When you update your cook-top chances are that you will need to expand the existing cutout of your stone to fit it. While in the process of resizing we also brace and reinforce your stone while your old cook-top is taken off, assuring that you will not be breaking your stone top any time soon. This process does create a little dust, so we bring out a shop-vac and try to contain as much of the dust as possible. We do ask that you cover or remove anything that you do not want to get dusty. You should expect some dust clean up to be done.
