Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Cap & Crown Across Jericho
Chimney cap and crown work in Jericho runs $280-$950 depending on whether you need a standard cap install, custom fabrication, or crown rebuilding, and most jobs are completed in a single visit. If your home sits on the Jericho Turnpike corridor or in one of the older neighborhoods near Cantiague Park, the condition of your cap and crown is likely the single most overlooked factor in whether your chimney lasts another decade or starts leaking this winter.
We’ve been dispatching crews to Jericho from our New York City office for over 42 years. We know the difference between a true masonry chimney on a 1960s colonial near the Jericho Library and a factory-built zero-clearance unit hidden behind brick veneer in one of the teardown-rebuilds off Route 25. That distinction matters because the wrong cap on the wrong chimney type isn’t just ineffective - it can void your UL listing and trap dangerous heat. Call (934) 348-4832 and you’ll reach a live person, 24 hours a day.
Why Hearthstone Chimney Co. Is Jericho’s Preferred Chimney Cap & Crown Company
Jericho homeowners tend to stay put. The 1950s-1970s colonials and split-levels in the Cantiague Park area, the expanded capes near the Middle School, and the larger rebuilds along Jericho Turnpike - these are houses people raised families in and now maintain with an eye toward the next twenty years. We understand that timeline because we’ve been working here since 1984.
Our reputation in Jericho is built on documentation. Every cap and crown inspection ends with photos you can see and a plain-English verdict. No recommendations without camera evidence. No pressure to replace what can be coated or repaired. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we make it right, no paperwork and no arguing.
Most Jericho calls are answered by a live person within three rings, and our background-checked, uniformed technicians carry the parts and materials to complete most cap and crown jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Jericho
Cap Installation
New cap installation in Jericho typically costs $280-$450 for a standard single-flue stainless cap with spark arrestor, or $550-$850 for a multi-flue cap covering two or more flues. On older colonials near the Jericho Public Library, we often find original caps that were never upgraded when a second fireplace or gas insert was added - leaving one flue exposed to rain and debris while the other is overcrowded. We measure every flue, check clearances to combustibles, and spec caps from Gelco or Olympia Chimney that fit the actual flue diameter, not the nearest stock size.

Cap Replacement
Cap replacement runs $320-$580 in Jericho when the existing cap is rusted through, improperly sized, or - increasingly common in the teardown-rebuild colonials along Route 25 - the wrong manufacturer’s component for a factory-built fireplace. We remove the old cap, inspect the flue tile or chase cover beneath for hidden water damage, and install a replacement that matches the appliance’s original specification. Done right, and we stand behind it.

Crown Repair
Crown repair in Jericho costs $450-$750 for partial rebuilds of spalled concrete or mortar, or $800-$1,400 for full crown replacement on larger masonry chimneys. Jericho’s inland position in Nassau County exposes chimneys to hard freeze-thaw cycles when nor’easter moisture seeps into crown cracks, expands overnight, and pops off surface layers by spring. We see this pattern every March on the 1950s-70s colonials between Jericho Turnpike and the Northern State Parkway. Our crown repairs use professional-grade materials formulated for Long Island’s wet winters, not the fast-setting patch kits that crack again in two seasons.

Crown Coating
Crown coating is $380-$550 for most Jericho chimneys - a specialized resurfacing that seals hairline cracks and restores slope to a deteriorated crown without full demolition. It’s the right choice when the crown structure is sound but the surface is porous or cracked. We use HeatShield crown coating products, applied after wire-brush prep and a moisture-content check. The coating cures to a waterproof, slightly flexible finish that moves with the masonry through freeze-thaw cycles. For Jericho homes with multiple fireplaces and flues, crown coating can extend service life five to seven years while you plan for more extensive work.

Multi-Flue Cap
Multi-flue caps cover two or more flues with a single hood, critical for Jericho homes with original masonry chimneys that vented both an oil-fired boiler and a wood-burning fireplace. After the gas conversion wave of the 2000s-2010s, many of these chimneys now have one active flue and one abandoned liner - both needing protection from water, animals, and debris. A multi-flue cap from Copperfield or Gelco, properly sized to the chimney top, costs $650-$950 installed. We measure center-to-center flue spacing and overall chimney dimensions in the field, then fabricate or order to fit.

Custom Cap
Custom caps run $750-$1,400 in Jericho, typically for oversized masonry chimneys, chase tops on factory-built fireplaces with non-standard dimensions, or heritage homes where an off-the-shelf cap would look wrong. We were called to a rebuilt colonial off Jericho Turnpike where the homeowner’s “masonry” fireplace was actually a zero-clearance unit behind a brick veneer, and the previous cap had been screwed into the chase top with no gasket. Our tech measured the chase, ordered a custom Copperfield multi-flue cap with a spark-arrest screen sized to the factory flue collar, and sealed the crown chase edge with Gelco before reinstalling the chase cover - dropping the firebox temperature at the top of the chase by roughly 80°F on the next burn.

