Water and crawl spaces

Exterior excavation and membrane waterproofing

Tier C · 17 towns covered

Excavating to the footing and sealing the outside face of the wall. The most involved fix, and sometimes the only one that works.

This comes up often enough around here that most local contractors have a settled way of handling it.

The things people ring up about

Interior fixes that have already been tried and have not held
Water entering along a specific stretch of wall rather than everywhere
Visible damage to the outside face of the foundation
A finished space you would rather not tear out from the inside

What the work involves

This means excavating down to the footing and sealing the outside of the wall, usually with drainage board and a new drain line. It is the most disruptive option and sometimes the only one that works.

$12,000 – $20,000 — typical range, not a quote. What your home needs can only be settled by a registered contractor who comes out and looks at it.

Coverage

Where this work gets done

Grouped the way the ground actually varies across the county.

Inland mainland

Inland streets where the ground drains fast but the water table still comes up to meet the floor.

Bayfront and lagoon

Filled lots cut back from the bay, where a crawl space can be damp on a dry day because the tide is up.
