The liner is the inner channel of the flue, and it is the single most important safety part in the chimney. Its job is to hold in the heat and the combustion gases and carry them safely up and out, away from the wood framing wrapped around the chimney and out of the rooms you live in. When a liner cracks, opens at the joints, or is missing entirely, that protection is gone, and the chimney turns into a real fire and carbon monoxide hazard. DraftWorks Chimney Sweep replaces chimney liners across Brooklyn Heights, OH, fitting a correctly sized stainless steel liner or repairing the existing one so the flue is safe to use again.
- Stainless steel liners sized to the appliance
- Cracked or gapped clay tile liners replaced
- Insulation added where the spec calls for it
- Liners matched to fireplaces, inserts, and stoves
- Fire-damaged liners assessed honestly
- Camera-verified safe flue when the work is done
Why a failed liner is the one thing that cannot wait
Many of the older Brooklyn Heights chimneys were built with clay tile liners, lengths of fired clay stacked up the inside of the flue, and clay does not hold up forever in this climate. A chimney fire can crack the tiles in a single event from the sudden, fierce heat. The freeze-thaw cycle and the everyday heating and cooling of normal use pull the mortar joints between the tiles apart over the years. And some of the oldest chimneys were built with no liner at all, just bare masonry standing in for the flue. Any of these leaves gaps where heat and gases can escape the channel, and that is not a problem you can put off, because every fire lit over a failed liner is a risk to the house and to the people asleep inside it.
The danger runs on two fronts at once. Heat or flame escaping a cracked liner can reach the combustible framing built around the chimney and start the very structure fire the chimney was supposed to prevent. And a gapped liner can let carbon monoxide, the colorless, odorless gas that wood and gas burning gives off, leak into the home instead of venting safely up and out. A camera inspection is how we confirm whether your liner has actually failed, and where it has, replacement is not an upsell. It is the repair that makes the fireplace usable again without putting the household at risk.
How we run a new liner down a Brooklyn Heights flue
The modern answer to a failed liner is a stainless steel liner, a continuous metal pipe run down the full length of the flue and connected correctly at the appliance and again at the top. Unlike a stack of clay tiles with joints between every section, a stainless liner is one seamless channel, which is why it has become the standard for relining work. We size it to the appliance it serves, because a liner too large for the fireplace or stove drafts poorly and a liner too small chokes it, and getting that sizing right is the line between a flue that pulls cleanly and one that smokes and lays down creosote fast.
Where the spec calls for it, we insulate the liner, which sharpens the draft, helps the flue stay warm enough that creosote condenses less heavily, and adds a layer of protection between the hot liner and the surrounding masonry. The work is matched to whatever you are venting, an open fireplace, a fireplace insert, or a freestanding stove, since each carries different requirements. When the relining is finished, we run the camera back up to confirm the new liner is sound and continuous, so you and we can both watch the flue prove itself safe before the first fire ever goes in.
What a sound liner gives you back
A properly relined flue hands you back a fireplace you can use without wondering what is happening behind the masonry. The heat and gases are held in and carried out the way they should be, the framing around the chimney is shielded, and the carbon monoxide risk a gapped liner carries is closed off. A correctly sized liner also draws better than a damaged or oversized one, which means fires light and burn cleaner, the room stays clear of smoke, and the flue gathers creosote more slowly because the smoke is moving up and out at the right pace.
We treat relining as the serious safety work it is, not as a product to move, which means we recommend it when the camera shows a liner has genuinely failed and we say plainly when it has not. If your clay liner is intact and your flue is sound, you will hear exactly that, and we will not conjure a reason to reline a chimney that does not need it. When relining is the right call, you get a written scope, a camera-verified result, and a flue you can light a fire in with confidence for years to come.
