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!

Lisa L.

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.

Sarah J.

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.

Honesty

Honesty. I had them come out to take a look at my existing insulation as a new home buyer. Instead of taking advantage of the situation, Charlie was honest and told me areas where I did not even to improve my existing insulation. I feel that honesty is the most important quality when looking for contract, work, and koala insulation has sold me on their business. Will be utilizing them now for some smaller work and then again for my big work in the future.

Very Professional Company

Very professional company.
From the initial visit/inspection to the final job completed, Koal kept me updated at all times. I had blown insulation added to my existing insulation, bringing the level to R49 level.
Pricing was very fair, and the quality of the job was excellent."

I highly recommend Koala for your insulation needs.

Dallas

Highly Recommend

Had a 30' x 60' metal building fully insulated (walls and roof) with 2" closed cell foam. The Koala team was very profession and prompt. It took 3 days to prep, spray, and clean up. There were a couple spots on the roof where the spray did not properly adhere to the metal and started to sag. The Koala team, without hesitation, removed the foam from those areas and resprayed. They ensured the job was done right and to my satisfaction. I would most definitely hire Koala for any future spray foam needs and highly recommend you consider Koala for yours.

Had to increase my thermostat 2 degrees

Koala service was to remove 30 year old insulation and replace with new r-19 insulation.
arrived on time. explained what services i requested and that the service team would perform the insulation on day 1 and return to blow r-19 insulation on day 2.
cleaned up my garage after day 1 and 2 to my satisfaction. service tech found ac connection inoperative and fixed it at no charge. i actually had to increase my thermostat 2 degress due to cold temp in house. great jo Koala!
service team is to be commended because they worked as a team and kept me updated on their progress to my satisfaction. needles to say that i feel the team was very professional and just did an outstanding job on my house. i highly recommend Koala to everyone

Garland

Completely Satisfied

We used Koala to remove all our original insulation, and to install/blow new
Insulation. After several hard days sucking all the old out, we found that we had roof repairs needed and a rodent problem. So we delayed the new insulation for a few months while we worked with contractors to get the problems resolved.

Finally we were ready for the new insulation, and Koala finished the job. They were extremely professional during delays that were not their responsibility. Everyone at Koala were kind, and focused on our happiness. We are completely satisfied with Koala, and highly recommend using them for your insulation needs.

Dallas

From the first phone inquiry

From the first phone inquiry, through the on site estimate and then the blown insulation and finally the solar attic fan….the service was great and the people were all outstanding and thorough. I would recommend this company in a heartbeat….thank you!
Additional they saw an area on our roof (and took photos) where it may need attention by a roofer. Again, thank you!!

Plano

Recommend Heartily

I seldom leave reviews but, in this instance, feel as though it is appropriate. When we hire contractors, we have a universal assumption that the contractor will provide their service or products at a level that demonstrates a love for neighbor. That is, there exists a duty beyond the contractual terms. When the entity meets that duty then it is as it should be.

However, the true test of a friend or a service/product provider is when things do not go as planned. This is when we see the true character of people and companies. Too often, when we make mistakes (we all do), we can resort to denying responsibility, cite fine print that disclaims any moral duty, make counter accusations or any other human weakness.

It is in this test that one is truly measured, and it is in this context that I am bound by my conscious to recommend heartily to all who read this review Koala Insulation. Were mistakes made, yes. Did they fix them above and beyond the call of duty - yes.

We all fail and therefore we should all be merciful as we all need it. The key is that if we are the ones who failed it is how we work to make it right. Charlie and his team did that, for that we are grateful.

The blessing comes most often not when things go perfectly but instead when they do not. It is at that time, that friends are made. I heartily recommend this Firm and pray for their continued success as this is exactly how the world should work.

If you have any doubt between Koala and another provider, please choose Koala.

Great Company with Great People

Charlie came out and inspected our attic. Then he presented a couple of options to us while explaining everything in detail. I told him that we needed to talk it over and make a decision. No pressure from Charlie at all -- he said to take our time. We got back to him later that day and were able to get the work scheduled for the following week. The guys came out on schedule and got it taken care of -- great crew that did very good work. They cleaned up after they were finished and explained what they had done. I would not hesitate to recommend them -- great company with great people.

Absolutely love working with this company

You will absolutely love working with this company. Everyone was very professional from the time Charlie came out to look at what our house needed to when the others came to actually install the insulation. Everyone was well-mannered and made sure the job was done right. They even took extra time to clean up the insulation that had blown around. They really took a lot of time doing this and were meticulous about doing so. You do not find anyone who cleans up this well. So happy to have found them. I would not hesitate to use them.
