They can be nailed in place and stuck with paint, so you'll likely need to use a knife to get them off. After the pockets have been removed, you can start slicing out any wood decay and apply an excellent water-resistant filler. Once the filler is dry, it is recommended that a coat of primer be applied to guard against further decay.
It is a good idea to examine inside the window the weights of the sash to ensure that they are balanced. They shouldn't be misaligned or pulled one side more strongly than the other.
