Plumbing is the least seasonal of the home services trades, and a large share of its calls arrive after hours: a burst pipe, a backed-up sewer, a water heater failing on a Sunday. A homeowner with water on the floor calls down the list until someone answers. Every missed call is a $200 to $600 service call, and sometimes a $1,500 to $6,000 repair, going to the next shop.
This guide is for plumbing shops with one to ten trucks that already have lead flow and are losing part of it at the phone. The fix has layers: measure the missed calls, decide who answers during the day, add an AI or human service for nights and overflow, and connect it to your dispatch software. Costs run from about $49 a month for a basic AI line to several hundred a month for flat-rate 24/7 booking.
Measure how many calls you miss before buying anything
Pull your phone carrier’s log or your call tracking report for the last 30 days and count calls that rang out, hit voicemail, or came in outside office hours. Listen to a sample of voicemails to see how many were real jobs. Owners tend to underestimate the number because the misses happen while they are under a sink. If you have no call tracking, CallRail records calls and tags them by source on a monthly subscription, and it connects to ServiceTitan. The drawback is that measuring costs a month you would rather spend fixing the problem, but it gives you the number you need to judge whether a $49 or a $449 a month service pays for itself.
Decide who answers during business hours
Daytime calls should go to a person who can book, quote a dispatch fee and calm a frustrated homeowner. In a one or two truck shop that is often the owner, which means calls get missed on every job. The options are a part-time CSR, a shared office manager, or routing the line to a service during the hours you cannot cover. Set a target: answer within three rings and book or schedule a callback inside the call. Whatever you choose, record the booking rate (calls booked divided by calls answered) every week. The trade-off of hiring is fixed cost in a trade where revenue per call is modest. The trade-off of doing it yourself is the misses you counted in the step above.
Add an AI answering line for nights and overflow
AI phone agents built for home services now answer, qualify and book into your schedule. Rosie starts at $49 a month for 250 minutes and connects to ServiceTitan and Housecall Pro on its $299 Growth tier. Sameday charges a flat $449 to $789 a month per its own comparison page and books 24/7. Avoca and Netic sell to larger shops on enterprise quotes and integrate with ServiceTitan. The upside is that the line is answered every time and the cost is fixed. The drawback is that an AI agent handles the common call well and the odd one badly; a homeowner describing sewage in a basement may need reassurance a script cannot give. Test with your own calls, listen to recordings weekly, and keep an escalation path to a human on call.
Use a human or hybrid service where the caller is upset
If your call mix is heavy on emergencies, a human answering service or a hybrid of AI and people may close more of those calls. Smith.ai offers an AI receptionist from $97.50 a month with a human hybrid tier and connects to ServiceTitan, Housecall Pro and Jobber (Jobber via Zapier). Answering Service Care is a multi-industry answering service with a home services program, priced on quote. Give the service a script with your dispatch fee, your service area and the questions your own dispatcher would ask. The drawback is cost per call: human minutes cost more than AI minutes, so this works for overflow and emergencies and gets expensive as the only line.
Connect answering to your dispatch software and audit the bookings
A booking that lands in an inbox is still a missed call if nobody reads it until morning. Pick a service that writes directly into your operations software (ServiceTitan, Housecall Pro and Jobber are the common integrations on this page) so the night job appears on the board for the first tech out. Then audit: once a week, compare what the service logged against what was dispatched and invoiced. Cancel what does not convert. The drawback is setup time, usually a few hours of mapping job types and service areas, and a monthly tier high enough to include the integration.
