Company Overview
Mainline Plumbing is a mid-size plumbing company based in the Greater Toronto Area operating a fleet of 15 service trucks. They handle residential and commercial plumbing emergencies around the clock — burst pipes, sewer backups, water heater failures, and more. As a growing operation, their after-hours call volume was becoming too much for the owner to manage personally.
The Problem
Before MSO, Mainline's after-hours calls went to the owner's cell phone. Every midnight pipe burst, every weekend sewer backup — the owner was the dispatcher, the screener, and the first point of contact. Every emergency meant waking up, calling a tech, hoping they'd answer, and chasing them until someone confirmed.
They explored traditional answering services, but those services only take messages. A shared agent would pick up, write down the details, and move on to the next caller. No dispatch. No follow-up. No escalation. The owner still had to wake up, read the message, call the tech manually, and manage the whole process. The answering service just added an expensive middleman.
The owner needed something structurally different — not someone to take a message, but a dedicated operations manager that could handle the entire after-hours operation: answer calls, determine urgency, dispatch the right tech, follow up until confirmed, and escalate through the team if needed. Without waking the owner for a dripping faucet.


Mainline's real /tracking view — every dispatch timestamped from call to confirmed tech.
The Solution
Mainline Plumbing implemented MSO's Full Dispatch plan ($749/mo flat). Setup took 30 minutes during a single kickoff call.
MSO now acts as Mainline's dedicated after-hours operations manager. It answers every call in under 3 seconds, classifies whether it's a real emergency or a routine request, and dispatches the on-call technician via SMS with full job details. Then it follows up — if the tech doesn't respond within 3 minutes, MSO automatically escalates to the next person on the roster, then the next. It doesn't stop until someone confirms.
Every call, dispatch, and outcome is logged to a real-time dashboard the owner can check anytime. Non-emergency calls (dripping faucets, quote requests) are screened and scheduled for morning follow-up. Techs only get woken for real emergencies.
Before MSO: The owner's answering service took a message. Then the owner had to wake up, call the tech, chase them down, and manage the whole thing manually.
After MSO: Everything is handled start to finish. Dispatch, follow-up, escalation, logging — the owner wakes up to resolved jobs, not voicemails.
500+ emergency dispatches. Zero missed calls. Zero churn. MSO has been Mainline's after-hours operations manager since day one.
