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 Repair Across Lyndhurst
Chimney repair in Lyndhurst typically runs $450-$2,800 depending on scope, with most standard mortar repointing and flashing jobs completed in a single visit. We dispatch crews to Lyndhurst daily from our metro-area office, and a live person answers our phones at (732) 507-9649 every hour of every day. Lyndhurst’s dense neighborhoods of 1930s-1960s brick colonials and Cape Cods - from the Passaic River edge near Riverside Avenue up through the Kingsland section along Ridge Road - present chimney problems we know by sight: flood-wicked dampers, gas-conversion liner damage, and freeze-thaw mortar failure that newer towns simply don’t replicate.

We’ve been answering calls with a live person for over 42 years, and that steady presence matters to homeowners who’ve been burned by contractors who vanished. Our Chimney Repair team documents every Lyndhurst inspection with photos you can see and a plain-English verdict - no jargon, no pressure, just what is wrong and what it costs to fix right.
Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, and Olympia Chimney on every truck. Most jobs finish in one visit. The price we quote is the price on the invoice. And every repair is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
We know Lyndhurst’s housing stock intimately. The 3-inch clay tile liners in these full-height brick masonry chimneys are now 60-90 years old. Gas conversions from original oil systems left oversized flues running cool and wet, so flue-gas condensation eats mortar joints from the inside while Passaic River flood moisture attacks from the base. That’s a double failure mode you won’t find in towns where gas was spec’d from the start or where basements sit above the flood plain.
Our Chimney Repair Services in Lyndhurst
Mortar Repointing
Lyndhurst’s freeze-thaw cycles are brutal on century-old mortar. Water soaks through cracked chimney crowns and lifted caps, then winter nights in the low teens expand that moisture and pop the joints. On a typical Lyndhurst colonial off Park Avenue, we’ll grind out failed joints to proper depth and repoint with color-matched, professional-grade mortar rated for our climate zone. Most repointing jobs run $850-$1,400 for the upper courses, with larger rebuilds scaling from there.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in Lyndhurst’s river-adjacent neighborhoods. Floodwater wicks up from below, saturating the chimney base, while wind-driven rain enters from above. The result is brick that looks like it was hit with a hammer. We remove spalled units, source matching brick where possible, and rebuild with proper bonding patterns. A section rebuild on a Lyndhurst Cape Cod typically falls between $1,200 and $2,400.

Chimney Waterproofing
Water is the enemy of every Lyndhurst chimney, but the source isn’t always obvious. Our waterproofing starts with a Level-2 camera inspection to identify whether moisture is entering through the crown, the cap, the flashing, or wicking up from the flood plain below. We apply vapor-permeable sealers from professional-grade lines that let the brick breathe while repelling liquid water - critical in Lyndhurst, where trapped moisture from either direction will destroy mortar in two to three freeze-thaw seasons. Full waterproofing with crown coating and cap reset runs $650-$1,100.

Flashing Repair
This is the repair we perform most often after Lyndhurst nor’easters. Homeowners call with a ceiling stain six feet from the chimney and assume it’s a roof leak. Nine times out of ten, it’s failed counterflashing at the roof-to-chimney seam. Wind lifts the step flashing, ice wedges it open, and water runs down the interior framing until it finds your drywall. We remove the damaged flashing, inspect the underlying masonry for saturation damage, and install new copper or galvanized counterflashing with proper reglets and sealant. Typical flashing repair in Lyndhurst: $450-$850.

Trusted Brands We Service in Lyndhurst
We stock parts and materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney on every service truck, which means most Lyndhurst repairs don’t wait for a parts run. When we found that rotted Famco damper on the Cape Cod off Ridge Road, we had the replacement on the truck. When a clay tile liner is too far gone for spot repair, we turn to HeatShield’s cerfractory flue sealant or DuraFlex stainless relining systems - both engineered for the low-temperature gas exhaust that dominates Lyndhurst’s converted housing stock. No builder-grade substitutes. The right material for the specific failure we’re looking at.
Common Chimney Repair Problems We See in Lyndhurst Homes
- Winter nor’easters drive rain through lifted or missing chimney caps and cracked crowns. Water soaks the brick, freeze-thaw cycles pop the mortar joints, and by spring you have spalling faces and open joints from the roofline down. We check this first on every pre-season inspection.
- Flashing failures at the roof-to-chimney seam show up as ceiling stains, not chimney leaks. The homeowner calls a roofer; the roofer patches shingles; the stain returns. We inspect the counterflashing reglet and step flashing overlap - the actual failure point - and fix it permanently.
- Floodwater wicking into chimney bases near the Passaic River corrodes damper assemblies and crusts fireboxes with white efflorescence. Homeowners almost always misread this as a roof or flashing leak. The mineral crust is calcium and sulfate salts left behind as floodwater evaporates - a signature of historic flood absorption, not precipitation from above.
- Gas-conversion condensation destroys oversized clay tile liners from the inside out. Those 3-inch flues were engineered for 500°F oil exhaust. Modern gas appliances run 200°F cooler. The result is chronic condensation, acidic flue-gas deposits, and mortar joint erosion that a standard visual inspection from the roof won’t catch - which is why our Level-2 camera inspection examines every joint from the firebox up.

FAQs - Chimney Repair in Lyndhurst
That white crust is efflorescence - mineral salts left behind when water evaporates out of brick or mortar. In Lyndhurst’s Passaic River flood plain neighborhoods, it almost always signals historic floodwater absorption wicking up from the chimney base, not a roof leak. The same moisture that leaves that crust is often rotting your damper blade from below. A Level-2 camera inspection confirms the source. Call (732) 507-9649 for an exact diagnosis - estimates are free.
Yes. In Lyndhurst, the bigger threat to most chimneys isn’t creosote from wood burning - it’s condensation damage from gas appliances venting through oversized, aging clay tile liners, plus moisture intrusion from flood history and freeze-thaw weathering. An annual Level-2 inspection catches liner deterioration, crown cracks, and cap displacement before they become rebuilds. The $89 seasonal tune-up includes a camera look and photo report.
Crown cracks have multiple causes, but Lyndhurst’s severe weather history accelerates them dramatically. Irene and subsequent Passaic surges saturated masonry that then froze hard in winter nor’easters. The thermal shock of rapid wet-dry-freeze cycles - common in river-adjacent Bergen County - separates crown concrete from the brick below and opens hairline cracks into water highways. We seal minor cracks with professional-grade crown coating; larger failures require removal and rebuild. The inspection tells us which.
A ceiling stain on the room below the chimney, often six feet or more from the chimney breast itself, is the classic sign. Water enters at the roof-to-chimney seam, runs down the interior roof framing, and exits wherever it finds a path - usually not directly below the chimney. Homeowners in Lyndhurst’s older neighborhoods call roofers first; roofers replace shingles; the stain returns. We inspect the step flashing, counterflashing reglet, and masonry saturation with a camera to find the actual entry point. Call (732) 507-9649 - we’ll show you the photos.
It affects the damper directly and the liner indirectly. Floodwater wicking into the chimney base corrodes steel damper blades and hardware - we’ve replaced dozens in the Kingsland and River Road sections that were locked solid with rust and mineral crust. The liner suffers when that same moisture combines with cool gas exhaust to keep the flue chronically damp, accelerating mortar joint erosion between clay tiles. It’s a one-two punch unique to Lyndhurst’s flood-plain housing stock: moisture from below, condensation from inside. Our inspection protocol starts at the firebox damper for exactly this reason.
