In order for a window or door structure to fit perfectly into the desired opening, it is necessary to take the right measurements. Entrust this to a specialist whom our company will send to you when ordering products with installation. He or she will also be able to advise you on all your questions and recommend a particular package and configuration depending on your requirements and wishes. Remember that the correct measurement is 90% of the successful window and door replacement work. When ordering windows without installation, the customer can take measurements himself and we will manufacture the windows according to the provided dimensions.
