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.

How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner resurfacing in older Shelton colonials near Huntington Center often develops hairline cracking after 10-15 years of thermal cycling through our freeze-thaw winters. The foam layer separates from the clay tile substrate, creating gaps that collect creosote and compromise draft. We strip the compromised foam, recondition the substrate, and apply new Cerfractory coating to factory thickness, or we sleeve with a stainless steel liner if the clay base is too far gone.
- HeatShield UL Listed stainless steel liners (the 316Ti flexible series) can suffer seam separation at the elbows where Shelton’s wet spring cycles accelerate corrosion at the joint. We camera-locate the breach, then either weld-repair the seam with matching 316Ti filler if the damage is localized, or pull a new DuraFlex or Gelco liner as a drop-in replacement when the run is compromised end-to-end.
- HeatShield rigid stainless liners used in straight-shot factory-built chimney rebuilds sometimes shift at the collar connection where the appliance adapter meets the liner. The telltale sign is soot blowback during startup. We reseat the collar with a proper expansion joint, replace the adapter if it’s warped, and pressure-test the assembly before we leave.
- HeatShield poured-in-place flue systems in the 1980s-era raised ranches off Bridgeport Avenue are prone to voids forming where the pour missed during original installation. These hidden pockets trap moisture from Shelton’s heavy coastal air and spall from the inside out. We core-sample the void, then either pressure-grout with HeatShield-compatible refractory or recommend a full liner replacement if the void network is too extensive to trust.
- HeatShield chimney crown and top rebuilds using their refractory crown mix can delaminate when applied over an insufficiently prepared concrete base, which we see often on DIY or cut-rate jobs around the Naugatuck River corridor. We remove the failed crown down to sound concrete, install proper expansion relief, and re-pour with professional-grade refractory or switch to a Gelco pre-formed crown when the chimney configuration allows.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24/7. We book your Level-2 inspection, usually within a few days.
- 2
Camera inspection and documentation. Our tech runs a high-res camera the full length of your flue, photographs every defect, and explains what you’re seeing in plain English. You get the photos.
- 3
Parts decision. If your HeatShield liner can be repaired warranty-safe with OEM components, we quote that. If HeatShield OEM is back-ordered or the design has a known weak point, we quote a quality aftermarket equivalent from DuraFlex or Gelco with equivalent or better spec. You choose.
- 4
The repair. Background-checked, uniformed techs complete most liner replacements and partial rebuilds in one visit. Full chimney rebuilds may need a second day for cure time.
- 5
Testing and verification. We smoke-test or pressure-test every liner installation, run the camera again to confirm the fix, and show you the after photos.
- 6
Written guarantee. The 90-Day Done Right Promise goes in your hand before we leave. If it’s not right, we make it right. No paperwork to dig up, no arguing.
What HeatShield Chimney Liner & Rebuild Costs in Shelton
Most HeatShield liner repairs in the Shelton area fall between $1,800 and $4,500. A partial liner replacement or localized Cerfractory resurfacing typically runs $1,800-$2,800. A full stainless steel liner replacement with removal of the existing HeatShield system runs $3,200-$4,500 depending on flue height, diameter, and whether we need to rebuild the top of the chimney to get a proper seal. Full chimney rebuilds start around $6,500 and scale with height and brick matching.
What moves the price: accessibility (steep roof, tight chase), liner diameter and length, whether the existing clay tile must be removed first, and if the crown or top courses need rebuilding to meet code. We give you the full number before booking. Call (475) 265-6822 for your exact quote - estimates are free.

FAQs
Using an independent service provider does not automatically void your HeatShield warranty, but warranty coverage on the original liner material is typically time-limited and prorated. We document our work with photos and parts receipts so any future warranty claim has a clear paper trail. Call (475) 265-6822 if you want us to review your original installation paperwork before we start.
Many HeatShield components remain available, though some older Cerfractory formulations and collar sizes have been superseded. When OEM parts are unavailable, we source direct-fit equivalents from DuraFlex or Gelco with equal or better thermal and corrosion ratings, and we explain the trade-off before you commit.
The camera tells the story. Localized cracking, minor collar leaks, or thin spots in Cerfractory coating usually justify repair. Multiple breaches, extensive corrosion, or liner separation across more than 30% of the run means replacement is the sounder long-term fix. We show you both options with prices and let you decide.
A compromised liner allows heat, sparks, and combustion gases into surrounding masonry or framing, which is how chimney fires and carbon monoxide intrusion start. That said, not every crack is an emergency. Our inspection separates what needs immediate attention from what can wait a season, and we say so plainly. Call (475) 265-6822 for a free assessment.
Most flexible stainless replacements take four to six hours from setup to final test. A poured-in-place Cerfractory job needs a full day plus 24-hour cure time before firing. Full chimney rebuilds with new liner installation typically span two days. We give you a firm schedule when we quote.
