We purchased top of the line hardwood flooring from Expo. Three months after they installed it, floor boards started to curve upwards. The installer claimed it was our fault and asked us to repair adjacent patio to solve problem. We did as asked, had the installer back to replace curved boards. Same problem happens immediately. We contact Customer Care of Home Depot who ordered an independent inspection of flooring which showed that the installation was faulty, resulting in the curving of the floorboards. Instead of immediately making good, Expo begged us to have another inspection since their installer had appealed the inspector's finding and was giving them trouble about compensation. We (stupidly) agreed. The second inspector skipped many of the tests the first performed and decided that the entire fault was ours, not the installers. Home Depot has offered us a 20% discount on the purchase of another floor for our room. The findings of the first inspector have been completely dismissed, and Home Depot Customer Care is not returning our calls asking for an appeal or a further consideration of the 1st inspector's findings. This seems to be when a large corporation (correctly) assumes that they have lawyers, and we don't. Now we have to badger or threaten or who knows what? In the beginning of this process, I asked for "fairness", and I have not received a drop of fairness. Be careful of Home Depot and Expo.
