Even if you do have to get the entire windshield replaced, you could still get off the hook if your insurance company will cover it. Free chip front window repair is included in a lot of policies, so check this out. Just remember that insurance providers often have stipulations about which glass company you are allowed to go with, and therefore you will probably have to use a company they suggest.
You will next see what is called a parting bead which is a small trim piece about 1/2 inch by 3/4 inch in size partially buried in the window casing. It separates the two sashes. I recommend replacing these and you will find they are very difficult to remove without splintering them. If you are repairing the window and not installing new side tracks you must replace the parting beads. The upper sash and weight removal is the same as the bottom. Don't forget to open the sash pockets at the bottom of the upper sash tracks as well to allow sash weight removals. With sash, weights, nails and pulleys removed, clean all loose paint from remaining surfaces and if your sure it is not lead paint, some sanding may be in order as well.
Allow some time of about half an hour for the windshield repair spot to dry properly under the sunlight. Then the air bubbles should be checked. If there is any sign of them, more compounds should be placed into the spot.
Unfortunately, not all windshield chips are created equal. There are four main types of chips: star break, combo break, partial bullseye, and bullseye. Each one may spread differently or at different speeds, so it's important to take your car to an expert as soon as possible to determine if you can have windshield chip repair done.
Another way to figure out ARV is to get an appraisal from a certified appraiser. Yes this costs money, but if everything else looks good about the deal and you are uncomfortable with the realtor's comps, you can always get the opinion of another professional. They go more in-depth when appraising properties then realtors might. However I only trust the appraisal when I actually hired the appraiser. This way I know that I have given him/her the instructions on how I want the appraisal to be completed.
After removing the film, use a hard object that won't scratch the glass to remove excess resin. Something like a plastic scraper or piece of wood, such as a popsicle stick should do the trick.
