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.

AfterFast, Reliable Chimney Cap & Crown Across Florence
A chimney cap and crown repair in Florence typically costs $280-$780 depending on whether you need a standard cap replacement or full crown rebuild, and most jobs are completed in a single visit. If you live in the Roebling historic district or anywhere along the Delaware River in Florence, the shared-stack, century-old masonry common to this area demands specific expertise that generic cap installers rarely encounter. Call us at (856) 519-0832 - a live person answers 24 hours a day, and we’ll book your free estimate at a time that works.
We’ve been working on Florence chimneys for decades. Our crews know the difference between a mid-century ranch near Route 130 and an original Roebling row home on Second Avenue. That local knowledge matters when we’re sizing a multi-flue cap for a shared stack or diagnosing why your crown cracked again after last winter. Scheduling and dispatch are coordinated from our metro office, but the technicians who arrive at your door live and work in this area.

We know Florence’s two housing stocks intimately: the Roebling-area brick homes built 1905-1920s with aging mortar joints and original clay-tile flues, and the suburban tract construction elsewhere in the township. Both need different approaches. A crown coating on porous century-old brick in Roebling requires different prep than the same job on a 1970s chimney in Florence Crossing.
Our Chimney Cap & Crown Services in Florence
Cap Installation
New cap installation in Florence runs $220-$450 for a standard single-flue stainless steel unit, or $480-$920 for a custom multi-flue cap on a shared Roebling stack. We size every cap to your flue count and appliance type, not to what’s in stock at the supply house. In the Roebling district, where attached homes share chimney stacks, we routinely install multi-flue caps that seal all outlets while maintaining proper draft for each appliance. We use professional-grade materials from Famco and Copperfield - no builder-grade substitutes that rust through in three seasons.
Cap Replacement
When your existing cap is rusted, wind-damaged, or improperly sized, replacement typically costs $180-$380 for standard jobs, or $420-$780 for custom multi-flue configurations. Florence’s river-valley winds and freeze-thaw cycling beat up caps faster than inland locations. We see a lot of store-bought caps that were never secured to a sound crown - they blow off or drop into the flue after the first hard winter. Our techs mount replacement caps into repaired or rebuilt crowns, not into spalling century-old brick that won’t hold a fastener.
Crown Repair
Crown repair in Florence averages $340-$620 for crack sealing and partial rebuild, or $680-$1,200 for full crown replacement on larger multi-flue stacks. Original coal-era crowns in Roebling row homes often span multiple attached flues and crack along the party-wall seam. Because the mortar joints are already spalling from Delaware River humidity and freeze-thaw, water runs straight down the shared stack instead of shedding off. We rebuild with proper slope and overhang, then finish with a professional-grade coating.
Crown Coating
Crown coating - a waterproof membrane applied over sound but porous masonry - typically runs $280-$520 in Florence. This is our most cost-effective option for crowns that are cracked but structurally intact. We use HeatShield and Gelco coatings formulated for masonry exposed to harsh freeze-thaw cycling. In Florence, where spring fog and river humidity accelerate moisture infiltration, a proper crown coating can add years of service before rebuild becomes necessary. We won’t sell you a coating if the crown is too far gone - that’s a conversation, not a pitch.
Multi-Flue Cap
Multi-flue caps are essential for many Florence properties, especially in Roebling’s attached brick row homes where two or more appliances vent through a single chimney stack. Custom multi-flue installations range $480-$920 depending on stack dimensions and material choice. These caps cover all flue outlets in one integrated unit, preventing cross-contamination between your fireplace and a neighbor’s furnace while keeping rain, debris, and animals out of the entire assembly. We measure on site and fabricate to fit - no guesswork from a catalog.
Custom Cap
Custom caps for unusual flue configurations, decorative requirements, or heritage-sensitive installations in Roebling’s historic district run $620-$1,400. We’ve fabricated copper and stainless custom caps for everything from triple-flue stacks on converted Roebling duplexes to oversized single flues on river-view homes near the Delaware. Every custom cap includes proper screening, correct draft clearance, and mounting engineered to your crown condition, not just your flue opening.

