Disclosures

Where the pictures come from, what the prices mean, and what we don’t claim.

Prices

Every price on this site, the estimator included, is a ballpark worked out from what you enter: about $3.50 a square foot for full encapsulation, about $1,600 for a dehumidifier, and a $2,500 minimum. They are not quotes. We confirm a firm price in writing after a look under the house, before any work starts.

Market figures in the guides come from the published sources linked beside them, as they stood in October 2026.

Photos

The photos on this site are openly licensed images from Wikimedia Commons and Flickr, and public domain survey photographs. They show crawl spaces, building materials and the towns we work in. None of them shows our own jobs, crew or customers. Each is credited here with its creator, its licence and a link to its source.

Some were cropped or darkened to fit the layout. Photos under a CC BY-SA licence stay under that licence in their cropped form. The cross-section drawing of a crawl space on the home page was made for this site.

What we don’t claim

We don’t publish reviews, ratings, awards or certifications we don’t have. Energy and humidity figures come from the studies linked in the guides; your crawl space may do better or worse. Encapsulation is not radon mitigation, and it is not structural engineering.
