Missed call text-back and AI receptionist for builders

Calls you miss on the tools
Extension and renovation enquiries are big jobs, and people often ring several builders before deciding who to invite round. Missing that first call can mean missing the chance to quote.
Example calls, and how InstallerLine handles them
An extension enquiry
The call: A homeowner wants a single-storey rear extension and asks if you could come and look.
What InstallerLine does: Takes their details, the address and postcode, the kind of work and whether they have plans or planning permission, then pencils in a quote visit as provisional.
What you get: A summary and a provisional visit to confirm, move or decline.
When can you start?
The call: Someone asks how soon you could start a kitchen knock-through.
What InstallerLine does: Explains that you'll confirm timings yourself, takes the details and passes it to you. It never promises a start date.
What you get: An email and text so you can ring back with a realistic answer.
A sales call
The call: A marketing company rings trying to sell you advertising.
What InstallerLine does: Politely turns it away, so you're not interrupted.
What you get: Nothing to deal with, unless you'd like a note of it.

Hear a demo
📞 Call the demo line
The demo answers as a fictional heating firm, Borders Heating. Your line is set up for your own trade, with your services, area, hours and the questions you want asked.
Standard UK call rates apply. Calls to the demo line are recorded and transcribed so we can improve the service. Borders Heating isn't a real firm, so nobody will be sent out.

Questions from builders
Does InstallerLine work for builders?
Yes. We set it up for your firm: your services, area, hours, the questions you want asked and what counts as urgent. You approve exactly what it's allowed to say before it goes live.
Do I need to change my phone number?
No. You keep your number and divert calls you don't answer (or all calls, if you prefer) to your InstallerLine number. Your phone provider may charge for diverted calls, depending on your plan.
Does it confirm jobs on its own?
No. On Receptionist and Busy Firm it pencils jobs and visits into your diary as provisional, and nothing is final until you confirm with one tap or reply with another time. If you don't confirm within 24 hours (or 2 hours before the slot, if sooner), the slot is released and the caller is told you'll ring them.
Will callers know it's an AI?
Yes. It says so at the start of every call, and it tells callers the call is recorded.
Will it give callers a price or a start date?
No. By default it never quotes prices or promises dates. You can approve specific wording, such as how far ahead you're working, if you want it to.
Can it tell new enquiries apart from existing clients?
Yes. It asks, and your summary shows which is which, so existing clients don't get lost in the enquiries.
