Sources: the booking rate is ServiceTitan's own, from its report on call booking rates across more than 3,000 trade businesses in the United States and Canada; the 2 figures beside it are from ServiceTitan's 2026 State of AI in the Trades, a survey of 1,032 contractors across HVAC, plumbing, electrical, roofing, garage door, pest control and commercial landscaping. The 3 figures that used to sit here are gone rather than dressed up: the 62 percent missed call figure was credited to a publisher that has never published it, the 78 percent figure is not in the study it named and that study's site is now a paid link farm, and the $4,200 job value had no source at all.

Why this hits St. Louis, MO shops in particular
The local shape of the problem here is basement waterproofing and sewer laterals. That matters because the shops losing this fight are almost never losing on the quality of the work. They are losing in the gap between somebody searching and somebody being spoken to.
The pattern repeats in three ways, and all three are worse for an owner-operated shop:
- The call arrives when nobody can take it. A homeowner with water on the floor or no heat rings in the evening, at the weekend, or in the middle of the job you are already on. That is precisely the window in which a small shop has nobody free to answer, and the homeowner is working down a list.
- The estimate goes out and then goes quiet. Most trade work is quoted and then decided days later. A quote nobody follows up sits against two other quotes that also went quiet, and the job goes to whichever shop happened to make contact again first.
- The finished job never becomes a review. Search ranking and the homeowner's shortlist both turn on reviews, and a review only exists if somebody asked for one while the customer was still pleased. Asking by hand after a long day is the task that never happens.
The honest arithmetic: an answering service or AI voice agent for a trade shop runs roughly $150 to $500 a month. At the job values in this trade, one recovered call pays for months of it. The decision is not close, which is why this page spends more time on the order to build things in than on whether to build them at all.
What this looks like in St. Louis, MO
In St. Louis, many homes feature basements because of the local climate and historical construction practices. These underground areas are prone to water intrusion from heavy precipitation and the high water table. Homeowners often call about dampness and leaks, particularly after seasonal thaws. Addressing these issues promptly demands immediate on-site inspection, but the wide range of foundation designs makes accurate diagnosis challenging. As a result, estimates are delayed, and project timelines extend, leading to increased overtime expenses and eroded customer confidence for the business.
Sewer laterals in St. Louis are frequently constructed from clay, a material that deteriorates with age and permits root intrusion. Numerous older districts still have original lines that fracture under soil stress. Upon receiving a backup report, technicians often need to dig for inspection. The common occurrence of such problems results in prolonged on-site assessments, and necessary components may not be stocked nearby. Consequently, resolution times lengthen, and the business's capacity for daily service calls diminishes.
Temperature variations in St. Louis lead to soil instability. The predominant clay soil swells with moisture and shrinks during dry periods, exerting pressure on subsurface pipes and building foundations. Homeowners report cracks or water seepage following each climate change. Determining if the issue is structural or waterproofing-related requires meticulous evaluation. Delays in providing clear explanations can increase customer anxiety, prompting them to look elsewhere and resulting in possible income reduction for the business.
Intense storms in the St. Louis region frequently result in abrupt flooding and sewer system overloads. The surge in emergency service requests following these incidents strains scheduling. Teams are forced to triage cases, with less critical ones postponed. This pressure on resources increases the likelihood of errors in evaluations or hasty repair work. Gradually, the business could develop an image of inconsistency, which hampers future expansion and financial success.
In St. Louis, the business tackles water intrusion by conducting camera inspections of basements to locate all entry points. This detailed evaluation allows for targeted waterproofing measures. Technicians apply sealants and fit drainage tailored to each home's foundation. The business also advises homeowners on maintaining exterior grading to prevent future issues, focusing on long-term solutions rather than quick fixes.
If calls are not returned, St. Louis residents often reach out to neighbours for drainage contractors they have used. They may also monitor weather alerts to prepare for incoming storms. Competitors who answer immediately often provide emergency tarping services to prevent further damage. In St. Louis, businesses that respond after heavy rains by offering rapid assessments earn a reputation for reliability in a flood-prone city.
- Older homes with basements demand urgent waterproofing. Moisture problems in St. Louis basements escalate quickly, and slow responses allow damage to spread, increasing repair costs.
- Clay sewer laterals prone to collapse. Sewer lateral failures in St. Louis require immediate attention, but hidden root systems complicate fixes, delaying resolution.
- Weather-induced soil movement strains foundations. Frequent freezes and thaws in St. Louis exacerbate foundation issues, making timely assessments critical to prevent further deterioration.
What this looks like on a real St. Louis, MO call
Before
A homeowner calls at a quarter to eight in the evening. Voicemail. They leave a message, or more often they do not. Your office manager finds it at eight the next morning, calls back, and gets somebody who booked another shop the night before. Nothing about your work was ever compared to anybody else's.
After
The same call reaches an AI voice agent. It asks whether there is water running, whether there is heat, whether the power is off, records the address and the fault, and texts the on-call technician a summary inside a minute. The technician calls back at eight fifteen. The job is on the board before the morning meeting.
The right build for each trade
Plumbing
- The after-hours emergency call is answered, triaged for urgency and dispatched to the on-call technician rather than left on voicemail
- Estimate follow-up runs by text on its own, because a homeowner deciding on a repipe or a water heater decides days after the visit
- Recurring work such as a water heater flush or a winterisation goes out as a scheduled campaign instead of being remembered by nobody
Heating and cooling
- During a heat wave or a cold snap the phone is answered by something that does not queue, so the overflow becomes booked jobs rather than lost ones
- Maintenance agreement renewals are chased automatically, which is the part of the book that quietly lapses when everyone is busy
- New system enquiries get a follow-up sequence that books the in-home consultation without a salesperson chasing it
Electrical
- Inbound work is qualified for job size, timeline and whether a permit is involved before it reaches your schedule
- Panel upgrade and car charger quotes get an automatic follow-up carrying the financing options, which is what most of the silence is actually about
- The review request goes out within hours of the job closing, while the customer is still standing in a house that works
Roofing
- Every storm damage enquiry is captured and triaged by area and urgency, including the ones that arrive all at once
- A multi-touch follow-up sequence runs across the whole decision window, because roofing is decided over weeks and not over a phone call
- The insurance conversation gets a prepared first reply, which is the point at which most homeowners stall

The first 30 days, in order
- Day 1. Put answering on your main line after hours. Nothing custom, nothing integrated, a forwarding number and a script. This alone recovers the calls you are losing tonight.
- Week 2. Connect the job management software you are already paying for to an estimate follow-up sequence. Every quote gets chased on its own, in your words, without anybody remembering to.
- Week 4. Turn on the review request on job close. It costs almost nothing, it runs forever, and it is the only item here that keeps paying after you stop looking at it.
Only after those three are running does a custom build make sense, and it makes sense for a specific reason: several locations or subcontractors to dispatch across, permit dependent scheduling, or a call flow your job management software cannot represent without somebody retyping everything. Until then a custom build is an expensive way to do what a forwarding number already does.
