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 Inspection Across Dublin
A Level 2 chimney inspection in Dublin typically runs $250 – $450, and most inspections are completed the same week you call. That price includes a camera scan of the entire flue, a written report with photos, and a straight answer on whether your chimney is safe to burn. Alcott Chimney Sweep has inspected chimneys in western Dublin’s 1960s – 1980s tract homes and eastern Dublin’s post-2000 gas-fireplace subdivisions since 2002. Call (336) 863-3889 and you’ll get a real person, a written price before any work begins, and a technician whose name and photo you’ll see before we arrive.
Why Alcott Chimney Sweep Is Dublin’s Preferred Chimney Inspection Company
Most chimney companies treat all of Dublin the same. We don’t, because the housing stock isn’t the same. A 1972 ranch home off Village Parkway has a masonry chimney with a terra-cotta flue liner that’s never been touched. A 2011 two-story in Jordan Ranch has a prefabricated gas fireplace with a direct-vent pipe. Those are two completely different inspections, and a company that doesn’t know the difference will miss what matters in your home.
Ruben Castellano built Alcott Chimney Sweep around a simple idea: homeowners deserve to know exactly who’s coming through the door and exactly what they’re paying before the work starts. Every technician we send to Dublin is background-checked, identity-verified, uniformed, and announced to you by name and photo before arrival. That’s the Threshold Standard, and it’s not an upgrade. It’s how we’ve operated since 2002.
We also put our guarantees in writing, every time. Every repair carries a written guarantee. If that repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every inspection finding we act on in Dublin.
Level 2 Chimney Inspection in Dublin
A Level 2 Chimney Inspection in Dublin is the inspection you need if you’ve changed appliances, changed fuel type, bought or sold the home, had a chimney fire, or experienced an earthquake, lightning strike, or any structural event. It includes everything in a Level 1 visual check plus a full interior camera scan of the flue, attic access, crawlspace access, and all accessible portions of the chimney structure. In western Dublin’s older homes, this is the inspection that actually finds what’s hiding behind the terra-cotta: spalled liner tiles, cracked mortar joints, and creosote glaze that a brush alone won’t clear.
A Level 2 inspection in Dublin runs $250 – $450 depending on roof access and flue configuration. If we find a problem during the inspection, we show you the camera footage. Not a drawing. Not a scare tactic. The actual video from inside your flue.
When Dublin Homeowners Actually Need This
Most Dublin homeowners don’t need a Level 2 inspection every year. A Level 1 visual check during your annual sweep is enough when nothing has changed. But if you’re buying a home in the Village Parkway corridor, selling one, or you’ve just noticed your fireplace smoking into the house on cold nights, a Level 2 is the right call. It’s also what we recommend after any Spare the Air season where burn nights were consistently skipped and replaced with occasional low-heat fires.
What the Camera Actually Shows
The camera sees what a flashlight can’t: hairline cracks running behind flue tiles, gaps where mortar has failed between tiles, and the exact thickness of creosote glaze at every foot of the flue. We photograph every defect and put those photos in your written report. When we recommend a repair, you’ll see exactly why.
Chimney Leak in Dublin
A Chimney Leak in Dublin is most often caused by failed flashing at the roofline or a cracked chimney crown, not by the bricks themselves. In western Dublin’s 1960s and 1970s tract homes, we routinely find the original galvanized flashing rusted through and the concrete crown spalled from decades of Tri-Valley sun and winter rain. The fix is almost always straightforward: replace the flashing, repair or pour a new crown, and seal the masonry. But the diagnosis has to be accurate, or you’ll pay for masonry work you don’t need.
Chimney leak diagnosis in Dublin runs $150 – $300 when booked as part of a full inspection. We always show you the evidence before we quote a repair, and every repair carries a written guarantee. If it fails, the second visit is free.
Leak vs. Condensation in Dublin’s Climate
Dublin’s winter temperature swings mean chimneys often show condensation damage that looks like a leak. Cold flue walls meet warm gas-appliance exhaust, and the moisture streaks down the inside of the chimney. We test for the difference before recommending any work. A condensation problem usually needs a correctly sized liner, not new flashing.
Shared Stacks in Attached Properties
Some older Dublin attached properties share a masonry stack with the neighboring unit. When one side goes idle for a season, the cross-draft through the shared stack can pull musty air, soot, and even carbon monoxide from the active neighbor’s venting. A Level 2 inspection with a camera can verify whether your flue is properly isolated and whether the shared stack has proper internal separation. This is the kind of issue that gets missed when an inspector does a quick visual check from the roof and calls it done.
