AfterHow Much Does Fireplace Services Cost in Longmont?
Fireplace services in Longmont typically run $95-$250 for a standard chimney sweep and inspection, $350-$900 for common masonry or firebox repairs, and $2,200-$5,500 for a full flue reline with a DuraFlex flexible liner system. Smaller fixes like a damper replacement or a crown repair often land between $200 and $600. The written estimate sets the final price, and it’s always free.
We work on wood-burning and gas fireplaces across Longmont, and the pricing you’ll see below reflects what the 2026 market here actually looks like. We name the brands we install (DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, Copperfield) because you deserve to know what’s going into your home, and because specs drive cost more than anything else in this trade.
Key Takeaways
- A standard sweep and inspection in Longmont runs about $95-$250, depending on the flue and how long it’s been since the last cleaning.
- HeatShield liner resurfacing often costs far less than a full reline and can extend the life of a chimney that isn’t too far gone.
- Full DuraFlex relines land at $2,200-$5,500 because material, flue length, and liner diameter all change the number.
- Identified during the sweep, fixed the same visit: when we find a defect mid-sweep, we quote it on the spot so you’re not booking a second contractor.
- Dryer vent cleaning is $120-$220 and is a separate fire hazard worth addressing while we’re there.
Fireplace Services Cost Breakdown (2026)
Here’s what Longmont homeowners can expect to pay for each service line. These are typical ranges, and the written estimate is what actually sets your price.
| Service | Typical Range | What It Covers |
|---|---|---|
| Standard chimney sweep | $95-$250 | Brush and vacuum of the flue, firebox, and smoke chamber; visual check of the flue |
| Level 2 inspection (camera) | $150-$400 | Video scan of the flue interior; standard for recent home purchases or after a chimney fire |
| Ash pit or firebox cleaning | $80-$180 | Removing ash and debris buildup beyond a routine sweep |
| Crown repair or rebuild | $350-$900 | Sealing or replacing the concrete crown at the top of the chimney |
| Flue tile or mortar repair | $300-$800 | Repointing cracked joints, replacing spalled flue tiles |
| Damper replacement | $200-$600 | New throat damper or top-sealing damper install |
| Cap and screen install | $150-$450 | Stainless cap with animal and spark screen |
| HeatShield liner resurfacing | $1,100-$2,600 | Resurfacing a sound-but-rough flue liner without full replacement |

| Dryer vent cleaning | $120-$220 | Lint removal from the vent run, including the transition and exterior hood |
What pushes a fireplace job toward the top of a range? Flue length and shape matter most. A straight flue is quick and clean. An offset flue, a chimney with a bad cap, or a firebox that needs masonry work all add time and materials. Cracks in the flue tile are the single biggest swing factor, because a small fissure either gets patched with HeatShield resurfacing (the cheaper path) or forces a full reline. The difference between those two paths is often a thousand dollars or more, and we won’t recommend a reline when resurfacing will hold.
Materials drive the rest. A DuraFlex flexible liner is a professional-grade product; a hardware-store insert isn’t the same thing, and it usually costs you less upfront and more later. We install the real spec. Same for Gelco, Olympia Chimney, Famco, and Copperfield components, which is why our repair quotes hold up longer than a patch-and-hope fix.
What Affects Fireplace Services Pricing in Longmont
A few factors swing the cost of fireplace work here more than most homeowners expect. It’s worth understanding them before you book, because they explain why two quotes for what sounds like the same job can differ by hundreds of dollars.
- Flue condition. If the flue is sound and just dirty, you’re paying for a sweep. If the flue tiles are cracked, spalled, or missing, the repair path shifts toward resurfacing or a reline, and the price climbs accordingly. A camera inspection tells you which side of that line you’re on.
- How long it’s been since the last cleaning. A chimney that hasn’t been swept in many seasons carries heavier creosote and takes longer to clean thoroughly. Thick, glazed creosote is also a fire hazard, not just a cleanup job, so a neglected chimney often turns a routine sweep into a bigger visit. If you’re in an older Longmont home that’s gone a few years without maintenance, budget for a level 2 inspection on the first visit.
- Chimney height and roof access. Longer flues and steeper roof pitches take longer to access and work on. The foothills winds and freeze-thaw cycles along the Front Range work on masonry and crowns year after year, which is why so many local exteriors show wear earlier than the homeowner expects.
- Wood-burning versus gas. A gas fireplace insert usually needs less sweeping work than a wood-burning firebox, but the venting and gas connections need a different kind of check. Our technicians have up to 9 years of experience with both, and we’ll be straight about which type of visit you actually need.
- Which brand of repair materials you choose. Professional-tier products like HeatShield, DuraFlex, and Olympia Chimney cost more than generic parts, but they’re what hold up under temperature cycling. You’ll see that difference reflected in the estimate, and we’ll tell you exactly what goes into your chimney.
- Whether you bundle it with other work. If we’re already up on the roof for a sweep, a cap install or crown repair is cheaper to do at that moment than on a separate visit. Same logic applies to dryer vent cleaning, which we can often do on the same trip.
How to Save on Fireplace Services
The most reliable way to save on fireplace services in Longmont is to catch problems while they’re small. A cracked crown that costs a few hundred dollars to seal today can turn into a firebox rebuild if water gets behind it. That’s the money math most homeowners don’t see until it’s too late.
- Sweep before, not after, the heating season. Getting the flue cleaned before the first cold snap means you’re not competing for a slot, and you have time to price a fix at your own pace instead of on an emergency timeline.
- Ask for a level 2 inspection if you just bought the home. You wouldn’t buy a car without seeing under the hood. An inspection up front can catch a cracked flue tile you can address with HeatShield resurfacing instead of discovering mid-winter that a full reline is needed. Big difference in cost.
- Fix small masonry issues before winter freeze-thaw. A small repointing job is a fraction of a rebuild. Longmont winters are hard on exposed brick and mortar.
- Bundle drying vent cleaning with a chimney sweep. Dryer vents are the hidden fire hazard most chimney companies don’t touch. We do. Doing both on one visit keeps travel and labor down on the total.
- Get a written estimate before any work begins. Every job we quote is itemized: labor, materials, brand. You’ll see why a DuraFlex reline costs more than a HeatShield resurfacing, and you’ll be the one deciding which path fits your chimney and budget.

