Was promised a quote Friday or Saturday. Called Monday and was told I would receive one within an hour. No call or quote. Waited until Wednesday called again. Excuse was the crew had a problem with a different job. Finally got the quote and it had a fan on the quote that was never discussed. Poor customer service. So disappointing.
I did receive a follow up email which was very thoughtful which is why I changed my rating. Thank you

Bad luck and setbacks caused delays and issues, but Koala did what it took to get the job done. Thank you

Corey was awesome. He put down insulation to keep our pipes in the attic from freezing overnight again. We are so thankful that Korey was willing to come out and help us on short notice. Thank you, Corey and Koala Insulation.

The koala team came out and insulated my entire upstairs. They were friendly, knowledgeable, and I couldn’t be happier with the results. Thanks guys!

Huge thanks to the team at Koala Insulation, they came out and re-insulated my attic and were incredibly knowledgeable and professional. Definitely give these guys a call with your insulation needs.

The team at Kola Insulation did a fantastic job of insulating my crawl space and re- insulating my attic. The previous homeowner let the insulation in the crawlspace get wet and moldy. They even used insulation that was not to code. The Kola Team cleaned the mold off the floor joists and reinsulated the floor joist with the right insulation that met code. The attic had old insulation and due to leakage from the old roof had become wet and moldy too. Again they cleaned the mold off the rafters and floor joists and re-insulated my attic to code. The crew as courteous and cleaned up after themselves as if no one was in my house. I highly recommend Koala Insulation to you if you are looking to hire a reliable, professional and fairly priced insulation company!

Will not elaborate at this time due to pending results from court hearing. All you need to know is that i've had to take it THAT far. It should tell you everything you need to know about this company. I saw nothing but great reviews about them, so i decided to go with them to have my metal building spray foamed. I quickly found out the real Koala Insulation of Twin City. Terrible workmanship with only 1 intention....to collect your money and get out soon as they can. They obviously do not know what they're doing. There are several other companies in the area. Go elsewhere before it's too late!

I had two projects performed by Koala. A 745 square foot attic that was sprayed with open cell foam followed by air sealing and loose fill insulation. They performed an excellent job and cleaned up after each job. I'm very satisfied with both the workmanship and cost associated with these projects. I highly recommend them to perform your next insulation job.

The crew knew their stuff when it came to insulation types, and they were super friendly and easy to talk to. Even though the job ended up taking 3 days instead of the estimated 2, it was clear they wanted to do it right rather than rush through. They made sure everything was covered up to avoid any mess. Clean-up was top-notch, and I could see they did a quality job. Already feeling the difference with the new insulation!

I was having a difficult time with my contractor getting someone to finish my house for final inspection. Koala was very professional and did a great job on finishing up my blow in insulation and installing my vapor barrier. I thank them for being prompt and helping me get to my final inspection of my new home. Thank you

Fantastic service. TC was great and thoroughly explained everything that was going to be done. Price was very reasonable and quality of work was top notch.

Koala added insulation board and blow-in insulation around and above the upstairs living space in my house. Erik's estimate was reasonable, spot on (no surprises), and he took the time to present a couple of options with different pricing for me to choose from. The work itself was completed in one day as promised, and was done extremely well. Working with insulation can be extremely messy, but the Koala crew did such a good job with cleanup that there was no trace of them having been in my house when they left. Outstanding!!

The only place you should go!

It's very easy to come in and jack the rates, it's harder to be honest and just help.

In the realm of home improvement, where hammers sing and wrenches waltz, resided this said of a man, the insulation maestro. No mere installer, he is an artist of thermal efficiency, a sculptor of snugness, a bard of BTUs.

He possessed a brain that could outmaneuver a heat leak and taught me more than I even thought I could know. He was so good that I actually was able to go and check my grandmother in law’s and have some idea of how to do it and what to do!

But he was not just  a walking R-value encyclopedia. He possessed the soul of a teacher, patiently explaining the science behind his craft to wide-eyed homeowners. He could weave tales of heat gain and loss, regaling them with cautionary anecdotes of poorly insulated attics and drafty basements. He instilled in them a newfound appreciation for the invisible symphony of temperature regulation playing out within their walls.

So, the next time you find yourself battling the tyranny of drafts or shivering in the face of a plummeting thermostat, remember Koala the insulation impresario. He's more than just a guy who rolls out fiberglass – he's a thermal Jedi, an efficiency evangelist, a conductor of cozy contentment. And in the grand saga of home improvement, he's a character you won't soon forget.

Thank you for not just taking all my money, and leaving me guessing. As that old saying goes whenyou feed a man fish it's great, but when you teach him to fish, it's better, and now I know how to do some thermal fishing.

Everyone with Koala was very professional. There was an unfortunate accident. However, the staff addressed it quickly and to my satisfaction.

Did great work at a reasonable cost. Crew was very friendly, cleaned up behind themselves and worked hard. Highly recommend.

The folks at Koala Insulation are the up most professional. From the initial phone call back to the crew that was sent to perform the Spray foam installation. Considering the tight working space , they managed to place the foam insulation to the full 3" thick agreement.
Actually, they are returning this fall to ad more blown in cellulose to our attic flat. I would highly recommend them for any of your energy home needs.

They installed insulation in my semi finished attic. They cleaned up after and you would have never known they were here except the enjoyment of better insulation for keeping the cool air in during the summer and warm air during the winter! Great job!!! Highly recommend!

Koala was awesome. Will definitely use again for an upcoming project. They were prompt and professional and on time. Did an excellent job.

