Bigger hole for a bigger cooktop

[StartAgain]

Howdy all,

I have done a search and am surprised I havnt come accross more posts similiar to mine.

I am updating the kitchen cooktop, and well, the new cooktop the mrs wants requires a larger hole than already exists. Now I dont plan on cutting it myself as it's granite, and lets face it I dont want to stuff it.

My questions are
Can it be done on site?
How much of a mess will they make?
Can anyone recommend stonemason?
Rouch cost on making a hole that's 860mmx480mm to 916mmx500mm

Thanks in advance
(I bloody love this site)

Howdy all,

Absolutely...this is how it is often done.

How much of a mess will they make?
Empty your cupboards and seal your doorways - think of a dirty big grinder spraying powdered granite...

Can anyone recommend stonemason?
Where are you?

( my Brisbane contractor would be looking at around $200 or so to walk in, cut the hole and leave, depending on the variables of the job)


Hope this helps a bit...

As Earl says it is mostly done on site to avoid turning up with wrong size hole. Also transporting a slab of granite with a dirty great hole in it would greatly increase the chance of it breaking.

Earl, Do you think they'll need to remove the granite to make the cut?

When they cut ours on-site they did it outside on the driveway and the dust was incredible, wouldn't have wanted that in the house.

Does the new cooktop come with a template as the guy cutting the granite will feel a lot more secure with this than with some dimensions scribbled on a fag packet. The manufacturers website may have details on the hole required if a template is not supplied.

Ripping.

Thanks Guys.

Yeah I have the specs got them from the Miele website, but not the cooktop yet, I was holding off until i had prices.

BTW I am in Sydney.

Not sure about removing the bechtop though. Its a massive L shape, glued in pieces siliconed in to the tile splash backs and cupboards.

As for mess, expected as much, but if she wants this fandangle induction european cooktop, she can clean up the mess the guys leaves. fare 'nough I say!?

Make sure you give the guy the spec for the hole not the size of the cookdoh::U

Oh man, you would not believe how often this happens, especially to guys with years of experience.

Draw line around sink; Cut hole; Put sink in hole; watch sink fall through hole...

Template or similar is essential.
If you don't have a template, put the cooktop on the bench (upside down if possible) and mark around the edge with masking tape.
Then put another line of tape around the inside of the new perimeter and scribe an appropriately offset line for the hole to be cut.

By the sounds of things the top is going to have to be cut in situ.
The actual cutting process shouldn't be any different, but if there is any joinery underneath the top, such as carcass gables then these might also need to be modified.

Any competent mason/stone top installer should be able to rise to this sort of challenge.

As for the dust, well, you have been warned and from your response you seem to have a proceedure to deal with this - but wait till she sees the real thing!

I would still recommend sealing any doorways with plastic if possible (hopefully it's not an open plan kitchen) - it's just like getting floors sanded...

Cheers,
