    Areas of Expertise

    • Wall Cavity Injection RetroFoam Insulation is a game-changing foam insulation material that completely fills wall cavities, adds major R-value and lasts for many more years than traditional materials.
    • Spray foam is the perfect choice for any project that has an open wall, floor or ceiling cavity. It has high R-value, the ability to bond directly to wood and can mold itself around any obstacle.
    • We perform detailed air sealing in every attic space we work on. That's how we can guarantee insulation improvement. This can include RetroFoam, spray foam and any existing insulation like fiberglass.
    • There are many areas of your home that need to be sealed, some more obvious than others. We follow a professional, focused process to make sure your home is fully sealed to increase efficiency.
    • Energy Audits & Blower Doors - This signature test of home performance offers data about air leakage that can be compared not only to other homes, but also as a before and after look at your project.

    We hired RetroGreen to install foamed-in-place insulation in our house, which was built in 1960, with only 2" of wall insulation. For most houses, which have horizontal siding, installation is fairly simple. Our house has vertical board and batten siding, which makes the project more difficult. The installer can't simply remove a couple of courses of siding, do the work, and replace the siding. One approach for board and batten siding is to drill holes through the boards and insert plugs after installing the insulation. No matter how carefully this is done, I suspect the result would be visually unacceptable, with rows of obvious plugs around the house. Instead, I asked them to drill holes only behind the battens. I removed all of the battens, first marking the sides, RetroGreen skillfully drilled their holes within the lines, so when I replaced the battens, all of the holes were concealed. In one small area, that didn't work, so they provided plugs that closely matched the siding boards. Chris was quite helpful throughout the process, discussing options and making suggestions. The team was professional and efficient, providing protection and cleaning up on completion. The result is excellent; there is no visual evidence of the installation.

    The main individual started out polite and everything seemed fine. However, when they did the actual work, the quality was poor and I had to ask them to correct NUMEROUS areas where they had no more than 1/2â of insulation, gaps, etc. I paid them $2600 for ONE ROOM. He became very rude when I asked him to correct items that were complete gaps, and he had the gall to rudely hand me a razor blade to cut away the areas they left sticking out well past the window edges . Worse yet, they had many areas sticking out well past the height of the 2x2â s so that it would have been impossible to install the Sheetrock! I had to have them fix many items and even then I had to correct several things myself at $100+ an hour my rate to trim / fix various areas ....


    Professional and courteous. The folks on site took time to answer any question, wore masks and cleaned up well. They did great job painting the stucco after insulation and patching - house looks great. The insulation is already making huge difference in my 1911 house in Minneapolis- not sure the boiler will kick in till December.

    Great job, no complaints

    These "experts" told us our problem with ice dams would significantly improve and our energy bills would be reduced by replacing and upgrading our insulation in the attic. We paid them over $13,000 and the result- ice dams got WORSE and the energy bills didn't go down. We asked them to re-evaluate. They admitted they should have done some vents and other things differently, and said they'd return to make those corrections. Guess what....they never showed up and now they won't return our calls or emails. Needless to say, we are very disappointed. We threw $13,000 down the drain. Do not use this company. Go elsewhere.
