Commercial Door
Replacement

G2 Construction installs and replaces commercial entry doors, hollow-metal openings and storefront door systems for retail centers, office buildings, medical suites, warehouses and multi-tenant properties across Northern Colorado. As a full-service commercial general contractor, we handle the framing, hardware and finish work most door vendors can't, and we schedule around your operating hours.

Commercial building entry with heavy-duty door system

Entry Systems, Hardware & Fire-Rated Openings

Commercial openings take abuse residential products were never built for. We specify and install hollow-metal and aluminum entry doors, storefront door leaves, panic and exit devices, closers, continuous hinges and ADA-compliant thresholds, all sized to your building and tenant requirements.

Because G2 is a licensed commercial general contractor, we can also reframe openings, correct structural headers, repair damaged substrate and rebuild the surrounding wall in the same mobilization. One contractor, one schedule, one warranty.

From single-tenant storefronts to multi-building office parks and industrial facilities, we deliver door packages that meet commercial code, pass inspection and stand up to years of daily use.

Offices & Medical Suites

Tenant-finish door packages, fire-rated openings, closers and access-control-ready frames throughout the suite.

Hollow-metal frames, insulated service doors and dock openings built for warehouse and light-industrial facilities.

Every commercial door replacement we complete is planned so your openings:

Meet ADA, egress, fire-rating and life-safety standards
Pass commercial building code and local inspection
Handle high daily traffic with commercial hardware and closers
Install on nights, weekends or phased schedules to keep you open

Built for Commercial Duty

Hollow-metal and aluminum entry doors, panic hardware, closers and continuous hinges specified for daily commercial traffic, not residential-grade hardware.

Fully licensed and insured across the Colorado Front Range, with the documentation your property or tenant agreement requires.

Closed doors cost revenue. We phase commercial door replacement by entrance, suite or after-hours window, secure every opening overnight, keep entrances ADA-accessible during work, and maintain clean, protected paths for your staff and customers from mobilization through final inspection.
