Keith and Kevin were excellent workers they all were working in harmony. My family is truly looking forward to having a warmer home and a reduction in the gas bill.

    RetroFoam was very easy to work with, proactive and professional. The estimate was less than I thought the price would be, their team was communicative and worked around a scheduling conflict I had and were otherwise pleasant. The work that was promised was completed in a professional manner with a large crew and done in less than half a day. We had one concern that was addressed immediately at no cost to us, by a firm hired by RetroFoam. The situation was repaired to better than previous condition. Bottom line, the second floor started out being 3 to 6 degrees warmer than the lower floor, after RetroFoam was done the temperatures leveled out to between 0 to a half degree difference, even on the warmest days. I was skeptical the results would be that good, but the combination of exterior wall foam and attic blow-in insulation and new batting really did the job. I would (and have) recommended RetroFoam to others. Special thanks to Stacey (scheduling and warranty work) and David (PM) and the crew(s) for a smooth experience.

    Short version: First, this was an upgrade that was worth the money. Second, they did an excellent job. The result: I was a little concerned about how effective this blown in foam would be. The original part of our home was built in 1901, there was no insulation, and there were some air leaks. But, the space for foam to be blown in was only 1 - 1 1/2 inches deep. That's not really much space, and that much foam does not have a high R value. But I did some research and learned a few thing about R value. First, the test for R value heavily favors fiberglass insulation. In actual use, foam is many, many times more effective than fiberglass. Foam seals air leaks, and the air in foam can't move freely, so there is no air circulation inside the insulation itself, in practice this means the colder it is outside, the better foam works compared to fiberglass. Next, foam deadens sound. Our house is near a road, so this was a consideration, but again, it was only going to be 1 - 1 1/2 inches deep, how much difference would it make? I waited a couple months before writing this. I wanted to have some cold weather so we could get a feel for how well it worked. The difference is huge. In the older part of the house, anytime then temp outside fell below 50, it felt "chilly." The outside air would leak into the walls and make that heavy old hand applied plaster feel icy. Now, after a 30 degree night, the old part of the house felt like the newer part (the part with lots of modern insulation.) The walls were warm to touch, and the split system heater barely ran at all. The Retrofoam insulation does an excellent job. The difference can be felt just standing in that part of the house. The sound reduction was substantial. We have a many windows, and they admit a lot of sound. The fact that we noticed the reduction at all is remarkable, let alone a large difference. I anticipate a significant reduction in heating costs. However, the money was well spent just from a comfort standpoint, the original part of the house no longer feels chilly. The salesman that came by initially to give us a quote simply said it was going to make a big difference. He was far too polite to say "you are not going to believe how good this stuff is, you would be silly not to do this." The install: Because of the type of siding on our house, the foam had to be blown in through the inside walls. Hundreds of holes had to be drilled to do the job correctly. We agreed to do the finish work ourselves to keep cost lower. The crew: Mike, Kenny, Keith and Martin did an excellent job. They were respectful of our property, placing paper all over the floors prior to starting work, and carefully cleaning up after what was a very messy job. After they left, there was no smell from the foam, and I only found one small dab of foam that got blown onto an inconspicuous spot on a light fixture. The spot was easily cleaned by knocking it off and wiping the residual up with water. My wife and I were amazed that they managed to clean up so meticulously that we only found one very tiny, near impossible to notice, spot they missed! The crew took their work seriously, going way out of their way to make sure the foam filled every wall cavity completely. There was a space behind the kitchen counter that I did not expect they could fill, but Mike figured out a way to fill it with a single small hole in the cabinet back. It took us a few days to finish off the holes and repaint. The end result is that no one will ever notice that hundreds of holes were drilled. I understand the foam can usually be installed from the outside, so don't worry about this! My advice: don't hesitate to go with Retrofoam. Great product, great install, great results. Well worth the investment
