Frequently Asked Questions About Attic Insulation
How do I know if my attic needs more insulation?
If you notice high energy bills, uneven temperatures between rooms, or visible attic joists, it may be time to upgrade your insulation. Most homes in Michigan are under-insulated for our climate.
What type of insulation is best for Michigan attics?
Blown-in cellulose is ideal for most attics in our region. It provides excellent thermal protection and sound dampening. For problem areas or complex rooflines, spray foam may be recommended.
Will I qualify for rebates or tax credits?
Yes! Michigan residents may qualify for up to $1,200 in Consumers Energy rebates, plus federal tax credits. We handle the rebate paperwork for you.
How long does an attic insulation job take?
Most attic insulation installs take just a few hours. We arrive on time, prep the area, and clean up fully before leaving—typically done same-day.
