Even if the damage is small, it will still likely not be a good candidate for repair. Most automotive side and vent glass is made of tempered glass which explodes when damaged.
There’s a great variation in the cost of side glass replacement, depending on whether it opens and closes or if it is stationery. Replacement of stationary glass will be less expensive.
You can expect to pay anywhere from $100-$900 for quarter glass window replacement. Depending on the year, make & model, the average quarter window replacement cost will be around $200.
