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.

Call (845) 757-0998 - a live person answers, 24 hours a day.
We’ve been working on Hicksville chimneys for decades. The hamlet’s post-war housing stock - dense blocks of 1950s Cape Cods and ranches between Jerusalem Avenue and Old Country Road - presents a specific problem most homeowners don’t expect. These chimneys were built to vent oil boilers, not wood fires. That matters because oil-heat exhaust carries sulfur acids that etch clay flue tile and crack concrete crowns from the inside out, while Nassau County’s freeze-thaw cycles finish the job from the outside. Our Chimney Cap & Crown team knows the difference. We dispatch from our New York City office and serve Hicksville properties directly, with background-checked, uniformed techs who complete most jobs in one trip.
Why Hearthstone Chimney Co. Is Hicksville’s Preferred Chimney Cap & Crown Company
We’ve earned our reputation in Hicksville by treating oil-heat flues with the same care most sweeps reserve for wood-burning systems. Homeowners here often assume “no fireplace means no chimney problem” - until a conversion inspector flags a corroded, unlined flue that cannot legally vent a new gas appliance. We’ve heard that story hundreds of times on calls from South Hicksville, from the streets near Cantiague Park, and from the ranch neighborhoods off Wantagh Parkway. Our response time to Hicksville is typically same-week during the pre-season rush of September through November, when smart homeowners schedule before the December oil-heat crunch.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your crown crack is cosmetic and safe to monitor, we’ll say so. If water is washing sulfur soot back down onto your boiler breech and accelerating corrosion, we’ll show you the photo and explain exactly what happens next. The 90-Day Done Right Promise covers every job in writing - if it’s not right, we make it right, no paperwork and no arguing. That’s the Keystone Standard. Krafted right, Every time, Your home first, Standing behind it.

Our Chimney Cap & Crown Services in Hicksville
Crown Repair
Crown repair is the most common call we get from Hicksville’s 1947-1965 housing stock. Original crowns were poured flat with no drip edge, so nor’easter rain sheets directly back against the flue tile. Combine that with decades of sulfur-acid condensate from oil heat, and you’ve got spalled clay liners and mortar joints that look like they’ve been sandblasted. We cut out the failed concrete, form a new crown with proper overhang and drip edge, and slope it so water runs off - not in. A proper crown repair on a typical Hicksville Cape Cod runs $450-$650.
Crown Coating
For crowns with early-stage cracking that hasn’t yet compromised the flue, crown coating buys time and prevents escalation. We use professional-grade flexible sealants formulated for Nassau County’s freeze-thaw abuse - not the hardware-store brush-on products that crack by February. Crown coating in Hicksville typically costs $180-$320 depending on crown size and accessibility. It’s an honest option when the damage is caught early, and we’ll show you the camera footage so you can decide with real information.
Multi-Flue Cap Installation
Most Hicksville chimneys vent multiple appliances - an oil boiler and a water heater, or two separate flue tiles for a converted system. A multi-flue cap covers the entire crown footprint with a single stainless hood, protecting all flues from rain and wind while maintaining proper draft clearances. We size and fabricate from Gelco and Olympia Chimney stock, with mesh screening that keeps squirrels and starlings out without restricting exhaust flow. Multi-flue cap installation in Hicksville runs $320-$480 for standard sizes.
Cap Replacement
Single-flue caps get removed or left off during oil-to-gas conversions, or they rust through after years of salt-air exposure from the Long Island Sound corridor. A missing cap is an open invitation - rain washes sulfur deposits into the flue, animals nest in the warm exhaust column, and debris clogs the breech. We replace with stainless or copper caps from Famco, sized precisely to your flue tile. Cap replacement in Hicksville typically runs $180-$340.

