There is a small gap top right of the left opening of my upvc window unit . It looks as though it needs a little lift or adjustment from the bottom left. Window shuts fine can just see a bit of daylight. At a loss as what to do and need advice. Thanks for any help given.

if it is on the opening side you need to remove the glass and re pack it to lift the offending corner up. pack from the hinge side at the bottom and the opening side on the top. if it is on the hinge side then you'll probably need to change hinges
