How fast should you call back a lead? Speed to lead for contractors

Call within five minutes if you can, and always within the hour. The best-known study, an MIT / InsideSales analysis from 2007, found the odds of qualifying a web lead fell 21 times between a five-minute and a 30-minute callback; the research is old, but shared marketplace leads still go to whoever reaches the homeowner first. When you’re on a job, send a short text right away and promise a callback time.

What the lead response research actually says

Two studies get quoted on every sales blog, usually wrong. Both are old: one from 2007, one from 2011. Here is what each one measured, from pages we opened.

The MIT / InsideSales study (2007). MIT Sloan professor James Oldroyd and InsideSales.com CEO Dave Elkington looked at about three years of data on more than 15,000 web-form leads at six companies: how fast sales teams dialed and what happened next. Their headline: the odds of reaching a lead dropped 100 times when the first call came at 30 minutes instead of 5, and the odds of qualifying that lead dropped 21 times [1]. They also found 4 to 6 p.m. was the best window to reach people, and that after about 20 hours, extra dials actually hurt [1]. The study was presented at a 2007 marketing conference and co-written by a company that sold sales software, so read it as a strong hint, not a law.

The Harvard Business Review audit (2011). The same researchers, joined by Kristina McElheran, sent test web leads to 2,241 U.S. companies [2]. As the article’s own text is quoted by Venture Harbour, 37% answered within an hour, 23% never answered at all, and the average reply among those that did came after 42 hours [3]. Companies that reached out within the hour were nearly seven times as likely to qualify the lead as those that tried even an hour later, and more than 60 times as likely as those that waited 24 hours or more [3].

What home-service phone data adds. Invoca, a call-tracking company, reports that 27% of calls to home-service businesses go unanswered, and that fewer than 3% of callers sent to voicemail leave a message [4]. So a missed call is usually a silent lead. You only find it if you look at your call log.

Two honest caveats. These studies watched sales teams answering web inquiries, not homeowners with a leaking water heater, and they date from 2007 and 2011, before most people texted businesses. We haven’t found a newer public study that repeats them. But the direction has never been seriously disputed: the first business to talk to the customer has the edge, and the edge shrinks by the minute.

Web forms, phone calls and marketplace leads are not the same race

“Five minutes” means something different depending on how the lead arrived.

Rank them by urgency like this: live calls first, shared marketplace leads second, Google ad leads third, your own website forms fourth. Your own form leads still deserve five minutes; they’re just less likely to have three competitors dialing at the same moment.

How to build a 5-minute callback habit in a small shop

Nobody hits five minutes by trying harder. You hit it by making the lead impossible to miss and the reply take 20 seconds. Here’s a setup that works for a two-truck HVAC shop or a solo cleaner.

1. Send every lead to one phone. Website form emails, marketplace app alerts, Google ad notifications and the business line should all land on whoever is on lead duty today. If leads go to an inbox the office checks at lunch, they’re already hours old.
2. Give lead alerts their own sound. Save your form-notification and lead-app senders as contacts and give them a ringtone and text tone nobody else uses. Pick something you’ll hear over a compressor and won’t confuse with your group chat.
3. Name a lead owner for each day. In a shop of three, rotate it: Monday the owner, Tuesday the office manager, and so on. “Everybody watches the phone” means nobody does.
4. Save your callback and text templates as keyboard shortcuts. Type “;lead” and the whole first text appears. The templates are below.
5. Follow a fixed sequence. Call within five minutes. No answer: leave a short voicemail and send the text right away. Call again later that day, ideally late afternoon [1]. One more try the next morning, then a last text. Stop there; the MIT data suggests endless dialing past the first day backfires [1].
6. Write down the time. A shared spreadsheet with four columns is enough: when the lead came in, when you first reached out, the source, and whether it booked. Look at it every Friday.

If you want the phone itself to cover some of this, see setting up a missed-call text back and forwarding business calls to whoever is on duty.

Templates for the first callback and first text

Change the bracketed parts and save them on your phone. Keep the first contact short; the goal is a conversation, not a sales pitch.

First callback (they answer): “Hi [name], this is [your name] with [company]. You just asked about [furnace not heating / a bathroom remodel / weekly mowing] on our website. Is now a good time for two quick questions so I can get the right person out to you?”

Voicemail (keep it under 20 seconds): “Hi [name], [your name] from [company], calling about the [job] request you just sent. I’m texting you from this number too, so reply there whenever it’s easy. Talk soon.”

First text, right after the voicemail: “Hi [name], it’s [your name] at [company]. Got your request about [job]. I just tried calling. What’s a good time today for a 2-minute call? Or reply here with the address and a photo and I’ll start from that.”

Missed call from an unknown number: “Hi, this is [company]. Sorry we missed your call just now; we were on a job. How can we help? Reply here or call back at this number.”

Shared marketplace lead: “Hi [name], [your name] with [company] here. Saw your [job] request come through [platform]. We’re local in [town] and can usually look at it [this week / tomorrow]. Want me to hold a time for you?”

Last try, next morning: “Morning [name], just checking whether you still need help with [job]. If you’ve got it handled, no worries, and we’re here if anything changes.”

Texting a person who asked you to contact them is normal business, but don’t add them to promotional text blasts without permission. Once they reply, follow our guide to booking more jobs from calls to turn the conversation into an appointment.

What to do when you’re on a roof, under a sink or driving

Most owners of small shops are also the best tech, so five minutes sometimes isn’t possible. The fix is to make the first response tiny and the real conversation scheduled.

• Send a 10-second text from wherever you are. “On a job, will call you by 3:30. Is that OK?” A promised time beats silence, and it buys you an hour.
• Turn on an automatic reply for missed calls so every caller gets a text back even when you can’t touch the phone.
• Fix your voicemail greeting so it tells callers you’ll text them back and when. Wording ideas are in our voicemail greeting guide.
• Hand the phone off during long jobs. Forward the business line to a spouse, office helper or answering service for the afternoon you’re tearing off shingles.
• Batch callbacks at natural breaks. Lunch, the drive between jobs (hands-free only), and the 15 minutes after you pack up. Return the newest leads first; they’re the warmest.
• Plan for nights and weekends. Leads that come in at 9 p.m. still count. See handling after-hours calls.

Example of how it looks in practice (an illustration, not data): a roofer gets a web form at 10:40 while on a tear-off. At 10:42 an auto-text goes out. At 10:55, on a water break, he sends “I’ll call at 12:15.” At 12:15 he calls and books the inspection. The homeowner heard from him within two minutes and talked to him within two hours, which is faster than most of the companies in the HBR audit [3].

Measure your speed to lead every week

You can’t fix a number you never look at. (Speed is one piece of the system in our calls and leads guide.) Each Friday, sort your lead log and answer three questions: what was the median time to first contact, which source was slowest, and how did fast leads book compared to slow ones?

That table is a made-up example to show the format. In your own log, look for a pattern like the one above: leads reached in minutes book, leads reached hours later go quiet. Once you see it in your own numbers, the habit sticks. If a lot of leads are phone calls you never saw, call tracking will show you where they came from.
