In the case of renovation, fitting consists either in the full replacement of the windows or in the application of the new window on the old casings.
This is the subject of particular attention: this is "TRYBA Trust Fitting":

• Committing ourselves in writing to keep to the fitting date,
• Fitting the windows carefully, efficiently, and according to the rules of the trade,
• Respecting your premises: protecting your furniture and the floor, cleaning up after the work has been done,
• Checking with you that the work has been carried out satisfactorily,
• Handing over the TRYBA warranty certificate to you.
