"Dimitar and his staff were all so professional, considerate and precise in everything they did for me! The retrofit of the new bay to the overhead eaves and house lines looks like it was originally planned that way."

Ronald W. from Foster City

Abstract Windows were prompt, precise and affordable. The work they did at our property was great. It is amazing how upgrading windows makes such a difference in property value and the look of our home. I would definitely recommend Abstract windows to others."

Lizette B. from Campbell

"Dimitar installed the windows per the structural engineer's drawings and kept safety of the structure his first priority. You can trust him to give you his honest opinion every step of the way to ensure you got what you needed."
