The liner is the part of the chimney that does the real safety work, and it is the part most likely to have failed quietly on an older Elizabeth flue. It is the barrier that keeps the heat and the acidic byproducts of combustion inside the flue and away from the surrounding masonry and the wood framing of the house, and it has to match the appliance it serves. Elizabeth Chimney Services replaces chimney liners across the city, fitting a stainless steel liner sized and rated for your specific appliance when the original clay tile or metal lining has cracked, broken down, or was never right for what it now vents.

What the liner protects and how it breaks down
A flue liner has one job, and it is a critical one. It contains the heat and the corrosive condensation of every fire so they go up and out instead of into the masonry, the mortar joints, and the combustible structure pressed against the chimney. When the liner fails, those gases and that heat reach places they were never meant to, which is how a cracked liner becomes a slow carbon monoxide leak into the living space or a path for a flue fire to breach into the walls. A sound liner is not an upgrade, it is the line between a chimney that is safe to use and one that is not.
Liners fail in a few familiar ways on Elizabeth's older chimneys. Clay tile, the traditional lining in so much of the city's housing, cracks under the thermal shock of a flue fire or simply from decades of expansion and contraction, and once a tile cracks or a mortar joint between tiles washes out, the protection is breached. Older metal liners corrode, especially where an uncapped flue has been feeding them water for years. And a great many of these flues were sized for a coal or oil appliance and are now venting a modern high-efficiency furnace or a wood insert they were never matched to, which is its own hazard regardless of the liner's condition. The camera tells us which of these you are dealing with.
Matching the right liner to the flue and the appliance
A reline is not a single product, and getting it right means matching the liner to what it actually has to do. The correct diameter depends on the appliance, because a liner that is too large lets the flue gases cool and condense and drafts poorly, while one that is too small chokes the appliance and is unsafe. The right material and rating depend on whether the chimney serves a wood-burning fireplace or insert, a gas furnace or water heater, or an oil appliance, since each produces different heat and different byproducts. We size and spec the liner for your specific setup rather than dropping in a standard tube and hoping it suits.
We install stainless steel liners and insulate them where the appliance and the code require it, which improves the draft and keeps the surrounding masonry cooler at the same time. The liner runs continuously from the appliance connection to the top of the flue, sealed at both ends and fitted with the correct cap, so there are no joints or gaps for heat or gases to escape through. Done correctly, a stainless reline restores the chimney to a safe, properly drafting flue that is matched to the appliance it serves, often for the remaining life of the house.
Doing the reline by the book, not the shortcut
A reline is significant work, and we do it by the book rather than the shortcut. We pull the permit the job calls for, install to NFPA 211 specification, and run the camera both before and after so you can see the old liner that failed and the new one that replaced it. The permit and the inspection are not red tape, they are the documentation that protects the safety of the home, the validity of your insurance, and the resale of the property, and skipping them to shave a few dollars is simply not how we operate.
When the work is finished, the chimney is one you should not have to think about again for a very long time. You get the camera images of the completed flue, the documentation, and a crew that stands behind the installation in writing. We protect your home throughout, clean up completely when we are done, and confirm that the appliance drafts the way it should before we consider the job complete. A reline done right is a long-term fix, not a patch you will be revisiting.
