Whether you’ve had a harsh winter already this year, or your chimney sustained damage in the past, it’s important to diagnose and repair the damage as soon as possible. Winter-damaged masonry can lead to more serious problems and costs in the future, so the sooner you call a professional, the better.

  • Chimney Leaks – When water enters the chimney system it can be catastrophic, leading to water damage in the chimney system itself, the fireplace or appliance, and also the rest of the home. The water may enter by a faulty chimney cap, damaged crown, spalling masonry, or dislodged flashing, but the water may travel through the home and form a leak elsewhere, many rooms away from the chimney. Expert tip: have your chimney system inspected annually and waterproofed after repairs so that the masonry is protected from water penetration.
  • Spalling Masonry – When the masonry becomes cracked, crumbles, and bricks and mortar pieces begin to fall, this is called spalling. Spalling masonry is extremely dangerous for the chimney and can cause bricks to fall onto and damage the roof and landscaping below as it becomes more serious. Expert tip: have your masonry waterproofed with a deep-penetrating water repellent by Billy Sweet Chimney Sweep to prevent water masonry damage. Schedule a professional to repair your masonry through a process called tuckpointing.
  • Crown Damage – Winter weather can wreak havoc on a chimney crown that is old, poorly maintained, and improperly constructed. If a crown is too thin, flat, or made of the wrong materials, water can penetrate it during winter months and then freeze, causing more damage through what’s called the freeze-thaw cycle. Expert tip: ask your chimney professional specific questions about crown construction. It should be constructed with the right materials and design for a lasting crown.
  • Dislodged Flashing – Harsh winter temperatures and storms can lead to dislodged flashing. Since the intersection of the chimney and roof is the most vulnerable part of your entire chimney system, dislodged flashing can have serious hazardous results. Expert tip: look at your flashing after strong winds or prolonged ice or snow exposure. Exposed nails, shifted metal, and missing flashing is reason to call a professional right away.

The Freeze-Thaw Cycle

Winter is the most common time for chimney damage that has nothing to do with the fire. Yes, you’re using your fireplace more, but winter damage is caused by outside forces—temperatures, pressures, precipitation, animals, and more. The worst thing that can happen to your chimney during winter months is water penetration. Because masonry is porous by nature, allowing water to penetrate beyond the surface, freezing temperatures can be devastating as the moisture trapped in the masonry freezes and thaws. Water fills the gaps and voids in the masonry, then freezes as temperatures fall. The water expands as it freezes, breaking apart the masonry. Then when a fire is lit or the sun warms the chimney again the water thaws and moves further into the damaged masonry. This process repeats all winter long, causing serious damage in a short time. If this damage isn’t repaired and the chimney waterproofed, the chimney may require a serious repair or rebuild. If the damage remains throughout the spring months, water will have a direct route into the chimney system to make more damage.
