USGlass found the competition to be pretty tight when it came to the cost of replacing the glass in sliding doors in Wilmington, Del.; Des Moines, Iowa; and Sacramento, Calif. 

We asked about clear, tempered, insulating glass units measuring 34 by 76 inches and 5⁄8-inch think. 

The range wasn’t too great—most estimates were within $80 of each other—until we hit the West Coast. Coincidentally, the company that stands out was the one that warned us that “patio door glass can be more expensive since it’s safety tempered.” Perhaps it’s not as expensive as they would have us think. See how your prices compare to these averages from across the country.
