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 Haddon
Chimney cap and crown work in Haddon Township typically runs $340-$890 depending on whether you need a standard cap installation, crown rebuild, or both, and most jobs are completed in a single visit with materials stocked for our local market. If you’re seeing white staining on your upper brick courses, spalling mortar, or water in your firebox, the crown or cap is usually the first place we look. Call (856) 543-2929 - a live person answers, and we’ll schedule a Level 2 camera inspection so you see exactly what we see before any work is approved.
We’ve been driving to Haddon Township for over 42 years, and our crews know the difference between a 1920s Craftsman bungalow off Haddon Avenue and a postwar cape on Cuthbert Boulevard. Dispatch is coordinated from our New York City office, but the trucks that roll to your curb carry parts sized for the older flues and crown profiles common here. That matters because Haddon’s housing stock is dominated by 1910-1955 masonry homes whose chimneys were originally built for coal or fuel-oil appliances, then adapted for gas heat - almost always without proper relining. Our Chimney Cap & Crown team documents every inspection with photos and a plain-English verdict, and nothing gets recommended without evidence you can see for yourself.
Why Hearthstone Chimney Co. Is Haddon’s Preferred Chimney Cap & Crown Company
We’ve earned our reputation in Haddon the slow way: by showing up when we say, explaining what we found, and fixing only what needs fixing. Homeowners here tend to stay in their houses for decades, and they’ve heard every upsell pitch in the book. We don’t pitch. We run a camera, hand you the photos, and tell you what the lens shows.
Our 90-Day Done Right Promise is backed in writing with no arguing - if it’s not right, we come back. No paperwork maze, no voicemail tag. Calls are answered by a live person 24 hours a day, 7 days a week, because a chimney leak doesn’t wait for business hours. Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like Gelco and Olympia Chimney on every truck.
We know Haddon’s specific failure patterns: the inside-out deterioration of terracotta liners in oversized coal-era flues, the lime-based mortar crowns that crumble under Delaware Valley freeze-thaw cycling, the missing caps that let squirrels nest above bedrooms on Cuthbert Boulevard. That local knowledge means faster diagnosis and no guesses on your bill.
Our Chimney Cap & Crown Services in Haddon
Cap Installation
A proper chimney cap in Haddon isn’t decorative - it’s the first defense against rain, animals, and debris entering a flue that may already be compromised by decades of condensate damage. For the pre-WWII colonials and bungalows common here, we size caps to the actual flue opening, not the chimney’s exterior dimensions, because many of these chimneys were built with multiple flues or oversized coal-era openings that standard big-box caps won’t seal. A typical cap installation in Haddon runs $180-$340 for a single-flue stainless unit, including proper mounting and a drip edge that directs water away from brick already stressed by efflorescence.
Cap Replacement
Cap replacement in Haddon often reveals the real problem: the original cap was never properly secured, or it was the wrong size for a converted flue, or it blew off in a nor’easter years ago and nobody noticed until the crown started spalling. We remove the old unit, inspect the flue and crown beneath it with a camera, and install a replacement that fits. If your terracotta liner is cracked - common in Haddon’s 70-110-year-old chimneys - we’ll show you the photo and explain whether the cap replacement can proceed or if liner work needs to happen first. Cap replacement in Haddon typically costs $220-$390.
Crown Repair
Crown repair is where we see the most unnecessary upselling in Haddon. A cracked crown does not automatically mean a full rebuild. We differentiate between hairline surface cracking - which we address with a flexible coating after proper surface prep - and structural failure where the crown has deteriorated to exposed aggregate or separated from the brick course below. Haddon’s freeze-thaw pattern is especially destructive here: frequent partial thaws through December-February let water infiltrate lime-based mortar repeatedly, expanding and contracting across a single season rather than freezing once and staying frozen. Crown repair with coating runs $340-$620 in Haddon; full rebuilds start around $780 when the underlying brick course is compromised.
Crown Coating
Crown coating is our most specified service in Haddon for good reason. The flexible, waterproof coatings we apply - compatible with HeatShield systems for integrated protection - bridge hairline cracks and seal the porous surface of aging crowns without the cost or disruption of demolition. For the 1940s capes and ranches near Haddon’s border with Cherry Hill, where crowns are often original poured mortar beds, coating after proper joint repair can add 10-15 years of service life. We never coat over active deterioration or structural cracks; the camera inspection determines candidacy. Crown coating in Haddon ranges $290-$480.
