What should I do if the developer has agreed to make the necessary repairs?

If the developer is agreeing to do the repairs, that’s great news. What you have to make sure, however, is that the repairs the developer is doing are the appropriate repairs so that the component that they’re repairing lasts as long as it should. In other words, you don’t want somebody going out with a tube of caulk and some paint and saying the problem is solved. The way you do that is that you hire an engineer, typically through a construction defect attorney, who can investigate, determine what the proper method of repair, and then make sure that that’s what it is the builder is in fact doing.
