I'm trying to decide whether to redo a gypcrete floor underlayment completely or just repair what I can and go with it. We have a third floor condo that flooded, the living room floor now sags about two inches to the center. It was inspected and is structurally ok. The gypcrete that is currently laid down is intact but softer than it should be. To contract a company to come repour the entire floor, they want $5350. Or I could cut out the areas that are sagging the most and fill in the worst areas myself and have a mostly level floor. Aside from the fact that it's soft, I was thinking of leveling it myself but since it's so soft I'm waffling between saving money and having it completely redone.
