We want you to be prepared, so please read on.

What Causes Basements to Flood in Lake County?

Knowing how a basement can flood makes it easier to prevent future problems. These are the most common causes of basement flooding in Lake County.

  • Severe Weather Events – Torrential rains or heavy snow melts fill the basement with water.
  • Plumbing Failures – Frozen burst pipes or broken plumbing lines flood the area.
  • Clogged Gutters – Water from overflowing gutters seeps behind exterior walls and into the basement.
  • Broken Sump Pump – A clogged drain line or faulty components prevent proper pump operation.
  • Appliance Problems – A broken washing machine or water heater floods the basement.
  • Foundation Ponding – Bad drainage results in standing water around the foundation that seeps into the basement.
  • Cracked Basement Walls Cracks in basement walls widen and rupture, filling the downstairs with groundwater.

It’s important to understand that homeowners insurance covers most basement flooding, but it doesn’t cover the damage caused by a natural event. 

If you don’t already have flood insurance, talk to your agent about purchasing coverage from the National Flood Insurance Program.

Why Is Basement Flooding Serious?

A basement full of water is more than a huge cleanup project. Pumping out the water only addresses the immediate situation. 

Porous basement walls, poor ventilation and high humidity levels create invisible problems.

For example, residual moisture quickly spreads through porous materials. The dampness ruins drywall and rots wood. 

Mold growing in water-damaged materials migrates into walls and floors upstairs and contaminates HVAC vents and ductwork.

Without proper mitigation, water damage from a flooded basement can weaken your home’s foundation, compromise its structural integrity and impact indoor air quality.

What To Do If Your Basement Floods: 7 Important Steps

Before you try to take care of flooding in the basement, think about the hazards of working in standing water. 

Turn off the basement’s electricity at the breaker box. If you can’t do so safely, call a licensed electrician.

Identify the water source, address the problem, and put on non-slip work boots before heading downstairs.

1. Assess the Situation

Take a look at how deep the water is in your basement. The cleanup work may require renting water extraction equipment, heavy-duty fans and a large dehumidifier.

Power Tip: If the weather cooperates, open basement windows so that fresh air can circulate through the area.

2. Call Your Insurance Company

Most homeowners insurance policies cover basement flooding caused by bad plumbing and appliance breakdowns. Talk to your agent, and schedule an adjuster’s visit as soon as possible. 

Power Tip: If cleanup appears to be more than you can handle, ask your insurance agent to recommend a restoration company that specializes in water-damage emergencies.

3. Clean Up and Dry Out

Remove standing water from the basement with a wet vac or your rental equipment. 

Set up fans in opposite corners to circulate a steady flow of cross-ventilating air. Plan on continually running the fans and dehumidifier for several days.

4. Document the Damage

Take pictures of the basement so that you can document the damages caused by the flooding. Include photos of stored belongings, appliances and any other water-damaged items. Your digital records will help support your insurance claim.

Power Tip: Don’t throw away things ruined by the basement flooding. You want the adjuster to see the full extent of your losses.

5. Tear Out and Prep

Once the adjuster has made his or her inspection, tear out ruined materials, such as drywall, vinyl flooring or carpeting. Prep these areas for reconstruction or replacement.

6. Scrub and Disinfect

Next, scrub and disinfect all basement surfaces affected by the flooding, including floors and walls. As you work, be on the lookout for signs of mold that may need extra attention.

7. Rebuild, Repair and Replace

Finish by rebuilding torn-out areas in the basement and replacing water-damaged flooring. Wooden basement stairs may need repair. Continue to run the fans while you complete the work. The entire area must dry completely, so be patient.

How to Know When to Call Water Damage Professionals
