5 Causes of Moisture in Your Home


Too much moisture in your home can be extremely harmful and lead to a wide variety of issues. Whether it’s mold, pests, or health issues, excess moisture and humidity is not a good thing. That’s why it’s important to regularly check areas of your home that may be susceptible to water. Here are a few potential causes of moisture problems:

1. Landscaping & Irrigation

One way that water could be entering your home is through your landscaping. If your home is not graded properly, water from either rain or irrigation could be running directly towards the walls and foundation. Ideally, your lawn should be graded so that the yard slopes away from the structure, thereby, directing water away from it. In addition, it’s important to keep landscaping that requires irrigation, at least five feet away from your home to limit run off.

2. Gutter & Downspouts

Similar to landscaping, gutters and downspouts can also direct water into your home. For instance, if gutters are clogged, then during a heavy rain fall, there could be a flood of water draining down the side of your home. This could also occur if sections of gutter are missing or damaged. Because of this, it’s important to regularly check your gutters and down spouts to ensure they are in proper working order.

3. Crawl Space

Another area of your home that can be a massive cause of moisture problems is your crawl space. If left unattended, your crawl space may be home to issues such as standing water, pests, or mold. If you do notice signs of high humidity and moisture, it’s important to take steps to control the humidity in the area. For instance, enclosing your crawl space and installing a dehumidifier will allow you to maintain a consistent humidity level and prevent many futureissues.

4. Basements

Just like crawl spaces, basements are also a common source of moisture. Since basements are situated underground, they are often more exposed to moisture than the other areas of your home. Furthermore, if your basement is not properly finished, it’s very easy for moisture to enter through the concrete block walls. Because of this, it’s a good idea to regularly inspect the basement for signs of moisture, such as mold. If you do notice moisture, take the steps to ensure the basement is properly finished. In addition, a dehumidifier is a useful tool to maintain a stable environment.

5. Equipment

Inside your home, there are also many items that may cause excess moisture. For example, an appliance, such as a dishwasher, could be leaking or a piece of equipment, such as a hot water heater could malfunction and flood the area. Plus, pipes throughout your home, could become problematic if they become damaged, and start dripping or leaking.
