How can I trim metal window wells after lowering the grade around them?
Are you taking about one of these things?



If so, you might not want to cut it down. The lip should be a bit higher than the surrounding grade so that rainwater doesn't run in to the well.

If you don't cut it, you might be able to decorate it.



However, if you really want to cut it then you can use a reciprocating saw. If the metal is too thick, you might need to use a cut-off wheel on an angle grinder.
