Non, dans la majorité des cas un simple réglage ou remplacement de ferrure suffit. Une fenêtre qui ferme mal a généralement un joint usé, une crémone déréglée ou un ouvrant affaissé — tous des éléments que nous réparons en intervention courte sans remplacer l'ensemble.

Oui, remplacement rapide. Nous démontons le coffre intérieur ou extérieur, changeons la sangle et l'enrouleur (encastrable ou pivotant selon le modèle), et vérifions la tension du tablier.

Trois causes principales sur BSO/raffstore : les texbandes (cordons d'échelle qui soutiennent les lamelles) se rompent avec le temps ; le moteur radio Warema perd l'appairage avec la télécommande ; la carte récepteur dans le coffre se détériore par infiltration. Nous diagnostiquons et remplaçons la pièce défectueuse.

Ne rien forcer : vous risquez de pousser le tronçon plus profondément. Nos techniciens disposent d'outils d'extraction spécifiques qui récupèrent le tronçon sans endommager le cylindre dans 90% des cas. Si le cylindre est endommagé, nous le remplaçons dans la foulée.

Oui, danger grave. Le symptôme 'la porte descend seule' est presque toujours le signe d'un ressort de torsion cassé ou détendu. La porte n'est plus équilibrée. Ne jamais retenir une porte qui descend : risque d'écrasement. Couper l'alimentation, laisser la porte en position basse, nous appeler.

Oui, à traiter rapidement sinon la structure complète peut s'endommager. Souvent ce sont les galets (roulettes) qui sont usés ou la crémaillère désalignée. Remplacement des galets, nettoyage et redressement des rails, réalignement de la crémaillère.
