About Custom Superior Insulation - Insulation Contractor in Superior, WI

Custom Superior Insulation was founded in 2018 by people who know this part of Wisconsin well. Superior sits at the western tip of Lake Superior, where winters are long, temperatures drop well below zero, and the moisture coming off the lake finds its way into homes that were not built to handle it. Most of the housing stock here was built before modern insulation standards existed, and homeowners have been dealing with the consequences ever since - high heating bills, cold rooms, and damp crawl spaces that never quite dry out.

We started this business because we saw how many homes in Superior and across the surrounding area were losing heat through attics, rim joists, and crawl spaces that had never been properly insulated. Some of those homes had been in families for generations. Others were being rented out by landlords trying to keep aging properties livable. In nearly every case, the fix was straightforward - but it needed someone who understood what Wisconsin winters actually do to a house.

Today we serve homeowners and property owners across 12 communities in Wisconsin and Minnesota. Whether your home is near Barker's Island, out in Billings Park, or across the bridge in Duluth, we have worked on homes like yours. We are a small company by design - we do not sub out the work and we do not rush jobs. When we finish, you know exactly what was done and why.
