As a general rule, you will not be able to get a crack front window repair if it is more than 6 inches long. If your problem is a chip instead of a crack, the chip should not be larger than a quarter. Keep in mind that these rules are not hard and fast, always check with a local professional.
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.
Tarsis recovered his wits and stealthily made his way around the merchant's room, relieving the discarded clothing of a weighty purse and other valuables. Turning to a chest of drawers, he found and pocketed several rings and a golden necklace. Not wanting to chance his luck too far he made his way to the door and after a brief windshield repair glance along the corridor he retreated the way he had come.
Check with your insurance, because it's likely your insurance will pay for some forms of windshield chip repair. They may even waive the deductible, since repairing your windshield is so much cheaper than replacing a windshield. Should you need total windshield replacement, you may have to pay a deductible with your insurance.
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.
Repairing a windshield has several benefits opposed to complete replacement. Repair is always going to be less expensive. Repairing a chip or crack also doesn't damage the watertight seal created in the factory windshield, replacing the windshield will require this seal to be broken. Secondary windshields tend to leak over time. Repairing a windshield is also much better for the environment since your windshield won't end up in a landfill somewhere.
