Call (844) 660-6590

We’re based in Yonkers and regularly work the village streets of Harrison, from the 1920s colonials near Harrison Avenue to the cape cods off Halstead Avenue and the two-family homes around Westchester Avenue. Our Chimney Repair team knows these chimneys: oversized terra cotta flues originally built for coal, later converted to oil, now running too cool and too wet. Gary Murphy, our owner and lead technician, personally handles the inspection and repair work on Harrison jobs—no subcontracted crews, no handoffs.

In Harrison specifically, we’ve built a reputation for diagnosing problems that other sweeps miss—particularly the low-draft, high-condensation issues in pre-1955 masonry chimneys.

Our response time to Harrison is typically same-day or next-day for urgent calls, especially during the post-winter inspection rush when freeze-thaw damage reveals itself. We carry HeatShield and DuraFlex liner materials on our truck, which means most Harrison repairs don’t wait on parts.

Here’s what separates our work: Gary leads every job himself. When you call (844) 660-6590, you speak to the person who will be on your roof. That matters in a trade where the difference between a proper liner sizing and a guess can mean another winter of soot glaze and petroleum odors creeping into your second floor.

Our Chimney Repair Services in Harrison

Chimney Rebuilding

Some Harrison chimneys—particularly the single-stack masonry structures serving both fireplace and heating appliance on 1930s colonials—have simply reached the end of their service life. Decades of coal, oil, and gas combustion have degraded the interior, while Westchester’s 30–40 annual freeze-thaw cycles have eroded the exterior. We rebuild from the crown down or the roofline up, matching original brick and fieldstone where possible. On a recent job near Purdy Street, we rebuilt a chimney that had lost its crown and three courses of brick to ice damage—work that required temporary heat containment so the homeowner’s boiler could stay online through the repair.

Mortar Repointing

The mortar joints on Harrison’s 1920s–1950s chimneys weren’t formulated for modern freeze-thaw stress. Original lime-based mortar is softer and more porous than today’s Portland mixes, which means it absorbs more water and deteriorates faster when temperatures swing. We remove failed joints to proper depth—typically ¾ to 1 inch—and repoint with mortar matched to the original composition and color. On fieldstone chimneys common near the Harrison train station area, this is especially critical: irregular stone edges require hand-packed joints, not troweled-on slurry, or the repair fails in two winters.

Chimney Waterproofing

Harrison’s mature tree canopy and northern exposures keep masonry damp longer than sun-baked new construction. We apply vapor-permeable sealants—never film-forming coatings that trap moisture—specifically formulated for freeze-thaw climates. The goal is to let the chimney breathe while shedding bulk water. This is preventive work that pays off most on chimneys with sound mortar but aging crowns, buying time before repointing or rebuilding becomes necessary.

Flashing Repair

Step flashing and counterflashing on Harrison’s older homes often date to the last roof replacement—or the one before that. Galvanized steel rusts at the mortar joint; aluminum separates from brick movement. We fabricate custom flashing on-site to match your roof-to-chimney intersection, using copper or lead-coated copper where longevity matters. On low-slope sections common on Harrison’s cape cods with shed dormers, we pay particular attention to headwall flashing integration—an area where water finds its way in slowly, then rots the rafter tail before anyone notices.

Trusted Brands We Service in Harrison

We install and work with professional-grade materials because Harrison’s chimneys punish inferior products. For liner installations and restorations, we use HeatShield cerfractory systems and DuraFlex stainless steel liners—materials rated for the acidic condensate produced by modern, efficient appliances connected to old, oversized flues. For caps, dampers, and repair components, we source Gelco and Olympia Chimney products, both of which hold up to Westchester’s freeze-thaw cycling better than big-box alternatives. We keep common sizes in stock, so most Harrison repairs don’t get delayed waiting on a warehouse shipment.

Common Chimney Repair Problems We See in Harrison Homes

• Petroleum odors on the second floor. We hear this constantly from Harrison homeowners: “My boiler smells.” It’s usually not the boiler. An oversized terra cotta flue—originally built for coal, now serving an oil burner—runs too cool. Exhaust condenses on the liner, mixes with soot, and produces a sticky, oily glaze. That smell migrates through wall cavities into upstairs rooms. The fix is a properly sized stainless steel liner, not a service call to your HVAC company.
• Spalling brick and deteriorated crowns after winter. Harrison’s 30–40 annual freeze-thaw events force water trapped in masonry to expand and contract. Crowns crack first; then water gets behind the brick face, which pops off in sheets by March. Annual inspection in April catches this before it reaches the flue.
• Failed terra cotta tile liners. Original clay liners in Harrison’s pre-1955 housing stock have endured decades of thermal shock from fuel conversions. Tiles shift, crack, or flake—creating gaps where combustion gases can reach the chimney wall. This is a carbon monoxide risk, not a maintenance item.
• Leaks at the roofline that aren’t roof leaks. Water staining on ceilings near the chimney often gets blamed on roofing when the actual culprit is deteriorated flashing or a cracked crown diverting water behind the siding. We diagnose the source before anyone tears off shingles.
