Recent Bad Weather Could Damage Your Chimney

It’s been a winter of record-breaking weather in the Northeast United States. The Weather Channel is reporting some of the worst weather in years, and New York City has experienced some of the coldest temperatures in ten years. With the month of March expected to come in like a lion, many homeowners are concerned about the potential damage all this weather could be causing.

The Stack Effect

The cold weather could be affecting your heating bill, but beyond that harsh winter weather can also affect your chimney. During something called The Stack Effect, the cold air from the outside of your home battles with the warm air inside your home. When cold air is forced down your chimney and into your home (because of chimney leaks or a poorly capped chimney) this can force a back draft in your fireplace making lighting a fire almost impossible.

The Moisture Effect

Another major culprit of chimney damage is moisture. When there is an excessive amount of snow and/or ice like we’ve been experiencing in the Northeastern United States, this precipitation can make its way into your chimney. Not only can this make it very difficult to light a fire in your fireplace or stove difficult but it can also create a build-up of creosote. Creosote is a potentially harmful chemical build-up inside a chimney that occurs when a fire isn’t burning hot enough.

How You Can Protect Your Chimney From Winter Weather

Moisture and cold air are two of the main culprits causing chimney damage during the long and cold winter months. Luckily, there are certain precautions you can take to make sure you address chimney damage before it becomes a major problem:

After heavy snowfall, inspect the exterior of your chimney for any noticeable damage.
Inspect the interior of your home for water damage or peeling paint/wallpaper around your chimney or fireplace. This could signify a leak or other chimney damage.

Perhaps the best thing you can do to protect your chimney happens before winter sets in. Hire a professional chimney sweeping company like Chief Chimney Services in Suffolk County to inspect and sweep your chimney before the winter months. Your chimney sweeping company will make sure there is no major damage to your chimney and will keep it clean. Beyond that, your chimney sweeping company will:

Recommend a top-sealing damper
Re-line your chimney
Recommend and install a chimney cap

These easy add-ons can protect your chimney from harsh winter elements like cold air and moisture. After all, having an airtight chimney is the best way to protect against bad winter weather.

This winter has been one of the record books. Between the frigid temperature and immense amount of snow many homeowners can’t wait for spring to arrive. While you’re waiting out the storm, be sure to hire a reputable, professional chimney sweeping company to help you maintain your chimney and keep it in great working order. An airtight chimney will heat your home, as well as keep your loved ones safe while winter continues to rear its ugly head.

Changing Temperatures Can Seriously Damage Your Chimney

If any part of your home can withstand the notoriously harsh New York winters, it would be the chimney. Made of tough brick or stone, it has most likely seen decades or even centuries of unforgiving temperatures. While the chimney is particular strong and durable, it does have weaknesses and that includes dramatic changes in weather.

Chimney damage due to temperature changes starts with the presence of moisture in the structure. Aside from stone, all materials used to create a masonry chimney are porous and sensitive to contact with water. Even stone chimneys need mortar to bond the stones together, so they do not escape the dangers of water. When water hits materials like mortar or brick, the porous materials absorb the water like a sponge. While this does not have immediate repercussions, it will eventually cause damage.

During the bitterly cold winters on Long Island, every outside structure is subject to the freeze and thaw cycle. This includes your chimney. Now that the porous materials on the chimney contain water, the freeze and thaw cycle can damage the structure. The water inside the brick or mortar expands and contracts in freezing cold temperatures and this continuous movement weakens the brick and mortar.

Signs of damage due to changing temperature include cracks in the mortar, loose bricks or stones, missing bricks or stones or a listing structure. Without the proper attention and maintenance, a water and temperature damaged masonry chimney could collapse, which means serious costs.

You can protect your chimney from this type of deterioration in a couple different ways. One way to do this is to have a chimney service apply water repellent to the outside of the chimney. Using a water repellent instead of a sealant is crucial, because the repellent allows water vapor trapped in the masonry to escape, while it discourages water entry. A sealant will keep any moisture trapped and the damage will happen anyway.

Another way to protect your chimney is to have a chimney cap installed. A chimney cap is a small, simple contraption that covers the top of your chimney. Usually made of copper or stainless steel, chimney caps prevent water from freely entering the inside of the chimney. This can help prevent water damage to your masonry and water damage to other areas such as the flue, damper, and the inside of your home. In addition to keeping water out of the chimney, chimney caps also prevent animals from nesting in the flue and keeps live embers from escaping to create a fire hazard.

Both the application of a water repellent and the installation of a chimney cap should be performed by a licensed professional. Chimney caps sold by big box hardware stores are generally low quality and a chimney service can provide you with a properly fitting, high quality chimney cap that will last years longer. Also, both services pose serious danger to your safety, so consider leaving them to the experts.
