Two walls need a schedule.The rest need a habit.
Two kinds of wall
qualify — nothing else does
Walls the public stands in front of
Retail, a lobby, a control room that cannot go dark. A dark module is seen the same day — by someone who will tell you, and by everyone else.
Qualifies on · daily public use
Walls nobody can reach
A facade, a high mount, a wall behind glass. Getting to it is the expensive part — going up once with a plan is cheaper than twice in a hurry.
Qualifies on · access or criticality
Seven checks.The ones that catch a failure early.
Written for your own team
no tools you do not have
| Check | How often | What you are looking for | Who can do it |
|---|---|---|---|
| Module face scan | Monthly | Dead or stuck pixels, a module visibly brighter or duller than its neighbours | Anyone, from the floor |
| Brightness uniformity | Twice a year | A reading at three points of the wall, compared with the handover figure | Your technician, with a meter |
| Cabinet seals and glands | Twice a year | Hardened seals, a gland strained by cable weight, standing water in the tray | Your technician, on the structure |
| Power supply and fan | Quarterly | Supply temperature against ambient, a fan that has stopped or is noisy | Your electrician |
| Control path | After any change | Sender, cable and receiving cards still agreeing after a firmware or source change | Your technician |
| Fixings and torque | Annually | A module that moves when pressed, a fixing that has backed out | Your technician, on the structure |
| Corrosion at welds and fixings | Annually, outdoor | Surface rust versus section loss — the second one is structural | Structural engineer |
The two readings that matter most are brightness uniformity and supply temperature. Both drift slowly, both are cheap to record, and both turn a failure into a planned replacement instead of a dark wall on a Friday night.
You are not buying hours.You are buying a record.
Identical on every visit
Four things arrive after every visit.
- 01The readings. Brightness and colour measured, before and after calibration, with the meter named.
- 02The photographs. The sealed joints, the fixings, the parts that wear — dated.
- 03The list. What was fine, what is drifting, what to watch. Cheapest action first.
- 04The next date. Scheduled while we are still on site, not chased later.
What an inspection does not buy.Said plainly.
Three limits,
in writing
It does not buy emergency response
Visits are scheduled. If a wall is down now, that is Guidance — remote, free, and faster than anyone's travel.
It does not cover the other walls
An inspection is per wall, because a record is per wall. Additional walls are quoted, not assumed.
It does not renew itself
Nothing is auto-charged. The record stays yours either way — and so does the diagnosis history on it.
In one lineNothing on this page is a warranty. It is a schedule, a record, and a named person who already knows the wall.
The ones actually asked.
Answers apply
to every wall on the schedule
So what does an agent actually get?
Free inspection on every wall of yours we can reach while an engineer is already travelling your market — there is no fixed number of visits and no single-wall limit. Travel is ours. Parts and any trip that is not already happening are quoted first.
What if a single visit finds nothing wrong?
Then you get a report saying so, with the readings that prove it — that is a useful document to hold. You are paying for the measurement, not for a fault, and a clean visit still sets the baseline the next one is compared against.
Can we start with one visit and buy a contract later?
That is the usual order. The single visit produces the report the contract is priced from — size, access, condition and how often the wall actually runs. Nothing is priced off a datasheet.
Tell us the wall.We will tell you what to look at first.
Sometimes the honest answer is no schedule needed — a small indoor wall with a competent local team is fine on its own. We will say so and tell you what to watch.