Frequently Asked Questions – Fireplace Services Cost
How much does a chimney sweep cost in Longmont?
A standard chimney sweep in Longmont typically costs $95-$250, depending on flue size, condition, and how many seasons it’s been since the last cleaning. If the chimney hasn’t been touched in many years or shows signs of heavy creosote, expect the upper end of that range. Call (855) 360-7080 for an exact quote. Estimates are free.
Is it cheaper to resurface a flue or replace the liner?
HeatShield liner resurfacing is almost always cheaper than a full reline, often by a thousand dollars or more. Resurfacing runs about $1,100-$2,600 for a typical job, while a DuraFlex flexible reline lands at $2,200-$5,500. The right choice depends on flue condition; we’ll tell you which path holds, not which one makes us more money. Call (855) 360-7080 to find out which is right for your chimney.
Can you come today?
We aim for same-day service when scheduling allows. Call (855) 360-7080. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. A call outside dispatch hours is booked into the next opening.
How much does fireplace repair cost in Longmont?
Common fireplace and chimney repairs in Longmont run $200-$900 for the typical fix: a damper, a crown repair, repointing, or a cap install. Full relines cost more, $2,200-$5,500. The written estimate sets your final price, and we quote it before any work begins. Call (855) 360-7080 for a free estimate.
Do I really need dryer vent cleaning, or just a chimney sweep?
You likely need both, and they solve different problems. Dryer vent cleaning runs $120-$220 and addresses a leading household fire hazard that most chimney-only companies don’t handle. Lint buildup in a vent run is invisible until it isn’t. We’ll clean the chimney and the dryer vent on the same visit so you’re not paying for two trips. Call (855) 360-7080 to schedule.
Why Fireplace Pricing Varies in Longmont
Longmont sits in a stretch of the Front Range where the weather swings hard. Warm afternoons and cold nights mean the chimney and firebox go through cycles of expansion and contraction throughout the year. That’s normal. But it’s the reason we recommend getting eyes on the flue before you assume a crack is cosmetic, and the reason a durable repair (a real masonry fix, a professional-grade liner, a proper cap) costs more upfront but ends up cheaper over the long haul.
The other factor is how neglected a chimney has been. If you’ve just moved in and the previous owners didn’t leave records of when they last had a sweep, treat the first visit as an inspection and a cleaning in one. If we find a defect, we’ll quote it on the spot. Identified during the sweep, fixed the same visit. No need to schedule a second contractor for the repair.
We serve all of Longmont and the surrounding parts of the Front Range, and we’ve built our pricing around honesty rather than a range that looks low and then balloons on the estimate. Professional-grade materials. Transparent process. No mystery parts.
What Our Fireplace Services Include
Under one service line, we cover the whole lifecycle of a chimney and fireplace system. Routine sweeping keeps creosote in check and gives us a chance to catch developing problems. Chimney repair handles what years of use, weather, and neglect leave behind: crown damage, mortar joints, a flue liner that needs a HeatShield resurfacing or a DuraFlex reline. And dryer vent cleaning addresses a separate fire hazard that sits quietly in the same house, sometimes in the same chase.
The brands we install are professional-grade: DuraFlex flexible liners, HeatShield craft resurfacing, Gelco sealing materials, Olympia Chimney caps and components, Famco venting, Copperfield mortar products. You get an itemized estimate that tells you exactly which brand and which part goes into your system. That’s not a marketing add-on. It’s the difference between a fix that holds through a Longmont winter and one that cracks by spring.
If you’re not sure whether you need a sweep, a repair, or a full reline, call us at (855) 360-7080. We’ll talk it through and quote it honestly before any work begins. Estimates are free.

- Sarah Rhodes"Drop cloths everywhere, HEPA vac, and not a speck of soot on the carpet. I'd been dreading the mess for nothing."
