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.

AfterHeatShield Chimney Liner & Rebuild in Jamaica: What to Know First
We repair, reline, and rebuild HeatShield chimneys in Jamaica as an independent service provider, typically completing most liner work in one to two days once parts are on hand. A HeatShield chimney liner repair or replacement in Jamaica runs $1,800 to $4,600 for most single-flue homes; full rebuilds with masonry work land between $4,000 and $12,000 depending on what the camera shows. We’re not affiliated with or authorized by HeatShield, and we’ll tell you plainly when a problem is manufacturer-related versus age-related.
This page is for homeowners in Jamaica whose HeatShield liner has failed, is leaking flue gas into the house, or was flagged during a Level 2 inspection. If you’re seeing staining, smelling smoke when the fire’s out, or have a report that says the words “compromised liner,” call (516) 240-9612 and we’ll get a camera down your flue.
How HeatShield Products Fail - and How We Fix Them
HeatShield is a cerfractory (ceramic-cement) resurfacing product, not a metal liner. It’s sprayed or troweled over the interior of an existing flue, so how well it holds up depends heavily on the condition of the surface it was applied to. In Jamaica, we see a few recurring failure patterns.
- HeatShield Cerfractory Flue Sealant delaminating from older clay tile liners. Jamaica’s pre-war and mid-century rowhouses near Jamaica Avenue often have original terra cotta flue tiles with spalling (flaking) surfaces. HeatShield was applied over tile that was already degrading, and the bond fails within a few years. The fix is full removal and a DuraFlex stainless steel liner, not another coat of sealant.
- Water intrusion at the flue cap breaking down the cerfractory from the top down. HeatShield rises with moisture and falls with freeze-thaw cycles. Queens winters do real work on a compromised cap. We replace the cap or crown first, then assess whether the HeatShield layer is salvageable or needs a liner replacement.
- Improper application thickness causing cracking and flaking. HeatShield has a required thickness spec. When we put a camera on a flue that was too thinly applied, the product looks like peeling paint. This is an application issue, not a material failure, and the practical fix is a mechanical liner that doesn’t depend on adhesion.
- Gaps where the HeatShield was never applied: smoke chamber and firebox transition areas. HeatShield coverage often stops short of the smoke chamber, which is the hottest and most turbulent part of the system. We parge (coat) the smoke chamber with a proper refractory material or rebuild the chamber if the brick is beyond parging.
- Flue sizing mismatches on older Jamaica homes. Some HeatShield installations were done on flues that were oversized for the appliances they serve. A too-large flue cools flue gas too fast, causing creosote buildup even with a ceramic coating. We correct this with a correctly sized stainless steel liner matched to the appliance’s BTU output.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Camera scan first, always. We run an NFPA 211 Level 2 camera inspection down the flue and record video. You watch it with us. There’s no diagnostic guesswork; the camera shows exactly what’s there. Corrine Halstead has spent two decades running these scans across Jamaica, and she’ll point at the screen and tell you what’s structural, what’s cosmetic, and what can wait.
- 2
Written scope and written price before any work starts. We don’t do verbal estimates. You get a written description of what needs to happen, the material we’ll use, and the dollar figure. If we’re replacing HeatShield with a metal liner, we’ll say why on paper.
- 3
Remove the failed coating or compromised liner. Depending on the condition, we remove what’s loose, vacuum the flue completely, and prepare the surface for either a new liner system or masonry rebuild.
- 4
Install a DuraFlex stainless steel liner or perform the masonry rebuild. DuraFlex is our standard for most replacements. It’s code-compliant, carries a strong manufacturer warranty, and doesn’t depend on bonding to the old flue surface. Where the chimney structure itself is compromised, we do partial or full rebuilds from the roofline up.
- 5
Test and verify. We run the camera again after installation, fire the appliance if it’s safe to do so, and confirm draft and clearance. You get the after photos and the footage.
- 6
Warranty and records. Every job is backed by our 365-Day Done Right Promise. You walk away with a documented photo record under Clause 4 of the Haven Standard, plus your written warranty.

AfterWhat HeatShield Chimney Liner & Rebuild Costs in Jamaica
Straight numbers, because you should know before you call:
- HeatShield camera inspection with written report: $199. This is credited toward any repair work.
- HeatShield removal and single-flue stainless steel liner replacement (DuraFlex): $1,800 to $3,400 depending on flue height and access.
- Smoke chamber parging with refractory material: $500 to $1,200 when done alongside a liner replacement.
- Partial rebuild (crown, top courses, flue cap): $2,000 to $4,500.
- Full chimney rebuild from the roofline up: $4,000 to $12,000 depending on height, scaffolding requirements, and brick matching.
What moves the price in Jamaica specifically: roof access on rowhouses (ladders versus full scaffolding), flue height on attached homes, and whether the existing masonry is structurally sound enough to anchor a liner. Flue height and rooftop accessibility can shift a liner job by $800 or more. Call (516) 240-9612 for a written estimate; there’s no charge for the second opinion if you already have a quote from another company.
Why Jamaica Homeowners Call Level Two Chimney Jamaica for HeatShield Work
We’ve inspected more than 38,000 chimneys since 2009, and every one of them got a written price before work started. That’s not a slogan; it’s our operating rule under Haven Standard Clause 1. When a Jamaica homeowner has a HeatShield liner that’s failing, they call us because we’ll show them the footage, write down what we found, and give them a number that doesn’t change when the crew shows up.
The techs on our Jamaica jobs are background-checked, uniformed, and carry their license information on the page. We also service other liner brands including DuraFlex and Gelco, so if a HeatShield patch is the wrong call, we’ll say so and install the right material instead. Our 365-Day Done Right Promise applies to every HeatShield repair and rebuild. If it’s not done right, we make it right.
FAQs
HeatShield can sometimes be spot-repaired if the delamination is localized and the underlying flue surface is solid, but in most Jamaica homes we see, the failure is systemic once it starts. A camera inspection will tell you within minutes whether patching is viable or whether you’re better off with a stainless steel liner replacement. Call (516) 240-9612 and we’ll show you the footage either way.
We can’t speak for HeatShield’s warranty terms; that’s between you and the manufacturer or original installer. What we can tell you is that our work is backed by our own 365-Day Done Right Promise and the written warranty we issue on every job. If you have your original HeatShield warranty paperwork, bring it to the estimate and we’ll help you understand exactly what it covers.
Most single-flue liner replacements are completed in one to two days once the liner kit is on hand, which is usually within three to five business days of your signed estimate. Masonry rebuilds take longer depending on weather and roof access. We’ll put the timeline in writing when we quote the job.
You need replacement when the camera shows cracks, delamination, or gaps that allow flue gas or creosote to contact combustible framing. You don’t need replacement when the coating is cosmetically imperfect but structurally intact. We will never recommend a liner you don’t need; if a flue is safe, we’ll tell you it’s safe and write that down. The camera doesn’t negotiate - it just shows what’s there. For an honest read on your HeatShield system in Jamaica, call (516) 240-9612.
Yes. Most of the HeatShield repairs we do in Jamaica are on installations done by other companies, many of them gone or unreachable. We don’t need their records; the camera is our record. We’ll document what’s there now and quote the fix based on current condition, not on what the original installer promised.
