Fast, Reliable Chimney Liner & Rebuild Across Smithtown
Chimney liner replacement and rebuild work in Smithtown typically runs $2,800-$8,500 depending on scope, and most jobs are completed in a single day once materials are on-site. If you’re smelling smoke in your living room, seeing white efflorescence staining your brick, or your home inspector just flagged a cracked flue tile, the underlying problem is almost always a deteriorated liner or compromised chimney structure - and in Smithtown’s 50-70-year-old housing stock, it’s more common than most homeowners realize.
We’ve been answering calls from Smithtown since 1984. Our technicians know the difference between a Nissequogue River corridor chimney saturated by ground moisture and one on the north side of town taking direct spray off Smithtown Bay. That local knowledge changes how we diagnose the job and what materials we specify. When you call (844) 803-1545, a live person answers - not a queue, not an app - and we’ll get you scheduled for a Level-2 camera inspection with photos you can see and a plain-English verdict.
Why Hearthstone Chimney Co. Is Smithtown’s Preferred Chimney Liner & Rebuild Company
Smithtown homeowners don’t call us once. They call us when they buy the house on Bread and Cheese Hollow Road, again when they convert the oil boiler to gas, and years later when the crown finally gives out. That repeat relationship is built on doing the job right the first time - and standing behind it with the 90-Day Done Right Promise in writing, no arguing.
Our Level-2 inspections end with dated photos and a written verdict you can forward to your insurance company or real estate attorney. In a town where home sales move fast and inspectors routinely flag oil-to-gas flue mismatches on 1960s colonials, that documentation matters. We’ve walked anxious sellers through liner sizing requirements on tight closing timelines more times than we can count.
A live person answers our phones 24 hours a day, 7 days a week. Most of our Smithtown calls come from homeowners who tried a voicemail-only operator and waited three days for a callback that never came. That doesn’t happen here.
Our background-checked, uniformed technicians complete most liner and rebuild jobs in a single visit. The number on your upfront estimate is the number on your invoice - a square deal, no surprises.
Our Chimney Liner & Rebuild Services in Smithtown
Stainless Steel Liner Installation
For most Smithtown homes with deteriorated clay flue tiles, a stainless steel liner is the permanent fix. We specify DuraFlex and Olympia Chimney products sized precisely to your appliance - critical in this town, where oversized flues from oil-to-gas conversions collect acidic condensation and rot from the inside out. A properly sized stainless liner eliminates that mismatch, improves draft, and carries a lifetime warranty when we install it.
Flexible Liner Installation
Smithtown’s older colonials and Cape Cods often have offset flues or tight cleanout passages that rigid pipe won’t navigate. Our flexible liner installations use professional-grade corrugated stainless that bends through offsets while maintaining full structural integrity. We’ve run these through chimneys on Saint James border homes where the flue shifts six inches off plumb - still done right, and we stand behind it.
Liner Replacement
Sometimes the liner itself is intact but the surrounding structure has shifted or spalled. In Smithtown’s freeze-thaw environment, we’ve pulled intact clay tiles from chimneys where the mortar bed had turned to sand. Our Chimney Liner & Rebuild team evaluates whether the liner can be salvaged or needs full replacement, and we tell you straight - no upsell, no scare tactics. If replacement is necessary, we handle the permit coordination with the Town of Smithtown Building Department and schedule around your closing date if you’re selling.
Partial Chimney Rebuild
The top three to four feet of a Smithtown chimney take the worst beating - wind-driven rain off Long Island Sound, freeze-thaw cycling, and salt-laden air that accelerates mortar joint erosion. When the crown is cracked and the upper courses are spalling but the lower structure is sound, a partial rebuild with matching brick and our Chimney Cap & Crown in Smithtown is the cost-effective path. We rebuild with the same care we’d use on our own home on Main Street - Krafted right, Every time.

Trusted Brands We Service in Smithtown
We don’t substitute builder-grade materials to hit a price point. Our Smithtown trucks carry DuraFlex stainless liners, HeatShield cerfractory flue resurfacing products, and Famco chimney caps and fittings - the same brands specified by our Fireplace Services in Smithtown and major insurers. Because we stock these parts locally, most Smithtown liner jobs don’t wait on shipping. When your closing is in ten days or your boiler is shut down by the inspector, that turnaround matters.
Common Chimney Liner & Rebuild Problems We See in Smithtown Homes
- Oil-to-gas flue mismatch causing condensation damage. Thousands of Smithtown’s 1960s-1970s colonials were built with clay flues sized for oil boilers, then converted to gas. The oversized flue cools too fast, condensing acidic moisture that deteriorates tiles from the inside. We see this on homes from Kings Park border to Lake Ronkonkoma border - it’s nearly universal in that vintage.
- Freeze-thaw spalling on north-facing chimney faces. Chimneys on the north and east sides of Smithtown homes, especially those near Smithtown Bay, absorb repeated wet-dry-freeze cycles. The brick faces pop off in layers - spalling - and mortar joints erode to powder. A partial rebuild with proper crown drainage stops the cycle.
- Cracked crowns letting water into the flue system. The concrete crown is supposed to shed water past the chimney edge. In Smithtown’s stock of 50-70-year-old homes, these crowns are often poured too thin, unreinforced, or without proper overhang. Water enters, freezes, and opens cracks that reach the flue liner below.
- Efflorescence signaling chronic moisture wicking. That white powder on your brick is salt deposited by evaporating water. In the Nissequogue River corridor and low-lying neighborhoods near Jericho Turnpike, high groundwater and humidity wick through masonry year-round. Efflorescence means water is moving through the system - and your liner is at risk.

Smithtown pricing is comparable to Hauppauge and Kings Park, though north-shore homes near the bay sometimes require additional moisture remediation - vapor barriers, crown redesign, or brick matching - that can add 10-15% to a standard liner job. We price these items separately so you see exactly where the money goes.
Every liner and rebuild job is backed by our 90-Day Done Right Promise in writing - if it’s not right, we make it right with no paperwork and no arguing. Stainless steel liners carry manufacturer lifetime warranties when installed to specification. The warranty follows the home, not the owner, which matters in Smithtown’s active resale market.
