French Drain or Regrade or Both?
Good morning. I am purchasing a house and due to water leaking into one sideof the cellar during hard rains, the owner agreed to install a french drain and/or regrade around that side of the property. Yesterday, the contractor installed the french drain. You can see where it was installed per the photo. My soon-to-be house is on the left.
Here are my questions:
(1) As you can see, the houses are closely set together. Though the contractor installed the french drain, he did not regrade. Given the amount of land available and the height of the foundation wall, is it possible for him to regrade?
(2) Even if possible, given the existence of the drain, is regrading necessary?
(3) Separately, as you can see from the photo it appears that he connected the downspout to the drainage system. Is this advisable?
