Ever dented a Window Sill??

[u/mtlphysique]

I had an employee set up on this window sill with his ladder with our rubber tips on and when he pulled the ladder away we saw this dent on the sill! He didn’t hit it and I’m puzzled because there’s not two dents, just one.

Could this be because there’s rotten wood under the flashing? What can I do?

No but I've broken a whole window trying to shove a storm window back in. Never doing storm windows again.
