All throughout the warmest parts of the year, your basement remains dry and inviting. However, when the cold weather rolls in and the snow starts to fall, your usually dry basement transforms into a damp, wet, and dank nightmare.
Thankfully, a wet basement in the winter only is usually fairly easy to diagnose with the help of a professional basement waterproofing technician. Take a look at some of the potential causes for a basement that seems to stay damp all winter long.
Your basement stays warmer than the ground outside.
The basement is far warmer than what it is outside because the ground temperature tends to stay fairly consistent so far down, and your basement likely reaches several feet down into the dirt. The heat in your basement rises, which means the heat radiates through basement walls closer to the upper parts of the ground that are likely laced with ice. As this radiated heat melts the ice, the moisture can seep into basement walls if the brick or concrete has grown porous or has cracked due to ground shifting. A basement waterproofing professional can help you avoid this seepage.
You have issues with ice damming and snow accumulation on the roof.
A snow-covered roof may look harmless, but it can actually lead to problems, even problems with water in your basement. Snow can melt and cause ridges of layered ice, which can bear down on your roof and gutters and lead to water leaking into all kinds of places that it normally would not. If an ice dam gets so large that it pushes the gutter away from the soffit, you could easily see moisture in your basement when the temperatures rise. While a basement waterproofing service can take measures to keep the water out, it is always best if these rooftop water issues are fixed so there is not such a big risk of prolonged problems.
Your basement walls are getting a lot of undue pressure from excess moisture.
Some places get foot after foot of snow when winter comes in. If this snow melts gradually, you may not see issues with a wet basement but that is normally not what happens. Most of the time, snow will melt pretty rapidly when a warm day hits. All this melted snow equates to an enormous amount of water in the soil. This excess water leads to heavy, moisture-laden soil that puts more pressure on basement walls. The moisture can easily be pushed through pores and tiny fissures in these situations. Most pros will use specially formulated sealants to seal off the pores and fissures so the problem will cease.
