Fox Cities RetroFoam of Wausau, sent two workman, Zach and Alex, to install foam insulation in our walls. We own an old manufactured home which needed new insulation badly. The two man crew showed up on time (9am), introduced themselves and promptly went to work. Finishing the South side and east end, they reported in to us and left for the day. They returned the next day promptly at 9am and again went right to work. Finishing up the North side and West end they cleaned up any mess they might have made. Couldn't even tell they had been here. Very happy with the crew and their work. Was it worth the cost? Too early to tell. We heat with propane. It's refreshed on a keep fill basis and we have a couple of weeks to go before the refill. I'll repost here the results. But, so far the house seems less drafty. We're happy.
