Commercial Window Repair & Replacement
Office, Retail & Multi-Unit Properties
Broken seals, cracked panes, foggy IGUs, and full unit replacements for commercial buildings. We handle volume work, pull permits, and work around your business hours.
About This Service
Commercial window repair requires a different scope of work than residential. Office buildings, retail centers, apartment complexes, and industrial properties each have their own glazing systems — curtain wall assemblies, commercial aluminum frames, storefront-height windows, and multi-story IGU systems that are inaccessible without proper equipment and coordination.
As C-17 licensed glazing contractors, we're equipped to pull building permits, work within occupied commercial spaces, and coordinate with property management to minimize tenant disruption. Most commercial window failures fall into two categories: IGU seal failures (foggy, condensation between panes) and physical damage from impact, vandalism, or weather. Both are serviceable without replacing the entire window frame in most cases.
For office buildings and retail centers, we frequently work after-hours — scheduling repairs on evenings or weekends to avoid impacting tenant operations. For apartment complexes and multi-unit properties, we offer volume pricing and can coordinate phased repair programs that spread cost across a maintenance schedule. Low-E glass upgrades are available for Title 24 energy compliance when renovation permits are involved.
- IGU replacement: Fabricate and install new insulated glass units to existing frame dimensions — no frame replacement needed in most cases.
- Full window unit replacement: When frames are damaged, corroded, or incompatible with current code, we replace the complete assembly.
- Low-E upgrades: Upgrade existing clear glass to Low-E for energy efficiency and Title 24 compliance during permitted renovations.
- Volume property management programs: Ongoing maintenance agreements for apartment complexes and commercial portfolios.
For industrial properties — warehouses, manufacturing facilities, distribution centers — we handle large fixed-lite replacements, translucent panel systems, and wired glass replacement to current safety standards.

Our Process
We visit your property, measure all affected units, and assess whether IGU replacement or full frame replacement is appropriate. We note any permit requirements and after-hours constraints.
We provide an itemized quote with glass specifications. For occupied buildings, we coordinate an installation schedule that works around tenant hours and building management requirements.
IGUs are fabricated to your exact dimensions. Installation is performed efficiently to minimize open-window time, with weatherproof temporary covers used when needed during multi-day jobs.
Final walk-through with property manager or building owner. We provide written documentation for permit closeout, insurance files, or tenant records as needed.

5-Star Reviews on Yelp
Had some boutique mirrors done and the quality is great. Bryant was knowledgeable and professional. Highly recommend for any glass or mirror work.
The job was done well and professionally from start to finish. Our tenants were very happy with the results. Would definitely use again for future properties.
Responded quickly, arrived within days to measure, and finished ahead of schedule. The insulated tempered glass panels look perfect and the cleanup was thorough.
A friendly neighbor recommended them after seeing her beautiful bathroom. Was skeptical at first but the team was patient, elegant result, and they worked around my schedule perfectly.
I wasn't sure about going frameless at first but Frank and Bryant took the time to walk me through the design options. Solid work, looks exactly how I envisioned.
Got a mirror installed in the master bathroom and it turned out really nice. They offered 1/4-inch mirror, quality product, clean work. No issues at all.
