Just had David and his team do blown-in in our house and the service and install was the best. They were neat clean and right away notice a huge difference in our electric bill along with overhead noise from outside from airplanes....so happy with this investment to our home!

The Koala crew did a great job. The insulation job was promptly scheduled and reasonably priced. The additional insulation should reduce my electric bill. My house needed missing insulation to be reinstalled. Jeff, and the crew were professional and super nice to deal with. Thank you so very much.

Great experience! Connor showed up on time for our consultation and he was extremely personable and real knowledgeable about all of the different insulation solutions Koala has available. I thought I would drive him crazy with all my questions, but he was patient and was able to give answers that really made sense. I decided on the spray foam, and I could not be happier with the results. I feel like I live inside a giant Yeti cooler now! I expected the foam to make a difference, but I had no idea just how effective it could be. On top of controlling the temperature, the house is a lot quieter now, which I hadn't considered when I decided to go this route. Don't hesitate to have Connor and his team out to your place. My only regret is not making this decision sooner. Thanks so much guys!

LEARN ABOUT air sealing!

One of the best ways to get the biggest return on your air sealing investment is to combine it with an insulation upgrade! Learn more about types of insulation that we use in our videos below!

Why air sealing is important

Insulation alone is not going to be as effective as with combining it with air sealing. To deliver the optimal improved energy efficiency, air sealing will act as a vapor barrier and stop any air from penetrating into your home.

By sealing all gaps and holes, it creates an air barrier, blocking air from passing through walls and the ceiling into the attic or outside air in filtrating into your home.

A properly sealed home will not only stop air leakage but will also keep water out, keeping your insulation in top condition. It also contributes to increased comfort, improved indoor quality, lower utility bills and controls moisture.

Koala insulation experts offer custom solutions to provide you with the right solutions for your specific needs. We offer air sealing services along with batt, spray foam and blown-in insulation products to guard against heat loss and moisture related problems.

CELLULOSE

Cellulose consists of fibers made from recycled newspaper, cardboard, or wood and is made with or without binders. Cellulose is a very common type of blown-in insulation as it is made from recycled materials and is chemically treated to resist pests, mold, and fire. Boric acid is the primary chemical used to treat Cellulose insulation and is found naturally in seawater, fruits, and plants.

FIBERGLASS

Fiberglass is made from plastic, glass, and other raw materials that are melted and spun into fibers that resemble the texture of wool. Fiberglass insulation has moisture and fire-resistant properties. Because fiberglass is made from sand and glass, it is naturally non-combustible. Fiberglass has significant recycled content with some loose-fill products containing up to 80% recycled glass.

I'm happy to recommend Koala Insulation of Denver Central, Greg, and his awesome team!

Greg with Koala was prompt in responding to our request for a bid. He was right on time, and as an extremely busy professional that matters to me. The quote was fair, itemized, easy to understand, and convenient as it came via email and text. Greg is a professional and it showed.

We sought other estimates and the range of responsiveness was nothing like Greg and Koala - some competitors still haven't returned our calls!

Once we decided to move forward with Koala, Greg phoned and provided a number of scheduling options to fit our schedule.

Jose, Junior, and Eduardo showed up as scheduled, were polite, professional, and considerate of our home, and completed the work quickly. They ensured that they protected our flooring and cleaned up afterwards.

I'm happy to recommend Koala Insulation of Denver Central, Greg, and his awesome team!

Aurora

The process went smoothly and the guys doing the work were efficient and friendly

Koala Insulation of Denver Central provided me detailed options for insulating my 93 year old home. Their prices were competitive with other estimates. Greg answered my questions and helped me make the best decision on redoing the insulation in my attic. The process went smoothly and the guys doing the work were efficient and friendly. They showed me pictures and cleaned up everything beautifully. I have referred the company to two other neighbors who have engaged the company to do their insulation. I recommend you give Greg a call to discuss your insulation needs.

