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.

Chimney cap and crown work in Rockville Centre typically runs $280 to $1,850 depending on whether we’re installing a standard cap, rebuilding a cracked crown, or fitting a custom multi-flue cover. Most jobs are completed in a single visit with upfront pricing agreed before we start. Call (631) 498-8835 for a free estimate with photos you can see and a plain-English verdict.
We’ve been working on chimneys in Rockville Centre and nearby Nassau County communities for over 42 years. In that time, we’ve learned what the salt air off the Atlantic does to concrete crowns, how the freeze-thaw cycles in Lakeview and Island Park split mortar, and why a poorly fitted cap in Baldwin or Oceanside turns into a $3,000 rebuild. Russell Haines started Hearthstone Chimney Co. in 1984 with a simple standard: document the problem, explain it plainly, fix it right, and stand behind it. That standard hasn’t changed. Our technicians are background-checked and uniformed, and a live person answers our phone 24 hours a day, 7 days a week. No voicemail. No callback queue.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is the metal cover that sits atop your flue, keeping rain, animals, and debris out while letting smoke escape. In Rockville Centre, we see too many uncapped chimneys after squirrels nest or rain washes down the flue and rusts out the damper. We measure your flue precisely and install professional-grade caps from Famco and Copperfield, secured with stainless steel fasteners that won’t corrode in coastal air. Most installations take under an hour, and we verify proper draft before we leave.
Cap Replacement
Caps rust, blow off in nor’easters, or get damaged by falling branches. If your cap is missing, rattling, or visibly corroded, water is already getting in. We remove the old cap, inspect the flue tile and crown beneath for hidden damage, and fit a replacement that matches or exceeds the original spec. In neighborhoods like East Rockaway and South Hempstead, we’ve replaced hundreds of caps after storms, and we carry common sizes so you’re not waiting on a special order.
Crown Repair
The crown is the concrete slab that seals the top of your chimney between the flue tiles. When it cracks, water seeps into the brickwork below, and in Rockville Centre’s freeze-thaw climate, those cracks widen every winter. We grind out deteriorated concrete, apply a bonding agent, and pour new crown material sloped to shed water. For minor cracking, we may use HeatShield crown coating as a preventive measure. We always photograph the damage before and after, so you see exactly what was wrong and how we fixed it.
Crown Coating
Not every cracked crown needs a full rebuild. If the concrete is structurally sound but weathered, a professional crown coating extends its life by 10 to 15 years. We clean the surface, fill hairline cracks, and apply a flexible, waterproof membrane formulated for chimney crowns, not generic masonry sealer. This is popular in Garden City and Mineola, where homeowners with well-maintained older homes want to protect their investment without unnecessary reconstruction. The coating cures in 24 hours and carries our 90-Day Done Right Promise.
Multi-Flue Cap
Homes with multiple fireplaces or a fireplace and furnace sharing one chimney need a multi-flue cap that covers all flues in a single structure. These are larger, heavier, and require precise measurement and secure mounting to handle Long Island wind loads. We fabricate and install multi-flue caps with screened sides to keep out animals and wind-driven rain. In West Hempstead and Lakeview, we’ve fitted multi-flue caps on everything from 1920s colonials to newer construction with multiple gas inserts.
Custom Cap
Some chimneys don’t fit standard sizes: oversized flues, unusual shapes, or historic properties where the cap must match architectural detail. We measure on-site, specify the gauge and finish, and work with our suppliers to deliver a cap that fits precisely and looks right. Copper and black galvanized are common choices in Rockville Centre’s historic districts. A custom cap costs more than off-the-shelf, but it lasts longer, fits better, and doesn’t leave gaps where water gets in.

Brands We Service for Chimney Cap & Crown
We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind ours. Famco stainless steel caps are our go-to for standard flues in coastal environments; we’ve installed hundreds across Rockville Centre, Hempstead, and Oceanside, and we stock their most common sizes so replacement is fast. Copperfield supplies our custom and decorative caps, including copper finishes that weather to a natural patina and hold up against Nassau County’s salt air for decades. Their mounting hardware is engineered for wind resistance, which matters when you’re three miles from the Atlantic.
DuraFlex and HeatShield provide the crown repair and coating systems we use for concrete restoration and preventive sealing. We’ve applied HeatShield crown coating on chimneys from Baldwin to Long Beach, and we know exactly how thick it needs to go and how long it needs to cure before the first rain. Whether you have a Famco cap already installed, a Copperfield custom cover, or any other make, we can service it, replace it, or improve it. We don’t limit our work to one brand, and we don’t substitute builder-grade materials to save a few dollars.
Signs You Need Chimney Cap & Crown Right Now
- Water stains on the ceiling near your fireplace. This means moisture is getting past the cap or crown and running down the flue into your home. In Rockville Centre’s older homes around the village center, we’ve traced ceiling stains to cracked crowns that have been leaking for two or three seasons before the drywall shows it. The longer it runs, the more expensive the repair.
- Rust on the damper or firebox. Rust means water is entering from above, and the cap is either missing, damaged, or poorly fitted. A rusted damper won’t open fully or seal properly, which costs you heat and creates a fire hazard. We replace the cap and assess whether the damper can be salvaged or needs replacement.
- Visible cracks or spalling on the crown. Concrete crowns crack from thermal stress and freeze-thaw cycles. Once water gets in, it expands when it freezes, popping off chunks of concrete and exposing the brick below. In South Hempstead and Island Park, we see this accelerate after harsh winters. Crown coating can stop early-stage cracking; waiting means a full rebuild.
- Animals or nesting debris in the flue. Squirrels, raccoons, and birds enter uncapped chimneys readily. If you hear scratching or smell decay from your fireplace, the cap is missing or has a damaged screen. We remove the obstruction, inspect for damage, and install a proper cap with animal-proof mesh.
- The cap is missing or visibly damaged after a storm. High winds off the South Shore rip off poorly secured caps regularly. If yours is gone, your flue is open to every rainstorm until you replace it. We secure our caps with stainless steel fasteners and proper mounting brackets, not the friction-fit or cheap screw methods that fail in the first nor’easter.

