Johnston Paint and Decorating

We contacted the seller of our home to find out who had provided our carpeting and tile because we were having ridges popping up in most of the rooms of our home, upstairs and down. The seller provided the receipt, so we contacted Johnston Paint and Decorating, where the receipt originated. We have been in our home just under three years. We did notice a few ridges in the carpet about three months after moving in. They got increasingly worse and more numerous as time went on. I called Johnston Paint and Decorating to ask if they could help us out with this, basically if they would stand behind their product. I was told that they would not, that I should have called right away when we first noticed the ridges. I really think this is unreasonable because three years ago we had just made a major move, gotten unpacked and settled. I can't imagine packing every thing up and moving all the furniture out to have it restretched three months after moving in. I had previously called another company about having the carpet restretched. The person on the phone said that had they been the original installer they would have stood behind it because they gave a !00% guarantee. That's what gave me the idea to find out who had originally installed our carpet to see if they had a similar policy. Update several months later: Since writing the above we had a leak from the toilet in the master bath. A contractor other than Johnston Paint was called and they replaced a ring under the toilet. They told us that it was not a professional job whoever installed the flooring under the toilet. They said it was standard practice to put concrete board under toilets, which had not been done. They were sure that this caused the toilet to leak because the structure of the floor was not solid enough. They also said they had never seen a type of screw that held the toilet down onto the floor used before. We now need repair on the ceiling below the toilet also, as the leak was slow and caused mold buildup and softening in the shower ceiling below. Additionally, there is a crack in the tile near the toilet that the improper subflooring caused when weight on the toilet occurred in normal use. Another tile in the foyer was loose and not sealed properly, something we discovered after moving in. The receipt we have shows that Johnston Paint and Decorating did the tile job. They apparently used subcontractors who did a lousy job that possibly saved the sellers some money, but caused us lots of money and headaches after the sale. I do not plan on doing business with Johnston Paint and Decorating in the future. I will go with a company that stands behind their product and workmanship.
