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.

Bath sits at the base of Blue Mountain, and that position matters more than most homeowners realize. Cold air drains off the ridge straight into the borough, hammering 150-year-old brick chimneys with freeze-thaw cycles that crack crowns and spall mortar years earlier than the same-age masonry down in the flatter southern Lehigh Valley. We’ve spent over 42 years repairing chimneys in Pennsylvania German towns exactly like this one. We know what fails here, and we know why.
Why Hearthstone Chimney Co. Is Bath’s Preferred Chimney Repair Company

Our 90-Day Done Right Promise is backed in writing with no arguing. If it’s not right, we make it right.

Our Chimney Repair Services in Bath
Mortar Repointing
The freeze-thaw cycling in Bath opens mortar joints faster than homeowners expect. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade mortar formulated for Pennsylvania’s winter extremes. In the historic borough center, we match the original lime-based mortars where appropriate, preserving both structure and appearance.
Spalling Brick Repair
Spalled brick is everywhere in Bath’s older housing stock. Water enters through cracked crowns or open joints, freezes, and pops the brick face. We remove damaged brick, rebuild with matching units, and address the water source so it doesn’t happen again. Our techs carry common Pennsylvania German brick profiles to maintain the original character of your chimney.
Chimney Waterproofing
This is critical in Bath. Wind-driven rain off Blue Mountain saturates masonry that already faces aggressive freeze-thaw. We apply vapor-permeable waterproofing agents that let the chimney breathe while blocking water entry. Unlike cheap sealers that trap moisture and accelerate damage, our treatments work with the masonry, not against it. For chimneys in the historic core that have never been treated, waterproofing often adds a decade of service life.
Flashing Repair
Flashing failure is one of the most misdiagnosed problems we see in Bath. Wind-driven storms lift the uphill-side flashing, water tracks down the chimney chase, and months later a rust-brown stain appears on the ceiling. Homeowners call roofers; roofers patch shingles; the stain returns. We inspect the chimney-to-roof interface with our Level-2 camera, reset or replace flashing with proper step and counterflashing techniques, and verify the seal. Done right, and we stand behind it.
Chimney Rebuilding
Some Bath chimneys have simply exceeded their service life. When mortar loss exceeds 30 percent, when the smoke chamber is eroded, or when structural integrity is compromised, partial or full rebuilding becomes the honest recommendation. We rebuild with matching brick, proper flue sizing, and modern liners where needed. Every rebuild includes a written 90-Day Done Right Promise.
Tuckpointing
For Bath’s historic properties where aesthetic preservation matters, tuckpointing restores the fine-line mortar appearance of original Pennsylvania German brickwork. This is specialized craft work, and our technicians are trained in the technique.

Trusted Brands We Service in Bath
We stock professional-grade materials from HeatShield, DuraFlex, and Olympia Chimney so Bath repairs don’t wait on parts orders. HeatShield’s cerfractory sealant handles smoke chamber parging and flue resurfacing in the older chimneys we see throughout the borough. DuraFlex liners solve the unlined flue problems left by mid-century conversions. Olympia Chimney caps and components stand up to the wind exposure at the base of Blue Mountain. No builder-grade substitutes. The right material for the actual problem.
Common Chimney Repair Problems We See in Bath Homes
- Wind-driven flashing failure. Storms rolling off Blue Mountain lift chimney flashing on the uphill side. Water enters the chase, travels down unlined flues, and appears as ceiling stains that get blamed on the roof. We find the actual source with camera inspection.
- Crown cracking from freeze-thaw. Bath’s cold-air drainage exposes chimney crowns to more extreme temperature swings than sheltered Lehigh Valley locations. Cracked crowns let water into the masonry core, where freeze-thaw spalls brick and erodes the smoke chamber.
- Mid-century coal-to-gas conversion damage. Oversized, unlined clay-tile flues condensate heavily during heating season. Tile joints weep dark staining down interior walls. Homeowners request chimney cleaning, but the root issue is a flue never properly sized or lined for gas. This is a code deficiency grandfathered in on properties untouched for 50 years.
- Shared flue hazards. Many Bath rowhouses route both fireplace and heating appliance through a single flue, sometimes with no liner at all. Carbon monoxide risk is real and unambiguous. Our Level-2 inspection documents the configuration and gives you a plain-English verdict on what must be addressed.

FAQs - Chimney Repair in Bath
Wind-driven rain off Blue Mountain hits the uphill side of your chimney with force that ordinary rainfall doesn’t generate. That pressure lifts flashing edges, drives water through cracked crowns, and exploits any open mortar joint. The leak often appears inside days or weeks later, after water has tracked down the flue or chase. We inspect with a Level-2 camera to find the entry point, document it with photos, and repair the actual source. Call (610) 609-7634 for a free inspection.
Almost certainly yes, and this is one of the most common serious issues we find in Bath’s historic core. Mid-century conversions typically left oversized, unlined clay flues that were never properly sized for gas appliance temperatures and draft characteristics. The flue condensates, draft is poor, and carbon monoxide risk is elevated. Our camera inspection shows you the flue condition directly. If relining is needed, we size a DuraFlex or HeatShield system to your specific appliance and provide a written compliance assessment. Estimates are free.
Annually, without exception. Bath’s position at the base of Blue Mountain subjects chimneys to more aggressive freeze-thaw cycling than flatter Lehigh Valley locations. A crown that was sound last October can be cracked by April. The National Fire Protection Association recommends annual Level-2 inspection for all solid-fuel systems and any chimney that has experienced damage or weather events. Given Bath’s exposure, we believe that standard should be treated as a minimum. Call (610) 609-7634 to schedule.
Look for three things you can see from the ground: new gaps or cracks in the chimney crown, missing or shifted chimney cap, and any new staining on interior walls or ceilings near the chimney. Then look up the flue with a flashlight for visible obstructions or heavy soot buildup. Do not climb the roof. The critical checks, flue condition and structural integrity, require a Level-2 camera inspection that we perform from inside and on the roof. Schedule your inspection before you light the first fire. Call (610) 609-7634.
No. Dark staining from a weeping flue is caused by condensate and combustion byproducts migrating through deteriorated tile joints in an unlined or improperly lined flue. Brushing removes soot from the flue surface but does not seal the joints or correct the underlying draft and condensation problem. The stain will return, and the carbon monoxide risk remains. We camera-inspect to confirm the source, then recommend proper relining with a system sized to your appliance. Call (610) 609-7634 for a free second opinion if you’ve been told otherwise.
