What the houses here are like

Napa's median house dates to 1976 and about six in ten predate 1980. Summer heat here is real, and single-pane or early dual-pane glass on a west wall is the difference between a room you can use in August and one you cannot. Where a house has been through a remodel, we match the new openings rather than force everything back to one style.

  • Median year built: 1976
  • Built before 1980: 60 percent
  • Built before 1960: 23 percent
  • Owner-occupied: 67 percent
  • Homes sold in the last year: 529

Housing figures from the Census American Community Survey 2023 and Redfin closed sales, for ZIP 94558.

What people here call us about

Napa calls in the summer. Once a west-facing room becomes unusable in August the phone rings. It is also the busiest resale market on our list, 529 homes sold in the last twelve months, so a good share of the calls come from people who bought a house that came with 1970s glass and found out in their first summer.

What we do in Napa

  • New window and door installation
  • Replacing failed dual-pane units, the ones fogged between the panes
  • Sliding windows and patio doors that no longer roll or lock
  • Whole-house replacement in standard tract sizes, which keeps the lead time short
  • Entry, patio and French doors, in Andersen, Milgard and Simonton
