Hello. Our in group pool is only 3 years old but it appears due to settling, we have cracking happening on the cool decking AND in the "grout" line going around the pool between the decking and the coping. We also are experiencing some mildew "rot" on the "foam lining" next to our house slab/wall and the decking shown in the attached pictures. I have reached out to our pool builder but no response and I am getting quoted around $1k to fix these issues from a separate pool company (which he also said this mildew rot is something he hasn't seen before)...any thoughts or feedback appreciated!!
