Our Process

Our process is built around clear communication and thorough documentation at every stage. Guided by our commitment to quality and service, we take the time to establish well-defined scopes and develop accurate measurements before fabrication begins. From there, our team applies expert craftsmanship throughout the fabrication process, followed by safe, professional installation and comprehensive testing. The result is a finished product that performs as intended and reflects a standard of quality.

Frequently Asked Questions

Storefront vs. curtain wall—what’s the difference?
Storefront systems are optimized for ground-level openings up to a couple stories and are typically faster, more economical installs. Curtain walls are engineered for multi-story façades and higher structural performance.
How long does a typical storefront project take?
After submittal approval and field verification, simpler projects can install in days; complex packages may be phased. Timelines vary by glass type and finish—ask us for current lead times.
Do you offer night or off-hour installs?
Yes, we are willing to work off-hours. We occasionally schedule off-hour work to reduce downtime for retail and quick-service-restaurant refreshes.
Can you meet brand standards for franchises?
Yes—profiles, finishes, hardware, and drive-thru window systems (e.g., Ready Access) can be matched to franchise specifications.
Do you service existing storefronts?
Absolutely. We repair doors and hardware, replace failed IGUs, correct weather seals, and recommend retrofit upgrades where they deliver value.
