A properly puttied window glass will keep the weather out and the heat or air conditioning in where you want it. Buyers will appreciate the care you took to maintain your windows.
House Selling Tips – Texas House Buyers: Replacing your windows with new vinyl ones is a good return on your investment when you plan to sell your house. If you can’t replace the windows, you can at least make some improvements that will help keep the heat in for winter and the heat out in summer. Buyers will be looking for anything you can tell them about how you have made these energy saving improvements in the house.
First, look at the glazing. It’s the putty like stuff around the window that holds it into the frame. Old windows have typically dried up and cracked glazing. If it’s dried up and cracking or missing in places, get some $5 glazing putty, a few glazing points for about $2 in boxes of 100, and a putty knife. Remove the old glazing with the putty knife. If it doesn’t readily come out, try heating it gently with a blow dryer or heat gun. Don’t get it too hot or let the heat stay on one spot too long or the glass could crack there.

Remove the old glazing points. You can now take the window out of the frame. Put it in a place where it won’t be broken. Sand the sash where the glass fits in and apply a little silicone in the track to hold it in place. The new glazier’s points will be inserted next. Using your putty knife, push the points into place along the glass edges. This step should be done slowly and cautiously to be sure you don’t break your glass.
The putty comes in a tube or in a can, depending on how much or which type you buy. The tube is sometimes easier as you’ll cut the angle at 45 degrees to create a tip. Go along one side of the glass with a thin bead of putty. If you use a can of putty, take some out and make a long, thin wormlike string that you’ll lay into the corner of the edge of the glass.
Using the putty knife, make a 45 degree angle by smoothing the putty along the edge. Look at a finished window or one of the old ones for an example. The putty shaped in this way will send any moisture away from the channel the glass fits into to keep it dry. Clean the windows thoroughly and make them sparkle before you show the house.
