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.
HeatShield Fireplace Services in Denver: What to Know First
We provide independent HeatShield fireplace services in Denver for gas fireplaces, wood-burning units, inserts, dampers, fireboxes, and conversions. Most HeatShield jobs are diagnosed, quoted in writing, and completed within one to three business days. You’ll see a written price before we start, camera footage of what we found, and a documented record when we’re done.
This page is for Denver homeowners who already know they have HeatShield components in their fireplace system and need someone who can name the part, show you why it’s failing, and fix it without guessing. We’re not affiliated with HeatShield Corporation. We’re an independent service provider with sixteen years of documented chimney and fireplace work across Denver, from the Capitol Hill condos to the brick Victorians along Federal Boulevard. Call (720) 674-7312 when you’re ready to see what the camera sees.

How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner resurfacing cracks or delaminates in the smoke chamber. In Denver’s freeze-thaw cycle, the foam layer can separate from the clay flue tile beneath, especially where the smoke chamber narrows. We camera-scan to confirm delamination depth. If the substrate is sound, we prep and reapply Cerfractory Foam to manufacturer thickness. If the tile behind it is compromised, we quote a liner replacement rather than a second band-aid.
- HeatShield UL-Listed stainless liners show seam separation at the flex-to-rigid transition. The 316Ti alloy holds up well to Colorado’s dry winters, but the crimped joint where flexible liner meets rigid riser works loose after repeated thermal cycling. We find this on HeatShield’s smooth-wall systems in homes built 2015-2020, particularly in Stapleton and Highlands Ranch. We cut back to sound metal, re-secure with proper draw bands, and pressure-test the joint.
- HeatShield poured refractory smoke chamber parging slumps or voids. When the parge coat is applied too thick in one pass or cures too fast in Denver’s low humidity, you get hollow spots that collect creosote and distort draft. We remove loose material, re-parge in lifts, and verify thickness with a borescope before calling it done.
- HeatShield gas fireplace inserts suffer burner port corrosion from Front Range altitude. At 5,280 feet, the air-fuel mix runs slightly leaner than sea-level design, and the stainless burner ports oxidize faster than HeatShield’s published service intervals suggest. We clean and gauge the ports, replace with OEM or certified-matching burner assemblies from our Haven buying network, and reset the manifold pressure to Denver altitude spec.
- HeatShield damper frames warp in high-heat wood-burning installations. The cast iron frame can bow if the firebox has been overfired repeatedly, which we see in older Denver homes where owners burned pine or construction scrap. A warped frame lets heat escape up the flue when the damper is “closed.” We measure the frame with feeler gauges. If it’s within spec, we reseat the blade and adjust the linkage. If the frame is out of true, we quote a replacement damper assembly, often sourcing through Gelco or Famco when HeatShield lead times stretch past burning season.
Our HeatShield Fireplace Services Process

- 1
Call and schedule. A live person answers, checks our calendar, and books your appointment. You’ll get a text when your tech is en route.
- 2
NFPA 211 Level 2 inspection with camera. We run a chimney camera down the flue and document the full system: liner condition, smoke chamber, firebox, damper, and exterior termination. You see what we see. The camera doesn’t guess. Neither do we.
- 3
Written diagnosis and price. Before any work starts, you get a written scope, a written price, and a written warranty. Clause 1 of the Haven Standard: have it in writing.
- 4
Parts decision. We use HeatShield OEM parts when available and warranty-appropriate. When lead times or cost don’t serve you, we source quality equivalents through our Haven buying network from DuraFlex, Gelco, Olympia Chimney, Famco, or Copperfield, and we tell you exactly which part and why.
- 5
Repair and test. We complete the work, run a post-repair camera pass, test fire or pressure-check as appropriate, and clean the work area.
- 6
Documented record and guarantee. You receive photos, camera footage, and a completion report. Clause 4 of the Haven Standard requires this documentation on every job. The 365-Day Done Right Promise applies from day one.

Why Denver Homeowners Call Level Two Chimney Denver for HeatShield Work

We’ve completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price before work started and a documented record when finished. Corrine Halstead trained in combustion venting and liner systems at Apex Technical School in Manhattan before bringing that documentation habit west. Her crew has worked HeatShield systems from the townhomes of Lowry to the custom builds in Cherry Hills Village.
When HeatShield parts are backordered, we don’t leave you hanging. Our Haven buying network includes DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield, so we can quote alternatives with equivalent ratings and explain the trade-off in plain terms. Background-checked, uniformed technicians. License number on the page. A named tech assigned to your job. And if something isn’t right, the 365-Day Done Right Promise means we make it right.
FAQs
No, provided the work is performed to applicable codes and documented properly. HeatShield’s warranty covers manufacturing defects, not who opens the box. We document every repair with photos, part numbers, and installation details, which is what any warranty claim actually requires. If you’re unsure about your specific warranty terms, we can review them with you before we start. Call (720) 674-7312.
OEM HeatShield parts typically ship within five to ten business days to our Denver warehouse. During peak burning season (October through January), that can stretch to two or three weeks. We stock common burner assemblies, refractory panels, and draw bands from our multi-brand network to avoid leaving you without heat. We’ll tell you the real lead time before you commit, not after we’ve started.
Most HeatShield fireplace components can be repaired independently: liners, dampers, burners, and refractory panels are all serviceable items. We recommend replacement when the firebox structure is cracked through, the liner is perforated in multiple locations, or repair costs exceed sixty percent of a new insert. We show you the camera footage and the math, then you decide. No replacement is recommended without photo evidence you can see for yourself.
Gas HeatShield fireplaces: annually, per NFPA 211. Wood-burning HeatShield systems: after every cord of wood burned, or annually, whichever comes first. Denver’s altitude and dry climate accelerate burner oxidation and creosote buildup, so we see more frequent service needs than sea-level installations. We note condition trends in your documented record so you can plan ahead rather than react.
Gas units risk delayed ignition, sooting, and carbon monoxide venting issues. Wood-burning units accumulate creosote, which is combustible and the leading cause of chimney fires. In Denver’s tight, energy-efficient homes, even a small draft problem can pressurize CO into living space. The camera inspection reveals where you are in that progression. Call (720) 674-7312 for a free estimate and we’ll show you exactly what your system looks like today.
