Common Questions

About this service

Do you install the encapsulation?

No. We assess the crawlspace, develop the scope of work, and hand it to you — so you can shop the install to qualified contractors with a vetted spec in hand. Independence from the install is the whole point.

What about basement waterproofing?

Same model. We scope what needs to happen (interior drain-tile, sump, exterior membrane, vapor management) and you bid the install to a qualified contractor. See our waterproofing service for details.
