We’ve been working on East Hills chimneys for over 42 years, since back when most of these homes were barely twenty years old. We know the post-war colonials along I.U. Willets Road, the split-levels near the East Hills Park, and the Tudors tucked along Harbor Hill Road. Every one of them was built with a masonry fireplace as a centerpiece, and every one of those chimneys is now 50-70 years old. That age shows. Salt-laden moisture drifts down from Long Island Sound just a few miles north, and it attacks mortar joints and brick faces faster than you’ll see in towns further inland. We’ve watched it happen season after season.
Our Chimney Repair team carries the materials to fix most problems on the spot - DuraFlex liners, HeatShield resurfacing compound, Gelco crown sealant, professional-grade flashing from Famco and Copperfield. We don’t make two trips when one will do.

Our Chimney Repair Services in East Hills
Chimney Rebuilding
Some East Hills chimneys have simply reached the end of their service life. The combination of original 1950s-70s construction, decades of freeze-thaw cycling, and salt-air corrosion leaves the outer structure compromised. We rebuild from the roofline up or perform partial rebuilds of damaged courses, matching existing brick where possible and using Copperfield components for structural integrity. A full rebuild in East Hills typically runs $3,200-$4,500; partial rebuilds start around $1,800. We recently rebuilt a severely spalled chimney on a 1968 bi-level near East Hills Park - the north face had deteriorated from years of direct coastal exposure.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic on East Hills’s older chimneys. Salt-laden air from Long Island Sound penetrates the masonry, then winter freeze-thaw cycles pop the surface off. North-facing chimneys suffer worst. We cut out damaged brick and repoint with color-matched mortar, or rebuild sections where the damage is too deep for spot repair. Spalling brick repair in East Hills typically costs $650-$1,400 depending on area and accessibility. Left untreated, spalling exposes the inner structure to accelerated decay. We catch it early with our Level-2 camera inspections.
Flashing Repair
Chimney flashing is the metal seal where your chimney meets the roof, and it’s a common failure point in East Hills. Coastal humidity corrodes galvanized flashing faster than inland climates, and the village’s mature trees drop debris that traps moisture against the seal. We install professional-grade flashing from Famco, sealed with proper counter-flashing techniques that shed water rather than trapping it. Flashing repair in East Hills runs $450-$950. We also inspect the surrounding roof membrane - water stains on your ceiling often originate here, not in the flue itself.
Mortar Repointing & Tuckpointing
The mortar joints in a 60-year-old East Hills chimney are often eroded to powder. We grind out failed joints to proper depth and repoint with high-bond mortar formulated for coastal exposure. Tuckpointing - the cosmetic technique of matching existing joint profiles - restores the chimney’s appearance while sealing out water. Mortar repointing in East Hills typically costs $850-$2,100 for a standard single-flue chimney. Multi-flue systems common in larger East Hills colonials run toward the higher end.
Chimney Waterproofing
After repair, we apply breathable waterproofing sealant that blocks liquid water while allowing vapor to escape. This is critical in East Hills’s humid coastal climate, where trapped moisture accelerates every form of masonry decay. Waterproofing a typical East Hills chimney runs $380-$650 and extends the life of brick and mortar by years.

Trusted Brands We Service in East Hills
We stock professional-grade materials from the brands that chimney professionals actually trust: DuraFlex stainless steel liners for relining jobs, HeatShield resurfacing compound for restoring damaged flue surfaces, Gelco crown sealants for waterproofing, and Famco and Copperfield components for flashing and structural repairs. We don’t substitute builder-grade materials to shave a few dollars. For East Hills customers, this means faster turnaround - most parts are on our trucks already, and we don’t wait for special orders to complete your job. The right material for the repair, installed once, done right.
Common Chimney Repair Problems We See in East Hills Homes
- Salt-laden air from nearby Long Island Sound accelerates spalling of brick and mortar joints, especially on north-facing chimneys. The coastal exposure here is real and measurable. Chimneys that would last decades inland show surface damage in half the time. We inspect for this specifically on every East Hills call.
- Freeze-thaw cycles during nor’easters cause premature cracking of clay flue tiles and chimney crowns. Water enters micro-cracks, expands when frozen, and widens the damage with every cycle. East Hills sees more of these events than southern Nassau County. Crown cracks left untreated become crown collapses.
- Oversized unlined gas flues from oil-to-gas conversions lead to draft inefficiency and carbon monoxide risks. This is the signature East Hills problem. In the 1980s and 90s, homeowners converted from oil to gas but frequently left the original large clay flues unlined for the new appliances. The resulting flue is too large for efficient gas appliance draft, and condensation accelerates liner deterioration. Nassau County home inspectors flag this routinely during real estate transactions, driving urgent relining jobs.
- Multi-flue chimneys serving fireplace, furnace, and water heater require separate inspection of each flue. Many affluent East Hills homes have complex chimney systems. A fireplace flue can be clean while an adjacent furnace flue is deteriorated - or vice versa. Our Level-2 camera inspection documents each flue independently with photos you can see.
We recently repaired a cracked crown and unlined gas flue on a 1962 colonial on Piccadilly Lane. The original clay liner had spalled from salt-laden coastal moisture, and the unlined gas flue failed a home inspection. We installed a DuraFlex stainless steel liner and sealed the crown with Gelco waterproofing. One visit. The homeowner had her clearance in time for closing.

FAQs - Chimney Repair in East Hills
Yes, almost certainly. The oversized clay flues left behind after oil-to-gas conversions in the 1980s and 90s are too large for efficient gas appliance draft and create condensation problems that accelerate deterioration. Nassau County inspectors flag unlined gas flues as a code deficiency during home sales. We install DuraFlex stainless steel liners sized precisely for your appliance. Call (855) 950-3861 for a free inspection and exact quote.
Every year, without exception. The salt-laden coastal air, repeated freeze-thaw cycles, and heavy winter fireplace use common on the North Shore accelerate wear beyond what national averages suggest. Annual Level-2 camera inspection catches spalling, liner cracks, and crown damage before they become rebuilds. Our $89 Seasonal Tune-Up includes a full inspection. Call to schedule.
Brown stains are almost always rust from corroded flashing or a deteriorated chimney cap, or efflorescence from water migrating through compromised mortar joints. In East Hills, coastal humidity accelerates metal corrosion and salt infiltration worsens the staining. The source matters - rust indicates metal failure, while efflorescence signals water penetration into the masonry itself. We photograph the stain source and explain exactly what you’re seeing. Free estimates: (855) 950-3861.
Yes. Coastal humidity corrodes galvanized flashing faster than inland climates, and East Hills’s mature tree canopy traps debris against the chimney-roof junction, holding moisture in place. We install professional-grade Famco flashing with proper counter-flashing to shed water, and we inspect the surrounding roof membrane as part of every flashing repair. Most East Hills flashing repairs are completed in a single visit.
Absolutely. Each flue is an independent venting system with its own liner, its own draft characteristics, and its own pattern of wear. In East Hills’s multi-flue chimneys - common in larger colonials serving fireplace, furnace, and water heater - we’ve found one flue pristine while another was actively dangerous. Our Level-2 camera inspection documents each flue separately with photos and a plain-English verdict for each. No shortcuts. Call (855) 950-3861 to schedule.
