It may be possible to repair your door, but if it’s taken too much of a beating, the best solution may be a replacement. A properly installed, good quality high-speed cold storage door will help regulate the temperature, keep out vermin and moisture and help keep your frozen goods frozen.

Here are some of the types of freezer doors to consider as a replacement.
Manual single swing doors – Used for personnel and hand truck traffic; designed for interior or exterior use where environmental control is desirable.
Horizontal manual slide doors – For traffic handling goods and materials, and for personnel. This is a good option if there’s no space for swing doors; for large doors, these provide a good seal. For nterior or exterior use.
Traffic swing door – Self closing, these are double doors that allow two-way traffic in either direction for greater efficiency; they may also be impact traffic doors that open in either direction. For freezer use, they will offer thick insulation in the form of a full perimeter, front-to-back thermal break, and dual perimeter gaskets so there are no hard-to-seal hinges or cutouts.
Vertical lift door – A good solution for areas that have several openings in close proximity, or where there’s minimal room at the sides, such as loading docks. For interior or exterior use. Sectional overhead doors are another option for these conditions.
Push-pull gear-drive door – Designed to prevent cold air loss, some models come with an air curtain heating system to prevent condensation and frost. Interior use.
It’s always recommended to install strip curtains to freezer doors. Made of PVC, the strips reduce air loss and help to regulate the freezer temperature.
