Hi 'LucyS',

Light seals are often a DIY fix that is not terribly difficult if you are handy with small tools - and are so inclined to give it a go. It's one repair that's often worth a try, since if it doesn't work out one can always fall back to having it redone professionally.

One possible online source for the required foam is Micro-Tools.
