Is It Time to Replace Your Storefront Glass? Here’s How to Know

If you own a business in Minnesota, your storefront is your first impression — and in our tough Midwestern climate, that glass works extra hard. At Hallmark Glass, we know how vital clean, strong, and energy-efficient glass is for commercial buildings across cities like Minneapolis, St. Paul, and the greater Twin Cities metro area.

But how do you know when it’s time to replace your storefront glass? Here are five signs it might be time to call in the pros.

1. Foggy or Cloudy Glass Panels

If you see cloudy spots or fog between the panes, that’s a sign your insulated glass unit (IGU) seal has failed. No matter how many times you try to wipe it down — it’s not going away.

Solution: A full panel replacement is typically needed. Hallmark Glass can custom-cut insulated units to fit your exact storefront.

 2. Cracked, Chipped, or Scratched Storefront Glass

Minnesota winters are brutal, and repeated freeze-thaw cycles can make existing cracks worse. Damaged glass doesn’t just look bad — it also creates safety issues and weakens the structural integrity of your entrance.

Solution: If the damage is localized, we can replace just the affected panel. If it’s widespread or structural, we’ll recommend a full upgrade.

3. Cold Drafts or Hot Spots Inside Your Business

Noticing rising heating or cooling bills in your commercial space? Outdated glass and framing systems often leak air. New energy-efficient storefront glass can save hundreds annually on HVAC costs — especially in Minnesota’s extreme seasons.

Solution: Hallmark Glass installs low-emissivity (Low-E) glass with aluminum framing systems that seal tight and stay strong.

4. Water Leaks After Rain or Snow

Water shouldn’t be making its way into your business. If you're seeing water stains, puddles near entrances, or damp framing, your glass or seals may be compromised.

Solution: We’ll assess your entire system — sometimes it’s a simple recaulk, but often it means replacing failing components.

5. Your Storefront Looks Outdated

Whether you're in retail, dining, or professional services — appearance matters. If your storefront hasn’t been updated in over a decade, it may be time to refresh it with clear, modern glass and updated framing.

Solution: Our team can modernize your entire storefront with sleek glass, updated doors, and framing in your preferred finish (matte black, brushed aluminum, bronze, and more).
