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.

AfterWhy Dallas Homeowners Choose HeatShield Chimney Cleaning
Level Two Chimney Dallas provides independent Dallas Heatshield service including chimney cleaning, repair, and resurfacing across Dallas and surrounding areas. We’re not affiliated with or authorized by HeatShield - we’re experienced local technicians who’ve installed and serviced HeatShield masonry resurfacing systems in hundreds of North Texas homes since 2009. Our HeatShield work is backed by Clause 4 of the Haven Standard: a camera-scan inspection and documented photo record on every visit, plus a written price before any work starts.
HeatShield is a refractory mortar coating system designed to restore cracked, spalled, or deteriorated firebox brick and smoke chamber walls without full rebuilds. In Dallas, where Blue Northers send homeowners scrambling to light fireplaces that sat idle for 10-11 months, we’ve seen HeatShield perform well when properly applied - and fail prematurely when surface prep is skipped or underlying moisture problems are ignored. Our crew works throughout Lake Highlands, Lakewood, Oak Cliff, and across the metro, including the older masonry stock in the M Streets where 1920s-1950s fireboxes are prime candidates for Mesquite Heatshield service and restoration.
Camera goes in first. Everything else follows.
Why Trust Level Two Chimney Dallas for Your HeatShield Chimney Cleaning?
Corrine Halstead, our owner, learned the trade at Apex Technical School in Long Island City before relocating to Texas - she figured the state had more chimneys than she could count, and she wasn’t wrong. She’s been working Dallas-area fireplaces for years, including regular jobs in Lake Highlands where older homes still burn hard through short winters. Her approach is straightforward: walk the customer through exactly what the camera found before recommending anything. No upsells without photographic evidence. No vague estimates.
Our technicians are background-checked, uniformed, and assigned by name. You’ll get a text when your tech is en route, and their license information is displayed on every page. We’ve completed more than 38,000 chimney inspections and our Chimney Cleaning & Sweep services since 2009, every one with a written price before work started and a documented record when finished.
For HeatShield specifically, we stock genuine HeatShield refractory mortar and additives for repairs, ensuring compatibility with existing coatings. We also source quality aftermarket stainless caps, dampers, and flashing through our Haven buying network when OEM equivalents are unavailable. We know the difference between HeatShield Standard and HeatShield Plus, understand the cure requirements for each, and won’t apply either over active moisture intrusion or unsound substrate - because we’ve seen what happens when someone does.
Our 365-Day Done Right Promise applies to every HeatShield job: if it’s not done right, we make it right. And our Free Second Opinion on any written estimate means you can bring us a competitor’s HeatShield quote and we’ll tell you straight whether the scope matches what your chimney actually needs.
Common HeatShield Chimney Cleaning Problems We Fix in Dallas
- Delamination and flaking in the firebox. HeatShield Standard or Plus applied over soot or creosote without proper surface prep will delaminate, sometimes within a single season. The coating separates from the brick in sheets, exposing the substrate underneath. We see this most often in Dallas homes where a previous sweep or handyman skipped the grinding and bonding slurry steps. Our fix: remove the failing material entirely, grind back to sound brick, apply a proper bonding slurry, then re-coat with HeatShield Plus for better adhesion.
- Cracking at the smoke chamber transition. Dallas’s extreme thermal cycling - 105°F summer baking followed by sudden Blue Norther drops of 30-40°F - causes masonry substrate movement that cracks HeatShield at the smoke chamber throat. This isn’t a HeatShield product failure; it’s a substrate movement problem. We address it by evaluating whether the smoke chamber needs parging before coating, and we always check for foundation-related chimney shifting that will crack any surface treatment.
- Premature wear around the damper frame and lintel. HeatShield applied near the damper often shows erosion or discoloration when moisture intrusion from a cracked crown or failed flashing goes unaddressed. The water wicks behind the coating, undermining it from the back. We won’t apply fresh HeatShield without first repairing the crown or flashing source - Clause 1 of the Haven Standard requires a written scope that includes everything needed for a lasting repair, not just the visible symptom.
- HeatShield Crown Coat breakdown on exterior crowns. HeatShield Crown Coat is a flexible repair coating for chimney crowns, but it won’t save a crown with active spalling, no expansion joints, or structural cracks from Blackland Prairie clay soil movement. We’ve found Crown Coat applied over crumbling concrete in Dallas homes, where it simply cracks and discolors within a year. Our honest assessment: crown repair or full rebuild first, then Crown Coat as a protective layer if the substrate is sound.
- Failed insert surround resurfacing. The HeatShield Fireplace Insert Resurfacing Kit is designed for cast-iron or steel insert surrounds, but it requires the same clean, dry substrate as any HeatShield application. In Dallas’s humid summers, we’ve seen inserts removed and surrounds coated while moisture was still trapped in the masonry, leading to bubbling and poor adhesion. We verify substrate dryness with moisture readings before application - part of our standard camera-and-documentation process.

