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.

AfterTrusted Chimney Cap & Crown for New City Homeowners
A properly fitted chimney cap and sound crown in New City typically costs between $280 and $950 depending on whether you’re replacing a rusted cap or rebuilding a cracked crown, and most jobs are completed in a single visit. We’ve been doing this work in Rockland County since 1984, and we’ve learned that water is the enemy that never sleeps, especially through our freeze-thaw winters.
At Hearthstone Chimney Co., we’ve spent over 42 years watching what happens when New City homeowners skip this protection. The crown is the concrete slab that seals the top of your chimney. The cap sits above it, keeping rain, squirrels, and leaves out of the flue. Together they form the roof over your roof, and when either one fails, water gets into places that cost ten times more to fix. We’ve replaced fireboxes in Valley Cottage homes that were destroyed because a $400 cap was never installed. We’ve rebuilt chimney shoulders in Congers where crown cracks let water freeze and expand until the brick face spalled off entirely.
Our technicians carry professional-grade materials from Olympia Chimney, Famco, and Copperfield on every truck. We document every inspection with photos you can see and a plain-English verdict. Our pricing is upfront, the number on the estimate is the number on the invoice, and everything we do is backed by the 90-Day Done Right Promise in writing. If you’re noticing rust streaks on your chimney, water in the firebox, or hearing animals in the flue, call us at (845) 599-0930. A live person answers 24 hours a day, and we’ll give you a free, no-obligation estimate.
What Our Chimney Cap & Crown Service Includes
Cap Installation
Cap installation is the first defense for a chimney that has never had one or where the original has gone missing. In New City, we see this most often on homes built in the 1960s and 1970s where caps were never standard, or where a previous owner removed a damaged cap and never replaced it. Without a cap, rain enters the flue directly, mixing with creosote to form acidic compounds that corrode metal liners and eat away at mortar joints. We measure your flue precisely, select a cap from our stock of Olympia Chimney and Famco models, and secure it with stainless steel fasteners that won’t rust out in five years. Most installations take under an hour, and we check draft performance before we leave to make sure the cap’s screening doesn’t restrict airflow.
Cap Replacement
Cap replacement becomes necessary when the existing unit has rusted through, been damaged by falling branches, or was never the right size to begin with. A common problem in New City is the cheap galvanized cap that a previous installer sourced from a hardware store, which rusts out in three to four years and leaves orange streaks down the brick. We remove the old cap, inspect the flue and crown beneath it for hidden damage, and install a replacement in stainless steel or copper that matches your flue count and dimensions. Our trucks carry multiple sizes, so we rarely need to order and return. The replacement is sealed properly, and we photograph the before and after for your records.
Crown Repair
Crown repair addresses cracks and deterioration in the concrete slab that caps the chimney structure itself. In New City, crown damage accelerates when water seeps into hairline cracks, freezes overnight during our January cold snaps, and expands the crack wider each cycle. We’ve repaired crowns in Upper Nyack where the homeowner thought they needed a full rebuild, but our camera inspection showed the crack hadn’t yet reached the interior edge. We clean the crown surface, route out loose material, and apply a specialized crown repair compound that bonds to existing concrete and remains flexible enough to handle thermal movement. For crowns with more extensive damage, we may form and pour a new cap over the existing structure, saving the cost of full demolition.
Crown Coating
Crown coating is a preventive treatment for crowns that are sound structurally but showing early surface wear and minor cracking. This is ideal for New City homeowners whose crowns are five to fifteen years old and haven’t yet failed, but where the concrete is porous and absorbing water. We apply a flexible, waterproof coating, typically from the HeatShield or Copperfield product lines, that seals the surface and bridges small cracks before they widen. The coating is brushed or troweled on in two coats, and it cures to a finish that sheds water rather than absorbing it. This service costs significantly less than crown repair or replacement, and it can add a decade of life to a crown that would otherwise be rebuilding in five years.
Multi-Flue Cap
Multi-flue cap installation covers chimneys with two or more flues exiting the same structure, common in New City homes with a fireplace and a separate furnace or water heater venting together. A single large cap protects all flues more effectively than individual caps, which can leave gaps where water runs down between them. We measure the full chimney top, fabricate or select a multi-flue cap with proper clearance heights for each flue, and anchor it to the chimney sides with stainless steel straps or masonry anchors. The design includes separate screening for each flue to prevent cross-drafting, and the slope of the lid directs water away from the center. This is a permanent solution that eliminates the problem of mismatched individual caps failing at different times.
Custom Cap
Custom cap fabrication is for chimneys with unusual dimensions, decorative features, or historical requirements that standard caps cannot accommodate. In Briarcliff Manor and Sleepy Hollow, we’ve built custom caps for pre-war chimneys with curved tops or ornate brickwork that a box-store cap would destroy visually. We take precise field measurements, often working with copper or stainless steel from Copperfield or Olympia Chimney suppliers, and fabricate a cap that fits exactly and complements the home’s architecture. The custom work includes proper ventilation calculations, durable fastening that doesn’t penetrate decorative elements, and a finish that weathers appropriately. These caps cost more than standard units, but they last decades and protect chimneys that would otherwise be impossible to cap properly.

