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.

We’ve been driving to Bellmawr for over four decades. The borough’s tight grid of post-war streets - Bell Avenue, Browning Road, the numbered avenues off Route 168 - holds thousands of cape cods, ranches, and twins built between 1940 and 1965, nearly all with original single-stack masonry chimneys now pushing 80 years old. Our Chimney Cap & Crown in Bellmawr crews know these chimneys: the thin wash-sloped crowns, the oversized clay flue liners left over from oil and coal conversions, the efflorescence that runs down brick after brick every freeze-thaw season. Dispatch and scheduling run from our New York City office, but the trucks that pull up to your curb carry technicians who’ve worked this specific housing stock for years.
Why Hearthstone Chimney Co. Is Bellmawr’s Preferred Chimney Cap & Crown Company
Bellmawr homeowners tend to stay put. They’ve lived in the same house for twenty, thirty, sometimes forty years. They’ve also been burned by contractors who recommended work that didn’t need doing, or did work that failed inside a season. We understand that suspicion. It’s why we built our company around documentation you can see and a promise we put in writing.
Our Chimney Cap & Crown team serves Bellmawr with the 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. Every inspection ends with photos from the camera and a plain-English verdict: here’s what we found, here’s what it means, here’s what we’d do if it were our house. No upselling. No thousand-dollar surprises sprung after the ladder’s already up.
Calls are answered by a live person, every hour of every day. Not a voicemail. Not a callback queue. Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like Gelco, Olympia Chimney, and Famco - no builder-grade substitutes pulled from a hardware store shelf. Most jobs finish in one visit, with upfront pricing agreed before we start. The number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Bellmawr
Cap Installation
A new chimney cap on a Bellmawr home isn’t a universal part. The borough’s converted-gas chimneys often vent through flue liners sized for oil burners - liners that run wet and cold, producing condensation a standard cap can’t manage. We measure your flue, check your draft with the camera running, and specify a cap that fits the actual conditions. A Gelco stainless cap with proper mesh screening keeps out rain, animals, and wind-driven debris while letting your oversized flue breathe enough to dry between cycles. Typical cap installation in Bellmawr: $280-$480 for a standard single-flue unit, $420-$680 for multi-flue configurations common on twins and row homes.

Cap Replacement
Caps rust, blow off in nor’easters, or get bent by falling branches. On Bellmawr’s narrow lots, where chimneys sit close to mature oaks and neighboring rooflines, we see this often. But we also see caps that were never right to begin with - too small for the flue, wrong mesh size, no overhang to shed water off the crown. We pull the old cap, inspect the crown and flue tile beneath it (this is where damage hides), and install a replacement that actually protects the stack - part of our Chimney Repair - Bellmawr service. Replacement runs $240-$520 depending on flue count and whether the crown underneath needs attention.

Crown Repair
This is where Bellmawr’s housing stock shows its age. Original crowns from the 1940s-60s were poured thin, sloped with a quick wash, and never meant to survive eight decades of South Jersey freeze-thaw. The mortar joint between crown and brick cracks first. Atlantic moisture seeps in. The crown lifts, spalls, and eventually lets water straight into the chimney structure. We grind out the damaged concrete, rebuild with proper slope and drip edge, and seal the joint to the brick. Crown repair in Bellmawr: $340-$620 for partial rebuilds, $890-$1,400 when the full crown needs replacement.

Crown Coating
Not every cracked crown needs rebuilding. If the structural concrete is sound but the surface is weathered and porous, we apply a flexible crown coating formulated for masonry expansion and contraction. This is particularly effective on Bellmawr chimneys where the freeze-thaw cycle has opened hairline cracks but the crown hasn’t separated from the brick yet. Coating buys years of protection at a fraction of rebuild cost. Typical crown coating in Bellmawr: $280-$450. We only recommend it when the camera and a physical probe confirm the concrete beneath is solid - never as a bandage over structural failure.

Multi-Flue Cap
Bellmawr’s twin homes and narrow-lot row houses often have two flues sharing a single chimney stack - one for a converted gas furnace, one for a fireplace or former oil heater. A multi-flue cap covers both with a single hood, sized to shed water beyond the chimney edges and protect the crown between flues, which we handle through our Fireplace Services in Bellmawr. We fabricate and install multi-flue caps from Gelco and Olympia Chimney stock, measured to your stack’s exact dimensions. Typical range: $520-$780.

