Chimney Relining & Flue Liner Repair
The flue liner is the inner channel that safely contains heat, embers, and combustion byproducts and carries them out of the home. When a liner is cracked, deteriorated, wrong-sized, or missing, the chimney cannot do its core job safely. Relining restores that protection, and it is also what makes many older chimneys compatible with a new appliance.
Why a liner matters
A liner protects the surrounding masonry and framing from the heat of the fire, keeps combustion gases from seeping through cracks into the home, and provides a smooth, correctly sized path for good draft. A cracked clay tile liner, common after a chimney fire or decades of use, breaks that protection even when the chimney looks fine from outside.
This is not a cosmetic component. A compromised liner is a genuine safety issue, which is why a camera inspection so often leads to a relining conversation.
When relining comes up
Relining is considered when an inspection finds a cracked or deteriorated liner, when there is no liner or an unsafe one, after a chimney fire, or when connecting a new appliance whose output requires a different liner size or material than what is there. Matching the liner to the appliance and fuel is central to doing it correctly.
Stainless steel liners are a common solution for many wood, gas, and oil applications; the right choice depends on the system. We determine what suits your chimney and appliance rather than applying a default.
Doing it correctly
A relining is only as good as its sizing, material, and installation. An oversized or undersized flue drafts poorly; the wrong material for the fuel is unsafe. We assess the appliance, fuel, and chimney together, and any related code or permit requirements are determined for the property. We are candid that this is a system decision, not a one-size product.
Signs a liner needs attention
- Cracked or displaced liner tiles on a camera scan
- No liner or an unsafe existing liner
- Damage after a chimney fire
- Connecting a new appliance with different flue needs
- Draft problems tied to flue size
- Combustion odor seeping into the home
Relining considerations include
- Matching the liner to the appliance and fuel
- Correct sizing for good draft
- Choosing the right material (clay, cast-in-place, stainless)
- Confirming the chimney's condition first
- A camera scan to verify the interior
- Any code or permit requirements for the property
Serving St. Louis & Kansas City
We provide chimney relining & flue liner repair across both of our home regions — the St. Louis metro, including the Metro East communities in Illinois, and the Kansas City metro on both the Missouri and Kansas sides — generally within about 65 miles of each city. Wherever you are, the approach is the same: we look at the actual system on site, explain what we find in plain terms, and lay out the options before any work begins. We use cautious, honest language about what we can and can't determine, and we don't quote a price or promise a fix for a problem we haven't assessed in person. Each metro has its own direct phone number, so you always reach the right place, and we're available around the clock to take your call and get you on the schedule.
The scope of a repair depends on what has actually failed and how far the damage extends, how the chimney is built and how easily it can be accessed, and whether water has been getting in long enough to affect more than the visible area.
Keeping ahead of it
Repairs tend to be smaller when they're caught early. A minor crown crack, a bit of open joint, or a slightly rusted cap is far more contained than the spalled brick, interior leaks, and larger rebuilds that follow seasons of unaddressed water. A yearly look is the reliable way to catch these while they're small.
Questions
Chimney Relining & Flue Liner Repair FAQs
How do I know if I need a new liner?
A camera inspection is the reliable way to see liner condition. Cracked or missing liners, damage after a chimney fire, or connecting a new appliance are the usual triggers.
What are liners made of?
Common options include clay tile, cast-in-place, and stainless steel. The right choice depends on the fuel and appliance; we match the liner to your system.
Can I use my fireplace with a cracked liner?
A cracked liner can let heat and combustion gases reach areas they should not, so it should be assessed before continued use. We explain what we found and the options.
