  • Exterior walls with ice formation
  • Icicles on the edge of your roof

Do I Have To Get All New Insulation If I Have Ice Dams?

 Some ice dams lead to wet insulation and attic mold growth.  In this case, new house insulation is necessary.  In other cases, tweaks to ventilation and attic air sealing can occur. It’s important to know that something as simple as a bath fan venting into the attic can cause ice dam formation.

Can I Have Ice Formation On My House Even If My Insulation And Ventilation Are Adequate?

Roof icicles can happen as part of Wisconsin and Minnesota’s freeze/thaw cycle.  It’s important to know that not every ice dam has icicles.  In the same way, roof icicles, do not always signal an ice dam.

Reviews Of Our Insulation Contractor Services:

"Randall Bowman and an attic insulation crew attended to my Somerset, WI condo in Oct. 2023.  They were ahead of schedule, very conscientious about not causing any damage or mess in the house. Very conscientious about not blocking traffic for my condo development neighbors. And, they were very efficient-- finishing earlier than they estimated. I would highly recommend Lindus Construction and the two insulation company they contract with."

"Jake was very helpful and responsive in getting through this catastrophic event when a huge chunk of ice crashed through our family room ceiling. He was helpful in discussions with insurance company, especially as when they sent out an evaluator he spent less then 20 minutes on the job, then disappeared."
