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.

San Marino’s chimneys aren’t like the rest of the metro. Most were built between 1920 and 1940 for wood or coal, and many still have no clay flue liner at all. That changes what a repair actually involves here, which is why we approach every San Marino job with a Chimney Inspection in San Marino before we recommend anything.
Why Flint Chimney Sweep Is San Marino’s Preferred Chimney Repair Company
Homeowners off Huntington Drive, St. Albans Road, and Lorain Road call us because we do something most chimney companies won’t: we put the price in writing before we start. No moving numbers at the door. No surprise line items after the fact. Every repair from Flint Chimney Sweep carries the 365-Day Done Right Promise, a written guarantee valid for a full year from the service date. If a covered repair fails in that window, we come back and make it right at no charge.
We’ve been doing this since 2002 as part of the Garrison Partners family of independently owned chimney service companies.

And when you call (830) 251-4560, a live person answers, 24 hours a day, 7 days a week. No voicemail trees.
Our Chimney Repair team works under The Garrison Standard, the same documented code every Garrison Partners location follows. Price, scope, and guarantee go in writing before a single tool comes off the truck. That’s the way it should work.
Chimney Cap Installation in San Marino
Chimney cap installation in San Marino is often the single most protective repair we do, especially on the uncovered masonry flues common in this city’s 1920s and 1930s homes. A properly sized stainless or copper cap keeps rain, leaves, and birds out of the flue, and it stops the wind-driven downdrafts that push smoke back into older fireplaces on gusty days near the San Gabriel foothills. Most cap installations in San Marino run $350 – $700 depending on the cap material and flue dimensions.
When an older San Marino chimney needs a cap
If your chimney was built before the 1950s and the flue opening is still uncovered, every rain event is putting water directly onto bare brick or an old clay liner. In San Marino’s Mediterranean climate with its dry summers and concentrated winter rains, that cycle of wetting and drying accelerates spalling and mortar failure. A cap won’t fix damage that’s already there, but it stops the problem from compounding while we address the rest.
What a proper cap installation includes
We measure the flue tile, spec a cap from Olympia Chimney or Famco that sits tight without restricting draft, and secure it with mechanical fasteners, not just pressure fit. We also inspect the crown at the same time. If the crown is cracked, a cap alone won’t solve water intrusion, and we’ll tell you that plainly before you spend the money.
Chimney Cap Replacement in San Marino
Chimney cap replacement in San Marino is common on homes where the original cap has rusted through or blown off entirely, which we see regularly on exposed chimneys near Stoneman School and the older neighborhoods around Mission Street. A rotted cap is worse than no cap in some cases, because the rusted edges and failed mesh can partially obstruct the flue and affect draft. Replacement costs in San Marino typically run $300 – $650, including removal of the old cap and installation of the new one.
Rusted caps and what they do to the flue
A cap that has rusted through is letting water in while fooling the homeowner into thinking the chimney is protected. We inspect the cap every time we’re on a San Marino roof for a sweep or repair, and we photograph exactly what’s there. If the mesh is gone, you’ve also got open access for birds and squirrels, which we pull nests out of more often than most people would guess.
The difference between cap replacement and repair
Sometimes a cap is structurally sound but the screen or the corner joints need work. If it’s a minor fix, we say so and price accordingly. We do not push a full replacement when a repair gets you another few years. But when the metal is compromised, replacing it with a stainless cap from Gelco or Famco is the right call, and it’s usually a 30-minute job once we’re on the roof.
Trusted Brands We Service in San Marino
We install and work with professional-grade chimney materials that you can verify independently: HeatShield resurfacing systems for flues with cracked clay liners, Olympia Chimney caps and dampers, and Famco stainless caps and accessories. We stock common cap sizes and damper parts for San Marino’s older clay-tile flues, which means shorter turnaround for most cap installations and replacements. When a repair calls for a component we don’t have on the truck, our Los Angeles dispatch coordinates delivery to San Marino inside a few business days. You’re not waiting on a distributor to ship from the East Coast.
Common Chimney Repair Problems We See in San Marino Homes
- Unlined masonry flues from the 1920s – 1940s: San Marino’s Spanish Colonial and Craftsman homes were frequently built without any clay flue liner at all. Bare brick spalls over decades of heat cycling, and the rough surface collects first-degree creosote faster than a smooth liner would, which is exactly what a Level 2 camera inspection reveals.
- Cracked crowns and earthquake-damaged mortar joints: Years of Southern California ground movement and expansion-contraction cycles from our hot, dry summers have opened mortar joints and chimney crowns across San Marino. Water gets in, rusts the damper shut, and seeps into the smoke chamber where you won’t see it until the damage is well advanced.
- Rusted or missing chimney caps: Original caps on 80- and 90-year-old chimneys have long since failed. Rain goes straight down the flue, sitting against the brick and accelerating every other problem on this list.
- Flashing that separates from rooflines: San Marino’s older tile and shake roofs settle over time, and the chimney flashing that was once watertight pulls away. We often repair flashing and cap work in the same visit, because the roof penetration and the chimney top are both points where water gets in.

FAQs About Chimney Repair in San Marino
For a San Marino home built before 1940, a Level 2 camera inspection is worth doing every 2 – 3 years, or before you buy the house and before you burn the first fire of the season. The reason is simple: most of these chimneys were never lined, and bare brick conditions change faster than a swept-out clay liner would. A Level 1 visual sweep is what most companies do; we’re talking about a camera inspection where we see the entire flue surface, smoke chamber, and firebox on video. Call (830) 251-4560 and we’ll be straight with you about whether your chimney needs it this year or can wait.
Everything a flashlight cannot. The camera goes up the flue and down from the top, showing bare brick, gaps in mortar, broken flue tiles, creosote stage and thickness, the condition of the smoke chamber, and whether the damper is working. On a 1928 Spanish Colonial off Lorain Road near the Huntington Library, our tech pulled a Level 2 camera and found the flue had never been lined, with spalling brick and first-degree creosote flaking off the walls. That’s the kind of evidence you don’t guess at, and it’s why we include the photo report with every inspection. The report is yours to keep.
Correct. Third-degree creosote is a hardened glaze that has baked onto the flue walls and does not come off with a wire brush. In San Marino, where unlined flues are common and draw patterns can be uneven, creosote can progress from fluffy first-degree to tarred glaze faster than homeowners expect. When we see it, we tell you and recommend a resurfacing system like HeatShield rather than trying to scrape the flue walls, which can damage older brick. Get a camera look before you accept a brush sweep as the whole job.
Some repairs can, and we’ll say exactly that when it’s true. Cracked but stable mortar, a crown with hairline cracking that hasn’t opened to the flue, or a cap that’s functional but aging can often wait until spring, when scheduling is easier. What should not wait: water actively entering the firebox, visible spalling on the flue, or a rusted-open damper that’s pulling cold air down the chimney all winter. The fastest way to know is a camera inspection with a written report, then a straight answer from us. Call (830) 251-4560 for an exact quote, estimates are free.
We do. Since cap, flashing, and flue all sit at a common intersection with the weather, addressing them in one visit saves you labor and roof time. In San Marino specifically, older homes often have all three problems at once: a failed cap, separated flashing, and a lining that is missing or peeled. We’ll show you the photo report, price the whole scope in writing, and you decide which line items to approve. Nothing goes on the invoice that wasn’t agreed to in advance.
