Request an estimate based on the actual window count, dimensions, selected products, and installation scope. Different operating styles and changes to openings need separate review. Confirm removal, flashing, trim, repairs, and disposal in writing before comparing totals.

Confirm your window schedule with the City of Mountain View Building Division before ordering. Explain whether openings, dimensions, or operation will change. Ask which permit route, plans, energy documentation, and inspections apply to the project, and obtain the current fees rather than relying on a generic range.

A typical Mountain View home with 10 to 15 windows takes 1 to 2 days. Each window takes 45 to 90 minutes to remove, prep, install, insulate, flash, and trim. We install one window at a time and seal each opening before moving to the next, so your home is never left open to the elements.

Casement windows provide the best airflow and tightest seal for Mountain View's hot summers. Double-hung windows are a strong second choice for homes that rely on natural convection cooling. Picture windows work well in rooms where ventilation is not needed, offering the best energy efficiency ratings.
