About Us

who we are

Since our inception in 1989, Sun Valley has worked to consistently deliver the finest possible results for our customers.


Our philosophy is simple: we design our systems to deliver a lifetime of superior performance and enjoyment.


The scope of our work extends to projects of any size or requirement.  We can either build to your specifications or provide you with design assistance.  We use state of the art computer aided design, engineering and manufacturing to produce your project accurately and efficiently. We also provide professional installation with our in-house crews or through qualified dealers/installers.


We welcome the opportunity to help make your project that much more exceptional.

City of L.A. Fabricators License # 1637

Our firm holds a City of Los Angeles fabricators license. This enables us to provide pre-qualified structurally welded aluminum and steel products which eliminates the need for unsightly bolted together frames. Our work is famous for its beauty and functionality.

Professional Qualifications

Our services include field measurements, expert design solutions, professional Shop Drawings, in-house fabrication and a professional installation. Even though this level of service is a tremendous responsibility, we know it’s the best way to get the job done right.

Our skylight systems are designed to be mechanically waterproof, in addition to using premium quality extruded gaskets and structural silicone. Any moisture which may penetrate the primary exterior seals will be controlled and drained out of the frame system through the interior gutter.

We also offer 8 different skylight systems that can span up to 24 feet. Typical connections and assemblies are fully welded to provide strength and durability. Large site-assembled units are designed with welded components and blind connections whenever possible, producing a clean aesthetic appearance. Our skylight systems can also accommodate any type of glazing material.

Our installation crew consists of experienced professionals with extensive training. We have the proper equipment, a working OSHA approved safety program and the proper licenses and insurance. We do most of the related flashing and water-proofing as part of the installation process and offer a 10-Year Leak Warranty on all of our installations.

"I have worked with SVS for almost 30 years have never been disappointed and always very pleased and amazed at the quality and service. I wish all the companies I work with had the integrity, knowledge, options, details, quality of workmanship, design capabilities and service that SVS has demonstrated over the years. There is no other skylight company I would use."

“I'm writing this letter to personally thank you and your team for doing such a great job on our East Mountain Drive project. I have been in the business my entire life and Sun Valley is, by far, among the best subcontractors we have worked alongside. As you know, this has been a very challenging project and we appreciate your company's ability to "think outside the box". From assisting us in the design phase through installation, your crew has been professional and top notch. I look forward to our next venture together as you have earned a spot on our team. Feel free to use us as a reference any time. Thank you again.”

“I wanted to take a moment to tell you about my work experience with Sun Valley on a recently completed window project. This was the first time that we have worked with them and this project had a very demanding architect. I am pleased to say that Sun Valley came through in an exceptionally professional manner. David Witty was very gracious through the numerous changes, requests for design input, etc. The final product was delivered on time, on budget with a beautiful result.”
