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 Chimney Repair Services in Smithtown
Mortar Repointing
Most Smithtown chimneys built between 1955 and 1978 used lime-based mortar, which is softer than modern Portland cement mixes. After 50-plus years of Long Island weather, that mortar has turned to sand in a lot of places. We grind out the failed joints and pack in fresh mortar matched to the original brick’s strength and color. In Smithtown, repointing typically runs $28 to $45 per square foot of chimney face, depending on access and how much joint depth has been lost.
Spalling Brick Repair
Spalling is what happens when water gets into brick faces, freezes, and pops the surface off. Smithtown gets roughly 100 freeze-thaw cycles a year, and salt-laden air from Long Island Sound doesn’t help. You’ll see it most on the top four or five courses of chimney and any brick near a failed crown. We cut out the damaged units, match replacements from local masonry suppliers, and set them in mortar that won’t fail in five years. Expect to pay $45 to $85 per brick replaced, including labor and materials.
Chimney Waterproofing
If we’re repointing or rebuilding a Smithtown chimney anyway, waterproofing is the step that keeps you from calling us again in three years. We use a vapor-permeable masonry sealer that lets the brick breathe while blocking bulk water, which is critical for North Shore humidity and salt exposure. A standard waterproofing application on a Smithtown chimney runs $295 to $495 depending on height and square footage. This is not paint. It’s a penetrating treatment that lasts 10 to 15 years when applied correctly.
Flashing Repair
Flashing is the sheet metal where the chimney meets the roofline, and in Smithtown it fails in two ways: rust-through from salt air and separation from freeze-thaw movement. When flashing leaks, the damage often shows up inside the house as water stains on the ceiling near the fireplace or boiler closet. We repair or replace flashing with copper or aluminum, properly counter-flashed and sealed. In Smithtown, flashing repair runs $350 to $900, with the higher end for copper work and steep roof access in older split-levels.

Trusted Brands We Service in Smithtown
We stock parts and install products from Gelco, Olympia Chimney, and DuraFlex because we’ve watched these components hold up in Smithtown’s salt air better than cheaper alternatives. When your damper, cap, or liner connector has rotted out after eight years of North Shore exposure, we put in something that will actually last. For relining jobs, DuraFlex stainless liners are our default for oil-flue conversions and shared-chase repairs. We carry common sizes on the truck, which means most Smithtown repairs don’t wait on a parts order.
Common Chimney Repair Problems We See in Smithtown Homes
- Shared-chase cross-contamination: In the Kings Park and Nesconset subdivisions, many original builders ran the oil-boiler exhaust and the fireplace flue through the same unlined brick chase with no tile liner in either channel. When one side’s draft fails, boiler exhaust can backdraft into living spaces. This is the single most common reason Smithtown homes fail a real-estate inspection.
- Salt-corroded dampers and caps: Long Island Sound puts salt in the air year-round, and it eats galvanized steel parts faster than inland Suffolk communities ever see. We regularly pull dampers from Smithtown chimneys that are rusted solid after less than a decade. Stainless replacement solves it permanently.
- Crown cracks from freeze-thaw cycling: Smithtown’s position on the North Shore means wet winters and sharp thaws. Water pools in hairline cracks, freezes overnight, and pries them wider. After a few seasons, the crown is structurally compromised and water starts working down into the chimney body.
- Spalled brick on south and east faces: The prevailing weather exposure in Smithtown hits one side of the chimney harder than the others. We see disproportionate spalling on windward faces, which tells us the chimney was never waterproofed. Once a brick face pops, the softer interior brick underneath erodes quickly.

FAQs - Chimney Repair in Smithtown
The relining need comes from a construction shortcut in Smithtown’s 1950s through 1970s housing boom. Builders ran oil-boiler exhaust and fireplace flues through a single unlined brick chase with no tile liner in either channel. Over 50 years, acidic oil exhaust and moisture eat away the parging inside, and the masonry itself deteriorates enough that no amount of brushing makes it safe. A full stainless reline is usually the only repair that passes a Level 2 inspection and prevents cross-contamination between the two flues. Call (516) 968-5380 and we’ll run a camera down the flue and show you exactly what’s in there before anyone recommends a liner.
Salt-laden air from the Sound corrodes any exposed metal on your chimney, dampers, caps, liner connectors, and flashing, and it accelerates rust-through to under a decade in some cases. At the same time, the freeze-thaw cycle count along the North Shore, roughly 100 per year, pries apart lime-based mortar joints in 1960s common brick. The combination means Smithtown chimneys fail from both chemical and mechanical stress at once. The fix is stainless components where metal is exposed, repointing where mortar has gone soft, and waterproofing on the masonry itself.
A shared chase means your oil-boiler flue and your fireplace flue run through the same brick structure with only a thin dividing wall, or sometimes no dividing wall at all, inside. In Smithtown’s split-level homes from the 1960s and 70s, many of these chases had no tile liner, so the two channels are separated by crumbling parging and loose brick. When the stronger draft from one side pulls negative pressure on the other, boiler exhaust can backdraft into your living room. The fix is a dedicated stainless liner for the boiler and an insulated channel for the fireplace. We did exactly that job in Nesconset recently. The home passed its Level 2 inspection on the first recheck and the buyer closed without a chimney contingency.
Your crown is cracking because of Smithtown’s freeze-thaw cycle, not because you got a bad patch job. Water sits in micro-cracks, freezes at night, and expands. Repeat that 100 times a winter and the cracking compounds. If someone patched it with a thin cement overlay instead of rebuilding with a proper overhanging crown and a flexible membrane underneath, it’ll fail again in two or three years. A rebuilt crown with the right materials and a waterproofed top face typically ends the cycle. Expect $750 to $1,300 depending on chimney size and roof access.
Yes, and this is the most misunderstood point in Smithtown. Your oil boiler exhausts through that chimney every time the heat kicks on, so that flue gets more use than a fireplace would. Oil exhaust is acidic, and in an unlined mid-century chase, it eats the interior masonry continuously. If the parging inside fails, exhaust leaks into wall cavities or backdrafts into the house. Once a year, burn or no burn. Chimneys break in the off-season too. A camera inspection with us includes a photo report, and we’ll tell you plainly whether the flue can wait or needs work now. Call (516) 968-5380 to set one up.
