Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Longmont, CO
If you own an older home in Longmont, the odds are good your chimney was built before anyone thought about what a modern flue needs. The city sits at roughly 5,000 feet on the Front Range, with cold winters that push fireplaces into heavy use and temperature inversions in the St. Vrain Valley that hold wood smoke near the ground. That combination is why chimney repair in Longmont so often starts with a cracked clay-tile liner and ends with a conversation about safety. We handle the whole flue, from the first cleaning to the structural fix. Call (855) 360-7080 to book a visit. We answer 24/7 and dispatch from 7am to 7pm, Sunday through Friday, closed Saturday.
Why Longmont Homes Are Different
Longmont has two housing stories running side by side, and it changes the trade entirely. Old Town and the historic core hold early-1900s Victorians and bungalows with original brick masonry chimneys and clay-tile liners. Many of those liners are at or past their service life. East and south Longmont subdivisions built in the 1990s and 2000s mostly went in with prefabricated metal fireplaces and insulated flue pipes, which need a different kind of inspection and a different set of tools.
That means one Longmont technician routinely services century-old masonry that may need relining and factory-built units that need only flue-pipe checking, often on the same afternoon. Add the cold, dry Front Range climate and you get a specific failure mode: freeze-thaw swings crack clay tile in the older brick homes, a problem the prefab-lined houses to the east simply do not have. Before we climb anything, the neighborhood tells us what we’re likely to find.
Spring matters here too. The St. Vrain corridor sends cottonwood fluff and wind-driven debris into caps and flues between seasons, and dry, windy weather drives downdrafts back down the flue. A chimney that drafts well in January can puff smoke in April.

Our Main Longmont Services
These are the two services Longmont homeowners call us about most, and they address very different risks in the house.
Chimney Sweep in Longmont
A sweep is a cleaning and an inspection at the same time. We remove the creosote that builds up fast during Longmont’s cold winters, then check the flue, cap, crown and flashing while we’re up there. In Old Town’s older brick homes, that check is where we find cracked clay tile before it becomes a real problem. You get photos of what we found, not a verbal list. Work that can safely wait is said plainly, and nothing gets recommended without camera evidence you can see. Book a Chimney Sweep in Longmont before the burning season starts.
Dryer Vent Cleaning in Longmont
This is the hidden fire hazard most chimney-only companies won’t touch. Lint accumulates in the vent run the same way creosote accumulates in a flue, and the fix is straightforward: we clear the full run, check the outside termination, and confirm the vent isn’t crushed behind the dryer or sagging in the wall cavity. In Longmont homes where the dryer sits against an exterior wall, the run is short and simple. Where it climbs through a second floor, it needs more attention. We include Dryer Vent Cleaning in Longmont as a core service because it belongs in any honest home-safety conversation.
Chimney Repair in Longmont
Chimney repair in Longmont usually begins with one of two discoveries: a clay-tile liner cracked by decades of freeze-thaw, or flashing that has pulled away from a brick chimney on a century-old roof. The dry, windy Front Range springs are hard on masonry and on every joint at the roofline. We handle Chimney Repair as a full lifecycle job, which means defects found during a sweep get resolved without you scheduling a second contractor. Our technicians have up to 9 years of experience, and we name the brands we install because you deserve to know what’s going into your home.
Chimney Liner Installation
Signs you need it
You need a liner when a camera inspection shows cracked, spalling or missing clay tile, or when an old flue was never sized correctly for the appliance now connected to it.
What it costs in Longmont
A chimney liner installation in Longmont typically runs $1,800 to $4,500, and the written estimate sets the final price.
How we do it
We camera the flue first, size the liner to the appliance, then install a DuraFlex flexible liner system with proper insulation and a top plate, and finish with a test burn and photos.
Chimney Crown Repair
Signs you need it
A cracked, flaking or visibly tilted crown lets water straight into the masonry, so it’s the first thing we check on an older Longmont chimney.
What it costs in Longmont
Crown repair in Longmont is typically $350 to $900, depending on how much of the crown is rebuilt versus sealed, with the final price in the written estimate.
How we do it
We chip out the failed section, form a proper overhang so water sheds past the chimney walls, pour or trowel the new crown, and let it cure before the flue goes back into use.
What Chimney Repair Costs in Longmont
| Item | Typical range in Longmont |
|---|---|
| Chimney liner installation | $1,800 – $4,500 |
| Chimney crown repair | $350 – $900 |
| Chimney cap installation | $250 – $650 |
Do I really need a new liner in Longmont?
Not always. A cracked clay liner in an older Longmont chimney sometimes qualifies for HeatShield resurfacing instead, which restores the flue from the inside without a full reliner. We show you the camera footage and tell you plainly when the cheaper repair is safe.
Can you fix what you find during a sweep?
Often, yes. When a sweep turns up a failed cap, damaged flashing or a crown problem, we can resolve it during the same visit, which is why we do repair and cleaning under one roof in Longmont. Call (855) 360-7080 for a free estimate.
Brands We Service in Longmont
We work with a curated roster of professional-grade industry brands: DuraFlex for flexible liner systems, HeatShield for liner resurfacing, and Famco and Copperfield for caps and related components. Professional-grade materials, transparent process, no mystery parts. We don’t stock parts locally, so if a specific component is needed we’ll tell you the turnaround when we price the job. You can see the full roster on our brands page.

In Longmont, price climbs with access and with masonry condition: a chimney on a steep-pitch historic roof takes longer to reach, and a crown that needs a full rebuild costs more than one that needs sealing. Older Old Town brick chimneys with deteriorated mortar often need more than one repair at once. Everything is flat-priced from the written estimate, swept by your city’s building department if a permit applies, and nothing gets added afterward.
