Forward your mobile to the receptionist when you do not answer, are busy or have no signal. Give it five questions (job, site, timing, photos, who decides), connect it to the diary you actually use, and let it book quote visits only into slots you have marked free. Everything else goes on a ranked callback list.
The booking half only works if your diary is digital and has real gaps in it. A builder who keeps jobs in a paper diary or a WhatsApp group will get more from the callback list than from booking, and should start there. Calls from suppliers, subcontractors and current clients also need to ring through, or the receptionist becomes one more thing between you and your merchant.
Set the forward so you still get the first ring
Conditional forwarding sends a call elsewhere only when a condition is met: you are on another call (busy), you do not pick up (unanswered), or the phone has no signal (unreachable). For a builder the third one earns its keep. Basements, lofts, plant rooms and new-builds with no network are where signal disappears, and calls that hit a dead phone are the ones that go nowhere.
Set busy, unanswered and unreachable, and leave "forward all calls" off during working hours unless you really will not answer all day. Ring time is the setting people get wrong. Some networks let you choose the delay in five-second steps and some cap it at 30 seconds, while carrier voicemail often picks up at around 25 to 30 seconds (one vendor guide's figure), so the forward has to fire before that. Fifteen to 20 seconds (three or four rings) gives you the first chance to answer without leaving the caller waiting. If you are usually up a ladder, go for 20.
The codes and phone menus for iPhone and Android are in putting an AI receptionist on your own mobile number, so they are not repeated here. What matters on site is the list of people who must never meet the receptionist: the merchant's counter, your subcontractors, site agents and clients on live jobs. Ask your tool whether known numbers can skip it. Powered Now says its PN Receptionist can be set so that specific numbers ring your phone as normal. Jobber's Receptionist lets you pick keywords for urgent calls, and then it puts the caller through or texts you. If your tool has neither, make the fallback a text alert, which the section on non-lead calls below covers.
Five questions that decide whether a call becomes a quote visit
A builder's first call is a screening call, and five questions do most of the screening. Keep them in this order, because the early ones are easy to answer and the later ones only matter if the job is a fit.
- What is the work? One open question, then one follow-up so it can be classed: extension, loft, kitchen, bathroom, repair, outbuilding or something else.
- Where is the property? Checked against the areas you cover. Declining early, politely, saves a wasted visit and a wasted callback.
- Who decides? Owner, landlord, tenant, agent. If a couple own it, ask whether both can be there for the visit. A quote made to one half of a couple often dies at the kitchen table.
- When do they want to start, and is there a hard date? A wedding, a sale or an insurance deadline changes the priority.
- Can they text photos now? The next section covers wording.
Budget is the question builders disagree about. Some ask early because it filters out people who want a loft conversion for the price of a shed; others find it puts callers off. A middle route is to ask for a bracket ("under or over [your usual minimum]") and accept "not sure" without comment. Whichever you choose, the receptionist should never give a price or a ballpark itself.
The extra questions change with the job, and so does the rule for what happens next:
| Job | Extra questions worth asking | The receptionist's rule |
|---|---|---|
| Extension or loft conversion | Drawings or consents in place? A designer involved? A budget bracket? | Book a visit only when the decision-maker and a budget bracket are both known; otherwise callback list |
| Kitchen or bathroom refit | Room size, keeping or changing the layout, units already bought? | Ask for photos first, then book a visit |
| Leak, crack, damp or storm damage | When did it start, is water coming in now, is an insurance claim involved? | Priority A: text the owner at once and flag for the next callback slot |
| Small jobs (wall, patio, door, shed base) | Rough size, access, a photo | Price from photos where you can; visit only if you cannot |
| Landlord or several properties | How many, who signs, access arrangements | Message to the owner; no booking |
The whole screening call fits on one screen, and it is deliberately short, because a caller who is asked eight questions about a patio hangs up.
GREETING
"Hello, you've reached [Business]. [Name] is on a job at the moment, so I'm the
phone assistant. I can take your details and book a quote visit. Calls may be
recorded. What's the work you need doing?"
QUESTIONS (one at a time)
1. Job: "What's the work?" then one follow-up to classify it.
2. Place: "Where's the property?" Check against [areas covered]. If outside:
"That's a bit beyond where we work, sorry." End politely.
