What makes Cortina different?

Personal advice, Belgian quality, our own fitters

At Cortina, our advice goes beyond the prettiest fabric. We think about function, such as privacy, daylight and sound, and about your interior style. The result doesn’t just look right, it works every day.

We work with the best Belgian brands, for a long life and an excellent finish. And because we fit everything ourselves, without subcontractors, you always know who to turn to.

  • 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.

  • 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.

Questions about window treatments

How does buying window treatments from Cortina work?

In four steps. First we get to know each other: in the shop, by phone or in an online call. Then you choose fabrics and systems, ideally with samples at your home. Next we measure everything precisely and you receive a clear quote with no hidden costs. Finally our own team fits everything neatly.

Do you come and measure at home?

Yes. Once you have made your choice, we visit for a technical measurement. That way everything is made to the exact size of your windows.

Do you fit yourselves, or do you use subcontractors?

We fit ourselves, with our own team. Bart, a trained joiner, mounts the tracks and systems. We do not use subcontractors.

Which brands do you work with?

With Belgian brands such as Diaz, Verdeco, BM Fabrics and Pieters Vandevelde, known for quality and a long life.

What do made-to-measure window treatments cost?

That depends on the system, fabric, dimensions and operation. After measuring you receive a transparent quote. We don’t simply recommend the most expensive option, but what suits you and your budget best.

Can I see samples at home?

Yes. We bring samples to your home, so you can see how a fabric falls and how the colour looks in your own light.

Can you motorise blinds and curtains?

Many of our systems are also available motorised, with a remote control or an app. We look together at what is technically possible for your windows.
