Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in Crestline, CA
We provide independent Gelco chimney cleaning and repair across Crestline, and the thing that sets our work here apart is simple: we know how these units fail at 5,000 feet. Most Crestline calls we take aren’t routine sweeps. They’re glazed creosote from a full winter of pine burning, or a rusted cap that’s been letting snowmelt and needles into the flue since March. If you own a Gelco in the 92325 ZIP, call (833) 467-7685 and we’ll tell you straight what it needs.
Ontario Chimney has serviced Gelco fireplaces and inserts across the San Bernardino Mountains for years, including San Bernardino Gelco service. We’re an independent service provider, not a manufacturer affiliate, which means our loyalty is to the homeowner and the condition of the flue, not a brand quota. Our techs stock the odd-sized caps, dampers, and gaskets that Crestline hardware stores never carry. That matters up here.
Al Vickers started Ontario Chimney after learning building systems and combustion at Chaffey College and spending the better part of three decades watching what Inland Empire weather does to a chimney. He’ll be the first to tell you that a Gelco in Crestline has a harder life than the same unit down the hill in Rancho Cucamonga. Snow, freeze-thaw, pine needles, a seven-month burn season. We know the brand, and we know this mountain. If you need Gelco sales & service help, we’re your independent crew.
Why Crestline Residents Choose Us for Gelco Service
The short version: we carry parts nobody else stocks up here, and we’ve seen enough Gelco failures in Crestline cabins to know exactly where to look. The long version gets into model lines, freeze-thaw cycles, and why a cracked firebox panel in a 1960s Lake Gregory cabin is a different job than Gelco in Highland or a flatland tract home.
Our approach is simple. We use OEM Gelco parts when they’re available, and quality aftermarket equivalents that meet or exceed the original spec when OEM isn’t realistic for an older unit. We never put a bargain-bin part into a chimney that handles combustion gases. And we’ll tell you when something can wait. A clean flue isn’t a luxury – it’s just how the thing is supposed to work. Plenty of Crestline homeowners have avoided spending money they didn’t need to because we said so.
Being local to the Crestline service area means we understand what this elevation does to metal and masonry. We don’t quote work we haven’t seen. We show you the evidence, walk you through options, and let you decide.

Common Gelco Chimney Cleaning Problems We Solve in Crestline
After years of working on Gelco units up here, we’ve seen the same five issues show up time after time. Each one has a Crestline-specific cause behind it.
- Cracked firebox panels and deteriorated refractory brick. Rapid heating and cooling cycles during Crestline’s long winters, October through April, stress the panels in Gelco GA and GB series fireplaces. A cabin that sits at 28 degrees overnight and gets a hot fire at 6 a.m. every day for five straight months will eventually crack something. We carry replacement refractory panels for the common Gelco sizes.
- Rust and corrosion on exterior metal components. Snowmelt and freeze-thaw cycles at 4,500 to 5,000 feet are brutal on caps and dampers. We regularly pull Gelco dampers from Crestline chimneys that are rusted into place. When water gets past a failed cap and sits on a cold damper plate, rust is just a matter of time.
- Clogged spark arrestors and screens from pine needles. Every Crestline property with a pine or cedar canopy has this problem. Needles drop all spring, gather on the cap, and block the screen. Draft goes bad, smoke rolls back into the room, and the homeowner thinks the fireplace is failing. Half the time it’s just a choked screen. We clear it during the sweep and check whether the cap is the right size for the flue.
- Failed gaskets and warped doors on gas inserts from second-home cycling. A lot of Crestline homes are weekend cabins. The Gelco direct-vent insert sits cold for two weeks, gets fired hard on a Friday night, then sits cold again. The repeated expansion and contraction wears out door gaskets faster than continuous use would. If you smell gas or see soot around the glass, that’s usually the gasket.
- Glazed creosote from high-pine burning. Pine is what everyone burns up here, and pine builds creosote fast. By February, the flue walls can glaze over with a hard, tarry layer that won’t come off with a standard brush. We use mechanical removal methods for glazed creosote, and it’s one of the most common reasons Crestline homeowners call us mid-winter.
Gelco Service in Crestline: What Local Conditions Mean for Your Equipment
Here’s the thing about Crestline that most chimney companies don’t talk about. The 92325 ZIP is full of 1950s through 1970s cabins around Lake Gregory and the Old Town stretch, and a lot of them still run original single-wall stovepipe and shallow Gelco fireboxes, similar to what we see with Gelco in Lake Arrowhead. Those units were built for a different era. After a few hard Crestline winters, they fail inspection for reasons that have nothing to do with how well the homeowner maintained them.
The freeze-thaw cycle here is the quiet killer. Water gets into hairline cracks in a Gelco crown or firebox panel during the day, freezes and expands overnight, and widens the crack. Do that two hundred times over a winter and a small problem becomes a structural one. Snow loading on exterior chimney stacks adds pressure. Spring pine-needle drop then clogs whatever survived. A Gelco in Crestline isn’t just dealing with one problem at a time. It’s usually dealing with three or four, all layered from October through May.
The practical upshot: the nearest hardware store in Crestline never stocks the odd-sized caps and dampers these older Gelco models need. We carry truck stock of the common Crestline diameters because we got tired of driving down the mountain for a part. If you own one of these cabins, we’ll bring what you need on the first visit.
Gelco Models & Products We Service in Crestline
We service the full range of Gelco models found in Crestline homes. That includes the GA series wood-burning fireplaces, the GB series factory-built units, ZC zero-clearance inserts, and Gelco direct-vent gas fireplaces. Each has its own failure profile, and we treat them accordingly.
Our parts approach is straightforward. OEM where it makes sense, quality aftermarket where an older unit needs a spec that Gelco no longer produces. We’ll never put an undersized cap or a mismatched gasket on your unit just because it was what we had in the truck. We stock the common Crestline sizes so you’re not waiting a week for a part to ship while your fireplace sits unusable.

