This is our 20x40 Vinyl IG Pool built in March 2003. As you can see, it is bordered by red bricks. We did not install this pool, and have no contact with the construction company who did, so I am looking here for help. There is a small gap in between the actual concrete pads around the pool and the red bricks. In most parts it is filled with a concrete like substance, but in others there is something that looks like silicone caulking. The silicone parts are starting to lift and pull out, and the concrete like parts are breaking up and falling out. Any suggestions on who to hire to fix this or if it is even a DIY project? The bricks are also falling apart in places, so I am also wondering who to hire to fix those. Any suggestions would be appreciated! I am new to the pool business, we just purchased this house two years ago, and I am wondering if this is normal wear or whether they should have lasted longer.
