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 Evanston Homeowners Choose HeatShield Chimney Cleaning
Level Two Chimney Evanston provides Heatshield repair in Evanston, including independent HeatShield chimney cleaning, repair, and relining service for homes across Evanston, IL, with ceramic flue sealant and stainless liner work backed by written pricing and camera documentation on every visit. We’re not affiliated with or authorized by HeatShield - we’re an independent service provider that has installed and serviced their systems for over a decade, and we know how they hold up in real Chicago-area conditions. Call (708) 234-1174 for a free estimate.
Evanston’s dense concentration of 1880s-1920s multi-flue masonry chimneys faces unusually aggressive deterioration from Lake Michigan’s northeast moisture-laden winds and 30-40 annual freeze-thaw cycles. This combination of century-old construction and direct lake exposure makes annual chimney inspection a genuine structural necessity in Evanston, not a routine upsell. The unlined or deteriorated-liner chimneys prevalent throughout east-side historic neighborhoods require careful evaluation before any wood-burning use, and HeatShield’s ceramic and stainless systems are among the options we regularly assess, install, and maintain.
Corrine Halstead, our owner, grew up in Queens and learned the trade at Apex Technical School in Manhattan before bringing her focus to the Chicago area. She and our crew have been running inspections and cleanings across Evanston for several years now, including jobs on the older masonry stacks near the Evanston lakefront historic district. The camera doesn’t negotiate - and neither does creosote.
Why Trust Level Two Chimney Evanston for Your HeatShield Chimney Cleaning?
We know HeatShield products from hands-on relining work, not from a manufacturer’s training manual. Our technicians have installed HeatShield Cerfractos ceramic sealant systems in offset clay tile flues, pulled and replaced HeatShield stainless liners where condensate damage had set in, and diagnosed insulation blanket failures that other sweeps missed because they didn’t run a camera the full length of the flue.
Our approach to HeatShield service follows the same protocol we apply to every brand we work with: NFPA 211 Level 2 inspection with camera-scan documentation, written price before any work starts, and a documented photo record on completion under Haven Standard Clause 4. We’ve maintained that practice since 2009, and it applies whether we’re touching up a Cerfractos coating or replacing a full stainless liner system.
We source HeatShield OEM components through Haven’s buying network when they’re available, and we only substitute equivalent UL-listed aftermarket parts when the OEM item is backordered or discontinued. We don’t guess at compatibility - we check part numbers against the installed system and document what goes in. If a flue can be saved with targeted repair rather than full relining, we’ll recommend that. When the clay tiles are spalling or the liner is perforated, replacement is the only safe option, and we’ll show you the camera footage that proves it before we quote the work.
Corrine’s known for showing customers the camera footage first and the invoice second. Nothing gets approved without both on the table.
Common HeatShield Chimney Cleaning Problems We Fix in Evanston
- Cerfractos sealant cracking or delaminating at flue tile joints. This happens when the original clay tiles weren’t properly cleaned or primed before the ceramic coating went on. In Evanston’s older masonry chimneys with offset flues - common in Victorian and Craftsman homes east of Ridge Avenue - the uneven tile surfaces and tight bends make thorough surface prep difficult. Moisture from Lake Michigan’s persistent northeast winds penetrates the compromised sealant, and freeze-thaw cycles widen the cracks within a season or two. We see this on relines that were done quickly, without the acid-wash and drying time the Cerfractos system requires.
- Stainless liner corrosion at top and bottom terminations. High-efficiency gas appliances produce condensate that pools where the liner meets the appliance adapter or the rain cap. The alloy pits, thins, and eventually allows flue gas leaks into the chimney cavity. Evanston’s exterior chimneys are especially vulnerable because the metal experiences wider temperature swings than interior flues. We inspect these terminations with a camera and a flashlight, measure wall thickness where we can, and replace the damaged section with matching HeatShield stainless or equivalent UL-listed material.
- Insulation blanket shifting or settling inside the liner. During installation, the blanket must be held in compression until the liner is fully seated. If it shifts, hot spots develop that warp the inner liner and void the UL listing. We’ve found this on jobs where the original installer didn’t use the specified spacers or rushed the pour on a poured-insulation job. The fix is partial or full liner replacement, depending on how much the inner wall has distorted.
