Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Claremont
A chimney sweep in Claremont typically costs $189 – $279 for a standard fireplace cleaning, and most jobs take 60 – 90 minutes from setup to final walkthrough. If you live in the Village, near the Claremont Colleges, or up toward the foothills off Padua Avenue, our technicians know your chimney’s age and construction before they even ring the bell. That matters, because a 1924 Craftsman flue and a 1975 prefab chase need different hands and different judgment.
Mantel Chimney Sweep serves Claremont with full-service chimney work, from basic Chimney Sweep work to liner restoration and crown rebuilds. As the peak burning months approach, early booking avoids the wait-list. Call Roland Vega’s team at (844) 821-5749 and we’ll schedule a sweep, inspection, or camera evaluation for your fireplace, stove, or dryer vent.
Why Mantel Chimney Sweep Is Claremont’s Preferred Chimney Sweep Company
We’ve spent enough days on Claremont rooflines to recognize the failure patterns that other companies miss entirely. The pre-war bungalows along Indian Hill Boulevard and around Memorial Park share a construction DNA: gorgeous stacked-stone or brick masonry, clay tile liners that have quietly reached end-of-life, and original crowns that were never weatherproofed to modern standards. When a homeowner in Claremont calls a sweep-only operator, the industry pattern is predictable: brush the flue, write a report, and leave. We repair what others can only report.
That’s the difference with Mantel. Roland Vega built this company around the chimney and hearth ecosystem, not as a side service bolted onto general handyman work. When we find cracked clay tiles or spalling mortar during a Claremont job, we can perform the relining or restoration right then – using HeatShield cerfractory sealant or a DuraFlex flexible stainless liner – instead of handing you a referral and a worried headline. Our Claremont customers don’t get upsold; they get camera footage they can see with their own eyes.
We stock the materials Claremont’s older housing stock actually needs, from proper crown sealants to liner components, so turnaround on repairs doesn’t stretch for weeks while someone waits on a supply order.
Styles & brands we work with





Gas Fireplace Cleaning in Claremont
Gas Fireplace Cleaning in Claremont runs $149 – $219 for a full service that includes glass removal, log inspection, burner cleaning, and vent-path verification. Many homeowners assume a gas fireplace never needs attention because there’s no wood or ash, but that assumption is exactly how soot builds up on thermocouples, glass fogs permanently, and burner ports clog. In Claremont, where homes often run their gas logs for ambience rather than heat, dust and pet hair get pulled into the air intake and baked onto internal components.
What a full gas service actually includes
We remove the glass assembly and logs, vacuum the firebox, clean the burner and pilot assembly, and test the thermopile voltage. We also check for gas leaks at every fitting using a calibrated detector. The final step is a draft verification so we know the vent still pulls correctly.
When Claremont homeowners notice it’s time
Soot streaking on glass, a lazy yellow flame instead of a clean blue one, or a smell that lingers after the unit shuts off. Any of those signals means the burner needs attention before a restriction turns into a venting problem. Ignoring it invites carbon monoxide risk, which no one should gamble with.
Chimney Maintenance in Claremont
Chimney Maintenance in Claremont is not a once-a-decade luxury; it’s an annual discipline for anyone with a working wood fireplace, and $229 – $319 covers a maintenance visit that includes sweeping, a Level 1 inspection, crown assessment, and minor pointing touch-up where accessible. Claremont’s dry summers pull moisture from masonry, and when the first rains arrive after a long hot season, any small crown crack or mortar gap turns into an active leak path. That leak is what starts spalling and smoke chamber damage.
Crown maintenance and water entry
The cracked ‘Claremont-style’ crown is our most common finding on pre-WWII stacked-stone chimneys. Older crowns were often built with plain concrete mix and no expansion joint, so temperature swings crack them within a season or two. We repair crowns using proper repair mortar and apply a breathable crown sealer, so water stops getting behind the brick.
Seasonal readiness for the burn season
Many Claremont fireplaces sit idle from March through November. That’s long enough for creosote from the last season’s final fires to cure into a hard, glassy glaze, and for sycamore leaves or oak debris to pack the flue cap area. The best time to schedule maintenance is late September through early November, before the first serious cold snap lands.
Trusted Brands We Service in Claremont
We don’t install generic parts on quality chimneys. Mantel works with a curated set of professional chimney-industry brands, including HeatShield, Gelco, and Olympia Chimney. HeatShield is our primary material for flue liner restoration on Claremont’s original clay tile flues, because it’s a cerfractory sealant formulated specifically for this application, not a hardware-store patch. When a full liner replacement is the right call, we install DuraFlex flexible stainless systems. On the repair side, Gelco repair in Claremont and Olympia Chimney supply the crowns, caps, and flashing components we use for pre-war masonry restoration. Because we keep these materials in our own inventory, a Claremont homeowner doesn’t wait for a distributor to ship anything.

