The liner is the part of the chimney that does the actual safety work, and it is the part homeowners know least about. It is the inner channel that carries heat and combustion gases up and out, keeping them away from the masonry and the wood framing that surrounds the flue. When a liner cracks, corrodes, is the wrong size for the appliance, or was never there at all, the chimney becomes unsafe to use no matter how good the brick looks from outside. PureVent Chimney Sweep replaces and installs liners across Columbus, OH, sizing each one to the fireplace, stove, or appliance it serves and installing it so the flue is safe and drafts properly.

What the liner does behind the scenes
Inside every safe chimney is a liner, and its job is to contain the heat and the byproducts of combustion so they travel straight out the top instead of seeping into the masonry or the framing. Older Columbus homes often have clay tile liners, which work well until heat, age, or a past flue fire cracks them, opening gaps that let heat reach the wood around the chimney and let combustion gases reach the living space. Newer and converted setups often use metal liners, which can corrode over time from the acidic moisture in flue gas, especially when an appliance is mismatched to the flue.
Some older homes have no liner at all, just bare masonry, which was acceptable generations ago and is not considered safe today. And many chimneys carry a liner that is simply the wrong size, often because a high-efficiency furnace or a wood insert was added without resizing the flue to match. An oversized flue lets gases cool too much and condense, while an undersized one cannot vent the appliance properly. Each of these is a real safety issue, and each is exactly what an inspection is built to find before it becomes a problem you can smell or feel inside the house.
Sizing and installing a liner the right way
A liner replacement only works if the liner is matched to what it vents, so we start with the appliance, not the catalog. A wood-burning fireplace, a wood stove or insert, a gas log set, and a high-efficiency furnace each need a flue of a specific size and material, and getting that match right is the whole point. We install stainless liners suited to the fuel and the appliance, insulate them where the installation and the code call for it so the gases stay warm enough to vent cleanly, and seal the system top and bottom so it performs as one continuous, safe channel.
A Columbus home converting from an open fireplace to an efficient insert is a common case, and it almost always needs a properly sized liner to vent the insert safely, which we handle as standard. When the liner is in, we confirm the chimney drafts the way it should, because a liner that vents poorly is not much safer than the failed one it replaced. The result is a flue that carries heat and gases where they belong, out above the roof, and keeps them away from everything they should never touch.
When a reline is genuinely the answer
Relining is significant work, so we only recommend it when the chimney actually needs it. If the inspection shows cracked clay tiles, a corroded metal liner, an unlined flue, or a liner mismatched to the appliance, a replacement is the safe path and we will explain exactly why with the camera footage in front of you. If the liner is sound and the issue is something smaller, a sweep, a cap, a crown repair, we will tell you that instead, because selling a reline that the chimney does not need is exactly the kind of upsell we refuse to do.
The reason we are careful here is that a liner is a safety component, not a cosmetic one, and a homeowner deserves a straight answer about whether theirs is doing its job. You get the footage, a clear explanation of the condition, and an honest recommendation, then you decide. When the work is done, the chimney is safe to use the way it was meant to be, and you have documentation of exactly what was installed and why.
It is worth saying plainly that a reline is an investment that lasts. A quality stainless liner, correctly sized and installed, is built to serve for many years, which means the cost is spread across a long stretch of safe, reliable use rather than being money spent on a recurring problem. For an older Columbus home whose original clay liner has reached the end of its life, a proper reline is often the single piece of work that turns an unusable or unsafe fireplace back into one the household can rely on through the winter, and that is exactly the kind of lasting result the work is meant to deliver.
