How We Got Started

I chose to work in this industry because John Kain my Father saw a need in riverside County for the tattered and ragged canvas awnings that were always in need of repair or replacement. He saw thsi unmet need as a challenge to create a way to modify the existing framework to accept an aluminum frame awning that he fabricated. It was our intro into the specialty aspect of home remodeling. Today the same family, same company exists and is known for their Sun Room additions and Bath remodel or replacement projects!.

We started in this industry in 1982.

We describe our business as Family owned and operated

Why has Sun Boss Corporation survived all these years when so many companies have failed?

Sun Boss has a commitment to the client, our family of customers has always kept us strong!

Review by in Hemet, CA
We wanted to extend and screen enclose our patio so we could better enjoy sitting outside without those annoying flies pestering us. We decided to hire Sun Boss because of their longevity and reputation in the industry. David Kain from Sun Boss was very thorough in presenting all the options to us. David was also very helpful meeting with our HOA design review committee to offer extension design options that could be approved in our community. Thanks to David's efforts, we did get approval. Our patio roof was extended six feet by twenty-four feet. All the material used is of high quality construction and an attractive appeal sandstone color that coordinated naturally with the color of our house. Donn Stanley from Sun Boss was very dependable. He kept us updated throughout the project in coordinating material delivery, the workload, permits and invoices. David Shelby, Sun Boss installer, was absolutely a true professional and very skilled in the construction of our custom project. He cleaned up at the end of each day (seven days total). David was very meticulous making sure every detail was done correctly. He would always stop to answer any concerns we had during the installation. There were a few minor issues that had to be corrected, however Sun Boss and David Shelby did not hesitate to come back and make it right. We measure a good company not only by a quality product, but also by how well they respond to issues or concerns. Sun Boss definitely provided both with excellent customer service. We are really enjoying our patio now. And, with the positive experience we had, can highly recommend Sun Boss.
Response by Sun Boss Corp.: Thank you so much for taking the time to share your experience, I know you all will love your new indoor outdoor screened porch!! Thanks, David

Review by in Beaumont, CA
My involvement with Sun Boss began with Erik, who came to my home to discuss the available products with me. He told me about the quality materials, history of the company, and the excellent people behind the construction of the rooms. He wasn't wrong. There were no high-pressure sales tactics. He didn't need it. I asked questions and he answered. I signed the contract and gave him the deposit that evening and have no regrets. After thinking about it overnight, I decided on a slightly larger room, so I called Erik. He and Donn Stanley came to my home with a new contract a day or two later. They also measured the yard and house while there. The estimated start date for my project was December. Lucky for me, in November, Donn emailed and asked if it was ok to start soon. Perfect! Well, it's a few days before Christmas and George and Glen just finished my room a little while ago. I love it! George and Glen were always prompt and professional. I felt that they cared about doing a good job on my room and I appreciated that. I never had the impression that they were rushing through the construction, and in a hurry to move to the next project. Their work was outstanding! Kirk did an amazing job on the painting, and float and texture of the exterior house wall. It looks like it was part of the house when it was built several years ago. It's pretty! As they worked, everyone involved left the yard and room clean and organized before leaving for the day. My experience with Sun Boss Corp. has been one that I will repeat to my friends and family. Thank you, Donn, Glenn, and George for answering my numerous questions throughout this process. I'm anxious to get the window treatments and flooring completed soon! We plan to use the room as a reading/writing, exercise, dining, and relaxation room. I'm sure my daughter will also enjoy using it to draw and paint. I don't know the names of the others involved with my room before and during construction, but would like to thank them as well. Thank you, Sun Boss!
Response by Sun Boss Corp.: Danielle thank you so much for taking time to tell us about your experience!!! The pleasure was all ours, hope you are enjoying your room. David Sun Boss

Review by in Cathedral City, CA
They dug up a large section of my yard to use as a base for the concrete slab, replacing it and regrading will be at my expense. They are very quick to raise the price for unforseen problems but unwilling to credit the full amount of a canceled portion of the project. If you are in the Palm Springs area be aware that they are NOT local. All subs are from Riverside. I should have stuck to Craigslist for a lower price from someone local.
Response by Sun Boss Corp.: Fred I am so sorry for your frustration, we always had local subs but we struggled with quality and stability, so we do use our same subs throughout both counties. I would like you to call me at the office so I can understand your frustrations as we always attempt to be very clear what you are charged for and what you are not. I am sorry for the delay in responding. Thank you David Kain
