A new liner is the safety backbone of a chimney — we install and reline for unlined, damaged, and upgraded systems across Dallas, sized right.
The liner is the chimney's safety core — the smooth interior passage that contains the heat and byproducts of every fire and keeps them away from the surrounding structure. When a chimney is unlined, has a failed liner, or is being connected to a new appliance, installing the right liner is what makes the whole system safe to use. On Dallas's mix of century-old masonry and newer homes, liner installation ranges from bringing an old unlined flue up to modern safety to sizing a stainless liner to a new insert.
A liner has to be matched to what it's venting. Too large and the flue won't draft properly, so it runs cool and loads up with creosote; too small and it can't vent safely. We size the liner to the appliance and install stainless steel (or cast-in-place where appropriate) — durable, code-compliant, and built to last. Correct sizing is the difference between a liner that vents cleanly for decades and one that creates draft and creosote problems from day one.
An unlined or failed-liner chimney lets heat reach the surrounding masonry and framing, and lets combustion gases — including carbon monoxide — work through gaps into the home. It's one of the more serious findings a Level 2 inspection turns up, and it's exactly why a chimney gets flagged as unsafe to use. Installing a proper liner resolves it, restoring a safe, contained path for everything the fire produces. For older Dallas homes especially, it's a common and important upgrade.
Relining is a bigger investment than most chimney services because it's the safety backbone of the system — but it's a long-lasting one. Price depends on the chimney's height, the liner type and diameter, and the appliance it serves. You'll get a clear, itemized quote after an inspection confirms exactly what's needed. We size and install it correctly the first time, so it's a fix you don't revisit.

Common triggers are an unlined chimney (frequent in older Dallas homes), a cracked or failed clay tile liner, installing a new insert or appliance, changing fuels, or fire damage. A camera inspection confirms the liner's condition and whether it needs installation or can be repaired.
Typically stainless steel, sized to the appliance it vents, and cast-in-place liners where that's the right solution. Both are durable and code-compliant. The critical part is correct sizing — a liner matched to what it vents drafts cleanly, while a mis-sized one causes draft and creosote problems.
A liner that's too large won't draft properly, so it runs cool and builds creosote fast; one that's too small can't vent safely. Sizing the liner to the appliance is what makes it vent cleanly and safely for the long term, which is why we size before we install.
It can be. Without a proper liner, heat can reach the surrounding masonry and framing, and combustion gases including carbon monoxide can work into the home through gaps. It's a serious inspection finding and a common reason a chimney is flagged unsafe. A proper liner resolves it.
Repair restores a liner that's fundamentally intact but has damaged joints or sections — often cheaper. Installation (relining) is for chimneys that are unlined, have a failed liner, or need one for a new appliance. A camera inspection tells us which your chimney needs.
