Koala Insulation did an outstanding job on my home project. They added R-50 blown insulation to the attic over the garage, sealed the top plate between the garage and living area, and replaced the insulated duct to our master bath fan. The team was professional, efficient, and represented Koala Insulation exceptionally well. They completed everything in under two hours and left the area spotless. Highly recommend Koala Insulation for anyone looking for quality, reliable insulation work!
Everyone did a great job from consultation to install. Matt and John treated my home with respect and actually found a way to cut some cost for me while resolving my issue. If you need any attic/insulation work I would whole heartedly recommend Koala.
First, I’ll start off saying I was looking at reviews koala came up very well. So when I call them young man named Kayden came out and did a very good inspection he came back with his results. The results were a little worse than I was hoped for mainly because there were signs of potential mold starting up there, but he said everything could be handled. give me a detailed list itemized everything out. It’s a pretty good price, but it was a lot of work. I tried to get some other companies to give me an estimate off off of his inspection, but none of them would take that up. So we simply scheduled to work and a gentleman named Ryan and another coworker who I am sorry to say I don’t have his name came out. They were at the house pretty much at the time described little after seven got right to work and absolutely it was an all day job for sure they had to remove every bit of old insulation a sprayed all the wood that was looking black from potential mold. they had to put baffles in everywhere cause there were none and they had to go around and check every eve vent, and every one of them had to be enlarged. Some of that was due to the construction type of the house. I couldn’t be more satisfied with the workmanship with the two men who worked all day, a gentleman by the name of Matt 1 of five with the company I believe also came out. We discussed adding a ceiling exhaust fan in the bathroom which we had never had. We upgraded to a different one which was fine very nice man and Ryan suggested maybe we should call a roofer out. He had a friend that was in the business so we did that and that gentleman showed up another very nice young man with Shamrock roofing the roof is basically OK from the outside of the plywood was getting soft so next roof will have that fixed but overall I think the guys did a top notch job on a job that was probably not the easiest one they come across and I’m very very satisfied with what they did

Our experience with this company was nothing but positive. We were referred to this company when another contractor stood us up. We worked with Chad and he was prompt with responding to our request for a quote to re-insulate our attic and a space in our kitchen that was having issues.We received our quote within a week and the job was scheduled and done within another 2 weeks. The other companies we got quotes from wouldn't even address the issue in our kitchen. The insulators were here when they said they would be and the job was done in the timeframe they promised. Chad came by afterwards and inspected the work. From start to finish he was friendly and informative. We would recommend them to anyone needing insulation work done in a timely manner at a reasonable cost.
We had a great experience with Cornhusker Insulation. Chad was great to work with and was very educational and honest about bringing our insulation level in our attic up to standards. Also, the crew that performed the work was so quick and efficient! Would highly recommend!
Terrible to work with. After the estimate is prepared, you will never see that person again and the crew that shows up, if they show up, will have no background in your project. After two days of no-call, no-show they arrived 4 hours late. They left our house a complete mess and didn’t tell us they were leaving. They apparently don’t carry vacuums or even trash bags with them to clean up their mess. If you loan them one, expect it to be left in the middle of your living space and not carried outside. They even used our tools and never put them back. There are plenty of other insulation companies you should try before you call this one.
