  • Wij zijn heel tevreden over Cortina. De service is snel en professioneel. Ze nemen echt de tijd om je te helpen bij het maken van de juiste keuzes en raden zeker niet zomaar het duurste aan, maar wel wat het beste bij je past. Ook de plaatsing van de gordijnen verliep vlot en netjes. Bart en Krista zijn bovendien ontzettend vriendelijk en behulpzaam. Een aanrader!

    Review by Anneleen E. December 2025
  • Ik kan Cortina Tessenderlo alleen maar aanbevelen! Nadat ik in juli een mail had gestuurd, belde Bart me nog diezelfde dag terug – dat is nog eens snelle service!

    Diezelfde week kon er al een plaats bezoek doorgaan. Bart gaf zeer deskundig advies en had meer dan genoeg stalen bij zich om ons te helpen de perfecte, prachtige stoffen te kiezen. Je merkt direct dat hij zijn vak door en door kent.

    De samenwerking verliep enorm professioneel, en ook de plaatsing zelf is heel vlot gegaan.

    We zijn echt meer dan tevreden met het eindresultaat. Echt WAAAUW! Een absolute aanrader voor iedereen die op zoek is naar kwaliteit en topadvies.

    Review by Mira H. September 2025
  • In de winkel is er een enorme keuze aan elegante en tijdloze stoffen. Krista staat je professioneel bij in je keuze.

    Nu de raamdecoratie hangt, is het nog mooier dan ik me had voorgesteld. Het maakt het zo gezellig in huis en geeft een heel ander beeld.

    Bedankt Krista en Bart!!

  • Bart maakte vandaag van onze woonkamer een gezellig warme plaats met de juiste raamdecoratie. Kregen advies op maat voor onze woning en budget. We keren zeker en vast terug. Heel aangename mensen, correct en snel verloop van alles. Wij zijn zeer tevreden.
