Our Services in Cross Plains, WI

Attic Insulation & Air Sealing

Attics are one of the biggest sources of energy loss in Wisconsin homes. We install blown-in cellulose or fiberglass alongside detailed air sealing to block heat loss, prevent ice dams, and improve overall home comfort. A properly insulated attic reduces strain on your HVAC system and stabilizes indoor temperatures throughout the year.

Wall Insulation for Existing Homes

Many Cross Plains homes—especially mid-century and older builds—lack adequate wall cavity insulation. Our dense-pack insulation process fills these cavities behind existing drywall or siding with minimal disruption. This increases comfort, reduces sound transfer, and significantly lowers heating and cooling bills.

Basement and Crawl Space Insulation

Cold floors, musty odors, and winter drafts often originate from poorly insulated basements or crawl spaces. We insulate foundation walls, rim joists, and sill plates to block moisture, reduce air leakage, and improve the overall comfort and health of your home.

Spray Foam Insulation in Madison

Spray foam insulation is one of the most effective ways to boost energy efficiency in Wisconsin’s demanding climate. We install open-cell and closed-cell spray foam based on your home’s structure and needs. Spray foam expands to seal air leaks, delivers high R-value performance, limits moisture intrusion, and is ideal for attics, basements, rim joists, crawl spaces, garages, and irregular framing. Its powerful insulating and air-sealing properties help maintain consistent indoor temperatures and reduce year-round energy usage.

Insulation Removal & Replacement

Old or damaged insulation—especially material affected by moisture, pests, or age—leads to poor performance and can compromise indoor air quality. We safely remove deteriorated insulation and replace it with modern, high-efficiency materials designed for Wisconsin’s climate.

Soundproofing Services

Whether outfitting a home office, media room, workshop, or multi-family property, our sound-dampening insulation systems help reduce noise transfer between rooms and floors. We tailor solutions to your home’s design and noise-control goals.

Concrete Lifting & Leveling

Cross Plains’ varied terrain and freeze–thaw cycles can cause concrete slabs to sink or become uneven. We lift and level sidewalks, driveways, patios, garage floors, and other concrete surfaces to eliminate trip hazards, restore proper drainage, and prevent further settling—without the expense of full replacement.

Energy Audits and Rebates in Madison

We begin each project with a detailed evaluation of your home’s insulation, thermal efficiency, and air leakage points. Through Wisconsin’s Focus on Energy program and federal efficiency incentives, we apply qualifying rebates directly to your project cost—no waiting, no paperwork delays.



This makes insulating your Cross Plains home more affordable and more impactful.
