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.

Our crews know the postwar Capes and ranches off Nassau Road, the original masonry flues built for oil burners that now serve gas furnaces, and the way South Shore salt air eats metal faster than it should. Dispatch and scheduling are coordinated from our New York City office, but our technicians live and work locally, and they carry the parts and materials to fix most cap and crown problems without a return trip.
Why Hearthstone Chimney Co. Is Roosevelt’s Preferred Chimney Cap & Crown Company
Our reputation in Roosevelt was built one chimney at a time. Homeowners here talk to their neighbors.

That’s why our Chimney Cap & Crown team is still getting calls from families whose parents first hired us in the 1980s.
We answer the phone with a live person, 24 hours a day, 7 days a week. Not a voicemail. Not a callback queue. When you call (631) 735-5125, someone picks up. Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict you can understand. Most cap and crown jobs in Roosevelt are completed in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
We know Roosevelt’s housing stock because we’ve been inside hundreds of these homes. The 1953 ranch off Nassau Road with the wood stove for primary heat. The Cape Cod near the Southern State with the shared flue that nobody realized was backdrafting. The brick faces spalled by salt air, the mortar joints opened by freeze-thaw, the crowns cracked because they were never meant to handle what Long Island winters throw at them. This is not generic knowledge. It is the accumulated experience of decades working on the exact chimneys you have.
Every job is backed by our 90-Day Done Right Promise, in writing, with no arguing. If it is not right, we come back. Krafted right, Every time, Your home first, Standing behind it. That is the Keystone Standard, and it has governed our work since 1984.
Our Chimney Cap & Crown Services in Roosevelt
Cap Replacement
Roosevelt’s salt-laden Atlantic air destroys cap screens and rusts out galvanized hardware faster than inland communities just 20 miles north. We replace failed caps with professional-grade stainless models from Gelco and Famco, sized precisely for your flue. A proper cap stops rain from pouring into an already compromised flue, keeps animals out, and reduces the wind-driven downdrafts that plague South Shore chimneys. Most replacements take under an hour.

Crown Repair & Coating
The crown is the concrete slab that seals the top of your chimney between the flue tiles and the brick edge. In Roosevelt, Long Island’s hard freeze-thaw cycles exploit every hairline crack, and salt air accelerates the deterioration. We patch structural cracks and apply Crown Coat, a professional-grade flexible coating that seals the surface and prevents water from reaching the interior masonry. For severely deteriorated crowns, we may recommend a full rebuild. We’ll show you photos and explain exactly what you’re looking at before you decide.

Custom Cap Installation
Roosevelt’s postwar Capes and ranches often have unusual flue configurations, especially where a single chimney serves both a heating system and a fireplace. Off-the-shelf caps do not fit properly. We fabricate and install custom multi-flue caps from Copperfield and Olympia Chimney, measured to your exact chimney top. A custom cap is not a luxury add-on on these chimneys. It is the difference between a sealed system and one that lets rain and wind into a flue that is already struggling to vent properly.

Multi-Flue Cap Solutions
The classic Roosevelt setup, a single chimney with two flues sharing the same crown, demands a cap that covers both without blocking draft or creating clearance issues. Our multi-flue caps are engineered for proper ventilation and spark protection, with screened sides that keep debris out while letting exhaust escape. We measure on site and fabricate to fit.

Trusted Brands We Service in Roosevelt
We stock professional-grade materials from Olympia Chimney, Famco, and Copperfield, no builder-grade substitutes. These are the brands that professional sweeps specify when they want a cap to last through Long Island’s coastal conditions.

