Frequently Asked Questions about Windows in Castellón

How much does window delivery to Castellón and Villarreal cost?

We are close to production bases, so delivery to Castellón, Vila-real, Burriana, and Vall de Uxó is very affordable. We often run promotions with free delivery when ordering glazing for an entire apartment. You pay for windows, not logistics.

Do you perform installation in Vinaròs and Benicarló?

Yes, our coverage area includes the entire coast and inland areas. Craftsmen arrive at the site fully equipped for "clean" installation. Installation is possible in residential apartments with minimal inconvenience to residents.

What to install on Costa del Azahar: salt or sun protection?

Both. Sea salt is aggressive to aluminum, so quality PVC is the best choice. Glass units should be multifunctional (heat protection), and hardware should have anti-corrosion coating. Roller shutters are also recommended for protection against summer heat.

What is the advantage of your warranty?

We provide an installation warranty, understanding the specifics of the region. The 10-year factory warranty protects you against profile color change and glass unit defects. This is more reliable than a warranty from a solo private craftsman.
