How to Install Replacement Windows

Windows are one of the major and important components of a home or any enclosed structure for that matter. In a home, they can contribute to the energy efficiency as well as to the beauty of the interior space. Once damaged, though, they need to be replaced with a new one as much as possible to keep the entire home in tip top shape.

But this problem can be easily solved today using the replacement windows. These are of three different types – sash, insert and full frame. The sash type provides the old window frame new sash and jamb liner while the insert replacement window also known as a pocket window involves a secondary frame that can just be inserted into the existing opening and secured to the side jambs. The full frame type has a complete frame and needs to be installed to the rough framing of the old window.

First determine the style and material for your new windows. Then measure the height and width (jamb to jamb and sill to top) from the sides and center before you order your replacement windows.

If your existing frame is already rotten, make sure to get rid of this. Take off the sashes, old caulk and nails. Take out the parting beads as well to get the upper sash.

You can also remove the inside wooden stops of the old window but you can still use them on the new one. While you do this, retain the interior and exterior casings.

Clean the jambs by taking off loose paint and covering cracks and holes using wood putty. Smoothen them afterwards using sand paper before priming and painting the surfaces.

At this stage, it may be ideal to remove the sash weights from their pockets and provide insulation to the window frame. You can just unscrew the side panel which covers the pockets.

For the insulation, polyurethane foam is considered by experts as more effective than fiberglass. Use keep in mind to use low pressure when spraying the foam into the holes. Allow them to harden for at least six hours.

Once you have your replacement window ready, test it into the window opening to see if it fits well. Next step is to apply caulk on the inside edge of the window stops in the outer portion and also on the windowsill.

Now it’s time to put back the window in the opening making sure that you center it into the frame. Check that it is also level and square. Make sure to press the window tight against the exterior casings. Shim if necessary to make a perfect fit.

The inside stops will have to reinstalled next using finishing nails 1 ½ inches in size. The area where the stops meet the window frame should then be applied with caulk.

Finally using a two-inch screw, drive it loosely through the upper side jamb and into the frame. The reason for loosening the screw is to make the window function well.

Test the window by opening, closing and locking it. When it’s okay with you, secure it in place using the predrilled holes and the screws.
