How the calculation works
The calculator totals area-based liner and labor costs, adds drainage, dehumidification, treatment and permit costs, then applies contingency.
Important limitations
Access, crawl height, water intrusion, structural repairs, mold, insulation removal, local labor, drainage and code requirements can change actual bids.
