Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Fireplace Services for Denver Homeowners
Our fireplace services in Denver typically cover inspection, repair, and conversion of gas and wood-burning units, with most jobs completed in a single visit and priced between $195 and $875 depending on the work needed. At Level Two Chimney Denver, we’ve inspected and serviced more than 38,000 fireplaces and chimneys since 2009, and every job starts with a written price before any work begins. Call us at (720) 674-7312 for a free estimate, or keep reading to see exactly what we check, what it costs, and how our process works.
Denver’s altitude, dry climate, and temperature swings put unusual stress on fireplace components. We see cracked firebox refractory panels in Park Hill homes from thermal cycling, failed gas valves in Stapleton townhomes after freeze-thaw seasons, and damper corrosion in Wash Park bungalows where original cast iron has seen 80 years of use. Our technicians arrive uniformed, background-checked, and with a license number you can verify. You’ll get a text when we’re on the way, a camera inspection of the flue and firebox, and a documented photo record before we leave. That’s Clause 4 of the Haven Standard, and we’ve done it on every single job since 2009.

What Our Fireplace Services Include
Gas Fireplace Service
Gas fireplace service covers inspection and repair of the burner assembly, pilot light, thermocouple, gas valve, and venting system. In Denver, we frequently find debris-blocked vents in newer builds near Lowry and failing millivolt generators in 1990s-era Heat-N-Glo units across Cherry Creek. We pressure-test the gas line, check flame pattern and carbon monoxide output with a combustion analyzer, and inspect the vent termination for proper clearance. If your gas fireplace won’t stay lit, smells of raw gas, or produces soot on the glass, we’ll diagnose it with the camera and written scope in hand before quoting any repair.

Wood Burning Fireplace
Wood burning fireplace service addresses the firebox, smoke chamber, damper, and flue liner as an integrated system. Denver’s EPA burn restrictions and frequent inversion days mean your fireplace needs to draft efficiently or it smokes back into the room. We measure flue draft pressure, map the smoke chamber with our camera, and classify creosote buildup by type. Class III glazed creosote, common in Highlands Ranch homes where owners burn unseasoned pine, requires mechanical removal and chemical treatment. We document everything with photos and explain whether the condition is a maintenance item or a safety concern that affects your next fire.

Fireplace Insert
Fireplace insert service covers both the insert unit itself and the connection to your existing chimney flue. Inserts are popular in Denver’s 1920s bungalows and mid-century ranches where the original fireplace is inefficient but the masonry is sound. We inspect the liner connection for gaps, check the blower motor and electrical components, and verify the unit is listed for your chimney’s dimensions. A poorly connected insert in a Capitol Hill Victorian can spill carbon monoxide into wall cavities. We use our camera to inspect the full liner length and provide a written assessment of whether the installation meets manufacturer clearance requirements.

Damper Repair
Damper repair fixes the metal plate that seals your fireplace flue when not in use. In Denver, we replace rusted throat dampers in pre-1950s homes from Congress Park to Montclair, and install top-sealing dampers with stainless steel cables in homes where the original throat damper is inaccessible. A stuck-open damper wastes 20% or more of your heating budget through the chimney. A stuck-closed damper traps smoke and carbon monoxide in your living space. We test operation, inspect the frame for cracks or corrosion, and quote replacement only when repair isn’t practical. Top-sealing dampers also keep out rain, snow, and the squirrels common in Denver’s mature tree canopy.

Firebox Repair
Firebox repair addresses cracked or spalling refractory panels, deteriorated mortar joints, and heat-damaged steel units. Denver’s dry climate accelerates thermal expansion damage. We see hairline cracks in factory-built fireboxes after just 10-15 years of use, and we see original Rumford-style brick fireboxes in Country Club homes with mortar joints eroded to powder. Small cracks can be patched with refractory cement. Larger damage requires panel replacement or steel firebox rebuilding. We show you the camera footage, explain the temperature rating of the repair material, and tell you plainly whether the firebox is safe for the next burning season or needs immediate attention.

Fireplace Conversion
Fireplace conversion changes your fireplace from wood-burning to gas, or from gas back to wood, or to an electric insert. Denver’s air quality regulations and the convenience of gas push many homeowners toward conversion, especially in newer neighborhoods like Stapleton and Berkeley where time is scarce and wood storage is impractical. We assess your chimney’s compatibility with the new fuel type, verify adequate flue sizing per NFPA 211, and handle the gas line extension or electrical circuit if needed. Every conversion includes a new inspection certificate and updated documentation for your homeowner’s insurance. We do not perform conversions without a full Level 2 inspection first. Clause 4 of the Haven Standard requires it.

Brands We Service for Fireplace Services

We’ve serviced hundreds of HeatShield units in Denver metro homes, particularly the factory-built fireplaces common in 1980s and 1990s construction from our fireplace services in Aurora to Lakewood. We stock HeatShield refractory mortar and their cerfractory foam for smoke chamber parging, and we know the clearance requirements for their listed repair systems. For gas fireplace components, we regularly source DuraFlex liners and venting products through Haven’s buying network, keeping customer prices honest on materials that other companies mark up 40% or more. DuraFlex’s corrugated stainless steel liners handle the thermal expansion we see in Denver’s altitude-affected draft conditions better than smooth-wall alternatives in many applications.
We also work with Gelco chimney caps and Olympia Chimney supply products for top-end repairs and replacements. Gelco’s stainless steel caps with integrated dampers solve the common Denver problem of a failed throat damper in a chimney with no accessible smoke shelf. Olympia’s insulated liners are our choice for tight flue installations in historic Denver homes where the original clay liner is too damaged for HeatShield resurfacing. Whether you have HeatShield, DuraFlex, Gelco, Olympia, or any other make, we can service it, repair it, or convert it. We provide a Free Second Opinion on any competitor’s written estimate if you want to compare our scope and pricing.

