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.

AfterFast, Reliable Chimney Liner & Rebuild Across Elwood
Chimney Repair in Elwood for liner and rebuild work typically runs $1,800-$4,500 depending on whether you need a stainless insert, a full flue replacement, or partial masonry reconstruction. Most jobs are completed in a single visit after a Level 2 camera inspection confirms exactly what your chimney needs. If your Elwood home was built during the 1950s-1970s suburban boom and still has its original clay tile liner, there’s a strong chance it’s oversized or deteriorated from oil-to-gas conversion. Call (631) 776-4075 - a live person answers 24 hours a day, and we’ll schedule your camera inspection so you see what we see before any work is proposed.
We’ve been working on chimneys in Elwood and surrounding Town of Huntington communities for over 42 years. Our crews know the post-war Cape Cods along Cuba Hill Road, the ranches near Elwood Road, and the split-levels around the Elwood Middle School area. These houses share a common problem: brick chimneys built for oil-fired boilers now venting natural gas into flues that were never engineered for it. That mismatch is why we do so much liner work here.
Why Hearthstone Chimney Co. Is Elwood’s Preferred Chimney Liner & Rebuild Company
Elwood homeowners tend to stay put. They’ve raised families in these houses, watched the trees mature, and they don’t call a chimney company lightly. When they do, they’ve usually already had one bad experience with a contractor who recommended work they couldn’t verify. We built our reputation on doing the opposite.
Our Chimney Liner & Rebuild in Elwood service starts with a Level 2 camera inspection that ends with photos you can see and a plain-English verdict. No work is proposed without that documentation. Our 90-Day Done Right Promise is backed in writing with no arguing - if it’s not right, we come back. Dispatch and scheduling are coordinated from our New York City office, but the crew that arrives at your Elwood door is local, background-checked, uniformed, and trained to work on the exact chimney types found in this neighborhood.
A live person answers every call, 24/7. Not a voicemail. Not a callback queue. Most jobs are completed in a single visit, with no-hassle upfront pricing so the number on the estimate is the number on the invoice. We’ve earned the trust of Elwood homeowners by being the company that still answers the phone and still stands behind the work.
Our Chimney Liner & Rebuild Services in Elwood
Stainless Steel Liner Installation
The dominant chimney job in Elwood is not routine sweeping - it’s installing a properly sized stainless steel liner into a flue that was built for oil and never adapted for gas. Town of Huntington code requires a stainless liner for any active gas appliance flue, yet many Elwood homes were converted without one. A stainless liner from DuraFlex or Olympia Chimney gives your gas furnace or boiler a correctly sized, corrosion-resistant flue that drafts properly and meets code. We measure the appliance output, calculate the required flue diameter, and install the liner with a new top plate and our Chimney Cap & Crown in Elwood in one visit.
Flexible Liner Installation
Some Elwood chimneys have offset flues, corbelled smoke chambers, or minor shifts that make rigid stainless pipe impossible to feed through. For these, we use flexible stainless liners that navigate bends while maintaining the full cross-section your appliance needs. Flexible liners are especially common in the older Cape Cods near Elwood Road, where chimney construction was sometimes irregular. We source our flexible liners from DuraFlex and Gelco - professional-grade, not the thin-wall substitutes some installers use.
Liner Replacement
When a clay tile liner has deteriorated beyond repair - cracked tiles, missing mortar joints, or sections that have collapsed into the flue - replacement is the only safe option. In Elwood, this condition is frequently discovered during routine sweeps of 1960s ranches. The chronic condensation from high-efficiency gas appliances dissolves clay tile and mortar from the inside out, a failure mode we see constantly in this neighborhood. Our Chimney Liner & Rebuild team removes the damaged liner and installs a new stainless system, restoring the chimney to code-compliant condition.
Partial Rebuild
Not every Elwood chimney needs to come down. Often the damage is localized: the crown has cracked from nor’easter exposure, the top few courses of brick are spalling from salt-laden air off Long Island Sound, or the smoke chamber is eroded. We rebuild only what’s necessary, matching existing brick and mortar where possible. On a recent job near Cuba Hill Road, we rebuilt the top four feet of a 1962 chimney, installed a new Gelco cap, and dropped a stainless liner - all in one day. The homeowner paid for exactly what was needed, documented by camera evidence they saw beforehand.

