Delivered here and everyone is professional and friendly. .6 miles from Loves truckstop Fondulac Wisc
I've been a insulation contractor for over 31 yrs. In all that time I have rarely found a product insofar as cellulose as high a quality as champions. It blows well..its coverage is spot on..its not overly dusty like other manufacturers. It's a good product that we are proud to use in our business.its a great value!
This looks like a recycling warehouse. Brought scrap paper here today. So it's probably not an installation place unless it's recycling the materials for insulation But they are open at 7:30 in the morning

I was impressed with Brian Aho during the initial site visit to get a quote. He listened to my concerns and was able to answer all my questions. Brian quoted the job based on what I wanted done, he did not try to upsell anything beyond what I asked. The communication was very good throughout the entire process. The installers, Jaxon & Logan were very professional, polite, on time, and kept me up to date on the progress of the project during the day. The truck, trailer and equipment were all in very nice condition. They were efficient and considerate within my home. I have a winding staircase with freshly painted walls and somewhat fancy trim work, and Jaxon & Logan were very careful handling their very long blown insulation hose through my front entrance while navigating it up to the second floor attic. They cleaned up after themselves to the point that when they left, I couldn’t even tell they were here. Nice work start to finish. I would recommend Koala to my friends and family without hesitation.
Excellent experience yesterday with my attic insulation installation! ⭐️⭐️⭐️⭐️⭐️ Jaxon and Logan arrived exactly when they said they would, and they were friendly, professional, and very knowledgeable. These guys had to climb up on my very high, steep roof to install the roof vent for my bathroom fan, and it was no problem for them. 😅 They got the whole job done without any issues and without any mess. Great focused team! I have a big leaky old 150-year-old farmhouse. I got a few quotes, and Koala Insulation was able to re-vent my bathroom fan through the roof, air-seal the attic, spray a non-toxic cleansing spray, install an air-seal zipper door, and install thicker insulation than the other guys, ALL for a lower price than the other guys quoted me for just basic insulation! It’s down to 50 degrees outside this morning, and usually my furnace would’ve kicked in by now. But the house feels warm and the furnace isn’t running yet. NICE. 😊 Really happy with this job, looking forward to being warm this winter!!!
We had insulation blown into two attics. Both of which were not that easy to get into. Both Jaxon and Logan were courteous, and knew their job well. Could answer questions easily. They cleaned up nicely after themselves. All in all very nice young men. And the job was done efficiently and perfectly. Would highly recommend Koala insulation. Customer service from start to finish was seamless.

I just had them spray the inside of my 12'x16' cabin in the woods. They did the walls, ceiling, and floor joists (2x4).Everything from their timeliness to replying to my initial inquiry, arranging to see my project, getting me a bid, getting me on the schedule, and getting my project completed was nothing short of a pleasure. They kept me informed the whole time from start to finish. The gentleman that did the spraying was very meticulous and was careful to get every nook and cranny. When they were done, they did an excellent job of trimming the excess, caulking between all of the studs, floor, and top wall plates. They also did an excellent job cleaning up because this process does make a bit of a mess. I was really surprised at how much spray foam solidifies a structure! When they were done, I set up a lazer to start finishing the ceiling and when I walked around, the lazer line didn't move at all! My cabin sits on concrete blocks so it's not real sturdy to begin with but it feels really solid now. I'm in the trades myself and I firmly believe that you get what you pay for and I feel like I got what I paid for and I'm very happy with the job that was done. You can tell in the first 5 minutes of meeting any employee that they take pride in their work and it shows. Thanks a lot to everyone at Rock Road!
I first called Rock Road Company after another spray company that I had lined up had backed out of spraying my house the day before it was supposed to be sprayed. I explained to Carrie my situation along with the tight time line that I had for spraying before my drywall installers were scheduled to do their job. Carrie and Luyk made it a point to go out of their way to come measure my project the day after I called. Rock Road Company was out to my house spray foaming the very next week! The Rock Road crew was very knowledgeable and experienced. They did an excellent job prepping, spraying and cleaning up everything in my house. I will for sure be keeping their number in my contacts for future projects and referring them to anyone that is interested in spray foam. Thank you again Rock Road Company!
At first, I was skeptical about foam insulation for my building due to the perceived high cost. When I contacted Rock Road, they immediately set up an appointment, to which they followed up promptly. While my initial reaction to the bid was that it was high (as I expected,) Luyke and Carrie explained in detail all of the cost aspects of a foaming project. They explained the benefits of foam insulation in detail, which helped me understand the long term value of foam versus fiberglass or blown insulation. I decided to go with them. The crew payed high attention to preparing the job site with thorough masking to ensure all surrounding areas, appliances and fixtures are protected before beginning the spray. The prep work took up the majority of the time, far more than the actual spray (which was fascinating!) The Rock Road crew took tremendous care in their job clean-up; in fact, I was surprised that the clean up took nearly as long as the prep work and was impressed that there was not one spot of foam on a surface it wasn’t intended to be on. Upon completing their work, I was blown away that the final invoice was less than the initial quote. Carrie explained that they plan and bid for every issue and problem, seen and unseen. They do not want the customer surprised with additional costs. If the job goes smoothly with no hidden issues, Rock Road reduces the final invoice. They are more than fair. My experience with Rock Road far exceeded my expectations. I’ve had one year under my belt and I have to say my building is a giant YETI cooler! It took such a small amount of energy to heat and cool the structure that I saved a ton in fuel costs. It is also extremely quiet. The big picture of foam insulation is now clear to me. I highly recommend the Rock Road Company and will use them again in the future.

