sebastopol
Chimney Crown Repair in Sebastopol means rebuilding or sealing the concrete or mortar slab that caps the top of your chimney and sheds water away from the flue. The crowns on older Sebastopol homes, especially the orchard-era bungalows and mid-century ranches, were often poured too thin, with no expansion joint. Decades of damp, fog, and winter rain crack them. Water seeps in, freezes in the occasional cold snap, and widens the crack. Spalling begins. A crown repair or rebuild in Sebastopol typically runs $500 – $1,100.
Why a Cracked Crown Gets Worse Fast Here
West-facing chimneys near the coastal influence off Bodega Avenue take the worst of it. Fog sits longer, and the wet-dry cycle accelerates deterioration. A small crack this year becomes a spalled, crumbled edge the next.
Repair vs. Rebuild
Minor cracks get a proper crown sealant, applied after cleaning and profiling the surface. A badly deteriorated crown gets demolished and repoured with a proper overhang and a flexible bond break. Both fixes get the same one-year written guarantee.
Mortar Repointing and Tuckpointing in Sebastopol
Older Sebastopol chimneys, particularly those built before modern portland cement mixes, show mortar erosion faster than the brick. Repointing means raking out loose, deteriorating mortar joints and replacing them with fresh material matched in color and hardness to the original. Tuckpointing is a finer cosmetic version of the same craft, used when the joint profile matters as much as the structural integrity. Buying the wrong mortar is the most common cause of repeated failure. We match compressive strength to the existing masonry so new material moves with the old. On a typical Sebastopol chimney, repointing runs $35 – $60 per square foot, and most jobs take a single day.
Spalling Brick and Partial Rebuilding
Spalling happens when water trapped inside the brick freezes and forces the face of the brick off in chips and flakes. On Sebastopol chimneys with a cracked crown and failed flashing, spalling usually shows up on the upper courses within two to three winters. Left alone, the damage deepens into the flue. Partial rebuilding involves removing the compromised sections and replacing them with matched brick and mortar, often paired with a new crown. A partial rebuild in Sebastopol runs $800 – $1,600 depending on how many courses must come out.
Chimney Waterproofing for Damp Winters
Waterproofing is the cheapest underused repair on this page. A vapor-permeable siloxane treatment lets the masonry breathe while shedding bulk water. On a chimney that’s been crown-repaired and repointed, waterproofing adds years before the next cycle of damage begins. In Sebastopol, we recommend it on most exposed brick chimneys, especially those shaded by oak and fir where surfaces stay wet longer. Average cost is $250 – $450, applied in one visit.
Chimney Repair Process: What Actually Happens on a Sebastopol Call
Here’s the sequence, and it never changes. First, we listen. You describe what you’re seeing. Then we run a camera from the top of the flue down through the smoke chamber and into the firebox. You watch that footage. If the chimney needs repair, the evidence is on the screen, not in a sales pitch. If it only needs a sweep, we tell you that. The price you approve before booking is the price on the invoice. There is no re-quote at the door. That’s The Garrison Code in practice: document everything, prove what needs proving, and stand behind the work in writing.
On a call off Bodega Avenue in west Sebastopol, our tech found the chimney crown badly cracked and spalling, with water tracking down the flue liner and a rusted damper below. We rebuilt the crown to shed water, repaired the flashing at the roofline, and ran a camera inspection showing the firebox and smoke chamber were sound. We sent the homeowner a photo report with a flat price agreed before any of the work started. That report went into their file. If they ever sell the house, it’s evidence the chimney was maintained, not just talked about.
Trusted Brands We Service in Sebastopol
We work with professional-grade chimney materials selected by job, not by margin: DuraFlex for relining, HeatShield for parge and repair of flue segments, Gelco for crown sealant, and Copperfield for flashing and caps. Famco and Olympia Chimney products appear in our parts stock when the job calls for them. For Sebastopol customers, stocking common parts locally means a repair quote is backed by material we can actually get on the truck. Fast turnaround isn’t a slogan. It’s a parts inventory.
Common Chimney Repair Problems We See in Sebastopol Homes
- Cracked crowns and failed flashing. Winter rain off the marine layer gets in, rusts the damper, and erodes mortar joints. These two failures appear together more often than not, and they rarely fix themselves.
- Glazed creosote buildup. Sebastopol’s oak and fir canopy means heavy loading, and first-degree creosote overlooked during the busy season can build toward a glazed third-degree layer that only rotary or chemical methods remove. That’s a chimney fire waiting on a spark.
- Debris and animal nests in the flue. Surrounding oak and fir dump leaves, acorns, and twigs directly onto chimney caps and into uncapped flues. Squirrels and birds sense a quiet stack. A blocked flue chokes draft and raises carbon monoxide risk before anyone notices symptoms.
- Spalling brick on the upper courses. Trapped water freezes, and the brick face flakes off in chips. Usually it starts near the crown and works down. Catching it early means repointing and sealing. Catching it late means partial rebuilding.

FAQs About Chimney Repair in Sebastopol
Once a year, at the end of the burning season or right before it, whichever fits your schedule. Sebastopol’s damp winters and heavy tree canopy load flues faster than drier inland areas. A Chimney Inspection - Sebastopol with a camera catches what a visual check misses: cracks in hidden mortar, early stage liner damage, or a nest partway down. If we inspect and find nothing, we tell you that plainly. We don’t manufacture work. Call (830) 251-4560 to book a sweep and inspection at the same visit.
You see the interior of the flue from firebox to crown, in real time, on a screen we bring inside or hold on the roof line so you can view it live. The photo report documents every defect, marked with dates and locations, so you have a record that matters if you sell the house or file an insurance claim. Nothing gets recommended that isn’t on that footage.
Mostly, no, and that’s the point. Leaks show up as stains and damper rust. Drains show up as a burning smell or backdraft. But the early stages of crown cracking, failing flashing, or hidden creosote buildup are invisible from the hearth. That’s why we don’t quote repairs over the phone. We look first, then show you, then quote. If all it needs is a sweep, that’s what you’ll hear.
Yes, and those are the two most common repairs we perform on Sebastopol’s orchard-era bungalows and mid-century ranches. Those older crowns were often poured thin, without expansion joints, and the flashing has had decades of damp exposure. We replace both with current-spec materials from Gelco, Copperfield, and Olympia Chimney, matched to the existing masonry where it shows.
Flashing and crown work usually can if you aren’t burning, but there’s a cost to waiting: Sebastopol’s winter rain will keep working its way in, and next spring’s quote may include damage that didn’t exist this fall. On the other hand, if the issue is purely cosmetic, there’s no reason to rush. We’ll tell you which category you’re in, and we’ll put the recommendation in writing. Call (830) 251-4560 for a free estimate and the straight answer.
