DPW's own count puts Baltimore at roughly 1,000 water main breaks a year on a system where more than 70 percent of housing predates 1940 and shares a structural wall with the house next door. AutoRev is an AI receptionist for plumbers in Baltimore, Maryland, trained to ask whether a neighboring rowhouse unit has also had trouble, and to sort a real leak from the kind of six-figure billing error that has shown up in local news for a decade. It answers every call, text and web chat day or night, books the job, quotes from the pricebook, chases the estimate, and invoices when the work is done. It reaches the 410, 443 and 667 area codes: start in Fells Point or Hampden and it covers you clean out to Towson, Catonsville, Dundalk and Glen Burnie.

Pick a time below. We go through your Baltimore call volume, what you are missing after hours, and what it would answer first.
Baltimore rowhouses share an actual structural wall with the house next door, and construction like it dates to the 1820s. A stack or shared drain failure in one unit is frequently a second household's emergency within hours, and a caller who mentions the neighbor has also had trouble is describing the same underlying job.
Baltimore's water billing system has a documented history of large, erroneous charges going back at least to 2015, and disputed bills are still surfacing in local news this year. A caller staring at a huge number is often trying to work out whether it is a real leak or a city billing mistake before deciding whether to book anyone at all.
DPW's own figure is roughly 1,000 water main breaks annually across 1,500 miles of aging mains, and the rate spikes hard in cold snaps rather than climbing gradually through winter. A single January morning can produce dozens of breaks across the city at once.
The most recent DPW count leaves 58,508 service lines, 13 percent of the system, listed as unknown material. Homeowners are getting letters about it now, and a fair number are calling a plumber before or instead of completing the city's own survey.
Baltimore has spent roughly $780 million on the Back River Headworks project and related work under a federal consent decree, and reported about 94 percent of overflow volume eliminated as of a January 2024 meeting, short of the target. The city is now asking for a 16-year extension, and basement backups after heavy rain are still a live complaint, not a solved problem.
What the caller says, and what happens next.
"Both my drains are backing up and my next-door neighbor just texted me saying the same thing is happening at her place."
Two adjoining units reporting the same symptom on the same morning is a strong signal that the failure is in a shared stack or lateral, not two coincidental clogs. AutoRev asks whether the neighbor has called anyone yet, whether both households share a party wall, and books a camera inspection that accounts for both addresses instead of a routine snake for one.
"My water bill this month is $600 higher than usual and I don't know if I have a leak or if the city messed up again."
Baltimore's billing history means this exact question comes up often, and it is not automatically a service call. AutoRev asks about any recent change in usage, runs through the basic signs of a hidden leak, and either books an inspection or points the caller toward DPW's billing dispute process, whichever the answer calls for, instead of assuming every high bill means a truck roll.
"There's no water pressure at all and I can hear something running in the wall."
On a morning like this, the same call is landing across dozens of blocks at once, consistent with DPW's own record of double-digit simultaneous main breaks during cold snaps. AutoRev separates callers hearing active running water from callers with a simply frozen line, pushes the active leaks to the tech on rotation first, and books the rest into the day instead of leaving them on hold behind a single overwhelmed line.
Trained on Baltimore's party-wall construction, it asks whether an adjoining unit has also had trouble before booking, so a shared stack failure gets diagnosed as one job instead of two separate dispatches that both miss the real cause.
Baltimore's water bills have a documented history of significant mistakes. AutoRev asks the right questions to distinguish a real leak from a city billing problem, so a shop is not sending a truck to a house that never had a plumbing issue at all.
DPW's own record shows double-digit simultaneous main breaks during hard freezes. AutoRev answers unlimited calls at once, separates active leaks from frozen-but-intact lines, and gets the real emergencies to a tech first.
With 13 percent of the city's service lines still listed as unknown material and notification letters going out now, homeowners are calling with real but non-billable questions. AutoRev answers accurately, distinguishes the street-side line from the homeowner's own plumbing, and books an inspection where one makes sense.
Most AI receptionists on the market are the same handful of white-label voice platforms with a different logo on the login page, and all of them stop at taking a message. AutoRev is proprietary end to end, built on the best models available and tuned to the individual shop. It works on top of the software you already run, or it runs the whole operation itself. Either way, picking up is where it starts rather than where it finishes.
Every call, text and web chat in under 30 seconds, day or night, unlimited at once. Emergencies get triaged against your on-call rules and pushed straight to the tech on rotation.
The caller who hung up undecided gets a text with what you quoted and a link to pick a time. Most of them were not saying no, they were saying not right now.
It keeps working the lead until they book or tell you no. No lead sits in a folder waiting for someone in the office to remember it.
Appointment confirmations and reminders go out on their own, which is the cheapest way to cut no-shows you will ever find.
The customer gets told when someone is heading over and who it is. Fewer 'where are they' calls tying up your line.
Real ranges from your pricebook on the call, then a written estimate sent while the job is still fresh.
Unsold estimates get worked on a schedule until there is an answer. This is usually the largest pile of recoverable revenue a shop is sitting on.
The invoice goes out off the completed job, payment reminders go out after it, and the customer pays on a link.
A Google review request after every completed job. Local rank moves on review velocity and this is the step every busy shop drops.
Nobody hands you a login and wishes you luck. We sit with every shop we take on and build the agent around your market and your operation before it takes a single call.
Your ZIP codes, your service area boundary, local regulations and the standard operating procedures that apply where you work. It knows which addresses you cover and which you do not.
