Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Upper Nazareth isn’t like the boroughs around it. The township’s housing stock is newer, built in waves through the 1990s and 2000s, and most of those homes came with factory-built zero-clearance fireplaces rather than traditional masonry chimneys. That means the problems we find here are different from what we’d see in a 1920s Nazareth rowhome or a Bangor farmhouse. A chimney that looks fine from the street can already have a rusted chase cover pouring water into the firebox. We’ve learned the hard way that “newer” doesn’t mean “maintenance-free” in Upper Nazareth’s climate.
Why Hearthstone Chimney Co. Is Upper Nazareth’s Preferred Chimney Liner & Rebuild Company
We’ve worked in Upper Nazareth long enough to know which subdivision was built when, which builders used which prefab fireplace brands, and what fails first on each. The Steeplechase homes off Georgetown Road, the developments along Daniels Road, the properties tucked near the township’s rural edges toward Bushkill Township - we’ve rebuilt fireboxes and replaced chase covers in all of them. Our technicians carry the factory-spec refractory panels and gaskets that match the most common units installed here during the build-out years.
Our customers in Upper Nazareth tell us the same thing: they want to see the problem before they pay to fix it. Every Chimney Liner & Rebuild inspection we do here includes a Level-2 camera inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics. If the liner’s cracked, we’ll show you the crack. If the chase cover’s just starting to rust and can wait a season, we’ll say so.
Calls are answered by a live person, 24 hours a day, 7 days a week. Our background-checked, uniformed technicians complete most jobs in a single visit. And every repair is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
Our Chimney Liner & Rebuild Services in Upper Nazareth
Stainless Steel Liner Installation
A stainless steel liner is the right fix when your prefab fireplace’s original factory liner has cracked or corroded, or when an older masonry chimney in Upper Nazareth needs a complete flue restoration. We install DuraFlex and Olympia Chimney stainless liners sized precisely to your unit’s BTU rating and draft requirements. In Upper Nazareth’s newer homes, this often means retrofitting a liner into a factory-built chase that was never designed for one - a job that requires knowing the manufacturer’s clearances and keeping the chase’s ventilation pattern intact. Done wrong, you’ll get overheating or poor draft. Done right, you’ll have a system that vents safely for decades.

Flexible Liner Replacement
Flexible liners solve the offset problems common in prefab fireplace chases where rigid pipe won’t navigate factory-built bends. We use DuraFlex flexible stainless products for Upper Nazareth homes where the original venting has failed or where a previous installer used the wrong material. The freeze-thaw cycling near Blue Mountain accelerates corrosion in lower-grade flex liners; we’ve pulled out plenty of prematurely failed products that weren’t rated for this climate. We match the alloy grade to your appliance type - gas, pellet, or wood - and we document the installation with photos for your records.

Liner Replacement for Factory-Built Units
This is where Upper Nazareth’s housing stock really matters. Most township homes built from 1992 to 2008 have prefab fireplaces with manufacturer-specific venting systems, not generic clay flues. When the refractory panels crack, the gaskets fail, or the chase cover leaks water onto the firebox, “liner replacement” often means sourcing factory-authorized components and rebuilding the unit to spec. We stock and install HeatShield refractory panel systems and factory-matched gaskets for the most common brands found in local subdivisions. We also replace the chase covers with stainless or copper versions that won’t rust through in five years like the original galvanized steel.

Partial Rebuild of Prefab Firebox and Chase
When water intrusion has gone beyond surface rust, a partial rebuild can save the unit. We recently rebuilt the firebox and replaced the failed chase cover on a 2001-built home in the Steeplechase development off Georgetown Road. The galvanized cover had rusted through at the seams from years of freeze-thaw cycling near Blue Mountain, allowing water to rot the refractory panels and warp the damper. We swapped in a stainless cover, installed new factory-spec refractory panels, gaskets, and a stainless steel liner from DuraFlex to restore safe draft, and the homeowner avoided a full factory-built unit replacement. That’s the kind of outcome we’re after - fix what’s actually broken, don’t replace what isn’t.

