Common questions before you call anyone

Why do Metro East basements leak after the storm, not during it?

Short answerMetro East sits on shrink-swell clay. Clay sheds water slowly, so rain collects in the backfill trench beside your foundation and drains toward the wall for hours after the sky clears. That lag is the signature of a hydrostatic problem, not a roof or gutter problem.

Is interior drain tile or exterior excavation the right fix here?

Short answerIn Metro East clay, interior drain tile is the usual answer because exterior excavation has to move the same heavy clay twice and costs roughly three times as much for the same dry floor. Exterior work wins when the wall itself is failing or the seepage is above grade.

What does a full basement waterproofing job cost in the Metro East?

Short answerMost Metro East homeowners see interior drain tile bids between $6,000 and $12,000 for a typical 1,200 to 1,800 square foot footprint, with sump and backup work quoted separately. Partial-wall systems land lower; full perimeter with a new pit lands higher.
