From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Mount Prospect before. We show up, we diagnose it straight, and we fix it right.

📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Mount Prospect technicians hear about most often before an inspection.
Odor is often the first sign Mount Prospect customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Mount Prospect-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Mount Prospect call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Mount Prospect property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Storm season in Mount Prospect, IL means our emergency line gets busy fast — we triage calls by severity so active flooding at your Mount Prospect address jumps the queue ahead of routine inspections.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Mount Prospect crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Mount Prospect lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →Some Mount Prospect lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
