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.

We work across Dublin’s neighborhoods on a regular basis, so we know what this city’s chimneys deal with. The wind along the I-580/680 corridor is not a small detail here. It pushes leaf litter and grit onto roofs and into chimney caps at a rate most other Bay Area cities don’t see. That affects how often caps clog, how fast mortar weathers, and what a repair actually needs to fix. We’ll tell you what’s wrong in plain terms and show you camera footage before you spend a dollar on a fix.
Why Flint Chimney Sweep Is Dublin’s Preferred Chimney Repair Company
Dublin homeowners call us because the crew shows up when we say we will, uniformed and background-checked, and the price on the invoice matches the price on the written estimate. That’s The Garrison Standard, and every Garrison Partners location runs on it. No price moved at the door. No vague “we’ll see what we find” followed by a surprise.
Hank Delano set the tone for how this company operates: document everything, explain everything, guarantee everything. If a repair we make fails within a full year, we come back and fix it at no charge. That’s not a promise we hedge on. It’s in writing on every job we do in Dublin, from cap swaps on Dublin Ranch homes to full crown rebuilds near the high school.
Our dispatchers coordinate from our San Francisco Bay Area office, and our crews serve Dublin locally. That means when you call about a chimney problem off Tassajara Road or near Dougherty Hills, you’re talking to someone who knows the area’s housing stock and the wind patterns that cause so many local draft issues.
Chimney Cap Installation in Dublin
Chimney Cap Installation in Dublin is one of the most common calls we get, and for good reason. The Altamont winds that sweep through the I-580/680 corridor carry leaves, seed pods, and fine grit onto roofs all over town. Without a properly fitted cap with a spark arrestor screen, that debris drops straight down the flue, or worse, collects around the damper and blocks draft. We install caps sized to your flue, using galvanized or stainless steel depending on exposure, and we always confirm the cap clears the top of the flue by at least five inches so draft is not restricted.
When a Dublin Home Needs a New Cap
If you look up at your chimney and see a rusted cap, a missing cap, or a cap that has shifted off-center, water and debris are getting in. Dublin’s winter wind-driven rain makes this worse. A chimney cap is cheap insurance against a far more expensive repair to the flue liner or smoke chamber later.
Cap Installation Pricing
Chimney cap installation in Dublin typically costs $180 – $320 for a standard galvanized cap, including the cap itself and the labor to fit it. Stainless steel caps run higher, usually $320 – $480, and they’re worth it on chimneys with high wind exposure. We tell you the exact price before we start, not after we’re on the roof.
Chimney Cap Replacement in Dublin
Chimney Cap Replacement in Dublin usually means an old cap has rusted through, the spark arrestor screen is packed solid with wind-blown debris, or the cap’s mounting bracket has loosened over years of exposure. We see this a lot on older homes along San Ramon Road and in the Silvergate area, where original caps from the 1980s and 1990s are reaching the end of their useful life. Replacing a cap is straightforward: we remove the old unit, check the flue opening and crown for damage while we’re up there, and fit a new cap sized to the flue tile.
Debris-Packed Caps and Draft Problems
The most common failure we find in Dublin is not a cracked flue tile. It’s a spark arrestor screen so clogged with leaves and grit that the fireplace cannot draft. Smoke rolls back into the room, and the homeowner assumes they need a liner replacement. Often, the fix is a $200 cap replacement and a good sweeping. We’ll always camera the flue before recommending anything more.
When Replacement Is the Call
If your cap is rusted through, missing sections of the screen, or no longer sits square on the flue, replacement is the right call. We also replace caps when we find them undersized for the flue, which is common on Dublin homes where a previous owner or handyman installed a one-size-fits-all cap. A cap that doesn’t fit lets debris in and restricts draft. We stock common sizes from Olympia Chimney and Copperfield, so most replacements are done in one visit.
Trusted Brands We Service in Dublin
We work with professional-grade chimney products from manufacturers that publish their specs. For flue liners and relining jobs, we use DuraFlex stainless steel systems, which stand up to years of heat cycling and the corrosive byproducts of wood combustion. For caps and termination systems, we stock Olympia Chimney and Copperfield products, which are built for high-wind environments like the Dublin hills. We keep common sizes on the truck, which means less waiting for parts and more jobs finished in a single visit. You can verify any brand we name; we’d rather you do.
Common Chimney Repair Problems We See in Dublin Homes
- Debris-packed caps and spark arrestors. The I-580/680 wind corridor funnels leaves and grit onto Dublin roofs. Caps clog fast, draft dies, and smoke rolls back into the fireplace even when the flue is otherwise clean.
- Cracked crowns and spalling mortar. Dublin’s hot, dry summers bake masonry, and winter wind-driven rain forces water into every crack. The freeze-thaw cycle is not extreme here, but the wind-driven rain makes water entry a year-round issue.
- Creosote left too long. First-degree creosote is soft and brushes out easily. Left for years, it becomes third-degree glaze, a tar-like coating that a brush alone cannot safely remove and that greatly increases chimney fire risk.
- Flashing failures around the chimney base. On the low-slope and tile roofs common in Dublin Ranch and the Gale Ranch area, flashing separates over time. Water runs down the chimney chase and into the ceiling, and the homeowner often does not connect the ceiling stain to the chimney.

FAQs About Chimney Repair in Dublin
Every 25 – 40 fires, or once a year during the burning season, whichever comes first. Dublin’s wind-borne debris can clog caps and reduce draft faster than wood smoke alone, so an annual Level 1 inspection and sweep is the right cadence for most homes here. If you burn green wood or use the fireplace as a primary heat source, sweep twice a season. Call (830) 251-4560 and we’ll give you a clear recommendation for your setup.
First-degree creosote is a soft, flaky soot that brushes out easily with standard sweeping. Third-degree creosote is a dense, tar-like glaze that builds up after years of burning and can ignite at a much lower temperature. In Dublin, where many homes have older fireplaces and burning habits that favor long, slow burns, creosote can progress from first to third degree faster than homeowners expect. Camera inspection tells us which one you have, and whether a simple sweep or a chemical treatment and mechanical removal is needed.
Often, yes, and we’ll tell you when that’s the case. Minor mortar cracks and surface crown wear can wait until the next scheduled maintenance, as long as no water is getting into the flue. We take camera footage and show you exactly what we found, so you can decide with evidence rather than a sales pitch. But a cracked liner, heavy creosote glaze, or a chimney actively leaking water into the house should be addressed promptly, because those problems get more expensive the longer they sit. We’ll never push a repair we can’t show you on camera.
Yes, on every chimney repair visit. We run a camera down the flue and through the smoke chamber, and we photograph the cap, crown, flashing, and any damage we find. You get that photo report before any repair is quoted, so you can see the problem with your own eyes. This is standard practice for our crews in Dublin, not an add-on charge.
We install DuraFlex stainless steel liners for relining work, and we stock Olympia Chimney and Copperfield caps and termination systems. These brands publish their specs publicly, and we’re happy to point you to them. We choose materials by the job’s demands, not by what is cheapest or what we have too much of on the shelf.
