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.

How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam liner resurfacing cracks or delaminates. In Littleton’s freeze-thaw cycles, the foam layer can separate from the original clay flue tile, especially where the chimney crown has hairline fractures that let water migrate behind the coating. We camera-scan to map the delamination, then remove the failed foam section-by-section and reapply to bare tile, or recommend a stainless liner if the substrate is too compromised.
- HeatShield Joint Repair fails at the mortar joints between flue tiles. The product seals smoke chamber and flue joints, but in older Littleton homes with shifting foundations common to the Front Range clay soils, new gaps can open adjacent to the original repair. We don’t just patch the patch - we inspect the full smoke chamber with a chimney camera to find the movement pattern, then reapply Joint Repair or transition to a full Cerfractory Foam coat if the joint pattern is too extensive.
- Smoke chamber parging degrades faster than expected. HeatShield’s smoke chamber sealant is rated for high heat, but heavy wood-burning use in Littleton’s long heating season (October through April, often longer) can glaze the surface with Class III creosote, a hard, tar-like deposit that traps acidic moisture. We remove the creosote mechanically, assess the parging integrity with a camera, and re-parge only where the original coating has eroded to bare brick.
- Fireplace insert installations develop draft issues. HeatShield inserts, particularly the wood-burning models popular in 2015-2020 Littleton remodels, can pull poorly if the chimney is exterior and cold. We measure draft pressure with a manometer, check the liner sizing against the insert’s BTU output, and correct with an insulated flex liner from our DuraFlex inventory if the original HeatShield liner is undersized or uninsulated.
- Gas fireplace components outlast the ignition system. The HeatShield firebox and log set may be sound, but the pilot assembly or valve train fails. We stock common HeatShield-compatible valves and ignition modules through our Haven buying network, and when OEM parts are back-ordered, we source quality aftermarket equivalents that don’t void the equipment warranty - with the trade-off documented in writing before installation.
Our HeatShield Fireplace Services Process

- 1
Call and schedule. A live person answers, checks Corrine’s crew availability in Littleton, and books a window. You get a text when your tech is en route.
- 2
Camera-scan inspection. We run a chimney camera the full length of the flue per NFPA 211 Level 2 standard. The camera doesn’t have an opinion - it just shows you what’s there. You see the footage on a tablet before any quote is written.
- 3
Written diagnosis and price. We name what we found (delaminated Cerfractory Foam, failed joint, Class III creosote buildup, etc.), specify OEM or aftermarket parts, and deliver a written price, scope, and warranty before work starts. Haven Standard Clause 1: have it in writing.
- 4
Repair with documented steps. The tech performs the work, photographing each stage. Corrine’s crew has handled HeatShield systems throughout Littleton, including the masonry fireplaces in older Columbine Knolls homes where the original clay tile flues require careful prep before any foam application.
- 5
Post-repair test and photo record. We run a combustion analysis or draft test, then provide a documented photo record of the completed work. Haven Standard Clause 4 requires this archive - we’ve done it on every job since 2009.
- 6
365-Day Done Right Promise. If the repair doesn’t hold, we make it right. The warranty is stamped, dated, and in your hand before we leave.

Why Littleton Homeowners Call Level Two Chimney Littleton for HeatShield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those have been in Littleton and the surrounding Denver metro area. Corrine Halstead’s crew knows the local failure patterns: the way Front Range temperature swings stress HeatShield foam, the creosote buildup from piñon pine and cottonwood common in Littleton firewood stacks, the foundation movement that reopens sealed joints.
We’re an independent HeatShield service provider - not affiliated with or authorized by the manufacturer - which means we source parts through our Haven buying network from HeatShield, DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield to keep pricing honest and options open. Every tech is background-checked and uniformed, with a license number you can verify. The 365-Day Done Right Promise applies to every repair, and our Free Second Opinion policy means you can bring us any competitor’s written estimate for comparison.
FAQs
No. As an independent HeatShield service provider, we follow manufacturer installation and repair specifications, and we document our work with photos and written scope. If a warranty claim arises, you have the paperwork. For warranty questions specific to your product line, call us at (720) 439-4666 and we’ll review your documentation.
Cerfractory Foam and Joint Repair typically last 15-20 years when the chimney crown and cap are intact, but Littleton’s freeze-thaw cycles and occasional hail can accelerate crown cracking. We inspect the crown as part of every HeatShield job and quote crown repair separately if water intrusion would undermine the repair. Call (720) 439-4666 for a free estimate - estimates are free.
We source both. For Cerfractory Foam and Joint Repair, we use OEM materials. For gas fireplace valves, igniters, and some refractory panels, OEM backorders can run 4-6 weeks, so we stock quality aftermarket equivalents through our Haven network. We document which we’re using and why, in writing, before installation. Call (720) 439-4666 for availability on your specific model.
Not necessarily. Poor draft in a HeatShield system often traces to an undersized or uninsulated flex liner, a blocked cap, or negative pressure in a tightly sealed modern home. We measure draft with a manometer and camera-scan the flue before recommending any replacement. Many draft issues resolve with cleaning, cap repair, or liner insulation - all quoted in writing first. Call (720) 439-4666 for a free estimate - estimates are free.
NFPA 211 recommends annual inspection for all fireplace systems, including HeatShield. In Littleton, where heating season runs six to seven months and wood-burning use is heavy in older neighborhoods like Columbine Knolls, we find that annual camera inspection catches creosote buildup and foam degradation before they become safety hazards. We don’t upsell - we show you the camera footage and quote only what the evidence supports. Call (720) 439-4666 to schedule.
