Your Flue Is the Part That Keeps Fire Safe
Inside every brick chimney is a flue — the passage that carries smoke, heat, and gases up and out. Most older chimneys have clay tile liners: square or rectangular clay sections stacked inside the brick. Over decades, those tiles crack from heat, moisture, and age. Cracked or missing tiles let heat and gases reach the brick and the wood framing around the chimney — that's a fire risk, and it's why building codes require an intact liner.
Relining means installing a new liner inside the chimney — giving you a safe, continuous flue without tearing the chimney apart.
Signs Your Liner Is Failing
- Pieces of tile in the firebox. If you find curved clay fragments at the bottom of your fireplace, your flue tiles are breaking apart.
- White staining on the outside brick (efflorescence). Moisture is moving through the masonry — often because the liner is compromised and letting condensation through.
- Poor draft or smoke coming into the room. A damaged liner changes the flue's shape and size, which can wreck the draft.
- A home inspector flagged it. This is the most common way liner problems get found — during a sale. If you're buying or selling, get it evaluated before closing.
Stainless Steel Liners: The Standard Fix
We install stainless steel liners — flexible or rigid depending on your chimney. Stainless is the industry standard for relines because it handles the heat, resists the acids in flue gases, and lasts decades. The liner is sized to your fireplace or appliance: too big and the draft is lazy; too small and smoke backs up. Sizing it right is part of the job.
Installation usually takes a day. We drop the liner down from the top, connect it to the appliance or firebox below, insulate around it (insulation keeps flue gases hot so they draft properly and reduces condensation), and finish with a new cap. In most cases the brickwork isn't touched at all.
When Relining Isn't Enough
Relining fixes the flue, not the structure. If the brick and mortar are also failing, a liner won't save the chimney — you may need a rebuild with a new liner included. During inspection we evaluate both and tell you which you actually need. Our liner comparison guide covers the options in detail.
