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 White Horse
Chimney cap and crown repair in White Horse typically runs $280-$780 depending on whether you need a cap replacement, crown rebuild, or full multi-flue system, and most jobs are completed in a single visit. If you’re smelling smoke from a neighbor’s fireplace or finding brick flakes in your firebox, the problem often starts at the top of a shared stack that was never designed for how your home is heated today.
We’ve been working on White Horse chimneys for decades. Our crews know the post-war ranches off White Horse Avenue, the Cape Cods clustered near Mercerville Road, and the attached homes where a single masonry stack serves two households. That shared-stack geometry is the defining feature of chimney work here, and it’s why we approach cap and crown jobs differently than we would in a newer suburb with separate flues for every house.

Why Hearthstone Chimney Co. Is White Horse’s Preferred Chimney Cap & Crown Company
White Horse homeowners don’t call us for flashy trucks or discount coupons. They call because their neighbor’s water heater exhaust started showing up in their living room, or because the crown on their 1962 ranch cracked open during last February’s ice storm, and they need someone who understands what they’re looking at.
Our Chimney Cap & Crown in White Horse reputation was built on documenting what we find. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no pressure, no estimate for work you can’t verify. The 90-Day Done Right Promise covers every cap and crown job in writing - if it’s not right, we come back, no arguing, no paperwork chase.
Dispatch and scheduling are coordinated from our New York City office, but the technicians who arrive at your White Horse home are background-checked, uniformed, and carry the professional-grade materials to finish most jobs in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in White Horse
Cap Installation
New cap installation on a White Horse ranch or Cape starts with understanding whether your flue stands alone or shares a stack. A standard single-flue cap from Famco or Copperfield runs $180-$340 installed, but in White Horse’s attached housing, we more often recommend a multi-flue cap that covers the entire chimney top and protects the crown beneath it. The wrong cap leaves gaps where Mercer County’s wind-driven rain gets in, and on a shared stack, it can actually worsen pressure imbalances between adjacent flues.
Cap Replacement
White Horse’s original caps are usually 20-40 years old, galvanized steel rusted through or aluminum that blew off in a nor’easter. Replacement costs $220-$420 depending on flue size and access. We see this constantly near the White Horse Circle, where homes sit close together and roof pitches are shallow enough that technicians can work safely but tight enough that standard caps don’t always fit. When we replace a cap, we inspect the crown beneath it - because in this housing stock, the cap failed because the crown was already failing.
Crown Repair
Crown repair is the most critical service we perform in White Horse. A proper crown is poured concrete with a drip edge, sloped to shed water. The original crowns on 1950s-70s chimneys here were often mortar wash, not concrete, and decades of Mercer County freeze-thaw cycles have spalled them down to the brick. Crown repair runs $480-$720 for a standard rebuild; if the damage extends to the brick courses below, we quote the full scope before starting. We use professional-grade crown sealants compatible with HeatShield and Olympia Chimney systems, and we warranty the work under our 90-Day Done Right Promise.
Crown Coating
For crowns with minor cracking but sound structure, crown coating extends service life 5-10 years at $280-$450. This isn’t a substitute for rebuilding a spalled crown, and we’ll tell you straight if coating would be money wasted. In White Horse, we apply crown coating most often on homes where the oil-to-gas conversion left a low-temperature flue that condenses against the crown from inside - the exterior looks salvageable, but the interior face is deteriorating faster than coating alone can address.
Multi-Flue Cap
The multi-flue cap is our most-specified solution in White Horse’s shared-stack neighborhoods. A single cap covering all flue openings on a chimney top eliminates the gap between separate caps where water and downdraft cross between households. Installed cost runs $420-$680 depending on chimney dimensions and material (stainless or copper from Copperfield or Famco). We size these with enough clearance for each flue’s draft requirements while sealing the crown against weather. On a block of 1950s Capes off White Horse Avenue, we pulled a rusted Famco cap off a shared stack and found the crown spalled down to the brick with a hairline crack running toward the neighbor’s flue opening. We rebuilt the crown, sealed it with a Copperfield multi-flue cap sized for both openings, and confirmed the wood-burning side had second-degree creosote while the adjacent gas water heater flue was condensing hard against cracked clay tile. The fix stopped the cross-draft complaint the homeowner had blamed on her own fireplace.
Custom Cap
Some White Horse chimneys need what no catalog stocks: odd flue spacing, an exterior chase that doesn’t match standard dimensions, or a historical detail the homeowner wants preserved. Custom caps from Copperfield or Olympia Chimney run $580-$980 depending on metal gauge and complexity. We measure on site, fabricate to order, and install with the same single-visit efficiency as standard caps. If your chimney has one opening for a fireplace and another for a water heater - common in converted oil systems - a custom cap with properly sized screening and rain protection for each flue prevents the cross-contamination that standard caps ignore.

