Home Depot backsplash estimate. Was told by the company to call Home Depot to confirm they have the materials before they can schedule the appointment (isn't that their job?). Called and confirmed inventory. Called them back and they said they can't schedule the install until they receive and review the "materials." No response for a number of days. Suddenly received a call days later that they would install the backsplash on the day I requested but I am responsible for any damage they cause to the wall... hmmm... and that the damage is very likely and that I have to hire another contractor to do the work. I know how to install these and explained they charged me for wonder board and they could just rip out the drywall... they seemed to have no idea what I was talking about. Decided to let them do the install anyway... suddenly, i receive a call from a "delivery" person from JW to drop off the materials. They drop off DAMAGED materials that I had to send back and exchange. BTW, that means that there was no "review" of materials that they described because the driver from JW said he just picked them up from Home Depot and needs to drop them off with me. With the hassle of discussing the install and damage to dry wall, which they didn't seem to fully understand... and the damaged materials and the poor customer service and follow up... I would not recommend this company. I cancelled my service with them and installed the marble backsplash myself. Home Depot needs to find someone else for their installs.
