π +1-866-476-1348Most Centereach customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Even small cracks are worth a second look β they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence β mineral deposits left behind as water evaporates through concrete.

A bowing basement wall is a structural concern in addition to a water one β this is the kind of Centereach call we prioritize fast.
These signs upstairs are often the last clue Centereach homeowners notice, even though the moisture issue started in the basement months earlier.
