"True to their word the insulation and ground vapor barrier they added to our crawl space absolutely helped prevent moisture (and radon) ingress and keep our mudroom above better controlled - we can already feel the difference in floor temp just in the first couple of weeks. We worked with several folks of their team and everyone was tip notch from the quote to logistics to the customer service throughout - they let us reschedule our smaller job a few times due to some logistical complications and when they had some of their own they made sure to make things right with their service (comping a hotel room we needed for spray foaming when they unexpectedly rescheduled the day of). Thanks Dain and the Gunner Team!"

"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."

"John and his team did amazing work removing the old, insufficient insulation in the attic of my nearly 120 year old home and replacing it with a much higher R-value blow-in insulation. The difference in the look of the attic is phenomenal, and I am confident it will be good for the energy efficiency of our home as well. The entire project took around 8 hours and the team even cleaned up to the point where you could hardly tell any work was done. I found dealing with John and Spray Foam Insulation Systems to be a very pleasant experience. Very honest and forthright, while offering a very fair rate for the work. I highly recommend working with them."

"Their guys were on time, professional, and communicated exactly what they were going to do as well as how long it would take them They finished what I was sure would be a 2 day job in a single day which was very convenient,. The foam applicator explained the technical aspects of the requirements for it's application, as well as making it very cosmetically appealing and consisent. They beat several other companies on price and exceeded the service you'd expect from the cheapest bid by a mile. Would hire or recommend them to anybody for any and all insulation needs."

FAQs for spray foam insulation projects in Saint Joseph, MN

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
