Households in Longmoor mostly need three things from us over the life of a door: a tune-up now and then, a spring or cable when one lets go, and a new opener or door when the old one is finished. Every one of those, plus the smaller jobs between, is covered below.

Every square is one home in a hundred.
Whichever the fault calls for. A worn or broken cylinder in a handle that is otherwise sound is swapped or rekeyed on its own. A handle that is cracked, corroded through or of a pattern with no parts available is replaced as a set with its spindle and inside turn handle. The technician shows you what has failed before either route is taken.
It depends, and not reliably. The other cable and its spring may hold that corner so the door tips and wedges in the track rather than falling square, and the rollers binding can add some resistance, but neither is dependable: the door can still drop unexpectedly on the failed side. Some doors also carry a broken-cable device on the bottom bracket that grips the track if a cable fails. Because the door may not be held at all, the technician clamps and supports it before doing anything else.
Low-headroom garages use a different arrangement: the spring assembly may be mounted at the rear of the horizontal tracks, or special low-headroom drums and track bring the door up with less clearance. Replacement follows the same principles, but the drums, cable routing and turn count differ. The technician identifies the system on arrival and brings hardware that suits it, so the door balances correctly in the space available.
Yes. The last steps of the visit are the balance test by hand, several full cycles under power and the opener's reversal checks, so the door is ready for normal use when the technician leaves. New springs need no settling period. It is worth running it yourself once or twice while the technician is still there, so you know what a properly balanced door sounds and feels like from now on.
