Send contractor emails around 6 to 7 PM, not at noon. Contractors take lunch breaks at midday and check messages at the end of their workday, when they're more likely to reply.
order to do that, you're going to need to know a little bit about the business. My dad is a contractor. I know that you don't want to email him at noon. That's his one time to sit down and get a little break. But I do know from his business and the way that his day kind of rolls, probably you're going to be more than likely going to get a reply to an email, say, at 6 or 7 o'clock at night.
