Koala Insulation of Mercer & Middlesex Counties

This is a first class outfit. Always polite and on time. I had a small crawl space to insulate and needed R30 so foam was my only real option. Not the best of working conditions since the space was a little tight but the guys got it done just as well. If you need insulation work done I highly recommend them.

Koala personnel were all very professional, excellent communication, all questions & concerns addressed & answered fully. Installers, (Anthony & Tyler) were polite, prompt & perfect! Highly recommend. Thank you Koala! 8-20-25

I had an excellent experience with Koala Insulation from start to finish. Tom came out to give the estimate and took the time to explain everything clearly. Anthony, the manager, kept me updated at every stage of the project and made sure everything went smoothly. Tylor and Raul did the insulation-they were professional, friendly and efficient. The work was completed on time and done with great attention to detail. It’s rare to find such great communication and quality workmanship these days. I highly recommend Koala Insulation.
