Noticed today my Gardiners SLX 25 the top section seemed a bit dodgy.  I fully extended it until it came out of the pole and the bottom 1-2 inches has a crack in it.  Too be fair ive had this pole for over 2 years and it gets bashed around alot.  the red tape to signal where to extend to has been completely worn off for a few months now, so probably been over extending the pole and its cracked.  
So is there any fix for this, or do i just need to get a replacement section ordered?
First time happening for me so wondered what to do.  Second section is also looking a bit dodgy so may get that replaced aswell.  It's the top 2 sections that obviously get used the most in standard domestic window cleaning.