Custom Cap
Some Bellmawr chimneys need what doesn’t come off the shelf: odd flue spacing, exterior dimensions that don’t match standard models, or architectural requirements in historic districts. We measure, specify, and install custom caps from Copperfield and Famco, with turnaround typically under two weeks. Custom work starts around $680 and scales with material and complexity.

Trusted Brands We Service in Bellmawr
We don’t guess at what fits your chimney. Our trucks carry professional-grade caps, crowns, and coating materials from Gelco, Olympia Chimney, and Famco - brands that publish specifications for wind load, mesh sizing, and flue clearance, and stand behind their products with real warranties. For custom work, we source through Copperfield. Because we stock common multi-flue and single-flue configurations, most Bellmawr installations happen same-visit after inspection. No waiting two weeks for a part to ship, no substituting a close-enough size that leaks in the first hard rain.
Common Chimney Cap & Crown Problems We See in Bellmawr Homes
- Crown cracks at the mortar joint. Original 1940s-60s crowns were poured thin and wash-sloped for oil-era chimneys. After a few South Jersey winters with temperatures crossing 32°F repeatedly, the mortar joint between crown and brick opens up. Atlantic nor’easters push sustained moisture straight into the stack. We see this on block after block in the numbered avenues off Route 168.
- White efflorescence staining exterior brick. Oversized clay liners on converted-gas homes condense flue gases that wick through the masonry as white mineral deposits. The crown deteriorates from underneath. A cap alone won’t fix this - the flue needs inspection, and the crown needs repair or coating alongside any cap work.
- Missing or undersized caps on narrow-lot chimneys. Bellmawr’s 25-30 foot lots put chimneys close to neighboring rooflines. Rain blows in at angles. Squirrels and starlings nest. The resulting moisture and spalling gets misdiagnosed as a liner problem when it’s often a cap and crown issue that camera inspection clarifies in minutes.
- Improperly vented gas appliances accelerating crown decay. A furnace or water heater vented into an oversized oil-era flue runs below the dew point for much of the heating season. The crown stays damp, freezes, thaws, and crumbles. Correcting the venting configuration - which we document with photos and explain plainly - is often the real fix beneath the crown work.

FAQs - Chimney Cap & Crown in Bellmawr
That white staining is efflorescence - mineral salts left behind when moisture moves through masonry and evaporates. In Bellmawr, it almost always signals an oversized clay flue liner from the home’s original oil or coal heating system, now venting a gas appliance that runs cooler and produces more condensation. The flue gases condense inside the oversized liner, saturate the surrounding brick, and wick out as those white streaks. A cap alone won’t stop it. We run a Level-2 camera inspection to confirm liner sizing and crown condition, then recommend the right combination of cap, crown repair, and possibly liner work. Call (856) 543-2929 - estimates are free.
It depends on what the camera and physical probe reveal. Many 1950s crowns in Bellmawr are structurally sound beneath surface cracking but have lost their waterproofing. In those cases, crown coating after proper prep restores protection for years at $280-$450. If the concrete has separated from the brick, spalled deeply, or lost structural integrity, partial or full rebuild is the honest recommendation - typically $340-$620 for repair, $890-$1,400 for full replacement. We show you the photos and explain which category yours falls into before any work is scheduled.
The crown is the concrete or mortar slab that tops your masonry chimney, sloped to shed water and protect the brick below. The cap is the metal hood that sits above the flue opening, keeping rain, animals, and debris out while letting smoke escape. Your Bellmawr chimney needs both working together: a cracked crown lets water destroy the chimney structure even with a good cap, and a missing cap lets rain and animals damage the flue even with a sound crown. During inspection, we evaluate both and recommend only what’s actually failing.
Most Bellmawr twins have two flues sharing a chimney stack - often one for a converted gas furnace, one for a fireplace or former second heater. A multi-flue cap covers both with a single hood, sized to your stack’s exterior dimensions, and is usually the right choice. Custom caps are reserved for non-standard flue spacing, unusual exterior dimensions, or specific aesthetic requirements. We measure on site and show you both options with prices before you decide.
Most cap and crown issues in Bellmawr are not immediate emergencies, but they worsen every freeze-thaw cycle. A cracked crown in November will be a separated crown by March, with water damage to interior masonry accelerating through the winter. That said, if you’re not using the fireplace and the furnace flue is properly venting, scheduling before the next hard freeze is reasonable. We don’t pressure for urgency we can’t justify. Call (856) 543-2929 and we’ll slot you honestly - sooner if the camera shows active water intrusion, later if the damage is stable and you’re not heating with the affected flue.
