“Greg Schwartz provided more detailed technical information than sales reps from other companies I considered. Young Kim was professional, courteous, and detail oriented (and spoke very highly of WoW).”

Review by
11/10/2019

“(1) Brandon Shonebarger, the sales associate, looked over our house thoroughly, answered our questions, estimated the job accurately, and explained the process and products very well. He was readily available to answer questions as we settled on a contract.(2) Young Kim, the project manager, and his installation crew were outstanding. They arrived promptly, worked tirelessly, and were courteous and responsive at all times. They cleaned up thoroughly after each area of the house was done, and picked up debris in the yard at the end of the job. Mr. Kim is also a master craftsman who did a fantastic job of capping the curved trim around a half-round window. (4) Eric Novotny, the owner, showed up during the afternoon and helped with the installation of the barrier railing. He had reviewed the plans we sent, and was able to explain them to Mr. Kim. He also went the extra mile in replacing our doormat, which has been damaged by a foam spill.”
