Cracked Century-Old Clay Tile
Freeze-thaw cycles and past chimney fires split tile liners. Gaps let heat and carbon monoxide into the masonry instead of up and out.

Relining Chimneys in St. Louis
Most St. Louis chimneys were built when clay tile was the standard, and plenty of pre-war city stacks were never lined at all. After a hundred winters those tiles crack, shift and open gaps that let heat and combustion gases reach the brick and the framing around it. A camera scan is the only honest way to know — from the ground everything looks fine.
We show you the footage before we quote anything. If the flue needs relining we install an insulated stainless liner sized to the appliance, whether that is a fireplace in a Tower Grove two-family, a furnace venting into an old South City stack, or a suburban unit in Kirkwood, Chesterfield or St. Charles.
Warning Signs
Why St. Louis Flues Need Relining
The liner is the part of the chimney you can never see from the room — and the part that keeps heat and combustion gases away from your home's framing.
Unlined Pre-War Chimneys
Many older St. Louis chimneys have bare brick inside. Modern appliances cannot safely vent into them without a liner.
Oversized Flues for Modern Furnaces
A high-efficiency furnace venting into a huge old flue never warms it, so acidic condensation eats the masonry from the inside. A correctly sized insulated liner fixes the draft and the damage.

What We Install
Liners Sized, Insulated and Sealed Correctly
Insulated Stainless Steel Relining
A continuous stainless liner sized to the appliance, wrapped in insulation where clearance requires it, running from the appliance connection to the top plate — no joints inside the chimney to leak.
Furnace & Water Heater Liners
Correctly sized liners for gas appliances still venting into an old masonry flue, which fixes both the condensation damage and the weak draft that caused it.
Top Plate, Cap & Crown Work
The reline is finished with a sealed top plate and cap so water cannot get between the liner and the masonry. Crown repair is quoted in the same estimate when it is needed.
Camera Scan Before and After
We record the condition of the flue before we quote and after we finish, so you see exactly what you paid for instead of taking someone's word for it.
How It Works
From Camera Scan to a Safe Flue
1. Tell Us What's Going On
Failed inspection, tile pieces in the firebox, smoke smell, a home sale deadline — tell us and we book the camera scan.
2. Camera Scan the Flue
A camera goes the full length of the flue. You see the footage and the actual condition of the liner before any price is discussed.
3. Size the Liner
The liner is sized to the appliance and the flue — not guessed. Wrong-size liners cause draft problems that are worse than the original issue.
4. Written Price First
You get the liner type, insulation, top-plate work and total price in writing before we order anything.
5. Install & Verify
The liner is installed, connected, sealed at the top, and re-scanned. You get photos and footage of the finished flue.
Honest Pricing, No Fake Numbers
Nobody can quote a reline over the phone without knowing the flue height, diameter, insulation requirement and appliance. Anyone who does is guessing — and the guess usually rises once they are on site. We scan first, then give one written price that does not move.
If the scan shows your liner is sound, we tell you so. A reline you do not need is the most expensive repair there is.

Answers Before You Commit to a Reline

(682) 217-3577It depends on the flue height, the liner diameter, whether insulation is required and what appliance it serves. A short furnace liner and a full insulated fireplace reline are very different jobs. We scan the flue first and give a written price before ordering anything.
The reliable answer comes from a camera scan of the flue. Common clues are pieces of clay tile in the firebox, a smoke or gas smell, a failed Level 2 inspection, or a furnace that back-drafts. Visible cracks and open joints on camera confirm it.
A quality stainless liner, correctly sized and installed, typically lasts decades and is usually sold with a long manufacturer warranty. Thin or wrongly sized liners fail early, which is why sizing and material matter more than price.
No. A cracked liner lets heat and combustion gases reach combustible framing behind the masonry, and it is one of the few findings that make a chimney unsafe to use until it is corrected.
Often yes. Modern high-efficiency gas furnaces and water heaters vented into an oversized old masonry flue produce condensation that destroys tile and mortar. A correctly sized liner solves the draft and the damage.
Most straightforward relines are done in a day once the correct liner is on hand. Unusual flue sizes, offsets and factory-built components may need an ordering window, which we tell you about after the scan.

Most straightforward stainless relines are completed in a day once the right liner is on hand. Odd flue sizes, offsets or older masonry may need an ordering window, and we tell you which after the inspection.