- Liner-to-appliance connector failure after freeze-thaw cycles. Loose screws, missing adapters, or corroded fasteners let the liner pull away from the appliance collar. Combustion gases spill into the basement or living space. We see this frequently on Evanston homes with exterior chimneys, where the thermal expansion and contraction is most extreme. Our repair includes proper fastening with high-temperature hardware and a smoke test to confirm seal integrity.
- Forgotten secondary flues interfering with active HeatShield liners. In Evanston’s larger Victorian and Craftsman homes, sweeps routinely discover secondary flues that once served coal furnaces, sometimes opening into wall cavities or unlined attic spaces alongside still-active fireplace flues. Homeowners frequently have no idea these flues exist. A HeatShield liner installed in the active flue can be compromised if the abandoned flue is collapsing or leaking moisture into the shared masonry. Full camera inspection of all flues is standard for us, not optional, and we’ve caught problems that a single-flue inspection would have missed.

AfterHeatShield Parts & Our Repair-vs-Replace Approach
We stock HeatShield Cerfractos compound, stainless liner sections in common diameters, and termination hardware locally for fast turnaround on Evanston jobs. When we open a chimney and find a HeatShield system that needs attention, our first question is whether the existing components can be restored to safe function or whether they’ve reached end of useful life.
A homeowner on the 1200 block of Asbury called us after a chimney fire scare - their HeatShield Cerfractos reline from six years earlier was still intact, but the top two flue tiles above it had spalled and were blocking the liner. We rebuilt the crown, installed a new stainless multi-flue cap, and re-coated the exposed tile with HeatShield Cerfractos to match the original system, restoring proper draft without a full tear-out. That’s a repair. When we find a perforated stainless liner or spalling clay tiles throughout the flue, that’s replacement, and we’ll show you the footage that makes the case.
We use OEM HeatShield Cerfractos and stainless components when available. If the OEM item is backordered or discontinued, we switch to equivalent UL-listed aftermarket parts and document the substitution in your job record. Every recommendation comes with camera evidence you can see for yourself. Call (708) 234-1174 for an exact quote - estimates are free.
Our HeatShield Service Process - Step by Step
- 1
Diagnosis with NFPA 211 Level 2 inspection. We run a camera the full length of the flue, document the HeatShield system condition, and check for the Evanston-specific issues: lakefront moisture intrusion, freeze-thaw damage to exterior chimneys, and abandoned secondary flues. You get the footage and a written condition report before we quote any work.
- 2
Written price and scope before work starts. Haven Standard Clause 1 requires it: written price, written scope, written warranty. No exceptions. You’ll know exactly what HeatShield parts we’re using, whether they’re OEM or equivalent aftermarket, and what the finished job includes.
- 3
Repair or install with documented procedures. For Cerfractos work, we follow the manufacturer’s surface-prep protocol - acid wash, drying time, application in specified lifts - because shortcuts cause the delamination we see too often. For stainless liner work, we verify insulation placement, secure all terminations with proper hardware, and confirm appliance connection integrity.
- 4
Testing and verification. Smoke test, draft measurement, and final camera run to confirm the repair or installation meets code and performs as specified. We don’t clear a chimney for use until the numbers are right.
- 5
Warranty documentation and photo record. Haven Standard Clause 4 requires a documented photo record on every job. You get the photos, the test results, and the 365-Day Done Right Promise in writing before we leave.
HeatShield Products We Service & Install in Evanston
We work with HeatShield Cerfractos ceramic flue sealant for clay tile flues, HeatShield stainless steel liner systems for wood and gas appliances, and HeatShield insulated chimney liners in both poured and wrap insulation versions. We stock Cerfractos compound, liner sections in 5.5-inch through 8-inch diameters, and common termination caps and adapters for Evanston’s typical residential flue sizes. For less common diameters or discontinued HeatShield components, we source equivalent UL-listed alternatives through Haven’s buying network and confirm compatibility before installation.
We also perform chimney rebuilding, flashing repair, and crown coating - services that often accompany our Chimney Cleaning & Sweep services and HeatShield liner work in Evanston’s weather-beaten masonry.
We Also Service These Brands
Level Two Chimney Evanston is not a single-brand shop. We install and service DuraFlex stainless liners and Gelco chimney caps and accessories with the same camera-documented, written-price protocol we apply to HeatShield work. Our multi-brand capability means we recommend the right product for your chimney’s condition and your appliance type, not the only product we know how to sell.
