Frozen pipes, heating bills that keep climbing, and floors too cold to walk on barefoot all point to the same problem: the space under your home is working against you. At Peak Spray Foam Insulation, we install the crawl space insulation Annandale, MN homeowners count on to hold off brutal Minnesota temperature swings, stop energy waste, and build a healthier living space that pays off for decades.
Not every insulation material can survive the damp, harsh conditions found under a Minnesota home. Fiberglass batts, long the go-to pick for builders, soak up moisture, pull away from joists, and quit working within just a few years in crawl space settings. Spray foam has taken over as the favorite for Minnesota homeowners because it expands into every crack, pushes back moisture, and keeps its insulating power for decades without breaking down.
Our team points every customer toward closed-cell spray foam as the best insulation for crawl space applications in Annandale and the surrounding area. It delivers an R-value of R-6.5 to R-7 per inch, nearly double what fiberglass manages, while acting as a thermal barrier and a moisture seal in a single application. ENERGY STAR treats air sealing and insulating enclosed crawlspaces as a core home project, and the Building America research behind its guidance matches what our crew sees on job sites every week.

Crawl space insulation cost shifts with a handful of details: the size of the space, the shape it is in, and whether you pick basic floor insulation or full encapsulation. Basic floor insulation generally lands between $1,000 and $4,000, while full encapsulation with spray foam runs $4,000 to $13,500. That upfront money comes back over the years through cheaper utility bills, fewer repairs, and a structure that holds up longer.

Spray foam grips directly to the surfaces it touches, swelling to fill gaps and cracks that old-school materials never reach. The result is an airtight barrier that blocks moisture, discourages pests, and stops conditioned air from leaking through the floor above. Unlike fiberglass, crawlspace spray foam insulation will not sag, settle, or lose R-value as the years pass, which makes it a smart long-term buy for any home.

Every crawlspace insulation installation begins with a close look at the space under your home. Our technicians hunt for standing water, inspect the condition of any existing insulation, review ventilation, and flag air sealing opportunities. Getting this evaluation done first means we fix the true causes of your comfort and efficiency problems rather than just the symptoms.
The work itself usually wraps up in one to two days, depending on the size and complexity of your crawl space. We close off vents, lay a reinforced vapor barrier across the ground, and spray foam the areas your plan calls for. Every stage gets our full attention, and we walk you through the finished space before we leave your Annandale property.
