The problem
Plastering is the least interruptible trade there is. Once a coat is on, the clock is running. Stop to take a call and you see it in the finish. The phone isn't a choice you get to make.
Three things follow from that:
- It rings, and you carry on. Every time, on every job, for the whole of the working day.
- The work puts you where phones don't reach. Boarding out a plot, working between floors, a garage conversion with no signal. Calls don't even show as missed until you come out.
- You can't tell what you missed. A homeowner with a room to skim and a main contractor with a development's worth of work look identical on a list of unknown numbers.
Voicemail doesn't sort it out either. Most callers don't leave one, and the ones who do leave a name and a fragment.
The calls you miss
Float and hawk in hand, mid-skim. Stop mid-coat and you see it in the finish. A homeowner rings about re-skimming three bedrooms after a damp repair. You can't pick up. They ring the next plasterer on their list and book him instead.
On a new-build site with no signal. You're boarding out a whole plot and the signal cuts out between floors. Three missed calls stack up by lunchtime. By the time you ring back, two have already moved on.
Finishing a garage conversion, dusty and tired. A main contractor rings about ongoing work across a development. You're in the last hour of a long day and you let it ring through. That's a recurring commercial relationship you nearly missed.
Sunday morning. A property developer has seen a survey flagging hairline cracks and wants a plasterer before the sale completes. They ring at 9am. No one picks up and they try an emergency plastering service they find online.
How Telphi answers for a plasterer
A plastering enquiry can be a single-room skim or a full re-plaster after a flood. Telphi's questions scope it quickly.
Caller: "Hi, I'm looking for someone to re-plaster after we've had some water damage."
Telphi: "Of course. Can you tell me roughly how many rooms are affected?"
Caller: "Two rooms – the living room ceiling and one bedroom wall."
Telphi: "And has the damp source been fixed, or is work still ongoing?"
Caller: "Yes, the leak's been sorted. The plumber signed it off last week."
Telphi: "Good. Are the surfaces bare brick or block, or is there existing plaster that needs coming off first?"
Caller: "There's old plaster still on – it's blown in a few places."
Telphi: "Understood. And where are you based?"
Caller: "Peterborough, PE3."
Telphi: "Perfect. I'll pass this over and someone will be in touch to arrange a look at it. Can I take your name and best number?"
You get a summary: water damage re-plaster, living room ceiling and one bedroom wall, blown existing plaster to hack off, damp source resolved, Peterborough PE3. You ring back with a clear picture of the job and a realistic idea of the day rate involved.
For new-build or developer work, Telphi asks about plot numbers, boarding schedule, and whether the work is part of a first or second fix programme. For insurance work, it asks whether a loss adjuster has already approved the scope.
What you get after every call
After each conversation, Telphi sends you:
- A written summary of the work described, number of rooms, surface condition, location, and any timeline pressure
- A full transcript of the conversation
- A call recording to listen back before you visit
- An urgency flag if the caller has a hard deadline – completion date, insurance claim deadline, or tenant moving in
Sales calls and irrelevant enquiries are filtered before anything reaches you.
If a call comes in mid-job that genuinely can't wait – a main contractor with an on-site problem needing an immediate decision – Telphi transfers it directly to your phone before the conversation ends.
Booking
After the qualifying questions, Telphi texts the caller a booking link. They pick a time for a site visit or call-back directly from your live calendar. You turn up having already read the job details. They turn up knowing they're confirmed. No double-booking. No chasing missed calls on an evening.
Trade businesses lose an estimated £1,200–£4,800 per month to unanswered calls. For a plasterer with a full diary, that's the difference between turning work away on your terms and losing it to the next number on Google. That estimate is based on typical UK trade job values and a 20–30% call conversion rate. Work out your own number.