We sit down and build the call script around how you actually run jobs. If you would rather hand it over, we write it for you and you approve it.
Want it wired into ServiceTitan, Housecall Pro, Jobber or FieldEdge? We do the integration work. Want AutoRev to be the system instead? That works too.
We help you set up call forwarding, so the number on your trucks and your Google listing stays exactly as it is. Nothing on your marketing has to change.

Water detail published by Baltimore City Department of Public Works.
Baltimore's Department of Public Works keeps roughly 1,500 miles of water main running under the city, and most of it went into the ground before 1930. A main has a working life of about 75 to 100 years. DPW's own stated pace of replacement is 15 miles a year, which is not close to enough to keep ahead of a system that old, and the department's own figure for the result is about 1,000 water main breaks a year. In a single cold snap in January 2025, 53 breaks and outages were logged across the city and county in the same stretch of days. A year later, DPW was working 18 active breaks and 22 leaks at once during another freeze.
That is the infrastructure story. There is a second, separate story running underneath it that has nothing to do with pipes failing and everything to do with the bill for the water that comes out of them. A 2015 city report found more than 38,000 customers had been overcharged over three years. City Council held hearings on missing and inaccurate bills again in 2021. As recently as this year, local news has covered a woman fighting a $228,000 water bill tied to an entire neighborhood association, a downtown nightclub owner staring at a $46,176 charge for one month, and a family disputing $3,600 on a vacant house. None of that is plumbing. All of it means a fair number of calls into a Baltimore plumbing company start with someone trying to figure out whether an alarming number on a bill reflects a real leak on their side of the meter or a city billing error on the other side of it, and the difference matters before a truck ever gets scheduled.
Then there is what the houses themselves are made of. More than 70 percent of Baltimore's occupied housing was built before 1940, and rowhouse construction here goes back to the 1820s. These are true party-wall buildings, sharing an actual structural wall rather than sitting on adjacent lots, so a stack failure or a shared drain line problem in one unit routinely turns into a second household's problem next door within the same day.
DPW's most recent lead service line count, from September 2025, puts 9,193 lines at known or presumed lead, 2 percent of the system. The bigger number is the 58,508 lines, 13 percent of the total, still listed as unknown material, and notification letters are going out now to properties with a known or predicted lead line.
Layer a still-active federal sewer consent decree on top of it. Baltimore has spent roughly $780 million bringing overflow volume down, but the city itself put the number at about 94 percent eliminated as of a January 2024 meeting, short of target, and it is now asking for a 16-year extension pushing full compliance from 2030 to 2046. Basement backups after heavy rain are still a live complaint here, not a solved problem.
No dedicated plumbing answering service was found running a Baltimore page as of this writing. A shop willing to answer a rowhouse stack question, a billing confusion call, and a lead-line question correctly, on the first ring, is answering a market nobody else has bothered to build for yet.
The right one asks whether the rowhouse next door has the same problem before it books a truck for either address, and it can tell a real leak from a six-figure billing error on the same call. AutoRev is trained on exactly that split. It runs proprietary end to end, works with your existing software or replaces it outright, and stays live on every call, day or night. Hear it handle a real Baltimore scenario on the demo line before deciding anything.
Yes. More than 70 percent of Baltimore's housing predates 1940, and true party-wall construction has been the dominant form here since the 1820s. AutoRev asks whether a neighboring unit is showing the same symptoms before booking, which matters because a shared stack or lateral failure often shows up as two separate calls from two separate addresses.
It asks the right questions to sort that out. Baltimore's water billing system has a well-documented history of large errors, including a 2015 finding that more than 38,000 customers were overcharged. AutoRev walks a caller through recent usage and basic leak signs before deciding whether to book an inspection, instead of assuming every alarming bill is a plumbing emergency.
That is the exact case Baltimore produces every winter. DPW's own figures show roughly 1,000 main breaks a year, with double-digit simultaneous breaks during hard freezes. AutoRev answers unlimited calls at the same time, separates active leaks from frozen lines by asking about running water and pressure, and routes real emergencies to the tech on rotation first.
Yes. DPW's most recent count still lists 58,508 service lines, 13 percent of the system, as unknown material, and notification letters are going out to residents now. AutoRev explains the difference between the street-side line and the homeowner's own interior plumbing, and books an inspection when the situation calls for one rather than turning it into a wasted truck roll.
You draw the boundary. Most Baltimore shops set roughly a 30 mile radius across the 410, 443 and 667 area codes, reaching Fells Point, Federal Hill and Canton out through Towson, Catonsville, Dundalk, Columbia, Ellicott City, Glen Burnie and Owings Mills. Every caller's address gets matched against that boundary automatically, so a job outside it gets handled honestly instead of becoming a wasted trip.
Plenty of Baltimore shops already run ServiceTitan or Housecall Pro, and switching software isn't a requirement here. It reads and writes ServiceTitan, Housecall Pro, Jobber, FieldEdge and hundreds of other systems. It also runs as the system itself, covering dispatch, scheduling, pricebook, estimates, invoicing and payments. Work on top of what you have, or move onto it.
A Baltimore call that starts as a billing question can still end with a booked job. Once it does, answering is the first step, not the product: it texts back the caller who hung up undecided, follows up until they book or say no, sends the appointment reminder, tells the customer when a tech is on the way, sends the estimate, chases it until there is an answer, invoices off the finished job, sends payment reminders, and asks for the Google review once everything is settled.
Hear it answer a call, or book 20 minutes and we will walk through what you are missing after hours.
