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.
Trusted Chimney Cap & Crown for Flushing Homeowners
Our Chimney Cap & Crown - Flushing repair service typically costs $180 for a basic cap replacement up to $1,800 for full crown rebuilds, with most standard jobs completed in a single visit. A properly fitted cap and intact crown keep water, animals, and debris out of your flue, which is why we treat these as structural repairs, not accessories. If you’re seeing rust streaks on your brickwork or hearing squirrels overhead, the fix is usually straightforward and same-day.
We’ve been working on Queens chimneys since 1984 - over 42 years now - and we’ve learned that Flushing’s older housing stock, from the detached homes near Kissena Park to the attached brick rows off Main Street, faces a specific set of problems that our Chimney Cap & Crown - College Point neighbors know well too. The freeze-thaw cycles here are hard on poured-concrete crowns. Tree canopy is heavy, so leaves and twigs clog uncapped flues. And the squirrels in Flushing? They’re relentless. We’ve pulled nests from chimneys on 35th Avenue, Bowne Street, and everywhere between.
Our technicians are background-checked and uniformed, and most cap and crown jobs are finished in one visit with no-hassle upfront pricing. The estimate we give is the invoice you pay. Every repair is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. Russell Haines has built this company on that standard since day one.

What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is a metal cover that sits atop your flue, screening out rain, animals, and debris while letting smoke escape. You need one if your flue is open to the sky, which means every rainfall sends water directly down your chimney and every nesting season invites squirrels, raccoons, or starlings. At Hearthstone Chimney Co., we measure your flue precisely - single or multi-flue - and install caps from Gelco and Olympia Chimney in stainless steel or copper, secured with proper mounting brackets that won’t lift in a Queens windstorm. We see too many “installed” caps held on with a few sheet-metal screws that rattle loose within a season. Ours stay put.

Cap Replacement
Cap replacement becomes necessary when the existing cap is rusted through, blown off in a storm, or was never the right size to begin with. A loose cap is worse than no cap - it traps moisture against the flue liner and can block draft partially, sending smoke back into your living room. We remove the old cap without damaging your crown, inspect the flue opening for hidden deterioration, and fit a replacement that matches your flue dimensions exactly. In Flushing, where many homes were built with generic “one-size-fits-all” caps in the 1970s and 80s, we find the majority are undersized or improperly mounted. We document the condition with photos before and after, and you’ll see them.

Crown Repair
The crown is the concrete slab that tops your chimney, sloped to shed water away from the flue. Cracks in the crown are the single most common entry point for water damage in Flushing chimneys we’ve inspected. Once water penetrates, it freezes, expands, and opens the crack wider with every winter - and Flushing winters are hard enough to do real damage. We repair crowns using professional-grade crown coat materials from HeatShield, formulated to bond with existing concrete and flex slightly with temperature swings. For cracks under a quarter-inch, we clean, fill, and seal. For more extensive damage, we may recommend partial rebuild. We never suggest work you can’t see: our Level-2 camera inspection shows you the interior condition, and our photos show you the exterior.

Crown Coating
Crown coating is a preventive treatment for crowns that are sound structurally but showing early weathering - fine hairline cracks, surface pitting, or loss of the original slope. Think of it as waterproofing before the leak starts. We apply a flexible, breathable sealant designed for chimney crowns, not generic masonry paint that traps moisture. The coating fills micro-cracks, restores water-shedding slope, and extends the crown’s service life by years. In Flushing, where many crowns were poured with standard concrete mix rather than the harder, air-entrained concrete specified for freeze-thaw zones, this treatment is often the difference between a $400 coating and a $2,000 rebuild down the road. We assess honestly: if the crown is too far gone, we’ll tell you plainly.

Multi-Flue Cap
Multi-flue caps cover two or more flues with a single structure, common in homes with both a fireplace and a furnace or water heater venting through the same chimney. These require precise measurement and proper clearance - too low, and you restrict draft; too small, and you leave gaps for water and animals. We fabricate and install multi-flue caps from Gelco and Copperfield with adequate height above each flue opening and proper mesh spacing to stop animals without clogging with creosote. In Flushing’s older two-family homes and converted properties, we often find improvised multi-flue setups that create dangerous draft interference. We fix them correctly, with documented clearances.

