They were very easy to work with. Arrived on time for appointments, quick and easy to schedule. The salesperson was honest and didn't try to oversell. The installer was prompt and very efficient, in and out in under 90 minutes for a rim joist insulation in the crawlspace. I would definitely recommend them to anyone and will use again if needed.

The project started 4 days after they gave us a quote, and the price was below asking from the other companies. The crew called 15min when they were en route. They finished within the time they mentioned, I highly recommend this company. Friendly team!!!

They were incredibly detail oriented and went above and beyond and repaired multiple air vents that were previously damaged. After the install, they went through my entire house to vacuum to make sure it was spotless by the time they left. I HIGHLY recommend them. They were on time, efficient, and did a great job. Cannot say enough good things about my experience.

Nick & the other two installers were very polite, friendly & respectful. Nick even took a picture of our new attic exhaust fan so we could see the work they did. My new exhaust fan is whisper quiet too.

My Upstairs are Cool Again! The Koala Crew is very professional. They bring in their own blankets/carpets to place on your floors and steps so they do not dirty your house. The process of installing more installation went much faster than I thought it would. They cleaned up after themselves. Then within a few hours after they left with the help of my AC, the upstairs no longer felt humid. It was awesome. I knew we made the right decision to go with Koala.

The project went as planned. Nick and his crew finished the job within the time frame provided. Cleaned up after themselves not leaving any insulation on the floor or anywhere. They made sure to check that everything was to satisfaction.

The sales manager, Gary, recognized what our insulation needs were and submitted a quote which we accepted. Gary was able to schedule the job for the very next week. Nick & John, the installers, were absolutely wonderful---very professional, thorough and great workers. Koala gets an A++++. We strongly recommend Koala Insulation. Fred & Cindy B.
