8 Easy Steps on How to Replace a Aluminum Window

Step 1: Remove Old Window

The first step in replacing your aluminum window is to remove the old one. Start by removing the interior trim and the storm window, if there is one. Use your pry bar and a putty knife to carefully remove any molding or other material around the window. Be sure to wear protective gloves to avoid injury.

Next, unscrew the window from the frame, being mindful of any screws or nails that may still be attached. Once the window is loose, carefully lift it out of the frame and set it aside. Remember, old windows can be heavy, so having someone help you with this step might be a good idea.

Step 2: Prepare the Frame

Once the old window is out, you need to prepare the frame for the new window. First, thoroughly clean the frame and the area around it. This includes removing any old caulk, paint, or other debris that could interfere with the installation of the new window. Use your putty knife and a wire brush for this task.

You Need to Prepare the Frame

Once cleaned, check the frame for any damage or rot if you find any, repair or replace the damaged parts before proceeding. Finally, use your level to ensure the window frame is level and square. Adjust the frame if necessary and secure it in place. This step is critical as an unlevel or unsquare frame can lead to problems with the installation and function of your new window.

Step 3: Dry Fit the New Window

After preparing the frame, it’s time to dry-fit the new window. This means placing the new window in the frame without securing it to check if it fits appropriately. Lift the window into place and center it within the frame.

If the window doesn’t work, you may need to adjust the opening size or the window itself. Ensure the window sits level in the frame – you can use shims to adjust if necessary. Once the window fits appropriately, mark the places where you’ll drill holes for the screws.

Step 4: Secure the Window

Now that you’ve marked the places for the screws remove the window and drill pilot holes in the marked spots. After that, lift the window back into the frame, aligning it with the pilot holes. Using your drill, secure the window in place with screws.

Remember not to over-tighten the screws, as it can warp the frame. Double-check that the window is still level and make adjustments if necessary. Once the window is securely fastened and leveled, you can proceed to the next step.

Step 5: Insulate and Seal the Window

After securing the new window, it’s time to insulate and seal it. Start by inspecting the gap between the window frame and the window itself. If there are any significant gaps, fill them with expandable foam insulation. Be sure to use the low-expansion type to avoid distorting the window frame.

After the foam has dried, trim any excess with a utility knife. Next, apply a bead of exterior grade caulk around the edge of the window frame to create a watertight seal. Use your finger or a caulk smoothing tool to smooth the caulk for a clean, finished look.

Step 6: Add the Trim

Once the window installation is complete, the next step in the process is to add the trim. This gives your new window a polished, finished look and helps seal the window further. Measure and cut the trim to fit around your window, remembering to take into account the dimensions of both the interior and exterior sides.

The Process is to Add the Trim

To attach the trim, use finishing nails or a nail gun, being careful not to damage the trim in the process. Once the trim is securely fastened, apply a bead of caulk around the edges to seal any gaps and create a more professional finish. Remember to smooth out the caulk with your finger or a caulk smoothing tool. Finally, paint or stain the trim to match your interior decor.

Step 7: Cleanup and Disposal

After completing all the installation steps and finishing touches, it’s time to clean up your workspace. Make sure to safely dispose of the old window and any debris generated during installation. Consider taking any recyclable components, such as aluminum or glass, to a recycling center.

Sweep the area to remove any small debris, and wipe down your new window to remove any fingerprints or smudges. Lastly, store any unused materials properly for future use. After completing this step, you’ve successfully replaced your aluminum window.

Step 8: Conduct a Final Inspection

After cleaning up, take a moment to conduct a final inspection of your newly installed window. Check the function of the window by opening and closing it several times to ensure smooth operation. Inspect the seal around the window one last time, looking for gaps that may need additional caulk.

Check the interior and exterior trim for imperfections and touch up with paint if necessary. Lastly, look through the window from various angles to check for any distortions in the glass. A thorough final inspection is crucial as it allows you to correct any minor issues promptly, ensuring that your new aluminum window serves you well for years to come.

By following these steps, you can easily replace an aluminum window.
