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.
Fast, Reliable Chimney Cap & Crown Across Yardville
Chimney cap and crown repair in Yardville typically runs $280-$750 for most jobs, with custom multi-flue caps and full crown rebuilds reaching $900-$1,400. Our crews are on the road to Yardville daily from our dispatch office, and we usually book inspections within a few days of your call. If you’re burning wood through Mercer County winters, the condition of your cap and crown isn’t something to guess about - water intrusion and draft failure from a cracked crown or missing cap are the leading causes of chimney damage we see in Yardville’s postwar housing stock.
We’ve been working on Yardville chimneys for decades. We know the Cape Cods off South Broad Street, the split-levels near the Hamilton Township border, and the ranch homes clustered around Yardville’s 08620 zip. These houses were built during the same construction wave, with the same clay-tile flues and the same mortar formulas - and they’re failing on the same schedule now. That’s not a guess. That’s what our cameras show us, season after season. Call (856) 519-0832 to schedule a Level-2 inspection with photos you can see and a plain-English verdict.
Why Hearthstone Chimney Co. Is Yardville’s Preferred Chimney Cap & Crown Company
Yardville homeowners call us because we document what we find. Every Level-2 inspection ends with dated photos and a written verdict - no verbal hand-waving, no pressure to commit on the spot. Our Chimney Cap & Crown team has replaced crowns on dozens of Yardville homes where the previous “repair” was a bucket of sealant slapped on cracked concrete.
We’re not a one-truck operator who might answer the phone next month. Hearthstone Chimney Co. has served local communities for over 42 years, and our phones are staffed by a live person 24 hours a day, 7 days a week - not a callback queue, not an app. When you call (856) 519-0832, you speak to someone who can book your Yardville appointment and tell you what to expect.
Our technicians are background-checked and uniformed, and most cap and crown jobs are completed in a single visit. We give you no-hassle upfront pricing - the number on the estimate is the number on the invoice. And every job is backed by our 90-Day Done Right Promise in writing: if it’s not right, we come back. No arguing, no paperwork chase.
We also understand Yardville’s specific conditions. The freeze-thaw cycles in central New Jersey’s Mercer County are particularly destructive to aging mortar joints and clay tile liners in 1950s-70s masonry chimneys. Water infiltrates micro-cracks, expands on freezing, and accelerates spalling each season. A cap or crown that sheds water properly is not optional here - it’s what keeps your chimney standing.
Our Chimney Cap & Crown Services in Yardville
Crown Repair
Crown repair is our most common call in Yardville, and for good reason. The original crowns on 1950s-1975 masonry chimneys were often poured with too little Portland cement, no reinforcing mesh, and no overhang to shed water. After sixty years of Mercer County freeze-thaw, they’re spalling into loose chunks. We cut out the damaged material, form a new crown with proper slope and a minimum two-inch overhang, and apply a shield coating rated for our climate. A patched crown without proper overhang just traps water - we’ve seen that mistake repeated on Yardville homes, and we don’t do it.

Cap Installation & Cap Replacement
Standard single-flue caps keep out rain, squirrels, and leaves. But many Yardville chimneys need more. If your home still runs an original 8-inch oil flue tile venting a converted gas appliance - and we find this constantly in Yardville’s split-levels and ranches - a basic cap won’t address the condensation problem attacking your chimney from inside. We size caps to the actual flue, not the label on your furnace, and we’ll tell you plainly when the flue itself needs attention before any cap will do lasting good.

Multi-Flue Cap
Multi-flue caps are essential for Yardville homes with shared masonry stacks - common in split-levels where a furnace and fireplace or wood stove vent through the same chimney. On a split-level off Yardville’s South Broad Street area, our tech found the original 8-inch oil flue tile venting a converted gas furnace and a wood stove on a shared masonry stack - the flue liner was coated in glazed third-degree creosote and the chimney crown had spalled into loose chunks from years of freeze-thaw. We fitted a custom multi-flue cap over the two flues, poured a new crowned top with an overhang to shed water off the stack, and shield-coated the crown; the wood stove side dropped from monthly to seasonal buildup once draft and crown were corrected. Multi-flue caps protect the entire stack and eliminate the gap between flues where water pools.

