A musty smell usually means moisture is already moving through your Port Jefferson basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.

Peeling paint near the floor upstairs is one of the last signs Port Jefferson homeowners connect to a basement problem.
No two Port Jefferson basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
