The short answer is yes. Although we carry the necessary insurance to protect your home while our employees are on the job, decisions often need to be made regarding the final installation that only you (or your representative) can make. Also, we require final payment for the countertop at the time of installation. NOTE: some of the sealants and adhesives may have noxious odors. Those who are sensitive may vacate the premises. These odors will dissipate over a few hours after install is complete.
