$300-$600 and a big mess, and the issue is fixed by a good stone fabricator.

@GreenDesigns thanks, wow, didn't know it would run that much. thanks so much

There’s a basement cost to anything involving skilled labor. It doesn’t matter what they do, there’s a minimum charge to do it. That holds true for any project. Most of the money going to the contractor is for him to start his truck and show up on site with all of his expensive tools, licenses, insurance, and 10-30 years of knowledge to do the job correctly. $300-$600 is very cheap in the world of stone fabrication. You can always put that 1/10th into upgrading the stone to a different choice.

@M thank You for the advice. The granite countertop overlaps the cabinet boxes, so there’s going to be room once the granite overlap is cut/trimmed. And thanks for that amazon link, I’ll look into that

i‘ve been using google search for “granite stone fabricators” in the area that I’m hoping can do the job, and it led to a list of granite suppliers businesses in the area. So should I be contacting those suppliers? I’ll be calling tomorrow morning and just wanna make sure those are the right people to call that can help me

M makes good points. I would be concerned that there isn’t sufficient room to slide range in even if you trim countertop. So measure side to side of cabinets top, bottom, front to back to ensure you have enough room. I would also check to see if you could exchange this range for narrower style.

How handy are you? If you can cover small mistakes with a filler strip or caulk then you might want to look into a grinder or saw with a diamond blade. You will need another set of hands to operate a shopvac for the dust. YouTube may have some videos showing people doing this themselves - it won't be a professional result and there is the risk of cracking the stone if you aren't lucky ... but anyone who guarantees to replace/repair any damage will be a pretty expensive hire.

Where are you located?

I live in Fresno CA

You need a true slide in range to go back in the hole, not a free standing. There is no good way to clean up the cuts so it doesn't look like a hack job.

"There is no good way to clean up the cuts so it doesn't look like a hack job."

I've done this job many times and none looked like a hack job. Budget $300.00-$600.00.

You want the new cuts perpendicular to the rear wall, I don't care what the cabinets are doing.

FYI: some slide-ins require the 'hack' job seen here, the front corners cut wider than the rest. The Electrolux was infamous for this.

You also need to remove the piece of granite counter behind the stove. The new range probably won't go back far enough with that piece in the way.

Just as a price comparison I’m getting 3 cuts in my quartz countertop to enlarge the cutout for a BlueStar cooktop. $500 via the appliance company, I didn’t shop it at all. So you‘re getting spot on advice.
