Bifold Door Seal Repair Bifold doors make a fantastic feature for any home, but they require regular maintenance and proper installation for proper operation. This includes a thorough integrity inspection along with lubrication and a detailed report of any problems to prevent them from happening in the future. Bifold doors are designed to be slightly smaller than their frames in order to prevent sticking. This also means air can get in through the gaps. To stop this from happening, install a weather seal.
