“No Need for Competitive Bids”

This company rocks! We had bids from other vendors in SD for retrofitting an install from another company. The first company erroneously removed all the aluminum frames which resulted in leaks! US Window and Door came in and retrofitted the windows and they look amazing! I couldn’t be happier and this company is a stand out in San Diego and the highest marks for customer service!”

“Outstanding Company!”

The owner of this Company understands and practices quality work and customer service! He’s a owner that gets and stays involved with the various aspects of their service line. I thought the sales person, Joseph, was extremely knowledgeable about the products and the installers were great. I will definitely recommend them to anyone!”

“Finally a Breeze”

I wanted to replace some older vinyl block windows with a patio door to open up our front room and get some ventilation in the front of the house. Not all contractors call back. Martin and his company called back, knew what I was looking for and completed the job to my complete satisfaction. His crew was courteous, professional and cared about their work. I am completely satisfied and am having additional work done.”

We look forward to adding your 5-Star review.
