I had a bad leak in my front windshield on my 40" Itasca Meridian (2010) and Glass Commander came out and cleaned up the entire area of the leak and then some. They resealed the entire area and that night we had a downpour (for the desert in AZ) and the next morning there was no water in the RV. I can only say good things about the entire experience and will recommend them to anyone who asks. They were professional and friendly and got the job done in a very reasonable amount of time for a reasonable price.
