★★★★★
“The bifold doors completely changed our pool area. When they are open, we can see the whole backyard from inside, and the space feels connected instead of closed off. Cornerstone also installed the retractable screen, so we can enjoy the breeze without letting bugs in.”

“They replaced all 14 windows in less than three days. The crew kept the house clean, walked us through every window before leaving, and the house felt less drafty almost right away.”

“Our old patio door fought us every summer. The new sliding door opens with one hand, seals properly, and looks like it was always meant to be part of the house.”
— David R.
