Hollis sits in southeastern Queens, ZIP 11423, just inside the Nassau County line. That inland position matters. Without the temperature buffer of waterfront neighborhoods, Hollis sees harder freeze-thaw cycles every winter. Water seeps into crown mortar, expands, contracts, and cracks it open. Meanwhile, most chimneys here were built for coal furnaces and later converted to oil, leaving flues that don’t match modern appliances. The result: acidic condensate rises, attacks metal caps, and degrades crown concrete from above and below simultaneously. We’ve been repairing this specific damage pattern in Hollis for over 42 years.
Why Hearthstone Chimney Co. of New York City Is Hollis’s Preferred Chimney Cap & Crown Company
We’ve worked on chimneys along Hillside Avenue, Francis Lewis Boulevard, and the quieter blocks between - enough to recognize a Hollis two-family chimney by its shared flue configuration before we even set up the ladder. That local knowledge saves time and prevents misdiagnosis.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. In Hollis, where many homes have passed through multiple owners and contractors, we often find documentation gaps from Nassau-licensed work that didn’t account for NYC DOB and FDNY requirements. We flag those issues before they surface during a sale or insurance inspection.
Calls are answered by a live person 24 hours a day, 7 days a week - not a voicemail, not a callback queue. Our background-checked, uniformed technicians arrive when we say we will, and most Hollis jobs finish in one visit. The 90-Day Done Right Promise covers everything in writing: if it’s not right, we come back. No arguing, no paperwork chase.
Our Chimney Cap & Crown Services in Hollis
Crown Repair
Crown repair in Hollis usually costs $450-$780. The typical Hollis chimney crown is poured concrete or mortar wash over brick, exposed to decades of freeze-thaw cycling without proper overhang or drip edge. We remove deteriorated material down to sound substrate, form a new crown with proper slope and overhang, and seal it with professional-grade crown coating. For 1930s brick chimneys with spalling faces - common near Hollis’s older blocks - we assess whether the brick beneath can support a new crown or needs rebuilding first. Done right, and we stand behind it.

Custom Cap Fabrication & Installation
Standard galvanized caps fail fast in Hollis. The combination of acidic condensate from oversized oil-conversion flues and coastal humidity eats through them in 5-7 years. We fabricate custom caps from stainless steel and copper, measured to your exact flue configuration. Last spring we replaced a rusted-through multi-flue copper cap on a 1930s Tudor-style two-family on 199th Street in Hollis. The original cap had deteriorated from years of acidic condensate attacking the copper seams; we installed a custom-fit DuraFlex stainless-steel multi-flue cap with a sealed crown coating to protect the shared flues from further weather intrusion. Custom cap installation in Hollis runs $380-$650 for single flue, $520-$890 for multi-flue.

Cap Replacement
When your cap is missing, improperly sized, or corroded through, water enters the flue directly. In Hollis’s two-family configurations, that often means water dripping onto two separate boiler connections. We measure flue openings precisely, account for draft requirements of your heating system, and install caps with proper screen height to prevent blockage while allowing adequate venting. Cap replacement in Hollis: $280-$480 for standard stainless, $420-$680 for custom multi-flue.

Crown Coating
For crowns with minor cracking but sound structure, crown coating extends service life 5-10 years at roughly half the cost of rebuild. We use HeatShield and professional-grade elastomeric coatings formulated for crown surfaces, not generic masonry sealers. In Hollis, where freeze-thaw opens hairline cracks every winter, this preventive treatment pays for itself. Crown coating: $340-$520.

Trusted Brands We Service in Hollis
We stock caps, crowns, and repair materials from DuraFlex, HeatShield, and Famco - brands that hold up to Hollis’s specific conditions. DuraFlex stainless multi-flue caps handle the acidic condensate that destroys standard galvanized units. HeatShield crown coatings flex with thermal expansion instead of cracking through freeze-thaw cycles. We don’t substitute builder-grade materials to cut costs. The part we specify is the part we install. For Hollis customers, that means faster turnaround - no waiting on special orders - and repairs that last.
Common Chimney Cap & Crown Problems We See in Hollis Homes
- Freeze-thaw cycling cracks crown mortar and spalls brick. Hollis’s inland Queens location sees repeated temperature swings across 32°F each winter. Water enters microscopic cracks, freezes, expands, and widens them. By spring, the crown is shedding pieces and the cap sits loose on a crumbling base.
- Acidic condensate from oil-conversion flues destroys standard caps. Most Hollis chimneys were built for coal and never properly relined for oil. The resulting condensate is corrosive enough to eat through galvanized steel in 5-7 years. We see this on nearly every 1920s-1940s home in 11423.
- Two-family chimney structures have poorly integrated cap seals. When a single chimney serves two separate boiler connections, the cap must seal multiple flue openings without compromising draft. Amateur installations often leave gaps at the flue-to-cap interface where debris and moisture bypass the cap entirely.
- Nassau-licensed contractors leave compliance gaps. Because Hollis sits just inside the NYC line, some homeowners have had work done by Nassau contractors unfamiliar with NYC DOB and FDNY requirements. Unpermitted liner inserts and non-compliant appliance connections surface during sales or insurance inspections - sometimes years later.

FAQs - Chimney Cap & Crown in Hollis
Most Hollis chimneys were built for coal furnaces and later converted to oil without proper relining, producing acidic condensate that corrodes standard galvanized caps in 5-7 years. Combined with harder freeze-thaw cycling from Hollis’s inland position, caps and crowns deteriorate faster than in waterfront Queens neighborhoods with milder temperature swings. We specify stainless or custom-fabricated caps for Hollis homes, and we back every installation with our 90-Day Done Right Promise. Call (855) 950-3861 for a free inspection and exact quote.
Probably. Most two-family homes in Hollis have a single chimney structure with separate flues for each unit’s boiler or furnace. A single cap covering multiple flues prevents water intrusion at the shared crown while maintaining proper draft for each appliance. We measure your flue spacing and draft requirements on site, then fabricate a custom multi-flue cap if needed. Multi-flue cap installation in Hollis runs $520-$890. Call (855) 950-3861 to schedule a free evaluation.
For spalling brick, we first assess whether the brick faces can be salvaged or whether the crown has deteriorated far enough to require partial rebuild. When the brick is structurally sound, we remove failed crown material, repair spalled faces with compatible mortar, then pour a new sloped crown with proper overhang and seal it with HeatShield crown coating. Full crown rebuild with spall repair in Hollis typically runs $680-$1,100. We’ll give you a plain-English verdict with photos so you can decide. Estimates are free - call (855) 950-3861.
Crown repairs that don’t alter the chimney structure or appliance connections generally don’t require permits, but any work involving liner replacement, flue modification, or appliance reconnection does. Because Hollis sits at the NYC-Nassau border, we’ve found chimneys with unpermitted Nassau-licensed work that doesn’t comply with NYC Mechanical Code. We document our findings and advise when permits are needed. For a clear answer on your specific chimney, call (855) 950-3861 - estimates are free and include a compliance assessment.
A properly sized cap maintains at least 5 inches of clearance above the flue opening and allows adequate free area for venting - typically equal to or greater than the flue area. In Hollis’s oil-conversion chimneys, oversized flues often get capped with standard sizes that don’t account for the extra volume, causing draft problems and condensate buildup. We measure flue dimensions, check draft performance, and specify the correct cap size for your system. Cap sizing evaluation is included in our free Hollis estimates. Call (855) 950-3861 to schedule.
