Relining a masonry flue the listed way
Sizing starts with the appliance manual
A liner is sized to the appliance it serves, not to the opening at the top of the chimney. The DuraLiner instructions, for example, say the liner shall be no smaller than the size the appliance manufacturer specifies. Other listed systems carry similar wording in their own manuals.
That is why we ask for the make and model before we quote. With the appliance manual in hand, the required flue size becomes a documented figure rather than an estimate. If the manual is missing, we look for the model label on the unit and work from the published instructions.
Why liner size affects draft
Flue gases rise because they are warmer than the air outside. A flue far larger than the appliance needs can let those gases cool and slow on the way up. Liner makers note that correct sizing matters most where flue gases run cool.
This is why an oversized liner is not a safety margin. We size to the appliance instructions and the listing, not to the largest pipe that fits. The estimate names the size and the reason for it, so it can be checked against the manual.
Signs that point toward a relining assessment
Several observations can lead to a relining conversation. Pieces of clay in the fireplace, smoke spilling at the appliance door, or an inspection note about the lining are typical ones. None of them proves a liner is needed.
We treat each sign as a starting point. The inspection looks for the cause, which may be the lining or another part of the system. If relining is the answer, the estimate says which finding supports it and how the liner addresses it. Some signs point elsewhere, and we say so when they do.
Sealing the wall opening around a tee
When the liner connects through the chimney wall, the gap around the tee branch has to be closed. Liner manuals describe the grout or mortar and the trim used at that opening. A loose opening can leak air or flue gases into the room.
We finish the wall opening the way the system's instructions describe. The estimate states whether the opening needs enlarging or repair first. The room side is cleaned when the connection is complete, and the trim is left square to the wall. A gap left open would defeat the purpose of the tee.

Common questions about a new flue liner
Is a stainless liner suitable for any fuel?
Not automatically. The listing decides which appliances and fuels a liner may serve, and two stainless products can carry different listings. We name the listing in the estimate and match it to your appliance manual before anything is ordered.
Does relining change how my chimney looks from outside?
Usually only the top changes, where the top plate and the liner cap sit above the crown. If a wall connection is involved, the tee opening is finished and sealed. We describe any visible change in the estimate before work starts.
What if my appliance needs a vent the chimney cannot provide?
Some appliances vent under pressure or condense their flue gases, and the chimney liner standard excludes those types. Their manuals specify their own vent systems. We explain this before any liner estimate is written, so nothing is bought in error.
