Reasons to Reline Your Chimney
Relining of the chimney flue is the most practical and affordable way to repair a deteriorated or damaged chimney. Many times we don’t see the reasons relining is necessary until we either see the damage during an internal digital scan or the symptoms become too obvious for the homeowner to ignore any longer.
Reasons to Reline:
- To repair damage to the chimney liner caused by a chimney fire, water damage, lightning strikes or simple settling of the home.
- To upgrade older chimneys which were constructed without chimney liners. This is incredibly important for the safety and enjoyment of your system.
- To replace worn, deteriorated liners that may allow smoke, creosote or condensation to seep through the chimney walls.
- To properly size the chimney for a new appliance (for example: converting from oil to gas heat).
- Proper sizing–chimneys often need to be resized to perform properly. If an over-sized fireplace flue is used to vent a wood stove, excessive creosote and tar glaze may result. Additionally, the wood stove will not perform as well as it should if the flue is too big or too small.
As you can see there are many reasons for relining a chimney and they are not all because of needed repairs.
There are still many chimney systems that are operating without liners. Though codes and standards are clear that all chimney systems should be lined, many older chimneys were grandfathered in. However, for safety and efficiency reasons, an unlined chimney needs to be brought up to code and have a liner installed. If not, the creosote, smoke and debris of combustion will accumulate on the chimney walls and dangerous combustion gases could escape into the home. There is also great potential for a quick-spreading chimney or house fire.
For old and deteriorated liners, there is a process from Heatshield® that is quickly becoming a great alternative for ceramic or terracotta flue liners. You can get some additional information on our Heatshield® page.
Many times, people purchase a new appliance and think they can just hook it up to the existing flue liner — but that may not be the case. Pretty much any time you convert from one energy source to another, oil to gas, gas to wood, etc., you may be required to change out the liner. This could be because of the liner material, but could also be due to the size and output of the new appliance. Relying on a chimney company like Clean Sweep Of Anne Arundel County for Chimney Repair & Maintenance can help you determine what the requirements are well before you buy and install the new appliance. But, you have to contact us first!
If you don’t get a new liner when you change out an appliance, you will most likely have safety and performance issues. Every fireplace and wood stove has certain criteria that must be met for optimum performance.
When not met, there are always difficulties with:
- getting the fire lit
- keeping the fire going
- smoke & draft
- clearance to combustibles
The bottom line is that oil and gas furnaces, fireplaces and wood stoves are fine-tuned appliances — when treated well, they will give you a lifetime of pleasure and enjoyment. Unfortunately, when not properly cared for, they can be a real threat. Our job is to help you with the details so you can get the most enjoyment out of your system.
