Granite Transformations charges about $40 to $80 per square foot plus labor, with their countertops coming with a lifetime limited warranty.. Their labor rate pushes the cost up to $100 to $130 for each square foot, depending on the project details.  The company only installs veneer pieces that go right over the existing countertops. This saves money on demo and disposal and takes much less time to complete. They don’t sell the modular pieces separately for DIY projects, and they don’t allow you to measure your own countertops.
