Call (732) 507-9649

We’ve worked on chimneys in Lyndhurst long enough to recognize the pattern: these 1930s-1960s brick stacks were built for oil heat, and the gas conversions that followed left oversized flues running cool and wet. Acidic condensate attacks crowns from above while Passaic River flood-plain moisture wicks up from below. It’s a one-two punch you won’t find in a textbook written for Arizona or even for newer Bergen County construction. Our Chimney Cap & Crown team documents what we find with photos you can see, gives you a plain-English verdict, and stands behind the repair with our 90-Day Done Right Promise in writing.

Our reputation in Lyndhurst rests on documentation. Every Level-2 camera inspection ends with photos and a written verdict. When we tell you a crown is cracked through to the flue liner, you’ll see the crack. When we recommend a multi-flue cap over individual flue caps, we’ll show you why the wind exposure off the Passaic makes the difference. No surprises on the bill. No arguing if something needs correction - our 90-Day Done Right Promise covers it in writing.

Dispatch and scheduling are coordinated from our New York City office, but our crews live and work in Bergen County. They know that a nor’easter hits the river-facing slopes harder than the ridge above Kingsland Avenue, and they know which Lyndhurst neighborhoods sit in the flood zone where efflorescence and damper corrosion show up year after year.

Our Chimney Cap & Crown Services in Lyndhurst

Crown Repair

Crowns on Lyndhurst’s original oil-era chimneys are often only 1-2 inches thick, poured as an afterthought by builders who assumed hot oil exhaust would keep the stack dry. After gas conversion, those thin crowns crack along the flue from freeze-thaw cycles and internal acid attack. We chip out the failed concrete, build forms with proper slope and drip edges, and pour a new crown at least 4 inches thick at the flue, sloped to shed water. On a Ridge Road colonial near the Passaic, our tech found a chimney crown cracked in a spiderweb pattern after a winter of freeze-thaw, with a displaced single-flue cap sitting crooked from a nor’easter gust. We chipped out the failed crown, poured a new overhanging crown with a drip edge, and set a Gelco stainless multi-flue cap with a spark screen - the homeowner’s ceiling stain stopped spreading and the flue liner finally stayed dry.

Cap Replacement

Storm-driven wind off the Passaic River shears the mounting screws on lightweight caps, leaving displaced or missing caps that expose the flue liner to direct rain and animals. We replace failed caps with professional-grade stainless units from Gelco or Olympia Chimney, sized to the flue and secured with proper tapcon anchors or masonry screws, not the thin sheet-metal straps that fail in Lyndhurst’s wind. A cap replacement in Lyndhurst typically runs $280-$450 installed, depending on flue count and access.

Multi-Flue Cap Installation

Many Lyndhurst colonials have multiple flues - one for the furnace, one for our Fireplace Services in Lyndhurst to address, sometimes a third for a long-removed oil burner. Individual flue caps leave gaps where wind-driven rain enters, and they’re easier to displace. A multi-flue cap covers the entire chimney top, protecting the crown and all flues with a single anchored unit. We measure on site, fabricate from stainless steel with a spark screen, and set it with a proper overhang. For homes near the river with chronic wind exposure, this is often the only solution that lasts.

Crown Coating

For crowns with early-stage cracking but sound structural integrity, we apply HeatShield crown coating - a flexible, waterproof sealant that bridges hairline cracks and prevents water penetration. It’s not a substitute for a failed crown, but on a 1960s Cape Cod on Stuyvesant Avenue with minor surface cracking, it can add five to seven years of protection at roughly half the cost of a rebuild. We’ll show you the photos and tell you honestly which category you’re in.

Trusted Brands We Service in Lyndhurst

We stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands that hold up to Lyndhurst’s freeze-thaw cycles and Passaic River humidity, not the builder-grade substitutes you’ll find at big-box stores. Because we carry common cap sizes and crown repair materials on our trucks, most Lyndhurst jobs don’t wait for parts. A standard cap replacement or crown coating is done in one visit. Custom-fabricated multi-flue caps for oversized historic chimneys typically ship within a week, and we schedule installation the day they arrive.

Common Chimney Cap & Crown Problems We See in Lyndhurst Homes

• Spiderweb crown cracks after freeze-thaw. Lyndhurst’s thin original crowns absorb moisture from both condensing flue gas and flood-plain wicking, then crack in the first hard freeze. The pattern looks like a dropped eggshell, and water runs straight into the smoke chamber.
• Caps displaced or missing after nor’easter winds. Storms coming off the Passaic generate sustained winds that shear the screws on poorly anchored caps. Homeowners often don’t notice until water stains appear on the ceiling below.
• Flashing failures on low-slope 1960s Cape Cod roofs. The gentle pitch common in Lyndhurst’s Cape Cods lets wind drive rain uphill at the chimney-roof junction. The stain shows up near the chimney, but the cap is fine - it’s the step flashing or counterflashing that failed.
• White mineral crust and rotted dampers in flood-zone homes. Technicians working near the Passaic River sections of town regularly find fireboxes with a distinctive white mineral crust along the lower courses of brick - efflorescence from historic floodwater absorption - combined with a rotted-out damper blade, damage homeowners almost always attribute to a roof or flashing leak rather than the water that rose from below.
