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.
Chimney Cleaning in Smithtown, NY
Chimney cleaning in Smithtown, NY typically costs $189 to $379 for a standard sweep with a Level 1 inspection, and most jobs are completed in about two hours. What makes Smithtown work different is the housing stock: thousands of Cape Cods, Ranches, and Colonials built between 1950 and 1975, each carrying an original masonry chimney with clay tile liners now 50 to 70 years old. Combine that age with the salt-laden air blowing off Long Island Sound, and you get mortar joints eroding faster than they would in towns just a few miles inland. If you want a camera-scan inspection included as standard on every visit, call (980) 580-8641 for a written price before any work starts.
Why Smithtown Homes Are Different
Smithtown’s post-WWII suburban boom concentrated between the 1950s and 1970s produced thousands of nearly identical Cape Cod, Ranch, and Colonial homes. The builders of that era used the same materials and methods across entire subdivisions: masonry chimneys with clay tile flue liners, brick crowns, and mortar mixed on site. Those liners have a typical service life of about 50 years, which means most Smithtown chimneys are now running on borrowed time.
The North Shore position makes it worse. Persistent salt-laden coastal moisture from Long Island Sound accelerates mortar joint erosion and spalling at a rate you simply don’t see in Hauppauge or other inland Suffolk County towns. Regular nor’easters drive wet snow against chimney stacks, and every freeze-thaw cycle through the winter works the cracks wider. In hamlets like Kings Park and Nesconset, we routinely find 1960s and 70s Colonials where the original flue was sized for an oil burner, then left unlined or with a cracked liner after the homeowner switched to gas. The fireplace still gets used for wood burning on the assumption that the chimney is fine. It often isn’t. The oversized flue produces chronic condensation that deteriorates liner joints from the inside, while the salt air attacks the exterior masonry from the outside. That’s the Smithtown pattern, and it’s why a camera-scan inspection matters more here than almost anywhere else on the Island.
Our Main Smithtown Services
Beyond the cleaning and repair work detailed below, Smithtown homeowners call us most about two specific services, each with its own dedicated page for this area.
Fireplace Services in Smithtown
A wood-burning fireplace in a 1960s Colonial with an oversized gas-converted flue needs more than a casual glance. Our Fireplace Services in Smithtown cover everything from damper replacement to smoke chamber parging, and every visit includes a camera run down the flue so you can see exactly what’s happening inside the masonry you can’t reach. We see a lot of fireplaces in Smithtown that were built for oil heat and never properly resized, which changes how the draft behaves and how much creosote accumulates.

Chimney Cap & Crown in Smithtown
The crown is the flat concrete or mortar slab at the top of your chimney, and in Smithtown it takes the full force of every nor’easter and salt-laden wind off the Sound. A cracked crown lets water into the brick, and in a freeze-thaw climate that’s how small cracks become spalled brick and structural damage. Our Chimney Cap & Crown in Smithtown page covers installation, repair, and replacement with written pricing before any work begins.

