Dear Cavalier,

You can be very proud of the two gentlemen that were here installing the radon mitigation system.

They were very courteous and extremely mindful of our home. They made sure everything was protected before starting and meticulous with their work. They were very professional both in their attitudes and work. They were careful to make sure they cleaned up any mess including on their hands and knees wiping up dirt particles, which I convinced them I could get with the vacuumed cleaner. They made a very good team, and it's professionals like these that should be wearing the yellow capes you see in commercials on TV.

Again, I want to thank them very much

Dear Cavalier Radon, Warren and Sylvia,

            Just a note to let you know that my wife and I are very pleased at the professional installation of our radon mitigation venting by your crew. My wife was afraid that she would lose her sewing table space in our rather small and crowded basement, but the crew carefully worked around it, hiding most of it behind a cramped wall. It was a well thought-out and neatly done job. Thank you!

Dear Cavalier,

We appreciate the good work done by your staff. On the first tests after the work was initially completed, the level was still above the acceptable range. We were impressed that you promptly acted in correcting the situation.

We just received the radon test results this evening - 3.8 and 3.6 pCi/L.

Again, thank you and your company for excellent work.

Sincerely,

Betty & Gary
