I've 3 slide glass 72x84 sliding doors need to replace. How much it cost per door include labor? Please give me a quote. Thank you.

Uh....probably calling Home Depot themselves might help you to get a better estimate...

Depending on what brand you are looking for regarding the glass doors you might be looking into 150 and up per door. The Home Depot doesn't do labor, you would need to look for someone on your own.
