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.

Our Chimney Cap & Crown Services in Roselle Park
Multi-Flue Cap Installation
Roselle Park’s two-family homes along West Westfield Avenue and Chestnut Street regularly need multi-flue caps sized for shared brick stacks where two flues exit side by side. A standard single-flue cap won’t seal properly here, and a poorly fitted cap actually worsens the cross-drafting between units. We measure the chase, fabricate or order a cap with proper screen height and lid overhang, and seal the perimeter with high-temperature silicone so each flue draws independently. Most multi-flue cap installations in Roselle Park run $450-$850 including hardware and labor.
Crown Repair & Repointing
The original crowns on Roselle Park’s century-old chimneys were poured with soft mortar mixes that crumble under Union County’s freeze-thaw assault. We grind out spalled material, apply a bonded crown coat formulated for Northeast winters, and repoint the top brick courses. For crowns with structural cracking or severe deterioration, we may recommend a full rebuild. Crown repair in Roselle Park typically costs $280-$650; full crown replacement runs $800-$1,200 depending on stack width and access.
Custom Cap Fabrication
Some Roselle Park stacks need what no catalog carries: odd flue spacing, non-standard chase dimensions, or heritage requirements. We work with Copperfield and Gelco to specify custom stainless steel or copper caps with proper lid pitch, animal screening, and pull-ring access for future sweeping. Custom caps for Roselle Park homes generally fall between $600-$1,100 installed, with turnaround under two weeks once measured.
Crown Coating & Preventive Sealing
For crowns with early surface cracking but sound structure, we apply HeatShield crown coat - a breathable, flexible sealant that bridges hairline cracks before water penetrates to the flue liner below. This is preventive work, not cosmetic, and we only recommend it where the camera shows the crown base is solid. Crown coating in Roselle Park runs $280-$450 and adds years of service to a sound crown.

Trusted Brands We Service in Roselle Park
We install and repair with professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - no builder-grade substitutes that fail in their third winter. For Roselle Park customers, this means we stock common cap sizes and crown repair compounds locally, so we’re not ordering parts from a warehouse while your chimney takes on rain. Our trucks carry multi-flue hardware, stainless screening, and high-temperature sealants suited to the borough’s older masonry. If your stack needs something custom, we spec it from the same suppliers we’ve used for decades, not whatever’s cheapest this quarter.
Common Chimney Cap & Crown Problems We See in Roselle Park Homes
- Freeze-thaw spalling on original crowns. Union County’s wet winters drive moisture into soft century-old mortar, which expands when frozen and flakes off in spring. By the time a Roselle Park homeowner notices a ceiling stain, water has already tracked down the flue and saturated the plaster below.
- Missing or undersized caps on shared two-flue stacks. A single cap stretched across two flues leaves gaps where rain and squirrels enter, or worse, creates pressure imbalances that let a first-floor gas appliance backdraft into an upstairs fireplace flue.
- Oversized flues with no cap screening. Roselle Park’s coal-era chimneys were built for hot, fast draft. Modern gas exhaust cools quickly in these wide flues, and without a proper cap to reduce moisture intrusion, the resulting glazed creosote becomes a fire hazard a standard brush cannot remove.
- Cracked crowns allowing wythe wall deterioration. In attached two-family homes, the thin brick wall separating two flues relies on a sound crown to keep water out. Once the crown fails, that dividing wall softens and shifts, worsening cross-flue leakage between units.

FAQs - Chimney Cap & Crown in Roselle Park
Yes, a properly sized multi-flue cap is the correct solution for Roselle Park’s shared two-flue stacks, and it’s what we install most often in the borough’s attached housing. The cap must span both flue openings with adequate lid overhang and independent screen walls so each flue draws without pressure interference. We measure the chase, account for the wythe wall thickness, and set the cap on a bed of high-temperature sealant so water sheds away from both flues. Call (908) 923-3159 to schedule a measurement - estimates are free.
The backdrafting stems from the shared chase geometry in Roselle Park’s two-family stacks, not from a defective appliance. When the upstairs fireplace flue stays cold from infrequent use, it becomes the path of least resistance for exhaust from the first-floor gas appliance, especially if the crown is cracked or the cap is missing and allowing pressure equalization across the thin wythe wall. Our Level 2 camera inspection identifies the exact breach point, and sealing the crown plus installing a proper multi-flue cap restores independent draft to each flue. Call (908) 923-3159 - we’ll show you the problem before recommending any repair.
No. We do not recommend cap or crown work, or any chimney repair, without camera evidence you can see for yourself. Our technician runs a Level 2 inspection, records video and still images of the cracked crown, spalled mortar, or missing cap screen, and explains the finding in plain English before any estimate is written. If the problem can safely wait, we say so. The photos are yours to keep either way. Call (908) 923-3159 to schedule an inspection.
It depends on what the camera shows beneath the surface damage. If the crown base is sound and the cracking is superficial, we can grind back the spall and apply a bonded crown coat for $280-$450. If water has penetrated to the point that the crown is separating from the brick courses below, or if the reinforcement mesh is exposed and rusting, full replacement at $800-$1,200 is the only lasting fix. We make that determination with the camera, not from the ground with binoculars. Call (908) 923-3159 for an inspection and exact quote.
Yes, and in Roselle Park’s two-family housing it matters for reasons beyond the fireplace itself. An uncapped or poorly crowned flue lets rain and animals enter year-round, but more critically, that cold, unused flue becomes a sink for exhaust from the other unit’s gas appliance. The cap and crown are what maintain separation between flues in a shared stack. Even if you never light a fire, the condition of your cap and crown affects your neighbor’s safety and your own ceiling plaster. Call (908) 923-3159 for a camera inspection - we’ll tell you honestly whether work is needed now or can wait.
