We provide independent HeatShield service across Jonesborough’s 37659 ZIP code — the one thing that sets our work apart here is our experience with the unlined multi-flue masonry chimneys that dominate Tennessee’s oldest town.

Why Jonesborough Residents Choose Us for HeatShield Service
We’ve completed over 200 HeatShield installations across the Tri-Cities region, and a disproportionate share of those have been in Jonesborough’s historic core. That’s not coincidence — it’s pattern recognition. After eleven years of chimney-only work, we know what walks through the door when a homeowner on Cherokee Street calls about smoke backing up or water staining the firebox.
Matthew Gonzalez grew up near the Nolichucky River corridor and took his early trade coursework at Walters State Community College in Morristown. He learned combustion and venting fundamentals there, then spent years on roofs where classroom theory meets crumbling lime mortar and flues that don’t appear on any modern diagram. He runs every job himself — no subcontractors, no apprentices working unsupervised. His inspection reports are blunt and detailed because he’s the one who’ll be doing the repair if problems turn up.
We stock genuine HeatShield materials: Cerfractory Foam, Thermix Stainless Steel Liner, ULV Sealant, and Pre-Formed Molded Crowns. We’re independently certified by the Chimney Safety Institute of America and factory-trained on HeatShield’s patented systems, though we are not authorized dealers or partners of HeatShield. For caps that need custom fit on non-standard historic chimneys, we source honest aftermarket options from DuraFlex. When you call us, you’re getting the owner’s hands on your chimney, not a dispatcher sending whoever’s available.
Common HeatShield Chimney Cleaning Problems We Solve in Jonesborough
- Cracked or spalled crown where HeatShield crown coating was applied over unaddressed moisture issues. Jonesborough sits at roughly 1,600 feet in the Appalachian foothills, running colder than the Tennessee Valley floor with repeated hard freeze-thaw cycles each winter. Moisture trapped beneath a crown coating expands, pops the surface, and accelerates failure. We strip failed coatings, repoint first, then apply HeatShield Pre-Formed Molded Crown or ULV Sealant on sound substrate.
- Incomplete seal at flue transitions when HeatShield Cerfractory Foam was installed without proper damper removal. Historic homes on Main Street and Cherokee Street often have ornate original damper assemblies that previous sweeps left in place to avoid damage. Foam sprayed around them leaves gaps. We remove dampers carefully, install the full liner system, then reinstall or fabricate compatible replacements.
- Delamination of stainless steel liners in multi-flue setups where the Thermix liner was not properly supported at offsets. Jonesborough’s irregular historic flues — built for both fireplaces and wood/coal cooking stoves — create angles and offsets that standard liner kits can’t navigate. We field-fabricate support systems and use flexible Thermix sections where rigid pipe would fail.
- Failed mortar joints at the termination where HeatShield sealant was used without prior repointing. We’ve seen this repeatedly on Main Street chimneys: sealant slathered over open joints, trapping water against deteriorated lime mortar. The efflorescence shows up months later. We grind out failed joints, repoint with compatible mortar, then seal.
- Smoke leakage between adjacent flues in unlined multi-flue chimneys. Common in pre-1900 Jonesborough homes where original clay liners were never installed or have collapsed. Our Level 2 inspection with video scan locates the breach; Cerfractory Foam creates a continuous new flue surface that seals gaps between flues.
HeatShield Service in Jonesborough: What Local Conditions Mean for Your Equipment
Last fall, we inspected a Greek Revival home on Main Street built in 1820. The homeowner had complained of smoke backing up into the parlor during a test burn. Using a Level 2 inspection, we discovered an unlined flue with a collapsed clay tile liner about 12 feet down. We installed a HeatShield Cerfractory Foam liner, which conformed to the original irregular flue shape and sealed the gap in the adjacent flue. The job took two days, but the homeowner now has a functioning, code-compliant chimney that looks original.
That job illustrates why Jonesborough is different. The historic district has over 35 properties listed on the National Register, and many still rely on unlined multi-flue chimneys built before 1900. These chimneys often require a custom HeatShield liner installation that accommodates the original firebox geometry — a process that demands precise measurement and on-site fabrication. Routine in our Jonesborough service calls. Rare elsewhere. The National Storytelling Festival each October draws tens of thousands of visitors and functionally marks the first weekend many homeowners light their fireplaces for the year. Local sweeps know late September is peak pre-season rush, and historic-district chimneys inspected then frequently reveal unlined flues where previous owners simply never addressed the absence of a modern liner. I’d rather tell you something you don’t want to hear now than have you call me after a chimney fire.
