In Minnesota, your home’s insulation is just as important as your furnace or air conditioner. Without a proper thermal barrier, the expensive air you pay to heat or cool escapes right through your attic and walls. At Professional Mechanical Services, we provide expert insulation and air sealing for St. Michael homeowners, helping you keep the heat in during the winter and the humidity out during the summer.


With nearly two decades of local experience, we understand the specific building requirements for Wright County. We specialize in high-performance insulation solutions that increase your home's R-value and protect your investment for decades.

Our Insulation & Air Sealing Solutions

We don't just "add more fluff." We provide a comprehensive approach to your home’s thermal envelope:


  • Attic Insulation (Blown-In): We use high-quality blown-in fiberglass or cellulose to reach the recommended R-value for Minnesota homes, filling every nook and cranny that traditional batts might miss.
  • Professional Air Sealing: Insulation works best when air isn't moving through it. We seal common "bypasses" like light fixtures, plumbing stacks, and chimney chases to stop air leaks at the source.
  • Rim Joist Insulation: Often overlooked, the rim joist is a major source of basement drafts. We insulate this area to keep your floors warmer and your basement dryer.
  • Wall Insulation: For older St. Michael homes with empty wall cavities, we can add insulation to significantly improve soundproofing and thermal retention.

FREQUENTLY ASKED QUESTIONS

  • What is the recommended R-value for attics in St. Michael?

    For Minnesota’s climate zone, the Department of Energy and local building codes generally recommend an attic R-value of R-49 to R-60. Most older homes in our area only have R-19 or R-30, meaning they are significantly under-insulated by modern standards.

  • Can I just put new insulation over my old insulation?

    In many cases, yes! As long as the existing insulation is dry and free of mold or pests, we can blow new high-efficiency insulation directly over the top to bring your home up to modern standards.

  • Will new insulation stop ice dams?

    Yes, when combined with professional air sealing. Ice dams are caused by heat escaping from your living space into the attic. By sealing air leaks and adding insulation, we keep the roof deck cool, which prevents the uneven melting and freezing that causes dams.

  • How long does the installation process take?

    Most attic insulation and air sealing projects for a standard St. Michael home can be completed in one day. We work efficiently to minimize any disruption to your schedule.

  • Are there rebates available for insulation?

    Many local utility companies, such as CenterPoint Energy or Xcel Energy, offer rebates for homeowners who perform qualifying air sealing and insulation upgrades. We can help you identify which programs may apply to your project.
