We Keep Milwaukee Safer With Expert Chimney Relining Services

The chimney liner is the clay or metal interior of your chimney system. It’s what takes the smoke and byproducts of combustion from the fireplace and ushers it up and out of the home. Unfortunately, as strong and durable as these liners are made to be, they can become damaged over time. As a result of moisture, heat, and creosote buildup, they might develop cracks and gaps, flake and erode, or – if they’re metal – they may rust and corrode.

If your chimney liner is damaged, you might notice a few different issues:

  • Poor draft
  • Smoky fireplace
  • Poor fireplace performance

But liner damage isn’t always obvious. And the problem is: it’s highly risky to use your fireplace with a damaged liner.

Can You Use Your Fireplace if Your Chimney Liner Is Cracked or Damaged?

We often get asked, “Can I use my fireplace if my chimney liner is cracked or damaged?” – and the answer is No, you shouldn’t take the risk. The reason being that when you have holes, cracks, gaps, or thinner areas in the liner, the liner simply won’t provide the level of protection it should against heat transfer, house fire, and carbon monoxide.

These cracks and gaps can allow heat from the fire, stray sparks, and hot ash to meet with nearby framing and walls. Over time, the wood will dry out and a fire could break out in the home.

The good news is: If you’re keeping up with annual chimney inspections as the National Fire Protection Association (NFPA) and Chimney Safety Institute of America (CSIA) recommend, you’ll know if you have liner damage. That way, you can take the necessary steps to fix the issue and start enjoying a safer, more efficient fireplace again.