Custom Cap
Custom caps are built for chimneys with unusual dimensions, historical requirements, or aesthetic preferences - oversized flues, corbelled brick tops, or homeowners who want copper that weathers to match their roof flashing. We measure on-site, fabricate to specification, and install with the same mounting integrity as our standard caps. Flushing has a surprising range of architectural styles, from the Victorian-era homes near Flushing Town Hall to mid-century ranches in the northern reaches, and we’ve built custom solutions for all of them, just as we do for our Chimney Cap & Crown - Whitestone customers. Custom work takes longer to fabricate, but the installation itself is still typically completed in one visit once the cap is ready.

Brands We Service for Chimney Cap & Crown
We work exclusively with professional-grade materials from manufacturers that stand behind their products the way we stand behind ours. Gelco caps are our go-to for stainless multi-flue and single-flue installations - we’ve fitted hundreds across Queens, and we keep their standard sizes in stock for faster turnaround. Their mesh design resists creosote buildup better than the builder-grade caps we replace, which matters in Flushing where many homeowners burn regularly through the heating season.
Olympia Chimney supplies our standard galvanized and stainless caps for straightforward replacements, and their dimensional consistency means we rarely need return visits for fit issues. HeatShield crown coating is our choice for preventive crown work - we’ve applied it to dozens of Flushing chimneys and tracked the results over multiple freeze-thaw cycles. It holds. DuraFlex and Copperfield round out our inventory for specialty and custom applications. Whether you have a Gelco cap that needs replacing, an Olympia Chimney unit that’s rusted through, or any other make, we can help. We don’t require you to use our brands for replacement, but we won’t install anything we wouldn’t put on our own homes.
Signs You Need Chimney Cap & Crown Right Now
- Rust stains running down your brickwork. Orange or brown streaks on the chimney exterior mean your cap is rusting through or missing entirely, and water is hitting the metal flue liner or damper assembly. Left unaddressed, this water reaches the firebox and rusts out the damper, turning a $250 cap replacement into a $900 damper job.
- Animals or nesting sounds in the flue. Squirrels, raccoons, and starlings can enter an uncapped flue in minutes. We removed a squirrel nest from a Flushing chimney on Parsons Boulevard last spring that had completely blocked the flue - the homeowner smelled smoke backing up into the bedroom. A proper cap with animal-proof mesh prevents this entirely.
- Cracks or pieces missing from the crown. Stand in your yard and look at the top of your chimney. If the concrete slab is cracked, crumbling, or missing chunks at the edges, water is entering the chimney structure. In Flushing’s freeze-thaw climate, a cracked crown in October becomes a rebuilt crown by March.
- Water in the firebox or rust on the damper. Dry fireboxes stay dry. If you see puddles after rain, or if your damper is rusted and sticks, water is coming down from above. The cause is almost always a missing, damaged, or improperly fitted cap, or a failed crown. We find and fix the source, not just the symptom.
- Draft problems or smoke smell when it rains. A cap that is too small, too low, or partially blocked can create downdraft conditions, especially in Queens where prevailing winds hit chimneys from the southwest. If your fireplace smokes on windy days or you smell chimney odor after storms, the cap may be the culprit.
Our Chimney Cap & Crown Process - Step by Step
- 1
Schedule and confirm. Call (516) 206-6672 and you’ll reach a live person, not a menu. We book a window that works for you, send a confirmation, and call when the technician is en route. We’ve been doing this long enough to know that showing up when we say matters more than any slogan.
- 2
On-site inspection with photos. Our technician arrives in uniform, inspects your cap, crown, and flue from roof level, and documents everything with photos you’ll see. We use Level-2 camera inspection when the flue interior needs evaluation - documented like an engineer, explained like a craftsman. No guesswork, no pressure.
- 3
Plain-English verdict and upfront pricing. We show you what we found, explain your options, and give you a written estimate with the exact price. The number on the estimate is the number on the invoice. If the crown is sound and only needs coating, we say so. If it’s failed and needs rebuild, we show you why. You decide.
- 4
Professional installation or repair. Most cap and crown work is completed in a single visit. We use professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes. Mounting is secure, sealants are properly cured, and we clean up thoroughly. Russell Haines has always insisted that leaving a job site cleaner than we found it is part of doing the job.
- 5
Documentation and follow-through. You receive photos of the completed work, a written invoice, and our 90-Day Done Right Promise - in writing, no arguing. If something isn’t right, you call and we come back. We’ve honored this promise in Flushing for over 42 years, and we plan to be here for 30 more.
How Much Does Chimney Cap & Crown Cost in Flushing?
Our Chimney Cap & Crown cost guide shows a typical cap replacement in Flushing runs $180-$450 for standard single-flue stainless steel, depending on flue size and mounting complexity. Crown coating for preventive maintenance is usually $350-$600. Crown repair for cracked but structurally sound crowns ranges $400-$900. Full crown rebuilds, when the concrete is too deteriorated to save, typically run $1,200-$1,800. Multi-flue caps start around $350 and increase with span and material. Custom caps in copper or with special dimensions are quoted individually after measurement.
Several factors move the price. Accessibility matters: a steep roof or limited ladder access adds time and safety equipment. The extent of hidden damage - rusted flue liner, deteriorated brick beneath the crown - can extend the scope. And material choice: stainless steel lasts longer than galvanized, and copper outlasts both but costs more upfront. We discuss these tradeoffs plainly so you can choose what fits your situation.
The way to avoid overpaying is simple: get a camera inspection and see the evidence yourself. We don’t recommend work without photos you can examine. Sometimes a crown can be coated when another company wants to rebuild it. Sometimes the opposite is true, and coating would be a waste. Our free estimate includes the inspection, the photos, and a straightforward verdict. No obligation, no pressure.

