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

We specialize in the design, fabrication and installation of custom aluminum skylights, solariums, doors, welded aluminum windows and proprietary concealed frame windows. We also provide custom designed items such as aluminum louvered screens, hand rails, trellises and metal cladding.

Sun Valley is a licensed fabricator for the city of Los Angeles (Lic# 1637).  This enables us to provide a level of qualified structurally welded aluminum and steel fabrication unmatched by any other competitor without this qualification.

We are also an installing dealer for other window and door manufacturers, commercial glazing systems and other products. We can upgrade, modify or custom order products from our vendors to provide a level of customization that isn’t possible with ordinary dealers or single line manufacturers.

Our goal is to design and install products that deliver a lifetime of superior performance and enjoyment. We provide project specific detailed shop drawings that give you the ability to fully review everything. This assures you of 100% confidence in the outcome of our work, before we even begin.

With all of our resources, we can provide you with a complete package for a true single source solution to your project.

We look forward to hearing from you and welcome the opportunity to help make your project that much more exceptional.


“ I get to see many different skylight systems, and in my opinion, yours surpasses the rest in design, function and overall aesthetics.”

- Patrick Walsh, Sky Systems

“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, 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.”

- Gerry Vadeboncoeur, Project Manager, Carignan Construction

“I am happy to comment on the Sun Valley Windows. As a General Contractor, we have worked with Sun Valley for years with great results. SV's technical abilities in complex designs, quality installations and customer service have been the values that make for repeat business. SV's expansion into metal doors and windows was a natural progression. When it came to specifying skylights, doors and windows in my own home, I used the full SV line of products. This included some unusual combinations of doors & windows, including custom colors and detailed installation requirements. Ultimately the "one-stop" shopping experience yields greater efficiencies for the builder. We continue to use SV products wherever we have an opportunity to specify your products. And of course, Dave is just a damn good guy to work with!”

- George Minardos, Minardos Group

“The skylights you made for our house were installed yesterday, and we just wanted to let you know how pleased we are with them. Further, the roofer who installed them said he had never seen such solid, well-made skylights in the many years he has been installing them. Too often, people only write to contractors to complain. We wanted to make sure you know how much we appreciate your professionalism and fine quality.”

- Peter & Gail Dearing

“You are my favorite vendor.”

- Park Wellman, Architect, Zales Jewelry Corp

“We use Sun Valley Skylights because we can trust them to deliver a good product, on time and for a reasonable price and that is a really big deal in our business.”

- Dee Morris, Giroux Glass, Inc.

“How do I think Sun Valley compares to other skylight manufacturers? They're simply...the best!”

- Skip Danielson, Bayside Contractors

“We appreciate that the quality, price and delivery was as you said. It is very rare that things turn out better than expected.”

- W. Anthony Greg, Brewworks Hermosa Beach

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

- James Leslie, JNL Glass, Inc.
