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 Crestline
A chimney sweep in Crestline typically runs $189 – $289 for a standard fireplace with a masonry flue, and most jobs are done in 60 – 90 minutes. That price covers a full top-down sweep, creosote and soot removal, the firebox, smoke shelf, damper, and cap, plus a camera check if we find anything worth showing you. Call (833) 467-7685 and we’ll get you on the schedule before the first serious freeze.
We work the whole 92325 ZIP, from Lake Gregory up through the Old Town stretch and out toward the Rim of the World Highway. Crestline chimneys see conditions that flatland sweeps never deal with: a heating season that starts in October and doesn’t end until April, pine needles dropping into caps from a dense canopy, and freeze-thaw cycles that work on crowns and mortar joints all winter. You don’t need a company that visits Crestline once a month. You need someone who knows what this elevation does to a flue.
Why Ontario Chimney Is Crestline’s Preferred Chimney Sweep Company
Al Vickers runs Ontario Chimney, and he’s spent years working mountain chimneys in the San Bernardino range. That matters here because a Crestline chimney is not the same animal as a Rancho Cucamonga chimney. Elevation changes draft. Snow load changes caps and crowns. A long burn season of pine, cedar, and oak changes the creosote you’re dealing with; it glazes instead of brushing loose. We’ve built our reputation in 92325 on showing homeowners the inside of their flue before we ask them to spend a dollar on repair.
Homeowners in Crestline keep calling us because we carry the odd-sized caps and dampers these older cabins need. You won’t find a 7.5-inch clay-tile cap at the hardware store down the hill, and you shouldn’t have to wait two weeks for a special order. We stock the common Crestline diameters on the truck. That’s the difference between a sweep that takes one visit and a sweep that turns into a saga. Our Chimney Sweep team also handles the full repair scope, so you’re not coordinating a cleaner and a contractor separately when the camera shows something that needs attention.

Fireplace Cleaning in Crestline
Fireplace Cleaning in Crestline means more than brushing loose ash out of the firebox. It’s removing the glazed creosote that’s bonded to your flue walls, cleaning the smoke shelf and damper assembly, and making sure the firebox and its clearances are still in workable shape. In 92325, we see fireplaces that get used as primary heat from October through April, so the creosote isn’t fluffy; it’s shiny and tar-like. A simple brush job won’t touch it. We use rotary heads and hand scrapers to break the glaze, then run a camera if the buildup suggests deeper problems.
You’ll know you need fireplace cleaning in Crestline when the fire seems lazy, smoke backs into the room, or you smell a sharp, acrid odor near the hearth even when it’s cold. That’s creosote off-gassing, and it’s a fire waiting for the right conditions. If you’ve just bought a cabin near Lake Gregory or off the Old Town stretch and you don’t know when it was last swept, schedule a cleaning before your first burn. A standard fireplace cleaning in Crestline runs $189 – $289 depending on flue height and access.
Creosote Removal Specifics
Third-degree glazed creosote is common in Crestline cabins because pine and cedar burn hot but produce heavy resin buildup, and the long burn season means it keeps layering. We remove it with rotary whip heads and chemical treatments when needed, never just a wire brush. If we can’t fully remove the glaze, we’ll tell you plainly and show you the footage.
Soot and Ash Clearing
Soot removal sounds minor, but in these older fireboxes it often hides blocked smoke shelves and animal nests. We clear the firebox, smoke shelf, and damper housing, and we check the cap for the pine needles and cedar debris that snow and wind push into 92325 flues all winter.
Chimney Services in Crestline
Chimney Services in Crestline cover the whole stack, not just the flue. We inspect the crown, the mortar joints, the flashing at the roofline, the cap and spark arrestor, and the damper assembly. In Crestline specifically, freeze-thaw cycles crack chimney crowns and spall mortar joints faster than most homeowners expect, and those openings let snowmelt into the masonry. That water freezes, expands, and widens the crack. A few winters of this and you’ve got a chimney that needs real repair, not a fresh tube of caulk.
Our team handles sweep-to-repair in one visit when the job is straightforward. If the camera shows a cracked clay-tile joint or a failed crown, we’ll show you the footage before we quote anything. You’ll know whether it needs work now or can wait until spring. A Level 1 inspection plus sweep in Crestline runs $189 – $289. A Level 2 inspection, which includes camera work through the full flue, runs $249 – $399 depending on access and roof pitch.
Cap, Crown, and Damper Checks
Crestline’s older cabins often have original caps and dampers that were undersized even when they were installed. We check for rusted spark arrestors, cracked crown mortar, and dampers that no longer seat. If yours needs replacing, we carry the common Crestline diameters, including the odd sizes these 1960s and 70s builds used.

