We’ve worked on North Hills chimneys for decades. The village’s estate homes, many built between the 1940s and 1970s along streets like Saddle Rock Lane and Shelter Rock Road, present repair challenges you won’t find in standard suburban construction. Multiple flues. Original clay liners. Copper flashing that’s weathered sixty years of salt air. These aren’t problems for a general handyman. They’re specialized work, and we do it right - then we stand behind it.
Why Hearthstone Chimney Co. of New York City Is North Hills’s Preferred Chimney Repair Company
North Hills homeowners know the difference between a contractor who shows up and one who shows up prepared. For over 42 years, we’ve built our reputation in villages like this by documenting every inspection with photos our customers can see, delivering a plain-English verdict, and pricing every job upfront. No surprises on the bill. The number on the estimate is the number on the invoice.
Our North Hills customers tend to have lived in their homes for twenty-plus years. They’ve seen contractors come and go. They remember the ones who didn’t return calls, who left messes, who promised warranties they wouldn’t honor. We answer the phone with a live person 24 hours a day, 7 days a week - not a voicemail, not a callback queue. Our technicians are background-checked, uniformed, and trained to complete most repairs in a single visit. And every job is backed by our 90-Day Done Right Promise: in writing, no arguing. If it’s not right, we come back.
We know the local conditions that damage North Hills chimneys. The salt-laden air from Long Island Sound and the Atlantic accelerates spalling and mortar erosion faster than in inland Nassau County. The freeze-thaw cycles after nor’easters punish crown masonry. And many of these estate chimneys have never had a proper Level-2 camera inspection - the kind that reveals what you cannot see from the ground.
Our Chimney Repair Services in North Hills
Mortar Repointing
The multi-flue chimney stacks common in North Hills estates were built with mortar formulas from the 1950s-1970s that simply don’t hold up to decades of coastal weather. We grind out deteriorated joints to proper depth and repoint with color-matched, professional-grade mortar that bonds correctly with the original brick. On a recent job on Saddle Rock Lane, we repointed the crown of a 4-flue chimney where freeze-thaw had opened gaps wide enough to slide a pencil through. Done right - and we stand behind it.
Spalling Brick Repair
Salt-laden air from nearby waterways strips the hard face off North Hills brick faster than you’d expect. Once spalling starts, water penetrates the soft inner core and the damage accelerates. We remove spalled units, source matching brick where possible, and rebuild with proper bond patterns. For estates where original brick is no longer manufactured, we’ll show you the closest match and let you decide. Photos you can see, a plain-English verdict.
Chimney Waterproofing
Waterproofing a North Hills chimney isn’t a spray-and-go job. The large surface areas and complex crown geometries of estate chimneys require breathable, vapor-permeable sealers that won’t trap moisture inside the masonry. We use professional-grade formulations from Copperfield and HeatShield, applied after all necessary repairs are complete. Waterproofing without fixing the underlying cracks or failed mortar is a waste of your money. We won’t sell it that way.
Flashing Repair
Many North Hills homes have custom copper flashing that’s sixty years old and counting. Original step flashing, counter-flashing, and cricket configurations on these large chimneys were often built to standards that predate modern codes. We fabricate and install replacement flashing that integrates with your existing roofing - or we can specify complete custom copper work where the original has reached end of life. No builder-grade substitutes.

Common Chimney Repair Problems We See in North Hills Homes
- Gas insert chimneys with cracked clay liners. Many North Hills fireplaces were converted to gas in the 1980s-90s but kept their original oversized masonry flues. Owners assume “it’s not wood-burning anymore, so it’s fine.” It’s not. Undersized flues for gas appliances create draft problems and carbon monoxide risk that a Level-2 inspection will catch.
- Uneven mortar failure on multi-flue stacks. Chimneys with three or four flues experience differential settling and weathering. One side looks fine while the other has joints crumbling. Water finds the weak point and leaks into wall cavities, often damaging custom interior finishes before anyone notices the stain.
- Spalling accelerated by salt air. North Hills’s position between Long Island Sound and the Atlantic exposes chimneys to corrosive salt spray that inland communities don’t face. Brick faces flake off faster here. Waterproofing and timely repointing are preventive maintenance, not cosmetic luxuries.
- Original terra-cotta liners past service life. Clay tile liners in 50-80 year-old chimneys have survived thousands of heating cycles and freeze-thaw events. They crack. They shift. They create gaps that let combustion gases leak into the structure. Replacement with DuraFlex stainless or proper relining isn’t optional once deterioration reaches a threshold.

FAQs - Chimney Repair in North Hills
Yes - gas inserts vent combustion gases through the original flue, and if that clay liner is cracked or the flue is improperly sized for the appliance, carbon monoxide can leak into your home. We inspect gas-converted fireplaces with the same Level-2 camera protocol as wood-burning units. Many North Hills estates have this exact configuration, and we’ve found dangerous liner conditions that the homeowner had no idea existed. Call (855) 950-3861 to book an inspection - estimates are free.
Most North Hills chimneys need repointing every 25-40 years, but salt-air exposure and freeze-thaw cycling can shorten that interval. We recommend a professional evaluation every five years once your chimney passes the fifty-year mark. Catching mortar failure early prevents the far more expensive rebuild that follows water intrusion. We’ll be there when we say.
We can repair, patch, or replace copper flashing to match original profiles on vintage North Hills chimneys. Our technicians fabricate custom pieces on site when standard stock won’t fit the original configuration. We recently replaced copper flashing on a 1950s estate where the original had thinned to paper-like fragility. Photos, plain-English verdict, fixed price - that’s how we work.
Waterproofing alone won’t stop spalling once the brick face has failed - the damage is structural. We replace spalled units first, then waterproof the repaired surface to prevent recurrence. In North Hills’s salt-air environment, skipping either step means you’ll be dealing with the same problem again in a few seasons. A square deal: no surprises on the bill.
Yes - we perform color-matched tuckpointing that preserves the original aesthetic of estate masonry while restoring structural integrity. For North Hills homes where architectural character affects property value, this matters. We match mortar color and joint profile to existing work, not to a standard spec sheet. The repair should be invisible. Call (855) 950-3861 and we’ll show you examples from nearby work.
