Hiring guide

## Before you sign with a Largo company

- **Check the license.** Ask for the license number and look it up on the state's licensing portal; it takes a minute.
- **Ask who pulls the permit.** If the job needs one, the company should apply for it and include the fee in the quote.
- **Compare the same scope.** Ask every company to price the same work, materials and extras so the numbers line up.
- **Tie payments to stages.** Be wary of large deposits before work starts.
- **Get the warranty in writing.** What it covers, for how long, and who you call.
