Following up without nagging

A customer you liked, a job that went well, and then two years of nothing — until you drive past the house and see another contractor's truck in the driveway. Odds are you were not fired. They needed something, could not find your number, and searched instead.

The beat before the job — answering the lead fast and following up on the estimate — is where the response-time research lands. Harvard Business Review (March 2011) found most firms take 42 hours to reply to a web lead, and 23% never reply. Post-job follow-up is a different problem: staying useful without filling the customer's phone.

The fix is not more messages. It is a message that shows up when the customer would have been thinking about the work anyway. That timing comes out of what you installed and how long it lasts.

Three tests before you hit send

A check-in reads as helpful or as pestering for reasons that have little to do with tone. Run it against three questions.

Does it carry information they don't have? "Just checking in" carries none. "Your unit's first cooling season starts in about a month, and the manufacturer wants the filter changed before it runs hard" carries some. If you cannot name the thing, you do not have a reason yet.

Is the timing on their clock or yours? A slow week is not an event in the customer's life. The end of a warranty, the first freeze, the spring thaw, the second season on a new deck — those are.

Can they ignore it at no cost? A helpful check-in is complete whether or not they reply. A nagging one demands an answer, then implies something when it does not come. Write every touch so silence is an acceptable outcome.

One more rule: for every message that asks for work, send at least one that asks for nothing. Customers count these even when you don't.

Set the clock on the work, not your calendar

Most trades already have a follow-up schedule built into what they installed. Intervals differ by manufacturer and by product, so go by the paperwork you handed over — repeat-customers has the trade-by-trade table for timing the next visit itself. A few reasons to reach out sit outside that interval entirely:

That reason is what brings the customer back. It is also the one most trades never send.

The first 30 days are quality control

Early follow-up is not retention. It is catching your own mistakes while they are still cheap.

Call or text within 72 hours of finishing anything the customer lives with — a floor, a paint job, a fixture, a system that runs. Small complaints surface in the first week and grow the longer they sit. A caulk line the customer mentions on day three is a five-minute stop. The same caulk line at month six is the story they tell about you.

Then a real 30-day check on larger work, once they have used it through a normal cycle. Name the thing: how's the second bathroom draining? is a question. Everything good? is a formality, and gets a formality back. Some work sets its own early date instead — a roof after the first heavy storm, a deck through its first spring, a generator after the first exercise cycle.

If a workmanship warranty runs a year, put a reminder at eleven months. Calling before it expires costs you one repair and buys a customer who tells people you came back. Learning about the problem in month fourteen costs you the argument instead.

How often is too often

For most residential trades, two to four planned touches a year is the ceiling — the seasonal ones plus anything the work itself triggers. Property managers and commercial accounts absorb more, because answering vendors is part of their job, not an interruption to their evening.

Three signals say pull back. Two check-ins in a row with no reply: drop to once a year, on the strongest date you have. An explicit "we're all set, we'll call you": seasonal reminders only, no offers. A STOP text or an unsubscribe: stop immediately, and write it down where you will see it before the next round.

Texts and email have rules attached

A message you type yourself to a customer who gave you their number sits in different territory than a list you upload to a texting platform. Where the line falls is fact-specific, and it has moved in court. In February 2026 the Fifth Circuit threw out the written-consent requirement for automated telemarketing calls in Texas, Louisiana and Mississippi. The FCC's rule still stands everywhere else. Two things are stable enough to plan around.

A service message is not telemarketing. A message carrying no offer is treated as service, and a customer who handed you their number for the job has generally consented to that. A message that sells needs real consent, and an existing customer relationship is not consent.

The Do Not Call Registry has a carve-out. The FTC's Telemarketing Sales Rule lets you call a listed number for 18 months after the customer's last purchase or payment, and three months after an inquiry — unless that customer has asked you specifically to stop. Several states, Florida, Oklahoma and Washington among them, stack stricter statutes on top, with private rights of action and damages counted per message.

Honor a STOP the moment it arrives. FCC rules give you ten business days at the outside.

Commercial email has its own requirements under the federal CAN-SPAM Act: a working opt-out that stays live for at least 30 days after you send, opt-outs honored within 10 business days, and a valid physical postal address in the message. A message made up only of warranty, recall or safety information about something the customer bought from you counts as transactional, and those requirements do not attach. Fold an offer into it and it is commercial again.

CAN-SPAM is enforced by the FTC and state attorneys general rather than by the recipient, though some state email laws do let the recipient sue. The FTC's CAN-SPAM Act: A Compliance Guide for Business is plain-language and worth reading once. Before you send to a list rather than to a person, run it past an attorney in your state — an hour of their time costs less than per-message penalties.

The reason to call is in the job record

Good follow-up runs on details: the model you installed, the date, the line item they cut for budget, the thing you told them to watch. In DoneQuote you open the customer and see the quotes and jobs you have already done for them, so the reminder you send can name the actual work instead of asking a generic question.

Set the date the day you finish, not the day you remember. A customer who hears from you when the work needs attention does not experience it as a follow-up. They experience it as somebody who kept track.
