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 Staten Island
Chimney cap and crown repair in Staten Island typically runs $340-$890 depending on whether you need a cap replacement, crown coating, or full rebuild, and most jobs are completed in a single visit. If you’re seeing water stains on the ceiling near your fireplace, rust flakes in the firebox, or smoke from a neighbor’s unit drifting into your home, the cap or crown is the first place our Chimney Cap & Crown team looks.
We’ve been dispatching crews for Staten Island Chimney Cleaning & Sweep from our New York City office for decades. We know the tight blocks of Stapleton and St. George where roof access means navigating between attached Victorians, and we know the South Shore neighborhoods where post-Sandy rebuilds are hitting their first real maintenance cycle. Our phone - (516) 613-3035 - is answered by a live person, 24 hours a day, every day. No voicemail. No callback queue.
Why Hearthstone Chimney Co. Is Staten Island’s Preferred Chimney Cap & Crown Company
Staten Island is not like the other four boroughs, and a technician who treats it that way will miss things that cost you thousands later. We’re the only NYC borough where single-family homeownership dominates, which means we have the highest concentration of active wood-burning fireplaces per capita by a wide margin - exactly why our Fireplace Services in Staten Island stay busy year-round. It also means our chimneys sit exposed to salt-laden air from New York Harbor, the Kill Van Kull, and the Arthur Kill - a combination that corrodes metal caps and spalls mortar crowns at rates that simply don’t apply in Queens or the Bronx.
Our reputation here was built on documenting what we find. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your crown can wait a season, we’ll say so. If it’s actively funneling water into your flue, we’ll show you exactly where. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we make it right, no arguing, no paperwork chase.
Calls are answered by a live person 24/7. Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most cap and crown jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Staten Island
Cap Installation
New cap installation in Staten Island runs $280-$520 for standard single-flue stainless or galvanized models, and $590-$1,150 for custom multi-flue systems with separate bays. On the North Shore, we regularly install caps on original brick chimneys in St. George and New Brighton that have never had proper protection - just a terra cotta flue tile sticking above a crumbling crown. A correctly sized cap with a minimum 5-inch skirt and animal-proof mesh stops water, squirrels, and downdrafts before they become expensive problems.
Cap Replacement
Chimney Repair in Staten Island often starts with replacing a failed cap, which runs $240-$480 for standard sizes, though salt-air corrosion often means the chase cover beneath is pitted too. We see this constantly on South Shore homes in Great Kills and New Dorp Beach, where galvanized chase covers installed in the 1990s or early 2000s have simply dissolved. We stock replacement caps and chase covers from Gelco and Olympia Chimney, so we’re not ordering parts and making you wait. Most replacements are done same visit.
Crown Repair
Crown repair in Staten Island typically ranges from $420 for targeted patching to $1,200 for full rebuilds on large multi-flue stacks. The salt air here finds every hairline crack and freeze-thaw cycle widens them into channels that direct water straight down the flue. On a tight block in Stapleton, we answered a call about a neighbor’s fireplace smoke backing up into an adjacent unit. Our tech found a shared multi-flue stack with an original brick crown that had spalled open from salt air, and the neighbor’s furnace was venting into the same flue. We installed a custom multi-flue cap with separate bays and a copper crown coating, restoring proper draft and stopping the cross-contamination.
Crown Coating
Crown coating in Staten Island runs $340-$580 and is one of our most important preventive services here. The salt-laden environment means even sound crowns benefit from a flexible, waterproof membrane every 5-7 years - sooner if you can see surface pitting or map cracking. We use professional-grade crown coatings from Heatshield in Staten Island and Copperfield, applied after thorough surface prep. On chimneys that have already begun spalling, coating buys time and stops further degradation. For post-Sandy rebuilds in Midland Beach and Oakwood Beach, where general contractors often skipped proper crown finishing, this service can add a decade of life to an otherwise vulnerable chimney.
Multi-Flue Cap
Multi-flue caps for Staten Island’s shared and adjacent flue systems run $640-$1,280 depending on dimensions and whether we need to fabricate separate draft bays. Many North Shore Victorians in Port Richmond and Stapleton were built with multi-flue stacks serving two or three attached units. A standard single-flue cap on one flue leaves the others exposed, and a poorly designed multi-flue cap can create pressure imbalances that cause backdrafting. We measure each flue’s draft characteristics and specify caps that maintain proper separation.
