Hit my capacity ceiling as a solo operator — when did you know it was time to hire?

It's time to hire when things start falling through the cracks because of lack of labor, when you can't follow up on new leads or estimates in a timely manner and when you're not accepting new business because you have no more room on your schedule. It's scary to onboard new people and you will go through a lot of bad hires to find one good person but there's only so much you can grow white knuckling your way through the season.
