Our Work

What We Do

LGD specializes in providing comprehensive contract glazing solutions for commercial buildings. Our expertise covers everything from high-performance curtainwall systems on mid-rise buildings to aluminum storefronts, interior office partitions, and fully automated glass doors. We also handle demolition of old systems and replacement of aged or inefficient glazing. 

Unlike basic installers, our team participates in project planning and collaborates with design and construction teams to help select glazing systems that perform reliably and align with the project’s vision. When needed, we provide shop drawings, hardware schedules, and engineering documentation. Whether you need storefronts for a retail center or complex glazing for a public school, we’re prepared to handle every technical aspect. 

Our work supports a wide range of performance criteria, including Title 24 compliance, energy efficiency, noise reduction, seismic movement, and ADA accessibility. We are regularly brought into projects where advanced coordination and proper documentation are essential to meet inspection, budget, and timeline requirements.

Glazing Options

Performance-Driven Glazing Options

We provide a wide range of performance glazing types based on the specific needs of the building and the environment. This includes tempered safety glass, laminated glass for impact resistance, and insulated units that improve building envelope performance. 

Low-emissivity coatings are available for added solar control, and we offer custom glass types such as low-iron, frosted, or tinted glazing to match the project’s visual goals. Framing systems can be configured to meet wind-load requirements, seismic activity thresholds, and energy code mandates. All systems are sourced from trusted manufacturers with proven field performance. 

Whether you’re building in a coastal environment, urban center, or high-traffic commercial area, LGD delivers contract glazing solutions that balance appearance, functionality, and code compliance. 

Why Choose Us

Why Contractors Choose LGD

Contractors across Southern California rely on LGD because we combine technical ability with job site professionalism. We don’t just install what’s given to us, we actively support the project with insight, problem-solving, and documentation that helps things move forward. Many of our clients bring us in during pre-construction so we can help flag issues early, suggest system changes, and provide accurate timelines for ordering and fabrication. During construction, our field teams coordinate with other trades and adapt to jobsite conditions quickly. That level of engagement helps projects stay on time and within scope. We are fully equipped to meet public sector documentation standards, including certified payroll, OCIP and CCIP tracking, PLA/PSA contract support, and safety reporting. If your job requires detailed closeout paperwork or third-party inspections, we’re ready to deliver what’s needed.

Our Certifications

LGD is a NACC-certified contractor, which means we’ve been independently evaluated for quality management, operational consistency, and workforce training. Every installer on our team has completed OSHA training and follows proven safety practices. Our internal safety program is enforced on every project. From the start of mobilization to the end of install, we follow procedures that minimize risk and protect everyone on site.

Contract Glazing That Works

At LGD, we take pride in offering contract glazing services that go beyond just showing up and hanging glass. We focus on building long-term partnerships by doing the job right the first time. That means thoughtful coordination, responsive project support, and lasting installations built to perform for years. We understand that every piece of glass plays a role in a building’s function, safety, and long-term value. That’s why we treat every opening, every seal, and every system with the attention it deserves.
