Our Chimney Cap & Crown Services in Fanwood
Crown Repair
Fanwood’s freeze-thaw cycle destroys soft mortar crowns. Temperatures swing across 32°F repeatedly through winter, water seeps into hairline cracks, freezes, and expands - spalling chunks off 1920s parging. We cut out the damaged material and repour with professional-grade crown mix, sloped correctly to shed water. On a recent job near La Grande Avenue, we saved a 1936 chimney from full rebuild by rebuilding the crown before the flue interface cracked through.
Crown Coating
For crowns with surface cracking but sound structure, we apply flexible crown coating from HeatShield or similar professional-grade systems. This buys years on a Fanwood chimney that isn’t ready for full repair. We won’t sell it if the crown is too far gone - we’ll show you the photo and explain why. A square deal: no surprises on the bill.
Multi-Flue Cap Installation
Nearly all Fanwood homes built between the 1920s and 1950s have original dual-flue chimneys with a fireplace flue and an abandoned or improperly relined gas-conversion flue, making multi-flue crown failure and cap incompatibility the rule rather than the exception. A single cap spanning both flues prevents water, animals, and debris from entering either passageway. We size and install caps from Copperfield and Famco that fit your exact flue spacing - no universal “close enough” hardware.
Cap Replacement
Original cast-iron caps on Fanwood chimneys rust through after 70+ years. Galvanized caps from the 1970s replacements are often failing now too. We remove the old cap, inspect the flue walls for hidden damage, and install a proper fit in stainless steel or copper. Done right - and we stand behind it.
Custom Cap Fabrication
Some Fanwood chimneys have odd flue spacing, oversized combined flues, or decorative brickwork that rules out stock caps. We measure, fabricate, and install custom solutions that fit properly and look correct on a Tudor Revival or Colonial Revival home. The homeowner on Martine Avenue - the one with the 1929 chimney and rusted cast-iron cap - we installed a custom two-flue Copperfield cap with a stainless steel liner transition to seal both the active fireplace flue and the abandoned boiler flue, preventing moisture from entering the now-inert passage. The homeowner avoided a full rebuild.

Common Chimney Cap & Crown Problems We See in Fanwood Homes
- Freeze-thaw cycles spall soft mortar crowns on 1920s-1950s chimneys, often cracking across both flues. Union County’s winter temperature swings repeatedly cross the freezing point, forcing water into microscopic cracks and exploding them outward. By March, we’re repairing crowns that were intact in October.
- Improperly relined gas-conversion flues accumulate condensate that corrodes metal caps and loosens crown sealants. When Fanwood’s oil boilers converted to gas, many flues were abandoned or patched with undersized liners. The resulting condensate drips back onto the crown, eating through cap fasteners and crown coating from underneath.
- Original one-piece terra cotta crowns on multi-flue chimneys deteriorate unevenly, leading to differential settlement and gaping at the flue-crown interface. We’ve measured gaps over an inch wide where the crown has pulled away from the flue tile, open to rain and squirrel entry.
- Abandoned dual-flue chimneys suffer cap incompatibility when homeowners install single-flue caps on one flue only. Water pours into the uncapped flue, saturating the dividing wall and accelerating liner collapse in the active flue. A proper multi-flue cap solves both at once.

FAQs - Chimney Cap & Crown in Fanwood
No. A properly sized multi-flue cap covering both flues is the correct solution for most Fanwood dual-flue chimneys. Separate single-flue caps leave gaps where water enters the abandoned flue, and they rarely fit the close flue spacing common on 1930s construction. We measure your flue centers and install a cap that seals the entire crown surface. Call (855) 950-3861 and we’ll check your spacing - estimates are free.
Union County temperatures cross 32°F dozens of times each winter, forcing water into crown cracks, freezing it into ice that expands 9%, and spalling off surface material with each cycle. Fanwood’s older soft mortar crowns absorb more water than modern hard-fired brick, so they deteriorate faster than crowns in milder or more stable climates. Crown coating or repair before winter is the best prevention. We can assess your crown’s condition and give you a straight recommendation.
Sometimes, if the crack is truly surface-level and the crown structure is sound. We apply professional-grade flexible crown coating that bridges hairline cracks and sheds water. But if the crack runs deep, if the crown is unevenly settled, or if there’s deterioration around the flue interface, patching wastes money - the crack returns within a season or two. Our inspection photos show you which situation you’re in. No pressure either way. Call (855) 950-3861 for an honest assessment.
A cap helps by keeping rain and animals out, but it doesn’t fix the underlying liner problem. On Fanwood’s abandoned gas-conversion flues, we often recommend sealing the flue top with a stainless steel liner transition as part of the cap installation - this stops condensate accumulation and prevents the moisture that corrodes your active flue from below. The Martine Avenue job we mentioned: that’s exactly what we did, and the homeowner avoided a $4,000+ rebuild. We’ll show you what your flue looks like inside.
A custom multi-flue cap in Fanwood typically runs $650-$890 in stainless steel or $850-$1,400 in copper, including measurement, fabrication, and installation. The price depends on flue count, spacing, roof accessibility, and whether we need to address sealing on an abandoned flue. Standard multi-flue caps fit many Fanwood chimneys and cost less - we only recommend custom when stock won’t work properly. Call (855) 950-3861 for exact pricing on your chimney - estimates are free, and we bring samples to show you.