He did a great job completing the service and leaving my place spotless when finished

Greg came out to give me my estimate. He was great! He is very knowledgeable, kind and informative. He took the time to explain everything in detail and make sure I understood. Eduardo came out to complete the service. He had great customer service as well and was very friendly. He did a great job completing the service and leaving my place spotless when finished. Would highly recommend.

Aurora

Koala is one of the few gems

Let me start this review by saying I have found only fractions of 1% of contractors that actually care about what they do. Koala is one of the few gems. Eduardo and Tho we're outstanding. Kind, respectful, honest, and actually watched what they were doing. I had hired them to install closed cell spray foam in my basement and could not be happier. The installation was quick and painless. Consistent attention to detail throughout and no shortcuts. Price was also very reasonable for the work involved. I would highly recommend using their services for any insulation project one may have!

Aurora

Would Highly recommend Koala of Denver

Easy communication, affordable options. Greg will work with you in finding the better solution for your insulation needs and will answer your questions promptly as they arise. Greg was quick to offer an alternate sound absorbing solution when the crew found out, on site, the space behind the panel that served as a "wall" would not allow for blow in cellulose. The holes in the walls were patched up with care. Would highly recommend Koala of Denver!

Denver

I cannot recommend them more highly

If I could give these folks more than 5 stars, I would! Greg and his team were nothing but professional, helpful, friendly and knowledgeable throughout the entire process, from the estimate to the completion of the project. They communicated with me continously, even letting me know when they would be a little late due to road conditions. I've had my share of contractors who just didn't show up or just showed up without letting me know they were coming, so the accurate and timely communication is greatly appreciated. The Koala team also did an excellent job of cleaning up at the end of each day. I cannot recommend them more highly.

Aurora

Very happy with the results

Great work. Greg quickly scheduled someone to help insulate my kitchen during a remodel. They arrived on time, diligently prepped the area, and sprayed the foam in just a few hours. Very happy with the results."

Denver

I had the best experience with Koala Insulation

I had the best experience with Koala Insulation. From start to finish they were very professional and did a great job explained everything very thoroughly although they were not the least expensive of estimates I received they certainly were the best. I highly recommend them. They did a perfect job cleaning up also. I'm already noticing a difference in the furnace not coming on as much as well as fewer cold spots in the house. Great job guys.

Blower Door Test

Thank you for the professional work!! Greg, the owner has a great crew, including Eduardo who can fit into tight spaces!
Greg set up the Blower test and walked all three floors to identify what areas need caulking, and other fixes.
The spray foam sealed up exterial wall joists.

Money well spent for a job so well done!

Greg Cooper from Koala contacted me immediately when I found him on Anji. He was very patient with me and my schedule as I figured out my time line. When I was finally prepared to show the project, Greg was punctual to the minute when he arrived to give me pricing. He was able to measure square footage, give me 3 options to work with in terms of building codes from when permit was pulled, IBC and current codes. (I have been doing my own renovations for over 10 years, so codes have changed since I started.)

Greg was straight forward and never once put pressure on me or tried to “up sale” the higher bid for most efficiency which in the end was my preference. He was also decent enough to tell me that if I decided to work with someone else, he appreciated that I contacted him regardless. He allowed me time to get my ducks in a row. His communication was respectful and always swift. I called a couple of other contractors who also seemed good, but I liked Greg, Koala and their pricing the best.

My home is over 100 years old. The newer second story addition is now not only snug as a bug, but much quieter. (I live on a loud busy street.)
I can finally feel a difference in efficiency when I go upstairs. I believe I can easily keep it comfortable temperature wise with the minimal existing duct work in place. (I won’t know until we get a hard cold snap, bur so far it’s an amazing improvement.)

Finally, the 2 man crew were of same high caliber. Punctual, Respectful, Hard Working, Efficient and On Schedule. I have only good things to say and feel confident in my recommendation for Koala Insulation of Denver. Like it should be… Money well spent for a job so well done!
