Frequently Asked Questions

Changes do not always show up in the same way. You might notice drafts, condensation, deterioration around the window, difficult operation, or a room that becomes uncomfortable during temperature extremes. If you are seeing those issues in your Decatur home, an in-home consultation can help you explore whether replacement makes sense and which options address your priorities.

Yes. Replacement does not have to mean changing what you like about your house. Renewal by Andersen offers double-hung, casement, sliding, picture, and other window styles, along with choices for color and other design details. Those options give you flexibility to work with the character of your home or make an intentional update where you want one.

Proper installation helps a replacement window or door fit, operate, and perform as intended. Renewal by Andersen Certified Master Installers are trained to work with our products, with attention to the details of the installation and care for the home while the work is underway. Installation is treated as an integral part of the complete replacement project.

Material stability, glass performance, and proper installation are all worth considering when temperatures vary substantially throughout the year. Renewal by Andersen windows use Fibrex® material, while energy-efficient glass options can be selected for the needs of your home. Together with professional installation, those choices support performance through changing seasonal conditions.

One local Renewal by Andersen team stays with your project from the initial consultation through the finished installation. That continuity gives you a clear point of contact if questions come up at any stage of the process.
