Know the Signs

Why Is Your Basement Flooding?

Not every flooded basement has the same cause. What you're seeing, or smelling, is the first clue to what's actually happening.

Floor Drain Backs Up After Heavy Rain

Water coming up through the floor drain points to the sewer side: a blocked private line or a connection that can't keep up.

Water Seeping Through the Walls

Water along the base of foundation walls is groundwater, not sewage. That's a sump and waterproofing problem.

Sump Pit Filling Faster Than Normal

A pit that fills even between storms means a high water table, and a pump working harder than it should.

A Sewage Smell From the Drains

Visible sewage or a sewer smell coming up through the drains is a backup. Stop using water and call.

Local Knowledge

Basement Flooding in Highland Park Homes

Heavy rain and spring snowmelt push water toward Highland Park basements every year. How it gets in depends on your home.

Separate Storm and Sanitary Sewers

Highland Park runs separate sanitary and storm sewers, about 120 miles and 163 miles of each. So a wet basement here isn't always a sewer backup. It could be groundwater, a blocked private sewer line or a failed sump pump, and each needs a different fix.

What the City Recommends

The city's flood tips recommend checking backflow preventers, sump pumps and battery backups, and having your sewer line checked for roots and debris. An overhead sewer system is the permanent fix when the connection itself can't keep up.

Older Homes, Finished Basements

Nearly half of Highland Park homes were built before 1960, often before modern flood protection was standard. A finished basement in an older home has the most to lose, so it's worth knowing which protection you have.

Basement Waterproofing

Basement Waterproofing

Waterproofing is the right fix when water is forcing its way through the foundation, not backing up through a drain. Signs include damp walls, water along the joint where the wall meets the floor, efflorescence (white, chalky deposits) and puddles that show up after rain without any drain backing up.

Waterproofing works together with a sump pump: the system directs groundwater to the pit, and the pump moves it out and away from the house. Before recommending anything, we confirm the water is coming through the foundation and not from a plumbing leak or a sewer backup, so you don't pay to fix the wrong problem.

"John was very professional and knowledgeable, he quickly helped us drain our flooded basement and left us feeling confident in the work he had done. Confidence is priceless when it comes to plumbing."

"We initially called and Edgar came when we had flooding in our basement, and throughout multiple days of different issues being found, he talked us through each piece, explaining our options, and kept in close communication about the progress and everything that had come up. He helped clear our drain, then fixed some piping in the basement, put a liner in our pipes, and installed a sump pump, staying late to ensure we had working plumbing."

Jake Sherin

"We are SO impressed with our service from J Blanton. Jacob C. was incredibly professional and quickly diagnosed our sump pump issue. Being newer to the area we did not have a plumbing company- and we found our forever company for any future issues!"

Basement Flooding Questions From Highland Park Homeowners

A licensed plumber first, to stop the source. Cleanup and restoration come after.

Call a licensed plumber first. A water damage company handles cleanup and restoration, but if water is still entering your basement, the source needs to be stopped before any cleanup is effective. We identify what's causing it and make the fix. Once the water is stopped, restoration can begin.

It depends on the cause. A sump pump handles groundwater, not sewer backups.

It depends on what's causing the flooding. A sump pump handles groundwater. It won't stop water backing up through a floor drain from the sewer side, and it won't stop water forcing through foundation walls. Because Highland Park runs separate storm and sanitary sewers, pinning down which water you have is the first step.

A sump pump removes groundwater. An ejector pump moves wastewater from basement fixtures up to the sewer.

A sump pump removes groundwater. It sits in a pit at the lowest point of the basement and pumps water out of the house. An ejector pump moves wastewater from fixtures below the main sewer line, like a basement bathroom or laundry room, up to the main sewer level.

Often not for groundwater or sewer backup. Check your policy. We document the cause for your claim.

Standard homeowners insurance typically does not cover flooding caused by groundwater, sewer backup or heavy rain. Those events usually require separate flood insurance or a sewer backup rider. If the flooding is caused by a sudden plumbing failure, like a burst pipe, your standard policy may cover it. Check your policy or contact your insurer to confirm. Our technician will document the cause, which may support your claim.

It depends on the cause and the fix. You get a flat-rate price before any work starts.

The cost depends on what's causing the flooding and what fix is required. A sump pump replacement is a different scope than an overhead sewer installation or waterproofing. We provide a flat-rate price before any work starts. Give us a call.
