These are often put in place by nails and then covered with paint, so you'll likely need to use a knife to cut them off. Once the pockets are gone, you can begin to chisel away any wood that is rotting, and then apply a high-quality water-resistant wood filler. Once the wood filler has dried the primer coat must be applied to prevent further decay.

It is a smart idea to inspect inside the window the sashweights to ensure they are in balance. They should not be in the wrong alignment or pulled one side harder than the other.
