How a slope changes a water loss

On a flat lot, rain and snowmelt spread out. On a hillside, they travel. A house on the uphill side of a Green Mountain street can collect water draining from the yards above it, right against its rear foundation wall, which is often the buried back wall of a walkout basement. When gutters overflow or the soil slopes toward the house, that wall takes the hit.

A walkout lower level behaves differently from a fully buried basement. The front of the room sits at grade with a door or big windows; the back sits underground. Trouble usually starts along that buried back wall and in the corners where it meets the side walls, then spreads across the floor toward the walkout door.

Inside, houses from this era mostly have copper supply lines and have passed the age when original water heaters, washer boxes and shower valves start failing. Many owners also finished their own basements, sometimes with drywall right against the foundation and little thought about where water would go.

Green Mountain owner checklist

  • Walk the uphill side of the house in a heavy rain and watch where the water goes.
  • Make sure retaining walls have drainage and the weep holes aren't clogged.
  • Extend the uphill downspouts well away from the foundation.
  • Check the buried back wall of a finished walkout for stains, swollen baseboard or a musty smell.
  • Find out which water and sanitation district serves your street, and save its number.
