We’ve been working in the 10504 ZIP code and surrounding northern Westchester hills for decades.

Why Hearthstone Chimney Co. Is North Castle’s Preferred Chimney Repair Company
North Castle homeowners don’t have patience for callbacks or excuses. Neither do we.
Our reputation here was built one job at a time, mostly through neighbors telling neighbors on streets like Bedford Road and Whippoorwill Road. We don’t chase reviews, but the ones we have from North Castle customers consistently mention the same things: we show up when we say, we explain what we found in plain English, and we leave the work area cleaner than we found it.
Response time to North Castle is typically same-day or next-day during the busy season, and we keep our scheduling tight because we know most of our customers are burning wood heavily through those cold inland winters and need Chimney Cleaning & Sweep - North Castle they can count on. The hilly terrain and winding driveways off Route 22 don’t slow us down; our technicians know the local roads well enough to arrive with time to spare.
What separates us from the one-truck operators and price-cutting chains is simple accountability. Every inspection ends with photos you can see and a written verdict you can understand. Every repair is backed by our 90-Day Done Right Promise in writing, no arguing. And every call is answered by a live person, not a voicemail maze.
Our Chimney Repair Services in North Castle
Mortar Repointing
The freeze-thaw cycles hit North Castle harder than coastal Westchester. Water seeps into mortar joints, expands overnight when temperatures drop below 20 degrees, and by spring you’ve got gaps deep enough to slide a coin into. We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade mortar formulated for our climate. Most North Castle repointing jobs run $850-$1,800 for a standard two-flue chimney.

Spalling Brick Repair
Spalling, the flaking and crumbling of brick faces, is epidemic in North Castle’s 1980s-era colonials where original construction used softer brick grades or where waterproofing was never applied. On homes near the Armonk reservoir area, we’ve replaced entire courses of spalled brick while preserving the original corbeled detailing that gives these chimneys their character. Individual brick replacement starts around $450; larger surface rebuilds range $1,200-$2,400.

Chimney Waterproofing
North Castle’s heavier snowfall and spring thaw cycles make waterproofing essential, not optional. We apply vapor-permeable sealers from professional-grade lines that let the chimney breathe while blocking water intrusion. A typical waterproofing treatment for a North Castle masonry chimney runs $650-$1,100 and carries a 10-year performance expectation when properly maintained.

Flashing Repair
The combination of steep-pitched roofs common in North Castle’s hilly terrain and the aggressive spring thaw creates perfect conditions for flashing failure. We fabricate and install custom step flashing and counterflashing, sealed with high-temperature compounds that flex through temperature swings. Flashing repairs in North Castle typically cost $550-$1,400 depending on roof pitch and accessibility.

Trusted Brands We Service in North Castle
We stock parts and materials from Olympia Chimney, Famco, and Copperfield on every truck serving North Castle, which means most repairs don’t wait for a second trip. These are the brands we specify because they hold up to the thermal stress and moisture exposure that northern Westchester chimneys endure. When we arrive at your home on Bedford Road or in the back roads off Long Ridge Road, we come prepared to finish the job that day, not to diagnose and reschedule.
Common Chimney Repair Problems We See in North Castle Homes
- Crown cracks from freeze-thaw aggression. North Castle’s inland elevation means more nights below 20 degrees than lower Westchester towns. Water trapped in crown concrete expands, splits the surface, and opens a direct path to the flue liner. We see this on roughly half the 1980s-era homes we inspect.
- Original clay-tile liner deterioration. Those IBM-era colonials with two or three fireplaces often have clay liners that have survived 35 to 45 heating seasons. The tiles crack, the mortar between them erodes, and suddenly you’ve got gaps that let combustion gases leak into wall cavities.
- Failed factory-built fireplace fireboxes. A significant share of the large Armonk-area homes built or renovated in the 1980s contain zero-clearance metal fireplaces now well beyond their 20-25 year design lifespan. We routinely arrive for what the homeowner thinks is a routine cleaning and find rusted fireboxes and failed refractory panels that legally require full unit replacement before safe use.
- Spring flashing leaks after heavy snow seasons. The melt-off from North Castle’s heavier snowfall finds every gap in roof-to-chimney flashing. By March, we’re fielding calls from homeowners who’ve spotted water stains on ceiling drywall near the fireplace.

Here’s what chimney repair costs in North Castle’s market, based on jobs we’ve completed in the 10504 area over the past two years:
| Service | Typical Range |
|---|---|
| Mortar repointing (standard chimney) | $850 - $1,800 |
| Spalling brick repair (partial) | $450 - $1,200 |

What moves you within these ranges? Roof pitch and accessibility matter on North Castle’s hillside lots. Decorative masonry with corbeled brickwork or custom caps takes more time to match properly. And the condition of the underlying structure, if water has been penetrating for multiple seasons, can reveal surprises once we open the wall.
