How long do commercial windows last in Minnesota?

Commercial window systems typically last 25–40+ years depending on framing and glazing. Upgrading to triple-pane or low-E argon-filled units can dramatically cut HVAC costs while improving tenant comfort year-round.

Which commercial window system fits your building?

Aluminum Storefront
Lifespan
30–40 years
Resistance
Excellent — engineered for traffic

from $20,000+

Retail, restaurants, offices.

Curtainwall Glazing
Lifespan
30–50 years
Resistance
Very high — structural glazing
Starting Investment
from $60,000+

Mid-rise & flagship facades.

Commercial Replacement Windows
Lifespan
25–35 years
Resistance
High — triple-pane options
Starting Investment

Multifamily, offices, hospitality.

Starting investments are general guidance for typical Minnesota homes and vary by size, complexity, accessibility, and material selection. Every project receives a free, no-obligation written quote.

How do you replace storefront or curtainwall glazing without closing the business?

We replace commercial glazing opening by opening or bay by bay, temporarily securing each opening before moving to the next so the building envelope is never left exposed overnight. For active storefronts and restaurants, work is scheduled before or after business hours where the frame allows, and larger curtainwall sections are staged with protective barriers so customers and staff can still move through the space safely.

On multifamily and office buildings we sequence unit-by-unit or floor-by-floor so only a small number of openings are open at any time.

What's the difference between storefront, curtainwall, and standard commercial replacement windows?

Storefront systems are ground-floor aluminum framing built for retail and restaurant entries, designed for durability under daily traffic rather than thermal performance. Curtainwall is a larger structural glazing system used on mid-rise facades where the glass itself carries wind load, typically specified by an architect for new construction or major renovations. Standard commercial replacement windows are sized units for offices, multifamily, and hospitality buildings that need better energy performance without a full structural facade change.

Choosing the right category comes down to what's already in the wall — we assess your existing framing before recommending a system rather than defaulting to the highest-margin option.

Do new commercial windows actually lower HVAC costs?

Upgrading old single-pane or failed-seal commercial windows to low-E, argon-filled double- or triple-pane units meaningfully reduces heating and cooling loads, particularly on buildings with large glazed elevations. The savings are most significant on offices, hospitality, and retail properties where glass makes up a large share of the exterior wall area.

We size the upgrade to your building's actual glazing area and current HVAC performance rather than promising a flat percentage that doesn't hold up building to building.

How does the project run?

  1. 01

    Facility walk & measure

    Every opening or bay is measured and checked for frame condition, water intrusion, and energy-code compliance.

  2. 02

    System proposal

    Line-item pricing by opening across storefront, curtainwall, or standard replacement options, with financing available.

  3. 03

    Custom fabrication

    Units are built to your exact openings; typical lead time is four to eight weeks depending on system and glazing.

  4. 04

    Phased installation

    Opening-by-opening or bay-by-bay sequencing scheduled around business hours, tenants, or occupants.

  5. 05

    Walkthrough & warranty

    Every opening is operated and inspected with your team before we leave, and warranties are registered on the spot.

Frequently asked questions

Can commercial windows be installed in Minnesota winter?

Yes, one opening at a time with temporary weather protection between removal and installation so the interior stays conditioned. Larger curtainwall projects are more weather-dependent and are scheduled accordingly.

How long does a storefront replacement take?

A typical storefront entry is replaced in one to three days. Full-building curtainwall or multi-floor projects are sequenced over several weeks to limit disruption.

Does insurance cover broken or hail-damaged commercial glass?

Wind- and hail-broken glazing is typically covered under commercial property policies, minus the deductible. Fogged seals from normal aging are a maintenance item, and we'll tell you which one applies.

Do you handle energy-code compliance documentation?

Yes. We size glazing to meet current Minnesota commercial energy code requirements and provide the documentation your building permit or tenant improvement process requires.

What warranty comes with commercial window replacement?

You receive the manufacturer's glass and frame warranty plus the MBE Lifetime Workmanship Warranty on our installation and flashing.
