Hi,
I know my chimney needs repair, but every time the chimney sweep guys come to clean the flue, they tell me something different (I need "Chimney Saver" coating, or I need a "Crown Seal" or something costing $300+ labor) and I fear being scammed.
Can you take a look at these photos? All opinions welcome.

I'm not beyond a DIY project, but it's kind of high and not too comfortable on ladder for extended duration.

Thanks!