HeatShield Models & Products We Service in Jonesborough
We work with the full HeatShield product line and stock the core materials for fast turnaround on Jonesborough jobs:
- HeatShield Cerfractory Foam — Our primary relining solution for unlined historic masonry. Ceramic-fiber technology withstands temperatures to 3,000°F and conforms to irregular flue shapes that rigid liners can’t follow.
- HeatShield Thermix Stainless Steel Liner — Used where structural integrity is compromised beyond what foam can address, or where gas appliance venting requires metal. We field-fabricate offsets for Jonesborough’s non-standard flues.
- HeatShield ULV (Ultra Low VOC) Sealant — For crown repairs and minor masonry sealing where full crown replacement isn’t warranted. Low odor, suitable for occupied historic homes with sensitive finishes.
- HeatShield Pre-Formed Molded Crown — Custom-fit crown restoration when the original concrete or stone crown has failed. We measure on-site for chimneys that don’t match any standard dimension.
We exclusively use genuine HeatShield repair materials for relining and crown restoration because their ceramic-fiber technology is unmatched for historic masonry. However, we recommend full rebuilds over patchwork when mortar joints are completely deteriorated — a common scenario in Jonesborough’s 200-year-old chimneys. For caps, we source honest aftermarket options from DuraFlex when custom fit is needed, since historic chimney dimensions rarely match catalog stock.
HeatShield Service Pricing in Jonesborough
HeatShield work in Jonesborough varies with chimney condition, access, and the degree of custom fitting required for historic geometry. Here’s what we typically see:
| Service | Price Range |
|---|---|
| Level 2 Inspection with video scan | $250–$400 |
| HeatShield Cerfractory Foam relining (single flue, standard access) | $1,800–$2,800 |
| HeatShield Cerfractory Foam relining (multi-flue or custom fit, historic district) | $2,400–$4,500 |
| HeatShield Thermix Stainless Steel Liner installation | $2,200–$3,800 |
| Crown repair with HeatShield ULV Sealant or Pre-Formed Molded Crown | $650–$1,400 |
| Chimney rebuilding (partial or full, when relining isn’t viable) | $3,500–$8,000+ |
What drives cost: flue count and configuration, degree of mortar deterioration, roof access difficulty, and whether previous repairs need removal before proper work can begin. Historic chimneys with ornate corbelling or steep roof pitches add labor. Our free estimate includes the full Level 2 inspection, written report with video documentation, and itemized repair options — no obligation.

FAQs — HeatShield Chimney Cleaning in Jonesborough
Yes — HeatShield Cerfractory Foam is specifically designed to conform to irregular flue shapes, including the curved and offset flues we regularly encounter in Jonesborough’s pre-1900 chimneys. The foam is sprayed in layers and smoothed to create a continuous, round flue surface regardless of original geometry. For severe offsets, we may combine foam with flexible Thermix sections. Call (888) 799-1933 for an inspection and we’ll show you exactly what your flue looks like inside.
No — HeatShield Cerfractory Foam is an interior repair that doesn’t alter exterior appearance. The National Register designation focuses on visible, character-defining features; an invisible flue liner doesn’t trigger review. We’ve worked on multiple listed properties in Jonesborough’s historic district without preservation complications. We document our work with photos for your records, which can actually support future preservation applications by showing responsible maintenance.
Jonesborough’s 1,600-foot elevation and hard winter freeze-thaw cycles accelerate spalling and mortar joint erosion on exposed brick chimneys. HeatShield crown repairs fail quickly if applied over moisture-saturated or deteriorated substrate. We always inspect and repoint before applying HeatShield ULV Sealant or Pre-Formed Molded Crown, and we verify the chimney is dry. This prep work adds time but prevents the callbacks we see from jobs where sealant was slapped over wet, crumbling masonry.
Jonesborough’s historic chimneys were built before standardization existed. Flue dimensions, crown overhangs, and overall chimney profiles vary significantly — a catalog cap either won’t fit or will leave gaps that admit water and animals. We measure on-site and source custom-fit caps from DuraFlex or fabricate solutions when needed. A proper cap protects your HeatShield liner investment and prevents the moisture intrusion that destroys historic masonry from the top down. Call (888) 799-1933 and we’ll measure yours during the free estimate.
Yes, though the existing clay tile condition determines our approach. If tiles are cracked, displaced, or partially collapsed — common in Jonesborough chimneys where previous owners installed low-quality liners — we remove debris and install HeatShield Cerfractory Foam directly against the masonry, creating a new flue surface. If tiles are sound but joints are open, we may use foam to seal the system. Our Level 2 inspection with video scan shows exactly what we’re working with before we recommend a specific repair. Call (888) 799-1933 to schedule; estimates are free.
