Plumber estimate follow-up automation is a set of triggered texts and emails that go out automatically after you send a quote, so a customer who’s on the fence gets a nudge on day 1, day 3, and day 7 without anyone on your team having to remember to do it. It runs through your existing field service software, a dedicated follow-up tool, or a custom workflow built for your business. Most setups cost somewhere between a few hundred dollars a month and a couple thousand, depending on how much of it is off-the-shelf versus built to fit your process.

That’s the short version. Here’s the longer one, because “set up some follow-up texts” undersells what’s actually going on and why it matters right now.

Why does estimate follow-up matter so much for plumbers?

Because most plumbing companies are too short-staffed to follow up consistently, and the labor math backs that up. The Bureau of Labor Statistics projects 7% growth in plumbing, pipefitting, and steamfitting jobs from 2025 to 2035 (U.S. Bureau of Labor Statistics), and there are roughly 42,000 openings a year in the trade (U.S. Bureau of Labor Statistics). That’s not a hiring crisis you solve by Friday. It means the techs you have are already stretched, your office manager is already juggling scheduling and billing, and the person who’s supposed to call back that $6,000 water heater estimate on day three is the same person answering the phone, dispatching trucks, and closing out invoices.

Nobody forgets to follow up on purpose. It just falls off the list because the list is too long. An estimate that sits untouched for a week isn’t a “no.” It’s a lead that went to whoever called back first.

What does a good follow-up automation actually do?

At the core, it’s a sequence tied to one trigger: the estimate gets sent. From there:

  • A text goes out same day or next morning: “Hey, this is [Name] from [Company]. Just following up on the estimate we sent for your water heater. Any questions?”
  • A second touch at day 3 if there’s been no response, maybe with a financing option or a reminder of availability.
  • A third touch at day 7, often with a soft deadline or a seasonal note (“we’re booking up for next week, want to lock in a slot?”).
  • If the customer replies, texts, or clicks anything, the sequence stops and routes to a human. Automation should never argue with a customer or negotiate price. It just keeps the conversation alive until a person can take over.

The good versions also log everything back into your CRM or field service platform, so your office isn’t guessing which estimates are still open. The mediocre versions are just a text blast with no branching logic, which annoys people and gets you marked as spam.

How much does it cost to set up?

It depends on where you start.

If you’re on ServiceTitan, Housecall Pro, or a similar platform, some of this may already be a feature you’re not using. That’s the cheapest path: turn on what you’re paying for, write better copy, test it for a month.

If you want a dedicated tool bolted onto your existing phone and CRM setup, expect a monthly SaaS fee plus messaging costs, typically in the low hundreds per month depending on volume.

If you want something built specifically around how your business quotes and closes jobs (different sequences for emergency repairs versus remodel bids, different timing for high-ticket water heater replacements versus a $200 faucet repair), that’s a custom build. At Solas AI, this kind of workflow usually starts as a paid exploration milestone ($800) to map out your actual estimate-to-close process, then moves into a build on a monthly retainer, starting around $497/month for something focused and scaling up to $2,497/month for a fuller system that touches scheduling, review requests, and reactivation campaigns too. There’s also a one-time setup fee of $1,497 if you want it stood up fast rather than phased in.

The system runs on infrastructure your business owns, not a black box you’re renting forever. If the engagement ends, the automation keeps running. That matters more than it sounds like it should, because a lot of “AI tools” for contractors are really just subscriptions you lose access to the day you stop paying.

Should the estimate itself change too?

Yes, and this is where a lot of plumbers leave money on the table before follow-up even becomes relevant. Homeowners are shopping speed as much as price. In a recent survey, 93% of homeowners said receiving fast, upfront estimates affects who they hire (Housecall Pro 2025 Homeowner Survey). If your estimate takes three days to go out because someone has to build it manually after the job walk, you’re losing some of these customers before your follow-up sequence ever gets a chance to run.

The fix is usually pairing instant or same-day estimate delivery (templated pricing, photo-based quoting, whatever fits your trade) with the follow-up automation on the back end. Speed gets you in the door. Follow-up keeps you from losing the ones who need a day or two to decide.

Is this worth it if you’re already busy running the business?

The data on this is a little uncomfortable. Most contractors already believe AI-driven tools help. 74% of residential contractors say AI is a key driver of business efficiency (ServiceTitan 2026 Residential State of the Trades Report). But belief and action aren’t the same thing. Only about 25% of contractors are actually using AI tools right now (ServiceTitan 2026 Residential State of the Trades Report). That’s a big gap between “I know this would help” and “I’ve actually done it.”

Worth noting: among the contractors who have adopted these tools, 48% report increased productivity and 45% report real time savings (ServiceTitan 2026 Residential State of the Trades Report). So the people who cross the gap tend to be glad they did. The gap itself, three out of four contractors thinking this matters but only one in four doing anything about it, is basically the whole opportunity. If your competitor down the street is in that 75% that hasn’t automated anything, every estimate you follow up on and they don’t is a job you get and they don’t.

What’s the honest downside?

Automation doesn’t fix a bad estimate, a bad sales conversation, or a plumber who oversells and underdelivers. It also won’t work if the messages sound robotic or if you set the cadence too aggressive and annoy people. And if your estimate process is genuinely chaotic (quotes living in someone’s head, no consistent pricing, no record of what was actually promised), you need to fix that first. Automation makes a decent process faster. It doesn’t make a broken one work.

I build these systems myself, on infrastructure the client owns, with security built in from the start because that’s my background before I did this full time. I’m not going to pretend every plumbing company needs a five-figure build. Some need a $497/month sequence and better estimate speed. Others need a fuller system tied into scheduling and reviews.
