Insulation

Crawl space encapsulation is one of those phrases that sounds like a single product.

In real life it’s a stack of mini-projects that can range from:

• “lay a vapor barrier so the ground stops sweating into the house”
• to “turn this crawl space into a sealed, dehumidified, insulated mini-basement”

Both can be described as encapsulation. Both can be quoted in the same email template. And the price can swing from “okay” to “why does this cost more than my car?”

This post is basically my Notes app, cleaned up just enough that it’s readable.

Because the real file looks like:

“attic guy #1: $2,950 (fast)”

“attic guy #2: $6,480 (air seal?? baffles??)”

“attic guy #3: $14,600 (spray foam voice. very confident)”

And then: “why are these numbers not even in the same universe.”

Also, small confession: I didn’t grow up thinking about R-values.

I grew up thinking about “why is the upstairs always 8 degrees hotter” and “why does the hallway smell like attic dust when the furnace turns on.”
