Chimney Relining and the Different Kinds of Flue Liners

The best way to prolong the life expectancy of a chimney is to make sure that the flue and the flue liner is in perfect condition. The flue is one of the most vital parts inside the chimney and, quite honestly, it could get a bit pricey to get a new flue. Any homeowner wouldn’t just squander their money without knowing why it needs to be replaced and what the options are for a new set of chimney liners. It is our job here at Magic Sweep Corporation to give you all the information we have about the flue and chimney relining. Rest-assured that you will soon have a good idea on what it’s all about and maybe even save up on a few extra bucks.

What is a Flue and a Flue Liner?

The flue liner in your chimney doesn't last forever. Depending on the damage, you may need to repair cracks or replace it altogether.

The flue liner in your chimney doesn’t last forever. Depending on the damage, you may need to repair cracks or replace it altogether.

The chimney is the place where the smoke, that comes from open combustion in the fireplaces, passes to go out into the open environment. The structure is vertical and the space inside it is called the flue. It is the part where all the unwanted smoke and air passes with the help of the flue liner.

The flue liner is the part that is attached to the walls of the flue. It’s essential because it helps channel heat, smoke and gases to the outside. It also blocks the heat from the combustion in the fireplace from starting another fire inside the chimney. This is very possible especially when there are thick layers of creosote in the chimney.

It starts to crack or crumble because either it has been used it too much, especially during winter, or there is too much air pressure. In most cases, this cannot be prevented because naturally these parts start to deteriorate over time. This is when you need to have your chimney relined before attempting to use it again.

How Do I know that I Need to Have it Fixed?

Replacing the flue liner or chimney relining is not limited to the two reasons above. Sometimes this is needed because of one of the following situations:

  • Natural calamities like earthquakes and storms
  • Accidental chimney fire
  • You have an older version of chimney which originally did not have a flue liner installed
  • Resizing because you have a new appliance
  • Too much creosote build-up inside the chimney

Once you are in any of these situations, our licensed CSIA-certified sweeps will have to do a Level II Inspection where we use a special kind of camera to see what the problem really is and why there is a need for replacing the flue liner.

Let me elaborate more on one of the situations mentioned above, the part about living in an old-fashioned home. When you live in an old home, tendencies are your chimney does not have a flue liner. Somehow, it was designed that way—to function without the flue liner. But after years of tests and experiments, having a flue liner has become a need and no longer just a want inside the chimney; sort of like a requirement. This is because of the fact that it can really help control the heat and prevent it from re-igniting a flame in the wrong place while the combustion process is happening.

Are there Different Kinds of Flue Liners?

There are three kinds of flue liners. The first one is the Clay tile liner. These liners are budget-friendly and can live up to fifty years or more. Maintaining it only needs regular cleaning. They are usually installed once a chimney is installed.

The second one is Cast-in-Place liner. These liners are cemented onto the flue and can withstand a great amount of heat and can protect itself from harmful substances. Also, due to its outstanding insulation properties, less creosote is produced. They can also live up to fifty years and need the expertise of a professional sweep to properly install it.

The last one is the Metal flue liner. These are made in stainless steel and can really protect the inside from fire. Among the three, this is the most expensive because they come in flexible and rigid forms. Big-time companies and industries say that the investment is actually worth it—to the very last cent.

Chimney relining is very important because it can protect your home and your health. Magic Sweep Corporation is more than willing to do the job for you at a very reasonable price. Call us now and we can tell you more.
