Vicinity of Lakeshore Rd in Dunnville

We have an older rental house in Cayuga with a damp basement. After that last rain over Thanksgiving weekend, water came in down the wall and up through the floor. Both of these were new places for water to come in. There are a few cracks in the basement that we should have had fixed years ago.

Vicinity of Lighthouse Drive in Dunnville

We just purchased the home and last weekend was the first time we were home when it rained. Unsure where water is coming from. I am only available at the property on Saturdays or Mondays.
