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 Lynchburg: What to Know First
We provide independent HeatShield chimney liner and rebuild service in Lynchburg, with most inspections booked within a few days and liner replacements typically completed in a single visit. Our HeatShield jobs run from around $2,800 for a straightforward Cerfractory foam resurfacing up to $7,500 or more for a full stainless steel liner replacement with partial rebuild. We are not affiliated with or authorized by HeatShield - we are an independent service provider who has worked on enough of their systems across central Virginia to know where they hold up and where they don’t.
This page is for Lynchburg homeowners who know they’ve got a HeatShield liner or suspect they do, and need someone to tell them straight whether it can be repaired or needs to come out. If you’re seeing flakes in the firebox, smelling smoke in rooms you shouldn’t, or staring at an inspection report that mentions “spalling” or “gaps,” call us at (540) 328-6986. We’ll look at what you have and tell you what it actually means.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam Resurfacing (CFR) - thermal shock cracking in Lynchburg’s freeze-thaw cycles. The CFR system is sprayed directly onto the existing clay liner to create a new, smooth surface. In Lynchburg, we see it fail where water has been getting in through a cracked crown or missing cap, then freezing. The foam layer separates from the clay beneath in thin sheets. We strip the failed foam, repair the water entry point first, then resurface with new Cerfractory material or recommend a full stainless replacement if the clay behind it is too far gone.
- HeatShield UL Listed Stainless Steel Liners - weld-seam corrosion from acidic condensation. The 316Ti alloy resists most flue gases, but we’ve found the lower-flex models installed in the early 2010s can develop pinhole leaks at the longitudinal weld seam, especially in chimneys serving ventless gas logs that produce more moisture. We camera-inspect the full length, mark the leak points, and either section-replace with new HeatShield-compatible 316Ti or switch to a DuraFlex liner if the whole run is questionable.
- Joint Repair System (JRS) - mortar joint gaps reopening after 5-7 years. JRS fills the mortar joints between clay flue tiles with a specialized refractory compound. It works well when the tiles themselves are sound, but in older Lynchburg homes, especially the pre-1940s stock along Rivermont Avenue and Diamond Hill, the clay tiles shift as the chimney settles. The compound cracks at the joint. We remove the JRS material, assess whether the tiles can be stabilized, and either reapply with modified anchoring or move to a full liner replacement.
- HeatShield Pro-Form Flexible Liners - ovalization in offset chimneys. The Pro-Form line is designed to navigate offsets, but in chimneys with multiple bends common in the bungalow-style homes around Boonsboro, the liner can flatten slightly at the elbows. This reduces draft and accelerates creosote buildup. We measure the cross-section with a borescope, and if ovalization exceeds 15%, we replace with a DuraFlex smooth-wall liner that holds its shape better in tight offsets.
- CrownSeal top-coat systems - delamination from UV exposure on south-facing chimneys. Not a liner failure per se, but CrownSeal is often paired with HeatShield liner jobs, and we’ve seen it peel where Lynchburg’s summer sun hits the crown directly. Water then enters, undermines the liner system from above. We grind off the failed coating, rebuild the crown with proper slope and drip edge, then apply a new UV-stable seal or recommend a poured concrete crown for permanence.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We book a Level-2 camera inspection, usually within a week in peak season, sooner if you’re between burns.
- 2
Inspection with documentation. Our technician runs a camera the full length of the flue, records video, and photographs every defect. You get the photos and a plain-English verdict - no jargon, no vague warnings. Russell Haines reviews every HeatShield assessment personally; he’s caught liner damage that other eyes have missed, particularly in the older masonry around Daniels Hill where chimneys have been modified more than once.
- 3
Parts decision: OEM HeatShield, compatible aftermarket, or alternative brand. If your system is under warranty, we source genuine HeatShield materials to protect that coverage. If the warranty has expired, we may recommend Gelco or Olympia Chimney components that meet the same UL 1777 standard at lower cost, or a DuraFlex liner if the application calls for better flexibility. We explain the trade-off and let you decide.
- 4
The repair or rebuild. Our background-checked, uniformed technicians arrive with the materials in hand. Most liner replacements and partial rebuilds finish in one day. We protect your floors, work clean, and don’t leave until the job is right.
- 5
Post-repair testing and documentation. We run a smoke test or draft gauge check to verify proper venting. You get a written report with photos of the completed work, the 90-Day Done Right Promise in writing, and our permanent 5% Senior and Veteran discount applied if it applies to you.
What HeatShield Chimney Liner & Rebuild Costs in Lynchburg
These are real numbers from jobs we’ve done in Lynchburg and the surrounding counties. Your exact price depends on what the camera shows, the height of your chimney, and whether we can access the roof safely without specialized rigging.
- Cerfractory foam resurfacing (single flue, accessible crown): $2,800-$4,200
- Joint Repair System reapplication with tile stabilization: $1,900-$3,400
- Stainless steel liner replacement, straight run, standard height: $4,500-$6,200
- Stainless steel liner with offset navigation or partial rebuild: $5,800-$7,500
- Full chimney rebuild with new liner (severe structural failure): $8,500-$14,000
What moves the price: chimney height above 25 feet, multiple flues, hidden water damage to the smoke chamber, and whether the existing liner can be extracted or has to be demolished in place.

FAQs
No, provided the work is done with genuine HeatShield materials by a qualified technician. As an independent HeatShield service provider, we source OEM components when your warranty is still active. If the warranty has expired, we will explain compatible alternatives that meet the same safety standards. Call (540) 328-6986 and we can check your installation date against HeatShield’s coverage terms.
The camera tells the story. Surface cracks in a CFR coating often qualify for resurfacing. If the underlying clay tile is crumbling, or if a stainless liner shows multiple pinholes or weld-seam corrosion, replacement is the safer path. We show you the footage and explain which category you’re in. Call for a free inspection - estimates cost nothing.
Most HeatShield components remain available, though some early Pro-Form flex sizes have been discontinued. We maintain relationships with multiple distributors and can often source compatible fittings. When OEM is not practical, we specify DuraFlex or Gelco alternatives that meet the same UL 1777 listing. We never leave you guessing about what went in your chimney.
Most resurfacing and joint repair jobs finish in four to six hours. A full stainless steel liner replacement typically takes one full day; a partial rebuild with liner may extend to two days if the masonry needs cure time. We schedule the work when you can be home, and we don’t disappear mid-job.
A compromised liner allows heat, sparks, and combustion gases to reach the framing and masonry surrounding your flue. In Lynchburg’s older homes with balloon framing, that risk is not theoretical. Carbon monoxide can seep into living spaces through gaps you cannot see. The repair cost does not go down with waiting - water and freeze-thaw cycles keep working whether you address them or not. Call (540) 328-6986 for a free estimate and camera inspection.
