Cost questions we get every week
Is the estimate really free?
Yes. Coming out to look at a leak or a crack and giving you a written price costs nothing, with no obligation.
Why is the range so wide for waterproofing?
It’s priced by the foot of wall. One leaking corner might need 20 feet of drain tile; a whole basement can need 150 feet or more. Exterior work also depends on depth, decks, driveways and how close the house next door is.
Interior or exterior waterproofing: which is cheaper?
Interior is usually less per foot because we work from inside the basement. Exterior costs more because we excavate down to the footing, but it stops water before it reaches the wall. Here’s how to choose.
Do you charge by the hour?
No. We price by the job, so the number we give you is the number you pay unless you add work.
Can I make monthly payments?
Yes, financing is available through our lending partner. Use the payment calculator to see examples.
