We’ve been driving to Mount Lebanon since 1984. We know the brick Tudors along Washington Road, the steep-pitched Colonials near Mount Lebanon Park, and the tight lots in Virginia Manor where scaffolding space is measured in inches, not feet. The chimneys here are old, proud, and often hiding problems that started decades before the current owner moved in. That’s not a scare tactic. It’s what we find on inspection after inspection.

Why Hearthstone Chimney Co. Is Mount Lebanon’s Preferred Chimney Repair Company

Mount Lebanon developed primarily between the 1920s and 1950s as a streetcar suburb of Pittsburgh - when the region still ran on coal. Nearly every masonry chimney in the borough was originally engineered for coal combustion, then quietly converted to gas or oil heat mid-century, leaving flues that are oversized, often unlined or cracked, and prone to backdrafting with modern appliances. This coal-to-gas conversion legacy makes chimney relining and camera inspection a far more urgent service here than simple creosote sweeping. Our Chimney Repair team carries this history into every job.

After 42 years in the South Hills, we’ve worked on chimneys you can see from Bower Hill Road and others tucked behind garages on Beverly Road where the access is so tight we had to build custom scaffolding. Homeowners here remember contractors who never called back. We answer the phone with a live person, 24 hours a day, 7 days a week. No voicemail. No callback queue.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. When Russell Haines started this company in 1984, he believed a homeowner should understand exactly what’s wrong before spending a dollar. That hasn’t changed. Every technician is background-checked and uniformed. Most jobs finish in one visit. The price we quote is the price on the invoice - a square deal, no surprises on the bill.

We’re not a price-cutting chain, and we’re not a one-truck operator who might answer the phone next year. We plan to be repairing chimneys in Mount Lebanon thirty years from now. That changes how we treat every job.

Our Chimney Repair Services in Mount Lebanon

Mortar Repointing

The freeze-thaw cycle in Mount Lebanon’s South Hills location chews through mortar joints faster than in milder climates. Temperatures oscillate around freezing all winter, water seeps into hairline cracks, expands, and opens gaps wide enough to slide a putty knife through. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade mortar formulated for Pittsburgh’s climate. On a typical Mount Lebanon Tudor near Cedar Boulevard, expect repointing to run $1,200-$2,800 for the upper stack, depending on accessibility and how many courses need attention.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - is epidemic on Mount Lebanon chimneys where original coal-era construction meets decades of moisture intrusion. The borough’s mature oak and maple canopy is beautiful, but those leaves clog gutters and crown washes, directing water straight into brickwork. We remove spalled bricks, source matching replacements when possible, and rebuild with proper bonding patterns. In the Virginia Manor neighborhood, where many homes date to the late 1920s, we’ve replaced entire chimney faces where the brick had deteriorated to sand. Spalling repair in Mount Lebanon typically costs $800-$2,400.

Chimney Waterproofing

Water is the enemy of every masonry chimney, and Mount Lebanon’s combination of aging brick, dense tree cover, and freeze-thaw cycling makes waterproofing a smart preventive investment. We apply vapor-permeable sealers from professional-grade lines like Copperfield and Famco - never the hardware-store coatings that trap moisture inside and accelerate damage. A proper waterproofing treatment on a standard Mount Lebanon chimney runs $450-$950 and carries our 90-Day Done Right Promise: if water penetrates where we treated, we come back, in writing, no arguing.

Flashing Repair

Step flashing and counterflashing around chimney penetrations fail predictably on Mount Lebanon’s older homes, where original galvanized steel has rusted through or where previous roofers caulked over problems instead of rebuilding. We fabricate custom flashing from long-wearing materials and integrate it properly with your roofing system. On the steep pitches common along Cochran Road and throughout the Sunset Hills area, this requires experience with angled work and proper ice-and-water shield integration. Flashing repair in Mount Lebanon generally runs $650-$1,800.

We also handle Chimney Cap & Crown in Mount Lebanon when the damage extends beyond flashing, and our Fireplace Services in Mount Lebanon cover the interior systems connected to these chimneys.

Trusted Brands We Service in Mount Lebanon

We stock professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - the brands that other contractors in the South Hills often have to special-order. For a Mount Lebanon homeowner, that means faster turnaround and no compromises on quality. When we recommend a Chimney Liner & Rebuild - Mount Lebanon solution using DuraFlex stainless steel or a crown rebuild with HeatShield’s engineered refractory, it’s because we’ve installed thousands and we know how they perform in Pittsburgh’s freeze-thaw environment. We don’t use builder-grade substitutes, and we don’t mark up parts you could buy yourself for less. Our pricing is straightforward: the materials cost what they cost, the labor is quoted upfront, and the total is the total.

Common Chimney Repair Problems We See in Mount Lebanon Homes

• Original coal-era flues venting modern gas appliances. Technicians working Mount Lebanon regularly find original coal-era ash pit doors still intact in basements - a tell-tale sign the flue diameter was never reduced or relined when the home switched to gas, meaning the homeowner has likely been running an appliance vented into a dangerously oversized, unlined flue without knowing it. This is a genuine safety hazard that requires immediate Level-2 inspection.
• Cracked clay tile liners from thermal cycling. Mount Lebanon’s housing stock includes clay tile flue liners from the 1920s through 1950s that are commonly cracked or offset from decades of expansion and contraction. These liners were never designed for the rapid temperature swings of modern heating cycles, and the damage is often invisible from the outside until a camera inspection reveals it.
• Crown deterioration from freeze-thaw and debris accumulation. The borough’s dense tree canopy deposits significant leaf and debris accumulation each fall, trapping moisture against chimney crowns. Combined with Pittsburgh’s pronounced freeze-thaw cycle, this accelerates concrete spalling and opens pathways for water into the chimney structure.
• Mortar erosion on exposed upper stacks. Chimneys rising above the roofline on Mount Lebanon’s steep-pitched homes take the full force of wind-driven rain and temperature swings. Mortar joints on the weather side often erode to powder while the leeward side looks fine - a pattern we check for on every inspection.
