Delivery & warranties
01Where do you deliver?

Delivery is available throughout France. Your address and access conditions are checked before confirmation. The availability of measuring and installation services is confirmed for your site; installation is quoted separately.

Vérifier les services pour mon adresse
02What if I’m unsure about my measurements?

You can start with a configuration to plan your project. Final measurements must be approved before manufacturing. If you would like DEFIALU to take the measurements, select this service in the configurator or contact us for a price.

03Is the quote free?

Yes. You can view and download your quote free of charge. Where online acceptance is offered, a 10% deposit by card is required. This deposit is deducted from the total price; it is not a charge for the quote.

04How does payment work?

For full payment: bank card below €5,000 including VAT, or direct bank transfer from €5,000 including VAT. If you accept the quote with a 10% card deposit, DEFIALU will contact you to review the project. The remaining 90% is then paid by bank transfer after final measurements are approved and before manufacturing. Available payment methods and the amount due are shown before confirmation.

Consulter les conditions de vente
05When will I receive my windows and doors?

The standard manufacturing and home delivery time is 8 to 10 weeks after final measurements are approved and the order is definitively accepted, with full payment or approved and confirmed financing. Any specific lead time agreed in writing in your quote takes precedence. Installation follows a separate schedule.

Comprendre les délais et la réception
06Who should I contact about warranties or after-sales service?

DEFIALU remains your contact for windows and doors purchased on this website. Statutory warranties apply through the seller. The K•LINE commercial warranty complements them according to the product and components; its duration and conditions vary between components.
