Cracked frames should have been rejected at delivery. Nothing you can do after install except clamps and glue and touch up. Anything inside the cabinet is mostly fine. The poor caulk and touchup job for sure needs a better touch up finisher. Your microvave needs the trim kit if you want it to ”fit” in that like a built in. That’s how a standard microwave shelf is built.

Nothing is critical here. Some of it is normal, like the shelf being a tad short on cut, and the visible seams between the different joined pieces of the cabinet. No painted cabinet will ever look seamless. And the changing humidity will cause even more telegraphing of cabinet wood joins. That is life with painted cabinets. Its normal. That should be covered in an Expectations conversation and document. Also covered should be your responsibility to maintain indoor humidity between 30-60% in order to minimize that issue and maintain your warranty.

They need to pay for a Furniture Medic visit, and have someone on staff watching how they do it. It can be better than it is. But it is far from as bad as you think it is.

Amy - I’m so sorry :( You paid good $ for this and expected more - so disappointing! It looks like at least one of your cracks is under the countertop, so unless you remove it (the countertop) there’s probably nothing to do on that cabinet. We had a custom home built in the mountains in CO and it was flawless (ok, nothing is ever truly “flawless”) so that set the bar very high for our recent whole house remodel. Worst decision we ever made was to have the carpenter install the cabinets, vs the cabinet maker. That ship has sailed though (and GC did make a few things right for us at a hit to his bottom line). I hope they can at the very least cosmetically get it to where things look better.

The seams between cabinets don't bother me except where the wood is chipped along the seam, but they randomly caulked some seams and not others, which I don't understand, and it looks sloppy. And will the caulk hinder movement as the wood expands and contracts?

The cracks in the frame (there are 5 of them that I've found so far, all on the outside frames except for the one by the screw) are all in areas that can't be clamped. Should I be concerned about the cracks growing over time? I'm not sure if the pieces arrived damaged or if it happened during the install, but I'm unpleasantly surprised that the PM let it all slide, not only initially but after the fix day. Our friends are currently renovating with a different company and their PM ensures everything is fixed flawlessly, so it's super frustrating.

Re: the microwave, the one they purchased hangs slightly over the ledge... will a trim kit still work in that case?

I am sorry, You are going through this. Honestly, I cannot comprehend in my head that we are expected to accept sloppy job. It happend to me in new construction with the trim job. Sloppiness, carelessness, I stood my ground and most was fixed.
