Spray Foam Insulation Installation
Koala did an amazing job with our attic insulation. Their team was very knowledgeable and Brian was very helpful throughout the entire process. We had a few other companies quote the job but ultimately went with Koala due to their expertise and plan of attack for the insulation. Brian sat down with us before the job to see what our needs were and even helped us with the entire rebate process after. The day of insulating, their team was very personable, quick, and high quality. Prior to the insulation, our house would feel 10 degrees different from the downstairs to the upstairs in the summertime. Now, the difference in my house, especially in these hotter months, is clear. Our house is much more comfortable than it was a year ago. I would highly recommend Koala!

Spray Foam Insulation Installation
I was extremely impressed with the work from Koala insulation. I live in an older house and was having major energy drain issues and my house has always been cold. After the insulation, I could immediately feel the difference, and for the first time, I didn’t need to keep the heat pump running 24x7 to keep the temperature. I can wait to see the savings as I think this is going to cut my bills by a large amount.

Very professional company. From the initial contact, inspection and quote by Brian, to prompt scheduling follow-up by Jessen and arrival of the team, everything went seamlessly. Would definitely recommend this company. Jabari and Anthony did a great job insulating the rim joists, adding wall and pipe insulation under the sink on an outside wall and caulking a leaky window - no more breezes. Definitely feel a difference in the house now. The added attic hatch cover makes the heat stay below, where it belongs. Really appreciated the use of PPE when they were working with mineral wool. Very satisfied customer here.

"Lynn, thanks so much for this kind review. Again, similar to Juan above you, professional was a key word that you used. That's very satisfying for me to see as that's something that we drum into our teams...we're trying to be different to other contractors."

I had some insulation issues in my home over the early winter months. I reached out to a few companies; some who never got back to me. Brian at Koala reached out, made an appointment soon after contact, and provided a very knowledgeable evaluation of my issues. His team came out and did great work and even cleaned up after. Great communication. And even went the extra mile to stay on me about getting the necessary documents to make sure I took advantage of rebates that I qualified for. A++ from me.

Brian and his crew are phenomenal. Their attention to detail is unmatched. My house is mildly unorthodox and Brian and I had many conversations about the right approach and solution as far as energy efficiency, and accomplishing the job with complete care to maintain irreplaceable features of the house. I never felt pushed or pressured, and truly felt like Brian treated my house like he would his own. Special thanks to Jessen and the crew for their continued attention to detail!! Very helpful and informative. Completely down to earth, strait forward, honest guys. 10/10. Really can’t recommend these guys enough!!

Entire process was seamless from beginning to end. I was able to secure an appointment for inspection and estimate quickly which was a huge help. The site crew was prompt, professional, and left no trace of work left over. Great company to work with; professional, dependable, prompt and fair. So glad I found them. They did not disappoint!

You cant go wrong. Anything you ask is shown and proven to you. Brian has a true gift of working with people, not to get the job, but to make you feel that you have the knowledge to make your decision weather it's with him or someone else. Tech on the job was great and friendly. Explaining other uses and jobs they have done. Thier equipment was state of the art ,well maintained and clean, unlike a fly by night co. If you need a job done ,you owe it to yourself to give him a call and learn more about what you are having done. Oh and don't be surprised if YOU find yourself writing a review for them.

"Robert, thanks for the great review. I am pleased that your brother-in-law is more comfortable and I know his bills will be lower. It's been a tough winter so I am sure he's the envy of the neighborhood."