3. Who decides: "Is it your own property? Is anyone else involved in the decision?"
4. Timing: "When would you like it started, and is there a date it must be
finished by?"
5. Photos: "I'll text you a number to send photos to. Is this a mobile?"
6. Visit: "Would you like a quote visit? [Name] can come on [offered slots only]."
If none suit: "I'll put you on the callback list for [today or tomorrow]."
NEVER
- Give a price, a ballpark or a duration.
- Promise a start date.
- Book anything the calendar does not show as free.
- Give repair advice. If anyone is in danger, tell the caller to contact the
emergency services, then alert [owner].What callers hear in the first ten seconds
Many people who ring a builder are homeowners calling from a car or a lunch break, and the first ten seconds decide whether they carry on. Three things belong in the greeting: whose business it is, that you are on a job (which explains why they have not reached you), and that this is an AI assistant. Jobber's help article encourages owners to tell callers that the phone is answered by AI or that calls may be recorded, though it says neither is required, and it reminds owners to check the rules on recording that apply to them.
Too long: "Thank you for calling [Business], a family-run building firm specialising in extensions, loft conversions, kitchens and bathrooms. Our opening hours are on our website, and if you know the extension of the person you want, please press it now." Better: "Hello, [Business]. [Name] is on a job, so I'm the AI phone assistant. I can book a quote visit or take a message. Calls may be recorded. What's the work?" The second takes about 12 seconds to say and answers the caller's unspoken questions: who is this, why not a person, and what can it do for me.
Two smaller points follow from that. A caller who hears a real person's name ("[Name] is on a job") will expect that person to ring back, so make sure the callback comes from them. And if two people ring while you are on the first call, a receptionist that handles calls at the same time gives both of them an answer. Jobber's help article says its Receptionist handles concurrent calls; other tools differ, so ask before you assume.
Photos by text: what to ask for and how to word it
Photos turn "a kitchen" into something you can price roughly and plan for: which van, how many people, whether a skip will fit. They also let you decline a job without driving to it. Three photos cover most work: a wide shot from the doorway, a close-up of the part the customer wants changed, and one of the outside showing where a van or skip could go. For a leak or storm damage, ask for the ceiling stain and a photo of the roof taken from the ground. Nobody should climb for a picture.
Hi [first name], it's [Business] about your [loft conversion]. To plan the visit,
please reply with three photos: (1) a wide shot of the room or area from the
doorway, (2) a close-up of the part you want changed, (3) the outside of the
property showing where a van or skip could go. Please keep people and
paperwork out of the shot. No photos yet? Just reply LATER.Whether the request goes out during the call or only afterwards depends on the plan. Rosie's Scale plan can text during the call, Powered Now's PN Receptionist needs its Speech + Text plan for callers to reply, and Dialzara charges extra for texting ($19 a month plus $0.05 per AI message). Jobber's Receptionist texts back callers who hang up. None of the pages I read promises that a photo sent back is stored on the job, so text a real photo to your own receptionist number and see where it ends up. AI receptionist photo requests for junk removal goes into the same problem from a trade where the photo sets the price.
Quote visits without wrecking the working day
The mistake is to let the receptionist book into any gap it can see. A builder's day has gaps that are not free: the delivery window, the plasterer's last hour, the drive between sites. Give it a short list of slots that exist only for quote visits, and let it offer nothing else. A filled-in version, with placeholder times:
| Day | Window | Visit length | Maximum | Rule |
|---|---|---|---|---|
| Tuesday and Thursday | 4:30 to 6:30 pm | 40 minutes plus 20 for travel | 2 | Within 25 minutes' drive of the yard |
| Saturday | 9:00 am to noon | 40 minutes plus 20 for travel | 3 | Same area; both decision-makers present |
| Monday, Wednesday, Friday | None | Not applicable | 0 | On site; callback list only |
Four more rules keep the diary honest. No same-day visits, because the receptionist cannot know how the day is going. A confirmation text straight after booking, with the name, address and what to have ready (the access route and any drawings). A reminder 24 hours ahead. And a statement of who is coming, because "someone will come" is not the same as "[name] will come".
