Window replacement in Los Altos
Los Altos grew out of the valley's orchards into one of its most affluent towns, a place of ranch homes on big lots and newer custom houses, many with large windows facing the gardens. Old single-pane glass on these homes bakes the rooms through the warm summers and runs up the cooling bills. We upgrade to high-performance Low-E glass that performs without changing the open, light-filled feel the homes are built around.
We match the window to the house, pull the town permit, install to code, and leave the site clean.
