The naturally porous surface of stone needs to be regularly sealed to repel water-and oil-based stains. Soapstone is soft and most prone to chipping. Professionals can often polish small scratches and chips from your countertop. Cleaning and polishing can also restore the shine back to stone which has become dull and hazy. If a solid stone surface cracks, the entire countertop will need to be replaced.
Set your thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
