Boise's Specialist for Stabilization
Up to 50% of the air you breathe upstairs originates in your crawl space. If it's damp, moldy, or infested, that air is being pulled into your living space every day. Encapsulation fixes the problem permanently.
Understanding the "Stack Effect"
Your home acts like a giant chimney. Warm air rises and escapes through the attic, creating negative pressure that sucks replacement air up from the lowest point—your crawl space.
This means:
- Mold spores from a damp crawl space end up in your living room.
- Humidity makes your HVAC work harder, raising utility bills.
- Odors (especially musty or "wet dog" smells) filter into bedrooms.
- Allergens and dust mites thrive in moist environments and get distributed throughout the home.
Why Treasure Valley Crawl Spaces Are Especially Vulnerable
Traditional "vented" crawl space design was meant to let moisture escape. It doesn't work in Idaho's climate:
- Summer: Hot, humid air enters the cold crawl space and condenses on cool surfaces (pipes, ducts, floor joists)—creating the perfect environment for mold.
- Winter: Freezing air enters the vents, chilling your floors and pipes (burst pipe risk).
- Flood Irrigation: In many Meridian and Nampa subdivisions, canal water raises the local water table, pushing moisture up through the soil.
Our Encapsulation Process
We don't just lay plastic on the floor. We build a complete sealed system:
1. Debris Removal & Prep
We remove old insulation, debris, and any standing water. If water intrusion is active, we install a sump pump or French drain first.
2. Heavy-Duty Vapor Barrier
We install a 20-mil reinforced polyethylene liner across the entire floor and up the walls—secured with specialized tape and fasteners. This completely blocks ground moisture.
3. Vent Sealing
All foundation vents are closed and sealed. We're converting your crawl space from "outside" to "inside" your home's thermal envelope.
4. Wall Insulation
We apply closed-cell spray foam or rigid foam board to the foundation walls. This insulates the space and acts as an additional moisture barrier.
5. Dehumidification
A commercial-grade dehumidifier is installed with a drain line to automatically maintain relative humidity below 50%—the threshold where mold cannot grow.
Benefits You'll Notice Immediately
- Warmer Floors in Winter: No more cold feet—insulated crawl space means insulated floors.
- Lower Energy Bills: Your HVAC ducts now run through conditioned space, not a freezer/sauna.
- No More Musty Smell: The source is eliminated, not masked.
- Pest Protection: Sealed vents and a clean floor make your crawl space less attractive to rodents and insects.
- Structural Protection: Floor joists and subfloor are protected from rot and moisture damage.

Sinking Garage Stabilization
A homeowner in the area noticed a 1-inch separation between their garage floor and the foundation wall. Our diagnostic confirmed the home was built on uncompacted fill soil near an old irrigation lateral.
