Window replacement in Portola Valley
Portola Valley is rural by design: large wooded lots, low-key custom homes, and a town that wants the architecture to disappear into the oaks. The windows here are often big and view-driven, and the older ones leak heat into the cool evenings and let the dawn chill in. We fit energy-efficient glass that holds the warmth and keeps the view, in wood and clad to suit a ranch or a modern build set into the hillside.
The town's review and tree rules take some handling, and we take care of it: permit pulled, install to code, site left clean and the landscaping protected.
