No, no, no, no, Maggie. The faulty basement window will be removed (think rotten tooth) and the hole will be closed — bricked up, to be precise. That has to be done inside the house. The next and more drastic part of the project involves digging along the foundation to clear the drainage tile and build a proper well in front of the surviving window, and waterproofing the outside of the concrete foundation. That will involve much Sturm und Drang, including taking up and relaying about half the patio.

All of it will be very expensive.
