They seemed very knowledgeable of elevators on the phone but when he came he seemed lost. He said it was an "easy fix" just need a new battery. It took hours & when the battery did not work he charged us $725 & gave us a proposal of $3800 for a new control panel, that they could not guarantee would work. We called FL Lift, they had it fixed in less than an hr & told us Core could not fix it because they are not an authorized dealer for our type of elevator & do not have the correct tools, it cost us $550 to fix.Guess Core wanted to take us for a ride & they did for $725. We will be staying w/FL Lifts. read more
