See the honest number first.
Five questions, no email gate, no “sign tonight” sales hook. Same range we'd write on a quote at the kitchen table.
Most contractors hide the number until they're in your living room.
Pricing transparency is the #1 complaint Twin Cities homeowners have about the waterproofing industry. The national franchises run sales-heavy operations with monthly quotas — they want you in a room with a closer before you see a real number. We don't.
This calculator outputs the same range we'd quote at your kitchen table. The exact number depends on what we find at the inspection (buried mechanicals, soil conditions, existing infrastructure that wasn't visible from outside) — but the ballpark is the ballpark. If you want the line-item breakdown of what drives the number, read the full 2026 cost guide.
Have a quote from another waterproofer that's outside our range? Bring it to the inspection. We'll tell you honestly whether they're selling a different product (often the case) or whether their number is actually fair (sometimes the case). Apples to apples is what matters.
What's a basement like yours actually cost?
A few questions, no email required. Results show immediately. The number you see is the same range we'd quote at the kitchen table.