Trusted Brands We Service in Elwood
We don’t use builder-grade substitutes. Our Elwood jobs are built with professional-grade materials from DuraFlex, Olympia Chimney, Gelco, and Famco - brands that supply the actual chimney industry, not the hardware store aisle. We stock common liner diameters and fittings locally, which means most Elwood homeowners aren’t waiting weeks for parts. When your chimney needs a new cap, a top plate, or a full liner system, the materials are already on our truck or available next-day. That matters in Elwood, where burning season arrives suddenly and an unlined gas flue is not something you want to run through a cold snap.
Common Chimney Liner & Rebuild Problems We See in Elwood Homes
- Oil-to-gas conversion left your flue unlined. Elwood’s post-war housing stock was built for oil boilers. When homeowners switched to natural gas, the oil flue was often abandoned without a liner insert. Town of Huntington code now requires a properly sized stainless liner for any active gas appliance flue, making this unlicensed condition one of the most common findings on our Elwood inspections.
- Chronic condensation dissolves clay tile from the inside. High-efficiency gas appliances produce cooler, wetter flue gases than old oil burners. In an oversized clay flue, that moisture condenses on the tile surface, leaching out minerals and accelerating cracking. We see this on nearly every 60-year-old Elwood chimney we camera.
- Nor’easter rain and salt air erode crowns and mortar. Elwood sits roughly 8 miles south of Long Island Sound. Salt-laden air accelerates mortar erosion and brick spalling faster than inland Suffolk County locations. Wind-driven rain drives directly into cracked crowns, letting water enter the flue and freeze-thaw the liner apart.
- Two-flue chimneys with one flue abandoned. Many Elwood homes have a single brick chimney with two flues - one for the old oil furnace, one for a 1970s fireplace. Homeowners often don’t realize the abandoned oil flue is still structurally compromised or that the active fireplace flue may share deteriorated mortar joints. Our camera inspection shows the condition of both.

FAQs - Chimney Liner & Rebuild in Elwood
Yes. Town of Huntington building code requires a properly sized stainless steel liner for any active gas appliance flue. Many Elwood conversions were done without one, leaving homeowners with an unlined, oversized flue that condenses moisture and deteriorates from the inside. We verify this with a camera inspection and install the correct liner if it’s missing. Call (631) 776-4075 to schedule - estimates are free.
You cannot see it from the fireplace or cleanout. Cracked clay tile is only visible with a chimney camera. During our Level 2 inspection, we feed a camera up the flue and show you the footage - cracked tiles, missing mortar joints, condensation streaking, or tile fragments at the bottom. No guesswork. No recommendations without evidence you can see for yourself.
Your house was built with one flue for the oil furnace and a second added later for a fireplace, common in 1960s-1970s Elwood construction, and our Elwood Fireplace Services team sees this setup regularly. When you converted to gas, the oil flue may have been abandoned without a liner. Even if it’s not actively used, its condition affects the structural integrity of the shared chimney. We inspect both flues and tell you exactly what each one needs - or doesn’t.
Third-degree creosote is a thick, tar-like, hardened coating that is extremely difficult to remove with standard brushing. It appears as glossy black buildup or puffy, popcorn-like deposits. In Elwood, we see it most often in fireplace flues that have been used for wood burning without regular sweeping. Removal requires rotary mechanical cleaning or, in severe cases, chemical treatment. We assess the severity during inspection and quote the removal method your flue actually needs.
Elwood’s location roughly 8 miles from Long Island Sound exposes chimney crowns to salt-laden air that accelerates mortar erosion, plus direct hits from nor’easter wind-driven rain. A crown built with standard mortar mix in the 1960s simply wasn’t formulated for this environment. We rebuild crowns with proper crown-specific concrete or apply a flexible crown sealant, and we always pair this with a quality cap to deflect water. The fix lasts when the materials match the actual conditions.
