Dan and his workers were great do work with. Dan was very responsive and proactive. He returned my calls in a timely manner, showed up when he said he would, did quality work and had fair pricing. My project was a 900 sq. foot exterior building building and they blew insulation into the attic.
After doing a great job on my crawl space I am asking them to do the remainder of my 2100 SF farmhouse remodel.

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.

When building our new modular home we decided to have a 32x32 attached garage built with an attic for storage with access from a typical stairway. Driving to and from our place we would see the Comfort Pro building from the highway. I did some checking and found good reviews on this very same google platform so I called. I was put in touch with Gary, who has since retired, and he was absolutely great to work with. He was timely in providing an estimate and was very honest about timing since this was at the height of covid. Gary indicated several times that it would happen on short notice, and it did indeed, but with Gary continually keeping in contact kept us at the ready by having electrical etc., completed. The applicator(s) were awesome having covered everything as well as working with a couple of other contractors on-site to move a few things around. Outside of foaming two sets of rolled up wires for outside lights (my fault) the job was perfect. We would definitely use them again. December 2023 Update: We used Comfort Pro once again to work on our Box Sills all around the basement. The two guys were on time and did an awesome job removing the Fiberglass Bat insulation then spraying the same foam insulation as we had installed in our garage. Again, I can't say enough about the two gentleman who came to do our project as well as Sean Capelle who provided the estimate and scheduled the work with us. Very accommodating. Thank You!!!
Great experience with Comfort Pro Insulators. Sean was quick to respond to my calls, met me at my cabin and we discussed that I was having an issue with the duct work under the house and the AC not working properly. His guys showed up on time and sprayed the whole underside of the cabin including the duct work. Twenty minutes after they finished, I turned on the AC and it now works like it should as they spray sealed all of the underside duct work!
Sean and the Comfort Pro team were great to work with for my insulation project. They were very thorough when walking through the different options for me in order to turn my exterior garage into a comfortable space in the summer/winter. Always easy to get ahold of for any questions I had during the process as well!

Dan did an exceptional job explaining the necessity of proper attic insulation and the benefits it would provide to our family. He took time to point out what immediate needs were and how his team could address them effectively and efficiently. Dan and his crew are friendly, professional, and good around both dogs and kids! We appreciate their time, hardwork, and thoughtfulness. We will highly recommend Home Energy Solutions of Wisconsin to others! Thanks again! 🏡
I called about moisture issues we are experiencing in our new construction home (the insulation was done by a different contractor) and Dan was so helpful in explaining what we were likely experiencing. He recommended we try simple, much less expensive options that we could test on our own before paying to have him come out to assess. He took time to ask questions and provide thoughtful insights to help us troubleshoot. It was so refreshing to have someone pause, listen, explain, and offer valuable advice.
Highly recommend working with Dan & his team. Very thoughtful, efficient and explains the process thoroughly. We had our attic sealed for air leaks with new insulation as ours created dust all over. He also installed a new exhaust fan. I am officially looking forward to winter (haha) to see all the benefits! Thank you so much for your help & support!

Had Profoamers insulate ½ of basement’s upper box sills with closed cell spray insulation. I was able to handle everything on-line providing the job’s measurements and receiving back a quote. I felt it to be a very fair price. Insulators arrived on time, in fact early. Their truck was very clean and with all the equipment extremely organized. While showing them the scope of the project they stopped me often to ask detailed questions of my exact wishes of how I wanted each portion applied. The process did not take long and upon my inspection, I was pleased to notice everything was cleaned and the floors were swept spotless. It was evident they were pros at doing this and were very proud of the completed job. I would certainly call them in the future and recommend them to anybody that asks me.
Pro-Formers did a great job on my projected. They showed up early and finished on time. Nice job cleaning up after the job was done. I had not sealed some area like I should have, which resulted in some over spray. They kept a positive attitude and cleaned up my miss. Great team of guys. I will use them again.
Pro-Foamers is a great company! They did an amazing job on my basement! Sealed the outside concrete, spray foamed the basement walls inside. Kelly’s recommendations are spot on! They did the work very fast and cleaned up everything when finished. Would highly recommend them. Thank you Pro-Foamers!!

Great company. Pleasure to do business with.
Came next day after I called and Mike had an estimate to me in two days. The foam and attic blowing crews were both on time and friendly. They did an excellent job. My house is 100% warmer and more efficient. Thanks!

Delivery Appt time 5am they opened overhead door at 4:30, I backed in, by 4:45 they were already unloading me. Yes I backed down driveway easy enough, and parked overnight to the side so others could get by me. Didn’t mind delivering to this place at all.
Gary provides fast bids and keeps a close eye on schedule! Great Experience Karpathian Properties
TRUCKERS: Don’t pull into lot. Turn left then back down the driveway half way and be sure to stay as far to one side as possible so their work trucks can get through. They had no problem with me parking here overnight. The dock will be the overhead door directly behind you if you backed down the driveway. Super friendly people and they unloaded me an hour before my appointment and I was gone in 20 minutes. My photo is from the vantage point of the dock. That’s the driveway you need to back down.
