Welcome to Lewis Insulation

Exterior Wall Home Insulation

Twin Cities Insulation Contractors

Lewis Insulation, Inc. is a full-service insulation company serving the Twin Cities Metro. We have been re-insulating existing homes and insulating new homes, additions and home remodels since 1974. A home that is well insulated is more energy efficient, comfortable, quiet and will save you money on utility bills for years to come. By using less energy to heat and cool your home, you reduce the negative impacts on the environment caused by excessive energy use.

Whether you want to lower your energy bills, remodel your current home or build a new custom home, Lewis Insulation shares your goals of creating a comfortable, healthy and energy efficient indoor environment.

The purpose of insulation is to keep your home warm in the winter and cool in the summer. We offer several common types of insulation; fiberglass (blown-in & batt form), blown-in cellulose, and closed cell spray foam. When correctly installed with air sealing, each type of insulation can deliver comfort and lower energy bills during the hottest and coldest times of the year.
Thank you for visiting our website. We are confident in the insulation services we can provide for you. We lead the industry in high quality, dependable & complete insulation solutions.

Customer Testimonials What Do Our Customers Have To Say?

“ I would recommend Lewis for insulation work. We will most likely have them come out again for a quote on blowing insulation into our walls later this year. I was very impressed with them, and their price is very reasonable for the quality of work you get, as well as the peace of mind knowing that you have a crew who actually cares doing the work.”
