Local housing stock
Building in Dover clusters in the mid 1970s: the median unit dates to 1976, with 67.2 percent finished before 1990. Frame housing on basements and crawlspaces predominates with a median build year of 1976, mixed with older mill-era stock along the river.
Climate & seasonal risk
October is the wettest month here at 4.79 inches, part of an annual 47.83 inches in the 1991–2020 normals from DURHAM 2 N, 2.4 miles off. The autumn maximum saturates ground just before the freeze, and near the tidal reach there is very little room below for it. Groundwater there moves with the tide as well as the season, so the wettest period arrives when capacity is already lowest.
Common moisture and mold problems in Dover
- A tidal river reach holding groundwater high across the lower parts of town
- Shallow ledge under the older streets, so frost lifts foundations that have nowhere to move but up
- Mill-era stock built on the lowest ground beside the river corridor
- Meltwater refreezing at cold eaves and backing under the shingle course above
