J’ai récemment fait appel à Net Habitat Genève pour l’entretien complet de ma toiture et je suis pleinement satisfait du résultat. L’équipe a été ponctuelle, professionnelle et très attentive aux détails. Le nettoyage a été effectué avec soin, et ils ont pris le temps de vérifier l’état général du toit, en me donnant des conseils utiles pour prolonger sa durée de vie. Leur travail est impeccable, et j’ai vraiment apprécié leur transparence et leur sympathie. Je recommande vivement Net Habitat Genève à toute personne souhaitant un service de qualité pour l’entretien de sa toiture.
