About Chimney Lining

Categorized: Basics, Liners | No comments

A chimney serves as the exit path for harmful gases, dangerous smoke, and toxic fumes that are produced as wood is burned in a fireplace. A chimney lining helps to ensure that these toxins successfully escape your home. Without proper lining, smoke and gases can absorb into the bricks and stone of your chimney increasing the risk of fire, chimney build up, and possible toxic contamination of your home. That’s why it is important to maintain and replace chimney lining on a regular basis. Chimney liners are subject to very high temperatures and volatile chemicals so they must be replaced from time to time.

Many choose to have their chimneys professionally re-lined when needed. Chimney sweeping companies generally offer a flue lining chimney service as well. This is the best option for people who are not particularly handy or don’t have much experience in home improvement because professionals have the right equipment to get the job done quickly and efficiently. Some consumers may choose to attempt this project on their own. It’s possible to do it yourself to save some money if you do a bit of research and planning first. This is a delicate job so some organization is necessary. Lining a chimney is a relatively simple process, although it does require hard work and is often a very dirty job.

The first step to lining a chimney is to clean the chimney. Cleaning the chimney involves removing any obstacles and obstructions within the chimney. Additionally, soot buildup and residue must be cleaned from the inner walls. Remove any broken liner pieces or existing lining. A new chimney liner should never be installed without first ensuring that the chimney itself is perfectly clean and clear. You can clean it yourself with a chimney brush or hire a chimney sweep.

Next, the new lining system must be put together. Often, this involves attaching several pieces of tubing using rivets and cement. The end of the lining must be molded to the shape of your current chimney damper to allow a tight seal. This is a delicate job so some organization and planning is necessary. It is easier and safer to assemble the liner while on the ground and then to transport the fully assembled lining to the chimney for permanent placement. The liner will be very long and awkward to carry. It is best to enlist several people in the transportation process for optimal safety.

The lining must then be inserted into the chimney. Often this is a time consuming process that involves slowly feeding the section of tubing into the chimney. Be careful while inserting the liner to move slowly and carefully. Chimney lining is very rigid and can easily break or crack especially at the seals. Plan on setting aside several hours for this entire process so that you won’t feel rushed and damage the liner. Any open spaces can create big problems down the road. Keep inserting the lining into the chimney very carefully until it is securely into position.

Once the lining is in place, secure the lining to the chimney by attaching it to the damper and completing the installation by attaching the chimney cover. The cover will protect your home from moisture from various outside elements.

It is important to install the liner correctly to prevent chimney fires and excessive smoke. You should carefully research chimney flue lining installation before attempting to install a system yourself. Professional installation is the easiest and safest method for replacing or installing lining. If you do choose to install it yourself, you may want to have an inspector come to ensure that you have done it correctly and there are no potential dangers. Although you will have to pay for the inspection, it is much cheaper than hiring someone to install it and it will give you peace of mind that there is no possibility of harm to your home or family arising from the liner.
