Our Services in Verona, WI

Attic Insulation & Air Sealing

A poorly insulated attic is one of the largest sources of energy loss. We install blown-in fiberglass, cellulose, or spray foam systems to enhance R-values and eliminate heat escape. Every attic project includes thorough air sealing to reduce drafts, prevent ice dams, and increase year-round comfort.

Wall Insulation for Existing Homes

Many Verona homes—especially older builds—lack proper wall cavity insulation. Our dense-pack and spray foam methods allow us to insulate behind existing drywall with minimal disruption. This dramatically improves interior comfort, reduces noise transfer, and lowers utility costs.

Basement and Crawl Space Insulation

Cold floors, moisture problems, and drafts often originate in the basement or crawl space. We insulate foundation walls, rim joists, and sill plates to stop cold infiltration and humidity. This not only improves comfort but helps protect your home from mold growth and structural deterioration.

Spray Foam Insulation in Madison

Spray foam insulation provides exceptional air sealing, high R-values, and moisture resistance in one application, making it one of the most effective solutions for Wisconsin homes. We install both open-cell and closed-cell spray foam depending on the project’s needs—open-cell for sound control and flexible coverage, and closed-cell for maximum insulation, strength, and moisture protection. Spray foam is ideal for attics, rim joists, crawl spaces, basements, garages, and irregular areas where traditional insulation falls short. Its ability to expand and seal even the smallest gaps helps eliminate drafts, stabilize indoor temperatures, and deliver long-term energy savings.

Insulation Removal & Replacement

Old, damaged, or contaminated insulation cannot perform effectively. Whether the issue is moisture, pests, or age-related deterioration, our team safely removes compromised material and installs modern insulation that restores efficiency and indoor air quality.

Soundproofing Services

For home offices, entertainment rooms, multi-family buildings, or simply creating quieter living spaces, our sound-dampening insulation solutions greatly reduce noise transfer. We apply specialized insulation strategies in walls, ceilings, and mechanical areas to enhance privacy and comfort.

Concrete Lifting & Leveling

Sunken or uneven concrete slabs can create trip hazards, drainage issues, and curb appeal problems. Our concrete lifting service restores sidewalks, driveways, patios, garage floors, and other slabs to a safe and even position. This process extends the life of your concrete without the cost of full replacement.

Energy Audits & Rebates for Verona Homeowners

Every project begins with a detailed energy assessment. We evaluate insulation levels, air leakage, moisture concerns, and overall thermal performance. Verona homeowners benefit from our expertise with:

• Focus on Energy rebates
• IRA HOMES program savings
• Upfront rebate application—you pay less on day one

This makes improving your home’s efficiency more affordable than ever.