Brands We Service for Chimney Cap & Crown
We’ve worked with Olympia Chimney products for over fifteen years, and their stainless steel caps hold up particularly well in the salt-air influence we get from the Hudson River in communities like Nyack and Haverstraw. Their multi-flue models come with reinforced lids that don’t oil-can in high winds, and we stock their most common sizes so replacement is immediate. Famco caps are our go-to for custom and odd-size applications; their fabrication quality means we can specify exact dimensions and get a cap that fits without field modification. We’ve installed hundreds of Famco units in New City and the surrounding towns, and their galvanized and powder-coat finishes resist the streaking that cheaper caps show after two seasons.
Copperfield supplies our crown repair materials and specialized coatings, including the flexible compounds we use when a full crown pour isn’t necessary. Their products bond to weathered concrete better than generic hardware-store alternatives, which matters when we’re working on a 1970s chimney crown that has seen forty New City winters. Whether you have an Olympia Chimney, Famco, or Copperfield product already installed, or any other make, we can service it, replace it, or improve on it with components that meet the same standard.
Signs You Need Chimney Cap & Crown Right Now
- Rust stains running down your chimney brick or siding. These streaks mean your galvanized cap is failing and depositing iron oxide every time it rains. The rust doesn’t just look bad, it signals that the cap metal is thinning and will soon develop holes that let water straight into the flue. We’ve replaced caps in Hillcrest where the rust had eaten through entirely and the homeowner didn’t know until water damaged their firebox.
- Water in the firebox or damp odors even when it hasn’t rained recently. This means water is entering the flue and pooling in the smoke chamber or damper area, then evaporating slowly enough to leave a musty smell. In New City’s humid summers, this moisture breeds mold and deteriorates the damper mechanism. A sound cap and crown should keep the flue dry enough that you never see this.
- Visible cracks in the crown concrete, especially at the edges or around the flue. Crown cracks are progressive. What starts as a hairline in October widens through winter freeze cycles until water reaches the brick courses below. We’ve seen crowns in New Square that looked fine from the ground but had cracks wide enough to slide a quarter into, with water damage already working through the chimney structure.
- Animals or nesting debris in the flue. Squirrels, raccoons, and starlings enter uncapped chimneys readily, and once inside they build nests that block draft and create fire hazards. A properly screened cap prevents this entirely. We removed a starling nest from a Congers chimney last spring that had been growing for two years because the cap had blown off in a storm and no one noticed.
- Spalling brick or deteriorating mortar on the upper chimney courses. When the crown fails to shed water properly, moisture soaks into the top brick rows and freezes. The face of the brick pops off, mortar crumbles, and the chimney structure weakens. This damage always starts at the top and works down, which means the crown was the original failure point. Addressing the crown early prevents the rebuild that spalling eventually requires.

