Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict - no jargon, no pressure.

Jericho customers tell us they chose us because we explain what we’re seeing.

Most jobs complete in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. We’ve learned that in Jericho’s tight subdivisions, from the Hamlet East streets near the Jericho Turnpike corridor to the custom homes off Cantiague Rock Road, word travels fast. We plan to be in this market in thirty more years, so we act accordingly.

Our Chimney Cap & Crown Services in Jericho

Cap Installation

New cap installation in Jericho runs $280-$450 for standard single-flue models and $520-$780 for multi-flue systems. Many Jericho homes built during the 1950s-1970s suburban boom have double-flue masonry chimneys that were originally capped with a single flue cover, leaving the second flue completely exposed. We size and install Gelco and Famco caps with proper overhang and mesh screening to keep out squirrels, raccoons, and the wind-blown debris common along Nassau County’s exposed ridge lines.

Cap Replacement

Cap replacement in Jericho costs $240-$420 for direct swaps and up to $680 when the flue tile or top course of brick needs repair first. The original caps on Jericho’s tract homes were often galvanized steel that rusted through in 10-15 years, or cheap aluminum that blew off in the first nor’easter. We replace them with stainless steel or copper options from Olympia Chimney and Copperfield, sized to the actual flue count - not whatever was cheapest when the house was built.

Crown Repair

Crown repair in Jericho typically ranges $380-$650 for crack sealing and resurfacing, and $720-$1,180 for full crown rebuilds on larger or multi-flue chimneys. Nassau County’s freeze-thaw cycle is brutal on the thin mortar crowns that cap these older chimneys. Water seeps into hairline cracks, expands when it freezes, and opens gaps that let rain run straight down into the smoke chamber. We use HeatShield CrownCoat for resurfacing jobs and pour new concrete crowns with proper drip edges and slope when the original is too far gone.

Crown Coating

Crown coating is our most cost-effective preventive service in Jericho, running $280-$420 for standard residential chimneys. For chimneys with minor cracking but sound structural crowns, we apply a flexible, waterproof membrane that bridges existing cracks and prevents new water intrusion. This is especially valuable on Jericho’s 1960s-1970s split-levels where the chimney sits low on the roofline and takes direct wind-driven rain. A coated crown can add 10-15 years of service life before rebuild becomes necessary. We include before-and-after photos with every coating job.

Multi-Flue Cap

Multi-flue cap installation in Jericho ranges $520-$890 depending on chimney width and access. This is the solution we recommend most often for Jericho’s older homes. A single cap on a double-flue chimney leaves one flue open to water, animals, and downdrafts. Our custom-fabricated multi-flue caps cover all flues with a single sloped top that sheds water away from the crown, and we size them to the actual flue spacing - not a generic box from a hardware store.

Custom Cap

Custom cap fabrication for Jericho’s larger homes and architectural chimneys runs $680-$1,450. The custom homes near Cantiague Rock Road and along the Jericho Turnpike corridor often feature oversize or unusually configured chimneys that need site-measured solutions. We fabricate from stainless steel or copper with custom mesh, decorative bands, and finishes that match the home’s exterior. Lead times are typically 7-10 days, and we handle the measuring and installation in one coordinated visit.

Trusted Brands We Service in Jericho

We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. For Jericho cap-and-crown jobs, we stock Gelco stainless caps, Famco multi-flue assemblies, and Olympia Chimney components in our regional inventory, which means most replacements don’t require a second trip. When a crown needs coating, we use HeatShield CrownCoat, a flexible refractory membrane designed specifically for chimney crown resurfacing. These are the same brands specified by chimney professionals nationwide, and we don’t substitute cheaper alternatives to win a bid. The materials cost more upfront. They last.

Common Chimney Cap & Crown Problems We See in Jericho Homes

• Single-flue caps on double-flue chimneys. Jericho’s 1950s-1970s tract colonials and split-levels were built with two flues - one for the fireplace, one for the furnace or water heater - but many still carry only one cap from a long-ago repair. The open flue funnels nor’easter rain directly onto the smoke chamber and damper, accelerating rust and mortar decay.
• Gas-log retrofits hiding liner failure. Homeowners across Jericho have converted original wood-burning fireplaces to gas-log sets or inserts, but the acidic exhaust from these appliances degrades original clay tile liners faster than wood smoke ever did. A deteriorated liner can’t be detected from outside, but it shows up as poor draft, odors, or moisture stains - problems a new cap won’t solve alone.
• Freeze-thaw crown destruction. Nassau County winters oscillate across freezing for weeks at a time. Water enters crown cracks, expands, and opens them wider with every cycle. By spring, a crown that looked sound in October has separated from the brick course below, creating a channel for water straight into the flue system.
• Summer-dormant chimneys with October shock-loading. Jericho chimneys that sit unused from May through September, then fire heavily when the first cold snap hits in October or November, often reveal hidden cap, crown, and liner damage at first use. The thermal shock of that first hot fire against cold, moisture-saturated masonry opens cracks that were invisible in summer inspection.

The Jericho Cap-and-Crown Challenge: What Makes This Market Different

The Town of Oyster Bay - Jericho’s governing municipality - requires permits for liner replacements and significant chimney repairs, and inspectors actively review work in Jericho’s tight, well-watched subdivisions where neighbors routinely flag unpermitted jobs to code enforcement. Because Jericho’s 1950s-1970s tract colonials and split-levels carried original single- or double-flue masonry chimneys built under older, less stringent codes, a cap-and-crown job here often uncovers a failed clay tile flue liner that triggers the permit requirement before the crown work is even finished.

This isn’t theoretical. In the Hamlet East section of Jericho, we were called to a 1965 raised ranch where the homeowner had retrofitted a gas-log set into the original wood-burning fireplace and started noticing a musty odor and a flue that wouldn’t draft. Our tech pulled the damper, found a spalled original clay tile flue liner with deteriorated mortar joints - likely cracked by a freeze-thaw cycle and accelerated by wind-blown rain entering an uncapped flue opening - and installed a stainless DuraFlex liner with a Gelco top plate and a custom Copperfield multi-flue cap sized for the home’s second flue. We filed the Oyster Bay permit for the reline, coated the chimney crown with HeatShield CrownCoat to stop further water intrusion, and returned after inspection to clean and reseal the smoke chamber and firebox.

That sequence - cap removal revealing crown damage, crown work revealing liner failure, liner replacement triggering permit requirements - is common in Jericho. A contractor who doesn’t understand Oyster Bay’s inspection process can leave you with a job that can’t pass final inspection, or worse, a code violation complaint from a neighbor who noticed the work truck. We file permits correctly. We schedule inspections. We return to complete the job after sign-off. Done right - and we stand behind it.
