Most Trusted Window Replacement Company In Pasadena
"We are extremely happy with every aspect of Longhorn Windows from Eli’s sales visit where he explained everything and gave us a very competitive price to the installation days and the finished product. The installers were professional, competent and knowledgeable. They removed the old and installed the new 38 windows with absolutely no mess or damage in just two days! Every other company told us it was impossible to manufacture the small, oddly shaped, ornamental windows we have but Eli assured us it was not a problem and he was not wrong. They’re beautiful and we couldn’t be happier. Not only are they aesthetically pleasing but they’re so practical. We’ve noticed an immediate difference in reduced AC usage. The house is markedly cooler. The house cools quickly once it does come on and stays cooler for longer. Wish we’d done this years ago. We HIGHLY RECOMMEND Longhorn if you’re looking to update your old, inefficient windows."

"I really don’t know where to begin so let’s just start at the beginning. I needed new Windows and Longhorn helped point me in the direction of the best financing and the buying process was super smooth and affordable. Second the office staff is attentive, courteous and informative. The staff called me when my windows came In (which by the way they came in way faster then expected) and then gave me a date that worked for me. And she gave me a courtesy call when the installers were on their way. Now on to the installation. THESE GUYS ARE AMAZING. CLEAN. COURTEOUS. I cannot say enough about them. They were quick. But not because they were rushing. But because they are just so good at their job. And they cleaned and vacuumed after the job was done. I would HIGHLY recommend Longhorn Windows. They are reputable and affordable and I am so happy with my purchase."

Highly recommend Eli and Longhorn Windows for top-notch service and quality installation!"