Trusted Brands We Service in Hicksville
We stock professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco - no builder-grade substitutes that fail in their third winter. For Hicksville’s oil-heat flues, we specify stainless multi-flue caps and sulfate-resistant crown formulations that stand up to acidic condensate. Our New York City warehouse keeps common Hicksville sizes in stock, so most cap and crown jobs don’t wait on special orders. The brands matter because a cap that rusts out in four years costs more than one that lasts twenty. We don’t install anything we wouldn’t put on our own homes.
Common Chimney Cap & Crown Problems We See in Hicksville Homes
- Flat original crowns with zero drip edge. Builders in Hicksville’s post-war rush poured crowns level with the brick course - functional for 1954, catastrophic by 2024. Rain sheets back against the flue tile, freeze-thaw spalls the face, and sulfur acids finish the liner from inside. We replace with sloped, overhung crowns that shed water like a roof.
- Sulfur-acid crown cracking read as “cosmetic.” Homeowners see a hairline on the crown and assume it’s aging concrete. It’s actually acid etching that opens channels for freeze-thaw water, which expands, deepens the crack, and eventually delaminates the crown in sheets. Early crown coating stops this. Waiting means full rebuild.
- Missing caps after conversion work. When Hicksville homeowners switch from oil to gas or install heat pumps, the HVAC contractor sometimes removes the old cap and never replaces it - or installs a cap sized for the new appliance that leaves the second flue tile open. Both scenarios fail Level-2 inspection instantly and expose the flue to water and pests.
- Animal intrusion in uncapped flues. Squirrels, starlings, and the occasional raccoon treat an open flue as ready housing. We’ve pulled nests from Hicksville chimneys that completely blocked the boiler exhaust - a carbon monoxide risk that has nothing to do with creosote and everything to do with a missing $200 cap.

FAQs - Chimney Cap & Crown in Hicksville
Yes. An uncapped oil-heat flue lets rain wash sulfur soot back down onto your boiler breech, accelerates liner corrosion, and invites animals that can block exhaust and create carbon monoxide risk. Most of our Hicksville cap calls come from homeowners who assumed “no fireplace, no problem” until a conversion inspector or camera inspection proved otherwise. Call (845) 757-0998 for a free estimate - we’ll show you exactly what your flue looks like from the top.
A failing crown shows visible cracking, spalling concrete, or pooling water on its surface - not just soot staining. The critical test is whether water is getting past the crown into the flue system, which our Level-2 camera inspection reveals in minutes. In Hicksville’s oil-heat chimneys, we often find crown cracks that look minor from the ground but have already allowed sulfur-acid condensate to saturate the flue liner. Photos don’t lie. We’ll give you the camera evidence and a plain verdict: monitor, coat, or rebuild.
Crown coating is a preventive treatment for early-stage cracking - we clean the crown, fill hairlines, and apply a flexible, sulfate-resistant sealant that flexes with freeze-thaw cycles. Full crown repair means the concrete is too far gone: we cut out the failed material, rebuild the form, and pour new concrete with proper slope, overhang, and drip edge. Coating costs $180-$320 in Hicksville; repair runs $450-$650. We never recommend coating a crown that needs rebuilding - the camera photos let you see why.
Yes, and in Hicksville this is one of the smartest pre-conversion moves you can make. A sound crown and proper cap protect the flue liner while you plan conversion, and they preserve the chimney’s integrity if you’re keeping a secondary appliance. On a 1954 Cape Cod off Jerusalem Avenue, we found the original clay flue tile spalled and a crown with a hairline crack running to the edge - no wood fire had ever been burned in the firebox. Our techs cut out the failed crown, poured a new overhang crown with a drip edge, and set a stainless multi-flue cap over the two tile liners so wind-driven rain off the nor’easter track couldn’t wash sulfur soot back down onto the boiler breech. Six weeks later the homeowner’s oil-to-gas conversion inspector signed off without a reline. Capping and crowning doesn’t guarantee you’ll avoid reline costs, but it eliminates the most common reason conversion inspectors fail chimneys: water-damaged, unprotected flues. Call (845) 757-0998 to assess your chimney before you schedule conversion work.
Yes - the cap must match the appliance’s exhaust characteristics. Oil boiler flues need caps that handle higher moisture content and corrosive sulfur compounds without rusting; we specify stainless steel from Gelco or Olympia Chimney for Hicksville oil systems. Wood stove flues need caps with proper spark arrestor mesh and draft-friendly design, typically from Famco’s wood-burning line. Sizing also differs: oil boiler flues in Hicksville’s 1950s homes usually vent through 8×8 or 8×12 clay tile, while wood stove inserts often require smaller, adapter-mounted caps. We measure and specify correctly so you don’t get a cap that fits but fails functionally. Call (845) 757-0998 and we’ll sort out exactly what your flue needs.
