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.
Famco Chimney Liner & Rebuild in Northport: What to Know First
We provide independent Famco chimney liner and rebuild service in Northport, with most jobs completed in a single visit and upfront pricing that matches the final invoice. A typical Famco liner replacement runs $2,800-$4,500 depending on flue height and diameter, while partial rebuilds start around $1,800. We’re not here to sell you a full rebuild when a liner swap will do, and we’ll show you the camera footage so you can see the difference for yourself.
This page is for Northport homeowners with a Famco liner, cap, or venting component that’s showing age, drafting poorly, or failing inspection. Maybe you bought the house with it already installed, or your contractor spec’d Famco years back. Either way, you need someone who knows the product line and won’t treat it like generic pipe. Call (631) 528-2501 - a live person answers, 24 hours a day.
How Famco Products Fail - and How We Fix Them
- Famco 304 stainless flexible liners in coastal Northport air. The 304-grade series was common in installations from the late 1990s through the mid-2000s, and it doesn’t hold up to salt-laden humidity the way 316L does. We see pinhole corrosion starting at the flex joints first, not the straight runs, because that’s where condensation pools. We replace with 316L or 316Ti flexible liner, properly sized to the appliance, and we document the old material with photos for your records.
- Famco rigid stainless tee assemblies on oil-fired systems. The tee body and cleanout cap on older rigid installations can warp from thermal cycling, especially if the burner was oversized for the flue. You’ll smell oil fumes at startup or see soot around the thimble. We pull the tee, check the surrounding masonry for pyrolysis damage, and install a properly gapped replacement with a sealed cleanout door.
- Famco galvanized vent connectors on water heater or furnace flues. These were budget-spec’d by plenty of Northport builders in the 1980s and 90s. Galvanized steel in a chimney flue is a timer; it rusts from the inside out where you can’t see it until it fails. We replace with aluminum or stainless connector pipe, properly pitched, and we run a camera to confirm the chimney flue itself isn’t compromised by years of acidic condensate.
- Famco chimney caps with integral spark arrestors on harbor-facing homes. The mesh on these caps packs with salt crust and creosote faster than standard caps, choking draft and backing smoke into the house on windy days. We see this on the older colonials near Northport Harbor more than inland. We clean or replace with a better-breathing cap design, and we’ll tell you honestly if the existing cap just needs a thorough cleaning instead of replacement.
- Famco liner top plates with failed sealant. The refractory sealant between the liner top plate and flue tiles degrades after 10-15 years, letting water run down between the liner and masonry. In Northport’s freeze-thaw cycles, that water spalls the flue tile from behind. We reseal with high-temp silicone or replace the plate, and we check the crown while we’re up there because the two problems travel together.
Our Famco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We book a Level-2 camera inspection with one of our background-checked, uniformed technicians.
- 2
Inspect and document. We run a camera the full length of the flue, photograph every defect, and give you a plain-English verdict. No jargon, no scare tactics. You’ll see what we see.
- 3
Parts decision. For Famco components, we source quality aftermarket equivalents from our trusted suppliers - DuraFlex, HeatShield, Gelco, Olympia Chimney, and Copperfield - when OEM Famco parts are discontinued or overpriced. We explain the trade-off and warranty implications before you decide.
- 4
Repair or rebuild. Most Famco liner replacements and partial rebuilds finish in one visit. We protect your floors, work clean, and don’t leave until the flue passes a smoke or draft test.
- 5
Written guarantee. Every job is backed by our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to find, no arguing.

FAQs
Original Famco warranties on most residential liners expired after 10-15 years, so age alone has likely ended coverage. As an independent Famco service provider, we don’t represent the manufacturer, but we use warranty-safe installation practices and document our work so any remaining coverage isn’t compromised by improper repair. If you’re unsure about your warranty status, we can help you read the fine print - call (631) 528-2501.
Some Famco series from the 1990s and early 2000s are discontinued, but we cross-reference to quality aftermarket equivalents from DuraFlex, HeatShield, and Gelco that meet or exceed original specs. We never install a part we wouldn’t use in our own homes, and we’ll show you the comparison before you decide.
The camera tells the story. If the clay flue tiles are sound and the masonry is structurally intact, a liner replacement usually solves it. If we find shifted tiles, spalled brick, or compromised mortar joints throughout, we’ll recommend a partial or full rebuild and show you exactly why. Some problems can wait a season; others shouldn’t. We’ll tell you which is which.
Most residential Famco liner replacements in Northport are completed in one day, typically 4-6 hours of on-site work. Tall chimneys on three-story harbor homes or jobs requiring extensive masonry prep may run into a second day. We give you a clear timeline before we start, and we don’t leave until the flue passes draft and smoke testing.
A failed or missing liner lets heat, sparks, and combustion gases contact combustible framing - the leading cause of chimney fires and carbon monoxide intrusion. In Northport’s older homes with balloon framing, that risk travels fast. That said, not every crack means emergency replacement. Our inspection tells you what’s urgent, what can wait, and what it’ll cost either way. Call (631) 528-2501 for a free estimate.
