Excellent work by the whole team from quotation, work done, cleanup, and followup questions. Everything explained, expectations set properly, no surprises along the way. In my case I was replacing an old Velux skylight that I'd been less than impressed with (but was not leaking): always felt cold underneath it (turns out improper installation by builder), screen had been improperly installed leaving a gap for bugs to enter if i opened it, and was showing signs of approaching deterioration. I just installed the manual crank Velux b/c money was a consideration. I don't know if I would have been happier with the rain-sensor instead, but that's not a fault of this team. Their work was terrific. I would recommend them.
