Can't repair them.
Broken windows and doors should be replaced. This generally does not include broken window seals unless it affects the marketability of the property. FHA now permits an “as-is” appraisal for homes being financed with FHA loans that have minor property deficiencies resulting from deferred maintenance and normal wear and tear. In fact, Mortgagee Letter 05-48 states the FHA provides that one example of minor property conditions that do not require automatic repair for existing properties as being cracked window glass. Thus, I doubt a broken seal would be required.
