Energy Efficient Options and Compliance

We prioritize energy efficiency and strict adherence to local regulations to ensure your commercial windows perform well and meet all legal requirements. Our products and services focus on reducing energy costs while maintaining safety and durability.

Energy-Efficient Windows

We offer a range of energy-efficient window solutions designed to reduce heating and cooling expenses. Features include double or triple-pane glass, low-emissivity (Low-E) coatings, and gas fills such as argon or krypton between panes. These elements improve insulation and minimize heat transfer.



Frames are available in high-performance materials like vinyl, fiberglass, and thermally broken aluminum to reduce thermal bridging. Selecting the right options depends on your building’s orientation, climate, and specific energy goals, which we assess thoroughly during consultation.

Building Code and Safety Compliance

All commercial window installations we handle comply with Pasadena’s local codes and national safety standards. This includes adherence to fire safety regulations, egress requirements, and structural performance criteria.


Our expertise ensures windows meet the California Energy Code and any zoning restrictions. Proper compliance prevents costly legal or insurance issues and guarantees occupant safety through tested durability and impact resistance.

Warranties and Maintenance Plans

We back our installations with comprehensive warranties covering both materials and workmanship. These warranties protect against defects and performance failures, offering peace of mind long after installation.



Additionally, we provide tailored maintenance plans that include inspection, cleaning, and seal checks to keep windows functioning optimally. Regular maintenance helps maintain energy efficiency and prolongs the lifespan of your commercial windows.

Our Installation Process

We follow a detailed and structured process to ensure every commercial window installation meets our standards for quality, efficiency, and safety. Each phase is carefully managed to provide accurate planning, professional execution, and thorough inspection.

1. Initial Consultation 


We begin every project with an on-site consultation to evaluate the building’s current window conditions. This includes measuring dimensions, assessing structural integrity, and identifying any potential challenges like weatherproofing or insulation concerns.


Our team discusses project goals with you, such as energy efficiency needs or aesthetic preferences. We document all findings and provide a clear explanation of installation options. This step is crucial for setting expectations and preparing for a smooth project timeline.


2. Project Design and Planning


Using information from the assessment, we develop a detailed project plan tailored to your building. This plan includes material selection, window types, and installation techniques that align with local building codes and energy standards.


We create a timeline that factors in delivery schedules, labor availability, and weather considerations. Our project managers coordinate with suppliers and subcontractors to ensure all resources are aligned before starting the installation.


3. Professional Installation 


Our certified installation teams handle the windows with care, prioritizing precision and durability. They follow manufacturer guidelines and use specialized equipment for fitting, sealing, and securing each window frame.


Safety protocols are enforced on site, including the use of personal protective equipment and proper scaffolding or lifts. We also minimize disruption to your daily operations by scheduling work phases efficiently and maintaining a clean work area throughout.


4. Post-Installation Inspection


After installation, we conduct a comprehensive inspection to verify that all windows are properly sealed, aligned, and functional. This includes checking for air or water leaks and testing locks and hardware.


We provide you with a detailed report of this inspection and address any adjustments needed. Our goal is to ensure that the installation meets our quality standards and your satisfaction before we finalize the project.
