We installed an Easy-Vent storm door last fall and it must have blown open over the weekend. Now it no longer closes (won't fit in the frame). There are two closers/pistons on the door and I think the bottom one is blown and therefore no longer creating the tension needed to keep the door tight in the frame. Is it possible to repair the closers or do you need new ones? Anything else I can check that might be causing it to not fit the frame anymore? Of course wind damage isn't covered in the warranty!
