Humidity in Basement

Ever notice how some basements feel like a sticky summer day? While it might be common, it’s not good for your home. Too much dampness in the basement can foster mold growth, invite pests, and even harm your home’s foundation. If these signs sound familiar, you should take action. 

With decades of experience in basement waterproofing and humidity control, JES Foundation Repair has the solutions to tackle basement moisture and humidity. This page will help you understand why your basement might feel damp and how experts can help. 

What Is Basement Humidity? 

Humidity is the measure of water vapor in the air. Specifically, relative humidity gauges how much moisture there is in the air compared to the most it can hold at a certain temperature. 

When the relative humidity in basements consistently surpasses 55-60%, it creates the ideal environment for problems such as: 

Neglecting humidity can result in negative consequences for both your home’s stability and the well-being of your family. To tackle basement humidity, it’s essential to recognize its root causes and apply strategies to manage the sources of moisture. 

What Causes Basement Humidity? 

Several elements lead to increased humidity and moisture in basements, such as: 

  • 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. Open basement windows and wall cracks also allow high outdoor humidity levels to condense on cool basement surfaces. 
  • Inadequate Insulation: Many basements lacking adequate insulation worsen the problem by allowing warm, moist air to come into contact with cooler basement walls, creating condensation.  
  • Everyday Activities: Baths, laundry, and other household activities add moisture to indoor air. 

Tackling these problems directly at their origin is vital for successfully controlling humidity. 

Can You Fix Basement Humidity? 

Yes! With the appropriate waterproofing solutions, basement humidity can be permanently addressed. To fully eradicate excess moisture, dealing with the fundamental causes is essential. While quick solutions like dehumidifiers purchased from stores or moisture absorbers offer temporary relief, they don’t address the root issues. 

We advocate for our comprehensive basement waterproofing system, designed to fully secure and stabilize your home. Implementing these solutions results in a basement that’s cleaner, healthier, and more functional. 

How JES Foundation Repair Addresses Basement Humidity: 

Effectively controlling basement humidity involves these key steps: 

  • Inspection: We thoroughly assess your home and use tools like moisture meters and hygrometers. This allows us to pinpoint where water is entering and recommend appropriate solutions. 
  • Interior Drainage: Our perimeter interior drains catch leaking water and direct it to a sump pump, keeping it away from your basement. 
  • Sump Pump: Water collected by the interior drains is directed to a sump pump, which actively removes the water from your basement. 
  • Wall Vapor Barrier: A thick vapor barrier prevents moisture penetration through basement walls. 
  • Dehumidifier: Our powerful, energy-efficient dehumidifier controls moisture levels and improves indoor air quality. 

JES Foundation Repair offers a proprietary line of products, each personalized to solve your unique problems, making our solutions far more effective than those you’ll find at a mainstream retail store. These solutions are protected by comprehensive, long-term, transferrable, nationally backed warranties. 

Why Address Humidity in Your Basement Now 

It’s crucial to tackle basement humidity promptly for the following reasons: 

  • Health Concerns: Elevated humidity fosters mold growth, which can harm health and degrade surfaces. 
  • Pest Problems: Moist conditions lure pests such as spiders, termites, cockroaches, and other critters, while also promoting musty smells. 
  • Enhanced Air Quality: Ridding your basement of moisture boosts the air quality in your home, warding off respiratory challenges. 
  • Structural Damage: Persistent dampness can cause foundation and structural elements to twist, decay, and deteriorate over the years. 
  • Energy Expenses: Moist basements consume more energy for heating or cooling, inflating your utility bills. 

By working with our team of basement waterproofing experts at JES, you can ensure a consistently dry, cozy, and functional basement area. Our proprietary, tailor-made solutions are designed to provide permanent relief from basement humidity.
