The cost to replace countertops is largely determined by the material of the counter, the removal of the existing countertop, and if any plumbing or electrical services will need to be moved and/or reinstalled during the installation process. Also, the cost of labor is another large factor in determining cost. Some general price ranges of materials and labor costs include: Granite countertops: $15 to $140 per square foot for material. For material and installation labor you are looking at between 25$ and $170 per square foot. Soapstone: $20 to $70 per square foot for material. For material and installation, you can expect to pay between $30 and $100 per square foot. Marble: $15 to $190 per square foot for material. For material and installation, the price ranges from $25 to $220 per square foot. There are other materials with lower costs that keep the prices well below $100 per square foot. They can include slate, limestone, and travertine. When choosing a material for your new kitchen counters remember that by paying a little more upfront, you can add longevity to the life of your kitchen countertops which could save you money in the end. That is why so many homeowners are choosing granite as their choice.
