How to Replace a Broken Anderson Window


I recently had one of my many Anderson windows break for no apparent reason. It has two panes of glass and the inner glass broke one night. After duct taping the window to make sure the glass wouldn’t fall out, I called Anderson Windows and ordered a replacement. The upper window was part # 1620854. The woman I talked to said that they have almost all replacement windows for any windows manufactured in the last 30? years. My windows is twenty-two years old, so I should be ok for a while. The replacement window cost approximately $230. The cost does include shipping.

Here’s the link for the replacment window.

The new window comes with easy to understand instructions, but here are a few hints to make the job easier.

  • Get some help – this is a two person job.
  • One of the first things you have to do is remove the Lower Left Jamb liner. It’s easy to take out the screws. Then you need to take a knife and score the liner along the wall where you have probably painted. You need to break the paint seal first to get the liner to slide down.  I also spray the wood with silicone every chance I had. It really helps. Take your time you don’t want to break the liner. Also, make sure you have taken out ALL the screws.
  • The next part is hard and you want some help with this. When you SLOWLY remove the windows, you have to manually hold the sash cord. It is under EXTREME tension and is hard to hold with your bare hands. There is a small piece of plastic at the end of the sash cord.  I jammed a pair of needle nose pliers in the hole where the cord comes out and then also put in a small nail in the molding to tie the cord onto. The video suggests you can let the piece of plastic rest at the top of the window. For me, the opening seems to large and I was afraid it would go into the hole.
  • Here’s another way to hold the cord and plastic. Using a coat hanger, bend it into the shape of an S – with a large part for your finger and a small part to hook the plastic part as it comes out of the window. As you grab the plastic part, you can then slowly move the cord and plastic part up toward the top and then it will hold because of the coat hanger. Thanks to Tony C. for this tip.

  • SILICONE – before I re-installed liner I thoroughly siliconed the wood and liner and it went into place easily.
  • When you’re done you may want to silicone all the liners to make the windows easier to move up and down.

Take your time and you and a friend can do this job and save some money.
