📞 +1-866-476-1348Most Prospect Heights customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Prospect Heights customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Prospect Heights-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Prospect Heights storm.
