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.

AfterHeatShield Chimney Liner & Rebuild in Fort Worth: What to Know First
We provide independent HeatShield chimney liner and rebuild service in Fort Worth, typically completing liner replacements in one to two days and partial rebuilds within three to five days depending on masonry cure times. Every job starts with a written price before work begins - no exceptions, no surprises. This page is for Fort Worth homeowners who know they’ve got a HeatShield product in the flue and need to know whether it can be repaired, must be replaced, or if the whole chimney needs rebuilding. Call us at (682) 499-2712 to book a camera inspection and get your written estimate.
How HeatShield Products Fail - and How We Fix Them
HeatShield makes several product lines we’ve encountered across Fort Worth, from the near-west bungalows off Camp Bowie to the 1980s builds around Hulen Mall. Each fails differently, and the fix depends on which one you’ve got and how far gone it is.
- Cerfractory Foam (CF) liner resurfacing: The foam-and-sealant system can delaminate when subjected to repeated thermal cycling - common in Fort Worth, where overnight lows in January drop below freezing while evening fires push flue temps past 600°F. We see this as flaking gray material in the smoke chamber or as a rough, chalky surface on camera. Our fix: mechanical removal of failed foam, then either a fresh CF application if the substrate is sound, or a switch to a stainless or flexible liner if the underlying terra cotta is too compromised.
- HeatShield UL Listing 1777 liner systems: The factory-built stainless liners with proprietary compression fittings can develop gaps at the collar joints after 10-15 years, especially where Fort Worth’s expansive clay soils cause subtle foundation shifts that stress the chimney stack. We spot this as draft irregularities and CO readings that spike during startup. Our fix: collar reseating with OEM compression rings where available, or transition to a DuraFlex or Gelco flexible liner with a proper top plate if OEM parts are back-ordered.
- Terra cotta sleeves with HeatShield refractory coating: Older Fort Worth homes, particularly in the Mistletoe Heights and Berkeley neighborhoods, have terra cotta flues that were coated rather than fully relined. The refractory layer cracks vertically when the underlying clay shifts - we call this “alligatoring” on the camera feed. Our fix: partial rebuild of the affected flue section with new terra cotta, then a full stainless liner if the damage extends below the smoke chamber.
- Smoke chamber parging with HeatShield Chamber-Tech 2000: This product is meant to smooth the corbelled transition from firebox to flue, but it can slump or void if applied over soot-saturated brick - a shortcut we see from previous contractors who skipped the pre-clean. Our fix: full mechanical cleaning to bare brick, moisture testing, then re-parging to NFPA 211 spec with documented thickness readings.
- Factory-built chimney chase covers with HeatShield chase pans: The galvanized pans rust through at the drip edge after 7-12 years in Fort Worth’s combination of summer UV and spring hail. Water intrusion follows, saturating the chase and rusting any stainless liner from the outside in. Our fix: replacement with a properly sized pan in copper or stainless, with integrated spark arrestor, plus liner inspection for external corrosion we document on camera.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Level 2 inspection with camera scan. We run a chimney camera from firebox to cap, recording every flue joint, liner segment, and smoke chamber surface. You get the footage and a written condition report before we quote.
- 2
Parts identification and sourcing decision. We identify your HeatShield product line by visual signature and any stamped markings visible on camera. If OEM HeatShield parts are available through our Haven buying network, we quote them. If lead times exceed two weeks or the part is discontinued, we quote equivalent DuraFlex or Gelco components - always with written specification sheets so you know what you’re getting.
- 3
Written price, scope, and warranty delivered. Clause 1 of the Haven Standard: the price is on paper, the scope is itemized, and the 365-Day Done Right Promise is stamped on the document. Nothing starts until you sign.
- 4
Repair or rebuild execution. Liner pulls are done with controlled descent to protect the masonry. Rebuilds are staged with proper cure times between courses - we don’t accelerate mortar set with heaters, because Fort Worth’s dry winter air already pulls moisture too fast.
- 5
Post-work testing and documentation. Smoke test, draft measurement, and a second camera run to verify liner integrity. Photos, readings, and the completed warranty go in your file - Clause 4 of the Haven Standard, the archive practice we’ve kept since 2009.
- 6
Cleanup and final walkthrough. We leave the work area cleaner than we found it. Corrine Halstead’s standard: “The camera doesn’t lie - and neither does the written estimate.” You get both before we pack up.

AfterWhat HeatShield Chimney Liner & Rebuild Costs in Fort Worth
These are the ranges we see on actual HeatShield jobs in Fort Worth, based on 38,000+ inspections and cleanings since 2009:

What moves the price: accessibility (steep roof pitch, tight lot lines in the Berkeley or Fairmount districts), extent of terra cotta damage below the roofline, and whether the chase or crown needs simultaneous repair. We don’t guess - the camera shows us exactly what we’re dealing with. Call (682) 499-2712 for your free estimate; every quote is written, itemized, and delivered before any work begins.

Corrine Halstead grew up in Queens, trained at Apex Technical School in Manhattan, and has spent the better part of two decades running chimney crews across Fort Worth.

FAQs
HeatShield’s original warranty applies to defects in materials and factory application; it does not cover field repairs or aftermarket modifications. As an independent service provider, we document our work with photos and written scope so you have a clear record of what was done and when, which protects your interests regardless of OEM coverage status. Call (682) 499-2712 if you need help interpreting your original warranty paperwork.
We source OEM HeatShield components through our Haven buying network when available and when lead times are reasonable - typically under two weeks. If OEM parts are back-ordered or discontinued, we quote equivalent DuraFlex or Gelco liners with full specification sheets so you can compare. The choice is yours, and it’s always in writing before work starts.
The camera decides. Surface cracking or minor delamination in accessible sections often qualifies for localized repair. If the damage extends below the smoke chamber, involves multiple flue joints, or shows external corrosion from water intrusion, we recommend full liner replacement - and we’ll show you exactly why on the footage. Nothing is sold without evidence you can see for yourself.
Most liner replacements are completed in one to two days. Partial rebuilds requiring masonry cure time take three to five days. Full rebuilds from the roofline up, common in Fort Worth’s pre-1960 stock with compromised chimneys, run five to seven days depending on weather and mortar cure. We don’t rush cure times - compressed schedules crack mortar, and cracked mortar fails inspection.
A compromised flue liner allows heat, sparks, and combustion gases into the chimney walls - in Fort Worth’s dry winter conditions, that means elevated fire risk and potential CO migration into living spaces. The hazard is real, but so is the cost of premature replacement. Our camera inspection tells you whether the condition is urgent or monitorable, with a written timeline so you can plan. Call (682) 499-2712 to schedule - estimates are free, and the price is on paper before any work begins.
