Basement Water Damage - Complete Basement Systems™


Few issues strike fear into the hearts of homeowners more than flooded basements. If water infiltrates your home after heavy rain, it can damage your possessions, lead to mold or mildew that endangers the health of you and your family, and cause all sorts of stress. It’s best to prevent such a problem from happening than to have to respond to the problem after it has happened -- and you can do this by creating a basement flooding protection plan.


Here’s a look at some of the things you can do to stop your basement from flooding in heavy rain.


Ensure Your Lawn is Graded Properly

If the lawn around your residence grades or slopes toward your home rather than away from it, you're vulnerable to basement flooding. Whenever it rains, the water must go someplace. If your land is slopped the right way, the water will run away from the foundation of your residence and toward the street. The only way you can ascertain if your lawn is graded properly, you need to survey your property. So physically take walk around your home to see if your yard grades away from your home. If it does not, then you'll need to take action sooner rather than later. You can either do the work yourself or hire professionals who can do the landscaping work you need. 

Get a Sump Pump

A basement flooding protection plan should also include the installation of a sump pump in your basement. If you’re not sure what a sump pump is, it is a piece of equipment that diverts water from your basement to someplace outside of your residence.


The sump pump resides inside a hole created in your basement floor, and it includes valves that detect any increase in water pressure or water levels. When problems are detected, the sump pump automatically removes water from your basement through what is called a discharge line. You’ll want to get a licensed plumber to help you with your sump pump project

Emergency Backup Power

While you’re thinking about a sump pump for your basement, you should also consider emergency power backup options. This will ensure your sump pump continues to work even if there’s a power outage -- something that can happen during especially inclement weather. 

Mind Your Downspouts

When working on your basement flooding protection plan, you also need to be mindful of the placement of your downspouts. You’ll want to ensure that they extend away from the walls of your home so that water doesn’t settle near the foundation. This is something you can do by getting downspout extensions from a hardware shop, and it won’t cost an arm and a leg to do so.

Keep Gutters Clean

If your gutters are cluttered with leaves, debris, and other things, you’ll face an elevated risk of your basement flooding in the event of heavy rain. The problem is that water that can’t properly drain from the gutters will overflow and be deposited close to your walls. When there’s a lot of rainwater pooled around the foundation of your home, you are asking for problems. Technically, you should clean out your gutters at least once a year. Twice per year -- in the spring and in the fall -- is better. By cleaning out your gutters, you will reduce the odds of your basement flooding.


Following these steps will help you to keep your basement from flooding in heavy rain. While many of these recommendations can be done by a homeowner with good DIY skills, you’ll want to get a licensed plumber to help you with your sump pump needs. A quality sump pump is a must for any basement flooding protection strategy, so it pays to call in the professionals if you want your sump pump to protect your home in the event of heavy rain.
