Frequently asked questions
Is a permit needed to waterproof a basement?
Interior drainage is often treated as maintenance, but adding a sump discharge, altering plumbing or excavating against the foundation usually triggers a permit. Ask the local building department before work starts.
Does interior drainage fix the cause?
It manages water that has already reached the wall. When the cause is grading, gutters or a downspout discharging beside the foundation, correcting that outside is cheaper and should come first.
How long does basement waterproofing take?
2-5 days of work. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are interior drain tile versus exterior excavation and membrane; linear feet of wall treated and the number of sump pits; concrete breakout and replacement inside the slab.
