Flood damage to homes in Twin Falls, Idaho, and other communities in the greater Magic Valley area can occur quite quickly. Flooding can result from several reasons, many of which are smaller issues homeowners aren’t always aware of. For example, everything from seasonal runoff to plumbing failures can cause water damage in homes. Understanding the common causes of home flooding can enable you to be proactive and take all the necessary preventative steps.
Rapid snowmelt represents one of the most common causes of seasonal water damage issues in Twin Falls, ID, and the Magic Valley area. As snow accumulates during the winter season, it sets the stage for significant runoff in the spring. When temperatures rise, snowmelt can cause the ground around your home’s foundation to become saturated and may also overwhelm your drainage system. When combined with spring rains, this process often has disastrous effects, leading to the overflow of creeks, streams, and irrigation canals.
There are a few red flags that could indicate you’re dealing with excessive groundwater that could be a flood damage cause. Water seeping through cracks in your home’s foundation is one to watch out for, as is basement flooding. It’s also important to check for moisture pooling around the perimeter of your property.
Heavy rains are another cause of home flooding stemming from common weather patterns that regularly occur throughout the region. A sudden storm can bring rains that are simply too much for gutters and storm drains to handle all at once, resulting in overflows or dangerous leaks. If this rainfall follows a dry period, it can be especially problematic. That’s because dry, compacted soil is slow to absorb moisture, meaning water will pool on top of it and flow directly to low-lying spaces such as your basement.
Flooding doesn’t always start outside the home. Many cases of home flooding actually begin with a plumbing issue. In some instances, though, Mother Nature still plays a role. During an especially harsh winter, poorly insulated pipes can freeze and then burst. Aging pipes with corroded sections or leaks are especially vulnerable.
Even what seems like a tiny leak can expel a significant amount of water over time if left unchecked. That’s why it’s also necessary to inspect plumbing pipes and any hoses connected to your water heater, washing machine, dishwasher, and refrigerator ice maker regularly to ensure everything is in working order.
Sewage backups can additionally lead to residential flooding. This happens when wastewater is blocked due to an overloaded sewer system or a clog. Flooding in this case can be particularly dangerous, with contaminated water flooding out of drains, sinks, and toilets and into your living space.
Common sewage backup causes include:
