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.
Fast, Reliable Chimney Liner & Rebuild Across Upper Nazareth
A factory-built fireplace in Upper Nazareth typically needs liner replacement or partial rebuild work between years 20 and 30, with most jobs running $1,800-$4,500 and completed in a single visit.

Upper Nazareth’s neighborhoods were built fast and built similar. The colonials and bi-levels off Georgetown Road, Friedensthal Avenue, and the Schoeneck corridor went up in waves from the late 1980s through the 2000s, most with the same prefab fireplace models in metal chases. We know these systems. We’ve replaced their liners, rebuilt their fireboxes, and swapped their rusted chase covers on hundreds of Upper Nazareth homes. When your fireplace is failing, you want someone who recognizes the model before they open the chase.
Why Hearthstone Chimney Co. Is Upper Nazareth’s Preferred Chimney Liner & Rebuild Company
Our reputation in Upper Nazareth was built one cul-de-sac at a time. Homeowners here talk to neighbors, and neighbors compare notes when three houses on the same street develop the exact same cracked refractory panel. We’ve earned that word-of-mouth by showing up when we say, documenting every inspection with photos the homeowner can see, and backing every job with our 90-Day Done Right Promise in writing.
Dispatch and scheduling are coordinated from our Philadelphia office, but our technicians live in and around Northampton County. That means we’re not driving two hours to reach Upper Nazareth. We’re already here. Most liner and rebuild jobs are completed in a single visit because our trucks carry the prefab-specific parts these homes actually need, not generic masonry supplies that won’t fit a zero-clearance chase.
Russell Haines, who leads Hearthstone Chimney Co., set the standard decades ago: a plain-English verdict, a fair price agreed before any work starts, and a guarantee that means something. In Upper Nazareth, where many homeowners have been in their houses for twenty-plus years and intend to stay, that steadiness matters. You don’t want a hard sell. You want the thing done right.
Our Chimney Liner & Rebuild Services in Upper Nazareth
Stainless Steel Liner Installation
A stainless steel liner is the correct replacement for most corroded or glazed prefab flues in Upper Nazareth’s 1988-2008 housing stock. We install insulated 316Ti stainless liners, rated for continuous high-temperature duty, through existing metal chases without opening walls. A typical stainless liner replacement in Upper Nazareth runs $2,200-$3,800, including removal of the damaged original and full camera verification of the new installation. These liners handle Northampton County’s five-month burning season without the degradation that destroys lesser materials.

Flexible Liner for Offset Flues
Some Upper Nazareth prefab chases have offsets or tight bends that rigid pipe cannot navigate. Our flexible liner installations, using DuraFlex and Olympia Chimney products, thread through these constrained spaces while maintaining full insulation and structural integrity. Flexible liner jobs in Upper Nazareth typically cost $2,600-$4,200, depending on chase height and offset complexity. We size every installation to the appliance’s BTU rating, not guesswork.

Liner Replacement for Factory-Built Fireplaces
This is the core of our Upper Nazareth work. Factory-built fireplaces from Heatilator and similar manufacturers were installed by the thousands in this township, and their original aluminum or light-gauge venting was never meant to last thirty years. We pull the old liner, inspect the chase interior for water damage or corrosion, and install a replacement matched to the unit’s specifications. Liner replacement in Upper Nazareth generally falls between $1,800-$3,200. We stock the brand-specific parts to complete most of these in one day.

Partial Rebuild of Prefab Firebox and Chase
When the firebox itself has failed, refractory panels, throat dampers, and chase covers need coordinated replacement. Our Chimney Liner & Rebuild team handles partial rebuilds that restore factory-built units to safe, code-compliant operation without the cost of full masonry reconstruction. Partial rebuilds in Upper Nazareth range from $2,800-$4,500. On a block off Georgetown Road, our tech opened three colonials built within two years of each other and found the same seized throat damper and fractured rear firebox panel in all three - the telltale signature of one builder’s single prefab model run. We swapped in new refractory panels, freed and reseated the dampers, and dropped an insulated stainless liner through the chase on the worst one where the original venting had corroded. Because we had Heatilator parts on the truck, all three were back to safe burning before the first cold snap.