Custom Cap
Yardville’s older masonry chimneys don’t always match modern standard sizes. Flue tiles have shifted, crowns have eroded, and original construction varied even within the same block. We measure on site and order custom caps from Famco and Copperfield to fit your actual chimney - not the nearest catalog size. A cap that doesn’t seat properly is a cap that leaks and blows off in the first winter storm. We do it once, and we do it right.

Crown Coating
For crowns with minor surface degradation but intact structure, a professional-grade crown coating can add years of service. We use flexible, breathable coatings that won’t trap moisture inside the masonry - critical in Yardville’s freeze-thaw environment. We won’t sell you a coating if the crown is structurally failed; we’ll show you the photo and explain why a full repair is the honest call. Photos you can see, a plain-English verdict.

Common Chimney Cap & Crown Problems We See in Yardville Homes
- Crowns with no overhang wick water directly into the flue. Many Yardville masonry chimneys were built with flush crowns that shed poorly. Water runs down the face of the chimney, saturates the brick, and infiltrates the firebox below. A cap swap alone won’t fix this - the crown geometry has to be corrected.
- Original clay-tile flues from the 1950s-70s are cracking from freeze-thaw cycles. Yardville’s repeated freeze-thaw pattern is particularly destructive to aging mortar joints and clay tile liners. A cap-sized fix won’t hold on a chimney crown that’s already fractured and shifting.
- Oil-to-gas conversions left undersized flues producing heavy condensation. Many Yardville masonry chimneys still run an 8-inch oil-era flue tile venting gas or a wood stove. The mismatch produces creosote-like condensation deposits that attack mortar and the crown from inside. The cap and crown need to be evaluated as part of the whole system.
- Previous patch jobs trap moisture and accelerate decay. We’ve peeled off thick layers of roofing tar and generic masonry sealant from Yardville chimneys - well-intentioned DIY repairs that sealed water in rather than out. Proper crown repair requires removal of failed material, not another layer on top.

FAQs - Chimney Cap & Crown in Yardville
No, not safely. The original 8-inch clay flue tile in your Yardville ranch was sized for an oil furnace, and if you’re now venting gas or a wood stove through it, the flue is likely undersized and producing condensation deposits you can’t see from the ground. We need a Level-2 camera inspection to verify flue condition before any cap installation. Call (856) 519-0832 to schedule - estimates are free.
Yes, significantly faster. Wood stoves in Yardville’s split-levels often vent through the original oil-era flue tile, which is too large for modern gas but can be too small or poorly drafted for wood burning. The result is incomplete combustion and glazed creosote buildup. We regularly find third-degree creosote in these setups. Proper cap and crown geometry improves draft, but the flue sizing must also be evaluated. Call for an inspection before the next burning season.
The cap may need resizing, and the crown almost always needs evaluation. Gas appliances produce cooler, wetter exhaust that condenses in an oversized flue - the 8-inch oil tile we find constantly in Yardville. That condensation attacks mortar joints and the crown from inside. A cap that fit the oil setup may be wrong for gas, and a crown with internal moisture damage will fail regardless of surface patching. We assess the whole system.
For active wood burning in Yardville, we recommend annual Level-2 inspection with camera documentation. Mercer County’s freeze-thaw cycles accelerate damage, and Yardville’s 1950s-75 chimneys are reaching critical age. If you’re burning daily through winter, mid-season checks for creosote buildup are prudent - especially if you’re on an original oil-era flue tile. The 90-Day Done Right Promise backs every job we do.
Because patching without addressing the root cause is temporary at best. Yardville crowns crack from freeze-thaw water infiltration, often compounded by gas condensation from an undersized flue and by crowns that were originally poured without proper slope or overhang. Another layer of sealant traps more moisture. We remove failed material, reform the crown with correct geometry, and apply a breathable shield coating - done right, and we stand behind it.
