Never miss another after-hours service call.

Every call you miss goes to the next company on the list.
Homeowners with no heat or a leaking pipe don't leave a voicemail and wait. They hang up and call the next result. You paid for that call with ads, reviews, and years of reputation.
-
After hours, it rings into voicemail
Nights, weekends, and holidays are when emergency jobs come in.
-
During the day, your crew is on the tools
Nobody can take down an address from a crawlspace or a roof.
-
Answering services just take messages
Someone still has to call back, and by then the customer has booked someone else.
-
Your on-call tech gets woken up for routine calls
A tune-up request at 1 a.m. shouldn't ring the same phone as a gas leak.
From first ring to booked job, without you picking up
Forward your calls when you want SyntexBuild to answer: after hours, when you're busy, or all the time.
Answer
Greets callers with your company name and tells the caller it's an AI assistant.
Triage
Gets the name, phone, address, problem, and urgency, and spots emergency language.
Book
Checks your availability and captures the appointment request with every detail.
Dispatch
Puts the job in your dashboard and technician app, or transfers to a person when it should.
A receptionist that never sleeps, and a fallback that's always a person
24/7 answering
Nights, weekends, long weekends, and the first cold snap of the year, when every line rings at once.
Emergency escalation
Gas, CO, smoke, sparks, flooding, or your own emergency phrases trigger an immediate transfer to your on-call number.
Real bookings, not messages
Appointment requests are captured against the availability you configure, with the full job context attached.
Human handoff on request
Callers who want a person, or calls the AI isn't confident about, go to the number you choose.
Dispatcher dashboard
Bookings and job details in one place, so your office starts the morning knowing what came in overnight.
Technician app
Your techs see their schedule, customer details, and job notes on iOS and Android.
It knows what it shouldn't handle.
Your reputation is on every call. SyntexBuild follows strict rules: it takes the details and leaves the expertise and the judgment calls to your team.
It always:
- Says it's an AI
- Tells callers in danger to get safe and call 911
- Transfers emergencies to your on-call tech
- Hands off to a person when asked
It never:
- Diagnoses equipment
- Gives repair instructions
- Promises a home is safe
- Pretends to be a person
