Was I ripped off by my property management?

[Grace Yang]

2 weeks ago, there was water leak in my rental in Austin. Last week, the property management company told me they have paid for me.

To plumber who found the leak and stop it: $3500

To remedy: $4700

It is a 1700 sqft one level sfh, I was told the leak from slab under pantry and the affected area is around 500 sqft.

Because the leak was from slab underground, my insurance doesn't cover and I have to pay every penny.

The question is: 1, I didn't get any pictures with the leak from slab

2, the tenants told me the plumber told him the leak was from bathroom somewhere above floor 

3, wasn't those two things too much? The plumber spent 5 hours.

Any BPer  know whether my concerns legit?

If I was ripped off, i definitely don't want to be ripped off by some unknown lawyers again, what could I do? Any suggestions?

Thank you so much!
