There is no problem just replacing only the brick and tile that you are having a problem with. Just an observation and not a scientific study but I have noticed more coping problems with pools that have a solid cover that covers the coping in freeze thaw areas. Hope this helps

imfignewton,

Right now, the caulking that we put into the expansion joint between the deck and the coping is still there, so we can't really look down into the expansion joint to check of the deck is touching the beam.

Can you clarify what you meant when you said "There is no problem just replacing only the brick and tile that you are having a problem with."?

Did you mean we should be ok just replacing the tiles that fell out and re-doing the caulking in the expansion joint?

Or, did you mean that it should be ok, to re-cope and re-tile the entire pool but not do anything with the deck?

Thanks,
Jim