Before
AfterChimney Sweep in Smithtown

Chimney cleaning in Smithtown is the first line of defense for homes built in the 1950s through 1970s suburban expansion. The original clay tile liners in these chimneys are now well beyond their typical 50-year service life, and the salt air off the Sound erodes the exterior mortar while the interior accumulates creosote from regular wood burning. A standard Chimney Sweep with a camera-scan inspection meets the NFPA 211 Level 2 standard, and it’s the only way to know whether your flue is simply dirty or quietly failing.
Level 1 Inspection
Signs you need it
You burn wood regularly and haven’t had the chimney looked at in the past 12 months.
What it costs in Smithtown
A Level 1 inspection typically ranges from $99 to $249 in Smithtown when bundled with a sweep.
How we do it
We check the accessible portions of the fireplace, flue, and exterior, then document everything with photos you keep.
Level 2 Inspection
Signs you need it
You’ve changed fuel types, had a chimney fire, or bought a home where the chimney history is unknown.
What it costs in Smithtown
A Level 2 inspection with camera scanning typically ranges from $249 to $449 in Smithtown.
How we do it
We run a camera down the full flue length, inspect the attic and crawlspace penetrations, and give you a written report with images.
Creosote Removal
Signs you need it
You see a dark, tar-like buildup on the fireplace walls or you smell smoke even when the damper is closed.
What it costs in Smithtown
Creosote removal as part of a sweep typically runs $189 to $379 in Smithtown, with heavy Class III glaze adding $100 to $200.
How we do it
We use rotary brushes and hand tools matched to the creosote class, then camera-verify that the flue walls are clean.
Soot Removal
Signs you need it
Black powder falls into the firebox when you open or close the damper, or you notice poor draft on startup.
What it costs in Smithtown
Soot removal as part of a standard sweep falls between $189 and $299 for most Smithtown chimneys.
How we do it
We brush the full flue from the top down or bottom up depending on access, then vacuum the firebox and smoke chamber.
Annual Sweep
Signs you need it
It’s been more than a year since the last cleaning and you burn wood at least once a week during the season.
What it costs in Smithtown
An annual sweep with a Level 1 inspection typically runs $189 to $299 in Smithtown, with larger or multi-flue chimneys at $300 to $379.
How we do it
We sweep the flue, clean the smoke chamber and firebox, check the damper operation, and walk you through the photo record before we leave.
What Chimney Sweep Costs in Smithtown

| Sweep with Level 2 camera-scan inspection | $249 - $449 |
| Heavy Class III creosote removal | $289 - $579 |
How often should a chimney be swept in Smithtown?
Every 12 months if you burn wood regularly. The salt air here doesn’t change that schedule, but the age of Smithtown’s clay tile liners means the annual camera check matters more than the brushing itself.
Can you clean my chimney the same week I call?
Most Smithtown sweeps can be scheduled within 3 to 5 business days. Call (980) 580-8641 and we’ll give you a written quote before you commit to a date.
Chimney Repair in Smithtown

Chimney repair in Smithtown is usually about water. The North Shore’s salt-laden moisture works into the mortar joints of 1950s and 60s brick chimneys, and every freeze-thaw cycle widens the cracks until spalling starts and the structure weakens. A Chimney Repair quote from us always starts with a camera-scan inspection so you can see the damage before anyone asks you to spend money on it.
Mortar Repointing
Signs you need it
You can scrape crumbling mortar out of the joints with a screwdriver, or you see daylight through the joints from the attic.
What it costs in Smithtown
Repointing typically runs $25 to $45 per square foot of masonry in Smithtown, depending on joint depth and access.
How we do it
We grind out the failed mortar to a consistent depth, pack in new mortar matched to the original color, and tool the joints to shed water.
Spalling Brick Repair
Signs you need it
Brick faces are flaking off, leaving smooth or pitted surfaces, and you find brick chips on the ground near the chimney.
What it costs in Smithtown
Spalling brick repair in Smithtown typically costs $40 to $75 per square foot, with individual brick replacement at $15 to $35 per brick.
How we do it
We cut out the damaged brick, set in matching replacements with Type N mortar, and seal the surrounding area against further water intrusion.
Chimney Waterproofing
Signs you need it
Water stains are visible on interior walls near the chimney, or the brick looks darker and wet after rain.
What it costs in Smithtown
Chimney waterproofing runs $250 to $550 for a typical Smithtown chimney, depending on height and surface area.
How we do it
We clean the masonry, repair any failed joints first, then apply a vapor-permeable water repellent that lets the brick breathe while blocking moisture.
Flashing Repair
Signs you need it
You see rusted or lifted metal where the chimney meets the roof line, or you have a leak that only appears after heavy rain.
What it costs in Smithtown
Flashing repair typically ranges from $400 to $1,500 in Smithtown depending on the number of planes and whether the roof is steep.
How we do it
We replace the step and counter flashing, seal the overlaps with roofing-grade sealant, and document the final result with photos.
What Chimney Repair Costs in Smithtown
| Item | Typical range in Smithtown |
|---|---|
| Repointing (per sq ft) | $25 - $45 |
| Spalling brick repair (per sq ft) | $40 - $75 |
| Flashing repair | $400 - $1,500 |
Do I need repointing or a full rebuild?
If the bricks themselves are intact and only the joints are failing, repointing is usually enough. If the brick faces are spalling and the structure has shifted, a rebuild may be the honest answer. We’ll show you the camera footage either way.
Can salt air really damage a chimney that fast?
Yes. Smithtown’s coastal moisture carries salt that wicks into the mortar and accelerates erosion, especially on the north-facing planes that take the worst of the Sound’s weather. Annual inspection catches it early.
Chimney Liner & Rebuild in Smithtown

