Install Exterior Window Yourself

Marvin Window Installation

Replacing your windows is a great way to make your home more energy efficient, and can help you save money by lowering your heating and cooling bills. Replacing your own windows is not as difficult as you might think, and GNH can help you with your Marvin window installation.

Once you have removed your old windows and are ready to install your new windows, you can make things easier by first removing the new window panes from the frame so that it is easier to move the frame around. To get your frame in the opening, gently tilt it in place. Once it is in, make sure the frame is level and that all the sides are plumb and lined up correctly. You can now add the panes back in as this will help square up the frame. After they are in, check along the bottom to make sure the reveal is the same. Using long 10- or 12-penny finish nails, nail in at least 3 nails per side. However, check the specifications from the manufacturer first just to be sure.

Finally, pack insulation along the sides, bottom, and top of the window, and finish the outside of the window with flashing to stop air infiltration.

Remember, if you have any questions about installations, just call our specialists at GNH Lumber.
