We restore safe venting with UL-listed stainless steel liner systems and HeatShield cerfractory sealant repair, matched to your appliance and confirmed by a video scan before and after. ## What Chimney Relining Actually Does Your chimney’s flue liner is the layer that keeps combustion gases inside the chimney and out of your walls, framing, and living space. When clay tiles crack or a metal liner corrodes, three bad things start happening: heat escapes into combustible framing, smoke sneaks into rooms, and — most dangerously — **carbon monoxide** can vent inside instead of up and out. Relining fixes it. We use two proven, UL-listed methods depending on what a video scan shows. ## Method 1: Stainless Steel Sleeve Relining For badly deteriorated or unsafe liners, we install a **stainless steel liner** system: - **316 Ti stainless steel** for wood-burning fireplaces and stoves - **304 or AL29-4C stainless** for high-efficiency gas and oil appliances - **Insulation wrap** around the sleeve to improve draft and keep flue-gas temperature up - **Proper termination** at the top with a rain cap and storm collar - **Sized to the appliance** — an oversized liner condenses and corrodes; an undersized one restricts draft Every stainless install comes with the manufacturer’s warranty (often a lifetime warranty for wood appliances) and a written note in your file. ## Method 2: HeatShield Cerfractory Sealant Not every liner has to come out. If your existing clay flue tiles are structurally sound but have hairline cracks, gaps at the joints, or minor missing mortar, **HeatShield** is a great fit. It’s a **cerfractory sealant** — a ceramic-and-refractory hybrid — applied from inside the flue with specialized tools. Three HeatShield systems handle three severities: - **Joint repair** — sealing gaps between clay tiles - **Resurfacing** — thin protective coating over the entire flue interior - **CeCure Sleeve** — thicker structural sleeve for more damaged flues HeatShield preserves the original masonry, is more affordable than full stainless in the right situations, and typically completes in a single day. ## Before-and-After Video Scans Every relining job at West Hartford Chimney Repair starts with a Level 2 video scan [/chimney-inspections/ →](/chimney-inspections/) that documents the existing damage. We do a second scan after the work so you have a clear before/after record for your file and, if you’re selling, for the buyer’s home inspector. ## When Relining Is Required by Code Connecticut generally requires a properly sized liner: - After installing a new gas furnace or high-efficiency appliance - After a chimney fire - When an inspection finds through-tile cracks or missing tiles - When converting from oil to gas or vice versa If you’re not sure, request a free virtual assessment and we’ll tell you honestly whether relining is required or genuinely optional. ## What’s Included - UL-listed stainless steel (316 Ti / 304) liner installation - HeatShield cerfractory joint & sleeve repair - Video-scan confirmation before & after - Liner sizing for wood, gas & oil appliances - Insulation blanket wrap for efficiency - Written manufacturer warranty pass-through ## Recent Work ![Coil of stainless steel chimney liner ready for installation](/images/features/coil-of-316-ti-stainless-steel-chimney-liner-ready.webp)![Cracked clay flue tile visible on a video scan monitor](/images/features/cracked-clay-flue-tile-visible-on-chimney-video-sc.webp)![HeatShield cerfractory sealant being applied to repair a flue liner](/images/features/heatshield-cerfractory-sealant-being-applied-to-ch.webp)![Completed stainless liner installation and termination at the chimney top](/images/features/completed-stainless-liner-installation-at-top-of-c.webp) Our Process ## How Our Chimney Service Works Simple, transparent, and safe from booking to cleanup. 01 ### Free Estimate Schedule online, by text, or by phone.

They were out the next morning, traced it to the flashing, and fixed it same day. Clean, professional, and fair pricing.” > “Our 1920s chimney needed a full rebuild. The crew rebuilt it beautifully and then washed the roof and raked the lawn afterward. You'd never know they were here, except the chimney looks brand new.” > “Booked a sweep and inspection by text. The tech laid down drop cloths, used a HEPA vacuum, and showed me the video scan of the flue. Genuinely the most thorough chimney company I've used.” ## Questions About Chimney Relining ### Do I really need a chimney liner? + In most cases yes. Cracked or corroded liners let heat, smoke, and carbon monoxide escape into your home. Modern code often requires a properly sized liner for gas and oil appliances too. A video scan tells us for sure. ### Stainless steel or HeatShield — which is right for my chimney? + If the existing liner is essentially destroyed, we install a UL-listed stainless steel sleeve. If the clay tiles are mostly sound but have cracks or bad joints, HeatShield cerfractory sealant restores them without ripping out the old liner. A video scan confirms which fits. ### How long does a stainless steel chimney liner last? + A quality 316 Ti stainless steel liner installed with a proper insulation wrap typically carries a lifetime warranty for wood-burning appliances and 15+ year warranties for gas and oil. Real-world life is usually decades. ### Can you reline a chimney without tearing down the brick? + Yes. Both stainless steel sleeves and HeatShield installations happen from the top and inside — no exterior masonry demolition. That's why we often recommend relining instead of a full rebuild when the structure is otherwise sound.
