Call (610) 609-7634

Nazareth isn’t like the surrounding townships. The Moravian-era stone and brick homes at the borough’s core, many dating to the 1740s-1890s, were built with unlined rubble-and-mortar chimneys designed for wood and coal combustion. When we get a call from a homeowner near Center Square or along South Main Street, we know there’s a good chance we’re walking into a liner assessment, not just a routine sweep. The freeze-thaw cycling through Northampton County pounds the aged lime mortar in these flues, and the heavy wood-stove use that gets families through Nazareth’s sustained below-freezing winters from December through February loads creosote at rates that surprise newer residents. We’ve learned to bring the camera, the liner inventory, and the patience these chimneys demand.

Why Hearthstone Chimney Co. Is Nazareth’s Preferred Chimney Repair Company

We’ve been answering calls with a live person, 24 hours a day, 7 days a week, for over 42 years. That matters in Nazareth, where a chimney problem in January doesn’t wait for business hours. When you call (610) 609-7634, you reach a person who can schedule a technician, not a callback queue.

Our technicians are background-checked, uniformed, and trained to handle what Nazareth’s housing stock throws at them. They know the difference between a 1980s ranch on the outskirts and an 1800s Federal brick row home near the historic district. They know the slate roofs on those older homes crack under standard ladder placement, and they know how to work around them.

Every inspection ends with photos you can see and a plain-English verdict. If we find joint deterioration in an unlined rubble flue, we show you. If the mortar needs repointing before next burning season, we explain why. Nothing is recommended without evidence you can verify yourself.

Our Chimney Repair Services in Nazareth

Mortar Repointing

The lime mortar in Nazareth’s pre-1900 chimneys wasn’t formulated for modern Portland cement standards, and the freeze-thaw cycles here exploit that weakness aggressively. We grind out deteriorated joints to proper depth and repoint with mortar matched to the original composition and compressive strength, preserving the chimney’s breathability while restoring structural integrity. In the historic district near the Moravian buildings, this is often the difference between a chimney that lasts another century and one that fails joint-by-joint within a decade.

Spalling Brick Repair

Spalling, the flaking and crumbling of brick faces, is epidemic on Nazareth’s older chimneys where moisture has penetrated and frozen repeatedly. We remove damaged brick, assess the underlying structure, and install replacements matched for color and absorption rate so the repair doesn’t announce itself from the street. On a recent call near New Street, we found spalling so advanced that the freeze-thaw damage had reached the wythes; the homeowner had assumed it was cosmetic until our camera inspection showed the draft path compromised.

Chimney Rebuilding

When deterioration exceeds what repointing or selective brick replacement can address, we rebuild. This is more common in Nazareth than in newer Lehigh Valley townships because the unlined rubble-and-mortar construction of the borough’s oldest chimneys allows hidden decay to progress further before symptoms appear. We rebuild with proper flue liners installed, using professional-grade materials from Olympia Chimney and Famco, and we document every stage with photos for the homeowner’s records.

Chimney Waterproofing

Nazareth’s 30 inches of annual snowfall and sustained winter cold create ideal conditions for moisture intrusion through porous brick and failed crown seals. We apply vapor-permeable waterproofing agents that allow the chimney to breathe while repelling liquid water, critical for historic masonry that was never intended to be sealed with modern film-forming coatings. This is especially important for homes near the Bushkill Creek drainage, where humidity and groundwater pressure compound the weather exposure.

Flashing Repair

Step flashing and counterflashing failures around chimney penetrations are a leading source of the “mystery leaks” Nazareth homeowners call us about after heavy snowmelt. We fabricate and install custom flashing with proper overlap and sealant integration, and on slate-roofed homes, we take extra care with anchor points to avoid the cracking that standard practices cause. A proper flashing repair on an 1800s slate roof requires a different approach than the same job on asphalt shingles, and our technicians know which they’re walking into before they set the ladder.

Trusted Brands We Service in Nazareth

We stock professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco, brands we’ve specified for decades because they hold up in Nazareth’s conditions. HeatShield’s cerfractory flue liner resurfacing system, for instance, is often the right solution for an unlined Moravian-era chimney that needs structural restoration without the disruption of a full stainless liner installation. We keep common sizes and configurations in inventory so Nazareth customers aren’t waiting weeks for parts while their chimney sits unusable through another cold snap. When we specify a brand, it’s because we’ve installed it, watched it age, and know it performs. No builder-grade substitutes pass through our shop.

Common Chimney Repair Problems We See in Nazareth Homes

• Unlined rubble-and-mortar flues failing from freeze-thaw cycling. The oldest chimneys in Nazareth’s historic district were built without terra cotta flue liners, and the lime mortar joints between stones deteriorate progressively as moisture penetrates and freezes. By the time a homeowner notices drafting problems or a smoky fireplace, the damage is often extensive enough to require liner retrofit or rebuild.
• Third-degree creosote glazing from heavy wood-stove use. Nazareth’s sustained below-freezing winters drive intensive burning, and first-degree fluffy creosote degrades into third-degree tar glaze that standard brushes cannot remove. This requires chemical treatment or rotary removal, and it’s a fire hazard that develops faster than most owners expect.
• Spalling brick and deteriorated mortar from decades of weather exposure. The borough’s 18th- and 19th-century brick chimneys have endured nearly two centuries of Northampton County freeze-thaw cycling, and the surface damage is often worse than it appears from the ground. Our camera inspections regularly reveal internal spalling that hasn’t yet broken through the outer wythe.
• Fragile slate roofs cracked by improper ladder placement during repairs. The original slate on 1800s-era Nazareth homes is brittle and unforgiving; a standard ladder shoe or careless foot placement cracks slates that haven’t been manufactured for a century. This creates hidden leaks into attic framing that may not show interior damage for months.
