"I was not particularly pleased with being cornered to make a decision about the project the same day I received a quote, particularly since window treatments were going to be for the whole house. It is a business tactic; I get it. Regardless, we ended up with this company after making an informed decision. How the company responds to our questions and any potential repairs down the road (if there are any) is still something to be determined. So far, we have been generally pleased with the shades."

"I can't say enough good things about Bob and his team. He was the only tinting company I actually got a call back from the first day, and worked hard to provide incredible services within my tight window (no pun intended!). Bob was knowledgeable, friendly, and flexible, and the installer Mike was very talented and punctual. Bob warned of a potential for small cracks between the window and the tint but you would have thought the tint was a part of the actual window. I would hire them 100x over and cannot recommend them enough."
