Fast, Reliable Chimney Repair Across Gunbarrel
If your chimney has cracked tile, loose mortar, or a firebox that smokes back into the room, we handle the repair in Gunbarrel from inspection to finish. Gunbarrel’s housing went up mostly in the late 1970s and 1980s, so the chimneys here have had decades of hard use and freeze-thaw winters behind them. We work in chimneys only – it’s all we do – and our technicians have up to 13 years of experience reading exactly these problems. Call (855) 632-3564 to book a free estimate. We answer 24/7, with fast dispatch from 7am to 7pm.
Why Gunbarrel Homeowners Call Chimney Sweep Greeley for Chimney Repair
Gunbarrel is a specific kind of place to own a chimney, and it helps to work with technicians who understand that. Because Gunbarrel sits in unincorporated Boulder County, Boulder’s no-burn ordinance doesn’t automatically apply out here – which means a lot of homes burn far more wood, far more often, than a house two miles west inside the city. That single fact changes what we find and how often a flue needs attention.
We keep our work in the chimney trade alone: sweeping, inspection, and repair. No handoffs to a general handyman, no split focus across unrelated home services. When a Level 2 inspection finds a problem, the same specialists who found it plan the fix and the same crew installs it. From inspection to repair, handled by the same specialists.
Homes off Lookout Road and Spine Road are a big part of what we see, along with the townhome and condo clusters where flues share a chase. We know how these chimneys were built and what goes wrong with them after forty winters. Our reputation around Gunbarrel is built on telling people plainly what’s wrong, what it costs, and what can wait.

Chimney Cap Replacement in Gunbarrel
Chimney Cap Replacement in Gunbarrel usually comes up when a foothills wind event lifts or warps a cap that was never anchored for gusts. A cap does two jobs here: it keeps water and animals out of the flue, and a properly designed one helps the flue draw against the downdrafts that roll off the hills near Boulder Reservoir. If your cap is missing, rusted through, or banging loose, it’s one of the cheaper fixes we make and one of the more valuable.
A typical chimney cap replacement in Gunbarrel runs $185 to $450, with the upper end covering a larger multi-flue cap or a custom-fit stainless model. We size the cap to the flue, not the other way around, and we’ll tell you if the existing cap just needs re-securing.
Draft-Friendly Caps for Windy Lots
On lots along the foothills edge, smoke rolling back into the living room is often a cap and downdraft problem rather than a fire problem. A draft-improving cap paired with a top-sealing damper usually resolves it. We source caps through Famco and Olympia Chimney, both built for real weather.
Getting the Cap Sized Right
A cap that’s too small chokes the flue; one that’s too loose doesn’t protect anything. We measure the flue opening and match the cap so it seals correctly and still lets the chimney breathe.
Chimney Liner Installation in Gunbarrel
Chimney Liner Installation in Gunbarrel is the repair we do more than any other, because so many homes still run on the original clay-tile flue from the 1970s. After decades of heating and freeze-thaw cycles, that tile cracks and spalls, and once it does, creosote and heat can reach the framing around the chimney. A stainless liner sized to the appliance and insulated to protect the surrounding masonry is usually the right correction.
A typical chimney liner installation in Gunbarrel runs $2,400 to $5,800, depending on flue height, liner diameter, insulation, and whether it’s a flexible or rigid system. DuraFlex flexible liners handle the offset flues common in these homes; Copperfield rigid systems suit straighter runs. The written estimate sets the final price.
When a Liner Is Really Needed
We don’t recommend relining on a hunch. A camera inspection shows the cracks and gaps, and you see the footage before anything is quoted. If the tile is sound, we say so and leave it alone.
Restorative Repair as an Alternative
Not every flue needs a full liner. For some chimneys, HeatShield restorative repair seals cracks in the existing flue from the inside – a less invasive option than full relining. We’ll tell you when that path fits and when it doesn’t.
Trusted Brands We Service in Gunbarrel
We install and service products from a vetted portfolio of professional-grade chimney brands: DuraFlex and Copperfield for liner systems, Olympia Chimney and Famco for caps and venting, HeatShield for restorative flue repair, and Gelco for cover solutions. These are the materials chimney technicians trust, and they’re what we reach for on a Gunbarrel job because the wind and the freeze-thaw here punish anything lesser. We source to your job rather than carrying stock – which keeps turnaround quick and means we can match the right system to your chimney type instead of forcing a one-size answer.
Common Chimney Repair Problems We See in Gunbarrel Homes
- Cracked clay-tile flue liners. Forty-plus years of heating and Front Range freeze-thaw open up cracks in the original tile, and those cracks let creosote and heat reach the wood framing. A camera inspection is the only honest way to know the tile is sound.
- Glazed creosote from wood-stove primary heat. Because Boulder’s burn restrictions don’t apply in unincorporated Gunbarrel, many fireboxes here run through several cords a winter. That loads the flue with second- and third-degree creosote a brush can’t fully clear, and it shortens the safe sweeping interval.
- Chinook downdrafts and warped dampers. Windy foothills lots, especially near Boulder Reservoir, push smoke back into living rooms through a damper that’s warped or gone. A top-sealing damper plus a draft-improving cap is the usual fix.
- Crown and masonry freeze-thaw damage. The exterior crown and mortar joints take the snowmelt-then-freeze cycle every year, so repointing, waterproofing, and crown repair come up often on these 1970s and 1980s homes.

FAQs About Chimney Repair in Gunbarrel
Mostly yes – Boulder’s no-burn ordinance doesn’t automatically apply in unincorporated Gunbarrel, though county rules and any burn restrictions on a given day can still. That freedom is exactly why wood-burning here is heavier, and why your flue needs more attention than a city fireplace. Call (855) 632-3564 and we’ll walk you through what your burning pattern means for your chimney.
If your wood stove is your primary heat, plan on sweeping more often than the once-a-year rule for occasional fireplace use – many wood-stove-primary homes here need it every few months of the burn season. Heavy burning loads creosote fast, and glazed buildup is the fire hazard. Call (855) 632-3564 to set an inspection and get a real read on your flue.
Smoke rolling back is usually a downdraft problem, not a fire problem – Chinook winds off the foothills push air down the flue and overcome a warped or missing damper. A top-sealing damper paired with a draft-improving cap typically fixes it. Call (855) 632-3564 and we’ll assess your cap and damper.
Not always, but it’s the most common repair we make here because that original tile cracks and spalls after decades of heating and freeze-thaw. A camera inspection shows whether the tile is intact or whether a stainless liner is warranted. You see the footage before we recommend anything – call (855) 632-3564 to book it.
First-degree creosote is the light, flaky soot a brush removes easily; third-degree is the glazed, hardened layer that a brush won’t clear and that’s the real fire risk. Wood-stove-primary homes in Gunbarrel build up third-degree glaze faster than city fireplaces, so the sweep often needs a chemical treatment first. Call (855) 632-3564 to find out what stage your flue is at.
