Crawl Space Insulation & Encapsulation

Crawl space insulation in Michigan is the single most overlooked energy upgrade in luxury homes. The crawl space is the foundation that controls how the entire structure breathes — and a damp, vented crawl is a constant drag on indoor air quality, hardwood floors, electronics, and HVAC efficiency. Even the finest custom-built homes can suffer from cold floors, musty smells, and frozen pipes when the crawl is left unsealed.

Our encapsulation system addresses every pathway moisture and cold air use to enter your home. We start with a moisture reading and visual inspection to document existing conditions. If we find mold, we treat it before installing the new system. We then lay down a 20-mil reinforced poly vapor barrier across the floor and walls — far thicker than the standard 6-mil sheeting most contractors use — and tape every seam.

Next, we apply closed-cell spray foam to the rim joist (where the foundation meets the framing) and the foundation walls. Closed cell at R6.5–7.0 per inch is essential here because it acts as both insulation and a vapor barrier in a single application. We seal the crawl space vents permanently and install a commercial-grade dehumidifier sized to the cubic footage to maintain a stable 45–55% humidity year-round.

The result is a clean, dry, conditioned crawl space that protects your hardwood floors, eliminates the musty smell from upstairs, frost-proofs your plumbing, and cuts your DTE heating bills 15–25%. Combined with DTE rebates and the federal 25C tax credit, most Metro Detroit luxury homeowners see meaningful payback within 5–8 years on a system that lasts the life of the home.
