COST OVERVIEW

WHAT DOES WATERPROOFING COST?

Basement waterproofing in the Finger Lakes typically costs between $2,000 and $15,000 for most homes. Simple fixes like crack injection start around $300, while complete exterior waterproofing can exceed $20,000.

The right solution depends on your water source, foundation type, and budget. Most Finger Lakes homes benefit from interior drain tile systems — effective, affordable, and minimally disruptive.

Finger Lakes Factor

High water tables near the Finger Lakes and clay-heavy soils mean many homes need more robust solutions than homes in drier regions. We design systems specifically for our local conditions.

Waterproofing Cost FAQs

It depends on your situation. Interior systems are more affordable and effective for most homes — they manage water that enters and direct it to a sump pump. Exterior waterproofing stops water from ever entering but costs 2-3x more and requires excavation. For most Finger Lakes homes, interior drainage is the best value.
