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.
HeatShield Chimney Repair in Fort Worth: What to Know First
We provide independent HeatShield chimney repair in Fort Worth, typically scheduling within 3-5 business days and delivering a written price before any work starts. Most HeatShield repairs run $850-$2,400 depending on whether we’re addressing liner joint separation, smoke chamber parging, or full crown rebuild. Corrine Halstead and our crews have handled HeatShield systems across Fort Worth since 2009, from the 1920s bungalows near the Cultural District to newer builds in Walsh Ranch where the Cerfractory Foam line was spec’d for its lightweight pour.
This page is for you if you know you’ve got a HeatShield product and something’s not right - a draft that won’t hold, a smell of smoke in the room, or a previous sweep who told you the liner “looks fine” without running a camera. Call (682) 499-2712. We’ll send a written estimate. No charge for the look.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam liner joints separate in Fort Worth’s clay soils. The foam-and-cement slurry cures hard, but the freeze-thaw cycle in our North Texas winters - especially after a wet spring like 2024’s - lets ground movement telegraph up the stack. We find hairline gaps at the collar joints, sometimes three courses up from the smoke chamber. Our fix: camera-locate the breach, remove failed material back to sound substrate, and repour with matching Cerfractory Foam or transition to a stainless DuraFlex liner if the damage pattern repeats.
- Cerfractory Flue Coat spalls where creosote burns in. This spray-applied liner is rated to 3,000°F, but Class III glazed creosote (the shiny, tarry stuff from slow burns) traps acids against the surface. In Fort Worth, we see this most in fireplaces used for “atmosphere” fires - low and smoldering on 50-degree January evenings. The coat flakes in sheets. We scarify to bare brick, neutralize the acid residue, and reapply to HeatShield’s specified thickness, then document the finished mil depth in your photo record under Haven Standard Clause 4.
- Smoke chamber parge fails at the shoulder angle. HeatShield’s Smoke Chamber Repair (SCR) system is designed to smooth the corbelled brick where the firebox meets the flue. When the parge separates, smoke eddies instead of drafting straight up. We find this in Fort Worth’s 1960s-1980s ranch homes with original Rumford-style throats that were never properly shaped. Our fix: rebuild the shoulder with SCR-2000 compound, tooling it to NFPA 211’s 1:10 slope standard, then flow-test with a smoke pencil.
- CrownSeal cracks over HeatShield’s poured crowns. HeatShield’s CrownCoat and CrownSeal products flex, but Fort Worth’s summer UV index - among the highest in Texas - degrades the acrylic topcoat in 4-6 years if not maintained. Water enters, freezes at the flue collar, and pops the crown. We strip to concrete, assess the underlying pour for soundness, and reseal with fresh CrownSeal or recommend a cast-in-place concrete crown with drip edge if the structural pour is compromised.
- Factory-built collar gaps on HeatShield ProLiner retrofits. The ProLiner stainless system is excellent when properly sleeved, but we’ve found collar-to-flue misalignments in Fort Worth homes where the original installer didn’t account for our local 8-inch common brick vs. the 7.625-inch modular used in HeatShield’s training mockups. A 3/8-inch offset doesn’t sound like much until smoke finds it. We recollar with custom-fabricated stainless or transition to a Gelco top plate when the ProLiner termination can’t be salvaged.
Our HeatShield Chimney Repair Process

- 1
Call and schedule. A live person answers. We ask the HeatShield product name if you know it, the year of installation if you have it, and what you’re seeing. We book a Level 2 inspection, not a “sweep and look.”
- 2
Camera-scan inspection. Our tech runs the flue camera from firebox to cap, 360-degree rotation at every joint and transition. We record the footage and stamp it with date, time, and property address. Clause 4 of the Haven Standard requires this; we’ve done it since 2009.
- 3
Written price before work. Corrine reviews the findings, specs the repair, and sends a written scope with line-item pricing and warranty terms. You approve or you don’t. No charge if you decline. The camera doesn’t lie - and neither does the written estimate.
- 4
Parts decision: OEM or quality aftermarket. For HeatShield repairs, we source Cerfractory Foam and CrownSeal through our Haven buying network when the job calls for material match. Where the original product has failed repeatedly, we may recommend DuraFlex stainless or Gelco components - always with the trade-off explained in writing.
- 5
Repair and test. We execute to HeatShield’s published cure times and temperature ratings, then smoke-test or flow-test depending on the repair type. The tech photographs the finished work.
- 6
Documentation and follow-up. You receive the photo record, the written warranty, and a 365-Day Done Right Promise card. We call at 90 days to check performance.

Why Fort Worth Homeowners Call Level Two Chimney Fort Worth for HeatShield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a written price before work started and a documented record when done. That volume matters for HeatShield owners because we’ve seen how Cerfractory Foam behaves in Fort Worth’s gumbo clay after a wet year, and we know which 2017-2019 ProLiner installs in the Fairmount district are due for collar inspection.
Our techs are background-checked, uniformed, and assigned by name - you’ll get a text when yours is en route. We carry DuraFlex, Gelco, and HeatShield materials in our buying network, so we’re not forcing a brand match when a different solution serves you better. The 365-Day Done Right Promise covers every repair: if it’s not right, we make it right, period. That’s Haven Standard Clause 1 through 5, and it’s how we’ve operated from the first day.
FAQs
Using an independent HeatShield service provider like Level Two Chimney Fort Worth does not automatically void your warranty, but warranty coverage depends on whether the original install was registered and whether the repair follows HeatShield’s material and cure specifications. We document our process to those specs in your photo record. If warranty transfer is important to you, we’ll note it on your written scope and preserve the paper trail. Call (682) 499-2712 and we’ll check your install date against HeatShield’s registration window.
We source Cerfractory Foam, CrownSeal, and SCR-2000 through our Haven buying network, which procures from HeatShield-authorized distributors. For some repairs - particularly ProLiner collar transitions - we may recommend DuraFlex or Gelco stainless components that exceed OEM specs at a lower installed cost. We always explain the trade-off in writing before you decide.
Repair is viable when the damage is localized - a separated joint, spalled surface area under 30% of the liner, or crown cracking above sound concrete. Full replacement with stainless or re-pour becomes the honest recommendation when we find multiple joint failures, structural movement in the surrounding masonry, or acid degradation through the full Cerfractory thickness. The camera shows which category you’re in; we don’t guess. Call (682) 499-2712 for the inspection - estimates are free.
Most localized repairs - joint sealing, crown reseal, smoke chamber parging - finish in one day. Cerfractory Flue Coat resurfacing requires a 24-hour cure before firing, so we schedule a next-day verification. Full ProLiner transitions or extensive crown rebuilds may run two days. We give you the timeline in writing with the price, not after we start.
A separated liner joint or cracked crown lets combustion gases leak into wall cavities and living space - carbon monoxide risk, not just draft loss. Spalled Flue Coat exposes brick to direct flame contact, which can transfer heat to adjacent framing. That said, we don’t invent urgency: if the camera shows a hairline crack with no gas leakage in testing, we’ll tell you and schedule recheck in 12 months. When the finding is immediate, we say so plainly and show you the image. Call (682) 499-2712 - we’ll run the camera and give you the real condition, not a sales pitch.
