Air off the jalles and timber that moves
Houses near the damp low ground and the edges of the woods live to the rhythm of changing humidity: early-morning fog, occasional frosts, heavy air for weeks on end. A solid timber front door, still common in the village centre and the old settlement cores, then swells by a few millimetres. You have to lift the door to lock it, one locking point catches, the key hunts for its notch. The symptom looks harmless in November; it becomes a full jam when the mechanism gives way under constant strain.
Sand and pine needles do the rest. Cylinders left fully exposed to the weather — main gate, pedestrian gate, garden shed, key safe — take dust, resin and driving rain without so much as a canopy to shelter them. A cylinder that catches in autumn will often seize with the first cold snap. Reporting these small signs early keeps the job down to a clean and a strike plate adjustment, whereas waiting for a full jam means far heavier work, and sometimes a replacement.
The locks you only use three months a year
On the large plots in Issac, Corbiac or Cérillan, some locks are only used in the warmer months: the back gate opening onto a footpath, the padlock on the shed, the up-and-over garage door, the door to the plant room. Six months standing still outdoors is enough for a mechanism to seize up. The repair then often involves less replacing than removing, cleaning, realigning and refixing a strike plate that the post or the frame has shifted as it moved with the seasons.
The centre and the newer blocks raise questions of a different kind. On a multipoint flat entrance door, a top locking point that refuses to engage almost always means rod linkage knocked out of adjustment by repeated slamming, not a dead mechanism. In the village houses, older surface-mounted locks mainly call for a check on parts availability before deciding between repair and replacement. In both cases the diagnosis is made on site, with the door open, and a detailed quote comes before the work.
