6+ Room New Window Service
I had one door and 10 windows installed and absolutely love them! Our salesman, Conor, ensured we got the best deal and throughly walked us through the process. If you interested in home refresh, I highly recommend Ameristar!

Sliding Door Installation
Needed a new sliding door since ours was old and constantly got stuck. We hired Ameristar and they were so professional. From booking the service, to purchasing the best sliding door, to the installation, everyone was so honest, polite and accommodating to the needs of my home. Now I have a sliding door that is quiet and opens and closes smoothly. Would definitely recommend hiring them if you need any new windows or sliding doors!!

6+ Room New Window Service
My husband and I needed new windows for our fixer-upper. And boy oh boy, did Ameristar deliver. The installers came ready to work and get the job done. The lead, Jared, was hardworking and stayed until the job was complete. Our sales rep, Conor, went above and beyond to ensure our satisfaction. And satisfied does not even come close to how we feel. We have had multiple people coming through our house, whether for personal or professional purposes, and we have gotten so many compliments and inquiries about our windows. Thank you, Ameristar.
Response from Ameristar Windows
"Thank you for your kind words and the 5-star review! We are thrilled you love your new windows and that Jared, Conor, and the team exceeded your expectations. Hearing that you are receiving so many compliments on your home is the ultimate reward. Thank you for choosing Ameristar Windows & Doors to work in your Riverside home!"

We chose Ameristar to replace our original, 20-year-old patio doors that were letting in heat and mosquitos. We compared quotes from a few local companies and Costco, but Ameristar was the only one with a reasonably priced door featuring a built-in doggie door. Sales rep Larry was knowledgeable and friendly. Scheduling and installation were quick, and the team did beautiful work. After 3 months, the doors are performing great. Highly recommend!

From start to finish my experience with Ameristar was 5 star. Martha at the office was friendly, professional, and helpful. Conor was excellent at explaining product and didn’t try to push me to purchase product. He was so nice, gracious and made me feel very comfortable. . The installation team did an excellent job, no mess inside or out. They were very accommodating to my request on what areas to work last ( pets). While they were installing windows a neighbor must have driven by and text me that the windows were beautiful. In appearance it has made a difference. I can also already tell a difference in insulation, my heater does not kick on as much. Pricing was excellent, when I told people the price they were very surprised and said it was an excellent deal. Thank you so much everyone at Ameristar for making a big home purchase so stress free.

Great job done. We just had the last window installed out of 25 that Ameristar has done for us over the last two years.

After retiring from the military, my family and I knew it was finally time to invest in upgrading our home in Lake Arrowhead, and replacing our windows was at the top of the list. We did a lot of searching before finding this company, and I can honestly say the experience exceeded every expectation we had. From the very beginning, Conor and his team made the entire process easy, comfortable, and stress-free. He came out to our home, took the time to explain everything clearly, and gave us a straightforward quote with absolutely no pressure or high-pressure sales tactics. That alone stood out to us because so many companies try to oversell or tell you what you want to hear just to close a deal. Conor was the complete opposite.. he was honest, professional, respectful, and genuine from start to finish. The installation itself was outstanding. The crew was punctual, hardworking, clean, and incredibly respectful of our home. The quality of the windows and workmanship completely transformed the look and feel of our house. Not only does our home look beautiful now, but it’s quieter, more energy efficient, and honestly feels brand new. As a retired military family, integrity and honesty mean everything to us, and this company delivered on both. It was truly an honor meeting Conor and working with a company that still believes in doing business the right way. If you’re considering replacing your windows, do yourself a favor and call them. You won’t regret it.
