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 Fireplace Services in Greenwich: What to Know First
HeatShield fireplace service in Greenwich typically runs $185 to $475 for most repairs, with full ceramic refractory restoration between $900 and $2,400 depending on firebox size and damage extent. We complete most HeatShield repairs in a single visit, and every job gets a written price before we touch a tool. If you own a fireplace with HeatShield mortar or refractory panels and you’re seeing cracked joints, spalling, or staining around the firebox, this page covers what’s actually going on and what it costs to fix. Call (516) 399-5497 for a free estimate.
Corrine Halstead runs our Greenwich operation, and she’s been documenting failed HeatShield applications in Fairfield County long enough to recognize the patterns before the camera finishes its first pass. This page is for homeowners in Greenwich, Cos Cob, Riverside, and Old Greenwich who want to know whether their HeatShield coating is failing, whether it’s covered, and what a straight repair looks like.

How HeatShield Products Fail - and How We Fix Them
- Cerfractory flue joint separation (HeatShield Cease-Fire and Joint Repair System). In Greenwich homes built before 1980, thermal cycling wrecks the bond between HeatShield’s cerfractory material and the original clay liner. You’ll see hairline cracks at the mortar joints first, often upstairs near the flue midpoint. The fix is heat-cured joint sealing with HeatShield’s own repair compound, but only after we camera-scan to confirm the liner hasn’t shifted. If it has shifted, no amount of sealing holds, and we’ll tell you that plainly.
- Smoke chamber parging delamination (HeatShield Smoke Chamber Repair System). HeatShield’s parging mix bonds poorly to smooth, glazed clay tile in the smoke chamber, which describes most mid-century Greenwich colonials. The coating flakes off in sheets within three to five years. We remove what’s loose, re-profile the corbels, and reapply with proper surface prep, and we photograph every layer before the next one goes on.
- Firebox refractory panel cracking (HeatShield Firebox Repair Panels). The panels HeatShield supplied for zero-clearance and masonry fireboxes fail most often at the back wall seam, where the panel meets the floor brick. Greenwich’s humid summers, followed by dry winter air, cause repeated expansion and contraction. When the seam opens, heat reaches the framing. We replace the panel and re-seal the seam with high-temp refractory caulk rated for direct flame contact.
- Cerfractory wash-out in the firebox floor (HeatShield Firebox Floor Repair). If you burn wood, the floor takes the worst of it. Ash retains moisture, moisture eats the cerfractory bond, and you get a pitted, crumbling floor within a few seasons. We grind out the degraded material, re-cast with HeatShield’s floor compound, and document the thickness with a probe reading so you see the number yourself.
- Damper area flaking and rust staining (HeatShield Damper Repair Applications). HeatShield’s heat-resistant coating around the damper housing can spall when the damper’s cast-iron frame rusts underneath, which happens in Greenwich because the marine air accelerates oxidation on uncoated iron. We remove the compromised damper, treat the surrounding masonry, install a new top-sealing damper if that’s the better long-term fix, and quote that in writing before any work starts.
Our HeatShield Fireplace Services Process
- 1
Call and describe what you’re seeing. A live person answers, 24/7. We schedule the visit and assign a named tech, who texts you when they’re on the way.
- 2
Camera-scan inspection, always first. Clause 4 of the Haven Standard requires a photo record on every job. We run a camera down the flue and through the firebox before we quote anything.
- 3
We show you the photos. Not a verbal summary. You see the cracked panel, the delaminated parging, the joint separation, on our screen. Corrine’s rule: the camera doesn’t guess. Neither do we.
- 4
Written scope, written price, written warranty before work starts. Clause 1 of the Haven Standard. You get the breakdown: HeatShield OEM product vs. quality aftermarket, labor, timeline, warranty terms. No verbal estimates, no surprises.
- 5
Repair with HeatShield materials, sourced through Haven’s buying network. We use HeatShield’s own compounds and panels where the application calls for them, and we’re realistic with you about when DuraFlex or Gelco components make more sense.
- 6
Post-repair test and full photo documentation. We run the cycle again, take fresh photos of the completed work, and hand you the documented record. The 365-Day Done Right Promise applies: if it’s not done right, we make it right.
BeforeAfterWhat HeatShield Fireplace Services Costs in Greenwich
Here’s what we quote most often on HeatShield repairs in Greenwich:
- Camera-scan inspection (Level 2, NFPA 211): $95-$195, depending on flue height and firebox access
- Firebox panel replacement (HeatShield panel, standard masonry firebox): $185-$425 per panel, installed
- Smoke chamber parging repair (HeatShield Smoke Chamber System): $750-$1,600
- Flue joint sealing (HeatShield Joint Repair System, single story): $250-$550 per joint section
- Full firebox ceramic refractory restoration (HeatShield Firebox Repair, complete): $900-$2,400
- Damper housing repair with HeatShield coating: $325-$650
What moves the price: firebox size, how much material has to be ground out, whether the smoke chamber needs full re-profiling or spot repair, and whether we’re dealing with one joint or eight. Greenwich’s older colonials near Cos Cob tend to have bigger fireboxes and more eroded joints than the newer builds up in backcountry. Every quote is written, itemized, and handed to you before work starts. Call (516) 399-5497 for a free estimate.
Why Greenwich Homeowners Call Level Two Chimney Greenwich for HeatShield Work
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and we’ve been documenting HeatShield failures on camera that entire time. Our techs know which HeatShield applications hold up in Greenwich’s marine climate and which ones don’t, and they’ll tell you the difference without softening it. We carry HeatShield products alongside DuraFlex and Gelco components, so if the honest answer is that a HeatShield patch won’t hold and a DuraFlex liner will, we’ll say so and quote both options in writing. The 365-Day Done Right Promise stamps every job. Background-checked, uniformed techs. License information on every page. A live person answers the phone, day or night. And the Free Second Opinion stands: bring us a competitor’s written estimate and we’ll review it with you.
FAQs
HeatShield products carry a limited manufacturer warranty that covers material defects, but it does not cover labor, and it’s voided by improper installation or use. As an independent HeatShield service provider, we don’t process manufacturer claims. What we do is document the failure on camera, give you a written explanation, and quote the repair whether or not the warranty applies. Call (516) 399-5497 and we’ll walk you through what your option set really looks like.
Most standard HeatShield panels and compounds are in our Greenwich shop inventory, so we can usually repair in a single visit. Custom-sized panels for unusual fireboxes take three to seven business days through Haven’s buying network. We’ll give you a parts lead time on the written quote, so you know before you commit.
It depends on the liner you have under the coating. If the original clay liner is intact and only the HeatShield joints have separated, a joint repair is appropriate. If the camera shows the clay liner cracked and shifting, or the HeatShield parging has adheared poorly from day one, a DuraFlex stainless liner is the honest long-term fix. We’ll show you the photos and quote both, in writing, before you decide.
For specific repairs, HeatShield cerfractory performs well when prepped and applied correctly. But we’re honest when it won’t hold. In Greenwich, where the freeze-thaw cycle inside unlined chimneys is brutal, HeatShield as a full resurfacing on a badly degraded flue often fails faster than repointing to a DuraFlex liner. We’ll quote what’s actually right for your flue, in dollars, on paper.
