We know the chimneys on Bellmore Avenue, Jerusalem Avenue, and the side streets off Newbridge Road. These are not new builds. They are 1950s and 1960s split-levels and ranches, and their chimneys show it in specific, predictable ways. Our Chimney Repair crews have worked through enough nor’easters and coastal winters here to know what fails first and what can safely wait.
Why Flint Chimney Co Hempstead Is North Bellmore’s Preferred Chimney Repair Company
North Bellmore homeowners do not want a sales pitch. They want someone who shows up on time, names a price in writing, and stands behind the work. That is how we have operated since 2002, under the same code every Garrison Partners location follows. The Garrison Standard means a written price before we touch anything, a uniformed and background-checked technician on every call, and a 365-Day Done Right Promise in writing on every repair.
We also answer the phone. Not a call center. A live person, any hour, any day. When a chimney cap blows off during a February nor’easter, you reach a human being who can schedule a North Bellmore visit, not a voicemail tree.
Hank Delano has built our reputation on one habit: never recommend work you cannot show the homeowner. If we tell you a flue liner is cracked, we show you the camera footage. If a damper is seized from salt corrosion, you see it before you approve a replacement. That is the only way to run a chimney company in North Bellmore, where half the homes are old enough that somebody has already tried to sell their previous owners a repair they did not need.
Styles & brands we work with





Chimney Cap Installation in North Bellmore
Chimney Cap Installation in North Bellmore is the most common request we get after a homeowner sees rust staining on their chimney crown or finds a dead bird in the firebox. A chimney cap is the metal cover that sits on top of the flue. It keeps rain, snow, leaves, birds, and squirrels out while still letting smoke and gases escape. In North Bellmore, where salt-laden air from the South Shore marshes travels less than two miles inland, caps rust faster than they do in central Nassau. A standard galvanized cap may last eight years here. Stainless steel lasts considerably longer.
A new chimney cap installation in North Bellmore typically runs $225 – $450, including the cap, fastening hardware, and labor. The price depends on flue size and whether the old cap left behind damaged mortar at the crown that needs a quick patch.
Why a Cap Matters More Than You Think
An uncapped flue in North Bellmore takes on water every time it rains. That water soaks into the masonry, and when temperatures drop below freezing, it expands. After a few dozen freeze-thaw cycles, the mortar joints start to crumble. A $300 cap installed now prevents a $1,200 repointing job in two years. We specify Copperfield and Olympia Chimney caps for North Bellmore jobs because they hold up better in coastal air than big-box galvanized models.
What We Check Before Installing
We do not just drop a cap on and leave. We check the flue tile condition at the top, clear any debris, and make sure the crown is sound enough to anchor the cap properly. If the crown is cracked, we tell you and give you a written price for the patch before doing it. No surprise add-ons.
Chimney Cap Replacement in North Bellmore
Chimney Cap Replacement in North Bellmore usually happens when an older cap has rusted through or blown off during one of the coastal storms that roll across the south shore of Nassau County. A replacement follows the same steps as a new installation: remove the old cap, clean the flue opening, and secure a new cap rated for the flue size. Replacement in North Bellmore typically runs $200 – $400 depending on whether we can reuse the existing mounting hardware.
If the old cap came off because the mortar around it was already failing, we will say so. Replacing a cap without addressing the crown is a waste of your money. We would rather tell you that up front and give you one written price for both the crown patch and the new cap than come back in a year to redo the work.
Salt Corrosion and Damper Trouble
One pattern we see in North Bellmore more than in inland towns: cast-iron dampers rusted solid from years of salt exposure. The damper is the metal plate just above the firebox that opens and closes the flue. When it seizes, the fireplace does not draft properly, and smoke rolls back into the room. We replace seized dampers with salt-resistant models and recommend caps with stainless hardware to slow the same corrosion from spreading upward.
Brands We Trust for Cap Replacement
For most North Bellmore cap replacements, we install Olympia Chimney or Famco stainless steel caps. They hold up better in coastal air than galvanized steel and carry solid manufacturer warranties. We stock common flue sizes locally, so we can usually complete a cap replacement in a single visit without ordering parts and waiting.
Trusted Brands We Service in North Bellmore
We work with professional-grade chimney materials from manufacturers that stand behind their products. DuraFlex liners, HeatShield resurfacing products, Olympia Chimney caps, and Famco components are the ones we specify for North Bellmore jobs because they have proven themselves in coastal Long Island conditions. We stock common replacement parts for these brands locally, which means less waiting and fewer follow-up visits. When a North Bellmore homeowner calls about a corroded cap or a cracked flue tile, we can usually have the right material on the truck the first time. That is the operational discipline our customers are paying for.

