Our Chimney Cap & Crown Services in Mount Holly
Custom Cap Installation
Mount Holly’s historic chimneys weren’t built to standard dimensions. The corbeled brickwork and offset flues in Federal-era homes often require caps that can’t be pulled off a warehouse shelf. We measure on-site, fabricate custom caps from stainless steel or copper, and secure them with proper mounting systems that won’t damage antique brick. For the row homes along High Street and the surrounding historic core, we frequently design multi-flue custom caps that cover complex chimney configurations while preserving the roofline’s period character.
Crown Repair
A proper crown repair on a Mount Holly antique chimney starts with understanding what the original masons used. The soft lime mortar common to 18th- and early 19th-century construction breathes differently than modern Portland cement - seal it with the wrong material and you’ll trap moisture, accelerate spalling, and destroy what’s left of the original brick. We remove deteriorated material, assess the structural integrity of the underlying brick, and apply crown coatings or rebuilds using materials compatible with historic construction. In the field, we’ve found that crowns on homes near the Rancocas Creek floodplain often show accelerated deterioration from ground moisture wicking upward through the chimney structure.
Multi-Flue Cap Installation
This is where Mount Holly’s housing stock gets genuinely unusual. The shared chimney stacks between attached row homes - common throughout the historic district - require multi-flue caps that protect both flues independently while maintaining proper draft separation. A single cap failure on one side can vent combustion gases into the neighbor’s living space, a hazard the local fire marshal has cited repeatedly. We install multi-flue caps with individual venting chambers, spark arrestors, and animal guards sized to each flue’s appliance load. Our Chimney Cap & Crown team has handled dozens of these shared-stack configurations.
Crown Coating
When the crown’s structure is sound but the surface is weathered, a professional-grade crown coating can add 10-15 years of protection without the cost of full rebuild. This is often the right choice for Mount Holly’s mid-century Cape Cods and ranches on the borough’s outer streets, where concrete crowns were poured in the 1950s-1970s and are showing surface cracking but haven’t yet failed structurally. We use flexible, breathable coatings that accommodate the thermal expansion and contraction from Burlington County’s hard freeze-thaw cycles. The coating is applied after thorough cleaning and minor crack repair, with a finished surface pitched to shed water away from the flue.
Cap Replacement
Sometimes the cap is simply done. Galvanized steel caps rust through after 15-20 years in Mount Holly’s humid summers. Cheap aluminum caps blow off in winter wind events. We’ve replaced caps that were “secured” with bent coat hangers by a previous owner. We remove the old cap, inspect the flue and crown beneath it (damage often hides under a bad cap), and install a replacement from Copperfield or Famco sized precisely to your flue. Stainless steel carries a lifetime warranty against rust-through. Copper weathers to a patina that complements historic brick.

Common Chimney Cap & Crown Problems We See in Mount Holly Homes
- Freeze-thaw spalling on lime mortar crowns. Mount Holly sits in the Burlington County interior, where hard freeze-thaw cycles each winter attack already-compromised antique mortar joints. Hairline cracks from summer widen with each freeze, letting water penetrate deeper. By March, chunks of crown are on the roof or in the yard.
- Shared-stack moisture and exhaust migration. In Mount Holly’s historic district, many Colonial-era row homes share a single chimney stack between two units. A cap or crown failure on one side can vent combustion gases into the neighbor’s living space - a hazard the local fire marshal has cited repeatedly. Both owners need coordinated inspection and repair.
- Corbeled offsets trapping creosote and hiding crown damage. The stepped brick corbelling common in early Mount Holly construction narrows the flue in ways that standard camera inspections can’t navigate. Crown damage behind these offsets goes undetected until water intrusion becomes visible inside the home.
- Humid summer moisture infiltration into unlined flues. Mount Holly’s humid Mid-Atlantic summers allow significant moisture into open or unlined flues during the off-season. By October, that moisture has accelerated interior deterioration, and the first fire of the season reveals cracked firebrick, deteriorated mortar, or a rusted damper - all made worse by a missing or failed cap that should have kept rain out.

FAQs - Chimney Cap & Crown in Mount Holly
Not necessarily both, but you do need coordinated inspection and a multi-flue cap designed to protect both flues independently. We’ve replaced a crumbling crown on a shared chimney at a High Street row home whose lime mortar had spalled from decades of freeze-thaw. The old crown was letting water seep into both flues, accelerating decay; we installed a custom copper cap with a multi-flue design to protect both neighbors. If only one side is damaged now, the other should still be inspected - shared stacks mean shared vulnerabilities. Call (866) 580-4069 and we’ll coordinate with both households.
It depends on what’s crumbling and why. Surface cracking on a structurally sound crown can often be coated for $340-$520. If the underlying brick is spalling or the crown has lost its pitch, partial or full rebuild is the only lasting fix. For Mount Holly’s antique chimneys, we use lime-based repair materials that breathe with the original masonry - modern Portland cement traps moisture and accelerates the very damage you’re trying to stop. We’ll photograph the crown, show you exactly what we see, and recommend the least invasive repair that will actually last. Estimates are free.
Because the repair was likely done with the wrong material or without addressing the underlying cause. Mount Holly’s hard freeze-thaw cycles will destroy any crown coating that’s too rigid or applied over active moisture intrusion. We’ve found that crowns on homes with unlined flues often fail repeatedly because combustion condensation from gas appliances soaks the brick from the inside while rain attacks from outside - the crown is caught in a moisture sandwich. The permanent fix requires stopping both water sources: proper venting, possibly a liner, and a crown repair with materials rated for thermal cycling. Call (866) 580-4069 and we’ll diagnose why yours keeps failing.
Yes, and possibly more than for a wood-burning fireplace. Gas combustion produces water vapor that condenses in cool flue walls; without a proper cap, rain adds to that moisture load, and without a liner, the acidic condensate attacks the mortar joints directly. In Mount Holly’s shared-stack row homes, this is particularly dangerous - a failed cap on your gas-venting flue can introduce carbon monoxide into adjacent living spaces through deteriorated party-wall mortar. We recommend a Level-2 camera inspection to assess flue condition, then proper capping and likely liner installation. The cap is not optional protection.
Yes. We fabricate custom copper caps with clean lines and proper proportions that complement rather than clash with historic rooflines. For Mount Holly’s Federal-era homes, we avoid the boxy, industrial look of standard galvanized caps and can match details like flared skirts, beaded edges, or verdigris patina finishes. The cap still needs to function - proper spark arrestor, animal guard, and draft clearance - but function and appearance aren’t mutually exclusive. We’ll show you samples and fabricate to your chimney’s exact dimensions. Call (866) 580-4069 to discuss options.