Chimney liner and rebuild work in Smithtown is the end stage of a story that started when the house was built. A 1960s clay tile flue that was oversized for an oil burner, then left in place after a gas conversion, has spent years condensing acidic exhaust inside the liner while salt air ate the exterior mortar. A Chimney Liner & Rebuild quote from us includes a camera scan of the full flue length and a written recommendation that tells you plainly whether a liner replacement or a partial rebuild is actually required.
Stainless Steel Liner
Signs you need it
Your clay tiles are cracked, spalled, or missing, but the surrounding masonry is still structurally sound.
What it costs in Smithtown
A stainless steel liner installation typically runs $1,800 to $3,500 in Smithtown for a standard single-flue chimney.
How we do it
We size the liner to the appliance and flue, drop it in from the top, insulate it, and reconnect the appliance with a written warranty.
Flexible Liner
Signs you need it
Your flue has an offset or bend that a rigid liner can’t navigate without tearing out masonry.
What it costs in Smithtown
Flexible liner systems run $1,800 to $3,500 in Smithtown, similar to rigid stainless, depending on flue length and insulation needs.
How we do it
We measure the offset from the camera footage, select the appropriate alloy, and pull the liner through the existing flue path.
Liner Replacement
Signs you need it
The camera scan shows sections of missing tile or gaps between tile joints, and the flue is no longer a continuous barrier.
What it costs in Smithtown
Liner replacement in Smithtown ranges from $1,800 to $4,500, with HeatShield or stainless options depending on the flue condition.
How we do it
We remove the failed liner sections where necessary and install a code-compliant replacement, then camera-verify the full run.
Partial Rebuild
Signs you need it
The top courses of brick are spalled and loose, but the chimney below the roofline is solid.
What it costs in Smithtown
A partial rebuild from the roofline up typically runs $2,500 to $5,000 in Smithtown for a standard chimney.
How we do it
We remove the failed bricks, rebuild the stack with matching materials, install a new crown and cap, and document the whole process.
Full Chimney Rebuild
Signs you need it
The entire chimney leans, bricks are falling, or the structure has failed below the roofline.
What it costs in Smithtown
A full chimney rebuild in Smithtown starts around $7,500 and can exceed $20,000 depending on height, access, and footing condition.
How we do it
We dismantle the existing chimney, pour a new footing if required, and rebuild the full stack to current code with a new liner system.
What Chimney Liner & Rebuild Costs in Smithtown
| Item | Typical range in Smithtown |
|---|---|
| Stainless steel or flexible liner | $1,800 - $3,500 |
| HeatShield liner repair | $1,800 - $4,500 |
| Partial rebuild above roofline | $2,500 - $5,000 |
Do I really need a new liner, or can it be repaired?
A camera scan gives you the answer. If the tiles are cracked but the flue itself is still intact, a HeatShield resurfacing job can buy you years. If sections of tile are missing, a replacement liner is the code-compliant fix. Call (980) 580-8641 and we’ll show you the footage.
What happens if I skip the liner repair?
Combustion gases can leak into the wall cavity, and the loose tile can block the flue and send carbon monoxide back into the house. It’s not a cosmetic issue. If you suspect liner damage, stop using the fireplace until it’s inspected.