FAQs - HeatShield Chimney Cleaning Service in Evanston
No. We are an independent HeatShield service provider, not affiliated with or authorized by the manufacturer. Our expertise comes from hands-on installation and repair work on HeatShield systems in Chicago-area homes since 2009, not from factory training or dealer status. We source OEM and equivalent UL-listed parts through independent supply channels and document everything we install.
Yes, when they’re available. We use OEM HeatShield Cerfractos and stainless components as our first choice. If the OEM item is backordered or discontinued, we use equivalent UL-listed aftermarket parts and document the substitution in your job record. You see the part numbers and the compatibility verification before work starts.
Most HeatShield repairs and maintenance cleanings take two to four hours on site. A full Cerfractos reline or stainless liner replacement typically requires a full day, plus curing time for sealants before the chimney can be used. We give you a written schedule with your written price, and we don’t start until you’ve approved both.
We service and install HeatShield Cerfractos ceramic flue sealant systems, HeatShield stainless steel liners for wood and gas, and HeatShield insulated liners in both poured and wrap insulation versions. If you have a specific model or installation date, we can verify compatibility when you call.
Manufacturer warranties typically require installation by a qualified professional following specified procedures. As an independent provider, we follow HeatShield’s published installation and repair protocols and document our work with photos and test results. We cannot guarantee warranty coverage - only the manufacturer can do that - but we can provide the documentation you would need to file a claim. If warranty preservation is critical to you, we recommend contacting HeatShield directly before scheduling service.
HeatShield chimney cleaning and inspection in Evanston typically runs $280-$420 for a standard NFPA 211 Level 2 service with camera documentation. Cerfractos touch-up repairs start around $450-$780 depending on flue length and access. Full stainless liner replacement ranges from $2,800-$4,500 for most Evanston single-flue residential chimneys, with multi-flue or complex installations higher. We deliver a written, itemized price before any work starts - never a ballpark that changes on site. Call (708) 234-1174 for an exact quote - estimates are free.
Schedule an NFPA 211 Level 2 inspection with camera documentation. At five years, a properly installed Cerfractos system in an interior chimney with good draft should still be sound. In Evanston’s exterior chimneys exposed to lakefront winds and freeze-thaw cycles, we sometimes see earlier deterioration at the flue tile joints or crown interface. The camera shows whether the sealant is intact, cracked, or delaminating - and whether the underlying clay tiles have begun to spall. Repair is possible if the damage is localized. Replacement is necessary if the tile substrate is failing throughout. We show you the footage and quote both options when both exist.
HeatShield manufactures stainless steel liner systems rated for both wood-burning and gas appliances, though the alloy specification and sizing differ. Gas appliances produce more acidic condensate and require proper liner sizing to the appliance’s BTU output and vent configuration. We’ve replaced undersized HeatShield gas liners that were corroding prematurely because the original installer matched the liner to the flue dimensions rather than the appliance’s venting requirements. The correct approach is appliance-first sizing, then flue verification.
Three common causes: improper surface preparation before Cerfractos application, leading to early delamination; condensate pooling at a gas appliance connection due to incorrect liner sizing or missing drain fitting; or insulation blanket shifting during installation, creating hot spots that warp the liner. Evanston’s exterior chimneys add a fourth factor: more severe freeze-thaw stress than interior flues experience. We diagnose the specific cause with camera footage and written documentation, then quote the fix that addresses the root problem, not just the symptom.
Yes, provided the cap is properly sized to the liner termination and allows adequate draft for the appliance. We verify compatibility between the cap model and the liner diameter, and we confirm that the cap’s spark arrestor mesh (if required) matches local code. In Evanston, we often pair multi-flue stainless caps with HeatShield liners on homes with multiple active flues, sealing abandoned flues separately to prevent moisture intrusion.
HeatShield and DuraFlex both manufacture UL-listed stainless steel chimney liners, but their product lines differ in alloy options, insulation methods, and fitting systems. HeatShield’s Cerfractos ceramic sealant is unique to their brand and suited to clay tile flues with intact structure but compromised mortar joints. DuraFlex offers different alloy grades and a distinct connector system. The better choice depends on your chimney’s condition, your appliance type, and your budget. We stock both brands and recommend based on what we find during inspection, not on which product we prefer to sell. You’ll see the camera footage and the written comparison before deciding.
