Your new granite looks great. Regarding the edge treatment, yes, that is what is done when you go with a 2 cm. granite. The edge is built up and laminated to look thicker. All of my granite counters are done that way; however, my seams are not very visable. Yours looks like it was not buffed or polished smooth. I'd ask the installer about it as perhaps they need to come back and polish it smooth. You may want to post a question over on the kitchen forum about your edges as there are some granite experts there who can say better what, if anything, is wrong and what, if anything, should be done.

These are my pics of my countertops placed Friday June 22, 2018. I cried looking at these seams. It looks so cheap. Fabricator explains that's the way it comes. I explained that I shouldn't be able to see the seams so clearly. It looks so unprofessional. They ended up taking them back to their warehouse. In hopes they say if it is quality control will try and fix it just to make it look better. Otherwise I will have to pay an additional fee for them to come out again to install. I just don't know what to do and if still looks the same. This is the first time I've replaced my counters in 24 years. I don't and can't live with it. looking at this for another 24 years. It looks so cheap and it really was not it's a lot of money to me. I hope fingers crossed that they will fix this problem. They never told me that there would be such seams. I thought the edges were done by a machine and it would be all one piece. I have read up on this and now understand there are seams. But now I do know that they should not look like this. If they are good fabricator you shouldn't be able to see them so clearly. I will find out next week what happens.

Thanks to graniteshop for jumping in here. Now that I have seen what an air vent is (they are not required in my area), I have a better understandiung of why it may have cracked. Another fabricator wrote the following: "The hole for the vent is drilled all the way through the material like a faucet hole and is most likely an 1-3/8" diameter just like the rest of the faucet holes. There could be a couple causes of the crack. It could have been cracked during the install and not noticed until this point. It's also possible that they crack was caused when the hole was drilled. If they did it on site with the wrong style core bit enough heat could have been built up to cause the stone to crack. Also, if the cabinets were not level or if the top was not properly shimmed the top could crack after install. If the top was cracked before install it will still probably be perfectly flat. If it was cracked after install then you may be able to look down the top and see either a high point or low point in the top at the location of the crack. " Seems like good info to me.

We have had almost the exact same issue with our corian. The builder wouldn't even come to check it only went by the pictures we sent. Then blamed it all on something "very hot" had to do that! I can tell you now, it did not. There is also a large dip or warp over the dishwasher. When we pulled it out there is absolutely no heat barrier or insulation to protect the corian. The installer also never sealed the sink basin. Which we found out the hard way when our sink overflowed. The installer/builder takes no blame Won't even come to look or tell us what we can do. There is a ten year warranty on the corian, we've been fighting this for over two years now. The ten year warranty will be up in September of this year. What can we do???