Trusted Brands We Service in White Horse
We don’t use builder-grade substitutes. Our trucks carry caps, crowns, and repair materials from DuraFlex, HeatShield, Famco, and Copperfield - brands that professional sweeps specify when the job has to last. For White Horse homeowners, this means we rarely need a second trip for parts. Most cap and crown jobs are completed in a single visit because the right material is already on the truck, sized and ready. When a custom order is necessary, fabrication turnaround is typically under two weeks, and we schedule installation the day it arrives.
Common Chimney Cap & Crown Problems We See in White Horse Homes
- Shared-stack cross-contamination. White Horse’s 1950s tract ranches were built with single shared masonry stacks serving both the oil boiler and a neighbor’s flue in attached or closely-spaced homes, so a crown or cap failure on one side of the stack lets water and downdraft cross into the adjacent flue. This shared-stack geometry is why cap and crown work here often becomes a two-household conversation, not a one-chimney repair.
- Original clay tile liners spalling beneath intact caps. The clay tile liners in 1950s-70s White Horse stacks are cracking and flaking, so a cap or crown that seals the top still leaves moisture migrating down to failed tile. The cap looks fine. The liner is destroying itself from the inside.
- Oil-to-gas conversion corrosion. Conversions left oversized flues serving a single small gas water heater, producing heavy condensation that corrodes the crown from the inside and rots the mortar bed under any cap. The exterior crown shows no obvious damage until the cap literally sinks into softened mortar.
- Neighbor’s backdraft through crown gaps. Shared and adjacent flues in attached properties mean a neighbor’s appliance backdrafts into your flue when a crown or cap gap breaks the stack’s pressure separation. You smell smoke. Your carbon monoxide detector chirps. The problem is at the top of a chimney you thought was yours alone.

FAQs - Chimney Cap & Crown in White Horse
No. A cap on your flue alone won’t stop backdraft from a neighbor’s appliance if the crown is cracked or the flue separation inside the stack has failed. We inspect the entire stack top, document crown condition with photos, and typically recommend a multi-flue cap that restores pressure separation across both openings. Call (856) 519-0832 - we’ll look at the whole stack, not just your side.
Your oversized flue, originally built for an oil boiler, now vents only a small gas water heater. The low exhaust temperature condenses water vapor against the clay liner and crown, producing acidic moisture that corrodes from the inside. A properly sized cap or liner reduction stops this, but the wrong cap makes it worse by trapping condensation. We see this pattern repeatedly in White Horse’s converted ranches and can specify a solution that matches your actual flue load.
Once a year, every year, before the heating season starts. Mercer County’s freeze-thaw cycle turns minor crown cracks into major spalling over a single winter, and White Horse’s mid-century chimneys have less margin for delay than newer construction. Our $89 Seasonal Tune-Up includes cap, crown, and flue inspection with photos. Call to book before October fills.
Yes. This is a standard configuration in White Horse’s converted oil systems, and catalog caps rarely fit properly. We measure both openings, specify screening appropriate for each flue’s draft requirements, and fabricate a custom cap that prevents cross-contamination while maintaining proper venting. Most custom caps are installed two weeks after measurement.
A Level 2 inspection uses a camera to document the full interior flue and exterior crown condition, producing photos you can see and a plain-English verdict on whether the problem is the cap, the crown, the liner, or a combination. In White Horse’s shared-stack housing, this inspection often reveals that what looked like a simple cap replacement is actually crown failure with liner damage beneath. Nothing is recommended without camera evidence you can review yourself. Call (856) 519-0832 to schedule - estimates are free.
