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 Bellevue Homeowners Choose HeatShield Chimney Cleaning
We provide independent HeatShield service in Bellevue, WA, including chimney cleaning, repair, and restoration, including full Level 2 camera inspection, firebox repair, and crown coating for homes with HeatShield-treated flues. Our technicians have restored hundreds of clay-tile flues with HeatShield across King County, and we document every joint, every spalled tile, and every recommendation with photos before we quote a dollar. Call (425) 696-0387 for a written estimate.
HeatShield is a chimney liner restoration system, not a cleaning product. The ceramic joint compound, the foam-and-mandrel resurfacing process, and the CeCure structural sleeve are tools we use when the clay tile is sound but the mortar joints have opened or the surface has degraded. In Bellevue, where 1960s tract homes in Lake Hills and Crossroads still run original single-wythe brick chimneys, we see a lot of HeatShield work that was done too late, too fast, or over tile that was already structurally gone. We’re not affiliated with or authorized by HeatShield. We’re an independent service provider that knows when the product works, when it doesn’t, and when a flue needs to be relined or rebuilt instead.
Why Trust Level Two Chimney Bellevue for Your HeatShield Chimney Cleaning?
Corrine Halstead, our owner, learned this trade at Apex Technical School in Manhattan before bringing her work out to the Pacific Northwest. She and our crew have been servicing Bellevue and Sammamish properties for several years now, including older wood-burning fireplaces in the Lakemont neighborhood where the homes see real use through the wet season. Corrine is known for pulling the camera footage and walking customers through exactly what it shows. The camera doesn’t guess. Neither do I.
That approach matters with HeatShield because the product’s success depends entirely on what happens before the compound goes in. We use genuine HeatShield ceramic joint repair compound and CeCure components because the formulation and cure schedule are the system. We don’t substitute generic refractory cement and call it the same thing. Our technicians are background-checked, uniformed, and carry license information on every page of every job folder. Clause 4 of the Haven Standard requires a documented photo record on every visit, and that includes the pre-application flue condition, the open joints we found, and the finished repair. We’ve maintained that archive practice since 2009.
We also won’t sell you a HeatShield repair over a flue that needs relining or rebuilding. For Bellevue’s older masonry chimneys, that honesty often means the HeatShield job is the smaller half of the work. We’d rather quote the correct fix than quote a cheap one and have you call us back when the coating fails.
Common HeatShield Chimney Cleaning Problems We Fix in Bellevue
- Ceramic joint compound flaking out of mortar joints. This happens when the flue was not properly cleaned or primed before application, or when the original clay tile was actively spalling underneath. In Bellevue’s 1960s-70s chimneys, we find this constantly. The prior company swept the flue, maybe, but didn’t camera-scan to confirm the tile surface was sound. The compound adheres to dust and loose tile instead of solid clay, and six months later it’s coming out in chunks. We chip it all out, re-prime properly, and re-apply HeatShield CJR only where the substrate is viable.
- Resurfacing material cracking or delaminating after a chimney fire or repeated overfire conditions. HeatShield Resurfacing System is rated for normal operating temperatures, but a chimney fire or habitual overfiring changes the thermal expansion profile of the underlying clay tile. The coating can’t flex where the tile won’t, so it cracks. We see this in Bellevue homes where the homeowner burned unseasoned fir through a wet winter and didn’t realize the flue had already seen 2100°F. Our Level 2 inspection catches the thermal damage before we quote any resurfacing.
- CeCure sleeve liners developing gaps at the top termination or bottom transition. The CeCure sleeve is a structural repair for badly damaged flues, but it’s only as good as the cap and crown that protect it. We find sleeves with three-inch gaps at the top because the original crown was cracked and nobody fixed it, or because the cap was the wrong size and water ran straight down the annular space. In Bellevue, where 37 inches of annual rain concentrate October through April, that’s a predictable failure. We coat or rebuild the crown and reset the cap as part of the sleeve installation, not as an upsell.
- HeatShield repairs applied over actively spalling or crumbling clay tile. This is the most expensive mistake we correct. Spalling is when freeze-thaw cycling pops the face off the clay tile, leaving a porous, crumbling substrate. Coating over it is like painting over wet drywall. The tile continues to fail beneath the coating, and the homeowner gets another smoky fireplace in two years. Our camera inspection identifies spalling tile by tile. If the structural integrity is gone, we quote relining or rebuilding, not HeatShield.
- Poor draft and smoke staining after a prior HeatShield job. A Bellevue homeowner in the Lake Hills area called us because smoke was staining the mantel on a 1960s brick fireplace, and our Level 2 inspection found several HeatShield ceramic joint repairs from a prior company already flaking out of the flue. We swept the flue, chipped out the failing compound, re-primed the clay tile, and re-applied HeatShield CJR to the open joints, then coated the cracked crown and reset the cap. The smoke staining stopped because the joints were actually sealed this time, and we noted the two spalling tiles at the top of the stack for monitoring rather than coating over them.

AfterHeatShield Parts & Our Repair-vs-Replace Approach
We stock genuine HeatShield ceramic joint repair compound, CeCure sleeve components, and HeatShield 2000 high-temperature joint repair for wood-burning appliances. These come through our Haven buying network, which sources from HeatShield, DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield specifically to keep customer prices honest. We don’t use aftermarket refractory cement as a substitute for the formulated compound. The cure schedule, the thermal expansion coefficient, and the bond strength are the product.
