Sun Valley Skylights + Windows + Doors is a premier manufacturing/installation company located in Los Angeles California since 1989.

We specialize in the design and fabrication of custom aluminum skylights and solariums.

Sun Valley has been a City of Los Angeles licensed fabricator since 2001 (Lic# 1637).  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 it’s beauty and functionality.

We are also an installing dealer for several window and door manufacturers, commercial glazing systems, skylights and other products. We work with other companies to be able to offer our customers a level of service and options that isn’t typical with ordinary dealers or single line manufacturers.

Our goal is to design and install products that deliver a lifetime of superior performance. We provide detailed shop drawings so you can have confidence in the outcome of our work, before we even begin.

With all of our resources, we can give you a complete package and a simplified single source solution for your project.

We look forward to hearing from you and welcome the opportunity to help make your project as exceptional as you intend it to be.


“We’ve worked with Sun Valley for almost two decades. During that time we’ve completed dozens of high end residential and commercial projects together. Dave, Abbi and their team consistently help us work out complex design and constructability issues which ensures a successful install. If there’s a problem, they stand behind their work. I can’t say enough. Brett Butler”

“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.   John D. Madden”

“The pool enclosure skylight (shown in the picture above) was an unusual challenge - controlled temperature and humidity inside and full sun exposure outside. The dome shape can be seen not only from inside but from the second floor balconies as well. Sun Valley met the challenge as they always do. I always specify Sun Valley. Gus Duffy”

- Gus Duffy, Architect

“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.”

“My crew was really amazed at how easily a project of this scope went together. You don't often find that today.”
