"Greatly appreciated working with Ryan Hawkins. He came on time, completed his inspection, and submitted the report shortly after. Thus, allowing us to submit the report to the seller in a timely manner."

"They were prompt, efficient and courteous. They called to let me know they were on their way and cleaned up everything when they were done. They were supposed to explain something to me about some monitor after the installation, but they forgot. They did walk through how to do the radon test in another week. they also gave me a senior discount, which was definitely appreciated. Otherwise, their pricing was pretty much in the range with the other estimates I received."

"Zach Shipley of Clear Environmental took on the task of removing my extremely large inground swimming pool, filling the cavity and resodding the lawn. He and his crew were very professional in all aspects and he was very "hands-on" throughout the entire process. He was on-site for delivereies and to oversee the work and to keep me apprised of everything that was being done and how the job was progressing. It was a monumental job and he made it as painless as possible at a very competitive price. I would highly recommend Clear Environmental to anyone with a home or commercial project."
