Humidity in Basement

Stepping into a damp basement can feel like walking into a misty forest. This shouldn’t be the norm for your home. 

Too much humidity in the basement can invite mold, pests, weaken your home’s structure, and bring other challenges. These are warning signs that shouldn’t be ignored. 

Tar Heel Basement Systems, specializing in basement waterproofing and humidity control, offers tested solutions to rid your basement of excess moisture for good. 

This page will guide you through common issues with basement humidity and how our expert team tackles them, helping you make the right choice for your home. 

What Is Basement Humidity? 

Humidity is basically how much water is in the air. When we talk about relative humidity, it’s comparing the water in the air to how much it could hold at that temperature. 

It’s an issue if your basement stays at humidity levels above 55-60% for too long. This can lead to problems like: 

Ignoring this can lead to bigger problems that might affect your home and your family’s health. Figuring out why it’s happening is a key element in finding ways to stop it. 

Why Is My Basement So Humid? 

Several things can make your basement damp: 

  • Water Intrusion: Water can leak inside through cracks in walls, floors, joints, and openings around pipes, wires, and windows. 
  • Water Seepage: Groundwater easily seeps through porous concrete walls or floors. 
  • Internal Leaks: Plumbing pipes can burst, and appliances like water heaters and washers can leak inside the basement. 
  • Exterior Drainage: Damaged gutters and improper landscape grading cause rainwater and snowmelt runoff to collect around the foundation. 
  • Outdoor Humidity and Poor Ventilation: Many basements lack proper ventilation and air circulation. Basement windows left open and wall cracks also allow high outdoor humidity levels to condense on cool basement surfaces. 
  • Inadequate Insulation: The issue is exacerbated in numerous basements that lack proper insulation, as it permits warm, humid air to meet cooler basement surfaces, leading to condensation. 
  • Household Activities: Tasks like bathing, doing laundry, and other domestic chores introduce additional moisture to the indoor environment. 

Understanding and fixing these issues is key to a dry basement. 

Can You Fix Basement Humidity? 

Yes, basement humidity can be permanently addressed with the appropriate waterproofing methods. To fully eradicate excess moisture, it’s essential to address the underlying causes. Simple solutions like off-the-shelf dehumidifiers and moisture catchers provide temporary humidity relief but don’t tackle the root issues. 

We suggest our all-encompassing basement waterproofing system to thoroughly waterproof and fortify your home. These methods result in a cleaner, healthier, and more functional basement space.
