During the winter, our fireplaces work hard to keep us warm and comfortable no matter what the weather outside is like. Unfortunately, the same snow and ice that our homes protect us from can have a serious negative impact on your chimney system.
As temperatures begin to rise again and spring is finally on the horizon, now is a great time to have your chimney inspected for signs of damage from this winter’s snow and ice. Even if your chimney has been damaged, identifying and repairing the damage as soon as possible can minimize the effects of the deterioration and keep your chimney in peak condition.
How winter weather damages your chimney
While bricks are mortar are tough building materials that are made to stand up against the elements, many homeowners do not realize that bricks are actually permeable. This means that small amounts of water from rain, ice, and snow can be absorbed by the masonry. And while undamaged bricks may only absorb a droplet or two at any time, masonry that has cracks, holes, or is otherwise deteriorating is at significantly higher risk of water damage.
One of the most common ways masonry is damaged during the winter is by the freeze thaw process. As outside temperatures drop, the water absorbed into the brick freezes and expands; as the water melts, it leaves behind a larger hole or crack through which even more water is absorbed. The freeze thaw process can cause bricks to crack and spall in as little as one year depending on the level of damage.
Preventing snow and ice damage
Living in Minnesota, it is inevitable that our chimneys will be exposed to snow and ice every winter. Because of this, it is important to have preventative maintenance done to help protect your chimney against winter water damage.
Having your chimney professionally waterproofed is often the most effective way to prevent water damage all year long from ice, snow, and rain. Our professional-grade sealants produced by SaverSystems are specifically designed for use on masonry; these permeable barriers allow gas and smoke to pass through the bricks and mortar safely while still keeping water out. Even if your chimney is already showing signs of masonry damage such as cracking or spalling, applying a waterproof sealant can help slow the progression of damage and protect the rest of your chimney.
The importance of a chimney inspection
Whether you use your fireplace every day during the winter or simply use it for the occasional special occasion, an annual chimney inspection is one of the most important things you can do for your chimney in terms of preventative maintenance. Chimney inspections allow problems or areas of deterioration to be identified early, long before they turn into serious damage. This kind of preventative maintenance not only protects your chimney, but can also help save you money; a chimney inspection and minor repairs is significantly less expensive than major fireplace or chimney reconstruction.
