For all those Replacement Window questions
I would not want to invest thousands of dollars with a company that could be gone tomorrow. To me, that means anybody that does not have roots meaning either a brick and mortar location, membership in all of the trade and consumer organizations, etc, and/or many years of history in business. I think that you really need to of those three to feel comfortable with a company. Some one-man operations have that, many(if not most) don't.
