I had a character use a simple mend for great effect.
"The crushed crown is worth 329gp."
"I cast mending..."
(Carp) "The fixed crown is now worth 3,290gp."
Even mending can be useful.
It always depends on the DM, but if it is a static environment, you should be able to fix things with mending and make whole.
Imagine going to an ancient castle - could everything be restored?
A deteriorated silk dress in a drawer is worth zero, but would a mend make it worth 800gp again since it is almost a work of art? It wouldn't have many hps. As a DM, I would allow anything my players were able to utilize and be creative about. If they stop having fun, it's time for 1st levels in a world where nothing is damaged/broken.
