How to Install Andersen Replacement Windows

Installing Andersen replacement windows can be a rewarding DIY project that can enhance the energy efficiency and aesthetic appeal of your home. Whether you’re replacing old, drafty windows or updating your home’s look, the process can be straightforward with the right tools and guidance. In this article, we’ll walk you through the steps to install Andersen replacement windows, ensuring a successful and hassle-free experience.

Step 1: Preparation

Before you begin, gather all the necessary tools and materials. You’ll need a tape measure, level, utility knife, screwdriver, drill, saw, putty knife, shims, and of course, the Andersen replacement windows you’ve purchased. It’s also essential to read the manufacturer’s instructions carefully, as specific models may have unique installation requirements.

Step 2: Removing the Old Windows

Start by removing the old windows. First, remove the interior stop molding to provide access to the window frame. Next, remove the interior sash, the part that moves up and down. Once the sash is out of the way, remove the exterior stop molding. Finally, carefully remove the old window frame, ensuring that you disconnect any electrical wiring or other components that may be attached.

Step 3: Insulating the Opening

Inspect the opening where the old window was installed. Clean out any debris and apply weather stripping or insulation around the edges to improve energy efficiency. Make sure the opening is level and square, as an uneven or misaligned frame can lead to installation issues.

Step 4: Installing the New Window

Position the Andersen replacement window into the opening. Make sure it’s level and plumb. Use shims to ensure a proper fit and to provide support. Once the window is in place, install the interior stop molding and the interior sash. Secure the window with screws provided by the manufacturer.

Step 5: Caulking and Finishing Touches

Apply a bead of caulk around the perimeter of the window to seal gaps and prevent air leaks. Caulk the interior stop molding and sash as well. Finally, reinstall the exterior stop molding and any other trim or hardware that was removed during the installation process.

Step 6: Final Inspection

After completing the installation, inspect the Andersen replacement window for proper fit and function. Check for gaps, leaks, and proper operation of the sash. Adjust the window as needed and make sure it opens and closes smoothly.

Installing Andersen replacement windows can be a satisfying DIY project that can significantly improve your home’s comfort and value. By following these steps and taking your time, you can ensure a successful installation and enjoy the benefits of your new windows for years to come.
