Easiest people I have ever worked with. They laid everything out to me and let me decide what I wanted to do. No pressure. From the time I called for an estimate to the time the job was done was less than 3 weeks. Highly recommend Koala Insulation!! Very happy with the results.
Had multiple insulation issues. From the sales consultant, Austin Olsen, to the insulation team, options were given, pricing was clear & everything was very professional. Brian Aho & Jaxon Logan were polite, careful of walls, laid down carpet protection, etc. They left a card in case there were any follow up questions. Very pleased.
Would highly recommend Koala Insulation of the Fox Valley. Brian the owner provided us with a detailed quote to remove areas of old (historic chalky black) insulation, bring in new insulation to bring our attic to code, etc., and installation of solar vents. On the day of the installation Jaxon and Logan provided excellent installation services along with Brian.

Responsive, professional, knowledge, efficient, and reasonably priced. I had Bart's add additional insulation to our attic to bring it up to the current standards, and a few other companies give me a quote on the job. I went with Bart's, and I have no regrets!
Bart's Insulation was very professional, prompt, and reasonably priced. I was also impressed that the owner of the company was actually the one blowing in our attic insulation. Would definitely recommend.
Very affordable and a professional experience with the employees.

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.

Tom is very thorough and down to earth. He came out, inspected and gave an estimate within a couple days of calling. The estimate was given on a Friday and by Monday afternoon he was here to do the job. The house was cleaned up perfectly afterwards. This company is top notch in my opinion! If you want a knowledgeable man at a very affordable rate look no farther.
Worked with Tom on adding insulation to my attic. Awesome guy to work with, provided excellent service and knowledge and did an amazing job! My A/C unit no longer runs 24/7 and it is 100x more quiet inside my home. Great price, great work, and great people. Definitely go with these guys if you need some insulation work!
I recently had the pleasure of working with Tom from Lakeshore Insulators, and I can't recommend him highly enough! From the moment he arrived, Tom was professional, knowledgeable, and genuinely passionate about his work. He took the time to explain the insulation process and answered all my questions with patience and clarity. The quality of his work was outstanding. Tom was meticulous in his approach, ensuring that every detail was perfect. I noticed an immediate difference in the comfort of my home after the insulation was installed. Not only did he do an excellent job, but he also completed the project on time and within budget. What truly sets Tom apart is his commitment to customer satisfaction. He went above and beyond to ensure I was happy with the results, and his friendly demeanor made the entire experience enjoyable. If you're looking for reliable and high-quality insulation services, look no further than Tom at Lakeshore Insulators. He’s a true professional and a pleasure to work with!

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!

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.