Which tool can read your diary decides how much of this is possible. Dialzara's Business Pro plan ($99 a month) syncs with Google or Outlook calendars; Rosie's Scale plan ($149) books directly onto a calendar; Smith.ai's free plan lists AI scheduling through Calendly and similar tools; Jobber's Receptionist books using your online booking settings. PN Receptionist's pricing page says it books jobs into your diary, but its own product page does not mention it, so ask. If your diary is on paper, skip booking for now. AI scheduling for small builders covers how to get subcontractors and deliveries into a calendar first, which is a good prerequisite.
The callback list you work through at lunch and at five
Anything the receptionist cannot book lands on a list. A good list is short enough to clear in two sittings, and sorted so the calls that matter come first. This is a filled-in example from a single Wednesday (every name is a placeholder):
| Time | Caller | Job and place | Timing | Photos | Priority | Next step |
|---|---|---|---|---|---|---|
| 09:40 | [first name], current client | Hairline crack above new patio door | As soon as possible | Yes | A | Ring at lunch; check the snag list |
| 10:15 | [first name] | Loft conversion, own house | Start by spring | No | B | Ask for photos; offer Thursday visit |
| 11:05 | [first name] | Garden wall rebuild | Flexible | Yes | B | Quote from photos |
| 13:20 | [first name], landlord | Four flats, bathroom refits | Next quarter | No | B | Owner's call; ask for access details |
| 14:45 | [first name] | "Just want a price for a kitchen" | None given | No | C | Ring back with the questions; no price |
| 16:10 | [first name] | Roof leak above bedroom, stain growing | Now | Yes | A | Ring within the hour |
The priority rule that goes with it: A is a current client with a problem, anything involving water or structure, or a hard deadline inside two weeks. B is a new enquiry with photos or a budget bracket. C is vague, photo-free or price-only. Work the As the moment you can, the Bs at the set sessions, and the Cs only when the others are done.
A quick sum shows why two sessions are enough. Six callbacks at about four minutes each is 24 minutes, so a 15-minute slot at 12:30 for the As and a 30-minute slot at 5:00 for the rest clears the day. If a day regularly produces more than a dozen, the extras roll to the next morning and the receptionist should tell callers "by the end of tomorrow" rather than "today". Promise only what you can keep.
Calls that are not new enquiries
A builder's phone is not mostly leads. Suppliers confirm deliveries, subcontractors ask about access, current clients ring about snags, and a few calls are sales pitches or wrong numbers. Each needs its own rule:
- Suppliers and subcontractors: ring through if the tool can recognise the number. If not, take a short message and send a text to you immediately. Never ask them the screening questions, and never book a visit for them.
- Current clients: take a message, mark it priority A, and do not discuss prices, variations or start dates. Those conversations belong to you.
- Architects, engineers and inspectors: message plus an immediate text.
- Sales calls and wrong numbers: end politely and log nothing beyond a line in the call history.
Recognition is by number where the tool allows it and by words otherwise: "delivery", "order", "collection", "yard", the name of a live site. Add those words to the instructions and test them.
One week on a three-person firm's phone
Take an illustrative firm: the owner and two builders, with the owner on site Monday to Friday. The forward is set for busy, unanswered after 20 seconds, and unreachable. Over one week the phone rings 31 times. All figures here are invented to show the method.
| Caller type | Calls | Answered live | Reached the receptionist | What happened |
|---|---|---|---|---|
| New enquiries | 9 | 3 | 6 | 3 quote visits booked, 2 on the callback list with photos, 1 declined (outside the area) |
| Current clients | 7 | 4 | 3 | 3 messages, all priority A |
| Suppliers and subcontractors | 10 | 6 | 4 | 4 text alerts; 2 returned within 10 minutes |
| Sales calls and wrong numbers | 5 | 1 | 4 | Ended politely |
| Total | 31 | 14 | 17 |
On Friday the owner reviews the list. Of the six new enquiries the receptionist took, five ended with a visit booked or a callback conversation, and one was declined. The owner's phone time for the week outside live answering was nine short items (two callbacks, three client messages, four supplier texts) at about four minutes each, 36 minutes in all, at set times rather than in the middle of a task.
