Crawlspace Encapsulation in Idaho Falls, ID

Winter heating bills causing problems in your Idaho Falls home? A vented crawlspace is the #1 cause. Closed-cell spray foam encapsulation solves it permanently.

How Crawlspace Encapsulation Works

Most Idaho Falls homes have a vented crawlspace under the first floor. In our climate, that vented space brings in ground moisture, pests, and winter heating bills that affects the rooms above. Floors feel cold, humidity is higher than it should be, and HVAC has to work harder.

Encapsulation reverses all of this in 2 days:

1. Remove existing fiberglass batts and old vapor barrier
2. Install a thick (12-20 mil) vapor barrier on the dirt floor and up the walls
3. Spray closed-cell foam on the walls (and rim joist) to seal air infiltration
4. Optionally add a small dehumidifier to maintain ~50% humidity

What you'll notice:

• Floors feel warmer immediately
• Humidity in living space drops 10-20% in the first week
• HVAC runs less (typical: 15-25% reduction)
• No more pest entry points
• Permanent fix — not a band-aid

Pricing in Idaho Falls:

A typical 1,200-1,800 sq ft crawlspace encapsulation runs $5,000–$8,000 depending on access, current condition, and whether dehumidifier and sump pump add-ons are needed. We provide a fixed-price written quote at the in-home estimate.