Trusted Brands We Service in Upper Nazareth
We don’t use builder-grade substitutes. Our Upper Nazareth trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - the brands that factory engineers specify and that hold up in real Pennsylvania winters. Because we stock common refractory panels, gaskets, and chase cover sizes for the most prevalent prefab units in township subdivisions, we can often complete a repair same-visit without waiting on a parts order. For less common factory-built systems, we source directly from the manufacturer and coordinate installation once the components arrive. No improvisation, no “close enough.” The part either matches the spec or we don’t install it.
Common Chimney Liner & Rebuild Problems We See in Upper Nazareth Homes
- Rusted-through chase covers on late-1990s and early-2000s prefab fireplaces. The galvanized sheet-metal covers installed during the township’s build-out years fail at seams and fastener points after 15-20 years of Upper Nazareth’s aggressive freeze-thaw cycles. Water leaks directly onto the firebox below, destroying refractory panels and rusting dampers before homeowners notice any interior symptom.
- Cracked refractory panels from thermal cycling. Factory-built fireplace refractory panels crack around the 20-year mark from repeated heating and cooling. In Upper Nazareth’s tract subdivisions, many homeowners never schedule annual Level 2 inspections, so the damage is usually discovered only after a chase cap failure or a visible water stain on the ceiling - by which time the firebox framing may also be compromised.
- Improperly converted older masonry chimneys on rural edges. The township’s remaining farmhouse-era properties often have large clay-tile-lined masonry chimneys originally built for coal or wood furnaces. Many were uncapped for years or converted to gas without proper liner sizing. The same freeze-thaw cycling that damages newer chase covers spalls brick and cracks crowns on these older structures, and their clay liners frequently fail at mortar joints in ways a standard sweep won’t catch.
- Failed factory gaskets creating draft and CO hazards. The high-temperature gaskets sealing the glass doors and combustion chambers of prefab units degrade over time. In Upper Nazareth’s tightly built subdivision homes, even a small gasket leak can spill combustion gases into living spaces - a risk that camera inspection catches before it becomes dangerous.

What moves the number? Chase height and roof access affect labor. The specific prefab manufacturer determines parts availability and cost. And whether we’re working from a clean inspection or cleaning up after years of deferred maintenance - we’ve seen fireboxes in Upper Nazareth that needed three times the labor because the chase cover had been leaking unnoticed for four seasons. We give you a fixed price before we start. The number on the estimate is the number on the invoice. Estimates are free, and we don’t charge to look.

FAQs - Chimney Liner & Rebuild in Upper Nazareth
A 2003 prefab fireplace in Upper Nazareth is now 20-22 years old, squarely in the failure window for factory-built components. The galvanized chase cover is likely rusting at seams. The refractory panels have cycled through thousands of heating and cooling episodes. The original gaskets are brittle. These units were built to a 15-25 year service life with maintenance; without it, they fail on schedule. Call (610) 609-7634 for a camera inspection - we’ll show you exactly what’s happening inside.
No. Steeplechase and similar Upper Nazareth subdivisions have factory-built zero-clearance fireplaces with metal chases; older Nazareth proper has predominantly masonry chimneys with clay flue liners. The failure modes are completely different. We replace chase covers and refractory panels in Upper Nazareth subdivisions, while across the borough line we’re more often repointing mortar joints and installing stainless liners in masonry flues. The tools, materials, and expertise don’t fully transfer. That’s why local experience matters here.
It means water is already getting through, and the firebox below is taking damage you can’t see from the living room. Rust stains on a galvanized chase cover are the first visible sign of seam failure. In Upper Nazareth’s climate, once the rust shows, the cover is typically 12-18 months from leaking directly into the chase framing. We replace these with stainless or copper covers that won’t rust through. Call for an inspection - the cover itself is a quick fix; the firebox damage it causes is not.
Every year, per NFPA 211, regardless of age. For Upper Nazareth’s 1990s-2000s prefab units, we strongly recommend a Level 2 inspection with camera - not just a sweep - because the critical failures (chase cover rust, refractory panel cracking, gasket degradation) happen in enclosed spaces a basic visual won’t reach. Annual inspection catches chase cover rust at replacement cost rather than firebox rebuild cost. The $89 Seasonal Tune-Up we offer includes this level of scrutiny.
In most cases, we can rebuild the damaged section and restore the unit to factory spec. Partial rebuild - new refractory panels, gaskets, chase cover, and liner if needed - is our standard approach in Upper Nazareth. Full unit replacement is only necessary when the firebox framing or chase structure itself has been compromised by long-term water intrusion. Our camera inspection shows you which category you’re in before any commitment. For a free assessment, call (610) 609-7634.
Ready to see what’s actually going on inside your chimney? We’ll inspect it, photograph it, explain it in plain English, and give you a fixed price. No pressure, no surprises on the bill. Call Hearthstone Chimney Co. at (610) 609-7634 for your free estimate.