AfterHeatShield Parts & Our Repair-vs-Replace Approach
We use genuine HeatShield refractory mortar and additives for repairs to ensure chemical and thermal compatibility with existing coatings. Our local inventory includes HeatShield Standard, HeatShield Plus with fiber reinforcement, bonding slurry, and Crown Coat - procured through our Haven buying network to keep customer prices honest. For associated components like stainless caps, dampers, and flashing, we source quality aftermarket parts from DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield when HeatShield OEM equivalents aren’t available.
Here’s our honest line: HeatShield is a restorative coating, not a structural fix. If a flue or firebox has structural cracks, spalling beyond 1/4-inch depth, or loose brick, we recommend a full rebuild rather than a cosmetic patch. We’ll show you the camera footage and explain exactly where the coating ends and structural repair begins. No guesswork. No surprises when the written price arrives.

Our HeatShield Service Process - Step by Step
- 1
Camera-scan diagnosis. We run an NFPA 211 Level 2 inspection with a camera down the flue and through the firebox. For HeatShield evaluations, we’re looking specifically for delamination patterns, substrate moisture, crown and flashing condition, and whether previous coating was applied over creosote or sound brick. You get photos and footage of everything we find.
- 2
Written scope and price. Before any work begins, we deliver a written price, written scope, and written warranty - Haven Standard Clause 1, H.A.V.E.N. “Have it in writing.” For HeatShield jobs, this includes surface prep requirements, material specification (Standard vs. Plus vs. Crown Coat), and any necessary crown or flashing repair that must precede coating.
- 3
Surface prep and repair. We grind failed coating to sound brick, apply bonding slurry where required, and address moisture sources. In Dallas’s climate, this step is non-negotiable - humidity and heat affect cure times, and we schedule application when conditions allow proper set.
- 4
HeatShield application and cure. We apply the specified HeatShield product per manufacturer cure requirements, accounting for local temperature and humidity. HeatShield Standard typically requires 24-48 hours before light firing; HeatShield Plus with fiber reinforcement may need longer. We provide specific written guidance for your application.
- 5
Post-application test and documentation. We verify damper operation, draft performance, and visual integrity of the completed coating. Clause 4 of the Haven Standard requires a documented photo record on every job - you’ll receive this archive, including before-and-after images, as standard.

FAQs - HeatShield Chimney Cleaning Service in Dallas
No. We are an independent HeatShield service provider, not affiliated with or authorized by the manufacturer. Our expertise comes from years of installing and servicing HeatShield products in Dallas-area homes, not from factory certification. We use genuine HeatShield materials for repairs and stand behind our work with the 365-Day Done Right Promise.
Yes, for the refractory mortar and additives that must chemically match existing coatings. For associated hardware like caps, dampers, and flashing, we use quality aftermarket parts from DuraFlex, Gelco, and other suppliers when HeatShield OEM equivalents are unavailable. We disclose exactly what we’re using in your written scope before work begins.
Most firebox resurfacing jobs require one full day for surface prep, application, and initial cure. Smoke chamber work adds time for access and inspection. Crown Coat application is faster - typically a half-day - but only after any underlying crown repair is complete. We provide a specific timeline in your written estimate. Call (972) 284-1392 to schedule.
We service and install HeatShield Standard, HeatShield Plus, HeatShield Fireplace Insert Resurfacing Kit, and HeatShield Crown Coat. We do not work with HeatShield on prefabricated zero-clearance metal fireboxes - the product is designed for masonry restoration, and applying it to metal substrates will fail.
HeatShield’s warranty terms apply to original installations by authorized contractors; as an independent provider, our repairs do not carry the manufacturer’s warranty. We provide our own 365-Day Done Right Promise on all HeatShield work, and we document every job with photos and written scope so you have a clear record of what was done and why.
HeatShield firebox or smoke chamber resurfacing in Dallas typically runs $1,800-$3,400 depending on surface area, prep requirements, and whether crown or flashing repair is needed. HeatShield Crown Coat application on a sound crown is usually $600-$1,200. We deliver a written, itemized price before any work starts - no exceptions. Call (972) 284-1392 for an exact quote; estimates are free.
No, not without removing the failed material first. Cracking or flaking indicates delamination, moisture intrusion, or application over unsound substrate. We grind off the failing coating, evaluate the brick underneath, and start fresh with proper prep. Applying new HeatShield over delaminated old HeatShield guarantees the same failure.
Dallas’s long hot summers and high humidity slow cure times and can trap moisture in improperly prepped substrates. We schedule HeatShield application during appropriate weather windows and verify substrate dryness with readings. The bigger long-term threat is thermal cycling - 105°F summers to hard freezes - which cracks masonry and any coating applied without addressing movement.
No. HeatShield is formulated for masonry fireboxes, smoke chambers, and crowns. Prefabricated zero-clearance fireplaces have metal fireboxes and specific UL-listed clearances; applying refractory mortar to metal surfaces will crack and potentially create a fire hazard. We evaluate your fireplace type during camera inspection and recommend appropriate repair paths.
Standard mortar (Type N or S Portland cement mix) is not rated for firebox temperatures and will crumble under heat. HeatShield is a refractory mortar formulated to withstand direct flame exposure and thermal shock. For cosmetic cracks in non-firebox areas, standard mortar may suffice; for firebox walls, smoke chambers, and lintel areas, HeatShield or equivalent refractory material is required for safety and durability.
HeatShield Standard typically requires 24-48 hours of cure before a small, controlled fire to complete the curing process. HeatShield Plus may need 48-72 hours depending on application thickness and ambient conditions. We provide specific written instructions for your job, including the recommended first-fire protocol to properly cure the coating without thermal shock.
