Get a spray bottle, put a squirt of washing up liquid in it, wet the valve and watch. If a fine froth grows where the rubber meets the rim, or around the little core in the middle, then your puncture is not a puncture. Snap-in rubber valves go hard with age, heat and the chemicals in wheel cleaner, and once the base stops sealing the tyre gives up two or three pounds a week with absolutely nothing in the tread to find.
It catches out a lot of people who have already spent an evening running a hand over the tread hunting for a nail. It is also why the valve gets renewed as a matter of course whenever a tyre comes off the rim: the part costs pennies, it takes a minute, and leaving an eight year old one in place undoes the repair you have just paid for. If the leak does turn out to be a nail after all, the wheel is off and the proper repair follows on straight away, at whatever hour you rang.
The useful thing about an overnight repair is what it saves you the next morning. We do the second, across UB1, 24 hours a day and every day of the year. Driveways in Southall town centre, side streets and supermarket car parks are all normal working ground at three in the morning. The the Western Road area phone and the Norwood Green phone ring the same fitter, any hour. Midnight in Norwood Green, midday in Dormers Wells, the same call either way.

The main roads never really get a quiet hour, but the side streets do, and that is when a wheel can come off without a queue forming behind us. Around Southall Green the parking is packed tight enough that a daytime job usually means somebody waiting on you to finish. Overnight the car is already still, nobody needs to squeeze past, and the tyre is ready before the morning.
Air every week, nothing to see in the tread, and a tyre that is soft again by the weekend. That pattern points at the valve or the bead far more often than it points at anything stuck in the rubber.
Sensor valves are aluminium and they corrode where they pass through the wheel, particularly on a car that has seen a few winters of road salt. They weep slowly, and the dashboard light is the first anyone hears of it.
Night is the one part of the day when the car is blocking nobody and there is finally room to work alongside it. Sorted then, it is ready long before you need to be anywhere at seven.
Yes, as standard, unless yours is a sensor valve in good order, in which case it gets a new seal and collar instead. It is the cheapest part of the entire job and the one most likely to bring you back out.
It might be. The light only reports low pressure or a sensor that has stopped talking, and it cannot tell you which. We check the pressures, look hard at the valve, and go from there rather than assuming the sensor has died.
Nothing at all. Compressor, lighting and everything else travels on the van, so there is no lead trailing through a window and no bucket to fill. All that is needed is enough room to get alongside the wheel.
No. The machine is quieter than a diesel idling, nuts come off with a bar rather than an air gun wherever possible, and the work lamp points down at the wheel. Neighbours generally sleep through it.
Not if we can get at it. Some people unlock it and go back to bed. Others would rather stand and watch, which is fine, and it is the quickest way to see for yourself what came out of the tyre.