Trusted Brands We Service in Upper Nazareth
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - no builder-grade substitutes that fail in Northampton County’s freeze-thaw cycles. For Upper Nazareth’s prefab-concentrated housing stock, this means stocking Heatilator-compatible refractory panels, chase covers sized to common local chase dimensions, and insulated liners rated for the continuous use these homeowners actually demand. Parts sit on our trucks, not in a warehouse three states away. That stockpile is what lets us complete most Upper Nazareth liner and rebuild jobs in a single visit, with the number on the estimate matching the number on the invoice.
Common Chimney Liner & Rebuild Problems We See in Upper Nazareth Homes
- Cracked refractory firebox panels in 20-to-30-year-old factory-built units. The dominant failure across Upper Nazareth’s 1988-2008 subdivisions. These panels shield surrounding combustibles from direct flame, and when they fracture, the fireplace is unsafe to operate. This is not masonry spalling. It’s a prefab-specific failure pattern we see repeated street by street.
- Rusted-through galvanized chase covers and warped shallow-pitch caps. Annual snow and ice loading from Northampton County nor’easters cracks and warps these covers, letting meltwater run down the chase. By the time a homeowner notices water stains inside, the liner and firebox behind the wall have already corroded. We replace with Gelco and Copperfield stainless covers rated for the load.
- Second- and third-degree glazed creosote. Upper Nazareth’s five-month burning season, November through March, produces heavy accumulation in flue liners never rated for continuous use. Glazed creosote cannot be brushed out. It requires chemical treatment or liner replacement, and it is a legitimate chimney fire hazard.
- Seized or misaligned throat dampers. Common in the mid-tier prefab models installed across Upper Nazareth’s planned subdivisions. A damper that won’t open or close completely wastes heat, invites downdrafts, and in some cases prevents safe ignition. We free, reseat, or replace with factory-matched components.

FAQs - Chimney Liner & Rebuild in Upper Nazareth
It likely needs liner replacement if the original venting is corroded or glazed, and possibly partial rebuild if refractory panels or the damper have failed. Homes from the mid-1990s are now hitting the 25-30 year mark where factory-built components reach end of rated life. We inspect with a camera, show you the photos, and tell you straight whether a liner swap, panel replacement, or more extensive rebuild is warranted. Call (610) 595-5754 to schedule - estimates are free.
Because entire Upper Nazareth subdivisions were built with the same Heatilator or similar prefab models in the same two- or three-year window, we see identical failures repeated house after house. Stocking those parts lets us fix your fireplace today, not in two weeks after a parts order arrives. Other sweeps treat every call as a one-off. We know these streets.
Yes. In Upper Nazareth, even occasional use lets moisture infiltrate through rusted chase covers, and freeze-thaw cycles damage refractory panels whether the fireplace runs daily or twice a winter. An annual Level-2 inspection catches chase cover failure and liner corrosion before they become rebuilds. The $89 Seasonal Tune-Up is cheaper than deferred maintenance.
Unlike neighboring Nazareth Borough, where older masonry chimneys need clay-flue and crown work, Upper Nazareth’s 1988-2008 prefab stock requires brand-specific replacement parts and chase-specific protocols. A “rebuild” here usually means firebox panels, dampers, liners, and chase covers - not brick and mortar. Using masonry methods on a prefab chase damages the unit and voids any remaining warranty.
We install DuraFlex and Olympia Chimney flexible liners, and rigid 316Ti stainless systems from Copperfield and Gelco, all sized and insulated to the appliance’s specifications. No generic substitutes. Every liner carries a manufacturer warranty plus our 90-Day Done Right Promise in writing. Call (610) 595-5754 to confirm fit for your specific factory-built unit.
If your Upper Nazareth fireplace is showing its age, don’t guess at what’s wrong. We’ll camera-inspect it, show you exactly what we find, and give you a plain-English verdict with a price that won’t change. Our 90-Day Done Right Promise means if it’s not right, we come back. No paperwork. No arguing. Done right, and we stand behind it. Call (610) 595-5754 today - a live person answers, 24 hours a day, 7 days a week.
