Positive Drainage Outside the House
During construction of all our new homes we install an angled cedar board on the window sill to divert any moisture to the outside of the house. Doing this does not allow any potential for water to accumulate on the window sill and run into the house. Moisture rarely finds its way onto the sill, however during a driving rain storms, moisture can get behind the window flashing and settle onto the sill. Our angled cedar installed on the sill is an extra precautionary step to prevent any water from entering the house.
