"The handle goes floppy and the door won't lock"
That is the whole description on the enquiry. It could be a snapped gearbox, a worn handle spring, a failed cylinder cam or something else entirely, and the fix depends on which mechanism is in the door. So the engineer books a visit, takes the edge of the door apart, measures the backset and centres, notes the brand stamped on the faceplate and goes away to order the part. The customer pays a call-out for a visit that fixed nothing. The engineer loses a slot.
Sometimes the customer did send a photo. It was of the handle from a metre away, taken at night, which tells you the colour of the handle and not much else.
Customers don't know what you need to see
The information that decides the part is on the edge of the door, on the faceplate and in a few measurements. Customers do not know that. They photograph the part that looks broken. Nobody asks them for the right pictures in a way they can follow, so the photos that do arrive come in by WhatsApp, text and email, loose from any job record.
- Enquiries arrive with a vague symptom and no photos.
- When photos arrive, they show the wrong part of the door.
- Photos come through personal phones and messaging apps, not the job system.
- Measurements are not asked for, or are given in the wrong places.
- Engineers identify parts in their heads from memory, so the knowledge is not shared.
Two visits where one would do
The first visit on a uPVC repair often exists only to gather information. It is a slot that could have been a paying job, fuel and travel on a busy day, and a customer who waits longer than they expected for a working door. Some customers decide the first call-out was money wasted and do not book the second.
There is also the counter-risk: an engineer who guesses from a bad photo, orders the wrong gearbox and ends up making three visits.
A guided photo request, attached to the enquiry
We build a short guided flow that the office sends by text or email as soon as a non-emergency uPVC enquiry arrives.
- The customer gets a link that opens in their phone browser, with simple illustrated steps: open the door, photograph the whole edge, then the faceplate close up, then the handle and the cylinder.
- Each step shows an example of a good photo, so the customer knows what you mean.
- For measurements, the flow asks for the few that matter, with a picture showing where to measure, and accepts "I can't" as an answer.
- Photos and answers attach to the enquiry in your job system, or in a simple enquiry board, rather than sitting in a messaging app.
- The engineer or office reviews them and chooses the likely mechanism from your parts list. If the photos are not enough, the enquiry is marked for an inspection visit instead.
- Where you want it, an AI image model can suggest a likely brand and type from the faceplate photo, shown only as a suggestion for the engineer to confirm.
| Photo asked for | What it tells the engineer |
|---|---|
| Whole door edge | Mechanism type, number of locking points, hooks or rollers |
| Faceplate close up | Brand stamp and model markings |
| Handle and cylinder | Handle style, finish, cylinder type |
| Measurement guide | Backset and centres for ordering |
| Frame and keeps | Whether keeps need replacing too |
The engineer always has the final word. If they cannot be sure, they say so and book an inspection. The point is to make the first visit the fitting visit whenever the photos allow it.
More first visits that fix the door
Parts are ordered before the booking, so the visit is the repair. The office can quote a firmer price because the part is known. Customers feel they are being dealt with properly, because the first contact is a clear set of instructions rather than "we'll need to come and have a look".
Over time the photos and the parts actually fitted build a reference library of mechanisms your area has in its doors, which helps new engineers learn faster.
Is this a regular problem for you?
- Many uPVC repairs take one visit to identify and another to fix.
- Customer photos arrive by WhatsApp and are hard to find later.
- Customers are rarely asked for specific photos or measurements.
- Engineers sometimes order the wrong mechanism from a poor photo.
- Only your most experienced engineer can identify parts from a picture.
