Field glazed windows are simply a piece of glass set in an opening frame on site and sealed with caulking and trim. It is our experience that field glazed windows more often than not leak. Replacement windows have frequently been installed without proper flashing resulting in leaks that may not be detected until severe damage occurs. If the siding around new windows appears to be have been undisturbed, it is usually an indication that the replacement windows have not been properly flashed.
