Stop losing St. Louis burst-pipe calls to voicemail at 2 AM.
In St. Louis, a frozen pipe lets go on the coldest night of the year and the homeowner needs a plumber now — whoever answers gets the job. Callbook is the AI receptionist for St. Louis plumbing companies: it answers every call 24/7, books the appointment, and texts you the details. Flat $79/mo, no contract, keep your number.
Why St. Louis plumbers can't afford a missed call
St. Louis has some of the oldest housing stock in the Midwest — block after block of century-old brick homes in neighborhoods like Tower Grove, Soulard, and South City, many still on aging galvanized supply lines and clay sewer laterals. That age drives steady, often urgent demand: tree roots invade old laterals and back sewage into basements, and hard Missouri water scales up pipes and water heaters. Winters swing hard — a deep freeze cracks supply lines and sends burst-pipe emergencies in clusters, almost always after hours. The metro spreads across the city and out into St. Charles, Chesterfield, and the Metro East, so crews cover long distances between jobs. When a homeowner stands in a flooding basement at midnight, they call down the list until a plumber picks up. The one who answers books the work; every call to voicemail goes to the next name.
If Callbook books just one extra job a month, it has already paid for itself several times over.
Most shops miss far more than one call a month.

What your AI receptionist handles
Flags burst pipes and sewer backups
Recognizes 'my basement is filling with water' or 'sewage is coming up the drain' as urgent, flags it for immediate dispatch, and can route to your cell — so a flooding emergency jumps ahead of routine work.
Answers every plumbing call 24/7
Your crew is finishing a water-heater swap in Chesterfield when a homeowner in Soulard calls about a burst pipe at midnight. Callbook picks up on the first ring, captures the problem and address, and texts you right away — no voicemail, no lost lead.
Books the appointment before the call ends
Collects the customer's name, service address, problem, and preferred window, then drops the job into your calendar — so your dispatcher knows exactly where the next truck is headed.
Texts you every lead instantly
You get the caller's name, address, problem, and urgency the moment the call ends — so you can triage from the truck and send the right tech to the right job.
Asks the right plumbing questions
Captures whether the water is shut off, where the leak is, and how fast it's spreading — so your tech rolls up knowing what they're walking into instead of guessing from a voicemail.
Covers nights, weekends, and deep freezes
Burst pipes and sewer backups don't keep business hours. Callbook works 24/7/365 — when the next hard freeze hits and your competitors are asleep, you're still booking jobs.

Why St. Louis shops pick Callbook
Aging brick homes drive urgent repairs
Century-old housing across South City and beyond runs on galvanized pipe and clay sewer lines that fail with little warning. Those repairs can't wait, and the homeowner books whoever answers first. Callbook makes sure that's you.
Hard freezes burst pipes in clusters
A St. Louis cold snap cracks supply lines all over the metro on the same night — and the calls come at 2 AM, not 2 PM. Callbook answers every one, triages the emergencies, and books them while your competitors' phones ring out.
Old sewer laterals mean messy emergencies
Tree roots in aging clay laterals back sewage into basements after heavy rain. Callbook recognizes a sewer backup as urgent, captures the address, and texts you immediately so you dispatch fast.
A spread-out metro keeps crews driving
Covering the city plus St. Charles, Chesterfield, and the Metro East means technicians spend hours between jobs. Callbook keeps answering and booking while your crew is on I-44 or I-70, so no lead dies to voicemail.
Simple, flat pricing
Questions plumbers ask
Will my St. Louis customers know it's an AI?
Most can't tell. It talks naturally, understands plumbing emergencies, and books the job in about a minute. A homeowner standing in a flooding basement is far happier getting booked immediately than hitting voicemail and calling the next plumber.
Do I have to change my phone number?
No. You keep your existing number. We forward after-hours and missed calls to Callbook — or all calls if you prefer. Your customers notice nothing.
Can it handle a middle-of-the-night burst pipe?
Yes — that's exactly what it's for. Callbook answers 24/7, flags the emergency, captures the address, and texts you immediately so you can dispatch while the competition's phone rings out.
Does it ask the right questions for a plumbing call?
It captures whether the water is shut off, where the leak is, and how urgent it is, then texts your team — so your tech arrives knowing the situation instead of guessing.
What if a customer wants to speak to a person?
It can transfer the call straight to you or take a message for a callback. No lead is lost.
Is there a contract or setup fee?
No contract. Flat $79/month, no per-minute charges. Setup takes about a day — configured for your services, hours, and St. Louis-area service map — and you can cancel anytime.