For custom fabrications, turnaround is typically a few days, and we coordinate installation at your convenience.
Common Chimney Cap & Crown Problems We See in Roosevelt Homes
- Oversized flues condensing and cracking after oil-to-gas conversions. Roosevelt’s postwar Capes and ranches sit on original masonry chimneys that were sized for oil burners, so after decades of oil-to-gas conversions the flues are drastically oversized. Flue gases cool and condense inside aging clay tile liners instead of exhausting, which is why we see far more cracked-and-offset liner joints here than in newer South Shore builds. A properly sized cap slows this damage by keeping rain out and improving draft.
- Salt air spalling brick and eroding mortar. Roosevelt’s South Shore Nassau County position means salt-laden Atlantic air contributes to accelerated spalling of chimney brick faces and rapid erosion of mortar joints on exposed exteriors. Long Island’s hard freeze-thaw cycles each winter then exploit any existing crack or soft mortar joint, making exterior chimney deterioration faster here than in inland communities just 20 miles north. The crown takes the worst of it.
- Shared flues creating backdraft hazards. A pattern local techs see repeatedly in Roosevelt: a single chimney flue shared between a gas furnace and a wood-burning fireplace with no stainless liner ever installed after the oil-to-gas switchover. This setup violates current Nassau County and NYS code and creates real backdrafting and carbon monoxide risk. It often gets discovered only during a routine cleaning visit. A proper cap and crown inspection is part of catching these dangerous configurations.
- Wood stoves loading creosote and masking crown damage. Wood stoves run as primary heat in these unrenovated homes load second- and third-degree creosote fast. At a 1953 ranch off Nassau Road in Roosevelt, our tech pulled a heavily loaded flue on a wood stove that had become the family’s primary heat source and found the crown ring cracked in three places and the cap screen completely eaten by salt air. The first-degree creosote brushed out clean, so we installed a Gelco stainless cap, patched and coated the crown with Crown Coat, and left the homeowner a burning-practice card, split, seasoned wood, small hot fires, to stretch the next sweep interval out a full season.

FAQs - Chimney Cap & Crown in Roosevelt
Yes, and urgently. That shared-flue configuration violates current Nassau County and New York State code, and a missing or failed cap lets rain pour directly into a flue that is already cooling and condensing because it is oversized for your gas appliance. We see this exact setup constantly in Roosevelt’s postwar ranches. The cap is your first defense. The crown is your second. But the real issue is the shared flue itself, and we will show you camera evidence of what is happening inside so you can decide on next steps with full information. Call (631) 735-5125 for a free Level 2 inspection.
It is usually both, or the crown failing underneath a cap that is no longer seated properly. The crown is the concrete slab; the cap sits on top of or around the flue. In Roosevelt, salt air attacks the brick and mortar, then freeze-thaw opens cracks in the crown that a cap alone cannot cover. We photograph the top from a ladder or roof level and show you exactly which layer is damaged. Crown coating can rescue a cracked but structurally sound crown. A full rebuild is needed when the concrete has spalled down to the reinforcing mesh. Call (631) 735-5125 and we’ll sort out which you have.
If you are burning six or more cords per winter as primary heat, schedule a Level 2 inspection and sweep every year, ideally in late summer before burning season starts. Roosevelt’s older Capes and ranches often have chimneys that were never designed for the concentrated flue-gas temperatures of a modern wood stove, and the combination of heavy use plus an oversized flue means creosote condenses in places a brush cannot reach without camera guidance. We will inspect with a camera, remove what we can, and leave you with specific burning-practice guidance, split, seasoned hardwood, small hot fires, to keep buildup manageable. Call (631) 735-5125 to schedule before the fall rush.
Yes, measurably. Roosevelt’s position on Long Island’s South Shore exposes chimneys to Atlantic air that inland communities 20 miles north simply do not get. We replace cap screens in Roosevelt that have corroded through in five to seven years, while similar hardware in Hicksville or Plainview lasts twelve to fifteen. The salt accelerates spalling on brick faces and erodes mortar joints, which then lets water behind the crown. A stainless cap and a properly coated crown are not optional maintenance here. They are the minimum to keep a masonry chimney intact through a Long Island decade. Call (631) 735-5125 for a condition assessment.
Yes, and it is often the right solution for Roosevelt’s Capes with two flues emerging from the same chimney top. We measure the spacing, draft requirements, and clearances on site, then fabricate a multi-flue cap from Copperfield or Olympia Chimney that covers both flues with proper ventilation and spark protection. The alternative, two separate caps on a deteriorating crown, usually leaks between them within a season or two. A custom single-piece cap seals the entire chimney top and gives you one coherent defense against South Shore weather. Call (631) 735-5125 for a measured estimate.