Trusted Brands We Service in Florence
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - brands that hold up to Florence’s river-valley humidity and temperature swings. We stock common cap sizes and crown coating materials locally, so most Florence jobs don’t wait on parts. When a Roebling row home needs a custom multi-flue cap, we fabricate from measured specs rather than forcing a near-fit from a standard catalog item. The right material for the job, installed correctly, backed by our 90-Day Done Right Promise.
Common Chimney Cap & Crown Problems We See in Florence Homes
- Shared-stack cross-contamination in Roebling row homes. A neighbor’s gas furnace or water heater vents into the same flue as your fireplace. Without a properly fitted multi-flue cap and sealed crown, draft pressure pulls exhaust, sulfur odors, and creosote across the party wall into your living space. This barely registers in Burlington City or Bordentown’s wider-lot housing, but it’s a defining pattern in Florence’s Roebling district.
- Cracked crowns along party-wall seams. Original coal-era crowns spanning multiple attached flues crack where the masonry meets the party wall. Combined with spalling mortar joints from Delaware River freeze-thaw, water channels straight into the stack instead of shedding off. We rebuild with proper expansion joints and slope.
- Store-bought caps on shared stacks. A homeowner installs a single-flue cap from a hardware store on a stack serving two attached homes. The neighbor’s appliance still vents freely into your flue, and draft imbalance pulls contaminants across. We see this repeatedly on Florence inspections - the wrong cap is worse than no cap.
- Caps mounted into deteriorated brick instead of sound crown. Straps or masonry screws driven into century-old porous Roebling brick fail after the first hard winter or spring thaw. The cap drops, leaving the flue open to fog moisture, animal entry, and internal water damage. We anchor into repaired or rebuilt crowns, not crumbling brick.

FAQs - Chimney Cap & Crown in Florence
No, a single-flue cap on only your outlet won’t solve cross-contamination on a shared stack. You need a properly sized multi-flue cap that covers all flue openings with correct draft clearance for each appliance, plus a sealed crown to prevent pressure differentials from pulling exhaust across the party wall. We inspect the full stack, document what we find with camera photos, and quote the right configuration. Call (856) 519-0832 for a free estimate.
Most original Roebling flues were built unlined for coal combustion and were never retrofitted when converted to wood or gas. Our Level-2 camera inspection shows you the flue interior in real time - clay tile, bare masonry, or a stainless liner - and we explain what you’re seeing in plain English. Capping an unlined wood-burning flue without addressing the liner condition is a fire hazard we won’t ignore. Call (856) 519-0832 to schedule.
Florence’s location on the Delaware River exposes masonry to persistent humidity, morning fog, and repeated freeze-thaw cycling that accelerates spalling and crack propagation. Original Roebling crowns are especially vulnerable because the porous century-old brick absorbs more moisture than modern materials, and the coal-era design often lacks proper slope or overhang. A coating or rebuild with modern waterproofing and correct drainage geometry breaks the cycle. Call (856) 519-0832 for an inspection and lasting solution.
It’s both, and it’s common in Roebling’s attached housing. The shared flue needs proper sizing and separation for each appliance type - gas water heaters and wood fireplaces have different venting requirements - plus a multi-flue cap that maintains correct draft for each outlet without allowing cross-flow. Our inspection determines whether the flue can be safely shared with a cap and liner modifications, or whether separate venting is required. Call (856) 519-0832 for a camera inspection and written verdict.
Yes, especially in Florence’s river-valley climate and doubly so for Roebling’s century-old shared stacks. Moisture intrusion, freeze-thaw damage, and animal nesting happen whether you burn or not. An unlined or deteriorating flue with a missing or failed cap becomes a carbon monoxide pathway and structural liability regardless of fireplace use. Our $89 Seasonal Tune-Up includes full inspection, and the 5% Senior and Veteran discount applies. Call (856) 519-0832 to book.