On-site inspection with camera documentation. Our technician arrives in a marked vehicle, uniformed and background-checked.

You get photos you can see and a plain-English verdict.

How Much Does Chimney Cap & Crown Cost in Rockville Centre?
A standard cap installation in Rockville Centre typically runs $280 to $450, including the cap, fasteners, and labor. See our Chimney Cap & Crown cost guide for full pricing details. Cap replacement on an existing mount falls in the same range unless the flue tile or crown beneath is damaged. Crown coating for preventive maintenance or minor crack repair runs $450 to $750 depending on chimney size and accessibility. Full crown rebuilds, where we remove deteriorated concrete and pour new, range from $950 to $1,850. Custom caps, especially in copper or with multi-flue coverage, start around $650 and run to $1,400 or more based on dimensions and material.
Several factors move the price. Chimney height and roof pitch affect ladder and scaffolding needs. Hidden damage beneath a cracked crown, such as deteriorated brick or compromised flue tiles, must be addressed for the repair to last. Custom fabrication and premium materials like copper cost more than galvanized steel but last significantly longer in Nassau County’s coastal environment.
The best way to avoid overpaying is to get a documented inspection with photos before agreeing to any work. We’ve given free second opinions on written estimates from other companies in Rockville Centre, Hempstead, and Oceanside, and we’ve often found that recommended crown rebuilds could be handled with coating, or that a quoted custom cap was unnecessary. Our estimates are free, detailed, and come with no obligation. The number we give you is the number on the bill.

Frequently Asked Questions - Chimney Cap & Crown in Rockville Centre
Chimney cap and crown work covers the protective components at the top of your chimney. The cap is a metal cover that keeps rain, animals, and debris out of the flue. The crown is the concrete slab that seals the chimney top and sheds water away from the brickwork. Together they prevent the single largest cause of chimney deterioration: water intrusion. At Hearthstone Chimney Co., we inspect both as a system, because a new cap on a cracked crown just hides the real problem.
Most cap installations and replacements are completed in under two hours. Crown coating takes three to four hours including surface prep and cure time assessment. A full crown rebuild typically requires a full day, with a 24- to 48-hour cure before the chimney can be used. We schedule accordingly and confirm timing when we provide your upfront estimate. Call (631) 498-8835 to book - most jobs are done in a single visit.
Standard cap installation runs $280 to $450, crown coating $450 to $750, full crown rebuild $950 to $1,850, and custom or multi-flue caps $650 to $1,400-plus. The exact price depends on chimney size, accessibility, material choice, and whether hidden damage is found beneath the crown. We provide free estimates with photos and line-item pricing so you know exactly what you’re paying for. Call (631) 498-8835 for your exact quote.
Yes. We install, replace, and repair caps from Famco, Copperfield, and all other professional-grade manufacturers. We stock common Famco sizes for fast replacement, and we fabricate custom Copperfield caps to precise measurements. We also work with DuraFlex and HeatShield for crown repair and coating systems. If you have a specific brand already installed, we can match it or recommend an upgrade based on condition and your budget.
Active water intrusion should be addressed promptly to prevent further damage, though it rarely requires middle-of-the-night dispatch. If you have water staining, rust, or visible leaks during rain, call us and we’ll schedule the earliest available inspection. A live person answers 24 hours a day, 7 days a week. We prioritize water-related calls and carry materials to complete most repairs on the first visit, including temporary measures if weather prevents full work.
All our cap and crown work is covered by the 90-Day Done Right Promise, in writing with no arguing. If anything we install or repair fails due to our workmanship within 90 days, we return and make it right at no charge. Manufacturer warranties on materials vary by brand and product line, and we pass those through to you with documentation.

Clear a path from your driveway or street to the chimney area, and move any vehicles or furniture that blocks ladder access. If you have pets, secure them during the visit. You don’t need to clean the fireplace or flue beforehand; that’s our job. Have any previous inspection reports or estimates available if you’d like us to review them. We’ll handle the rest, including roof access, documentation, and cleanup.
