We just had our counters replaced in our kitchen and it looks great but I pointed out several things to the installer and they acted as if I was crazy about some of them. Is what they did ok? Am I off base asking them for some resolution? Pictures here since I can only upload 3 - https://photos.app.goo.gl/MLeC2awLekoZb9Ws6

- shims under stone are clearly visible - seems odd. They had to use shims because the last counters were installed using a thick adhesive and they didn’t remove it from the backside of the cabinet - which required them to shim front (they didn’t tell me that but I can see the backside looking under the cabinets). You can also see the seam isn’t completely filled which I asked them to fix since it goes up on the side and is visible.

- black flake in the stone - it looks almost like something slipped in during the stone manufacturing- they told me they couldn’t do anything about it but surely this would be covered by the stone manufacturer? There is NO black color in the stone at all

- undermount sink is being held up with silicone and wood braces screwed into the side of the cabinet - they told me “we can remove the wood braces and the silicone will be strong enough to hold the sink” and they’ve been doing it like that for 20 years... I checked and the sink (Blanco) states they should use brackets or the warranty is void. Our last sink was mounted into brackets cut into the granite.

- top eat at counter has a straight angle on one curve (where the seam is) but the other side they rounded it - it’s not symmetrical at all. This can’t be normal? They said they could come and cut it at the house to make the rounded side a Straight angle to match. Should they do that on-site? Feel like there’s a large room for error doing that by hand

- chunk on the underside of the cooktop cutout - does this change the integrity of the stone?

Lastly, no adhesive was used - is that normal? They just set the stone and siliconed around the edges.

thanks for the help.