That said, we will not sell a HeatShield repair over a flue that needs relining or rebuilding. If the tile is structurally shot, we tell you and quote the correct fix. For Bellevue’s older masonry chimneys, that honesty often means the HeatShield job is the smaller half of the work. We document the spalling, the cracked tiles, the compromised mortar joints with photos, and we write the price for each option before any work starts. Clause 1 of the Haven Standard: have it in writing. Call (425) 696-0387 for a written estimate.
Our HeatShield Service Process - Step by Step
- 1
Diagnosis: NFPA 211 Level 2 camera inspection. We run a camera the full length of the flue and document every joint, every tile face, every area of spalling or delamination. For HeatShield candidates, we’re looking specifically for open mortar joints, surface degradation, and sound structural tile. If the tile is crumbling, we stop here and quote relining.
- 2
Preparation and repair scope. We chip out any failing prior compound, clean the flue to bare tile, and apply HeatShield primer where the substrate is viable. We write the scope, the price, and the warranty before any application begins. Clause 1 of the Haven Standard.
- 3
HeatShield application. For open joints, we trowel HeatShield CJR or HeatShield 2000 into each joint and tool it flush. For full-surface degradation, we spray or trowel the HeatShield Resurfacing System using the foam-and-mandrel process. For structurally compromised flues, we install the CeCure sleeve with proper termination and transition sealing.
- 4
Crown, cap, and exterior finish. We coat or rebuild the crown, reset or replace the cap, and address any flashing or cricket issues. In Bellevue, this step is non-negotiable. A HeatShield repair without crown protection is a temporary repair.
- 5
Post-application test and documentation. We camera-scan the finished repair, perform a smoke or draft test as appropriate, and deliver your photo record, written scope, and warranty documentation. Clause 4 of the Haven Standard requires this archive. The 365-Day Done Right Promise applies from this date.

FAQs - HeatShield Chimney Cleaning Service in Bellevue
No. We are an independent HeatShield service provider, not affiliated with or authorized by the manufacturer. We use genuine HeatShield compounds and components because the formulation and cure schedule are the system, but we make our own determinations about when a flue is a candidate for HeatShield and when it needs relining or rebuilding instead.
Yes. We use genuine HeatShield ceramic joint repair compound, CeCure sleeve components, and HeatShield 2000 high-temperature repair. We do not substitute generic refractory cement. The thermal properties and bond strength are specific to the formulated product, and substituting risks the same flaking and delamination we are called to fix.
Most standard HeatShield CJR joint repairs in Bellevue are completed in one day, including inspection, preparation, application, and documentation. CeCure sleeve installations typically require two days to allow proper curing and sealing. We book by appointment, not by emergency dispatch, and we text when your technician is on the way.
We service and install HeatShield Ceramic Joint Repair (CJR), HeatShield Resurfacing System, HeatShield CeCure Sleeve, and HeatShield 2000 high-temperature joint repair. If your flue has been treated with a prior HeatShield application of unknown type, our camera inspection identifies the material and its condition before we quote any further work.
HeatShield warranties are typically issued by the installing contractor and cover defects in application. As an independent provider, our work carries the Level Two 365-Day Done Right Promise, not the original manufacturer’s warranty. We document our application process with photos and written scope so any warranty question can be answered with evidence, not memory.
HeatShield service in Bellevue typically ranges from $800-$1,800 for standard CJR joint repair, $1,500-$3,500 for full Resurfacing System application, and $2,800-$5,500 for CeCure sleeve installation depending on flue height and access. Every job starts with a Level 2 camera inspection ($275-$350), which is credited toward the repair if you proceed. We deliver a written price, written scope, and written warranty before any work starts. Call (425) 696-0387 for an exact quote - estimates are free.
HeatShield is a repair product, not a cleaning product. It is a ceramic joint compound and resurfacing system used to restore clay-tile flue liners. Our Chimney Cleaning & Sweep services are the preparation step that must happen first, and our service includes both the sweep and the HeatShield application.
The clay tile must be structurally sound with open mortar joints or surface degradation, not actively spalling or crumbling. Our Level 2 camera inspection determines this tile by tile. In Bellevue and Newcastle, WA, we find that roughly half the flues we inspect in 1960s-70s chimneys need relining or rebuilding rather than HeatShield - we tell you which category yours falls into and quote accordingly.
Sometimes. Smoke smell often indicates drafting problems caused by open mortar joints, a cracked smoke chamber, or a damaged crown letting water into the flue. If the camera inspection shows open joints in sound tile, HeatShield CJR can seal them and stop the odor. If the smell comes from a cracked flue liner, missing cap, or deteriorated firebox, we quote the correct repair for that condition.
The most common causes are application over uncleaned or unprimed tile, application over actively spalling clay, or failure to address the crown and cap that protect the repair from Bellevue’s 37 inches of annual rain. We see all three regularly in Bellevue homes, particularly in Lake Hills and Crossroads where original 1960s chimneys lacked proper crowns to begin with. Our inspection identifies which cause applied to your flue.
Generally no. Gas inserts and direct-vent gas fireplaces use different venting systems and do not have clay-tile flue liners that require HeatShield restoration. However, many Bellevue homes have gas inserts retrofitted into original wood-burning fireplace openings, and the masonry flue above the insert still requires annual inspection and cleaning even though the homeowner considers the fireplace “converted.” We inspect that flue and recommend appropriate service.
