A lead came in 40 minutes ago. You were on a roof, or under a sink, or driving between jobs, and you never saw it. By the time you call back, the homeowner has already talked to two other companies and booked one of them. The lead was real. The work was yours to lose. The only thing that beat you was the clock.
Speed to lead is the most underrated number in a service business. Not your reviews, not your price, not your ad spend. Just how many minutes pass between a lead reaching out and a real person talking to them. Here is what the research says the target is, why the window is so brutal, and how to actually hit it when you are the one doing the work.
How fast should you call a new lead back?
As fast as you physically can. The practical target most lead-response research lands on is five minutes. The hard number behind it comes from Harvard Business Review: in an audit of 2,241 U.S. companies, Dr. James Oldroyd and colleagues found that firms contacting a new lead within an hour were about 7 times more likely to qualify it than those who waited even an hour longer, and about 60 times more likely than those who waited 24 hours ("The Short Life of Online Sales Leads," HBR).
Read that again, because the gap is not small. Not 7 percent better. Seven times. A new lead is a perishable thing. The first few minutes are when it is worth the most, and the value drops off a cliff from there.
Firms that contact a new lead within an hour are about 7 times more likely to qualify it than those who wait an hour longer, and about 60 times more likely than those who wait a day. (Oldroyd, Harvard Business Review, audit of 2,241 U.S. companies.)
Why does responding fast matter so much?
Because the person on the other end is not waiting around for you. A homeowner with a problem is calling more than one company, working down the list on their screen. The first business that picks up and has a real conversation is usually the one that books the job. Not the cheapest. Not the best reviewed. The first one to answer.
It is the same reason voicemail does not save you. Per Invoca's home services data, fewer than 3% of callers who reach voicemail leave a message. The other 97% hang up and dial the next number. A missed call is not parked safely in an inbox waiting for your callback. It is already gone, usually to whoever answered.
What happens to a lead the longer you wait?
Every minute you wait, the odds tilt against you. Inside the first five minutes, you are talking to someone whose problem is top of mind and who has not committed to anyone yet. Wait an hour longer to respond and, per the HBR numbers, you are roughly 7 times less likely to qualify that lead than if you had reached them inside the first hour. Wait a full day and it is closer to 60 times less likely, and by then there is usually nothing left to qualify, because they hired the company that called back while you were still meaning to.
This is why "I'll get to it tonight" is so expensive. By tonight, the homeowner has usually already made the call and hired someone. The callback you make the next morning lands on a phone that belongs to someone else's customer now.
Why is fast callback so hard for contractors?
Because you are not sitting at a desk. You are the product. You are on the roof, in the crawlspace, in the attic, or shoulder deep under a sink, which is exactly where you cannot answer a phone. The calls come in during the hours you are least able to take them, and the harder you work, the more you miss. It is not a discipline problem. It is the structure of the job.
Forwarding to your cell does not fix this, it just moves the problem. Either you answer mid-job and rush the call, or you answer at dinner and resent it, or you do not answer at all and the caller gets what feels like a personal blow-off instead of a business voicemail. Hiring someone to sit by the phone works at a certain size and not before. The gap between "I should respond fast" and actually doing it is where the jobs quietly leak out.
How fast to call back in roofing, HVAC, and plumbing
The five-minute target is the same across the trades. What changes is when the calls hit and how fast the caller moves on.
Roofing
Roofing leads spike with weather. A storm rolls through and every homeowner with a missing shingle calls at once, usually while your crews are already slammed and the phone is ringing off the hook. Those leads are shopping three or four roofers in the same afternoon. Call back two days later and the tarp is already on, with someone else doing the job.
HVAC
HVAC runs on urgency and weather too. No heat in a cold snap, no cooling in a heat wave, and the customer is uncomfortable right now. They are not going to wait a day for a callback when the house is 88 degrees. Whoever gets a tech scheduled first usually wins, and that decision gets made on the phone in the first conversation.
Plumbing
Plumbing is the purest speed game of the three. A burst pipe or a backed-up main is an emergency, and the homeowner is calling down the search results until someone picks up. There is no comparison shopping when water is spreading across the floor. The first plumber who answers and says "we can be there" books it.
Restoration is the extreme version of all of it: the call is often a 2am crisis, the ticket is large, and the first company to answer almost always wins the work. The faster the response, the more of that you capture. The pattern never changes. The calls you most want are the ones you are least able to grab in the moment.
What actually makes fast callbacks happen?
Speed to lead is not a willpower problem, so willpower will not fix it. A system will. Here is the honest ranking of the usual options.
- Answer live, every time. The gold standard, and the one you cannot personally hit while working. This is exactly why owners burn out trying to be the receptionist and the crew at the same time.
- Missed-call text-back. Better than silence. It fires a text when you miss a call and recovers some of those leads. But a text is not a conversation. It does not qualify anyone or book anything, and a homeowner with an active problem usually wants to talk now.
- After-hours forwarding. Moves the call to your cell, which means it lands on you at the worst possible moment or not at all. Coverage on paper, not in practice.
- A receptionist. Real coverage during business hours, if the volume and budget support the hire. It still does not answer at 9pm on a Sunday, which is when a lot of these calls come in.
The cleanest way to win the speed-to-lead game is to take the callback out of the equation entirely. If the call gets answered the first time, there is no clock to beat. That is the job Willison does. Willison answers every call in seconds, 24/7, 365. It greets the caller, asks the questions you would ask, qualifies the job, books it straight to your calendar, and can text you the details so you hear about the lead before you are off the ladder. It picks up at 2am the same way it picks up at 2pm, and it never sends a real customer to voicemail.
What it does not do is the work. You still show up and close the job. Willison just makes sure the at-bat never gets skipped because you were busy earning the last one.

The lead you are most likely to lose is the one you never knew came in. Speed to lead is boring, unglamorous, and almost entirely about whether someone picks up. Fix the pickup, and you stop losing jobs you already paid to find.
Frequently asked questions
As fast as you physically can, and the target is within five minutes. Per Harvard Business Review research by Oldroyd and colleagues, firms that contact a new lead within an hour are about 7 times more likely to qualify it than those who wait even an hour longer, and about 60 times more likely than those who wait 24 hours.
Under five minutes is the goal. Under an hour is the line where the odds start falling off a cliff. Most new leads contact more than one company, so the first real conversation usually wins the job, not the lowest price or the best reviews.
No. Per Invoca's home services data, fewer than 3% of callers who reach voicemail leave a message. The rest hang up and call the next company, so voicemail is not a callback list you can count on.
It is better than silence, but a text is not a conversation. It does not qualify the lead or book the job, and a homeowner with an active problem usually wants to talk to someone now rather than trade messages.
You cannot answer a call from a roof or a crawlspace, so the fix is a system that responds for you. Willison answers every call in seconds, 24/7, qualifies the caller, and books the job straight to your calendar, so a missed call never becomes a slow callback.
