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 Larkspur’s Preferred Chimney Repair Company
We’ve been doing this since 2002 as part of the Garrison Partners family of independently owned chimney service companies, and the biggest complaint we hear from Larkspur homeowners is the same one: a company showed up, found “more work,” and suddenly the invoice doubled. That doesn’t happen here. Every repair we do in Larkspur starts with a written price, and that number is the number you approve and the number you pay. No discoveries that become surprise line items.
Our technicians are background-checked, uniformed, and dispatched on every call, so the person at your door on East Baltimore Avenue or near Larkspur Plaza Drive is the person we said we’d send. We don’t use subcontractors. We carry professional-grade materials including DuraFlex, HeatShield, and Copperfield, specified by what the job needs, not by margin. And if a covered repair fails within one full year, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s printed on every work order. Hank Delano runs our crew, and he holds every tech to the same standard: show up inside the window, do the work right, leave the property clean.
Chimney Repair Companies in Larkspur
Chimney Repair Companies in Larkspur fall into two groups: the ones that push a full rebuild the minute they see a crack, and the ones that tell you what’s genuinely urgent and what can wait. We’re the second kind. A proper chimney repair in Larkspur means fixing what’s broken, waterproofing what’s exposed, and leaving the masonry, flashing, damper, and liner working the way they should. The most common jobs we quote in Larkspur are crown repair, flashing replacement, mortar repointing, and flue liner work.
Repairs We Quote Most Often
On Larkspur’s older homes, especially in the flats and the hillside streets around Baltimore Canyon, we see crowns that have cracked from 30-plus inches of annual rain and flashing that’s pulling away from the roofline. A crown repair runs $350 to $900. Flashing replacement runs $450 to $1,200. If the mortar joints have eroded, we repoint and tuckpoint at $40 to $70 per square foot. Each quote is a fixed number, written down before work begins.
What a Repair Visit Looks Like
We show up, inspect what you’ve flagged, and run a camera up the flue if we think water or draft problems go deeper. Then you get a written quote. You approve it, we repair it, and the guarantee is valid for one full year. No pressure to decide on the spot, and no jump from estimate to invoice.
Chimney Masonry Repair in Larkspur
Chimney Masonry Repair in Larkspur usually means fixing the bricks, mortar, and crown that sit above your roofline, where Marin County’s wet winters do the most damage. Water gets into small cracks, freezes on cold nights, and expands. Over a few seasons, that’s how bricks spall (flake and crumble), mortar joints open up, and a chimney starts leaning. The repair itself runs $400 to $3,500 in Larkspur depending on how much masonry has failed and whether we’re rebuilding a section or the whole stack.
Spalling Brick and Mortar Repointing
We see spalling brick on Larkspur chimneys all the time, especially on the older masonry stacks near downtown and along Madrone Avenue. Individual brick replacement runs $25 to $50 per brick including labor. Full repointing, where we grind out the old mortar and pack in new, runs $40 to $70 per square foot. It’s not cosmetic. Open joints let water into the smoke chamber, and once water is inside, the damage accelerates.
Waterproofing and Flashing Repair
Chimney waterproofing in Larkspur runs $300 to $700 and uses a breathable sealant that keeps water out without trapping moisture inside the brick. Flashing repair, where the chimney meets the roof, runs $450 to $1,200. In Larkspur’s wet climate, flashing is often the first thing to fail on a chimney that otherwise looks fine. A rusted cap or corroded flashing means water tracking down the flue and into the attic, and we’d rather catch that in September than in February.
Trusted Brands We Service in Larkspur
We work with DuraFlex, HeatShield, and Copperfield systems because they hold up in Larkspur’s damp, salt-tinged air and because we can stand behind them for a full year. DuraFlex liners handle the high-heat, high-moisture conditions of older flues. HeatShield is what we use to resurface a cracked clay tile liner without a full rebuild. Copperfield makes caps and dampers that resist the corrosion we see on homes closer to the bay. We keep common parts stocked locally for Larkspur jobs, which means less waiting and fewer return trips.
Common Chimney Repair Problems We See in Larkspur Homes
- Cracked chimney crowns from Marin’s wet winters. Thirty-plus inches of rain a year, with cold snaps mixed in, means water freezes and thaws inside hairline crown cracks. The crack widens, water gets into the masonry, and spalling follows. Most Larkspur crowns need sealing or rebuilding every 10 to 15 years.
- Corroded dampers and caps from bay air. Morning fog and salt air off Richardson Bay eat at metal components. A damper that’s rusted half-open kills your draft and lets heat escape up the flue. This is common on older Larkspur homes and usually means a damper replacement, not a full chimney overhaul.
- Cracked flue tiles hidden behind a working fireplace. On Larkspur’s pre-1980 masonry chimneys, the tiles inside the flue can crack while the fireplace still seems to work fine. A Level 1 visual check won’t catch it. The Level 2 camera inspection will, which is why we recommend it any time you buy a home or haven’t had the flue looked at in years.
- Failed flashing where the chimney meets the roof. Larkspur’s older rooflines and shake roofs put extra stress on chimney flashing. Once the metal lifts or rusts through, water tracks into the house. Homeowners often mistake this for a roof leak, when the chimney is the real source.

FAQs About Chimney Repair in Larkspur
If you see crumbling brick, white staining (efflorescence), a rusted damper, or water in the firebox, that’s repair territory, not cleaning. If the chimney drafts fine and the only issue is soot buildup, a sweep is all you need. In Larkspur specifically, our techs check for water damage even when you call for a cleaning, because the wet winters here cause problems that look like “just dirt” but are actually crown and flashing failure. The surest way to know is a camera inspection, which we include with repair quotes. Call (830) 251-4560 and we’ll give you a straight answer.
Yes, in most Larkspur homes we can resurface a cracked clay tile liner using HeatShield, a system we apply inside the existing flue that restores the liner’s smooth, fire-resistant surface without tearing apart masonry. We used this exact approach on a 1940s chimney in Madrone Canyon that had cracked tiles near the smoke chamber, and the homeowner kept their original brickwork. If the liner is too far gone or has shifted, a DuraFlex stainless liner may be needed instead, but full rebuilds are only necessary when the outside masonry has also failed. Call (830) 251-4560 to find out what your flue actually needs.
A Level 2 inspection includes everything in a Level 1 visual check plus a camera scan of the flue interior, the smoke chamber, and accessible voids. It also covers the attic and crawl space around the chimney. In Larkspur, where older masonry flues often hide cracked tiles behind working fireplaces, a Level 2 is the only way to see second-degree creosote or early liner failure before it becomes a fire or carbon monoxide problem. We recommend it any time you buy a house in Larkspur, transfer property, or after any event like a chimney fire or an earthquake. Call (830) 251-4560 to book a Level 2 with camera documentation.
NFPA 211 says chimneys, fireplaces, and vents should be inspected at least once a year. That’s the minimum for safety, not an upsell. In Larkspur, where a wet winter can crack a crown between seasons, an annual inspection catches water damage while it’s still a sealant job instead of a rebuild. Sweeping frequency depends on use, but the annual inspection is non-negotiable. We’ll give you a written report with photos, so you can see exactly what the camera saw and decide what needs doing now versus later. Call (830) 251-4560 to schedule.
We don’t promise same-day repair, because a proper repair quote requires time on the roof and often a camera inspection. What we do promise is a booked appointment inside a specific window, a written price before any work starts, and a clean jobsite when we leave. Larkspur’s chimney problems are seasonal, so the right move is to call us in late summer or early fall before the rain returns, not to wait for a leak in January and hope someone can drop everything. Call (830) 251-4560 and we’ll get you on the schedule.
