What the houses here are like
Concord's median house dates to 1974 and about two thirds predate 1980. The common job here is a 1970s tract house where the aluminum frames sweat in winter and the sliders no longer lock. Concord summers are hot, so the glass package matters as much as the frame.
- Median year built: 1974
- Built before 1980: 68 percent
- Built before 1960: 17 percent
- Owner-occupied: 73 percent
- Homes sold in the last year: 430

What people here call us about
Concord calls arrive in two flavours. Winter brings the aluminum frames that sweat and drip onto the sill, summer brings the rooms that will not cool down. Both are the same 1970s window. Sliders that no longer lock are the third recurring item, and that one tends to get dealt with fastest, because it is a security question rather than a comfort one.
