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.

Call (336) 863-3889 to schedule, and you’ll know exactly who’s coming before we arrive.
Claremont homes have a particular problem that most LA Basin cities don’t. We’ll explain it below, but the short version is this: older attached homes share flues, Santa Ana winds fill them with debris, and the fire hazard zone designation means your insurance company may want a written report. We write that report.
Why Alcott Chimney Sweep Is Claremont’s Preferred Chimney Inspection Company
Ruben Castellano founded Alcott Chimney Sweep in 2002, and the company has been part of the Threshold Group family of home-service companies since day one. What that means for a Claremont homeowner is practical: every technician who steps onto your property has already passed a background check and identity verification under what we call the Threshold Standard. You receive the technician’s name and photo before the truck leaves the office. When they ring your bell, they show a photo ID badge. No exceptions, no substitutes.
We hear from Claremont customers that the ID badge and name-before-arrival policy is the reason they booked us over a cheaper flyer that got left on the porch. That’s especially true for parents with young kids at home during the day and older homeowners who’ve lived in the Village for decades. A chimney inspection means someone in your house and on your roof. You should know who that person is before the door opens.
Every inspection we do in Claremont ends with a written price for any recommended work, before any of it starts. And every repair we make carries a written guarantee. If the repair fails during the coverage period, the second visit is free. That’s our 365-Day Done Right Promise, and it’s written onto every job sheet.
Chimney Inspection Services in Claremont
Chimney Inspection Services in Claremont cover three nationally recognized levels: Level 1, Level 2, and Level 3. A Level 1 is a visual check of the accessible parts of the firebox, damper, and flue interior, and it’s what we recommend for a chimney that’s been used regularly and hasn’t changed since its last inspection. In Claremont, a Level 1 inspection runs $189 – $249.
A Level 2 inspection adds a camera scan of the full flue interior and includes the attic, crawlspace, and exterior crown and flashing. That’s the inspection most Claremont real estate transactions require, and it’s the one insurance carriers in the Very High Fire Hazard Severity Zone above Baseline Road are increasingly asking for. A Level 2 in Claremont runs $329 – $429. Level 3 inspections involve opening a portion of the chimney or flue to inspect concealed areas and are only ordered when a Level 2 finds a hazard that needs a closer look. Level 3 work is quoted individually after the Level 2 findings are in.
Camera Inspection
We run a video camera through the full flue during every Level 2 inspection. You see the footage, not just a “passed” or “failed” on a paper slip. In Claremont’s older brick chimneys, the camera often shows what a visual check misses: creosote glaze below the throat, cracked flue tiles, or a missing liner section hidden behind an old damper.

Real Estate Inspection
Claremont’s 1910s through 1940s housing stock moves hands often, and a real estate chimney inspection here has specific stakes. The Village district’s Craftsman and Period Revival homes frequently have unrelined brick flues that were built before modern liner standards existed. We write our real estate reports in plain language, with photos, so a buyer and seller can read the same page.

