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 separates from the flue wall in the smoke chamber. The foam application depends on proper surface prep and cure conditions. In Kennesaw’s humid shoulder seasons, we’ve found applications done during high-humidity windows that never fully bonded. We strip the failed section, re-prep with mechanical abrasion, and reapply only when the flue temperature and ambient humidity read in spec. Corrine Halstead won’t sign off on a Cerfractory repair without a hardness test pin reading that matches the manufacturer’s published cure table.
- HeatShield UL Listing requires compatible components; mixing series voids coverage. The HeatShield Joint Repair system and the CeCure Sleeve Relining system use different bonding agents and expansion coefficients. We’ve seen Kennesaw homeowners with a CeCure-sleeved flue who had a general handyman patch a joint with Joint Repair compound - the mismatch cracked within two burn seasons. We source the correct HeatShield-series material through our Haven buying network and document the batch number on every job.
- Gas fireplace inserts with HeatShield-compatible flue collars develop CO leakage at the seal. The collar gasket compresses over thermal cycles, especially in Kennesaw homes where the insert sees heavy weekend use and sits cold all week. We don’t just replace the gasket; we check the collar squareness with a feeler gauge and resurface the mating face if it’s warped more than 1/16 inch.
- Firebox panels in HeatShield-equipped systems spall from the inside out when the liner is undersized. The flue draws too slowly, combustion gases linger, and the refractory panels take the thermal abuse. In the older colonials near Kennesaw Mountain, we regularly find 6-inch round liners serving a firebox that needs an 8-inch oval or square. We measure the firebox opening and calculate the required flue area per NFPA 211 before quoting any panel replacement.
- Damper assemblies on HeatShield wood burning fireplaces seize from creosote glazing above the throat. The stainless damper frame tolerances are tight, and Class III creosote - the baked-on, tar-like stuff - wedges in the pivot. We remove the damper, ultrasonically clean it off-site, and address the root cause: the flue liner condition that let the creosote form there in the first place. A new damper without liner repair buys you two seasons, maybe three.
Our HeatShield Fireplace Services Process

- 1
Call and schedule. A live person answers, 24/7. We ask the HeatShield product series if you know it, the fuel type, and what you’re seeing. We book an NFPA 211 Level 2 inspection with camera scan.
- 2
Inspection and documentation. Our tech runs a camera from the firebox to the crown, captures stills and video, and records liner condition, creosote class, and any spalling or joint gaps. You see the footage on-site.
- 3
Written price and scope. Before any repair, you get a written price, written scope, and written warranty - Haven Standard Clause 1. If we recommend OEM HeatShield parts, we explain the parts nuance; if a quality aftermarket option from DuraFlex or Gelco meets the spec for less, we explain that too.
- 4
Repair with verification. We complete the work, test-fire the system, and capture post-repair camera footage. Hardness tests or pressure tests are logged per the repair type.
- 5
Done Right Promise and record. The 365-Day Done Right Promise applies. Your documented photo record, including batch numbers and test readings, is archived under Haven Standard Clause 4 - same practice we’ve run since 2009.

Our background-checked, uniformed technicians carry license information on every page and text when they’re en route.

And our Free Second Opinion on any written estimate lets you bring us a competitor’s HeatShield quote and know exactly where the scope or materials differ.
FAQs
No. HeatShield warranties cover product defects and proper application, not who performs the service. We document batch numbers and application conditions so any legitimate warranty claim has the paperwork it needs. If you’re unsure about your warranty status, call (678) 535-2204 and we’ll review it with you during your free estimate.
Most HeatShield materials ship to us within 5-7 business days through our Haven buying network. For urgent situations, we stock compatible refractory and gasket materials from DuraFlex, Gelco, and Olympia Chimney that meet or exceed the spec - we’ll tell you exactly what’s OEM and what’s equivalent before you decide.
Most HeatShield systems we see in Kennesaw are repairable. Full replacement becomes the honest recommendation only when the flue liner has multiple joint failures, the firebox is structurally compromised, or the cost of stacked repairs approaches 70% of replacement. We show you the camera footage and run the numbers both ways - no pressure either direction.
We treat CO leaks as same-day priority. Call (678) 535-2204 immediately, ventilate the space, and do not operate the unit. We’ll inspect, identify the source - often a collar seal, draft inducer, or liner breach - and give you a written repair price before any work begins. If the repair requires parts we don’t stock, we’ll secure the unit safely and schedule the fix as soon as materials arrive.
Joint Repair is a cerfractory foam resurfacing for smoke chambers and flue walls with minor damage - faster, less invasive, lower cost. CeCure is a sleeve system for flues with more extensive deterioration or sizing issues. We determine which applies by measuring liner thickness, mapping damage with the camera, and checking the flue diameter against the firebox opening. The wrong choice fails early; we don’t guess.
