How much does basement waterproofing cost?

$3,000 to $12,000 on average. Interior drainage is $3,000 to $10,000; exterior excavation is $8,000 to $25,000.

Interior or exterior waterproofing?

Interior drain tile manages water that gets in and costs far less. Exterior membrane keeps water out entirely and is the permanent fix, at two to three times the price.

How much is a sump pump?

$1,000 to $3,000 installed, plus $500 to $1,500 for a battery backup that keeps working during a storm outage.

Is waterproofing covered by insurance?

Groundwater seepage is excluded from standard homeowners policies. Separate flood insurance or a water backup endorsement is required.

Will waterproofing fix mold?

It stops the moisture source, but existing mold needs separate remediation, typically $1,500 to $6,000.

Does a dry basement add value?

Yes — a documented, warrantied waterproofing system removes a major buyer objection and enables finishing the space.

Ways to save in Yonkers

Do the cheap exterior fixes first — gutters, downspout extensions and grading solve many wet basements for under $1,000.
Choose interior drain tile over exterior excavation unless the wall itself is failing.
Get bids from waterproofing specialists and a general contractor; approaches and prices differ enormously.
Ask about a transferable lifetime warranty — it holds value at resale.
Install the sump and drainage before finishing the basement, never after.
