Could you please post some pictures farther away also, so we can get a perspective of the seams in relation to your entire counters. Also, was it specifically stated in your counter purchase and fabricator’s counter sign off papers, that your butlers pantry would have a seamless counter? I chose seamless counters for my quartz Silestone counters and this was specifically stated in our counter and the fabricators contract. I wanted seamless, as I read too many issues with counter seams in various Houzz posts. I also had the luxury to work from home when I had my kitchen and bathrooms renovated. My husband was retired, and we inspected all products prior to installation. My seasoned kitchen designer told us he uses only experienced counter fabricators who have extreme attention to detail. I had no issues with my counters. Hindsight is always clearer. Did anyone inspect your chipped counters prior to their installation? So sorry this happened to you.

Do you own the land and hired the builder? Or is this a build where the builder owns the land and house, and you’re buying it at closing?

Either way, the industry standard viewing distance is not 3” from the surface. It is standing 3’ back, in normal lighting. You're not gonna look supermodel from 3” either either.

Chips are normal, and are to be expected. Learn how to repair them yourself, or you’ll be spending lots of money paying to have them repaired. Read your warranty. Quartz is not warrantied against chipping.

Seams need a bit more epoxy fill. Not fatal.

I am a fabricator. +1 to Joe's comments. Those seams would have to improve to be bad. Re: the 72" piece; the fabricator didn't have a big enough piece left after the kitchen pieces either because there just wasn't enough material in the 1st place (his mistake), or it was sawn incorrectly (also his mistake), or an error was made in fabrication requiring a do-over (again his mistake). In any case they owe you a 72" piece without a seam. Unfortunately your fabricator is obviously a crap operator who either doesn't know or doesn't care how to do a decent job.

Thanks to all for your replies. i asked for a meeting at the new house with the quartz shop manager, shop owner and the builder. Builder agreed that a seam was not needed in the butler’s pantry and said he would replace at his cost. Since there is a piece from the butler’s pantry that is large enough for the powder room vanity, they are going to use it to replace the countertop that was chipped. As far as the unsightly seam, they agreed that it was not done properly. My only concern is that they said they dont use the seam filler recommended by the quartz manufacturer becasue it yellows. i contacted Spectrum Quartz and was told they recommend Integra Adhesives and recommended White Chocolate (0300). Looking at the Integra website, for Sophistication, they have their super bonder rapid and super bonder zeroI. Does anyone have experience with these and do they yellow?

Integra is the gold standard for seaming adhesives. Any yellowing they're experiencing is because they're allowing ignorant installers to mix their own colors and catalyst. They want a quick kick, so they add too much catalyst which causes the yellowing they're experiencing.

Integra comes in a 2-part tube that fits in a gun with a dispensing tip that mixes. Uncap the tubes, install the tip, put it in the gun, pull the trigger, and bleed the first blast into a paper towel. Now dispense the perfectly mixed and color matched adhesive to the edges to be seamed. Installer discretion has been eliminated as has yellowing.

Either Super Bonder Rapid or Super Bonder Zero will be fine.

"This unique adhesive will not yellow, stain, or bleed making it perfect for white marbles."

I've been using Integra for 25 years and have never gotten a failed or yellowing seam callback.
