A properly drained window well is the fix: the well gets a gravel base and a drain that ties into the perimeter drainage or daylights away from the foundation, plus a cover. We also rebuild and seal the window. This is common with finished-basement egress windows.
More detail
A window well that fills with water turns the basement window into a direct entry point, and it is a frequent Cincinnati problem, especially for below-grade egress windows serving finished basement bedrooms. The cause is almost always a well with no working drainage: surface runoff and roof water collect in the well faster than the soil can absorb it, the well fills like a bucket, and water pushes through and over the window. The fix is to make the well drain. The crew excavates the well, installs a gravel base and a vertical drain that connects either to the interior perimeter drainage system or to a daylight or storm-appropriate outlet that carries water away from the foundation, reseats and seals the window itself, and adds a clear well cover that keeps rain and debris out while still allowing egress and light. For homes that also have hydrostatic seepage elsewhere, tying the window-well drain into the same interior drainage and sump system is efficient and reliable. This work overlaps directly with egress requirements: a finished basement bedroom in Ohio requires a code-compliant egress window for safe exit, and Cincinnati resale inspections check for it, so a window-well-drainage job is often combined with an egress-window install. The crew handles both together, sizing the well and window to code while solving the flooding. The common shortcut to avoid is simply bailing or pumping the well after storms, or adding a cover without adding drainage; the cover alone reduces rain entering the well but does nothing about the surface water and groundwater that pools there, so the well keeps flooding until it can actually drain.
