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.

AfterHeatShield Chimney Cleaning & Sweep in Denver: What to Know First
We provide independent HeatShield chimney cleaning and sweep services across Denver, from Capitol Hill brick bungalows to the stucco ranches in Highlands Ranch. A standard HeatShield cleaning and Level 2 camera inspection runs $189-$349 depending on flue configuration and creosote class, with a written price delivered before any work starts. Most Denver HeatShield jobs book within 3-5 business days during sweep season, which runs September through March when Front Range temperature swings drive the heaviest fireplace use.
This page is for homeowners who know they’ve got a HeatShield liner, refractory system, or factory-built chimney component and need it swept, inspected, or diagnosed by a technician who understands how HeatShield products age in Denver’s high-altitude, freeze-thaw climate. Call (720) 674-7312 to speak with a live person and get a free written estimate.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam liner resurfacing separates from clay flue tiles in the smoke chamber. HeatShield’s Cerfractory Foam system is designed to smooth parged smoke chambers and resurface damaged clay liners, but in Denver’s dry climate with rapid temperature cycling, we’ve seen adhesion failure where the foam pulls away from spalling tile substrate. We camera-scan to confirm separation depth; if it’s surface-level, we re-prep and reapply under HeatShield-compatible protocols. If the clay substrate is too compromised, we quote a stainless liner from DuraFlex or Olympia Chimney with the written price in hand before any demolition.
- HeatShield UL-Listed relining develops longitudinal cracking in 6″-8″ round applications. The factory-applied refractory coating on HeatShield’s sleeved liner systems can develop hairline cracks after repeated thermal shock, especially in Denver homes that burn green lodgepole pine or construction scrap with high moisture content. Our Level 2 inspection catches these cracks before they propagate to the steel substrate. We document with photos, then either perform a warranty-safe local repair using HeatShield-compatible refractory mix or quote a full relining if the crack pattern exceeds 12 linear inches.
- Factory-built chimney chase covers pool water at the cricket. HeatShield’s chase cover geometry on certain 8/12 and 10/12 pitch chase assemblies doesn’t shed snow melt as aggressively as Denver’s spring freeze-thaw cycles demand. Water pools behind the cricket, accelerates galvanized steel corrosion, and drips into the flue. We replace with a Gelco or Famco stainless chase cover with improved cricket slope, or fabricate a copper alternative for historic Denver districts with design review requirements.
- Joint repair mortar degrades at flue tile connections above the roofline. HeatShield’s joint repair system depends on clean, accessible mortar beds between clay flue tiles. In Denver’s UV-intense environment, the top two joints often degrade faster than lower sections because of solar heating combined with flue gas cooling. We find this with our camera scan, remove the degraded material, and reapply using HeatShield-specified refractory mortar or, if access is limited, transition to a flexible liner system that eliminates the joint entirely.
- Smoke chamber parging flakes into the firebox during sweep. When we run brushes through a HeatShield-parged smoke chamber with existing adhesion issues, refractory material can delaminate and fall. We don’t just sweep and hope. We pre-scan, identify parging condition, and if flaking is present, we stop the sweep, show the homeowner the camera footage, and quote smoke chamber repair before continuing. The camera doesn’t guess. Neither do we.
Our HeatShield Chimney Cleaning & Sweep Process
- 1
Call intake with HeatShield-specific triage. Our live answer team asks for the model line if you know it, the installation year, and your burn habits. This lets us flag likely issues before the truck rolls.
- 2
NFPA 211 Level 2 inspection with camera scan. Corrine Halstead trained her crew to run the camera first, sweep second. We document flue condition, liner integrity, and creosote class with time-stamped photos under Haven Standard Clause 4.
- 3
Written price and scope delivered on-site. Before any brush touches flue, you get a printed price, printed scope, and printed warranty terms. Haven Standard Clause 1: have it in writing.
- 4
HeatShield-compatible cleaning and repair. We select brushes and rods rated for refractory surfaces, use OEM-specified refractory materials where repair is needed, or quote quality aftermarket alternatives from our Haven buying network when HeatShield parts are backordered.
- 5
Post-work camera verification and photo record. We re-run the camera to confirm clean flue, intact repairs, and proper draft. Your documented record is emailed before we leave.
- 6
365-Day Done Right Promise activation. If anything in the scope isn’t right, we make it right. Stamped on every job.

Why Denver Homeowners Call Level Two Chimney Denver for HeatShield Work
We’ve swept and inspected more than 38,000 chimneys since 2009, and a significant share in Denver have been HeatShield systems installed during the 2012-2019 relining boom. Our technicians know the difference between a HeatShield UL-Listed sleeve and a competitor’s refractory coating, and they know which Denver neighborhoods, like the 1890s Victorians along Federal Boulevard, present access challenges that change the scope.
Our Haven Standard buying network sources materials from DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield, so if HeatShield parts are delayed, we can quote equivalent-quality alternatives without leaving you in queue. Every tech is background-checked, uniformed, and assigned by name; you get a text when they’re en route. And our 24/7 live phone support means you’re never leaving a voicemail during a Denver cold snap when you smell smoke where you shouldn’t.
FAQs
No, provided we use HeatShield-compatible materials and documented procedures. As an independent HeatShield service provider, we are not affiliated with or authorized by HeatShield, but warranty coverage depends on proper installation and compatible repair materials, not brand authorization alone. We document every step with photos to protect your coverage. Call (720) 674-7312 for a free estimate.
You don’t, and neither do we, until the camera goes down. A Level 2 inspection reveals whether surface staining is active deterioration or cosmetic residue. We show you the footage and explain what we’re seeing before quoting any repair. Call (720) 674-7312 to book.
Certain refractory mixes and factory chase components can run 2-3 weeks from HeatShield’s distribution network, especially in peak season. Because we maintain relationships with DuraFlex, Gelco, and Olympia Chimney through our Haven buying network, we can often source equivalent-specification alternatives faster, with the same written warranty. Call (720) 674-7312 to check current availability for your model.
NFPA 211 recommends annual inspection; sweep frequency depends on use and fuel. Denver’s high altitude increases draft variance, and our dry winters produce more airborne ash that settles in flue bends. Most HeatShield systems we service in the metro area benefit from annual sweep if burned more than 30 evenings per season. Call (720) 674-7312 to set a schedule that matches your burn habits.
Class III creosote hardens into a fuel source that burns at 2,000°F, and HeatShield’s refractory coating, while rated for high temperature, is not designed to contain a chimney fire. Carbon monoxide can also leak through degraded smoke chamber parging or liner cracks before you smell any problem. The camera finds these issues early; skipping the inspection means finding them during an emergency. Call (720) 674-7312 for a free estimate.
Ready to get your HeatShield system inspected, swept, and documented? Call (720) 674-7312 to speak with a live person now. We’ll schedule your Level 2 camera inspection, deliver a written price before any work starts, and leave you with a photo record you can reference for years.
