We had a new quartz top installed a couple of days ago. Full payment was issued. While I was doing some plumbing under the sink I noticed both corners where the top meets the sink were cracked off and glued back on. This was never disclosed and not sure if it happened pre or post delivery.

I’m curious why a similar fracture occurred on both sides. Is this common? Should we make a big deal about it?
