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 Fort Collins, CO
We provide independent Gelco service across Fort Collins, from Old Town bungalows to the newer builds along the city’s south and west edges. What makes our Gelco work here different is the order we do it in: we clear creosote, repair the crown and cap, then check the firebox, because Fort Collins sun and wind wear out the outside of a chimney before most homeowners notice anything inside. For Gelco owners that sequence matters. A cracked crown quietly lets water into the same firebox panels that freeze-thaw cycles are already stressing.
Call (855) 632-3564 to book an inspection or a sweep. We answer 24/7, and dispatch runs 7am to 7pm, Sunday through Friday.

Why Fort Collins Residents Choose Us for Gelco Service
Gelco equipment shows up in every kind of home here: original fireplaces in the older brick neighborhoods, retrofitted inserts in mid-century ranches, and gas units in the subdivisions built through the 1990s and 2000s. We service those units and install quality parts that fit them, sourced from professional-grade brands including DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. When a Gelco part is still made, we look for the original component so the fit and the safety rating match what the chimney was designed around. When a unit is old enough that the part is gone, we use a quality aftermarket piece and tell you plainly why.
We work in chimneys only. That single-trade focus is why a Gelco firebox panel, a damper assembly, or a direct-vent termination doesn’t surprise us. Our technicians have up to 13 years of experience, and they spend all of it on flues, fireboxes, and venting. Scheduling in Fort Collins is straightforward: you describe what the fireplace is doing, we book the right visit, and you get a written estimate before any repair starts.

Common Gelco Chimney Cleaning Problems We Solve in Fort Collins
Five issues account for most of the Gelco work we do in Fort Collins. Each one has a local cause behind it.
- Cracked firebox panels in Gelco 2000 Series units. Fort Collins swings above and below freezing repeatedly through winter, and that freeze-thaw cycle opens hairline cracks in firebox panels. Small cracks grow, and once they do, combustion gases have a path around the liner instead of up it.
- Damper mechanisms stuck from creosote and no lubrication. A damper that grinds or won’t seat fully is usually choked with creosote and dried out from years of heat. In homes where the fireplace is a backup heat source, the damper gets worked hard and the buildup comes faster.
- Liner deterioration in Gelco 3000 Series from wind-driven debris. Fort Collins wind knocks limbs and grit loose, and some of it lands on the cap and works its way down. Impacts and abrasion wear the liner surface over time, which is the kind of damage a Level 2 inspection is built to catch.
- Pilot assembly corrosion in Gelco gas inserts. The semi-arid air plus wide temperature swings corrode pilot components, and a corroded pilot shows up as a unit that lights reluctantly or smells off. We clean or replace the assembly and check the venting while we’re there.
- Heavy creosote from incomplete combustion. Smoky odors, hard-to-light fires, and a glass door that soots up quickly all point to creosote loading in the flue. A thorough sweep clears the hazard; a Level 2 inspection tells you whether the firebox or liner caused it.
If you’re noticing any of these, don’t run the fireplace until it’s been looked at. Call (855) 632-3564 for a free estimate.
Gelco Service in Fort Collins: What Local Conditions Mean for Your Equipment
Fort Collins sits in a mountain-shadow valley with intense sun and dry air, and the combination cracks mortar crowns earlier than most homeowners expect. Add the high winds that work caps loose, and you get a chimney that looks fine from the driveway while water is finding its way in at the top. That water lands on Gelco firebox panels already stressed by freeze-thaw cycles, which is why so many Gelco units here need crown repair and cap replacement alongside a standard cleaning, not after it. Walk through Old Town and you can see it: original 1920s brick chimneys with deteriorating mortar joints that need repointing before the crown and cap work will hold. In those homes the chimney is often the backup heat source, so the whole system gets used hard through cold snaps. Our advice is to book the sweep and the inspection before October, while there’s still time to repair what the inspection finds.
Gelco Models & Products We Service in Fort Collins
We service Gelco fireplaces and inserts, including the Gelco 2000 Series, the Gelco 3000 Series, Gelco Heat & Glo units, and Gelco Direct Vent systems. Each one has its own failure pattern and its own part requirements, so the visit starts with identifying exactly what’s in your chimney before anything is ordered or replaced. On the parts side, we source original components for Gelco models still in production so fit and safety match the unit’s design, and quality aftermarket parts for units that are out of production. We also install liner and venting systems from DuraFlex and Copperfield, handle restorative flue repair with the HeatShield system, and use Famco and Olympia Chimney products for venting and caps. Repair versus replacement gets weighed honestly: if a repair keeps the unit safe and reliable, that’s what we recommend.
We’re an independent service provider. We’re not affiliated with or authorized by Gelco, and we don’t claim to be.

AfterGelco Service Pricing in Fort Collins
Pricing is set per job by the written estimate, and the estimate is free. What drives the number is what the inspection actually finds: how much creosote is in the flue, whether the firebox panel is cracked, whether the crown and cap need repair, and which parts the unit requires. A straightforward sweep on a well-maintained fireplace costs far less than a job that includes panel replacement and repointing. You see the camera inspection and the photo report before any repair is approved, so you’re deciding on evidence rather than a technician’s word. And if something can safely wait, we say so.

FAQs – Gelco Chimney Cleaning in Fort Collins
Once a year is the right rhythm for most Fort Collins homes, and before the first cold snap if the fireplace is a backup heat source. The dry, windy, high-altitude climate here builds creosote fast, so an annual sweep catches it before it becomes a fire risk. Call (855) 632-3564 to get on the schedule.
Yes, in most cases a cracked firebox panel can be replaced rather than condemning the whole unit. We identify the panel, source a component that fits the model, and perform a Level 2 inspection afterward to confirm the liner wasn’t affected by the same heat and stress. Call (855) 632-3564 for an assessment.
A strange smell after windy weather usually means a loose or damaged cap is letting wind-driven debris and moisture into the venting, or the pilot assembly is corroding. Both are common here because Fort Collins wind works caps loose and the dry air corrodes pilot components. Call (855) 632-3564 and we’ll take a look.
A Level 2 inspection is the right call after a hailstorm. Hail and wind-driven debris can crack the crown, dent the cap, and damage the liner in ways you can’t see from the ground, and a Level 2 inspection with a camera documents all of it. Call (855) 632-3564 to book one.
Conversion depends on the specific unit and its venting, so it needs an inspection before anyone answers yes. Some wood-burning fireplaces can take a gas insert with the right liner and venting; others can’t safely. We’ll tell you which yours is, in plain terms. Call (855) 632-3564 to start with an inspection.
