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 flue liners crack at the mortar joints after 15-20 winters. West Hartford’s freeze-thaw cycles are hard on any liner, but the Cerfractory composite shrinks slightly more than traditional clay in cold snaps. We see this most in homes near Trout Brook where the water table sits high and chimney moisture lingers. We reline with a compatible stainless system or apply HeatShield’s own resurfacing mix when the flue is structurally sound - never a patch that hides the problem.
- HeatShield UL-Listed gas inserts lose pilot ignition when the thermopile weakens. The SIT valve systems on early 2000s HeatShield inserts were spec’d for a 10-year thermopile life, but West Hartford homeowners often push them to 18. We test millivolt output at the valve before replacing anything. If it’s below 325mV under load, we source the correct OEM thermopile or a Robertshaw equivalent that won’t void your gas train warranty.
- HeatShield wood-burning fireboxes develop spalling at the rear wall where the throat meets the smoke chamber. This is the spot where creosote concentrates and where homeowners in West Hartford’s older homes - the 1920s colonials along Mountain Road and the 1950s ranches off North Main - tend to overfire when temperatures drop below 20 degrees. We pull the damaged refractory, inspect the steel wrapper behind it, and install factory-matched panels or pour a HeatShield-compatible refractory mix when the wrapper is intact.
- HeatShield top-sealing dampers corrode at the cable guide. The cast-aluminum frame holds up fine, but the stainless cable runs through a mild-steel eyelet that rusts from chimney condensation. In West Hartford, where we get 48 inches of rain and snow melt that refreezes in the flue, this is predictable after 12-14 years. We replace the cable assembly with a marine-grade stainless guide or convert to a Gelco damper if the frame itself has warped from a past chimney fire.
- HeatShield fireplace inserts settle and gap at the surround panel. The metal expansion strip compresses over time, and the gap becomes a heat loss path and a carbon monoxide risk. We see this in West Hartford’s split-levels where the fireplace sits on a slab that heaves with frost. We reset the insert on proper hearth pads, seal with high-temp silicone rated to 600°F, and test draft with a manometer - not a guess, a number you can read.
Our HeatShield Fireplace Services Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask the model number if you have it, the symptoms, and whether it’s gas or wood. We book a two-hour window and send a confirmation text.
- 2
Level-2 camera inspection. Our technician arrives uniformed and background-checked. We run a camera up the flue or into the firebox, take photos you can see on the spot, and give you a plain-English verdict. No photos, no recommendation - that’s our rule.
- 3
Parts decision with options. If your HeatShield part is still manufactured, we quote OEM. If it’s obsolete, we explain the aftermarket equivalent and any warranty implications. You choose. We don’t choose for you.
- 4
Repair with documentation. We complete most HeatShield repairs in one visit. Gas valves are leak-tested with a digital manometer. Wood fireboxes are burn-tested for draft. We photograph the finished work.
- 5
Written guarantee and cleanup. You get the 90-Day Done Right Promise in writing - in writing, no arguing. We vacuum, lay down fresh drop cloths, and leave the hearth cleaner than we found it.
- 6
Follow-up. We call within two weeks to confirm the fix held. If something’s off, we come back. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.

Why West Hartford Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve been sweeping and repairing chimneys in West Hartford for over 42 years, and we’ve watched HeatShield products move from a niche liner company to a full fireplace brand. That history matters. We know which HeatShield parts cross-reference to DuraFlex and Gelco components when factory stock runs thin, and we know which repairs are warranty-safe and which ones aren’t worth the paperwork.
Our 90-Day Done Right Promise means if we miss something, we make it right - in writing, no arguing. Our technicians are background-checked, uniformed, and trained to document every job with photos you can see and a plain-English verdict. We’re not a chain, and we’re not a one-truck operator who might answer next year. We’re the company that plans to be in West Hartford in thirty more years, so we act accordingly.
Russell Haines still carries that small notepad in his shirt pocket, sketching flue diagrams mid-job. His crew picked up the habit. It’s a small thing, but it means the person doing the work is thinking while they work - not running through a checklist, but actually solving the problem in front of them. Do it right the first time, or plan on doing it twice.
FAQs
No. As an independent HeatShield service provider, we follow manufacturer specifications and use OEM or equivalent parts. HeatShield’s warranty covers defects in materials and workmanship, not who performs routine service or repair. We document parts by serial number and keep installation records if you ever need to file a claim. Call (860) 743-1516 and we’ll walk you through what’s covered.
Most repairs are completed in a single visit of two to four hours. We stock common HeatShield thermopiles, gas valves, refractory panels, and damper cables on our West Hartford trucks. If your model requires a factory-ordered part, we’ll tell you before we start and schedule the return visit at your convenience. You’ll never wait on a callback - a live person answers our phone 24 hours a day.
We recommend repair when the firebox or flue is structurally sound and the cost is less than half of replacement. For HeatShield inserts over 20 years old with obsolete venting systems, replacement often makes more sense. We give you camera evidence either way - photos you can see, a plain-English verdict - and we’ll tell you plainly when work can safely wait. No scare tactics. No pushed sales.
Gas HeatShield fireplaces should be inspected annually and swept as needed. Wood-burning units need annual sweeping and inspection, per NFPA 211. In West Hartford, where we burn four to five months a year, creosote builds faster in shoulder seasons when fires are small and smoldering. Skipping service risks chimney fire and carbon monoxide intrusion - real hazards, not hypotheticals. The $89 Seasonal Tune-Up catches problems before they become emergencies.
We can source most HeatShield parts manufactured after 1995. For discontinued lines, we maintain cross-reference guides to DuraFlex, Gelco, and other professional-grade brands that fit safely. We never install a part we can’t stand behind, and we’ll tell you if a factory-obsolete system has reached the end of its service life. Call (860) 743-1516 with your model number and we’ll check availability before we schedule.