Multi-Flue Cap
Multi-flue caps solve a specific Haddon problem: chimneys built with two or three flues serving separate appliances, common in homes that once had coal heat plus a kitchen range or later added a fireplace insert. A single cap spanning all flues protects the entire crown surface and eliminates the gaps between individual caps where water pools. We were on a 1925 brick colonial off Haddon Avenue where the cap had been missing for years and the crown had spalled down to exposed aggregate. Our tech ran a Level 2 inspection camera down the flue, showed the homeowner third-degree creosote glazing above the smoke chamber and a cracked crown edge, then installed a custom Gelco multi-flue cap and rebuilt the crown with a flexible coating after the decayed mortar was removed. Multi-flue caps in Haddon run $420-$780 depending on span and material.
Custom Cap
Custom caps are necessary when Haddon’s non-standard flue configurations - oversized coal-era openings, multiple flues of different diameters, or exterior chimneys with decorative brick corbelling - rule out catalog units. We measure on-site, fabricate to order from copper or stainless, and install with proper clearances and fastening for our wind exposure. Custom caps in Haddon start around $520 and range to $1,200 for large multi-flue copper with decorative bands.

Common Chimney Cap & Crown Problems We See in Haddon Homes
- Inside-out terracotta liner deterioration. Haddon’s chimneys were sized for coal and oil, then converted to gas without relining. The oversized flue runs cool, condenses acidic exhaust against 70-110-year-old terracotta, and cracks it from the inside. Moisture and creosote then reach the surrounding brick, causing spalling that looks like a crown problem but originates below. We find this with the camera, not by guessing from the roof.
- Crown crumbling from freeze-thaw cycling. The Delaware Valley’s December-February pattern of partial thaws is harder on lime-based mortar crowns than sustained deep freezes would be. Water infiltrates, freezes, expands, thaws, infiltrates again - sometimes a dozen cycles per season. By March the crown surface is spalled and the drip edge is gone.
- Missing caps accelerating upper-course spalling. When caps are missing or undersized, rain enters directly and combines with efflorescence salts already present in brick from decades of condensate migration. The result is flaking, spalling brick on the upper chimney courses that accelerates once started and won’t stop until the water source is eliminated.
- Improper prior repairs trapping moisture. We’ve removed thick cement crowns poured over original lime mortar in Haddon homes - the cement is impermeable, traps moisture, and accelerates decay of the brick beneath. Proper crown repair breathes appropriately for the materials and era of construction.

FAQs - Chimney Cap & Crown in Haddon
You need a camera inspection to know, not a sales pitch. Original terracotta in Haddon’s coal-era chimneys is often cracked from decades of gas condensate, but the cap and crown may be sound while the liner needs attention, or vice versa. We run a Level 2 inspection, show you the photos, and explain what the lens sees. If the crown is cracked and the liner is intact, crown work protects the flue. If both are compromised, we sequence the repairs so you’re not paying for work that will be disturbed later. Call (856) 543-2929 for a free estimate.
Haddon’s Delaware Valley location means dozens of partial freeze-thaw cycles per winter rather than one deep freeze that stays frozen. Each cycle lets water infiltrate lime-based mortar, expand on freezing, then thaw and infiltrate deeper. Sustained cold would be kinder. This is why we see more crown spalling in Haddon than in northern New Jersey, and why our crown coatings emphasize flexibility and breathability over mere waterproofing. The repair must move with the material, not seal it in a shell.
That white staining is efflorescence - mineral salts carried out of the brick by moisture migrating through the masonry. In Haddon, it’s often the signature of a chimney that served coal, then oil, then gas, with condensate working through an oversized or cracked flue for decades. A missing or failed cap accelerates it by letting rain enter directly, but the underlying cause may be liner deterioration. We inspect to distinguish between a cap problem, a crown problem, and a flue problem. Sometimes all three need attention; sometimes a proper cap and crown repair stops the moisture while liner monitoring continues. Camera evidence decides.
Yes, if the crown is structurally sound. Custom caps are fabricated to your flue dimensions and chimney profile, then mounted with proper clearances and fastening independent of crown condition. We inspect the crown surface beneath the mounting area; if it’s spalled but the structural bed is intact, we repair locally and install. If the crown has deteriorated to exposed aggregate or separated from the brick course, cap installation without crown repair would be temporary at best. The camera and a rooftop assessment give you the straight answer.
Usually yes, for two-flue chimneys common in Haddon’s 1920s-1950s housing. A multi-flue cap covers the entire crown surface between flues, eliminating the gaps where water pools and debris collects. Individual caps leave exposed crown between them, and if one fails or blows off, the other doesn’t protect the gap. We measure your flue spacing and crown dimensions, then specify a unit with proper mesh screening and a drip edge that extends beyond the chimney perimeter. For Haddon’s wind exposure and the non-standard flue spacing in many older homes, custom multi-flue caps are often the right choice.
