"Shane and his partner treated our mold issue with great concern and professionalism from the time I called them. I was originally denied by my insurance company and they determined the root cause of the mold was not what the insurance company denied me for. As a result, my claim is now being approved. I can't speak highly enough for Shane and how much he went above and beyond his job duties to help me out and defend our case more than any contractor I have ever worked with. A big THANK YOU to Environmental Science Services! If you ever have a mold or asbestos issue, call Shane!"

"While replacing our floors should have been an easy task, we were beyond bummed to learn that our old linoleum contained asbestos. Begrudgingly, I started calling around to get quotes on abatement and called Select Environmental on the recommendation of a friend of mine. Despite the fact that asbestos removal wasn't in my budget, I simply could not be more pleased to have found Blake and his team. From the outset, they were fast, timely, upfront, honest, and their pricing was fair. When an appointment was made for 8AM, my doorbell would ring at 7:59AM. His workers were efficient, meticulous, and courteous. By the end of our project, I almost longed to discover more asbestos so that I could use Blake and his team again. All kidding aside, I highly recommend Select Environmental and will use them again should the need arise."

"From start to finish, they did an excellent job. My husband's comment was: "I've never seen such a great job".
I told Rick we had a lot of stuff to move before they could start, he told me not to worry about it, they would move everything. When they were finished, not only did they clean up their mess, they put all the patio furniture back. The crew that came to our house were extremely nice and hard working.
We have another house that will need paint next year and I will be calling Rick to do the job. I just can't say enough about this company.

"They worked hard removing all the finish and applying the first coat of stain and sealant. They have come back two more time to sand and reveal to ensure a smooth finish as requested. They are always on time. I would reuse their service Nice people

"I am very excited to say I had a great experience with this company. Friendly, professional people. The project went exactly how I wanted it to go. I had pretty much every room in my house renovated, including the bathrooms (new Jacuzzi, shower, sink, toilet, floors.. etc.), a new fireplace, new floors, new doors, and fresh paint. I am absolutely in love! I contacted Spectrum One on 12/2/16 and they finished my entire house just in time for the holidays! Thank you!!"
