I have flagstone coping and the grout is cracking. Also the material that was used to fill the gap between the coping and decking needs to be redone. There are also hairline cracks along side some of my waterline tile. Are these things I can easily repair or do I need to find a professional. If it is a DIY project can anyone suggest products I should use.

If you have little or no experience with masonry (tile, cement, etc), I suggest you let a pro do it. It sounds like some of the coping may have to be removed and reset. That's a lot of heavy lifting and grinding.
