Hairline Cracks in New Granite
We have just installed new granite countertop.
The cutout for the stove top was too small, but the installer shoved the stove top into the space.
Now there are hairline cracks radiating out from three of the four corners of the cook top hole
and the stove top is broken.
One of them goes all the way through the slab. The others seem to be on the surface. Should we make them replace the granite countertop?
They haven't even hooked up sink or stove top yet. They claim epoxy will solve the problem.
ANSWER: I'd make them replace the granite.
Considering they couldn't think ahead or be patient enough to do the job right, I wouldn't trust any countertop repair job they were going to attempt.
A single hairline crack somewhere, I wouldn't worry about, but multiple cracks radiating from 3 corners of the cook top cut-out... no good. You will be constantly stressing this area
too with additional weight and pots and pans banging around (if you cook like me anyway!).
Plus, with so many cracks concentrated in small areas, they may get worse
with more becoming full thickness.
True, epoxy or polyester resin could repair the cracked granite
and improve the integrity in the area, but cut-outs are weak areas.
Even with repair and any support that they may be able to add the entire area is compromised.
Epoxy can be very strong and a stellar repair may be sufficient, but I'd want a granite repair specialist to do it.
Now, I don't know how long or how many cracks there are, so maybe it sounds worse than it is and you're thinking maybe just to negotiate a much cheaper price and an adequate repair.
That's an option...However, there is still the issue of the broken cook top.
You need a new one... the same one won't fit this cut out. So, you need one that will fit this cut out because enlarging the cut out now is risky
... could wreck the slab.
Maybe you get lucky and find one, but this is a bassackwards way of doing it.
I say start over.
