Vinyl siding water problem
My house is about 18 years old with vinyl siding and builder's grade vinyl windows. The builders did not use Tyvek or any other moisture barrier, so the siding is right on the plywood. In heavy rain, I'm getting a lot of water beneath windows on the front of my house, and the plywood is very wet. Other parts of the house seem ok after rain (plywood under the windows is dry), it's just the front of the house that seems to be taking a real beating.
Does anyone have any ideas for fixes that would at least help this situation before I go as far as doing new siding/wrap/windows in the whole house? I live in eastern PA, so heavy rains are fairly common. Many thanks for any ideas.
