"I have had Art come over and install a Solar Tube in our bathroom, which was awesome and not only do I recommend Art, I recommend Solar Tubes in general!!
We moved into a house recently that has 5 skylights in it, all of them were ancient and energy sieves. I had Art price up replacing with new energy efficient skylights, with solar blinds to add extra insulation. I'm so glad I did, as the old skylights were not only in bad shape, and energy inefficient, they had leaks, and were poorly installed. He put down drop cloths wherever he was working, and you'd never know the guys were there after they left. Can't ask for much more than that!!
My new Solar Tube, Velux skylights and solar blinds are awesome, and I know they were pricey, but wow...totally worth it."
