Healing your chimney one appointment at a time
Prevent potential health and safety issues with your aging chimney. Chimneys with a wood burning fireplace are lined with terracotta clay flue tiles. These tiles are susceptible to deterioration or cracking. Your chimney can experience wear and tear from weather elements, water damage, or by act of nature. Weathering by water can cause washed out tile joints between the tiles in the chimney. Damage from acts of nature can range anywhere from lighting strikes, chimney fires, or rapid heating of the liner (done by burning paper). If your chimney is in need of repair or relining, our team is ready to help.
Repair your weathered chimney with our chimney relining services. We can replace your lining with stainless steel or our heat shield product. If your chimney needs a repair, our team of experts is ready to help.
Current Minnesota Residential Chimney Code (codes listed in the 2018 IRC or NFPA 211 may not apply to MN current code standards)
Stainless steel chimney liners are UL 1777 listed as a replacement lining system of a solid fuel burning appliance. They have a lifetime warranty and hold up to the corrosive elements found in creosote. We insulate the liner with a "cerwool" blanket to promote better drafting and more efficient heating. Replacing a lining system with terracotta clay tiles is still an option, however it is a less cost effective option due to the labor required to complete this type of repair.
HeatShield can be a more affordable way to repair your chimney's lining system. HeatShield is a sealant that can withstand temperatures in excess of 2900 degrees Fahrenheit. This material can restore a chimney liner by filling gaps or resurfacing any cracks or spalling within the terracotta clay tiles. It is installed by using a custom "foam cut" applicator which helps to smooth the sealant into the gaps or damaged tiles. HeatShield comes with a 20 year warranty allowing you to enjoy your fireplace for the length of your home ownership.
We begin with an accurate measurement of the fireplace opening to properly size the liner. This will help ensure a proper draft when using the fireplace. A liner too small can cause smoke issues. We begin the installation by shattering and the removal of all the existing clay tiles. We then insulate the stainless steel liner and insert it into the chimney. Once inserted we secure and seal the liner in place by parging the bottom with high temp refractory cement such as Chamber Tech 2000. For cosmetic reasons, we terminate the liner at the top with a clay tile. Once completed, we install a stainless steel chimney cap to prevent animals, rain, or snow from entering the chimney.