Trusted Brands We Service in Jericho
We stock and install professional-grade caps, crowns, and chase covers from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands that manufacture to UL standards and back their products with real warranties, not marketing promises. For Jericho customers, this means no waiting weeks for a special order from a warehouse in Ohio. Our trucks carry the common sizes for Long Island’s prevalent chimney types, and what we don’t have on the shelf, we can typically source within 48 hours from regional distributors. No builder-grade substitutes. No “it’ll work” improvisation. The cap or crown on your Jericho home gets the component it was designed for.
Common Chimney Cap & Crown Problems We See in Jericho Homes
- Cap sized for a masonry flue mounted on a factory-built chase top. On Jericho’s Route 25 corridor, the 1990s-2000s teardown-rebuilds left many homes with factory-built zero-clearance fireplaces that get capped with the wrong manufacturer’s component - often a Famco or Olympia cap spec’d for a masonry flue - so the cap seals the chase but voids the UL listing and traps heat the unit was designed to vent off.
- Original terra-cotta crown spalling through freeze-thaw cycles. Jericho’s inland Nassau County location means chimneys catch the full brunt of nor’easter-driven moisture, which freezes overnight in crown cracks and pops off surface layers by March. We flag this damage on every rooftop inspection, because a spalled crown channels water straight down the flue liner to rust the damper assembly below.
- Abandoned oil flue left uncapped or covered with a flat cap that has no draft relief. After Jericho’s oil-to-gas conversion wave, many oversized flue liners were simply left open or capped with a flat metal disc that traps condensation. The unused liner stays damp year-round, accelerating deterioration of adjacent active flues and creating musty odors that homeowners mistake for a fireplace problem.
- Multi-flue chimney with mismatched or missing caps. The 1950s-1970s colonials near Cantiague Park and the Jericho Middle School often have two or three flues serving fireplace, furnace, and maybe a long-abandoned incinerator - but only one flue capped, or caps of three different ages and conditions. Water enters the uncapped flue, freezes, and damages the shared crown structure for all.

FAQs - Chimney Cap & Crown in Jericho
Yes. Every flue needs a proper cap, including abandoned oil flues. In Jericho, we regularly find converted homes where the old oversized liner was left open or covered with a flat disc that traps condensation. That damp liner deteriorates adjacent masonry and can funnel moisture into your basement or living space. We typically recommend a multi-flue cap with draft relief for the abandoned flue, or a dedicated cap sized to the new gas appliance’s smaller liner. Call (934) 348-4832 for an exact quote - estimates are free.
The only reliable way is a Level-2 camera inspection. On Jericho’s Route 25 corridor, many 1990s-2000s teardown-rebuilds have factory-built fireplaces with brick veneer that looks identical to masonry from the street or even from the hearth. Our technicians identify the difference by inspecting the flue - a zero-clearance unit has a listed metal flue collar and specific chase-top dimensions, while true masonry has terra-cotta flue tile. We photograph what we find and explain it in plain English. Call (934) 348-4832 to schedule - estimates are free.
Jericho’s inland Nassau County location exposes chimneys to repeated freeze-thaw cycles: nor’easter moisture seeps into micro-cracks, expands when temperatures drop below 32°F, and fractures the concrete from within. Original crowns on 1950s-1970s colonials were often poured with too little slope or too much water in the mix, making them especially vulnerable. Crown coating with a flexible, waterproof formulation can extend service life significantly; full replacement with proper slope and reinforcement is the permanent fix. Call (934) 348-4832 for an exact quote - estimates are free.
Every flue needs its own termination, but they don’t all need separate caps. For Jericho homes with multiple flues on a shared chimney, we often install a single multi-flue cap that covers all openings with one hood - cleaner appearance, better protection, and no gaps where water can pool between individual caps. We measure center-to-center spacing and overall chimney dimensions in person, then fabricate or order to fit. Call (934) 348-4832 for an exact quote - estimates are free.
Sometimes, but not always. A properly sized cap with the right clearance can reduce wind-induced downdrafts, especially on Jericho homes exposed to northwesterly winter winds. However, draft problems often stem from flue sizing mismatches - common in oil-to-gas conversions where the oversized original liner creates sluggish draw - or from blocked flues, damaged dampers, or negative pressure from modern HVAC systems. We diagnose the actual cause with a camera inspection before recommending any cap as a solution. Call (934) 348-4832 for an exact quote - estimates are free.
