"Did not do work, but pricing was competitive with everyone else. Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again. If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!

"Ethan explained (in detail) how they would not only set up the panels on top of my home, but that they will also "pressurize" my home, including my air conditioning unit, to ensure that I get the best service possible from my panels! He explained every detail of cost, taxes, and best of all REBATES! He explained several methods of purchase, as well. I have his personal cell phone number in case I have questions, and I can call their office at ANY TIME if I need anything. So far, my experience with Sunpro Solar (Mandeville, LA) has been nothing short of great! In a few weeks, I'll have my solar panels installed. The time it has taken to get to this process has been minimal. Everyone I've spoken with at Sunpro Solar has been friendly, helpful, knowledgeable, respectful, and accommodating.
