Even though Nashvillians are fortunate to have somewhat moderate winters, we still get a few snow and ice storms from time to time. We can also have extended periods of freezing temperatures during the winter. When the Nashville area suffers from brutally cold weather, masonry chimneys also suffer. The harsh winter weather we do get can really take a toll on the bricks and mortar of your chimney, and each spring Ashbusters gets many calls regarding leaky chimneys that are the result of winter weather damage. Spring definitely is the season for chimney leaks, and you can trust our Chimney Safety Institute of America (CSIA)-certified chimney technicians to find the leaks and repair them. We can also protect your chimney with a few preventive measures to keep your chimney free from leaks in the future. We would like to tell you how winter weather damages your chimney and how we can help you by repairing and preventing this damage.
Why does winter weather cause chimney leaks to occur?
The CSIA was not joking when they said water is the biggest enemy of masonry chimneys. One of the worst ways water can damage your chimney is spalling damage, which happens in the winter. The bricks and mortar of your chimney are naturally porous and absorb water. When the temperature drops below 32 degrees Fahrenheit, the water trapped inside your bricks and mortar freezes and expands. When the weather warms back up, this water thaws and causes the bricks and mortar to crack and break apart. This creates gaps and holes in the structure of your chimney that allow water to easily enter into your chimney. Spalling damage can happen numerous times in the winter, and if left unrepaired, your chimney could become so weak that it collapses.
How can Ashbusters repair and prevent this damage?
Our experienced masons have the skills to replace any missing bricks and mortar joints to fill in the gaps and holes in your chimney. We use techniques like tuckpointing, which keeps our repair work from looking like a patch-up job. We will also inspect your chimney to look for any other possible leak sources and repair any we find.
To prevent spalling damage from occurring next winter, we offer several different water penetration preventive services. We sell and install chimney caps that keep water (and birds, squirrels, and raccoons) out of your chimney. We also construct, install, and repair customized flashing systems that protect the area where your chimney meets the roof. Consisting of metal sheets wrapped around the chimney at the roof, a flashing system provides a watertight seal of your chimney that keeps water from entering at the roof. The best preventive measure you can take against spalling damage is to have your chimney waterproofed. We will apply a waterproofing formula that creates a barrier against water penetration of the bricks and mortar of your chimney. This will keep water from getting absorbed into the bricks and mortar, so there will be no freezing and thawing going on inside these masonry materials.
If you suspect your chimney has a leak, you should get it repaired as soon as possible. Contact us at Ashbusters to schedule a chimney leak inspection today.
