Answering service

AI answering service for Bay Area contractors.

TenFour Pro answers the calls you miss while you are on a job. It tells every caller it is an AI assistant, takes the details your trade needs, books routine work into open times on your schedule, and texts you before anyone is promised urgent service.

It works wherever your phone rings. Below: how calls differ between trades and across the Bay Area, and what setup involves.

  1. 1

    A call you miss is forwarded.

    Your carrier forwards the calls you cannot pick up, or callers dial the assistant’s number directly.

  2. 2

    The assistant answers.

    It discloses AI and recording, then takes the caller’s name, callback number, address, and problem.

  3. 3

    Routine work gets a time.

    It offers open times inside your hours and books the one the caller picks.

  4. 4

    Urgent work waits for you.

    You get a text with a reply code. Nothing is dispatched until you reply YES with it.

Callers who mention a gas leak, sparks, or smoke are told to hang up and call 911. The assistant cannot transfer a live call to you, and it does not give repair advice.

Intake and urgency rules by trade

  • Plumbing

    Books a running toilet. Texts you about an active leak or a sewage backup instead of booking it.

  • HVAC

    Books a tune-up. Texts you about no heat or no AC instead of booking it.

  • Electrical

    Books an outlet that stopped working. Texts you about no power to the whole house instead of booking it.

The same call flow runs for elevator, garage door, appliance repair, roofing, pest control, pool, locksmith, landscaping, and general contractor businesses, each with its own intake questions and urgency rules.

Bay Area call patterns

The job mix and the questions callers raise change from one part of the Bay Area to the next.

  • San Francisco

    Multi-unit access, tenants calling about work a landlord pays for, and older building systems.

  • Marin County

    Long drives between jobs, and a county split between district water and wells and septic.

  • Sonoma County

    Routes that spread across the county, rural sites, and power-shutoff questions.

  • Napa County

    Wineries, restaurants, and tasting rooms where downtime costs money, alongside residential work.

  • East Bay

    Two counties, congested routes, and housing that runs from pre-war to new construction.

What to know before you set it up

Setup and call forwarding

The assistant gets its own number. Most owners keep their number and have their carrier forward the calls they miss: busy, no answer, or no signal. It cannot transfer a live caller to you. How forwarding works.

What scheduling needs

It offers times only inside the business hours you set, with a minimum notice and a booking horizon set for your trade (for most trades, at least two hours out and up to seven days ahead). Connect Google Calendar or Zoho Calendar so it sees your existing appointments. Without one, it books against your hours only.

After the call

A booked job goes on your connected calendar, with an email if you give us an address. Urgent requests come to you by text. A caller who turns down every offered time gets you a text and an email. One who hangs up before giving details gets you a text with their number, once your texting registration is approved.

AI and recording disclosure

Every call opens by saying the caller has reached an AI assistant and that the call is recorded, in English and in Spanish.

Your OK on urgent dispatch

Emergencies, and by default same-day requests, are not booked. You get a text with a short code; reply YES or NO with it. With no reply inside the response window (60 minutes for an emergency and 15 minutes for other urgent requests, unless we set a longer one for you), the alert expires. The approval step.

Try it before you commit

Call the plumbing demo line and play a homeowner with a leak: (415) 840-1592. Voice only. You will hear the owner hand-off described, but no text arrives.
