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.

AfterGelco Chimney Liner & Rebuild in Lynchburg: What to Know First
We provide independent Gelco chimney liner and rebuild service across Lynchburg, with most inspections completed within a few days of your call and liner replacements typically scheduled within one to two weeks. Gelco stainless and flexible liners run $2,200-$4,800 installed in this market, depending on flue count and access, and we quote that number upfront before any work begins. This page is for homeowners who know they’ve got Gelco components in their chimney system and need straight answers about whether to repair, replace, or rebuild. If you’re seeing rust flakes in your firebox, smelling smoke in upstairs rooms, or staring at a contractor’s estimate you don’t fully trust, call us at (540) 328-6986. We’ll walk you through what you actually have and what it actually needs.
How Gelco Products Fail - and How We Fix Them
- Gelco UltraPro rigid stainless liners develop weld-seam separation near the top flue section after 12-18 years of Lynchburg’s freeze-thaw cycling. The 304-grade body holds up, but the longitudinal seam at the collar joint opens from thermal shock during shoulder-season burns. We cut back to sound metal, fabricate a custom transition, and pressure-test the new joint before we leave.
- Gelco flexible multi-flue liners sag between support points in taller Colonial Revival chimneys common in Rivermont and Diamond Hill. The corrugated wall fatigues at the low point, collecting acidic condensate that pinholes from the inside out. We add a mid-span support bracket and sleeve the damaged section with DuraFlex Pro rather than replacing the entire run.
- Gelco pre-fab chimney chase pans on factory-built systems crack at the corner welds after repeated expansion from summer humidity followed by dry winter heating. Water runs down the chase and pools behind the liner, accelerating exterior rust. We replace with a copper or stainless pan, never galvanized, and seal with high-temp silicone rated to 500°F.
- Gelco liner top plates and storm collars loosen as the original hardware settles. The clamp-style fasteners Gelco used through the mid-2000s back out from vibration during wind events on exposed ridges around Boonsboro. We upgrade to through-bolted connections with locking washers, which costs more in hardware but eliminates callbacks.
- Gelco smooth-wall rigid liners in oil-to-gas conversions often run undersized for the new appliance’s lower flue temperature, causing chronic downdraft and soot staining on the hearth. The liner itself isn’t failed, but it’s mismatched. We resize per NFPA 211 using Olympia Chimney’s diameter charts and document the before-and-after draft readings for your records.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask what you’re seeing, what appliance you’re running, and when the Gelco liner was installed if you know. We’ll pencil you in for a Level-2 camera inspection.
- 2
Inspection and documentation. Our tech runs a chimney camera from top to bottom, records video, and photographs every joint, support, and termination. You get the photos and a plain-English verdict. “Tell me what you’re seeing, and I’ll tell you what it actually means.”
- 3
Parts decision. If Gelco OEM is available and cost-effective, we order it. If lead time stretches past burning season or the part is obsolete, we specify quality aftermarket from DuraFlex or HeatShield that matches or exceeds Gelco’s original spec. We explain the trade-off and you decide.
- 4
Repair or rebuild. Background-checked, uniformed technicians complete most Gelco liner replacements and partial rebuilds in a single visit. Full chimney rebuilds take two to three days. We protect your floors, haul away old material, and keep you informed if we find something the inspection didn’t show.
- 5
Testing and sign-off. We pressure-test liner joints, verify draft with a manometer, and run the appliance through a complete burn cycle. You get the test results, the photos, and the 90-Day Done Right Promise in writing.
- 6
Cleanup and follow-up. We leave the work area cleaner than we found it. A week later, we call to confirm everything is performing as expected. If not, we come back. No paperwork, no arguing.

Why Lynchburg Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been answering the phone with a live person for over 42 years, and we’ve learned that Gelco owners in Lynchburg want two things: someone who recognizes what they’ve got, and someone who won’t invent problems to sell a bigger job. Russell Haines built this company on showing up when we say we will, explaining what we found without dressing it up, and not leaving until the job is right. Our technicians carry Gelco, DuraFlex, and HeatShield specifications in their tablets, so the recommendation is based on what fits your system, not what we happen to have on the truck. The 90-Day Done Right Promise covers every liner and rebuild job in writing - if it’s not right, we make it right, no arguing. That’s the Keystone Standard. Done right, and we stand behind it.
FAQs
No. Gelco’s original warranty on materials expired years ago for most Lynchburg installations, and as an independent Gelco service provider, our repairs do not affect any remaining coverage on factory-built components. We document our work with photos and serial numbers in case you need records for your homeowner’s insurance. Call (540) 328-6986 if you’d like us to verify what’s still covered.
Most Gelco liner replacements are completed in a single day. A straightforward flexible liner swap in a ranch-style home near Timberlake takes four to six hours. A rigid liner in a three-story Victorian on Daniels Hill with a steep roof might stretch to eight hours or require a second day for curing if we’re also pouring a new crown. We tell you the timeline before we start, and we stick to it.
We can often match Gelco parts for repairs, but several common components - the pre-2010 clamp-style top plates, certain flexible liner diameters - are now obsolete. When OEM isn’t available, we specify DuraFlex or HeatShield equivalents that exceed Gelco’s original spec and maintain full compatibility. We show you both options and the price difference, and you choose.
If the damage is localized - one separated joint, one sagging section, a cracked storm collar - repair usually makes sense. If we’re finding pinholes every few feet, the support system has failed throughout, or the liner is undersized for your current appliance, replacement is the square deal. Our camera inspection shows you exactly what we’re seeing so you can decide with confidence. Estimates are free - call (540) 328-6986.
A damaged liner lets combustion gases, including carbon monoxide, leak into wall cavities and living spaces. In Lynchburg’s older homes with balloon framing, that migration happens faster than you’d think. A separated liner can also allow creosote to build between the liner and clay tile, creating a hidden fire hazard. We don’t scare-sell, but we don’t soft-pedal real risk either. If the camera shows it’s unsafe, we’ll say so plainly. If it can wait a season, we’ll say that too. Call (540) 328-6986 and we’ll tell you which category you’re in.
