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.

Why Hearthstone Chimney Co. Is Upper Nazareth’s Preferred Fireplace Services Company
Upper Nazareth homeowners know the difference between a contractor who shows up and one who disappears. We’ve built our reputation on being the former. Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics, just the facts about what’s happening inside your chimney.
We understand Upper Nazareth’s housing stock because we’ve worked it for decades. The township’s rapid growth from the 1990s through the 2010s means most homes here have factory-built zero-clearance prefabricated fireplaces, not the masonry chimneys you’ll find in neighboring Nazareth Borough. That matters. A prefab unit at 25 years old is nearing the end of its UL-listed service life, and the problems we find are different: cracked refractory panels, rusted chase covers, failed firestop spacers. You need a crew that knows what to look for.
Our 90-Day Done Right Promise governs every job. If it’s not right, we make it right. In writing, no arguing. That’s the Keystone Standard, and it’s how we’ve operated since 1984.
Calls are answered by a live person 24 hours a day, 7 days a week. Not voicemail. Not a callback queue. A real person.
Our Fireplace Services in Upper Nazareth
Wood Burning Fireplace Service
Wood burning fireplaces in Upper Nazareth work harder than most. The Lehigh Valley’s sustained below-freezing temperatures from December through February push residents to burn heavily, and prefab units with their narrower flue diameters accumulate creosote faster than masonry chimneys. Low-burn shoulder-season operation makes it worse, glazing the flue with Stage 2-3 creosote that a standard brush pass won’t touch. We were called to a colonial on the rural edge of Upper Nazareth where the homeowners burn a wood stove insert as their primary heat from November through March, and our tech found third-degree creosote glazing the narrow prefab flue - the kind of tar glaze a brush cannot remove - plus a cracked refractory panel and a rusted-through chase cover from two decades of Lehigh Valley freeze-thaw cycling. We swept what could be swept, HeatShield-coated the firebox cracks, replaced the chase cover, and set the household on a shorter annual service interval with a draft-check each fall. Done right, and we stand behind it.

Fireplace Insert Installation & Service
Inserts are popular in Upper Nazareth’s 1990s-2010s tract homes because they retrofit into existing prefab fireboxes for better efficiency. But an insert installed without proper liner connection is a carbon monoxide risk. We inspect the full system: the insert, the liner, the connection point, the termination cap. If you’re burning an insert as primary heat, you need a shorter service interval than the standard annual recommendation. We’ll tell you exactly what we find and what it costs to fix. No surprises on the bill.

Firebox Repair
Cracked refractory panels are the most common firebox problem we see in Upper Nazareth. Homeowners assume their “newer” prefab fireplace is low-maintenance, so they skip inspections until the cracks are visible from across the room. We can often repair minor cracking with HeatShield cerfractory coating, a professional-grade product that restores the panel’s insulating properties. For panels cracked through or heat-damaged beyond repair, we source replacements from Olympia Chimney and Copperfield to match your unit’s specifications. We never recommend replacement without showing you the damage on camera.

Gas Fireplace Service
Gas fireplaces in Upper Nazareth’s subdivision homes need annual inspection too. Burner ports clog with dust, thermocouples weaken, and venting systems can develop leaks. We test gas pressure, inspect the burner assembly, check the pilot and safety shutoffs, and verify venting integrity. Most gas service calls in Upper Nazareth are completed in a single visit with parts from our stocked inventory.

Damper Repair
A stuck or rusted damper wastes heat and can prevent proper draft. In Upper Nazareth’s prefab units, we often find dampers corroded from condensation in the chase, especially on north-facing walls where freeze-thaw cycling is most aggressive. We repair or replace with components from Famco, matched to your unit’s make and model.

Trusted Brands We Service in Upper Nazareth
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from Gelco, Olympia Chimney, Famco, and Copperfield, the brands that factory engineers specify. For Upper Nazareth homeowners, that means faster turnaround. We don’t order parts and make you wait two weeks. We diagnose, show you the photo, pull the right component from stock, and complete most jobs in a single visit. That’s how we’ve worked for over 42 years.
Common Fireplace Services Problems We See in Upper Nazareth Homes
- Refractory panels cracked through from thermal shock. In Upper Nazareth’s subdivision neighborhoods, technicians regularly find homeowners who have never scheduled a chimney cleaning because they assume a “newer” prefab fireplace is low-maintenance - only to discover the refractory firebox panels are cracked through and the chase cover is rusted out after two decades of Lehigh Valley freeze-thaw cycling. These panels insulate the metal firebox from extreme heat. Once cracked, they must be repaired or replaced.
- Glazed Stage 2-3 creosote in narrow prefab flues. Low-burn shoulder-season operation in prefab units with narrow flue diameters drives glazed creosote that a standard sweeping pass will not remove. We use rotary cleaning systems and chemical treatments when necessary.
- Failed firestop spacers and corroded triple-wall flue sections. These hidden components behind the chase trim panels go unnoticed during basic surface cleaning. We pull the panels and inspect the full system, not just what’s visible.
- Rusted chase covers and deteriorated chase flashing. Upper Nazareth’s freeze-thaw cycles - especially on homes along rural roads with more wind exposure - accelerate rust on galvanized chase covers. A rusted-through cover lets water into the chase, damaging the flue and surrounding structure.

FAQs - Fireplace Services in Upper Nazareth
Yes. A 2000s-era prefab fireplace in Upper Nazareth is now 20-25 years old, squarely in the window where UL-listed service life expires. We regularly find cracked refractory panels, rusted chase covers, and failed firestop spacers in “newer” homes where owners assumed low maintenance meant no maintenance. Call (610) 756-1504 for a free evaluation - estimates are free.

Twice per burning season if you’re running daily from November through March, with a draft-check each fall before first fire. Heavy use in a prefab insert loads creosote faster than occasional ambiance burning, and Upper Nazareth’s cold winters mean sustained operation that narrows flues quickly. We set rural Upper Nazareth wood-burning households on this shorter interval after their first heavy-creosote discovery. Call (610) 756-1504 to schedule - estimates are free.

Your prefab unit is a metal box with refractory panels and a triple-wall flue, built to UL standards with a finite service life of roughly 20-30 years. Your parents’ masonry chimney in Nazareth Borough was brick and mortar, rebuildable indefinitely. The problems, repair methods, and end-of-life decisions are completely different. We evaluate prefab units against manufacturer specifications, not masonry standards. Call (610) 756-1504 if you’re unsure what you have - estimates are free.

Minor to moderate cracking can often be repaired with HeatShield cerfractory coating, restoring the panel’s insulating properties. Panels cracked through, heat-damaged, or delaminated require replacement. We never recommend replacement without camera evidence you can see yourself, and we’ll tell you plainly when a repair can safely wait versus when it cannot. Call (610) 756-1504 for an exact assessment - estimates are free.

Burn seasoned hardwood (20% moisture or less) at active flame temperatures, not smoldering low burns. In Upper Nazareth’s narrow prefab flues, low-temperature shoulder-season operation is the primary driver of glazed creosote. Use smaller, hotter fires rather than loading the box and choking air. Let the flue reach operating temperature before reducing draft. We’ll demonstrate proper technique during your service call. Call (610) 756-1504 to schedule - estimates are free.
