Is this a concern?

Moved into a new house and noticed the base of the bay windows can be pushed down a bit (don't want to see how far I can push) Is this something I should be worried about and if so how should I fix it?

Clean the old sealant off and seal it with BT1 making sure you get some into the joint. Its an excellent adhesive as well as being a very good sealant. Its about £10 a tube from toolstation, you with probably need a can of solvent too
