Frequently Asked Questions about Windows in Gipuzkoa

Is there window delivery to San Sebastián, Irún, and Eibar?

Yes, the Basque Country is an important destination. We deliver windows to San Sebastián, Irún, Errenteria, and Eibar. Vehicles are equipped for safe glass transport. By ordering from us, you receive goods directly from the factory at the best price.

How to order installation in Gipuzkoa?

Submit a request, and we will send a craftsman to Zarautz or any other city. Given the rainy climate, we use installation technologies that ensure maximum seal tightness at junctions.

Which windows will handle the rain and wind of Gipuzkoa?

The main requirement is water resistance and wind resistance. We recommend premium-class systems (Rehau Synego, Kömmerling 76) with three sealing contours (MD). They reliably protect against drafts even in storms.

Who is responsible for the warranty?

We work with the best European factories, which provide 10 years warranty on profile and glass units. Our company is responsible for installation. If there is a leak or draft, it is our responsibility, and we will fix it.
