Basement Flooding and Sewer Backups in Downers Grove: What to Do First

For many Downers Grove homeowners, the basement is where water trouble shows up first. A heavy summer storm overwhelms the sewer system, a sump pump fails during a power outage, or melting snow finds its way through a foundation crack. Within minutes, a finished basement can go from family room to emergency.

As a restoration company headquartered right here in Downers Grove, Guardian Property Rescue responds to these calls all year. Here's what to do first, what to avoid, and how to get your home dry and safe again.

1. Figure Out What Kind of Water You're Dealing With

Not all water is the same. Clean water from a supply line is the least hazardous. Water that comes up through a floor drain, toilet or sewer line, or floodwater that entered from outside, should be treated as contaminated because it can carry bacteria and other harmful material.

If you see or smell sewage, keep family members and pets out of the area and avoid touching the water. Sewage cleanup requires protective equipment, safe removal of contaminated materials, and professional disinfection.

2. Stay Safe, Then Stop the Source

Never walk into standing water if outlets, cords or appliances may be submerged. If your electrical panel is in the basement and you can't reach it from a dry spot, wait for help. If a sump pump has failed and power is available, check whether it has tripped or clogged. If a supply line is leaking, close the main water shutoff.

3. Document the Damage for Insurance

Take photos and video of the water, the source, and damaged items before anything is moved. Sewer backups are often covered only when a policy includes a sewer or water backup endorsement, so it's a good idea to call your agent early and ask.

4. Get Water Out and Drying Started Quickly

Mold can begin growing within 24 to 48 hours on wet drywall, carpet and wood. Professional extraction equipment removes water quickly, and industrial air movers and dehumidifiers dry the structure itself. Our IICRC-certified technicians monitor moisture daily until materials are properly dry.

If belongings need to be moved while the basement dries, our contents pack-out service inventories, cleans and stores them safely.

5. Prevent the Next One

After cleanup, consider a battery backup for your sump pump, a backwater valve if recommended by a plumber, and keeping valuables off the basement floor. If the water sat for a while before it was found, mold testing can confirm the area is safe.
