When I called The Solar Guys I had no experience with solar tubes. All of the information was explained from A to Z, including pricing and tax rebates. I had them come out, I should say, him come out. I was surprised to see one person take care of the whole installation. He did a great job, and except for the wonderful light shining into my room, you’d never know he had been there. I love my solar tube, Thank You, Jen H.
