Chimney Relining and Repair

Your chimney has a liner that protects the walls from heat elements. A chimney liner protects the inside from deterioration or corrosion over time. Often called the flue liner, this piece is generally made of ceramic, metal, or clay and comes in the shape of a coil. There are a couple of types of liners from which our technicians can choose. Smoother liners, called a double-wall chimney, have a few benefits. They are easier to clean and will improve your draft in the chimney.

Purpose of Chimney Relining

Aside from keeping your building in line with commercial and residential fire code regulations, there are a few benefits of lining your chimney:

  • A flue liner protects your chimney from heat to combustibles.
  • As combustibles may be present, a chimney liner protects against corrosion caused by these combustible elements.
  • A flue liner from Champion Chimneys will be the correct size to optimize the flow of air and the expulsion of gases.

How Our Technicians Reline Your Chimney

It’s best to hire a professional technician to reline your chimney as the lining material is extremely sharp, and roof work can be dangerous. Our Maryland chimney sweep technicians will take these general steps to reline your chimney.

Our technicians will bring chimney coil lining to your property, among the other materials necessary for chimney relining. They will straighten the chimney lining coil, measure it, and cut it to length, leaving enough to work with on the roof.

Next, the chimney technicians will insulate the chimney or flue liner. The Chimney Safety Institute of America (CSIA) and most fire codes require require that chimneys have a flue liner and that the liner must be insulated. Insulation keeps the liner warm and reduces creosote buildup. The CSIA regulation states a chimney liner must have a half-inch insulation.

Then, multi-purpose foil tape will be used to hold the insulation in place in the chimney liner before covering the entire coil with mesh. The mesh covering protects the insulation from getting torn as it’s being transferred down the chimney.

After, it’s time to install the flue liner. The job must be done in two parts: on the roof and then at the foot of the chimney. While on the roof, our chimney technicians will be mindful of power lines. A silicone seal will be applied to keep rain and insects out. At the top of the chimney, the cap and top plate will secure the chimney liner in place. At the bottom of the chimney, an adapter will be placed to secure the liner.

Know these general steps to install a chimney liner and trust Champion Chimneys to do the job right.