AfterCommon Chimney Repair Problems We See in North Bellmore Homes
- Cracked terra cotta flue liners. North Bellmore’s mid-century homes still have their original clay liners, and after 60 years of freeze-thaw cycles, those liners crack along the mortar joints. The cracks trap creosote in hidden voids where a brush cannot reach, and that is where chimney fires start.
- Rusted cast-iron dampers from salt air. The South Shore marshes sit just south of North Bellmore, and the salt in the air corrodes dampers and cap hardware faster than in Hempstead or Flushing. We see seized dampers on homes that are otherwise in good shape.
- Spalling brick from water absorption. When chimney brick soaks up rain and then freezes, the brick face pops off in sheets. Spalling is common on North Bellmore chimneys that were never waterproofed, especially on the north-facing sides that stay damp longer.
- Creosote buildup from wood stoves used as primary heat. Some North Bellmore homes, particularly the older ranches, rely on wood stoves for serious heat, not just ambiance. That means faster creosote loading and a shorter safe cleaning interval. A stove burning daily in North Bellmore’s damp climate can load enough creosote to require cleaning every 30 to 60 days at peak season.

FAQs About Chimney Repair in North Bellmore
Because the original terra cotta flue liners in those chimneys are now 55 to 70 years old, and Long Island’s freeze-thaw cycles have cracked many of them. A basic brushing removes surface creosote but does not reveal what is behind a cracked tile. Our Level 2 inspection in North Bellmore includes a camera scan of the flue so we can see voids and glaze deposits before they become a chimney fire. Call (516) 559-6922 to schedule an inspection before burning season.
Salt-laden air accelerates rust on cast-iron dampers and galvanized steel caps. In North Bellmore, we routinely find dampers seized solid and caps rusted through in half the time they last in inland Nassau towns. We recommend stainless steel caps and salt-resistant damper models for homes in North Bellmore. The difference in material cost is modest, and the service life is much longer.
If you are burning daily as a primary heat source, every 30 to 60 days during peak season is the honest interval. North Bellmore’s damp climate makes wood burn cooler and produce more creosote than the same stove would in a dry climate. Waiting a full year between cleanings allows first-degree creosote to harden into third-degree tar glaze, which brushes cannot remove and which burns hot enough to crack flue liners. Call (516) 559-6922 and we will set a cleaning schedule based on how you actually burn.
In most cases, yes. HeatShield resurfacing can restore a cracked clay liner by applying a new ceramic coating to the inside of the flue, sealing cracks and filling voids. This is far less invasive than a full liner replacement. If the damage is too extensive, we will tell you that too, and show you the camera footage. We never recommend rebuilding a chimney in North Bellmore without giving you a written explanation of why it is necessary.
Burn seasoned hardwood that has dried for at least six to twelve months. Wet or green wood smolders at lower temperatures and produces far more creosote. Burn hot fires rather than long, smoldering ones, and make sure your stove gets enough air. Even with good burning practice, North Bellmore’s damp air means you will still need cleaning more often than a homeowner in a drier climate. Call (516) 559-6922 for an honest cleaning interval based on your stove and wood supply.
