Tile - used 2 different color grouts, cracked tiles, tiles uneven - overcut the interior door trim/jambs. didn not complete the grouting, grout on walls and on interior stone work (in the pours of the stone - 3 inchs high)

Hardwood - Different wood thresholds between hardwood and carpet - gaps in the joints of hardwood where a quarter will fit and you can see staples - hardwood does not meet the tile evenly - overcut all interior door jambs and trimwork -

Just to name a few

Attempted to have problems fixed - Warehouse carpet wanted to take some money off bill to go away - Ended up getting sued by warehouse carpet for non-payment -

Lawyers took it over the top and matched the bill with what I owed - So in turn lost double
Would not use Warehouse carpet for anything!!!
