    Signs You Need New Windows

    Wondering if it’s time to replace your windows? Look for these red flags:

    • Drafts or air leaks, especially in winter
    • Fogging between double panes
    • Windows that stick or won’t close properly
    • Peeling or cracked window frames
    • Rising energy bills despite insulation

    If you’re experiencing any of the above, schedule a free inspection with Ascension. In some cases, a professional window repair may be the better option; either way, we’ll help you decide.

    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.

    Great experience. Tree came down in roof. Ascension took care of negotiating with the insurance company (that originally refused most of the cost) that ultimately covered the majority of an otherwise very expensive problem. Communications was excellent with updates on their behind the scenes conversations. Highly recommend. Took all the stress away.

    We had Chad and his crew install gutters on our house this past week. From the first call to installation was as simple and professional as it gets. Very knowledgeable in his profession whether it be gutters or roofs, which we will definitely have them do ours when we need it! I would definitely recommend him to any friend or family member cause I know they will be treated with the utmost respect and a price well worth it!! Thank you Chad and Ascension crew!!