How Much Does Chimney Cap & Crown Cost in New City?
A standard stainless steel cap installation in New City typically runs $280 to $450, depending on flue size, number of flues, and whether we need to remove an old, seized cap first. For full details, see our Chimney Cap & Crown cost guide. Cap replacement where the existing unit is rusted or damaged falls in the same range, though multi-flue caps or custom sizing can push toward $650 to $950. Crown coating as preventive maintenance is usually $350 to $550, while crown repair for cracked but structurally sound crowns runs $450 to $850. Full crown rebuilds, where we form and pour new concrete, range from $800 to $1,800 depending on chimney dimensions and access difficulty.
Several factors move the price within these ranges. Chimney height and roof pitch affect how we access the work; a two-story steep roof in Upper Nyack takes longer to rig safely than a ranch in Valley Cottage. The condition of what’s beneath the cap matters too. If we remove a rusted cap and find the crown underneath is crumbling, we’ll show you the photo and explain before adding crown work to the scope. Material choice affects cost as well. Copper caps last longer and weather beautifully, but they cost more than stainless steel. Galvanized steel is cheapest upfront and most expensive over time because it rusts out and needs replacement.
The best way to avoid overpaying is to get an inspection that shows you exactly what condition your cap and crown are in, rather than guessing from the ground. Some companies quote cap replacement over the phone without looking, then arrive and discover the crown is the real problem, doubling the bill. We don’t do that. Our free estimate includes the camera inspection and photos, so you know what you’re paying for before you decide. We also offer a Free Second Opinion on any written estimate you’ve received elsewhere, and a permanent 5% Senior and Veteran discount applies to all cap and crown work.

Frequently Asked Questions - Chimney Cap & Crown in New City
The crown is the sloped concrete slab that covers the top of your chimney structure, directing water away from the flue and protecting the brick courses below. The cap is the metal cover that sits above the crown, shielding the flue opening from rain, animals, and debris while allowing smoke to exit. You need both because the crown protects the chimney itself, while the cap protects the flue interior; one without the other leaves a gap in your defense against water damage. In New City’s climate, where we see freeze-thaw cycles from November through March, both components are essential to prevent the costly deterioration that water causes.
Most cap installations and replacements are completed in under two hours, and crown coatings typically take two to three hours including surface preparation and cure time. Crown repairs or rebuilds can take four to six hours depending on the extent of damage and whether we need to form and pour new concrete.

Yes, we work with all three brands regularly and stock common cap sizes and crown repair materials from each. Olympia Chimney and Famco are our primary cap suppliers, and Copperfield provides our crown coatings and repair compounds. If you already have one of these brands installed, we can service, replace, or upgrade it with matching or improved components. Even if your cap or crown is from a different manufacturer, we can help, our technicians carry the tools and materials to adapt to most configurations.
A missing or failed cap is urgent if you’re in burning season or expecting heavy rain, because water and animals enter immediately. Crown cracks are less urgent in dry weather but accelerate rapidly once freeze-thaw cycles begin. During our inspection, we’ll show you photos and tell you honestly whether the work can wait six months or needs attention now. We’ve told New City homeowners their crown could wait until spring, and we’ve shown others why delaying would cost them a rebuild. Call (845) 599-0930 and we’ll give you a straight assessment.
All our cap and crown work is covered by the 90-Day Done Right Promise, backed in writing with no paperwork and no arguing. If anything about the installation or repair isn’t right, we come back and make it right at no charge. Beyond our guarantee, the materials themselves carry manufacturer warranties that vary by product, stainless steel caps typically have longer coverage than galvanized. We’re in this for the long haul, we’ve been serving local communities for over 42 years and we plan to be here when you need us next.
Clear a path to your fireplace or stove so our technician can access the flue for the camera inspection, and make sure we can reach your roof safely, which usually means moving vehicles or patio furniture that blocks ladder placement. You don’t need to clean the fireplace or climb up to look at anything yourself. We’ll handle the inspection, photography, and explanation. If you have previous inspection reports or invoices from other companies, those can be helpful, but they’re not required. Call (845) 599-0930 to schedule, and we’ll confirm everything when we call the day before.
