How to Install Replacement Double Hung Windows
Installing replacement double hung windows can be a rewarding DIY project that can enhance the energy efficiency and aesthetic appeal of your home. Double hung windows are popular for their ability to open both the top and bottom sashes, allowing for better ventilation and easy cleaning. If you’re considering replacing your old windows, here’s a step-by-step guide to help you through the process.
Step 1: Gather the Necessary Tools and Materials
Before you begin, gather all the necessary tools and materials. You’ll need a saw, screwdriver, drill, hammer, utility knife, measuring tape, level, caulk gun, shims, weather stripping, and the new double hung windows. Make sure you have all the required parts, including the window frame, sashes, balances, and hardware.
Step 2: Remove the Old Windows
Start by removing the old windows. First, take out the interior stoppers and remove the sashes. Next, remove the exterior stoppers and the window frame. Be sure to take out all the nails and screws, and set them aside for later use. If the old windows are painted or sealed, you may need to cut through the caulk and paint with a utility knife.
Step 3: Clean and Measure the Opening
Once the old windows are removed, clean the opening to ensure a smooth installation. Measure the width and height of the opening to ensure the new windows will fit properly. Double-check the measurements and compare them to the size of the new windows.
Step 4: Install the New Window Frame
Position the new window frame in the opening, ensuring it’s level. Use shims to make any necessary adjustments. Once the frame is level, nail or screw it into place. Be sure to check the frame’s alignment with a level to ensure it’s perfectly horizontal and vertical.
Step 5: Install the Sashes
Next, install the top and bottom sashes. Place the top sash in the frame and secure it with the appropriate hardware. Then, install the bottom sash and secure it as well. Make sure both sashes are aligned and move smoothly when opened and closed.
Step 6: Caulk and Seal the Window
Apply caulk around the perimeter of the window frame to seal it against the exterior wall. Use a caulk gun to apply a bead of caulk, and then smooth it out with a damp finger. Additionally, install weather stripping around the sashes to improve energy efficiency and reduce noise.
Step 7: Test the Window
After installing the new double hung windows, test them to ensure they open and close smoothly. Check for any gaps or air leaks and make adjustments as needed. Once you’re satisfied with the installation, you can reinstall the interior stoppers and enjoy your new windows.
Conclusion
Installing replacement double hung windows can be a challenging task, but with the right tools and a bit of patience, you can successfully complete the project. By following these steps, you’ll be able to enhance your home’s energy efficiency and enjoy the benefits of new, functional windows. Remember to take your time and double-check your work to ensure a successful installation.
