Chimney Liner Installation & Relining · San Antonio

A Failing Liner Won't Announce Itself. We Find It and Reline It Right.

Your flue liner is the safety-critical channel hidden inside your chimney, the part that carries intense heat and toxic gases, including carbon monoxide, safely up and out of your home. Most homeowners never see it, so a cracked, corroded, or missing liner can go unnoticed for years.

When it fails, heat can reach the wood framing around your chimney and gases can seep back into the rooms you live in. We check the real condition first, tell you honestly whether you need a reline, then install the right liner (stainless steel for most homes, cast-in-place where it fits), sized correctly and built to last.

Honest Look First

We assess the real condition of your liner and only recommend relining when you actually need it, no pressure, no invented problems.

The Right Liner, Done Right

Stainless steel or cast-in-place, matched to your chimney and appliance and installed to code, so it performs and lasts.

Safe to Burn, In Writing

You get a sound, sealed flue that carries heat and gases safely out, backed by our 3-year workmanship warranty.

The Right Liner for Your Chimney

One Job, Done the Right Way

Not every chimney needs the same liner. We match the solution to your flue, your appliance, and your home, then install it to code. Here's what that can look like.

Older Homes

Clay Tile Liners

The traditional liner in many older San Antonio homes. Durable, but prone to cracking over time, which is often why a reline is needed

Most Common Fix

Stainless Steel

The go-to reline solution: a durable stainless liner sized to your flue, safe for wood, gas, or an insert, and built to last for years

Where It Fits

Cast-in-Place

A seamless cement liner formed inside the chimney, a strong option that can also reinforce an aging structure where it's the right call

New Appliance?

Resize & Reline

Adding a new stove, insert, or gas appliance often means the flue must be resized. We reline it to match so it drafts and vents correctly

Not sure which you need? That's what the free assessment is for, we'll tell you honestly.

When a Reline Is on the Table

Signs Your Chimney May Need Relining

The liner is out of sight, but the warning signs aren't. If any of these apply to your chimney, it's worth having the liner checked before you burn again.

Cracked or Crumbling Liner

Pieces of clay tile or flakes of liner material showing up in the firebox usually mean the liner is breaking down inside the flue and no longer sealing it.

No Liner at All

Some older or altered chimneys were never properly lined. Without a liner, heat and gases have nothing safely containing them, a serious risk to fix.

After a Chimney Fire

Even a small chimney fire can crack or warp a liner in ways you can't see from below. A post-fire inspection tells you whether it still contains heat safely.

New Stove or Insert

Installing a new appliance often means the flue is the wrong size for it. A correctly sized reline is what makes the new setup vent and draft properly.

Failed Inspection

If an inspection or a home sale flagged the liner, relining is often the fix. We can tell you exactly what's needed to bring it up to standard.

Poor Draft or Odors

Smoke that won't draw, or gas and smoke smells indoors, can point to a compromised liner letting the flue leak instead of venting cleanly upward.

A liner is what stands between a working fireplace and a real hazard. If you're seeing any of these, get it looked at before the next fire.

Where the Liner Sits, and Why It Matters

Most homeowners have never seen inside their chimney. Here's how the parts fit together, and where that hidden, safety-critical liner does its job.

The flue liner is the inner channel that safely carries heat and gases up and out. When it cracks or corrodes, everything around it is at risk, which is exactly what a proper reline fixes.

Chimney Liner Questions

Chimney Liner FAQ

Straight answers about relining, what it costs to find out, and when you actually need it.

The liner is the inner channel of your chimney. It safely carries heat and toxic gases, including carbon monoxide, up and out of your home, and it protects the surrounding masonry and wood framing from that heat. When it's cracked, corroded, or missing, those protections are gone, which is why a sound liner is genuinely a safety item, not a luxury.
Common signs include tile or liner pieces in the firebox, poor draft, smoke or gas odors, a failed inspection, or having had a chimney fire. Adding a new stove or insert can also require it. The only way to know for sure is a look inside, which is what our inspection is for. We'll tell you honestly whether you need one.
Mainly stainless steel, which is the most common reline solution and works for wood, gas, or an insert, and cast-in-place cement liners where that's the better fit. Many older homes have the original clay tile liners, which are what we most often replace when they crack. We match the type to your chimney and how you use it.
It depends on the liner type, the size and height of your flue, and the condition of the chimney, so we don't quote a one-size number that turns out wrong. What we do give you is a free, honest estimate after we've actually looked, with no pressure and no upselling. You'll know the real scope before you commit to anything.
It can be. A cracked or missing liner can let heat reach nearby wood framing (a fire risk) and can let gases like carbon monoxide seep back into your living space. If you suspect your liner is compromised, the safest move is to hold off on burning and have it checked before the next fire.
Many stainless steel relines are completed in a day, depending on the chimney and access. Cast-in-place and more complex jobs can take longer. We'll walk you through the expected timeline as part of your estimate so there are no surprises on the day.
A quality stainless steel liner, properly installed and maintained, is built to last for many years, and our work comes with a 3-year workmanship warranty in writing. Keeping up with regular sweeps and inspections is the best way to get the full life out of it.
Often yes. Gas appliances still produce moisture and gases that need to vent properly, and an improperly sized or deteriorated flue can cause problems even with gas. If you're switching to a gas insert or appliance, the flue frequently needs resizing and relining to vent safely. We'll confirm what your specific setup needs.
