Granite countertop gaps - poor install?
I am hoping to find some assistance with the attached photo. Two months ago I contacted a BBB accredited and highly recommended granite fabricator and installer. The owner came to my house, created templates, and at my request, created templates with the specification that we did not want a backsplash installed at this time.
The granite has been installed. The attached photo is what I have throughout my kitchen - gaps spanning from 3/8 of an inch up to 1/2 of an inch. Some of these gaps are between the granite and cabinet walls and some of the gaps are between the granite and the drywall.
This granite was installed 3 days ago, and since then, my attempts to install a subway tile backsplash are very frustrating due to the fact that the gap makes the bottom edge look messy due to the large gap. Also note the 1/4 inch gap on the front of the granite tops between the counter and the cabinet wall - this is very noticeable and cannot be covered up by a backsplash.
The fabricator has told me that I should use a larger trowel - up to 1/2 inch, to smooth on more mastic to feather out the wall to bring the subway tile out more in the areas where there is a large gap...in my opinion this will form a wave or a bow in the wall. It was my impression that creating templates for the granite should have eliminated this problem completely.
Is this an acceptable install? Am I insane to think that a template should have fixed these unsightly gaps when I specifically requested that the granite be templated for "no backsplash" at all? I appreciate any insight you can provide. If any of you think that a 1/2 trowel will really fix my problem, I am all ears...