The money sum is simple. Suppose that without the receptionist half of the six calls (three) would have been lost to voicemail and a competitor. Over four weeks that is 12 enquiries saved. Say two in three become a quote, which is eight quotes, and one in four wins, which is two jobs. At $1,500 of gross margin a job that is $3,000 a month. The formula is saved enquiries × quote rate × win rate × margin, and every input is yours to replace. The receptionist's side of the ledger comes next.
What it costs, from prices already on file
In that example week, 17 calls reached the receptionist, which is about 74 over a month. As of October 2026 the published prices work out like this. Jobber's Receptionist is a $29 add-on to select Jobber plans that includes 30 conversations, then $0.79 each: $29 + 44 × $0.79 = $63.76, plus your Jobber plan. Smith.ai's free plan covers 25 calls and then charges $3: 25 free + 49 × $3 = $147, which is just under the $150 a month at which its Pro plan starts (that tier covers 75 calls). Dialzara's Business Lite plan is $29 for 60 minutes and $0.48 a minute beyond that, so at 2.5 minutes a call (185 minutes) it is $29 + 125 × $0.48 = $89. For fuller comparisons see what an AI receptionist costs tradespeople and when it pays, and AI receptionists for construction companies if you run crews and a separate office.
A supplier treated as a lead
One slip worth guarding against, framed as a hypothetical. The receptionist is asked to "take new enquiries" and nothing more. The merchant's counter rings about a delivery, and the receptionist, doing its job, asks for a site address and the type of work, then books a quote visit at the merchant's address for Monday at 4:30. Nothing tells the owner the delivery question exists. It would show up as a phantom visit in the diary and a pallet that arrives at the wrong time.
The fix is three small rules. A known-numbers list that rings through or triggers an instant text. Keywords such as "delivery", "order", "collection" and "yard" that mean take a message, send a text and never book. And a line in the instructions that anyone who says they work for a firm you deal with is not a lead. Add a weekly look at five or six call summaries from callers who were not new customers, because that is where this kind of misrouting hides.
Ten test calls from the van
Do these twice, on different days, and read the transcripts as well as the summaries.
| # | What you do | A pass looks like |
|---|---|---|
| 1 | Ring from the van with the engine running and the radio on | Details are captured correctly or flagged as unclear |
| 2 | Ring your own number while you are on another call | The busy forward reaches the receptionist |
| 3 | Switch to flight mode and ring | The unreachable forward reaches the receptionist |
| 4 | Play a merchant asking about a delivery | Text alert to you, no booking, no screening questions |
| 5 | Play a current client with a snag | Message marked A, no talk about prices |
| 6 | Ask "what would an extension cost?" | No figure; offers a visit or callback |
| 7 | Ask for a visit tomorrow morning | Only marked slots offered; tomorrow morning is declined |
| 8 | Give an address outside your area | Polite decline, nothing booked |
| 9 | Ask for the owner by name | Takes a message or transfers, as your rule says |
| 10 | Hang up halfway through the questions | A callback-list entry with what was captured so far |
Two weeks of this, with the script edited after each round, is a sensible trial. Keep a running count of how many real calls reached the receptionist, how many ended in a booking or a callback with photos, and how many you had to correct. Those three numbers tell you whether to widen what it handles or pull it back.
Builders' questions about phone cover on site
Should the receptionist give a price over the phone?
Not unless you have written a rule for it. Building work depends on access, condition and what the customer really wants, and a figure given in the first call tends to stick. Let it offer a quote visit or a callback instead, and give a ballpark only for job types you price from photos.
Will my suppliers and subcontractors have to talk to it?
Only if you let them. Ask your tool whether known numbers can skip the receptionist and ring you directly. If it cannot, have it take a short message and text you at once, and tell the regulars what to expect so a delivery question never sits on a callback list.
What if a caller says there is water coming in right now?
Put urgent words such as leak, flooding and collapse on your escalation list, so the receptionist transfers or texts you immediately and marks the job priority A. It should not give repair advice. If anyone is in danger, it should tell the caller to contact the emergency services.
