"Today the temperature was 103 and boy did we notice a huge difference in the inside temp of the house, all due to the energy efficiency of the windows! I must say, being in the development business for 30 years, these windows, the locks, the screens, the installation were all superior to what I had imaged."

RANCHO BERNARDO

"As you know, our home in Rancho Bernardo that Sierra Window Concepts helped us upgrade with your terrific dual pane window products four or five years ago was in the middle of the devastating fire that swept through San Diego in October of last year. A significant portion of the homes in the neighborhood were burned to the ground, but luckily ours was spared. I believe one of the reasons, if not the primary reason, was the extra thick Sierra Windows we had installed. The home to the west of us was completely burned down. Although we had to replace four of our windows on that side of the house, only the outer pane of the glass broke, thereby protecting our dwelling from significant damage. I believe that the sturdiness of the inner pane prevented the fire from entering our house and causing significant damage."
Jim F., Rancho Bernardo

"I wanted to let you know how happy I am with Sierra Windows. I live in Rancho Bernardo and had to be evacuated during the fires. When I returned home 4 days after leaving my home, it was still there. The inside of my home was the same as I left it. My Sierra Windows kept all the smoke and ash out of my home and I am so glad I had them installed 5 years ago. Thank you again for your marvelous windows."
Edith, Rancho Bernardo

David & Janice, Temecula, Riverside County

SAN DIEGO

"This letter is to let you know that we are so happy with our new windows and are so thankful that we chose Sierra Windows to do the job. The process was fantastic from start to finish. I can't believe the excellent quality at such a discounted price. The installers were professional and did excellent work. There are no words to describe just how grateful we are. We received a much higher quality product than that we had expected. The service was much better then we expected. We saved for 9 years for our windows and they are even nicer then we had expected!!"