AfterGelco Service Pricing in Crestline
A standard Gelco chimney cleaning in Crestline runs $175 to $250 for a typical single-story cabin with one flue. When we add glazed creosote removal, which is common given the pine burning up here, plan on $250 to $400 depending on severity. Cap replacement runs $300 to $550 installed depending on the flue size, and firebox panel repair starts around $250 per panel including the refractory material.
What drives cost at this elevation is access and condition. Steep roofs and snow on the ground add time. A second-story exterior stack with a stone veneer chase is slower work. A flue that hasn’t been cleaned in five years takes longer than one that’s on a schedule. Our estimates are free, and we’ll show you what we found before any work is approved. Call (833) 467-7685 and we’ll talk numbers specific to your Gelco and your roofline.

FAQs – Gelco Chimney Cleaning in Crestline
Every year, and for full-time Crestline burners we often recommend a mid-season check if you’re burning pine daily from October through April. The long heating season builds creosote faster than a flue down the hill would see, and glazed creosote from pine is harder to remove once it forms. If you’re a weekend-only cabin owner, an annual sweep before the first fire of the season covers you. Give us a call at (833) 467-7685 and we’ll put you on a schedule that matches how you actually burn.
In Crestline, the answer is usually a clogged spark arrestor covered in pine needles, a failed cap letting debris into the flue, or glazed creosote narrowing the passage enough to kill the draft. On Gelco units specifically we also see warped door gaskets on gas inserts that let combustion gases leak into the room. We’ll diagnose the actual cause and show you the evidence before recommending a fix. Call (833) 467-7685 for a free estimate and we’ll sort it out.
Yes, if the firebox structure is otherwise sound, replacing a cracked refractory panel is a common repair we do on Crestline Gelco GA and ZC units. If the cracking is widespread or corrosion has compromised the unit, we’ll tell you replacement is the safe move and explain why. We use OEM Gelco panels or quality aftermarket equivalents that meet original specs. We had a job near Lake Gregory where a GA series fireplace had a glazed flue, a rusted-through cap, and a cracked firebox panel. We removed the creosote, replaced the cap with a custom-fit multi-flue model from truck stock, and repaired the panel, and the homeowner was burning safely before the next snow. Call (833) 467-7685 and we’ll look at yours.
We do. The 1950s through 1970s cabins around Lake Gregory and Old Town Crestline, like those needing Gelco service in Muscoy, often need odd-sized caps and dampers that the local hardware store doesn’t stock. We carry truck stock of the common Crestline diameters, so you’re not waiting on a shipment. OEM when it’s available, quality aftermarket when it’s the right fit. Call (833) 467-7685 and tell us the model and year, and we’ll tell you what’s realistic.
A Level 1 inspection is a visual check of the accessible parts of the chimney when nothing has changed since the last service. A Level 2 inspection is a more thorough evaluation using camera equipment, and it’s required after a property sale, a chimney fire, or any major change to the system. For Crestline buyers picking up a cabin, a Level 2 is the right call before the first fire of the season. Call (833) 467-7685 and we’ll book the right one.
