Is this site the contractor, or just a go-between?
Just a go-between -- an independent provider handles the actual work.
Can you guarantee same-day availability?
No -- that depends entirely on the provider's own schedule.
Can damage be judged from photos alone?
Not reliably -- hidden damage usually calls for someone on-site.
Should I get quotes from more than one provider?
If there's no emergency, yes -- it's worth comparing written scopes.
Who verifies a provider's license and insurance?
The homeowner does -- ask for documentation up front.