Trusted Brands We Service in Dublin
We install and service the same brands chimney professionals specify, and we keep parts for them on our trucks when we work in Dublin: DuraFlex liner systems, HeatShield resurfacing, and Famco caps and dampers. When your inspection turns up a failed terra-cotta liner in a 1978 tract home off Amador Valley Boulevard, we don’t leave and come back later. We quote the HeatShield or DuraFlex fix on the spot, with a written price, and we can typically complete the work the same week. No box-store substitutes, ever.
Common Chimney Inspection Problems We See in Dublin Homes
- Third-degree creosote glaze in western Dublin’s older masonry chimneys. Spare the Air alerts from November through February force skipped burn nights, and the sporadic low-heat fires that do happen leave sticky Stage 2 creosote behind. A single annual sweep often can’t remove what’s built up by March.
- Spalled terra-cotta flue liners in 1960s – 1980s tract homes. The original liners were never meant to last 50 years, and many never got a single camera inspection. Flue tiles crack, mortar joints fail, and the gaps become fire and carbon monoxide pathways.
- Rusted flashing and failed crowns from Tri-Valley weather. Dublin’s hot dry summers bake chimney crowns until they crack, then winter rain gets in. Every year we see flashings that were never properly sealed at installation.
- Shared-stack cross-contamination in attached properties. When a neighbor’s appliance vents into a shared chimney stack, your flue can pull exhaust and carbon monoxide during idle seasons. A camera inspection is the only way to confirm proper internal separation.

FAQs About Chimney Inspection in Dublin
Yes, but what you need is different from what a western Dublin masonry home needs. Post-2000 subdivisions in Jordan Ranch and Positano were built under BAAQMD rules requiring gas-only or direct-vent fireplaces, which means you likely have a prefabricated gas unit with a direct-vent pipe rather than a masonry flue. These still need periodic inspection for vent blockage, debris, bird nests in the termination cap, and gas valve function, but the inspection is a gas-insert inspection, not a traditional masonry sweep. A Level 1 visual check every two to three years is usually sufficient unless you’re buying or selling, in which case a Level 2 is the right call. Call (336) 863-3889 and we’ll tell you exactly what applies to your home’s setup.
Because Spare the Air alerts force you to skip most burn nights, and the occasional fires you do light are short and low-heat. Low-temperature, incomplete combustion produces the sticky Stage 2 creosote that clings to flue walls, rather than the dry Stage 1 ash a consistent hot burn would produce. Add in the long idle stretches where animals and debris find their way in, and you get exactly what we find in western Dublin chimneys every spring: dense, glazed creosote that a single annual sweep doesn’t safely clear. That’s why we recommend a Level 2 camera inspection whenever a western Dublin homeowner reports more than a season or two of sporadic burning.
A Level 1 inspection is a visual check of the accessible portions of your fireplace and chimney, typically done during your annual sweep. It confirms the flue isn’t obviously blocked and the damper works. A Level 2 inspection adds a full camera scan of the flue interior and covers the attic, crawlspace, and all accessible chimney structure. In Dublin’s 1960s – 1980s masonry homes, a Level 2 is the inspection that actually finds spalled liner tiles and hidden mortar joint failures, because those defects are inside the flue where the naked eye can’t reach. If you’re buying, selling, or haven’t had a camera inspection in years, Level 2 is what you need. We’ll give you the written price before the camera ever goes up the flue.
The tell is where the moisture appears and when. A leak from failed flashing or a cracked crown shows up during or right after rain, and it usually stains the ceiling or wall near the fireplace. Condensation happens when warm exhaust meets a cold flue, and it tends to show up as drip marks inside the firebox or streaks on the flue interior, often on cold mornings when the fireplace hasn’t been used in a while. In Dublin’s winter temperature swings, condensation is more common than most homeowners think, and repairing flashing won’t fix it. We test for the difference before quoting any work, and we’ll show you the evidence either way.
Yes, and this is one of the most important inspections we do in Dublin. Attached properties with shared masonry stacks create a real risk: a neighbor’s appliance venting into the same chimney during idle burn seasons can push exhaust and carbon monoxide into your flue. A Level 2 camera inspection verifies that your flue liner is intact and that the internal separation between units is sound. If we find a breach, we’ll show you the camera footage and quote the liner repair or resurfacing with HeatShield or DuraFlex. Every repair carries a written guarantee, and if it fails, the second visit is free. Call (336) 863-3889 to schedule a shared-stack inspection.
