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 flue liner delamination in unlined Boston chimneys. The original HeatShield Cerfractory system is a cast-in-place liner, and in Boston’s freeze-thaw cycle, hairline cracks in the mortar bed behind it let moisture work between the ceramic and the masonry. You’ll see flaking or soft spots when we run the camera down. The fix is a proper prep of the flue surface and a new HeatShield application, or a DuraFlex stainless liner if the flue’s too far gone.
- HeatShield firebox refractory panels cracking at the mortar joints. On HeatShield wood-burning fireplaces, the refractory panels take the direct brunt of every fire. We see cracks radiating from the corners where the firebox meets the smoke chamber - that’s a symptom of the firebox shifting slightly with the house. We replace the panels with OEM HeatShield refractory or a matched aftermarket panel, re-point the joints, and photograph the finished work.
- HeatShield smoke chamber parging failing on older Boston triple-deckers. A lot of Dorchester and Southie triple-deckers had HeatShield parging applied to the smoke chamber decades ago, and we see it spalling - flaking away in chunks - which creates a rough surface that catches creosote. We remove the loose parging, re-apply a smooth refractory coat, and verify the draft with a smoke test before we leave.
- HeatShield damper frames warping from heat cycling. On HeatShield fireplaces with cast-iron dampers, the frame around the damper blade can warp after enough seasons of hot fires followed by cold Boston winters. You’ll notice the damper won’t fully close, or it sticks halfway. We replace the damper assembly with a properly sized unit and test the closure with a flashlight from the firebox.
- HeatShield gas fireplace burner ports clogging in high-soot Boston neighborhoods. HeatShield gas log sets and gas fireplace burners collect soot faster in Boston’s older housing stock, especially near busy arteries. The symptom is uneven flame or yellow tipping. We pull the burner, clear the ports, check the thermocouple and thermopile, and log the gas pressure readings in your service record.
Our HeatShield Fireplace Services Process

- 1
Call and book a time. A live person answers at (857) 567-8887, 24/7. We schedule the visit and assign a named tech. You get a text when they’re on the way.
- 2
Camera inspection, HeatShield-specific. The tech runs a camera through the flue and firebox, documenting everything. Clause 4 of the Haven Standard requires a photo record on every job, and that’s been our practice since 2009.
- 3
Written scope and price. Before any repair, you get a written description of what’s wrong, what parts are needed, and an exact price. Not an estimate range - a written number.
- 4
The repair itself. We use OEM HeatShield parts where the warranty matters, and quality aftermarket parts where it doesn’t. We’ll tell you which is which and why. If a DuraFlex or Gelco component is a better fit for the job, we’ll say so.
- 5
Test and document. Every repair gets a draft test or a gas leak check, depending on the system. You leave with photos, readings, and the written warranty on the work.
- 6
365-Day Done Right Promise. If something’s not right within a year, we make it right. It’s stamped on your job record.

AfterWhat HeatShield Fireplace Services Costs in Boston
Here’s the honest math for HeatShield work in Boston, based on what we’ve done across the city:
| Job | Typical Range |
|---|---|
| HeatShield fireplace inspection with camera | $129-$189 |
| Firebox refractory panel replacement (per panel) | $220-$380 |
| Damper replacement, cast-iron | $310-$520 |
| Smoke chamber re-parging with HeatShield refractory | $900-$1,600 |
| Full HeatShield flue liner replacement (2-story) | $2,400-$4,200 |
What moves the price is access. A fireplace on the third floor of a Dorchester triple-decker with a steep pitch costs more than a first-floor firebox in a Newton ranch. Parts availability matters too - HeatShield refractory ships quick, but some gas logs and burner assemblies take longer. Call (857) 567-8887 and we’ll give you a written estimate before you spend a dollar. Free Second Opinion on any competitor’s written quote, always.
Why Boston Homeowners Call Level Two Chimney Boston for HeatShield Work

We’re not a HeatShield dealer and we don’t pretend to be. We’re the company that’s been running a camera down Boston chimneys since 2009 and handing homeowners a written price before any work starts. 38,000+ chimneys inspected and cleaned, every one with a photo record. The camera doesn’t guess. Neither do we.
Our techs know HeatShield failure patterns because we’ve fixed enough of them to see what repeats. But they also know when a HeatShield repair isn’t the right call - and when a DuraFlex stainless liner or a Gelco firebox panel will serve you better. That’s the difference between a parts-swapper and a real diagnosis.
Background-checked, uniformed techs. License number on the page. A named tech assigned to your job. And if it’s not done right, the 365-Day Done Right Promise says we make it right. Written, not spoken.
FAQs
No, not when it’s done correctly. Independent fireplace service does not void a HeatShield warranty. What voids it is improper installation or using the wrong parts. We use OEM HeatShield components when the warranty is a factor, and we document every part and reading so you have a record if you ever need to file a claim.
Most HeatShield fireplace repairs are booked within 3-5 business days in Boston, and the repair itself is usually done in one visit. Exceptions are parts that need to ship - some HeatShield gas logs and burner assemblies add a week or two. Call (857) 567-8887 and we’ll tell you the timeline after the camera inspection, in writing.
You’ll know because we show you the camera footage. If the liner has hairline cracking but no flaking or exposed masonry, it can often wait another season. If we see delamination or spalling, that’s a repair that shouldn’t wait. We’ll give you a written assessment with photos either way, and we’ll tell you plainly when something can safely wait until next year.
Both, plus inserts and fireplace conversions. Our Boston techs service HeatShield gas log sets, gas burner assemblies, and full gas fireplace inserts, along with wood-burning HeatShield fireplaces. If you’re converting from wood to gas or vice versa, we’ll quote it in writing and tell you which HeatShield components carry over.
A full NFPA 211 Level 2 inspection: camera through the flue, firebox condition, damper function, smoke chamber, and draft or gas readings depending on the system. You get every photo and reading in a written report before any repair is even discussed. Clause 4 of the Haven Standard - the photo record - has been our default since 2009.
