We have to replace carpet & padding in a walk-down room because we had ground water come in to the house. The stairs and landing were perfectly dry. When the carpet people gave an estimate they said they could not match the existing carpet and we needed to replace the stairs carpet also. They gave the estimate to also replace the padding on the stairs as well as the main room. Do I really need to have new padding put in the stairs. The padding is 8 yrs. old. Are they just trying to get as much money out of me that they can? Thank you