- Soot buildup on gas fireplace glass. Clean-burning gas should produce minimal soot. If your glass blackens within a week of cleaning, the air-fuel mixture is off, the burner ports are clogged, or the venting is restricted. This is a carbon monoxide risk. We test combustion with a digital analyzer and clean or adjust until the flame burns blue with minimal CO output.
- Smoke entering the room when you light a wood fire. This means failed draft, which can come from a cold flue, blocked chimney, damaged liner, or competing negative pressure from your HVAC system. In Denver’s tight new construction, we see this frequently in winter when the whole-house fan or range hood overwhelms the fireplace draft. We measure pressure differentials and inspect the flue with our camera to find the cause.
- Crumbling brick or mortar in the firebox. Spalling brick and deteriorated mortar joints expose surrounding combustibles to direct heat. In Denver’s older homes, we’ve found original lime mortar that’s turned to sand after 80 years of heating cycles. We classify the damage, show you the photos, and quote repair with materials rated to 2,000°F or higher.
- Damper that won’t open fully or close completely. A stuck damper is more than inefficient. If it won’t open, smoke and CO back up into your home. If it won’t close, you’re heating the outdoors all winter. We see rusted pivot pins in Denver’s pre-war housing stock and warped frames from over-firing. We repair what we can and replace what we can’t, with the price in writing first.
- Gas odor when the fireplace is off or on. Any gas smell demands immediate attention. It can indicate a leaking valve, cracked fitting, or deteriorated flex line. We do not recommend troubleshooting this yourself. Our technicians carry electronic leak detectors calibrated to 10 ppm sensitivity, and we isolate and test every joint from the shutoff valve to the burner assembly.
Our Fireplace Services Process - Step by Step

- 1
Schedule and confirm. Call (720) 674-7312 and you’ll reach a live person, 24 hours a day. We book a window that works for you, send a confirmation text, and text again when your technician is en route with a photo and name. No anonymous arrivals, no four-hour waits without updates. That’s Haven Standard Clause 2: Arrive on schedule.
- 2
Level 2 inspection with camera documentation. Your technician arrives uniformed, introduces themselves, and begins with a visual inspection of accessible components. Then the camera goes down the flue, through the smoke chamber, and into the firebox. We record footage and still images of every surface. In Denver’s competitive real estate market, this documentation protects your sale price and your insurance claim if you ever need one. Clause 4 of the Haven Standard requires this photo record on every job. We’ve done it since 2009.
- 3
Written diagnosis and price before any work. We show you what the camera found, explain it in plain terms, and deliver a written scope with a fixed price. No open-ended hourly rates. No surprises after the work starts. If you decline the work, you pay only the inspection fee. Haven Standard Clause 1, H.A.V.E.N. “Have it in writing,” governs this step. We invented this practice in 2009 because we were tired of the industry’s bait-and-switch reputation.
- 4
Repair or service with verified materials. Once you approve the scope, we complete the work with materials sourced through Haven’s buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. Your technician documents the completed work with after photos, test results, and readings. Gas fireplaces get combustion analysis printouts. Wood fireplaces get draft pressure readings and creosote classification.
- 5
Written warranty and 365-Day Done Right Promise. You receive a completed work summary, photo documentation, and written warranty before we leave. The 365-Day Done Right Promise means if anything we serviced needs correction within a year, we make it right at no charge. This is stamped on every job, not offered as an optional upgrade. If you received a competing written estimate, our Free Second Opinion stands ready for comparison.
How Much Does Fireplace Services Cost in Denver?
A typical gas fireplace service in Denver runs $195-$295 for inspection, cleaning, and standard component testing, so you can see how much fireplace services costs for basic maintenance. Wood burning fireplace inspection and sweep ranges from $245-$345 depending on creosote class and accessibility. Fireplace insert service with liner inspection runs $295-$425. Damper repair or replacement ranges $285-$575, with top-sealing dampers at the higher end due to roof access requirements. Firebox repair starts around $325 for refractory panel replacement and can reach $875 or more for full steel firebox rebuilding in severe cases. Fireplace conversion, including gas line extension and new unit installation, typically runs $2,800-$4,500 depending on fuel type and chimney modifications needed.
Several factors move these prices. Roof height and pitch affect access time. Denver’s older homes often have unlined chimneys or damaged clay liners that must be addressed before conversion. Custom fireplace dimensions require special-order parts with longer lead times. We quote every job in writing before starting, and we explain which factors apply to your specific situation. You can avoid overpaying by getting a camera-documented inspection that proves what work is actually needed. We’ve seen competitors in Denver recommend $3,000 liner replacements for flues that only needed a $400 HeatShield resurfacing. Our photo evidence lets you see the difference for yourself.
Every free estimate includes the Level 2 camera inspection, written scope, and fixed price. If you have a competitor’s written quote, we offer a Free Second Opinion to compare scope and materials. Materials sourced through Haven’s buying network from DuraFlex, HeatShield, Gelco, and Olympia Chimney keep our pricing honest without the retail markup common in this industry.
