Within minutes, not hours. The best-documented research on this (a study of 5.7 million inbound leads at 400+ companies) found contact odds 100x higher when the callback happens within 5 minutes versus 30, and conversion odds roughly 8x higher within 5 minutes versus 6+ minutes. In our own audit, only 27.0% of 467 plumbing businesses even promise a response time on their website, so most of the market isn't clearing this bar today.
Plumbing has more genuine urgency than a lot of home-service trades, a burst pipe or an actively leaking water heater isn't something most homeowners are willing to wait on. That makes the 5-minute window closer to a real requirement than an aspirational target: a homeowner in that situation is often calling down a list, and whoever answers first tends to get the job.
"Respond" doesn't have to mean a completed conversation within 5 minutes, it means the lead knows someone's coming back to them that fast. An instant text confirmation the moment a form is submitted, followed by a call as soon as you're free, meets the research's own bar even if the full conversation happens a little later.
The gap between this bar and current practice is the real story here: 73.0% of the plumbing businesses we crawled make no explicit response-time promise at all, so a business that states one, and backs it with an actual instant alert, stands out by default, not because it's doing anything exotic.
