You are certainly welcome to do this. However, most countertop shops have access to the same stones, and it’s probably simplest to start and finish your project with the same company. You do want to be mindful of the reputation that each company has for fabrication or installation. Countertop Concepts is a fully digital shop, utilizing digital templating and robot saws that cut with near-perfect precision (removing the chance of human error in cutting the stone). Our installers each have decades of experience in installing stone surfaces, and we take great pride in every countertop installation.
