L'évacuation de mon évier de cuisine a été déboîtée du mur à 16h un vendredi par la pression des conduits, causée par un bouchon dans le mur. Ils ont été en mesure de m'envoyer en une demi-heure deux plombiers très pro qui ont passé presque une heure à déboucher un mètre de bouchon bloquant l'évacuation centrale des conduits de cuisine de mon immeuble, avant de réparer mon évacuation. Ils ont même été vérifier chez mes voisins que le bouchon n'avait pas fait aussi du dégât chez eux. Merci à eux et à leur travail en urgence mais soigneux. Plus de fuite et un évier fonctionnel avant le week-end !

Top, résultat final impeccable, un travail d'une très grande qualité et précision, de belles finitions soignées, beaucoup de bons conseils, matériel de qualité, que ce soit les murs de notre salle de bain ou tout notre sol, nous sommes ravis et vous recommendons chaudement.
