A new replacement window must fit well in the opening to provide long-term performance and energy efficiency. Renewal by Andersen® replacement windows are custom made to precisely fit each window opening in your home, and they are installed by professional Renewal by Andersen installers.Improper installation can easily occur if an installer cuts flashing incorrectly, uses the wrong sealant or does not insulate between the window and rough opening. Rough handling during transportation or installation can compromise the seal of the glass to the frame. Any of these things and more can keep your window from performing to the product’s fullest performance level. Further, if the area of the window is not measured properly, the wrong size window will be made.Renewal by Andersen focuses on the big-picture: the whole window performance. We pay particular attention to the window frame and glass- critical components for energy efficiency. We also place enormous significance on complete professional installation, and warrant it in writing- because a good window can only perform well if it’s installed correctly.We consider installation so important to a window's performance that we back it in a written limited warranty.
