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.
HeatShield Chimney Liner & Rebuild in Plainview: What to Know First
We provide independent HeatShield chimney liner and rebuild service in Plainview, with most jobs completed in a single visit and pricing agreed before we start. A typical HeatShield liner repair runs $1,800 to $3,400; a full rebuild with new stainless steel liner can reach $4,500 to $7,200 depending on height and access. We are not affiliated with or authorized by HeatShield - we are an independent service provider who has worked on their systems across Nassau County for over two decades.
This page is for Plainview homeowners who know they have a HeatShield liner or suspect their chimney was rebuilt with HeatShield materials in the last ten to twenty years. Maybe you have smoke backing up into the living room, or a home inspector flagged something in the flue, or you are buying a house near the Old Country Road corridor and want to know what you are actually getting. Call us at (934) 348-4832. A live person answers, 24 hours a day.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner resurfacing cracks or delaminates. We see this in Plainview split-levels built in the 1970s where the original clay flue was coated rather than replaced. The foam layer shrinks away from the tile during freeze-thaw cycles - common here with Long Island’s wet winters and sudden March thaws. Our fix: we camera the full length, remove loose material, and either re-apply with proper surface prep or recommend a stainless steel liner if the underlying tile is too far gone.
- HeatShield UL Listed stainless steel liners develop seam separation at the flex points. The 316Ti flexible liner works hard in Plainview’s taller colonial chimneys, especially where the flue has an offset to dodge a staircase. After fifteen years of heating and cooling, the corrugation stress at the elbows can split. We source matching gauge replacement sections or, if the damage is isolated, perform a localized repair with proper collar and seal - always pressure-tested before we leave.
- HeatShield Pro-Formance rigid liners show corrosion at the cleanout tee. Condensation collects where the tee meets the vertical run, particularly in homes that burn lower-temperature fires or let the stove smolder. In Plainview, we notice this more in houses with newer, tighter construction that limits draft. We replace the tee with a higher-grade component, verify the chimney is properly capped, and check that the liner is sized correctly for the appliance - an undersized liner is often the real culprit.
- HeatShield factory-built chimney chase covers rust through at the corners. The galvanized steel covers used in some 1990s installations were never going to last thirty years on a Plainview roof. Water gets in, freezes, and the chase framing starts to rot. We replace with a proper copper or stainless cover, rebuild damaged chase walls with water-resistant sheathing, and make sure the new liner terminates correctly - not just shoved through a hole.
- HeatShield parging in smoke chambers fails and falls. The spray-applied parging material can slough off if the original masonry was too slick or oily when applied. We find this in Plainview cape cods where the smoke chamber was never properly shaped to begin with. Our approach: remove the loose material, re-parge with a compatible refractory mix, or recommend a stainless steel liner with proper insulation if the chamber geometry is too far out of spec to fix.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We ask about your symptoms, the age of the system if you know it, and whether you have any prior inspection reports.
- 2
Level-2 camera inspection. Our technician runs a camera the full length of the flue and photographs every joint, offset, and transition. You see the images on a tablet while we explain what we are looking at. No jargon, no surprises.
- 3
Plain-English verdict and options. We tell you whether the HeatShield component can be repaired, needs OEM replacement, or if a quality aftermarket liner from DuraFlex or Gelco makes more sense for your setup and budget. The estimate is the invoice - no add-ons later.
- 4
Repair or rebuild. Our background-checked, uniformed technician arrives with the parts. Most HeatShield liner jobs finish in one day. Full rebuilds may take two if weather or scaffolding is involved.
- 5
Pressure test and documentation. We test the liner for leaks, verify draft performance, and give you photos of the completed work plus a written report for your files.
- 6
The 90-Day Done Right Promise. If something is not right, we come back. In writing, no arguing. That’s the Keystone Standard.
What HeatShield Chimney Liner & Rebuild Costs in Plainview
These are real numbers for Plainview homes based on what we have billed in the last eighteen months. Your exact price depends on chimney height, roof access, and what the camera shows.
| Service | Typical Range |
|---|---|
| HeatShield foam resurfacing repair (localized) | $1,800 - $2,800 |
| HeatShield stainless liner section replacement | $2,400 - $3,800 |
| Full stainless steel liner replacement (flex or rigid) | $3,800 - $5,600 |
| Chimney rebuild with new liner (partial, above roofline) | $4,500 - $6,800 |
| Full chimney rebuild with liner (from ground up) | $6,200 - $9,400 |
What moves the price: three-story chimneys cost more than two-story; scaffolding around a steep slate roof adds labor; switching fuel types (wood to gas or back) requires different liner sizing; and hidden damage to the smoke chamber or firebox only visible after demolition. We price all of this upfront, not after we start.

Why Plainview Homeowners Call Hearthstone Chimney Co. for HeatShield Work
Plainview is full of houses built between 1955 and 1985 with chimneys that were “fixed” once already by someone who is long gone. We have cleaned up after those jobs. Russell Haines, our owner, has spent the better part of two decades running a brush down chimneys across Long Island, including plenty of homes near the Old Country Road corridor in Plainview. He learned the fundamentals at Los Angeles Trade-Technical College before deciding the East Coast had more fireplaces worth working on.
We do not push products. We document, explain, and let you decide. Our 90-Day Done Right Promise is in writing with no arguing. Our technicians are background-checked and uniformed. We stock DuraFlex, Gelco, and HeatShield-compatible components so we are not waiting on a truck from Pennsylvania while your fireplace sits open. And a live person answers the phone at 2 AM on a Sunday if your chimney is backing up smoke - because that is when you actually need us.
If the chimney is doing its job, you won’t think about it once all winter - that’s exactly the point.
FAQs
No, if the work is performed using compatible materials and proper methods - but HeatShield’s original warranty on some older installations has likely expired by now. As an independent HeatShield service provider, we use OEM or equivalent-grade parts and document our work so any remaining coverage stays intact. If your liner is under ten years old, bring your paperwork and we will review it together. Call (934) 348-4832 and we will sort it out.
Yes, for most lines. We maintain relationships with suppliers who stock HeatShield components, and for discontinued series we have cross-referenced DuraFlex and Gelco equivalents that meet the same UL listings. In Plainview, we have successfully sourced replacement sections for HeatShield liners installed as far back as the late 1990s. The camera inspection tells us what we need before we order anything.
The camera does not lie. Isolated cracks, a failed joint, or localized corrosion usually mean repair. Multiple fractures, widespread delamination, or a liner that has pulled away from the top plate means replacement. We show you the footage and explain which category you are in. Sometimes the liner is fine and the real problem is a blocked cap or a damaged crown - we will tell you that too. Call (934) 348-4832 for a free camera inspection.
Most liner replacements finish in one day. A partial rebuild above the roofline typically takes one to two days. A full chimney rebuild from the ground up, including a new liner, runs two to four days depending on weather and scaffold setup. We do not rush masonry - it needs to cure properly, especially in Plainview’s spring and fall temperature swings. We will give you a clear schedule before we start.
A damaged liner lets heat, smoke, and carbon monoxide reach combustible framing. In Plainview’s older homes with balloon construction, that gap between chimney and wall can run uninterrupted from basement to attic. A cracked liner also allows creosote to build in hidden spaces where you cannot see it. We do not scare-sell - we show you the camera footage and let you judge whether the risk is acceptable. Most homeowners who see a split seam at elbow height decide not to wait. Call (934) 348-4832 and we will show you what you are dealing with.
