Frequently asked questions
Can the tide really affect a basement?
In the lower parts of town, yes. A tidal river holds groundwater up along its corridor, and that level moves with the tide as well as with the season. A basement there can be damp during a dry week for reasons unrelated to rainfall, which makes the pattern confusing at first.
Why does October rain matter more than July rain?
Because of what comes next. Ground saturated in autumn freezes with that water still in it, and frozen saturated soil expands and moves foundations. Summer rain evaporates and is forgotten; autumn rain becomes a structural input that lasts until the thaw.
What actually causes an ice dam?
Heat loss into the attic. It melts snow on the upper roof, the water runs to a cold eave and refreezes, and the ridge that forms backs water up under the shingles. The roof is where it shows, but the fix is insulation and air sealing below.
