I don't even know how that many bricks ended up in the pool. Seems like sloppy work, and if it was the workers that dropped bricks in the pool, shouldn't they be the ones to clean that up?
Also, why didn't they drain the pool before work started? Wouldn't it have been a good time to take advantage and resurface the pool during this renovation? He mentioned something about replacing the pool lighting to led, can they do that with a full pool? And, why would they put the pavers around the pool, but not the expanded area? Shouldn't they have cleared out and leveled the entire area to be paved and do it all at once?
And the house should definitely have been painted right after the cage was removed and before the other work started. I assume they weren't planning on repainting until they saw that nasty mold stain.
