HeatShield Chimney Cleaning in Glendale, CA
We provide independent HeatShield chimney cleaning and service throughout Glendale, and the one thing that makes our HeatShield work here different is that we see more earthquake-cracked 1920s brick flues than nearly any other failure type. Before any HeatShield coating goes in or gets cleaned, we run a camera through the flue because a liner poured over cracked, leaking mortar will delaminate within a season or two. Call (833) 589-9860 for a free estimate from a crew that repairs what it finds, not just what you called about.
Why Glendale Residents Choose Us for HeatShield Service
We have mixed and applied HeatShield ceramic restorative across hundreds of old brick flues, and we have learned its limits in Glendale’s cracked, earthquake-scarred masonry. HeatShield is not a factory-mounted product you can “authorize” – it is a repair-and-relining system we apply by hand, and we know exactly when a resurfacing will hold and when the tile bed is too far gone to pour over. Dennis Duran, our owner, trained in building and construction technology at Los Angeles Valley College and spent the better part of a decade in the trade before starting Ashford Chimney Sweep in 2012. That matters when you need someone who will tell you the coating is the wrong call and a rebuild is the right one.
We are an independent HeatShield service provider in Glendale – not manufacturer-affiliated or authorized. We mix HeatShield only from manufacturer-supplied powder to spec, and we match the ceramic consistency to your flue’s diameter. Where the tile bed has failed, we recommend rebuild or a proper stainless liner instead of coating over damage. We would rather lose a job than pour a coating over a flue that needs repointing first.

Common HeatShield Chimney Cleaning Problems We Solve in Glendale
- Cured HeatShield liner delaminating from the tile. This is the Glendale classic. The flue was damp or oil-soaked when the coating was poured because cracked mortar has been leaking since the 1994 Northridge earthquake. We strip the failed section, dry the flue, repair the mortar behind it, and recoat only when the substrate is sound.
- Glazed third-degree creosote bonding over an existing HeatShield surface. Glendale’s dry, warm summers and long idle stretches between the October-January burn season let soot and creosote harden into a shiny, rock-hard glaze. Aggressive mechanical scraping scars the liner, so we use chemical softening first and take our time. The chimney doesn’t lie – it shows you exactly what’s been going on up there.
- Sintered or spalled original bricks behind a liner. When the crown or flashing failed, water traveled behind the resurfaced coating and puffed it loose. We find the water entry point at the crown or cap, fix it, then address the brick face before any new coating goes down.
- Rusted or collapsed dampers and smoke-shelf blockages. A sound liner cannot fix smoke rollback caused by a collapsed damper or a smoke shelf packed with debris. We clear the blockage and repair or replace the damper as its own repair – no coating masks that problem.
- Fire-wood rat nests and palm frond debris on the smoke shelf. After a Santa Ana wind, north Glendale chimney tops collect everything the wind pushed up there. We check every chimney top before cleaning because a hidden nest above a HeatShield surface means smoke rollback and a house full of soot on the first fire. The liner is usually fine – it is what landed on top of it that needs clearing.
HeatShield Service in Glendale: What Local Conditions Mean for Your Equipment
North Glendale is where nearly all the HeatShield work lives. The foothill streets in 91208 and the surrounding hillside neighborhoods are dominated by 1920s-1940s single-family homes and small duplexes with original brick and stucco chimneys, and those chimneys have spent thirty years quietly cracking since the Northridge earthquake. When we take a HeatShield call in those neighborhoods, we assume the flue has hidden mortar cracks until the camera proves otherwise. A huge share of north-side foothill HeatShield calls start as a coating estimate and end as repointing or rebuild work after a camera run shows the cracks behind the tile. That is not a sales tactic – it is what the camera shows, and we show you the footage before we recommend a dollar of work. To be blunt, the ratio of coating estimates to repointing jobs is high here, and any Glendale sweep who skips the camera before coating is doing you a disservice.
HeatShield Models & Products We Service in Glendale
Our Glendale crews service every HeatShield product you are likely to have in an older foothill chimney: HeatShield ceramic liners, the pourable refractory resurfacing blend we mix from manufacturer-supplied powder; HeatShield CeCure patch and repair compound for smaller breaches and spalled sections; and HeatShield Flexisoot/Thermix flue liners where a flexible liner is the right call. We do not stock factory or “genuine” HeatShield parts as a dealer would. We are an independent shop that repairs, installs, and services HeatShield equipment with quality parts that fit the flue diameter and the condition of the tile bed. When the tile bed is sound, a HeatShield coating is money well spent. When it is not, we tell you plainly and quote the rebuild or stainless liner instead.

AfterHeatShield Service Pricing in Glendale
HeatShield chimney cleaning and service pricing in Glendale is set per job by written estimate, never by a flat rate sheet. A full chimney sweep with a camera inspection typically runs $250-$450 for a single-flue brick chimney. Adding a HeatShield coating is costed by flue diameter and vertical length, and the estimate includes the Level 2 camera work, the repointing or crown repair if needed, and the coating materials and application. Anything that pushes the price up – heavy third-degree creosote needing chemical softening, a delaminated liner section needing strip and recoat, a smoke-shelf debris removal – should show up as its own line item. The free estimate includes the camera check, so you know what the flue actually needs before you approve a dollar. Call (833) 589-9860 for an exact quote.

FAQs – HeatShield Chimney Cleaning in Glendale
Not by itself. HeatShield is a flue resurfacing product – it coats the inside of the flue tile, but it cannot close cracks in the mortar joints behind the tile or in the brick structure. If the camera shows Northridge-era mortar cracks, we repoint the cracked joints and repair the crown first, then apply the HeatShield only after the flue passes a second camera check. Coating over active cracks means water keeps traveling behind the liner and the coating puffs loose within a few seasons. Call (833) 589-9860 to schedule a camera check before any coating estimate.
Yes. We will not write a HeatShield estimate in Glendale without running a Level 2 camera through the flue first. The 1994 Northridge earthquake left most old foothill brick chimneys with some degree of hidden mortar damage, and a coating estimate without a camera is a guess. The camera run is part of the free estimate, and you see the footage yourself. If the flue is clean and sound, the estimate is straightforward. If it is not, you will know exactly why before spending anything.
We use chemical softening first, never aggressive mechanical scraping. Hard, glazed third-degree creosote is common in Glendale because fireplaces sit unused for months, letting creosote bake and harden in the heat. Wire brushing or rotary scraping a HeatShield surface to remove that glaze will scar and weaken the ceramic. We apply a creosote softener, let it work, then remove the residue gently. The liner stays intact and the flue actually gets clean. Call (833) 589-9860 to ask about chemical creosote removal for your HeatShield-lined flue.
Only if the smoke rollback is coming from a rough or misaligned flue surface. In many small 1930s Spanish Colonial fireplaces in Glendale, smoke rollback comes instead from a collapsed damper, a blocked smoke shelf, or a firebox opening that is simply too tall for the flue’s draw. A HeatShield coating smooths the flue surface but cannot fix a damper that won’t open or a smoke shelf packed with debris. We diagnose the actual cause with a camera before recommending a liner, because coating the flue when the problem is the damper or shelf would waste your money and still smoke you out.
Most landlords in the north foothills need a written chimney inspection showing the flue is safe before a tenant moves in, because chimney cleaning here is overwhelmingly a landlord-and-tenant, pre-rental-safety-check business. A HeatShield coating alone is not an inspection. We recommend a Level 2 camera inspection plus a sweep. If the camera turns up Northridge mortar cracks, a rat nest, or glazed creosote, we give you a written report and a repair quote. You can hand that to a tenant or keep it for your records.
