Q&A for How to Install a Window Well

The distance between the top of window to the top of well can vary. However, there should be a gap between the bottom of the siding and the top of the well. The top of the well should sit a few inches above the ground.

If the steel wells are rusted out, it is most likely that the bolts holding it to the wall are rusted into the wall. The best solution is to raise the new well above the old bolt holes, unless the new window well has different hole locations.

The gravel should be 4" below the window well to allow rain water to make it to the drain.

I used 1/4" x1 3/4" flathead tapcons spaced 6" apart in the valleys of the galvanized steel window well. They're very secure. I painted the wall with a foundation coating first.

No. I would make sure it is straight in comparison to the bottom edge of the siding on your house (which is probably pretty close to level anyways). Level doesn't matter as much as making sure it doesn't LOOK crooked.
