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 Foam liner resurfacing cracks or delaminates in the smoke chamber. The foam application shrinks slightly during curing, and in Framingham’s freeze-thaw cycles - especially in unlined exterior chimneys on colonials near the Sudbury River - that shrinkage opens hairline gaps by year three or four. We camera-scan to confirm delamination depth, then re-apply Cerfractory Foam to manufacturer thickness or recommend a stainless liner if the underlying terra cotta is too compromised.
- HeatShield UL Listed relining systems develop joint separation at the flue collar. The 316Ti stainless collars on HeatShield’s relining kits can work loose where they meet the appliance adapter, particularly on wood-burning inserts that get cycled hot-to-cold daily. We find this on camera as a gap that pulls smoke during draft testing. Our fix: remove and re-seat the collar with fresh high-temp sealant, or replace with an OEM HeatShield collar if the original is warped.
- HeatShield gas log sets in factory-built fireplaces suffer burner port corrosion. The #24 sand-cast burner used in several HeatShield gas fireplace series collects condensation in Framingham’s humid summers when pilots stay lit but flues don’t warm enough to dry the firebox. Ports clog, flames yellow, and CO readings climb. We pull the burner, gauge port diameter against spec, and either clean and re-drill to OEM size or source a replacement through Haven’s buying network.
- HeatShield damper assemblies seize in the open position after creosote infiltration. The cast-iron throat dampers original to many HeatShield wood-burning fireplaces bind when Class II or III creosote - the tarry, baked-on kind - drips from the smoke shelf and cakes the hinge pin. We don’t just free it with a hammer. We camera the smoke shelf, measure creosote thickness, clean to NFPA 211 standard, then replace the damper with a HeatShield-compatible top-sealing damper if the throat frame is pitted.
- HeatShield firebox panels spall and expose refractory seams. The pumice-concrete panels in HeatShield’s prefab wood-burning units flake when subjected to over-firing, which happens more than you’d think in Framingham when homeowners burn green oak or maple from local tree services. We measure panel thickness at six points, compare to minimum spec, and install OEM HeatShield panels or source matching refractory from our Copperfield and Famco suppliers if the series is discontinued.
Our HeatShield Fireplace Services Process

- 1
Call and schedule. A live person answers, 24/7. We ask the HeatShield series or model if you know it, the fuel type, and what’s happening. We book a window and text you when Corrine or your assigned tech is en route.
- 2
NFPA 211 Level 2 inspection with camera. We run a camera from firebox to cap, record the full flue, and photograph the firebox, damper, and any HeatShield labels we find. You get the footage. Clause 4 of the Haven Standard requires this documented photo record on every job - we’ve done it since 2009.
- 3
Written price, written scope, written warranty. Before any tool touches your fireplace, we deliver a flat price for the repair or service, the exact parts we’ll use (OEM HeatShield or equivalent from DuraFlex, Gelco, or Olympia Chimney), and what the 365-Day Done Right Promise covers. Haven Standard Clause 1: have it in writing.
- 4
The work. Background-checked, uniformed technicians complete the repair or service. For HeatShield liner work, we verify curing temperatures and times. For gas service, we combustion-test and check gas pressure at the valve.
- 5
Final camera run and documentation. We re-camera to confirm the fix, deliver your photo record and written warranty, and collect payment only after you’ve reviewed everything.
- 6
Follow-up. We call within 30 days on major repairs. The 365-Day Done Right Promise stays in force - if it’s not done right, we make it right.

Why Framingham Homeowners Call Level Two Chimney Framingham for HeatShield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of them in Framingham run HeatShield components. Corrine Halstead learned this trade through the masonry and construction technology program at New York City College of Technology, and she’s spent the better part of two decades on roofs and in fireboxes across MetroWest - including older colonials near Cushing Memorial Park that throw a surprise at every camera drop.
We don’t guess at HeatShield repairs. We camera-scan, measure, and write the price before work starts. If your HeatShield series is discontinued, we source compatible materials through our Haven buying network with DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield - never a mismatch that voids what warranty you have left. And if another company already gave you a quote that doesn’t sit right, bring it in. Our Free Second Opinion is exactly that: free, written, and honest about whether the work can wait.
FAQs
No. As an independent HeatShield service provider, we perform repairs and maintenance that preserve manufacturer warranty coverage when OEM parts and proper procedures are used. We document both. If your warranty claim requires proof of professional service, your photo record and written invoice from us satisfy it.
Most common HeatShield burner assemblies, collars, and refractory panels arrive within 5-7 business days through our Haven buying network. Discontinued series may take 10-14 days if we source compatible replacements from Gelco or Olympia Chimney. We never start work until parts are in hand and you’ve approved the written price.
Most HeatShield fireboxes and components are repairable if the steel frame or refractory shell is structurally sound. We camera and photograph to show you exactly what’s damaged - a cracked panel versus a rusted-out firebox floor are very different costs. When replacement is genuinely safer or more economical, we say so plainly and show you why on camera.
NFPA 211 recommends annual inspection for all solid-fuel systems, including HeatShield wood-burning fireplaces. In Framingham, where homeowners often burn local hardwoods that run higher moisture content, we find Class II creosote buildup accelerates after 12-18 months. Gas HeatShield units benefit from annual burner and valve inspection to catch corrosion before it affects combustion. Call (508) 850-0489 to schedule - estimates are free.
Delayed service on a HeatShield gas unit risks burner port corrosion, delayed ignition from dirty pilot assemblies, and elevated carbon monoxide from incomplete combustion. These are real hazards, not scare tactics - we measure CO in ppm during every service and show you the reading. If your unit is running clean, we’ll tell you that too. Call (508) 850-0489 for an inspection and exact quote.
