Andy and Crystal (owners and installers) were a pleasure to work with. After a number of break-ins in our neighborhood where the bad guys came through the patio door, we asked for recommendations from our neighbors. They all recommended we put in the security film on the patio door. Everyone in our neighborhood have used Mensch's. We were not disappointed. We called and Andy answered the phone. They visited our house that day for an estimate. The presentation was professional and they answered all of our questions, giving us several options and leaving samples. Two days later, they installed the film. We were impressed they took their shoes off before entering the house without being asked. It was obvious they knew what they were doing, as they went straight to work. In no time, we had security film installed on our patio door and one of our windows. Before leaving, they gave us instructions on how to care for the film and the lifetime warranty. We recommend them highly. We are going to take their card to our next Neighborhood Watch meeting. These are good folks
