What We Do

Comprehensive Foam & Coating Solutions

From attic insulation to commercial roof coatings, we deliver results that stand the test of time and weather.

Spray Foam Insulation

High-performance closed-cell and open-cell foam that seals gaps, boosts R-value, and dramatically reduces heating and cooling costs in any Wisconsin home.

Roof Coatings

Protective elastomeric and reflective roof coatings that extend roof lifespan, prevent leaks, and reduce heat absorption — especially valuable on flat and low-slope commercial roofs.

Concrete Sealing

Professional concrete sealing and coating for garages, basements, warehouses, and parking structures — resisting moisture, chemicals, and heavy wear.

Fireproofing

Intumescent and passive fireproofing coatings that protect structural steel and building components, meeting code requirements while maintaining clean aesthetics.

Air Sealing

Targeted foam application that eliminates drafts, blocks moisture intrusion, and stops pests — creating a tighter building envelope that works harder so your systems work less.

Moisture & Mold Control

Closed-cell foam acts as a Class II vapor barrier, preventing condensation, mold growth, and structural rot — critical protection for Wisconsin's seasonal humidity swings.

About Us

Built on Craft, Driven by Results

Extreme Foam and Coatings was founded on a simple belief: every building deserves protection that actually lasts. Based in Princeton, Wisconsin, we specialize in spray foam insulation and protective coatings for homeowners, property managers, and commercial operators throughout the region.

Wisconsin weather is unforgiving — freezing winters, humid summers, and everything in between. That's exactly why standard insulation and coatings often fall short. Our materials and application methods are chosen specifically for this climate, delivering an airtight seal and a barrier that won't degrade, settle, or fail when you need it most.
