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 Gunbarrel, CO
We provide independent Gelco service across Gunbarrel, and the one thing that makes our Gelco work here different is that we treat your insert and its flue as a single system, not a box that gets swept and forgotten. Our technicians have up to 13 years of experience with Gelco fireplace inserts, prefab fireboxes and the caps and dampers that keep them drafting right. Whether you’re off Lookout Road or in a townhome cluster near Spine Road, we’re ready to take a look. Call (855) 632-3564. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Gunbarrel Residents Choose Us for Gelco Service
We work in chimneys only – it’s all we do. That matters with Gelco equipment, because a Gelco insert from the late 1970s or 1980s fails in ways that a general handyman won’t recognize: a slightly warped baffle plate, a damper pivot that’s seized just enough to stay half-open, a firebox panel that’s spalled behind the brick face. We’ve watched those failure patterns repeat across Gunbarrel homes long enough to know what we’re looking at within the first few minutes of an inspection.
We’re an independent shop. That means we diagnose honestly, recommend the repair that fits your insert, and don’t run a manufacturer’s script. When we source parts, we pull from professional-grade brands chimney technicians trust, including Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco and Copperfield. Scheduling is straightforward: you call, we book a window, and we show up with the tools for the job.

Common Gelco Chimney Cleaning Problems We Solve in Gunbarrel
These are the patterns we run into most often with Gelco equipment in Gunbarrel‘s older housing stock. Each one tends to show up alongside a specific local factor.
- Warped baffle plates and sagging burn tubes. Decades of heavy winter burns in a Gelco insert distort the firebox and change how the unit drafts. In Gunbarrel, where wood inserts get burned hard through cold snaps, this shows up earlier than it would in a milder climate. We inspect the baffle, measure warpage, and replace it when it’s affecting combustion.
- Cracked or spalled firebrick and refractory panels. Repeated freeze-thaw cycles on exterior chases work on Gelco prefab fireboxes from the outside in. When a panel cracks, heat reaches places it shouldn’t. We assess whether the panel can be re-sealed or needs replacement.
- Corroded damper pivot pins and seized throat dampers. Snowmelt and Chinook-driven moisture get into the throat area over time, and the damper stops moving freely. A damper that won’t close properly bleeds heat and lets cold air down the flue. We free or replace the assembly.
- Failed direct-vent collar gaskets on Gelco gas inserts. When the gasket degrades, cold air and downdrafts push back into the living room. A gas insert that feels drafty on a windy night is usually telling you the collar seal has gone.
- Undersized caps on gusty foothills chases. Homes near the reservoir and along the foothills edge see Chinook downdrafts that shove smoke back down the flue. A cap sized for a calmer location won’t cut it. We fit draft-improving caps and top-sealing dampers matched to the chase.
Gelco Service in Gunbarrel: What Local Conditions Mean for Your Equipment
Here’s the piece that shapes almost every Gelco job we see in Gunbarrel: this community sits outside Boulder city limits, so Boulder’s wood-burning restrictions don’t automatically apply here. That means many Gelco wood inserts in Gunbarrel are still burned hard on cold nights, and they carry heavier creosote loads than the same inserts a few miles west inside the city. A home off Lookout Road with an original late-1970s Gelco factory-built insert and a clay-tile flue is a good example of what that looks like over time. Forty years of hard winter burning, no top-sealing damper, and a cap that was never sized for the gusty foothills downdrafts add up to a unit that smokes back into the room during Chinook wind events and shows a warped baffle plate or a seized damper on inspection. The fix usually isn’t dramatic: a Level 2 inspection with video, a thorough sweep, a freed or replaced damper, and a draft-improving cap sized for the chase. But the order matters, and it starts with knowing what’s actually inside the flue.
Gelco Models & Products We Service in Gunbarrel
We service the kinds of Gelco products that were common in Gunbarrel’s 1970s and 1980s subdivisions: factory-built wood-burning fireplace inserts, heat-circulating insert series, zero-clearance fireplaces with glass doors, and masonry-style prefab fireplaces with outside air kits. We also handle the caps and covers that protect them.
For parts, we use OEM Gelco components when they’re still in production for the insert body and damper assembly. For obsolete baffles, fireback panels and caps, we specify quality aftermarket equivalents that match the original dimensions and clearances. We won’t put a part in that doesn’t fit, and we’ll tell you plainly when a 40-year-old Gelco insert is at the point where a rebuild or full insert replacement makes more sense than piecemeal repair. That call belongs to you, but you’ll have our honest read on it.

AfterGelco Service Pricing in Gunbarrel
Pricing depends on what we find. A basic sweep on a Gelco insert is one number; a Level 2 inspection with video, a freed damper and a new draft-improving cap is another. We don’t quote over the phone without seeing the unit, because an aging insert off Spine Road can need very different work from one in a townhome with a shared chase. Every estimate is free and written, and the written estimate sets the final price. Nothing is recommended without camera evidence you can see for yourself, and we’ll tell you when work can safely wait. Call (855) 632-3564 for an exact quote – estimates are free.

FAQs – Gelco Chimney Cleaning in Gunbarrel
No, Boulder’s wood-burning restrictions don’t automatically apply to Gunbarrel because it’s unincorporated county land. That’s why many Gelco wood inserts here are still burned regularly and carry heavier creosote loads than units inside the city. Have yours inspected before fire season starts. Call (855) 632-3564 for an exact quote – estimates are free.
It’s usually the chimney system, not the insert body alone. Chinook downdrafts, an undersized cap, and a missing or failed top-sealing damper combine to push smoke back into the room. A draft-improving cap sized for the chase often solves it. Call (855) 632-3564 to book an inspection.
A Level 2 inspection with video is what tells you. If the flue liner is intact and only carries creosote, a sweep is enough. If the liner is cracked or spalled, or the firebox panels are failing, relining or a rebuild becomes the honest recommendation. We show you the footage before recommending anything.
A failed direct-vent collar gasket is the usual cause, letting cold air and downdrafts back into the living room. Replacing the gasket and checking the vent termination usually resolves it. Call (855) 632-3564 for an exact quote – estimates are free.
Yes. Shared-chase configurations are common in Gunbarrel’s townhome and condo clusters, and they need the same Level 2 inspection as a single-family home, plus attention to how the chase is shared. We’ll assess access and clearance before we book.
