Garage Repair Cost question

[Mel Park]

Hello all..... I have a few TH's -  metro areas.  Use a property manager that I feel the relationship is good, everything is orderly - and while it comes at a cost, it's truly as passive as a non-paper investment can get.  They recently did some work on the garage. I'm putting the charges here - curious if folks here think it's a little high, or reasonable.

Total is $467.00

Appreciate any thoughts - I don't have more specifics than this. I don't want to Monday morning Qback every expense - first off I don't have the knowledge and also, it's tough to tell someone "handle it" - -and then want to look over the shoulder for every move.  If I'm maying a bit more - fine. I just want to make sure it isn't blatant fleece-age.
