During New England winters, temperatures frequently jump between below freezing and above freezing. This is especially prevalent in March, when the weather slowly begins transitioning between winter and spring. When you hear of pipes bursting in homes, it is often not only because of an increase in pressure due to ice freezing, but it is also often caused by the ice inside of the pipes thawing.

Freeze/thaw cycles have a similar effect on chimneys. The pores of the chimney can absorb water and then, when that water freezes, it expands and begins deteriorating the chimneys’ masonry.

How Freeze/Thaw Cycles Can Negatively Affect Chimneys

Freeze/thaw cycles can have a host of negative impacts on chimneys. Here are some of the issues that chimneys experience:

  • Chimney leaks
  • Masonry damage
  • Chimney crown damage
  • Firebox or damper rust

Ways that Best Chimney Services Combats Freeze/Thaw Cycles

Annual Chimney Inspections

A chimney inspection before the cold winter months will detect any chimney issues that you may have and give you the time to address those issues before your chimney is subject to the cold weather. We recommend hiring a CSIA certified chimney sweep to inspect your chimney, so that you are assured that the chimney company is skilled and ethical.

Chimney Masonry Work

Freeze/thaw cycles make existing masonry issues even worse. That’s why proactively getting chimney masonry work done can make a world of difference once winter comes around.

Waterproofing

One of the most effective chimney masonry services that will prepare your chimney for the winter is waterproofing. Since bricks absorb water like sponges, they need waterproofing to prevent water absorption. The product that Best Chimney puts on is 100% vapor permeable. This allows the water vapors to escape instead of being trapped. Check out our blog on the importance of waterproofing your chimney to learn more.
