Why Hearthstone Chimney Co. of New York City Is Old Tappan’s Preferred Chimney Cap & Crown Company
We’ve worked in Bergen County for over 42 years, and Old Tappan Chimney Cleaning & Sweep is something we’ve documented hundreds of times for this area’s particular mix of affluent custom homes and aging masonry. Our Level-2 camera inspections end with photos you can see and a plain-English verdict - no guesswork, no scare tactics.
Because Old Tappan sits directly on the NJ/NY state line, many residents have hired chimney crews from Rockland County or Manhattan, only to have local building officials flag the work later. NJ law requires chimney sweeps to carry NJ Home Improvement Contractor registration, and we’ve been called in more than once to correct liner installations done by unlicensed NY-side operators unfamiliar with New Jersey code. We carry the proper registration, pull permits when required, and document everything.
Our technicians are background-checked and uniformed, and most jobs are completed in a single visit. We offer no-hassle upfront pricing - the number on the estimate is the number on the invoice. The 90-Day Done Right Promise backs every job in writing: if it’s not right, we come back, no arguing.

Our Chimney Cap & Crown Services in Old Tappan
Crown Repair & Crown Coating
Old Tappan’s 1960s-1980s custom colonials often have concrete crowns poured over original terra cotta flue liners now 35-65 years old. Decades of thermal cycling - heating to 400°F+ during winter fires, then freezing when the flue cools - hairline cracks the crown and lets water seep behind the liner. On a 1968 split-level on Chestnut Ridge Road, we found exactly this during Chimney Repair in Old Tappan: a crown with a hairline crack allowing water to seep into the masonry behind the terra cotta flue liner. We applied a HeatShield crown coating to seal the crack and installed a custom copper multi-flue cap to prevent future moisture intrusion from nor’easters. Crown coating in Old Tappan typically runs $285-$450 for a standard single-flue crown. Full crown rebuilds start around $620.

Custom Cap & Multi-Flue Cap Installation
Multi-fireplace homes are the norm in Old Tappan, not the exception. Many properties have two or three working flues, often with decorative fireplaces on the main level and a basement utility flue from an oil-to-gas conversion. Standard big-box caps don’t fit these configurations. We fabricate custom multi-flue caps measured to your exact flue spacing and roof pitch, using Copperfield and Gelco materials rated for coastal-exposure wind loads. Custom multi-flue caps in Old Tappan typically range $480-$780 installed, depending on metal type and spark-arrestor specifications.

Cap Replacement
The original galvanized caps on Old Tappan’s 1970s and 1980s homes have often rusted through after 30+ years of nor’easter exposure. A rusted cap isn’t just unsightly - it allows rain directly onto the crown, accelerating the freeze-thaw damage that destroys masonry below. We replace failed caps with properly sized stainless steel or copper units, matched to your flue diameter and local wind exposure. Standard cap replacement in Old Tappan runs $185-$340.

Cap Installation on Previously Uncapped Flues
We regularly find uncapped flues in Old Tappan, especially on homes where oil-to-gas conversions left secondary flues abandoned or where previous owners simply never installed protection. An uncapped flue is an open hole in your roof. Squirrels, raccoons, and rain enter freely. First-time cap installation with proper sizing and screening runs $220-$395.

Trusted Brands We Service in Old Tappan
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. For crown coatings, we use HeatShield’s cerfractory formula, rated to 2900°F and specifically designed to bond with aging concrete crowns. Our custom and multi-flue caps come from Copperfield and Gelco, with stainless steel mesh spark arrestors that hold up to Bergen County’s wind-driven rain and ice. We stock common sizes and fittings locally, so most Old Tappan customers don’t wait for special orders. DuraFlex components handle the venting connections on converted gas appliances. Every material choice is documented in your post-inspection report, with photos.
Common Chimney Cap & Crown Problems We See in Old Tappan Homes
- Crown cracking from thermal cycling. Old Tappan’s 1955-1990 colonials have original terra cotta flue liners now 35-65 years old. The liner expands when heated, contracts when cooled, and eventually cracks the concrete crown poured around it. We catch this early with camera inspection before water reaches the smoke chamber.
- Water infiltration through degraded mortar joints. Old Tappan’s position in the lower Hudson Valley exposes chimneys to nor’easter-driven moisture worse than inland Bergen County towns. Wind-driven rain finds every open joint on exposed exterior stacks, and freeze-thaw cycles pop mortar out within a few seasons.
- Improper multi-flue caps after oil-to-gas conversions. Many Old Tappan homes converted from oil to gas heating in the 2000s-2010s, leaving original oversized clay-tile flue liners that now vent high-efficiency gas appliances. The wrong cap size creates dangerous condensation and creosote buildup, or leaves flues uncapped entirely, causing downdrafts and animal entry.
- NY-side crews with no NJ registration. Because residents frequently hire contractors from across the state line, we’ve inspected work done by unlicensed NY crews who didn’t understand NJ venting codes for gas appliances. The caps were installed, but the clearances and liner connections were wrong.

FAQs - Chimney Cap & Crown in Old Tappan
Standard caps are built for single flues with standard spacing, but Old Tappan’s custom colonials frequently have two or three flues with irregular spacing, varying heights, and mixed decorative and utility functions. A custom multi-flue cap is fabricated to your exact flue layout, with proper screening and clearances for each flue type. Call (855) 950-3861 and we’ll measure on-site - estimates are free.
Yes. NJ law requires chimney sweeps to carry NJ Home Improvement Contractor registration, and work done by unlicensed out-of-state crews is not recognized by local building officials. We’ve been called to correct installations where NY-side contractors used wrong clearances for gas appliance venting or failed to document liner compatibility. We carry proper NJ registration and provide permit-ready documentation.
We first perform a Level-2 camera inspection to confirm the liner itself is structurally sound - coating a cracked liner traps moisture and accelerates deterioration. If the liner passes, we grind the crown surface, apply HeatShield’s bonding layer, then trowel the cerfractory coating to a minimum ¼-inch thickness. The job takes 3-4 hours and carries our 90-Day Done Right Promise. Most Old Tappan crown coatings run $285-$450.
Stainless steel or copper with a minimum 5/8-inch mesh spark arrestor, fabricated with reinforced corners and proper overhang to shed wind-driven rain. We size the cap for your specific flue diameter and local wind exposure, not a generic chart. For homes with multiple flues, a custom multi-flue cap with integrated skirt prevents the blow-under that sends rain down abandoned flues during coastal storms.
Hairline cracks under 1/16 inch with no spalling or exposed rebar are candidates for crown coating if the underlying liner is sound. Wider cracks, crumbling edges, or cracks that have opened after previous patching mean the crown is failing structurally and needs rebuild. We document the condition with photos and give you a straight recommendation - no upsell, no deferral of necessary work. The 90-Day Done Right Promise covers either option. Call (855) 950-3861 for an exact assessment.
