If the dishwasher you purchased from Home Depot cost $396.00 or more they will install the dishwasher for $99.00 and they will deliver the dishwasher to your home for free.
If the dishwasher cost less than $396.00 then there's a $59.00 delivery fee plus the $99.00 dishwasher installation fee.
Home Depot will send out a contractor who will do the installation for you and they will schedule the installation and should have the dishwasher installed within 2 to 3 days after purchase.
When I had Home Depot deliver and install the dishwasher in my home it took 3 days for the delivery and installation but I wasn't in a hurry.
They did a great job at installing the dishwasher.
