  • Ray, Hacienda Heights
    “I am happy to say that your team had met my criteria for fast and efficient installation of the Milgard windows and patio door. Your nearest competitor had earlier quoted me they will need 6-8 weeks to deliver and install the same items. You guys did it in 2 weeks. The actual installation took just a day. Awesome! I am glad that I have made the right choice in going with your company and Costco.”

Your installer exhibited a level of expertise, attention to detail, and professionalism that was nothing short of outstanding. The finished work is well-done and very attractive. I will be having additional window and door installations done in the near future, and I will definitely be using your company. Thank you again for the professionalism and quality of work done by your company. I will definitely recommend your company to my neighbors and friends in the future.”
