About
Whetstone started with old radiators in Windham County farmhouses and grew into new floors.
Most houses here heat with water already: cast iron in the older ones, baseboard in the ones from the seventies. Radiant floors are the same idea carried into the floor, and they work best when someone draws them before the floor goes in.
That is the one thing we do. We design radiant and hydronic systems, install them, and look after them each year.

The people
Seven of us in all: Mya, Jared, four installers and an office manager.
