Control Water in the Basement 

Your basement is likely to get wet or damp at different times of the year, but more so during spring and summer. Summer months in Charlotte, NC, are hot and humid, while spring is mostly wet. Rainwater can seep in through cracks and moisture can also condense on your basement walls. But these aren’t the only sources of moisture. 

No matter the source, you should take preventive measures, including waterproofing your basement. But first things first — get to know what causes basement moisture before applying any fix.

What Makes the Basement Wet? 

Moisture-laden air from the outside can make your dry basement damp. Basement venting, especially dryer vents, is the other culprit. Foundation cracks can also encourage water seepage. But that’s not all. 

Oversaturated soils can instigate wetness by allowing water to go through our porous drywall. 

Be worried if the moisture levels go above 60%, as this is when most problems manifest. Signs that your basement has water or moisture issues include: 

  • Musty odors 
  • Condensation 
  • Mold spots 
  • Peeling wall paint 
  • Warping floors 

Want to Keep the Basement Dry? 

Try out these solutions. 

1. Grade Your Home 

Make sure the earth around your home slopes gently outward and not inward. Otherwise, water will flow back and around or into your home whenever it rains. This water can penetrate foundation cracks and collect on your basement floor. Grading prevents backflows and wet basements. 

2. Fix Gutters and Downspouts 

Like homeowners in many Charlotte, NC, neighborhoods, you probably check the roof once a year or whenever there’s a leak. Summer has its fair share of rains. The ground quickly heats up and loses water through evaporation. When this air rises, it condenses, then falls back to the earth as rain. Such water can easily overwhelm the roof and your gutters if the latter is loose or clogged. Not only will water flow through the sides but collect in your foundation. You can guess where most of it will end up. Don’t forget to angle the downspouts as well. It’s pointless to have functional gutters but badly angled downspouts, as water won’t go as far out as you want it. You might also consider placing your downspout lines in the ground, as well. 

3. Waterproof the Basement 

While summer rains won’t threaten your basement, they can still hurt it. Make sure you install an interior drainage system and keep it clog-free and in good shape. The same goes for the sump pump. Together, these systems move any water that gets into the basement outside. The BasementGutter™ interior drainage system intercepts the water while the sump pump ejects it so it doesn’t cause flooding. 

4. Dehumidification 

A low-lying area like the basement can accumulate moisture during the summer months. Air leaks, open windows and other factors can raise the levels of humidity. The excess moisture can cause wall paint to peel off and the basement floors to warp. You can avoid these and other problems by installing a dehumidifier. It will dry out the air and create a dry, comfortable basement. Get an energy-efficient dehumidifier with a self-draining mechanism so you won’t end up emptying buckets of water every day. 

Your local basement repair contractor can help you with the sizing and installation. 

5. Insulate Your Basement 

Air exchange can disrupt internal conditions. You can maintain the coolness or warmth of the basement by insulating the basement walls with an impervious material. Polyurethane foam is a good option. It’s energy-efficient and creates an effective air barrier. Some types of foam expand and fill all nooks and crannies in your basement. 

We wouldn’t advise you to apply wall paints, oil, or water, as a waterproofing solution, as they will eventually peel off. Remember to insulate your cold water pipes to prevent sweating. 

6. Keep the Windows Closed 

Leaving your basement windows open or the door ajar can worsen the moisture condition in your basement. Humidity levels will increase and this will trigger moisture-related problems. Pollutants may also get in and contaminate the air inside your home. You’re better off closing them.