Frequently Asked Questions - Chimney Cap & Crown in Flushing
The cap is a metal cover that sits over your flue opening to block rain, animals, and debris. The crown is the concrete slab that tops your masonry chimney, sloped to shed water away from the flue walls. You need both because the cap protects the flue interior directly, while the crown protects the chimney structure itself - brick, mortar, and flue liner - from water infiltration. One without the other leaves your chimney vulnerable.
Most standard cap replacements and crown coatings are completed in two to four hours. Crown repairs may take a full day if extensive crack filling and curing time are needed. Full crown rebuilds typically require one day for demolition and forming, plus a return visit after the concrete has cured to seal and finish. We complete most jobs in a single visit, and we tell you upfront if yours will need two.
Standard cap replacement runs $180-$450, crown coating $350-$600, crown repair $400-$900, and full crown rebuild $1,200-$1,800. Custom work and multi-flue caps are quoted after measurement. Your exact price depends on flue size, roof accessibility, material choice, and whether hidden damage extends the scope. Call (516) 206-6672 for a free estimate with photos and a written, no-obligation quote.
Yes. We install, replace, and repair caps from Gelco, Olympia Chimney, Copperfield, and DuraFlex, and we apply HeatShield crown coatings. We stock common Gelco and Olympia Chimney sizes for faster turnaround, and we can source any manufacturer’s product for warranty-matched replacement. If you have a brand not listed here, we can almost certainly help - call to confirm.
A missing or damaged cap should be addressed before the next heavy rain, which in Flushing can happen any season. A cracked crown can wait a few weeks if no water is entering, but not through a full freeze-thaw winter - the damage accelerates rapidly once temperatures drop below freezing. We prioritize urgent cases, and our phones are staffed 24 hours a day, 7 days a week. Call and we’ll tell you honestly whether yours needs immediate attention or can be scheduled at your convenience.
Every cap and crown job is covered by our 90-Day Done Right Promise - in writing, no arguing. If the repair fails, the cap leaks, or anything is not as specified, we return and make it right at no charge. This is backed by our K.E.Y.S. values: Krafted right, Every time, Your home first, Standing behind it. For manufacturer warranties on Gelco, Olympia Chimney, HeatShield, and other brands, we pass through the full factory coverage and handle any claims on your behalf.
Clear a path to your fireplace or stove so we can inspect the firebox and damper. Move any furniture or valuables directly beneath the chimney breast, as dust and small debris can fall during roof work. Ensure we have access to your driveway or a legal parking space - our trucks carry ladders and equipment, and close access saves time. You don’t need to be home for the entire visit if you arrange access, but we prefer to review our findings with you in person. Call (516) 206-6672 to schedule at a time that works.