Camera-Verified Findings
Nothing we recommend comes without footage you can see. Whether it’s a cracked clay tile, a glazed smoke chamber, or a spalled mortar joint, we run the camera and review it with you. This is where the industry’s worst upselling happens, and we’d rather show you a healthy flue and send you home than sell a reline you don’t need.

Trusted Brands We Service in Crestline
We install and service DuraFlex stainless steel liner systems, the flexible liner of choice for the offset flues and odd geometries common in older Crestline cabins. For ceramic resurfacing instead of a full reline, we use HeatShield, a proprietary system that restores deteriorated clay-tile flues to code compliance without tear-out. And when we replace caps or dampers, we’re pulling from Gelco and Copperfield components, not whatever’s left in a blister pack at the hardware store. That’s not elitism; it’s what’s required to keep a mountain chimney working through a hard winter. We carry the Crestline-specific sizes on the truck because waiting on a special order during snow season isn’t realistic.

AfterCommon Chimney Sweep Problems We See in Crestline Homes
- Glazed creosote from long pine-fueled burns. The October-to-April heating season builds third-degree creosote fast, and a standard wire brush won’t remove it. We use rotary heads and camera verification to get it out and show you the result.
- Storm-clogged caps and spark arrestors. Pine needles, cedar debris, and snow load either block the cap or push debris down into the flue. What looks like a routine sweep is often a clear-out and draft correction.
- Freeze-thaw crown and mortar damage. Snowmelt seeps into cracks, freezes, and spalls mortar joints and crown edges. Left alone, water gets into the firebox and the framing around the chase.
- Clay-tile flue deterioration in 1960s – 80s cabins. Hairline cracks at the tile joints let heat and creosote into areas they shouldn’t reach. We check with a camera and recommend HeatShield resurfacing or a DuraFlex liner only if the footage justifies it.
On a 1960s cabin off the Old Town Crestline stretch, we pulled a squirrel’s worth of pine needles and a cracked spark arrestor out of a masonry stack, then ran a camera up the clay-tile flue and found third-degree creosote glazed across the smoke chamber and a spalled mortar joint three courses up. We showed the homeowner the screen footage before quoting anything, removed the glaze with a rotary head, and reset the crown and cap with a truck-stock replacement sized to the original dimensions. That’s the job. Not a scare quote. Actual work, with evidence.
Pricing for Chimney Sweep in Crestline, CA
A standard chimney sweep in Crestline runs $189 – $289 for a masonry fireplace with one flue. A Level 1 inspection is included with that sweep. If you want a Level 2 camera inspection, plan on $249 – $399 depending on roof pitch and access, and that’s the one we recommend for any cabin that hasn’t been inspected in years or that’s just changed hands. Prefab metal chimneys run toward the lower end. Odd roof pitches, snow-guarded access, and heavily glazed flues push the price up.

FAQs About Chimney Sweep in Crestline
You can’t tell from the outside, and anyone who tells you otherwise is guessing. Third-degree glazed creosote looks like shiny black tar bonded to the flue wall, and it requires rotary removal, not a brush. We run a camera after the initial sweep, and if glaze remains, we show you the footage on the spot. Call (833) 467-7685 for a Level 2 inspection with camera verification.
Not necessarily. Clay-tile flues in good condition with intact joints don’t need a liner. If the camera shows cracked or spalled tiles at the joints, you’ve got two options: a HeatShield resurfacing that restores the existing flue, or a DuraFlex stainless liner. Either recommendation comes with footage, not just a verbal claim. Don’t accept a liner quote without camera evidence.
Because the cabins built in the 1950s through 70s used odd-sized caps and dampers that don’t match modern off-the-shelf dimensions. The hardware store down the hill doesn’t stock them, and big-box retailers never will. We carry the common Crestline diameters on the truck, so a cap or damper replacement doesn’t turn into a two-week wait during snow season.
Yes, and for Crestline specifically it’s about what the winter did to the chimney, not how often you used it. Snow load, freeze-thaw cycles, and spring pine-needle drop all work on your cap, crown, and flue even if you never lit a fire. An annual inspection catches water damage before it becomes a masonry repair. If you burned even a cord of pine, the creosote is already building regardless of how few fires that took.
Elevation and fuel. At 4,500 – 5,000 feet, thinner air changes your draft, and pine and cedar burn with heavy resin content that produces dense creosote. The long heating season means it layers without a break, and the result is the glazed buildup we’ve been describing; it won’t brush out, and it’s a real fire risk. Draft problems are usually a combination of glazed flue walls, a clogged cap, and a flue that was undersized for the firebox from day one. Call (833) 467-7685 and we’ll identify which of those you’re dealing with.
