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

1
Site Assessment

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.

3
Fabrication & Installation

Frequently Asked Questions

Yes. Insulated glass unit (IGU) replacement is one of our most common commercial jobs. Foggy or failed seals in office windows are almost always an IGU failure — the outer frame and sash are typically reusable. We fabricate replacement IGUs to your existing unit dimensions and install them without disrupting the framing system.
Replacing glass in-kind (same size, same type) in an existing frame typically does not require a permit. However, changing window size, replacing the framing system, or adding Low-E coatings as part of a Title 24 energy compliance upgrade may require a permit. As C-17 licensed contractors, we handle permit coordination when required.
Yes. We regularly schedule commercial window work during evenings and weekends to avoid disrupting building tenants and operations. After-hours scheduling is available for office buildings, retail centers, and apartment complexes — call us to discuss your building's specific needs.
Low-E (low-emissivity) glass has a microscopically thin metallic coating that reduces heat transfer. California's Title 24 energy code requires Low-E glass in most new commercial window installations and major renovations. If you're doing a tenant improvement buildout or replacing windows as part of a permitted renovation, Low-E is likely required. We can spec the right coating for your situation.
Yes. Property managers with apartment complexes, commercial buildings, or retail centers can discuss volume pricing for ongoing window maintenance and replacement programs. We work with management companies on scheduled repair programs to keep costs predictable and minimize emergency call-outs.

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.
