We purchased a designer Pella sliding door from Lowes and had one of their installers install the door. First, the day they were suppose to install never happened. Received call at the end of day to reschedule another day. After installer installed the door, asked me to sign that the door was installed and never asked me to check the door and sign off. Without thinking of any consequences, I signed. After we signed, we noticed that there was a slight dent in the door and 2 scratches on the paint. Even the threshold had a dent. Called Lowes and complained and they told us that they will do nothing because we signed off on the paperwork. A large company like Lowes, should try to satisfy customers. This was a very expensive door! It is all about the money – greedy! Will never purchase from Lowes again. Do not recommend.
