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 gas log sets with delayed ignition or soot buildup. The HSI-18 and HSI-24 series common in Seaford split-levels from the 1980s and 90s develop clogged pilot orifices from harbor-area moisture and salt air infiltration. We disassemble the burner, clean the orifice with the correct gauge bit (never a drill bit - we’ve seen that), and test gas pressure at the valve. If the ceramic logs are cracked, we source OEM replacements; aftermarket logs often don’t seat right and cause incomplete combustion.
- HeatShield fireplace inserts with warped firebox panels. The FPI-36 and FPI-42 wood-burning inserts installed in Seaford’s ranch-style homes can develop panel distortion from over-firing, especially when homeowners burn pine or construction scraps. We measure the warp against factory spec; panels within tolerance get refractory cement repair, panels beyond it get factory-matched replacements. We don’t guess - we photograph the gap and show you.
- HeatShield top-sealing dampers that won’t open fully or seal tight. The TSD-200 and TSD-300 series use a stainless cable that corrodes faster in Seaford’s coastal climate than the manufacturer rates for inland use. The cable frays, the cap binds, and you get draft or rain intrusion. We replace with OEM cable where available, or upgrade to a marine-grade equivalent that outlasts the factory part. We test the seal with a smoke pencil and show you the result.
- HeatShield direct-vent gas fireplaces with failed blower motors. The DV-32 and DV-38 units have tangential blowers that collect dust and eventually seize, especially in homes near Seaford’s busier roads. We remove the blower, clean the squirrel cage, test the capacitor, and replace only what’s failed. Many Seaford homeowners don’t realize the blower is optional for operation - we’ll tell you straight if you can safely run without it while we order parts.
- HeatShield firebox refractory cracks that expose metal. In the FB-30 and FB-36 series, thermal cycling from Long Island’s freeze-thaw winters opens hairline cracks that widen each season. We assess with a camera whether the crack is cosmetic or structural. Cosmetic cracks get HeatShield-compatible refractory sealant; structural failures require panel replacement. We document the difference so you understand why one costs $180 and the other costs $1,400.
Our HeatShield Fireplace Services Process
- 1
Call and schedule. A live person answers (516) 614-4632, 24 hours a day. We ask the model number if you have it, the symptoms, and whether the unit is gas or wood. We give you a arrival window and a no-hassle upfront price range.
- 2
Level-2 camera inspection on arrival. Our technician, in uniform and background-checked, photographs the firebox, flue, and any visible HeatShield components. You see the photos on a tablet before we quote the repair.
- 3
Parts decision: OEM or quality aftermarket. We stock common HeatShield wear parts. For obsolete models, we source from our network or fabricate from DuraFlex or Gelco equivalents that meet or exceed factory spec. We explain the trade-off and the price difference.
- 4
The repair, tested before we leave. We complete most HeatShield jobs in one visit. Gas units get combustion analysis; wood units get a draft test. The technician signs off on a checklist you keep.
- 5
Written guarantee and cleanup. Every HeatShield repair is covered by our 90-Day Done Right Promise - in writing, no arguing. We lay drop cloths, vacuum, and leave the hearth cleaner than we found it.

Why Seaford Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve worked on HeatShield equipment in Seaford for long enough to know which serial number ranges had the cable issue, which refractory batches cracked early, and which gas valves fail predictably after twenty years. That knowledge saves you money on misdiagnosis.
Our 90-Day Done Right Promise means if the repair doesn’t hold, we come back. No paperwork to find, no manager to escalate, no argument. Russell Haines put that in writing because he’s been on the other end of a contractor who wouldn’t answer the phone.
We also work with DuraFlex and Gelco systems, so when a HeatShield part is obsolete, we have alternatives that fit and function. Most jobs finish in one visit. A clean chimney is not exciting. That is exactly the point.
FAQs
No - independent service by a qualified technician does not void your HeatShield warranty, provided we use compatible parts and document the work. We are not a HeatShield-authorized dealer, but we service to factory standards and keep records you can submit if a warranty claim ever arises. If your unit is still under original warranty, we’ll flag that and advise whether factory service makes more sense. Call (516) 614-4632 and we’ll check your serial number.
Common wear parts - blowers, cables, refractory panels for current models - we stock or can have within 3-5 business days. Obsolete HeatShield parts require sourcing from aftermarket suppliers like DuraFlex or Gelco, which can take 7-10 days. We tell you before we order, and we don’t charge until the part is in hand and you’re scheduled.
Replace when repair costs exceed 60% of a new comparable unit, or when the firebox is structurally compromised. We assess this honestly - we’ve told Seaford homeowners their 1987 HeatShield insert has another decade in it, and we’ve told others the unit is not worth another dollar. The camera inspection shows you what we see. Call (516) 614-4632 for a free second opinion if another company has recommended replacement.
Gas HeatShield fireplaces: annually, before heating season, to check combustion, clearances, and venting. Wood-burning HeatShield units: annually, or after every cord of wood burned, whichever comes first. Seaford’s coastal air accelerates corrosion on dampers and vent terminals, so we recommend inspection even if you barely use the unit. The $89 Seasonal Tune-Up covers it.
Delayed ignition from dirty burners can crack the glass or damage the valve. A failed vent terminal can introduce carbon monoxide. These are real risks, not scare tactics - we’ve documented both in Seaford homes. That said, if your unit is functioning normally and you’re not using it, the risk is lower. We don’t invent urgency. Call (516) 614-4632 and we’ll tell you whether yours can wait or needs attention now.
