Why Your Basement Leaks When It Rains (and How to Stop It)

Few things are more frustrating than finding water in your basement after a heavy rain. Whether it’s a small puddle or a full-blown flood, a leaking basement is a clear sign that water is finding its way into places it shouldn’t.

At A Better Choice, Inc., we specialize in diagnosing and fixing basement leaks for good. Here’s a breakdown of why your basement leaks when it rains—and more importantly—how you can stop it before it causes lasting damage to your home.

Common Causes of Basement Leaks During Rain

1. Poor Grading Around the Foundation

If the soil around your home slopes toward your foundation instead of away from it, rainwater will naturally pool near your basement walls—putting pressure on them and eventually finding its way inside.

2. Clogged or Damaged Gutters and Downspouts

Your gutters are supposed to channel rainwater away from the foundation. When they’re clogged or downspouts are too short, water ends up dumping directly at the base of your home, overwhelming your drainage system.

3. Cracks in the Foundation Walls or Floor

Even tiny cracks in foundation walls or basement floors can act as pathways for water. Over time, rainwater seeping through can lead to mold, structural issues, and ruined belongings.

4. Hydrostatic Pressure

After days of rain, the soil around your foundation becomes saturated. This builds up hydrostatic pressure, which pushes water through the foundation walls or floor—even if there are no visible cracks.

5. Window Wells That Collect Water

Basement windows can become a leak point if the wells around them aren’t draining properly. Water can build up and seep through the seams or frames.

6. Failing or Missing Drain Tile System

Homes are often built with a perimeter drainage system (also called a French drain or drain tile). If this system is damaged or missing, rainwater has nowhere to go—so it ends up in your basement.

How to Stop Your Basement from Leaking

1. Improve Yard Grading and Landscaping

Regrading the soil around your foundation can dramatically reduce water pooling. Make sure the ground slopes away from your home by at least 6 inches over 10 feet.

2. Clean and Extend Gutters and Downspouts

Clean gutters at least twice a year to remove debris.
Ensure downspouts discharge water 4–6 feet away from the foundation.
Consider installing downspout extensions or splash blocks.

3. Seal Foundation Cracks

Small cracks can be repaired with waterproof epoxy or sealant, but larger or growing cracks should be evaluated by a professional. This is where A Better Choice, Inc. comes in—our team can assess and repair foundation issues before they get worse.

4. Install or Repair a Drain Tile System

A functioning drain tile system relieves hydrostatic pressure by directing water into a sump pump or drain away from your home. If your home doesn’t have one, or if it’s no longer working, it may be time to invest in an upgrade.

5. Add Basement Waterproofing Solutions

Interior and exterior waterproofing methods offer long-term protection. Options include:

Interior drainage systems
Vapor barriers
Waterproof wall coatings
Sump pumps with battery backup

6. Install Proper Window Well Covers

These prevent water from collecting and seeping through basement windows. Make sure your window wells are clear of leaves and debris, too.
