See what our satisfied customers have to say about our insulation removal service!

We called more than a dozen companies for bids to remove and replace our insulation. Koala was the only one who had knowledgeable insight into the job ahead. And offered articulate explanation of different types of products, and a detailed quote for each. No gotchas or surprises....and at an excellent price point. The completed job exceeded my expectations. I don't often give glowing reviews...but these guys absolutely deserve this one. They are highly recommended!

Terry C.

I was interested in having better insulation in my attic. Koala sent a representative to my home and he did a detailed inspection of my attic’s insulation. He sent me three estimates ranging from topping off existing insulation to complete removal of existing insulation and adding new. I thought the pricing was fair. We made our selection and the work was completed to our satisfaction. We’re looking forward to saving in our utility bill. I would recommend Koala for your insulation needs.

Ramiro G.

I have dealt with several contractors for the past 6 weeks and by far Koala insulation was the most pleasant and easy to deal with. They were fully equipped, fully staffed, on time and not a penny over their quote! I would highly recommend.

LEARN ALL ABOUT BLOWN IN INSULATION!

Moisture Damage

Slow, minor leaks, severe weather, excessive or extreme temperatures, and intense humidity will cause moisture to build up. Sealing up air leaks will ensure that the new insulation will not become damp, leading to mold and mildew. Additionally, moisture can cause cellulose to lose its pest and fire-resistant qualities.

Pest Contamination

Rodents, birds, and insects that find their way into your attic, crawlspace, or walls may find your insulation to be quite cozy and thus decide to move in. When removing the old insulation, any pest feces and urine will be removed, and your attic will be sanitized completely before any new insulation get installed.

Air Sealing

Air leakage can lead to the transfer of heat and moisture, which can cause numerous issues, even with the highest insulation level. Reducing air flow is essential to improve the overall energy performance of your home. Koala technicians will seal around your access hatch, recessed lights, duct work and any other spaces that may allow air flow, creating a tight air barrier.

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.

R-Value Matters

When choosing attic insulation, R-value matters. Insulation is labeled by R-value. R stands for resistance to heat flow, the greater the R-value, the higher the insulating power. Koala installers have the knowledge and experience to recommend and install the right density and thickness (R-value).

Fusion-Edit-600 removal

Depending on where you live, different climate zones require different R-values. If you live in a colder climate zone, like the northeast, you’ll need a higher R-value of insulation, then if you live in a milder climate zone. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. Proper batt insulation must be installed higher and over your ceiling joists or wall studs, this allow for optimal insulating.

Koala Insulation Exceeded our Expectations

We became acquainted with Koala Insulation through Jennifer at the 2022 St. Charles Home Show last April. From the initial attic inspection to the day of installation, Jennifer was accessible, professional and very knowledgeable, answering all our questions.

Koala installed a solar attic fan and added blown-in insulation.

Mark, Cory and his crew and Jennifer arrived on time, worked efficiently and, the work area was cleaned up at the end of the project.

With hot weather upon us this early in the year, we’re enjoying a cooler attic which will save us money on our A/C bills. And the added insulation should reduce our heating bills, too.

I would recommend Koala to anyone wanting to lower their energy consumption and their bills; they have several options available.

These Guys Rock!

These guys ROCK! Not only was the estimate for adding insulation to my 58 year old house much lower than I had anticipated, they came out when the temperature broke a record for this day in May (93 degrees) and did an amazing job! Matt paid painstaking attention to the details that were vital (covering attic fan from inside, etc), and he and Corey (sp?) were professional, despite the heat."

2nd time using them....and once again extremely pleased of the work they performed. Wish more contractors had their competence and professionalism. Give them 5 out of 5 no problem.

Customer Review

Excellent service. Blown in insulations for two rooms. A big shout out to Jo for arranging it all so quickly, and to Josh and his mate for showing up on time, working quickly and getting the job done and the great clean up afterwards. It was not an easy job but they were pros and got it done. I have hired a lot of people to work on my homes over the years. I want people who show up when they say they will, quote me a fair price and stick with the price, do the work contracted and clean up after themselves. These folks more than checked the boxes on all accounts. I would highly recommend them

Ballwin, MO

Customer Review

My house is newer, however had hardly any insulation in the garage. They did an awesome job from sealing where there was air leakage and canned light covers. The fiber glass blow in was quick and they cleaned up as if they were never there. I highly recommend this team and look forward to having them do my home attic very soon!

Customer Review

WOW!!! From the free quote, to install, to clean up, these guys are FANTASTIC! In a world full of horror stories on getting work done on your house, these guys are a knight in shining armor. Customer service is very responsive in text, email and phone calls to set up appts etc. We had insulation installed in our finished garage, in the ceiling (there is a bedroom above the garage). I was worried it would be a terrible mess and that it wouldn't work as well as I wanted it to, to regulate temperature. The installers left my garage cleaner than when they came and more importantly that bedroom is now staying within 1-3 degrees of the thermostat (previously a 4-8 degree difference). Highly recommend."

We decided last minute to remove the insulation on our renovation project. Jennifer was absolutely wonderful! She worked it out so they could do the work before we pulled down the ceilings. The crew showed up on time, were very nice, did a great job removing the insulation, and the price was honored based on a sight unseen quote. We highly recommend Koala Insulation.

Review by Orville

Project: Install or Upgrade Blown-In Insulation
Comments: It was smooth from the first contact (owners) the sales rep that gave a thorough description of material products to choose from (what was most suitable for our need and application options. We were impressed and confident enough to sign up for the job, without other quotes. A few days later, a father and son team showed up the job which was completed in about 2.5 hours, including clean up. We didn't bother with seeking other estimates and have no regrets. Orville
