FAQs About Window Installation in the Twin Cities

Close

How much does window installation cost?

It depends on the number of windows, frame type, and materials. Most Twin Cities homeowners can expect to pay $500–$1,200 per window installed. We offer free quotes so you know your exact cost upfront.

Will new windows really save on energy bills?

Absolutely. Replacing old, drafty windows can reduce heating and cooling costs by 10–25%, especially in extreme Minnesota winters.

How long does window installation take?

Most installations are completed in one day. We coordinate everything for minimal disruption to your schedule.

Do I need to be home during the installation?

It’s helpful but not always necessary. We’re flexible and can accommodate your needs.

What’s the difference between window repair and installation?

Repair is a good option if the damage is minor (like replacing hardware or glass). For major issues or old, inefficient units, full replacement is often the smarter long-term choice.
