Should You Invest in a Basement Dehumidifier After a Flood?

Dehumidifiers help remove moisture after the basement floods. But just how well do they bolster your waterproofing efforts?

Flooding in the basement is many homeowners’ worst nightmare. It fosters different problems, including mold and mildew, damage to your belongings, and structural damage, among others. Depending on the severity of the flooding, you may have to pay thousands of dollars for repairs. 

This is where a basement dehumidifier comes in handy. This appliance helps regulate moisture levels by drawing moisture from the air. Dehumidification can reduce basement humidity levels by 50%. But is it worth the effort for your basement? What role does it play in the aftermath of flooding?

Benefits of a Basement Dehumidifier 

Here are just some of the ways your basement can benefit from having a dehumidifier installed: 

Removes Water Fast 

If flood water stays in the basement for too long, you’ll be wading through water to salvage personal items and valuables. A sump pump gets rid of the surface water. And while that is a step in the right direction, you still need a dehumidifier to reduce the moisture levels. 

Prevents Allergens 

From mold and mildew to dust mites and bacteria, moist air creates the perfect environment for the growth of allergens. These lead to sneezing, coughing, musty odors, itchy eyes, and wheezing. Using a dehumidifier makes the basement inhospitable to allergens and protects your family’s respiratory health, even in the event of a flood. 

Reduces Energy Costs 

Flooding leads to excess moisture in the air, forcing the AC to work harder to keep the air cool. The result is higher utility bills and eventual damage to the AC. Invest in a dehumidifier to avoid higher energy costs. 

Safeguards Against Water Damage 

Moisture can cause serious damage to your home if left to accumulate—peeling wallpaper, decaying wooden objects, split floors, and cracked ceilings, among others. A dehumidifier can protect your basement and the valuables inside. You won’t have to worry about expensive repairs if dealt with immediately. 

Improves Air Quality 

While an air purifier cleanses the air in your home, a dehumidifier does a much better job as it dries out the air and filters harmful particles from the air. You and your loved ones will breathe clean air. 

More Tips to Keep Your Basement Dry 

You can’t depend solely on the dehumidifier to protect your basement against flooding and water. The best it’ll do is to prevent moisture buildup and mold development. To bolster your basement waterproofing, consider the following measures as well. 

  • Install a gutter-and-downspout system. This is the first line of defense against basement flooding. What this system does is collect water and drain it away from the roof so it won’t end up in the foundation. If you already have one in place, clear any debris in the gutters and install a leaf guard to keep dry leaves out. Also make sure the gutters and downspouts are properly connected, as well as angled down and away from your foundation to properly drain water. 
  • Install an interior drainage system. An interior drainage system is one of your best resources against leaks and seepage that threatens the basement. It works even better when paired with a sump pump. 
  • Install a sump pump. A sump pump is your best protection against floodwater. This device pumps water that pools on the floor or is collected by the interior drainage system away from the house via discharge pipes. 
  • Grade your yard. The slope of the ground around the house has a bearing on your basement dryness. Make sure it slopes by at least six inches for every 10 feet. 
  • Seal the cracks. Always inspect the basement walls and foundation for cracks, and seal any that you find. Ask your local waterproofing expert to assess the cracks and recommend the best fix. 
  • Fix plumbing issues. It’s not always easy to diagnose leaks on your basement walls. And even then, many homeowners mistake them for waterproofing issues. Inspect the water supply lines and repair leaky pipes quickly. 
  • Seal the windows. Drafty windows could be a potential source of leaks. Look for warped sills and reseal the windows. Consider installing window well covers, as they keep water out and ensure the basement stays bright. 

When it comes to basement flooding, a dehumidifier is a great addition that will prevent water damage. Unfortunately, it’s not the end-all solution to basement waterproofing. It’s important to invest in other waterproofing measures to ensure a clean, dry, and mold-free basement.