AfterCommon Chimney Sweep Problems We See in Claremont Homes
- Cracked original crowns on 1920s chimneys. The stacked-stone and brick chimneys in the Village and college-adjacent blocks were built with crowns that crack after the first big post-summer rain. Once water enters, smoke chamber damage follows within two or three seasons.
- Clay tile liners at end-of-life. Many original clay tile flues in Claremont’s pre-WWII housing stock are 80 to 100 years old. When tiles spall or mortar joints fail, hot gases can reach combustible framing, which is a chimney fire waiting for the right conditions.
- Third-degree creosote glaze. The combination of oak and sycamore fires with low-heat burns creates hard creosote deposits that brushing alone won’t remove. This needs chemical treatment or, if the flue is compromised, a reline.
- Venting into unlined stacks. Some older Claremont homes had gas appliances vented into masonry chimneys never designed for modern furnace or water heater exhaust. Those acidic gasses eat through mortar and masonry from the inside out, often unnoticed until a Level 2 inspection finds it.
Pricing for Chimney Sweep in Claremont, CA
A standard chimney sweep in Claremont runs $189 – $279 for an open fireplace, with gas fireplace cleaning landing between $149 – $219. A full maintenance visit, which includes the sweep, Level 1 inspection, crown check, and touch-up pointing where reachable, typically runs $229 – $319. When a camera inspection is needed (a Level 2), expect to add $125 – $175 for the footage and written report.
The honest variable is condition. A clean, well-maintained flue sweeps in under an hour and stays at the low end. A flue with years of cured creosote, animal nesting, or deteriorating mortar takes more time and moves toward the top of the range. We never quote a number without seeing the flue first, and we never recommend a reline without camera evidence you can watch yourself. Call (844) 821-5749 for a free estimate; we’ll give you the range up front and the exact number after we look at what we’re working with.

FAQs About Chimney Sweep in Claremont
You need a camera inspection before anyone can answer that. A 1920s clay-tile flue can be perfectly serviceable, or it can be spalling and unsafe, and the difference is not visible from a brush. Our technician runs a camera up the flue, shows you the footage on-screen, and only then recommends a HeatShield relining if the joints are cracked or the tiles are flaking. A standard sweep runs $189 – $279; a camera inspection adds $125 – $175. If the flue is sound, you save the cost of an unnecessary reline. If it isn’t, you see exactly why. Call (844) 821-5749 to schedule the inspection.
Because original crowns on Claremont’s 1920s and 1930s masonry chimneys were built with basic cement and no expansion joint, and the city’s hot, dry summers bake that material until it micro-cracks. The first big rain after summer finds every weak point and opens it. We rebuild crowns with proper crown mix and apply a breathable sealer, which stops water from running down behind the brick and into the smoke chamber.
Third-degree creosote looks like a black, shiny glaze coating the flue walls – it’s not the flaky stuff that a brush removes. It forms when oak and sycamore fires burn low and cool, and it can’t be swept out with a standard brush. If you see a hard, glossy coating or have had a slow-burning fire habit, we’ll confirm it with a camera and discuss chemical treatment or relining. We saw this exact situation on a 1923 Craftsman near the Claremont Colleges, where a homeowner who had never swept the fireplace had third-degree creosote glazing the clay tiles. After showing the footage, we recommended a HeatShield relining and rebuilt the cracked crown before the first winter rain.
Yes. Gas fireplaces produce soot, dust intrusion, and condensation that corrode burner components and can clog vent paths over time. A gas fireplace cleaning in Claremont runs $149 – $219 and includes glass removal, burner cleaning, pilot and thermopile checks, and a draft verification. Even if you never burn wood, your gas logs should be cleaned annually for both performance and carbon monoxide safety.
A Level 1 inspection is a visual check of the accessible flue, firebox, damper, cap, and crown, and it’s bundled with every standard sweep. A Level 2 adds a full video camera scan of the flue interior, from firebox to cap, documenting any cracks, spalling, or blockages inside the liner. For any Claremont home with a pre-war clay-tile flue or a chimney used after years of inactivity, we recommend Level 2 because that’s the only way to see what’s actually happening inside the flue. Estimates are free; call (844) 821-5749 and we’ll tell you which level your home needs.
