Tips on How to Replace Fitted Windows

Remove the Trim

The first step in replacing an old aperture is to remove its jamb extension and trim with the use of a prybar. The jamb extension is a small piece of wood previously ripped down and fixed in the aperture jamb to create an even spread with the wall.

When you have done this, observe the extension from different angles to know if they are even. You can also adjust them accordingly if you find a deficient edge.

Remove the Old Window

To remove the old unit from the jamb, you have to unscrew it with a screwdriver. Afterwards, carefully pull it so you do not break the glass in the course of removal. Take note too that most windows come with sashes and moving tracks that are usually found on the side. These kinds are easier to remove when you pull one sash at a time.

Prepare and Repair the New Aperture Opening

When you are through with the removal, examine the condition of the jamb to find out if there is any damage. It is usually common for an old aperture to leak and rot out the jamb. In the event that there is some damage, it will be apt to repair or replace the damaged areas before you proceed.

Additionally, you have to measure the craggy opening to ascertain if it can accommodate your new aperture. The measurement for this opening is 1/4” to 3/8” and this should be bigger than the outer dimensions of the new unit.

Replace the Stop

Every window has a stop which is a small piece of wood cut and placed on the outer part of its jamb. The stop prevents the aperture from any form of sliding that moves past its opening. If you have to replace your aperture, check the stop as it is most likely that it is disfigured, and you will have to replace it before installing a new one.

Install the New Window

The installation of the new window is not a difficult task. You will have to run silicone through the interior of your aperture stop and slide it into place when you are sure the silicone is fitted nicely. Place the level at the edge of the aperture and use cedar shims to hold the jamb and the base of the frame to get a level sitting.