Chimney Flue Inspection in Claremont
Chimney Flue Inspection in Claremont means specifically examining the interior passage that carries smoke from your firebox to the outside, not just looking at the fireplace itself. In this city that distinction matters more than in most places. Claremont’s northern foothill elevation sits around 1,170 feet at the base of the San Gabriel Mountains, cold enough in winter that residents genuinely burn wood fires on a regular basis, unlike most of the LA Basin. That consistent use builds creosote – the tar-like residue that causes chimney fires – faster than lower-elevation neighbors like Pomona or Ontario. A Claremont flue inspection runs $189 – $429 depending on the level.
Shared and Adjacent Flue Inspections
In the Village district’s attached Craftsman blocks, many chimneys share a single brick stack between two homes, or run wall-adjacent with separate flues inside the same mass. An inspection that only looks at one firebox misses the cross-contamination risk from the neighbor’s side. We check the full stack. Our Chimney Inspection team has found a neighbor’s water heater venting into a homeowner’s flue because the dividing masonry had crumbled inside an unlined brick stack.
Insurance-Required Flue Inspections
Above Baseline Road, where Claremont’s parcels fall inside California’s High or Very High Fire Hazard Severity Zones, insurers increasingly ask for a documented flue inspection before renewing or writing a policy. We provide the written report with photo evidence, and we write it in the format insurance underwriters actually read. No vague “appears serviceable” lines. Specific findings, specific recommendations, dated and signed.
Trusted Brands We Service in Claremont
We service and install professional trade chimney systems throughout Claremont, and we stock parts for DuraFlex liner systems, Olympia Chimney components, and HeatShield resurfacing materials. That matters when a Village chimney needs a liner replaced and a repair can’t wait through a parts order. We keep the same brands chimney professionals specify, not box-store substitutions. For Claremont homeowners with older Famco or Copperfield components, we can evaluate compatibility and source replacement parts directly.
Common Chimney Inspection Problems We See in Claremont Homes
- Shared-stack cross-contamination. In the Village’s attached Craftsman and Period Revival homes, a neighbor’s water heater or furnace can vent into your flue through deteriorated internal masonry. A single-firebox inspection never catches this. We inspect the full stack from both accessible sides whenever the structure allows.
- Santa Ana wind debris backfilling. The Santa Ana winds that funnel through the Pomona Valley corridor hit Claremont’s foothill elevation with real force. Between burn seasons, those winds drive ash, leaves, and roof debris into unlined brick flues. A flue that read as clear in spring can hold third-degree creosote glaze below the visible throat by fall.
- Crown cracking and spalling from freeze-thaw cycles. Claremont’s mountain-facing cold nights create freeze-thaw stress on original brick crowns from the 1910s through 1940s. Spalling brick and cracked crowns let water in, which accelerates liner breakdown and mortar failure. Under red-flag fire conditions, a compromised crown is an ignition path, not a cosmetic issue.
- Missing or failed stainless liners in unrelined historic chimneys. Many Claremont homes built before the 1950s still run original unlined brick masonry with no stainless liner. Those chimneys were never designed for modern appliance venting. We find these routinely, and we document them for insurers who increasingly won’t cover them without a resurfacing or liner install.
Pricing for Chimney Inspection in Claremont, CA
A Level 1 chimney inspection in Claremont runs $189 – $249. A Level 2 inspection with camera scan, attic and crawlspace access, and full exterior evaluation runs $329 – $429. If a Level 2 reveals a hidden problem that requires a Level 3, we quote that separately after you’ve seen the camera footage and understand exactly why the additional step is needed. No one at Alcott will recommend a liner replacement or masonry rebuild without showing you the photographic evidence first. If the work can safely wait, we say so.

FAQs About Chimney Inspection in Claremont
Yes, and in Claremont the reason is often the Santa Ana winds, not your own burning habits. The Pomona Valley corridor’s wind events backfill unlined brick flues with ash, leaves, and roof debris between seasons, so a flue that sat unused can be partially blocked without you ever lighting a fire. An inspection clears that out and documents the condition before your first burn of the season. Call (336) 863-3889 to schedule, and we’ll tell you exactly what we see.
Because in the Village district’s attached Craftsman and Period Revival blocks, many homes share a single brick chimney stack or run wall-adjacent flues inside the same masonry mass. When the internal dividing brick crumbles, your neighbor’s water heater or furnace can vent into your flue and into your living space. That’s cross-contamination. Our Level 2 camera inspection examines the full stack, not just your firebox, because in Claremont that’s the only inspection that catches this. If we find it, we document it for your insurance carrier. Call us for an exact quote; estimates are free.
We write our Claremont reports to the specific documentation standard that insurers in California’s High and Very High Fire Hazard Severity Zones expect – photo evidence, dated findings, specific recommendations, signed by the technician. The northern foothill parcels above Baseline Road fall inside those zones, and we’ve had underwriting departments accept our reports for policy renewal. We can’t promise what your specific carrier will accept, but we write the report with enough specificity that most do. Call (336) 863-3889 and mention your insurance requirements when you book.
First-degree creosote is a light, flaky soot that brushes off easily. Third-degree creosote – what we call glaze – is a hard, tar-like coating that’s baked onto the flue interior and won’t come off with a standard brush. It’s also the form that burns hottest and is the primary fuel for chimney fires. Claremont’s elevation keeps burn seasons long enough that glaze accumulates faster than in flatland cities nearby, and it often sits below the visible throat where a basic visual check won’t find it. Our camera inspection finds it and our cleaning removes it. For a free estimate, call us.
We use roof ladders with padding, gutter guards, and edge-protection gear designed for tight eaves-to-eave gaps and steep original pitches. The Village’s narrow streets and closely spaced Craftsman homes require a different approach than a wide suburban roof in Upland. Our technicians carry the equipment to access those tight spaces safely, and the Level 2 inspection includes the crown and flashing check that’s hard to do from the ground. If you’re on a tight Village block, tell us when you book and we’ll send a tech outfitted for it. Call (336) 863-3889 and we’ll schedule your free estimate.
