Why Hearthstone Chimney Co. of New York City Is Clark’s Preferred Chimney Repair Company

We’ve been serving Union County homeowners for over 42 years, and Clark’s mid-century housing stock is some of the most familiar territory our technicians cover. The township’s dense grid of post-WWII ranches, capes, and split-levels - nearly all built between 1948 and 1972 - presents chimney problems we see nowhere else in quite the same concentration. That familiarity matters. When our truck pulls up to a home off Westfield Avenue or along the residential streets near the Garden State Parkway, our technician already knows the likely flue configuration, the probable mortar condition, and whether the chimney height meets modern code.

Our reputation in Clark is built on documentation, not promises. Every Level-2 camera inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. The 90-Day Done Right Promise governs every job - Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we come back. In writing, no arguing.

Calls are answered by a live person, 24/7. Not a voicemail, not a callback queue. Background-checked, uniformed technicians. Most jobs completed in a single visit. No-hassle upfront pricing - the number on the estimate is the number on the invoice.

Our Chimney Repair Services in Clark

Chimney Rebuilding

Some Clark chimneys have simply reached the end of their service life. The freeze-thaw cycling in Union County - roughly 28 inches of snow annually, with genuine temperature swings that push water deep into brick pores - destroys 60-70-year-old masonry from the inside out. When spalling has compromised multiple courses, when the crown has disintegrated entirely, or when the chimney has begun to lean, spot repairs won’t hold. We rebuild using new brick matched for color and texture, with professional-grade materials from Olympia Chimney and Copperfield. On a 1956 bi-level on Old Raritan Road, we found the shared flue for a gas furnace and wood fireplace had a collapsed terra-cotta liner. We installed a DuraFlex stainless steel liner sized for the gas insert, then extended the chimney 18 inches above the ridge to fix a year-long downdraft issue the homeowner had blamed on the damper. Full rebuilds in Clark typically range $3,200-$6,500.

Mortar Repointing

The mortar joints on Clark’s original chimneys are now 60-70 years old and actively failing. Union County’s freeze-thaw cycle accelerates the damage - water enters hairline cracks in fall, expands through January and February, and opens gaps that let more water in come spring. Repointing removes deteriorated mortar to proper depth and replaces it with a matching mix, color-blended to the original. We complete most repointing jobs in Clark in one day. Typical range: $1,200-$2,800.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - is the signature damage we find on Clark chimneys every spring. The brick was never designed to absorb the thermal stress of decades of freeze-thaw. We replace spalled bricks with matching units and address the underlying moisture intrusion, usually failed crown or flashing. Individual brick replacement runs $180-$340; section rebuilds where spalling is widespread range $800-$1,600.

Flashing Repair

The step flashing and counterflashing on Clark’s 1950s-1960s ranches was often installed as a single piece of galvanized steel, now rusted through or separated from the brick by decades of thermal movement. Water enters at the roofline and runs down the framing, showing up as ceiling stains or attic moisture. We fabricate custom flashing from professional-grade materials and integrate it properly with the roofing system. Flashing repair in Clark: $450-$950; full replacement where the chimney passes through a complex roof plane runs $1,100-$1,800.

Chimney Waterproofing

After any masonry repair, waterproofing with a vapor-permeable sealant extends the life of the work by preventing water absorption while allowing the brick to breathe. We use professional-grade formulations from HeatShield. Application on a typical Clark ranch chimney: $380-$650.

Trusted Brands We Service in Clark

We stock parts and materials from Gelco, Olympia Chimney, and Famco - brands that meet our standard for professional-grade performance, not builder-grade substitutes that fail in five years. For Clark homeowners, this means faster turnaround. When we diagnose a problem during your Level-2 inspection, we rarely need to order parts and return. The liner, the crown, the cap, the flashing - most of it travels in our truck. Done right, and we stand behind it.

Common Chimney Repair Problems We See in Clark Homes

• Shared flues violating modern clearance codes. Clark’s original chimneys were sized for coal or oil furnaces, then informally retrofitted for wood-burning fireplaces or gas inserts. The dual-use design that serves both furnace and living-room fireplace now violates code once any appliance is upgraded. We find this on nearly every inspection of unmodified 1950s-1960s homes.
• Low chimney height causing chronic downdraft. Many Clark ranches have chimneys that exit the roofline at just 2-3 feet above the ridge, a 1950s builder shortcut that violates the 2-foot-above-10-foot rule. Homeowners blame the damper. The real fix is a liner extension and proper termination height.
• Freeze-thaw mortar failure. Union County’s winter cycling destroys 60-70-year-old mortar joints from within. Spring inspections after January-February cold snaps consistently reveal damage that accumulated unseen during the heating season.
• Original flashing rusted and separated. Single-piece galvanized step flashing from the original construction has outlived its design life. Water intrusion at the roofline is often the first symptom homeowners notice.
