Unwanted Guests: How Moisture Can Enter Your Home

Moisture is an inevitable part of our environment, but its presence within our homes can lead to a variety of problems. Excess moisture can not only create an uncomfortable living environment but also promote the growth of mold, damage your belongings, and trigger allergies. Understanding the ways in which moisture can enter your home is the first step towards creating a healthy and comfortable living space.   

One common source of moisture intrusion is through the foundation. Damp soil surrounding your basement or crawlspace can allow moisture to seep into your home. This is especially prevalent in areas with high water tables or poor drainage.  In basements with concrete slabs, a properly installed under slab vapor barrier can help prevent moisture from migrating upwards through the concrete.   

Malfunctioning plumbing is another major culprit for moisture problems. Leaky pipes, faucets, or drains can introduce significant amounts of water into your home. Even minor leaks, if left unattended, can lead to mold growth and structural damage. It's crucial to regularly inspect your plumbing for any signs of leakage and address any issues promptly.   

Everyday activities within your home contribute to moisture levels as well. Cooking, showering, and even drying clothes indoors can release significant amounts of water vapor into the air. Proper ventilation is key in these situations.  Turning on exhaust fans in kitchens and bathrooms during and after use helps expel moisture-laden air.   

Humidifiers, intended to add moisture to dry air during winter months, can also contribute to moisture problems if not used properly.  Overuse of a humidifier can lead to excessive indoor humidity, creating a breeding ground for mold and mildew.  Using a hygrometer to monitor indoor humidity levels and maintaining a relative humidity level between 30% and 50% is recommended.   

By understanding the various ways moisture can enter your home and taking preventive measures, you can create a healthy and comfortable living environment.  Regular inspection and maintenance, proper ventilation, and addressing moisture issues promptly will help keep unwanted guests like mold and mildew at bay.
