crack in granite counter top at corner of sink

Crack has developed only at the right front corner of the sink, 2.5 weeks after installation in a still vacant unit. A 4' level shows space beggining between the level and the rest of the sink. The slab going to the left is also loose at the seam & is unstable, moving downward when you press on it. Installer says someone stepped on it. Accumulated dust on counter top shows no sign of being stepped upon. Other surface areas will oh so slightly show movement when pressed down. Is this indications of faulty installation or should I just live with it?

 

Dear Lynn:

 

“ Is this indications of faulty installation ”

 

Huge time!! L

Have your “Michelangelo” replace the broken piece and make sure that the installation is done properly – hoping that he knows how.

If the installation is done properly it doesn't really matter if someone steps on the countertop.

It is not recommendable, of course, but occasionally nothing would happen.

The countertop must be solidly bond to the top of the cabinets and no movement should ever be allowed, let alone felt the way you can feel it!

And when everything will be done to your satisfaction…

Remember, it's never too early to think about the proper maintenance of your stone. The issue of what you'll be doing day in and day out to your stone is – as it should be intuitive – vastly more important than its sealing (if and when possible and/or advisable) and it's all too often neglected. As you can tell by reading many of this site's postings, you're not likely to get good information about routine care from your dealer or installer. Don't become another statistic!
