Matt Mader in Kilkenny is a true professional in spray foam insulation. He is a master at figuring out whatever you need help with. Hardworking, honest and fair. If you need any insulation in southern Minnesota call Mader insulation.

Hello Matt! I want to thank you on the great job you did in my attic on foaming it, it has saved me, between 36 to 45% over last years energy usage, but to bad they raised the prices up, but paying the same, as two years ago. Thank You…

About insulation contractors in Kilkenny
Insulation contractors add attic, wall and crawlspace insulation and air sealing. Insulation contractors perform air sealing, blow cellulose or fiberglass into attics and walls, install spray foam and rigid foam in basements and rim joists, and help homeowners qualify for energy rebates.
Typical cost: $1,800–$6,000 for attic insulation and air sealing. See the full cost guide
Typical U.S. ranges from industry sources (2024–25); not EdgeLocal data. Your quote will vary with scope, materials and location.
Questions to ask this contractor
- Ask for an energy audit: Blower door tests identify air leaks.
- Confirm target R-value: Northern climates typically aim for R-49 to R-60 in attics.
- Ask about air sealing: Insulation works best after air sealing.
