Comprehensive Insulation Services in Madison, WI



Attic Insulation & Air Sealing

The attic is one of the biggest sources of energy loss in a home. Without proper insulation and air sealing, warm air escapes in the winter and hot air seeps in during the summer. Duerst installs blown-in cellulose, fiberglass, and closed-cell spray foam insulation designed specifically for Wisconsin homes. Every attic project includes professional air sealing, which blocks drafts, prevents ice dams, and keeps conditioned air inside where it belongs.

Wall Insulation for Existing Homes

Older homes in Madison often have little or no wall insulation, which leads to high energy bills and uneven room temperatures. We specialize in dense-pack cellulose and spray foam wall insulation. These materials are installed with minimal disruption, improving comfort, reducing noise between rooms, and increasing energy efficiency without costly remodeling.

Basement and Crawl Space Insulation

A poorly insulated basement or crawl space allows cold air and moisture to infiltrate the rest of the home. Our technicians install durable insulation systems for foundation walls, rim joists, and crawl spaces to eliminate drafts, reduce humidity, and prevent mold growth. This service not only makes your home more comfortable but also protects the structure for years to come.

Spray Foam Insulation in Madison

Older homes in Madison often have little or no wall insulation, which leads to high energy bills and uneven room temperatures. We specialize in dense-pack cellulose and spray foam wall insulation. These materials are installed with minimal disruption, improving comfort, reducing noise between rooms, and increasing energy efficiency without costly remodeling.

Insulation Removal & Replacement

Old insulation can become damaged by pests, water leaks, or mold. Inefficient or contaminated insulation not only reduces energy savings but can also harm indoor air quality. We provide safe and thorough insulation removal, followed by replacement with modern, high-performance materials that restore comfort and safety to your home.

Soundproofing Services

Noise control is another benefit of proper insulation. Duerst offers soundproofing solutions for interior and exterior walls, ceilings, and floors. Whether you want a quieter home office, media room, or just a more peaceful living environment, our insulation systems help block unwanted noise.

Concrete Lifting & Leveling

In addition to insulation, we provide professional concrete lifting and leveling services throughout Madison. Uneven or sunken concrete slabs are not only unsightly but also hazardous. Using modern methods, we lift and stabilize driveways, sidewalks, patios, and garage floors, restoring both safety and curb appeal.

Energy Audits and Rebates in Madison

Every home is different, which is why Duerst begins with a professional energy audit. This comprehensive assessment identifies problem areas such as air leaks, poor insulation, or moisture issues. Once complete, we provide clear recommendations and help you qualify for energy efficiency rebates.

Through Wisconsin’s Focus on Energy program and the federal IRA-HOMES program, homeowners can save thousands of dollars on upgrades. Unlike many contractors, we apply rebates up front—meaning you don’t have to wait for reimbursement. This makes upgrading your home’s insulation easier and more affordable.
