How to Repair an Aluminum Window Frame

An aluminum window frame is something that will allow you to have protection from hot weather as well as from cold weather. You will find that these windows are easy to take care of and will last you for a long time. However, it is common that you may need to do a little bit of repair work here and there.

Step 1 – Remove Screens and Windows

Annually, it is a good idea for you to take the screens out. Lay them down on a flat surface so that you can clean them off with a soft bristle brush. Also use this time to examine the frame and make sure that it is in good working condition. Clean it as well with your brush. Before putting the screens back up, spray them down with a garden hose. The windows will need to be removed less frequently for cleaning. Still use this time to check out the frame to make sure it is still holding up.

Step 2 – Vent Holes

Between the exterior windowsill and the bottom of your aluminum frame, there will be small vent holes that you will need to examine from time to time. Make sure that that these holes are opened up so that any moisture filled air will be able to escape. It will also allow for proper drainage and prevent your frame from getting water damage. If the holes are clogged in any way, use an awl to open them up.

Step 3 – Sash Slide

You will also need to get your sash removed and also clean up the channels using a stiff bristle brush. Make sure that the sash frames are cleaned with steel wool that is number 0000. Get the sides of the sash wiped up with a cleaning cloth that is sprayed down with a silicone lubricant. Do this before reinstalling.

Step 4 – Broken Glazing

If there is any broken glazing that is on your sash, then it is important to remove it as soon as possible so that it cannot do any damage to your frame or your window. In order to do this, you will need to get your screen sash completely removed. From there, you will need to remove the glazing. If there are any metal keys that are inside of your frame that keep the corners secure, then you will need to remove the screws. If your corners happen to be crimped then get your awl back out and take the vinyl spines out.

Step 5 – Install New Glazing

Once you have removed the glazing, you are ready to install the new glazing. You will need to make sure that it is about 2 mm smaller than the inside frame. This will allow it to expand. Lay your glazing vinyl onto your glass and press it directly into the frame. Get your corners assembled last.
