What the Garonne leaves behind in a mechanism
Langon lives on the banks of the Garonne, and the low-lying parts of the town know what the river's floods look like. When the water goes down it leaves behind far more than mud: lasting damp in the timber, silt in the runners of a garage door, corrosion on the ironmongery and the padlocks of outbuildings. Cylinders close to the ground are the first to suffer. A mechanism that has been soaked cannot be rinsed out or freed up with oil: it has to be removed, checked, and replaced if it really did take on water.
Even without a flood, the air of the Garonne valley is enough to make joinery move. A timber door leaf swells in winter and shrinks in summer, the strike plate shifts, the bolt starts to bind. The usual reflex, pushing a little harder each week, is paid for sooner or later with a key snapped in the cylinder or a distorted rod linkage. So we look at the door first and only then at the lock: play in the frame, hinge height, position of the strike plates, condition of the threshold. A realignment often makes the replacement you thought was inevitable unnecessary.
The locks that take the most punishment, from the Friday market to country gates
The Friday market brings dozens of stallholders into the centre every week, right down to the banks of the Garonne. For the shops in the surrounding streets, that means a door worked non-stop, a shutter down and up again, a stockroom opened twenty times in a morning. Those are the closures that fail first, and rarely at a convenient moment. If you call about commercial premises, tell us the type of closure, its make if you know it, and the access arrangements: narrow street, cluttered pavement, back courtyard. That determines the equipment we bring.
Away from the centre, the front door is far from the hardest working one. The motorised gate opened four times a day, the up-and-over garage door, the side door onto the garden, the padlock on a shed along the route de Bazas: these are in constant use and almost never maintained. A roller out of line, a tired handle spring, a cylinder clogged with dust and greasy products can still be dealt with as a repair as long as only one component is at fault.