Custom Cap
Custom caps for unusual flue configurations, historic preservation requirements, or severe exposure conditions start at $780 and typically cap out around $1,450. We’ve fabricated custom solutions for copper-roofed homes in Tottenville and oversized Rumford fireplaces in historic Stapleton renovations. Every custom cap is measured on-site, fabricated from appropriate gauge material, and installed with proper counter-flashing.

Trusted Brands We Service in Staten Island
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in our salt-air environment. For cap and crown work in Staten Island, we stock and install DuraFlex liner and cap components, HeatShield crown coating systems, and Gelco and Olympia Chimney multi-flue and custom cap products. These are the brands specified by technicians who understand that a cap that holds up in Schenectady may not survive five Staten Island winters. Having the right parts on the truck means we complete most jobs in a single visit, and our pricing reflects that efficiency.
Common Chimney Cap & Crown Problems We See in Staten Island Homes
- Original multi-flue brick crowns in North Shore Victorians spall and crack from salt-laden air. In St. George and New Brighton, we regularly find century-old crowns where the mortar surface has simply exploded off the brick substrate, creating channels that funnel water down shared flues and allow cross-contamination between adjacent units.
- Post-Sandy prefab chase systems in South Shore homes have improperly flashed caps. Chimneys rebuilt in Midland Beach and New Dorp Beach in 2013-2015 by general contractors often used cheaper prefab chase covers with inadequate side clearance or missing storm collars. Water infiltrates even on chimneys that look new from the street.
- Galvanized or stainless chase covers pit and corrode rapidly in persistent salt air. What should be a 20-year stainless cover in an inland climate may show through-pitting in 8-10 years here. We find loose caps that lift in nor’easters and freeze-thaw cycles, then admit driving rain directly onto the flue.
- Shared flue stacks without proper separation create dangerous cross-contamination. When one unit’s furnace or water heater vents into a flue that another unit uses for fireplace exhaust, and the crown has failed, combustion gases can enter living spaces. We always bring a camera and moisture meter on North Shore calls to verify flue separation.

FAQs - Chimney Cap & Crown in Staten Island
Yes, especially if you share a multi-flue stack common in North Shore neighborhoods like Stapleton or St. George. When the crown spalls open or a multi-flue cap is missing or improperly designed, smoke and combustion gases from one flue can migrate into an adjacent flue and down into your fireplace or furnace return. We verify this with a Level-2 camera inspection that shows you exactly where the breach occurs. Call (516) 613-3035 - estimates are free.
Salt-laden air from the harbor and kills accelerates mortar surface degradation by a factor of roughly two compared to inland NYC neighborhoods. Freeze-thaw cycles acting on salt-compromised crown surfaces open cracks faster, and once water reaches the reinforcing wire, rust expansion spalls the concrete from within. We recommend crown inspection every 2-3 years here versus every 5 years in the Bronx or upper Queens. Call (516) 613-3035 to schedule.
General contractors in 2013-2015 often installed galvanized or light-gauge stainless caps without adequate side clearance or proper storm collars, and the salt air here pits even decent stainless in 5-7 years. We find this routinely in Midland Beach, New Dorp Beach, and Oakwood Beach. A “young” chimney can have active water infiltration that the homeowner doesn’t suspect. Our camera inspection and moisture meter tell the real story. Call (516) 613-3035 for an exact assessment.
You can, but it’s often not the best solution for shared stacks. Separate single-flue caps leave gaps where water enters the chase, and they don’t address pressure imbalances that cause backdrafting. We typically recommend a custom multi-flue cap with separate internal bays that maintains proper draft separation while protecting the entire stack. The cost difference is usually $150-$300 versus multiple single caps, and the performance is significantly better. Call (516) 613-3035 for a measurement.
Look for map cracking (fine surface cracks in a grid pattern), spalling (flaking or popping of the mortar surface), rust stains on the brick below the crown, or water in the firebox after rain. On Staten Island, salt damage often shows first as a whitish powder (efflorescence) where moisture is drawing salts through the crown. If you can see bare metal lath or rebar, the crown is in active failure and needs immediate attention. We document everything with photos during our free estimate. Call (516) 613-3035.
