Is It Time To Have Your Furnace Or Water Heater Relined? Leonard & Sons Is The Company To Call

The chimney connected to your fireplace or stove isn’t the only chimney working hard to prevent fire and carbon monoxide hazards — your furnace and water heater chimneys are working hard to vent, contain, and protect as well. And like the chimney venting your fireplace or stove, the chimney venting your water heater or furnace can be damaged and need relining. Just as you would trust Leonard & Sons to reline your fireplace’s chimney, you can count on us when you need to have your water heater or furnace venting relined as well.

We’re Chimney Safety Institute of America (CSIA)-certified chimney and venting specialists and we’re experienced and equipped to install a new liner for your furnace or water heater. Whether you have a gas, oil, or wood-burning water heater or furnace, we’re here to help.

When To Reline

  • When it comes to safely venting your water heater or furnace, one of the most important things is ensuring that the flue is the right size for the attached appliance. If your flue is incorrectly sized, we can reline with a liner that will improve safety and performance.
  • If you change fuel types, your existing liner may not be equipped to take on the heat or byproducts produced, and you may need to have the flue relined.
  • Corrosive byproducts are produced by all fuel types, and if the flue is not regularly cleaned, these byproducts can lead to holes, cracks, flammable buildup, and erosion, leaving the flue liner ineffective and unsafe.

If you think you may need to have your furnace or water heater venting relined, give Leonard & Sons Building Service a call at 847-658-7659 or fill out our online scheduling form. We have years of experience and we’re knowledgeable and up to date on all the latest safety information and codes.
