If your team sends 20 estimates a month and only follows up on the ones customers happen to call back about, you’re leaving real jobs on the table. Plumbing leads convert at 15.61% when someone actually engages them (CallRail), which is one of the best conversion rates in home services. But that number assumes follow-up happens. Most shops let it slide after one text.

I’ve spent the last few years building automation systems for service businesses, plumbing included, and estimate follow-up is one of the easiest things to fix with a system that runs itself. Not because the idea is complicated. It isn’t. It’s because nobody on your team has time to chase 40 open estimates while also running calls, ordering parts, and managing the crew.

Why do estimates die without follow-up?

Estimates die because the person who sent it moves on to the next job and never circles back. A homeowner gets a $4,800 quote for a water heater replacement, says “let me think about it,” and that’s the last anyone hears from your office unless they call in. Meanwhile 66% of home service businesses say lead follow-up and conversion is a top operational challenge (CallRail). That’s not a small-shop problem. That’s an industry-wide gap, and it’s the same gap that eats revenue on the phone lines too: 14% of inbound calls to home service businesses go unanswered, and 85% of those callers never call back (CallRail via Businesswire). Same behavior pattern with estimates. Give someone one shot at a follow-up and if it doesn’t land, they quietly go hire whoever calls them back first.

What does automated estimate follow-up actually look like?

It’s a sequence, not a person. When your tech or office manager sends an estimate, the system starts a clock. If the customer doesn’t respond, a text goes out at day 2 asking if they have questions. Day 5, another text with a specific nudge, maybe mentioning financing options or scheduling availability. Day 10, an email recap of the scope and price. Day 15, a final check-in before the estimate gets marked cold. Every step is logged so if the customer replies “yes let’s do it” at any point, the sequence stops and the job gets booked.

None of this requires a person to sit and remember which estimate is on day 5 versus day 12. That’s exactly the kind of repetitive tracking work that a system handles better than a human, because humans get busy and let it slip. I build these on infrastructure the client owns outright (n8n workflows, a database that’s theirs, not mine), so if we ever part ways, the follow-up sequences keep running. No vendor lock-in, no rebuilding from scratch with a new provider.

What does it cost to not do this?

Let’s do simple math. Say your average job from an estimate is $3,500 and you send 25 estimates a month. At a 15.61% close rate with good follow-up (CallRail), that’s roughly 4 jobs a month, about $14,000 in revenue. If half your estimates get zero real follow-up because nobody has time, you’re probably closing at half that rate or worse. That’s $7,000 a month left on the table, every month, indefinitely.

Now compare that to labor cost. The median annual wage for a plumber is $62,970 (U.S. Bureau of Labor Statistics), which works out to roughly $30 an hour. If your office manager or a tech spends even 5 hours a week manually tracking and texting estimate follow-ups, that’s $150 a week, about $650 a month, just in time spent on a task that a workflow can run continuously without getting distracted by the phone ringing. The automation doesn’t replace the person. It removes the busywork so they can spend that time on calls, scheduling, or actually closing the warm leads the sequence surfaces.

Why does this matter more now than five years ago?

Because the labor market for plumbers is only getting tighter. The BLS projects about 44,000 plumber job openings a year through 2034 (U.S. Bureau of Labor Statistics), which tells you two things: demand for the trade isn’t slowing down, and competition for good techs and for customers is only going to increase. Every estimate you don’t follow up on is an estimate your competitor’s automated system (or their more organized office manager) is happy to pick up instead. You can’t out-hustle a labor shortage by hoping your team remembers to text back a $6,000 sewer line quote from two weeks ago.

What should a plumbing shop automate first?

Start with the estimate follow-up sequence before anything fancier. It’s the highest-leverage, lowest-risk automation you can build because it touches revenue directly and doesn’t require changing how your techs work in the field. A basic version looks like this:

  • Estimate sent triggers a text within the hour confirming it landed and inviting questions
  • Day 2 and day 5 follow-ups if no response
  • A branch that flags “hot” responses (anything with a question or a maybe) for a human callback
  • A final day-15 message before the estimate rolls off active tracking
  • A simple dashboard so the owner can see open estimate value at a glance, not buried in a spreadsheet

Once that’s running clean, it makes sense to extend the same logic to missed calls and no-show reminders, since the same pattern (something falls through because nobody had time to chase it) shows up in all three places.

How much does this kind of system cost to build?

At Solas AI I run this as a monthly retainer rather than a giant upfront build, because most plumbing shops don’t want a six-figure software project, they want something working in a few weeks that pays for itself fast. Retainers start at $497/month for a Starter package, with a one-time setup fee of $1,497 to get the estimate follow-up workflows, texting, and dashboard built and connected to whatever CRM or field service software you already use. If you want to test the waters first, there’s a 30-day pilot at $497 to prove out the follow-up sequence on a subset of your estimates before rolling it shop-wide.

Everything runs on infrastructure you own. That’s not a sales line, it’s how I build things: self-hosted, no lock-in, the system doesn’t disappear if the vendor relationship ends. For a plumbing business, that matters because your estimate data, customer texts, and follow-up history are core business assets. They shouldn’t live in a system you can’t take with you.

If you’re sending estimates and hoping people call back, you’re relying on the exact behavior that costs home service businesses money every month. A short call is the easiest way to find out what an automated follow-up sequence would actually save you. You can book one at /book, no pressure, just a straight look at your numbers.
