Referred through home warranty Old Republic.
Our faucet broke and we had planned on just buying a new one and replacing it until I realized we could utilize our home warranty to replace or fix it.
They called me on Friday and were available to come out the next day (Saturday) but I wasn't available until Monday. They gave me a 2 hour window and showed up in the window.
Turns out the sink was a quick and easy fix - my husband felt like an idiot for not looking at it himself after I told him it was broken. So it was probably a waste of money/a service call, but the tech did knock $10 off of the fee. So can't vouch for more complex service and fixes, but they called, showed up, and fixed our problem.
If anything goes wrong within 30 days they'll come back and fix it no charge.
