Window replacement in Mill Valley
Mill Valley sits in the redwoods at the foot of Mount Tam, where the fog and the canyon damp keep things cool and shady. That climate is hard on old windows, wood frames rot and warp, and single-pane glass runs with condensation. We replace them with energy-efficient windows in fiberglass or clad that handle the moisture, seal out the chill, and keep the woodsy character the town is known for, whether it's an older cottage or a hillside custom home.
We match the window to the house, pull the city permit, install to code, and clean up after.
