Sagging Hinges
A sliding front door can be a snore and could affect the stability of your home. Fortunately, most of the time, it's easy to fix. If your door starts to slide, it's imperative to fix the issue as soon as you notice it. If not, small problems could turn into more serious issues like squeaks, or other major misalignments.
Begin by inspecting the hinges to determine the root of the issue. The loose screws are often the reason. If tightening the screws doesn't resolve the sagging replacement of them with longer screws could aid. Longer screws can help support the door's weight and prevent it from sagging over time.
You may also have to install shims to adjust the hinge's position. Thin strips of material can be inserted between the hinge and the jamb or frame, distributing the weight of the door evenly and preventing future sagging. Use a door stopper or ask someone to hold it in place while you remove screws from the hinge. Then, carefully lift the doors off the hinges.
It is important to recognize that a sagging door can sometimes be caused by uneven floor level. This could lead you to examine the floor for any problems and correct them, which will allow you to solve the sagging problem without focussing on the door itself. In some instances the sagging might be due to the condition of hinge components, like the knuckle or pin. In this case, you will need to replace your hinges. This is a difficult task for those who do not have carpentry experience. In certain cases the hinges that are sagging may suggest that the door's frame is too heavy for the frame or jamb.
Doors that aren't aligned

Another common cause of misalignment is the presence of moisture in the air. This could cause the wood to expand and cause your doors not to shut properly. However, this isn't an issue that lasts long and typically clears up as the humidity decreases.
Many people notice that their doors aren't aligned after a rainstorm, but the solution is simple: simply tighten the hinge screws to correct the alignment. This will usually solve the problem, but if it doesn't you should consider using a longer screw for your hinges. This will give them more strength and prevent the hinges from loosing again in the near future.
Another issue that could be a problem is an unaligned strike plate. Typically, the strike plate will need to be moved lower to allow for more space for the latch. replacing glass in french door is also an easy solution, but you'll have to remove the current strike plate and drill new holes for it. Use a wood dowel with the same diameter as the screwhole to fill the old hole and then secure it in its new location.
Broken Latch

If the latch does not retract when you manually push it or turn the handle, it is likely that the internal mechanism has broken. You can identify the cause of the issue by examining where the latch contacts are located. A lipstick test can help identify if the problem is caused by sagging hinges misaligned latch bolt, narrow strike plate hole or a combination of issues. To perform the lipstick test put a strip of lipstick (or similar marking material) on the latch. Close and then open the door. If the latch is in contact with the lipstick beneath or above the strike plate's hole, it indicates that there is no contact between the latch and strike plate.
The best method to fix this is to lubricate the latch. Lubricating can be done with graphite pens, which works better than WD-40 or other dry oil lubricants. You can also try inserting a cotton swab in the keyhole to get rid of any dirt that has accumulated in the keyhole.
If lubricating the latch doesn't solve the issue, it might be necessary to reposition the strike plate. If you've sanded, shimmied or pushed the hinges or widened the strike plate hole, you'll need to move the strike plate to the proper position in relation to the latch. Test the lock after having adjusted the latch and moved the strikeplate to the proper position. If your latch remains stuck you can employ a wood filler fill any old screw holes or gaps that were caused by moving the strike plate or sanding the hinges. Then, you can stain or paint your frame to complete the repair.
