Case studies/The 5-minute rule
Lead response

The 5-minute rule that still wins jobs in 2026.

Every serious sales study since 2007 says the same thing. Call a new inbound lead inside 5 minutes, and you are 100 times more likely to make contact than at 30 minutes. Most contractors don't come close. The ones that do eat their competitors' lunch for breakfast.

The short version
100×

drop in contact odds between 5 minutes and 30 minutes (MIT / Oldroyd)

21×

drop in qualification odds across the same window

$90.92

average cost per lead for home service paid search in 2025 (LocaliQ)

20,000+

new clients per month at the top of the home service market (A1 Garage Door)

A homeowner fills out a form on your site. Their water heater is making the noise. You have about five minutes before that same homeowner fills out the form on your top three competitors' sites too.

This is not a new idea. It is the oldest finding in inbound sales. And after 15 years of everyone knowing about it, almost every home service contractor still responds in hours, not minutes.

The study every good sales manager cites

In 2007, Dr. James Oldroyd (then at MIT, later Kellogg and BYU) ran a study on lead response. He was hired to figure out why some companies converted inbound leads at huge multiples of others. The answer turned out to be embarrassingly simple:

The odds of contacting a lead dropped by 100 times at 30 minutes compared to 5 minutes. The odds of qualifying dropped by 21 times. 1

Harvard Business Review wrote it up in March 2011. 2 Every sales training deck on the planet has stolen that chart since. Contractors are the people it still applies to hardest, and the people who use it least.

How bad is it in the trades today

Most home service shops respond to a web form lead within several hours. Some take until the next business day. Some never reply at all because the form email went to a Gmail inbox nobody reads.

That would be fine if the homeowner was waiting patiently for you. They are not. They already filled out two other forms. They already called the shop that came up first in Google Local Services. The second person to contact a hot lead is usually the one who loses.

Do you want to know what the reigning champion of home service sales is? It is not the biggest truck, it is not the best price, it is not the prettiest website. It is picking up the phone first.

What the best-run shops actually do

Tommy Mello took A1 Garage Door Service from two trucks and $50,000 of personal debt in 2010 to more than $200 million in revenue, 20,000 new clients a month, and roughly 26,000 calls a month, according to interviews published by Arkona and Owned & Operated. 3 He talks constantly about one thing: measurement. Every CSR has a booking-rate scorecard. Every lead source has a response-time SLA. Every call has a desired outcome written down before the CSR picks up.

John Wilson at The Wilson Companies in Northeast Ohio grew a $1 million family plumbing shop into a $26 million multi-trade operator in roughly seven years, rolling up five acquisitions along the way. 4 He has publicly talked about investing in digital lead gen early, then building the dispatch and response infrastructure to actually convert those leads.

The pattern across Mello, Wilson, Peterman Brothers, and every other shop that has publicly broken $50M in the last decade is the same three things on the inbound side:

  • A response-time SLA per channel. Call back within 5 minutes. Reply to web forms within 5 minutes during business hours. SMS within 1 minute.
  • A CSR scorecard that sees every lead. Not just calls. Web forms, Google Local Services leads, Facebook form-fills, chat widget conversations. One scoreboard.
  • A post-mortem on every unconverted lead. Not blame. Pattern recognition. If the same lead source keeps not converting, something is broken. If the same CSR keeps dropping them, coach them or move them.

Why most contractors can't do this

Because the leads live in four different tools and nobody sees the full picture.

  • Phone calls go to CallRail or OpenPhone or the carrier-provided app. Sometimes they make it into the CRM. Sometimes they don't.
  • Web forms go to the owner's Gmail inbox, maybe also to a CSR, maybe also to Jobber as a Request.
  • Google Local Services leads sit in the LSA dashboard with no timestamp visible next to the CRM record.
  • Facebook and Instagram form fills go to a different place entirely, or to an integration that silently broke three weeks ago.

The CSR opens each tool separately. By the time they've checked all four, 30 minutes has already passed. 100 times means you are already out of the deal.

The number you should actually be tracking

Time from new lead created to first human contact made. In minutes. Measured by CSR, by lead source, by time of day. If that one number is visible to you weekly, every other marketing decision you make gets better, because you finally know whether the traffic you're buying actually turns into conversations.

Ask these of your own data

Get response time in front of you weekly, by CSR and by source.

Every one of these sits across your form provider, your phone system and your CRM. Answering any of them today means opening three tools and a spreadsheet.

  • What's the median time from new lead to first contact in the last 30 days?
  • Which lead source has the worst response time?
  • How many leads last week got no response at all?
  • Which CSR has the fastest average response time, and what's their close rate?
  • Of the web forms submitted after 6pm yesterday, when was each one first contacted?
  • Are we faster on Google Local Services leads or on our website forms?