The warmer summer nights of climate change were pushing my 1909 arts and crafts bungalow to the point of uninhabitability, particularly on the second floor, by making it impossible to air out the house overnight. Cue A-A Exteriors coming to the rescue. Hunter P. worked with associates to design a comprehensive tune up for my home, top to bottom, with insulation, air sealing, and proper ventilation. Derek and James led the plan’s execution with a team of installers who worked tirelessly and with collegial good humor at tasks that were physically challenging and mentally tedious under varying conditions of comfort, or lack thereof, day after day. I never heard a cross word spoken or a voice raised over the course of more than two weeks of work. That’s leadership! Such an old house inevitably yields surprises, but the team problem-solved every challenge and completed every goal. Cory painstakingly documented my home’s condition pre- and post-construction, but I didn’t need data to know the company’s work has paid off. My home has been transformed, and not a day too soon given this summer’s hot nights and hotter days. Now I can enjoy the charm of an older home with the comfort of a new one. Thank you, A-A Exteriors!
Had excellent and responsive planning experiences with Torrance on a tricky insulation condition (uninsulated 2x4 rafter ceiling). Hunter was timely and professional running the Energy Audit and promptly followed up to answer questions I had. The insulation crews were efficient and professional. I would work with them again without hesitation.
We have the highest regard for Torrance and his team. Our 1960s home had numerous air-sealing deficiencies, some obvious and some insidious. AAE did not just do the easy things and say it is 'good enough'. They were committed to do the job right and solve the problems. Crew members were courteous and professional. Torrance has a better understanding of air sealing / insulation / ice dams than anyone I have met. Our dealings were honest and forthright. We recommend this team to anyone.

Had the basement rim joist air sealed/spray foam insulation done at my home yesterday and the technician Quintin did a fantastic job. Working with Matt was great and I would definitely recommend this company.
We needed our attic insulation replaced due to rodents. Contacted Matt and knew i made the correct call right away. Justin came out to inspect the attic and determine several problems. They were able to schedule us within two weeks. The very professional crew came out and kept everything as clean as when they got here. Found and fixed a few problems we didn't know about and finished the whole job in less than a day. Attic looks like new, all the fans are vented properly and things are sealed up as they should be now. Price was in line with other estimates but I know these guys do more than other companies do for the price. Would definitely recommend this company if you need new insulation or a complete replacement like we had done. Communication was great also.
Matt and his team were a pleasure to work with, all were very professional. We had vermiculite in our attic, and they were extremely professional on how to remove it without it getting in the house at all. The vermiculite did not once enter the house once. If I need to have more insulation work done, I will certainly work with Matt and his team again.

Kind of small facilities for a big 🚚 but nice people let me sleep on site when I was there had no shift time to drive to a truck stop
Ok
Today around 1030 one of your vehicles were driving very fast down agriculture and took a left on Femrite. He was swerving in and out of traffic cut a bus off and driving at high speed. I'm sorry but in no way would I use recommend your company when your employees act reckless. It is recorded.
