Chimney liner installation for homes in Southport

When clearances cannot be confirmed

Clearances are not always visible. One stainless liner's instructions state that if the proper clearances cannot be determined, the liner must be installed with an approved insulation wrap.

We would rather say that plainly than assume the framing sits where it should. If insulation is required for your chimney, the estimate says so and gives the reason in a sentence you can check. If more access would settle the question, such as an attic hatch we could not reach, we tell you that too, so you can decide which way to go.

When a round liner is shaped oval

If a round liner of the size an appliance needs will not fit the flue, a flexible liner can be formed into an oval to pass through. The instructions warn that ovalizing changes the cross-sectional area.

We check the shaped liner against the appliance's requirement instead of assuming the nominal diameter still applies, and we show that check in the estimate. If an oval liner would fall short, we explain the other options, such as removing old tile to make room for the round size.

How the installation day runs

Relining day follows a set order, and we tell you the plan the day before, including when the fireplace and the roof will be in use and roughly how long each stage takes for your chimney.

• The flue and smoke chamber are cleaned
• The route is proven with a test piece or guide cone
• Insulation, where required, goes on the liner
• The liner is lowered from the top
• The base connection is made and checked
• The top plate and liner cap are fitted and fastened

Liner cap or chimney cap

A liner cap covers one flue opening as part of the liner system. A chimney cap covers the flue from the crown, and on some chimneys covers several flues at once. Both can exist on one chimney.

If your chimney cap also needs replacing, it is priced as its own item, and we make sure the two parts fit together. The words get mixed up often, so the estimate names each part and shows which one the relining includes.
