Our Comprehensive Services in Middleton, WI

Attic Insulation & Air Sealing

The attic is one of the largest sources of energy loss. Warm air escaping in winter and hot air infiltrating in summer both waste energy. We install blown-in cellulose, fiberglass, and spray-foam insulation tailored for Wisconsin homes—every attic project includes professional air sealing to block drafts and prevent ice dams.

Wall Insulation for Existing Homes

Many older homes in Middleton were built with minimal or no cavity insulation. We specialize in dense-pack cellulose and spray-foam wall insulation that significantly improves comfort, lowers utility bills, and reduces sound transfer—all with minimal disruption.

Basement and Crawl Space Insulation

A poorly insulated basement or crawl space becomes a pathway for cold air and moisture. We install insulation systems on foundation walls, rim joists, and crawl spaces that stop drafts, reduce humidity, and help prevent mold growth while protecting your home’s structure.

Spray Foam Insulation in Madison

Spray foam insulation is one of the most effective solutions for maximizing energy efficiency and sealing air leaks in a single application. For Middleton and the surrounding Wisconsin region, spray foam provides unmatched performance during both the coldest winters and hottest summers. Duerst Insulation Technicians delivers expert installation of open-cell and closed-cell spray foam tailored to the unique needs of your home or building.

Insulation Removal & Replacement

Old, damaged, or contaminated insulation (from water leaks, pests, or age) reduces performance and can threaten air quality. Our team safely removes and replaces compromised insulation, restoring your home’s safety and efficiency.

Soundproofing Services

Whether you’re building a media room, home office, or just want more peace and quiet, our sound-dampening insulation services help reduce noise transmission through walls, ceilings, and floors.

Concrete Lifting & Leveling

Uneven, sunken concrete slabs outside your home—such as driveways, walkways, patios, or garage floors—are not only unsightly but can present trip hazards and water-infiltration risks. We apply modern concrete-lifting techniques to stabilize and level these surfaces, improving both safety and curb appeal.

Energy Audits and Rebates in Middleton

Every home is unique, which is why we start with a professional energy audit: a comprehensive evaluation of insulation levels, air leakage, moisture issues, and thermal performance. From there, we deliver clear, actionable recommendations and help you access energy-efficiency rebates.

Through Wisconsin’s Focus on Energy program and applicable federal incentives, homeowners can save significantly on upgrades. Unlike many contractors, we apply rebates toward your project cost upfront—meaning you don’t wait for reimbursement, you start saving immediately.
