Elmhurst’s own stormwater plan names five different ways a home here floods, and the city and county have built a levee and a flood-control quarry to fight just one of them.

Why Elmhurst homes leak
Salt Creek overbank flooding is the kind Elmhurst has largely tamed: a levee over a mile long protects more than 1,400 homes, and DuPage County’s Elmhurst Quarry Flood Control Facility, built inside a former stone quarry starting in 1993, holds 8,300 acre-feet of floodwater. The other four flooding types in the city’s plan – street flooding, overland flow, sanitary sewer backup and seepage – still reach basements. Sanitary backups come from clean water infiltrating aging pipes, and the city spends nearly $1 million a year lining sewers to fight it. Elmhurst is blunt that a home connected to the sanitary system without backflow protection “will always be at risk,” which is why it offers a cost share of up to 50% (capped at $5,000) toward an overhead sewer. Around all of this sits DuPage County’s dense clay soil, which holds stormwater against foundation walls instead of letting it drain, and much of the housing stock predates modern drainage codes. Every Safe Seal job starts with a free inspection and a written plan, because a sewer backup problem and a groundwater seepage problem need different fixes.

Frequently asked questions
How much does basement waterproofing cost in Elmhurst?
It depends on where the water is coming in. A simple crack repair costs far less than a full interior drain tile system. After a free inspection we give you a written, fixed quote so you know the full cost before any work starts.
How long does a typical job take?
Most crack repairs and sump pump installations finish in a day. Full interior or exterior waterproofing systems usually take two to five days depending on the size of the home.
Do you warranty your work?
Yes. Our waterproofing work carries a lifetime warranty.
Should I waterproof from the inside or the outside?
Interior systems manage water that is already reaching the foundation and are less disruptive. Exterior systems stop water before it reaches the wall but require excavation. We recommend whichever actually solves your problem after inspecting the home, and we explain the trade-offs in plain terms.
Do you also handle crawl spaces?
Yes. We encapsulate crawl spaces with vapor barriers, drainage and sealing to stop moisture, mold and musty smells at the source.
