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.

Why Smithtown Homeowners Choose Hearthstone Chimney Co.
Smithtown homeowners tend to stay put. The ranch on Timberpoint Road, the Cape Cod near the Nissequogue River, the split-level off Jericho Turnpike - these are homes people raised families in, paid off, and settled into for the long haul. That kind of ownership changes how you think about maintenance. You don’t want the cheapest fix. You want the fix you won’t have to think about again.
That’s the customer we built this company for.
Russell Haines has led Hearthstone Chimney Co. since the early days, and our K.E.Y.S. code hasn’t changed: Krafted right, Every time, Your home first, Standing behind it. The 90-Day Done Right Promise backs every job in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing about what was promised.
Our technicians are background-checked, uniformed, and trained to complete most jobs in a single visit. They carry professional-grade materials from Olympia Chimney, Famco, and DuraFlex - never builder-grade substitutes that fail in five years. Every Level-2 camera inspection ends with photos you can see yourself and a plain-English verdict. Documented like an engineer, explained like a craftsman.
We’ve worked the chimneys on Old Post Road, the homes near the Smithtown Bull, the neighborhoods branching off Route 25A. We know which blocks were built in 1958 with original clay flue tiles still in service, and which village-center homes near the Nissequogue date back far enough to have rubble-stone chimneys with no formal liner at all. That local knowledge matters when we’re diagnosing what your chimney actually needs versus what a quick glance might suggest.
Chimney Cleaning Services We Offer in Smithtown
Chimney Cleaning & Sweep
Our standard sweep removes creosote buildup, bird nests, and debris from the flue using professional brushes and HEPA-containment vacuums. We finish with a Level-1 visual inspection of accessible components to catch deterioration before it becomes a hazard. Learn more about our Chimney Cleaning & Sweep in Smithtown.
Chimney Repair
We rebuild deteriorated crowns, repoint spalling mortar, and replace damaged brickwork using materials rated for Smithtown’s salt-air exposure. Every repair proposal includes photos of the damage and a fixed-price estimate with no surprises on the bill. Learn more about our Chimney Repair in Smithtown.
Fireplace Services
From damper adjustment and smoke-chamber parging to firebox refractory panel replacement, we restore safe, efficient fireplace function. Our technicians inspect the full system, not just the visible hearth, because draft problems often start fifteen feet up the flue. Learn more about our Fireplace Services in Smithtown.
Chimney Cap & Crown Installation
A proper cap keeps rain, animals, and wind-driven debris out of your flue, while a sound crown sheds water away from the masonry below. We fabricate and install caps from Copperfield and Gelco materials, with sizing and fastening appropriate to your chimney’s dimensions and exposure.
Chimney Liner & Rebuild
This is where Smithtown’s housing history becomes critical. The postwar suburban boom across Kings Park, Nesconset, and St. James produced thousands of homes whose chimneys were sized and lined for #2 fuel-oil burners. When homeowners converted to natural gas over the past two decades, most of these chimneys were never relined. The result: oversized clay-tile flues that cause gas appliance exhaust to condense inside, silently corroding mortar joints and creating carbon monoxide risk. We install DuraFlex stainless steel liners and HeatShield cerfractory flue sealant systems, sized precisely to your appliance’s output and documented with before-and-after camera footage.
Neighborhoods We Serve in Smithtown
Our crews work the full Smithtown township, with same-day and next-day availability through most of the sweep season. These are the neighborhoods we know best:
- Kings Park - postwar ranches with original oil-flue chimneys now serving gas appliances
- Nesconset - split-levels and Capes from the 1960s-1970s with single-wythe brick chimneys showing their age
- St. James - mixed-era housing from village-center colonials to mid-century subdivisions
- Smithtown village center - historic homes along the Nissequogue River with rubble-stone or early brick construction
Whether you’re off Jericho Turnpike or near the Bull at the intersection of Main Street and Route 25, we know the local building stock and the specific problems it develops.
Why Smithtown’s Climate & Housing Affect Chimney Cleaning
Smithtown sits close enough to Long Island Sound that salt-laden air accelerates spalling and mortar erosion on exterior chimney masonry faster than inland suburbs experience. The Nissequogue River running through town adds localized humidity that worsens interior flue condensation during shoulder seasons, when oil or gas heat cycles intermittently and never fully dries the flue.
The dominant housing stock - 1950s through 1970s single-story ranch and Cape Cod homes built during Long Island’s postwar suburban expansion - compounds the problem. Most have single-wythe brick chimneys with original segmented clay flue tiles now 50 to 70 years old. In Kings Park and Nesconset, we regularly find original oil-flue chimneys where a homeowner installed a high-efficiency gas furnace and vented it through the old clay-tile stack with no liner insert. The cooler, wetter exhaust eats through decades of oil-soot deposits and deteriorates the mortar from the inside out. There are zero visible exterior warning signs until the flue collapses or carbon monoxide enters the living space.
This is why we recommend Level-2 camera inspection for any Smithtown home that has converted from oil to gas, or any home with a chimney over forty years old. The photos don’t lie, and the verdict is in plain English - not a sales pitch.

FAQs About Chimney Cleaning in Smithtown
A standard chimney sweep and Level-1 inspection in Smithtown costs between $189 and $289, depending on accessibility and the amount of creosote buildup. Level-2 camera inspections with photo documentation run $249 to $379. We quote the exact price before booking, and that’s the price on the invoice. Call (631) 814-2057 for a free estimate.
The National Fire Protection Association recommends annual inspection for all chimneys, with sweeping as needed based on use and fuel type. In Smithtown’s humid, salt-air climate, we see accelerated mortar deterioration and flue condensation, so annual inspection is especially important for homes with gas conversions in original oil-flue chimneys. If you burn wood regularly, plan on sweeping every cord of wood or at minimum once per season. Call (631) 814-2057 to schedule.
Not always. A properly sized, intact clay flue tile in good condition may be adequate for some applications. But in Smithtown’s postwar housing stock, we frequently find oversized flues from original oil-burner installations now venting gas appliances. The cooler exhaust condenses, corrodes mortar, and creates carbon monoxide risk. We never recommend relining without camera evidence you can see for yourself, and we’ll tell you plainly when work can safely wait. Call (631) 814-2057 for an inspection and honest verdict.
creosote buildup increases fire risk. Blocked or deteriorated flues can backdraft carbon monoxide into living spaces. In Smithtown specifically, the combination of salt-air masonry erosion and humid flue condensation means problems develop faster than in drier inland climates. The cost of prevention is modest; the cost of a chimney fire, CO poisoning, or major rebuild is not. Call (631) 814-2057 to book before burning season.
We don’t recommend it. Proper chimney cleaning requires the right brushes, rods, and HEPA vacuum containment for the mess. More importantly, the critical work is the inspection that follows - identifying cracked flue tiles, deteriorated mortar, or improper clearances that a homeowner lacks the training and camera equipment to assess. For safety and thorough documentation, hire a professional. Call (631) 814-2057 and we’ll handle it.

What Smithtown Customers Say
"The crown was cracked and taking water. He repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
- Rashad Jackson"Drop cloths everywhere, a HEPA vac running the whole time, and not a speck of soot on the carpet. I had been dreading the mess for nothing."
- Danielle Norris"The liner was cracked in two places. He walked me through the options honestly, including the one that was cheaper for him and better for me."