Steven, Oscar and Enrico completed my attic insulation for a bonus room over the garage. Even though it was an extremely hot day; with the attic temperature well over 100, Steven and his team arrived on time and completed their work (passing inspection) with a great attitude the entire day. Thanks again for a great customer experience.

No nonsense estimate by Eric. Did not try to sell me something I did not need. Very reasonable cost. Speedy scheduling and excellent communication via text and email. Crew was very professional and courteous. Installation was straightforward and we can already feel a difference, especially in our porch that lacked insulation altogether.

Insulation was a great price and the on-site guys were professional and worked quickly. Communication from the office could have been better. I definitely reccomend.

Koala Insulation of Twin City insulated my upstairs that I'm finishing in and did a fantastic job. Their prices was fair and they're very professional. Communication was top notch too. With most other contractors, you're lucky to get anyone to answer or call you back. They came out on time exactly as promised and when they left, they left everything nice and clean. I highly recommend them.

My realtor recommended Koala and it’s owner, Justin Sherrill, to me when I asked who he would call to install insulation in a home. Justin was great to work with. The final cost was the same as his estimate. His crew was on time, respectful and efficient. They did good work and cleaned up after themselves. I highly recommend these folks and would use them again.

Justin and the entire Koala team are exceptional. It was evident from the first meeting they care about customer service and meeting/exceeding the customers' expectations. The insulation team that came out to make the plan a reality, genuinely cared about doing an incredible job, took the time to explain everything and their level of ownership and pride was evident. Highly recommend !!

Justin and his team from Koala Insulation were really great to work with. He was very prompt in providing an onsite visit and providing the estimate to add insulation in the attic area over our garage bonus room. The Koala Team was very prompt, professional, and efficient in completing the job. They were very easy to work with and left the upstairs work area very clean. We were very pleased in the work they did and would highly recommend them. We are hoping to work with them on future projects.

Such a great group of guys - fast, clean and efficient! Justin knows his product thoroughly and confident with his work! I highly recommend Koala Insulation of the Twin City…

Justin and his team from Koala were wonderful!

I appreciated his attention to detail, and the thoughtful and deliberate time taken to resolving my slightly complicated attic situation, and the care taken to ensure I knew exactly what to expect. Justin was very quick to return the estimate and was very quick to get the work scheduled. I want to especially shout out how clean and neat Justin's team left my front yard, the rooms they had to bring their supplies through, and the attic area itself.

I really enjoyed working with this company and I would (and have!) highly recommend them to others considering insulating their attics.

I immediately felt comfortable talking with Justin about accessing our need for additional insulation in our older home. His ability to determine what was needed with a professional electronic estimate before leaving was ideal. The team that did the work knew what to do and were very efficient. I couldn’t be more please with the work they did and the timelessness of all communications. We already notice a difference in how our house feels with the added insulation. Great experience!

Excellent work for a great price. The guys showed up on time and finished their work without delay. The only drawback; I wish they had warned me about the dust but I suppose I should have known.!. Will recommend them to anyone.
Can't wait to see the difference in heating cost.

Justin and his crew did an excellent job of insulating our attic and knee-wall space. They were punctual, friendly, efficient and professional, and I highly recommend them.

Attic insulation install: I removed old furniture etc from the attic myself before the install. Workers arrived on time the first day & removed fiberglass batting. Second day was an all day install of the foam. Owner returned three days later by my request to remove metal staples used to secure plastic drop cloth on attic flooring & to vacuum up stray bits of foam on attic flooring. Now using fans to air out attic space & exhaust odor out of the house. Should take about a week of ventilation to clear the odor. I was very impressed with the professional approach used by Koala Insulation and would recommend the company to other home owners in the area.

Koala removed our preexisting insulation as well as installed new. We worked with a few different professionals. They were all very kind and did their jobs well. We would definitely recommend this company.

The team with Koala insulation helped with getting our attic insulation updated and ready for winter. They were efficient, friendly, right on time, and came in at a budget that worked great for my family

This company added insulation to my attic space, covered the whole house fan and installed a “tent “ over the drop down stairs.

Justin and his crew did a great job! Communication was on point and clear throughout the process. Justin was available for questions and to ensure the job was done right. The crew manager consistently updated us with the schedule and work being done. The crew were kind and courteous. Overall, great work on our spray foam!

Courtney Herr

Justin and his team were great to work throughout the entire process! He came out within a day to do an initial evaluation and give a quote. He walked us through several different options, and helped us decide which made the most sense for our space. We were then able to get scheduled right away and couldn't be happier with the work they performed. The team was professional and efficient with the installation, and now we can use our finished attic as actual living space! Would highly recommend for all your insulation needs!

Koala came in on time and put insulation in my new construction. I held them up with putting it in my attic because my siding wasn’t up yet. They were so patient and when I was finally ready , they came out within days. They were very friendly and a lot of fun to work with. I would highly recommend them to anyone. I would most certainly use them again.

Koala worked me into their schedule within a week and they were in and out within a day. Their pricing for foam insulation is very competitive. They are also very professional and responsive to emails.

We interviewed 4 insulation contractors, of all the ones that provided estimates, this one was the most professional and most detailed. Very patient in detailing what was needing and why it was needed. They arrived on time, they were efficient and thorough.

Everything about the insulation project was first rate, particularly the removal of the old insulation that had become, unbeknown to me, completely ineffective and unhealthy. The crew were impeccable; on time; professional; and all together knowledgeable. And they cared for the property inside and outside. I was very impressed and would recommend the company without hesitation.

I’d like to thank Justin and his crew for the excellent job they did at my house ! They installed spray foam around the whole perimeter of my split foyer and also rock wool in the ceiling of the family room downstairs. I can feel the difference already .

Excellent professional service. If you are having insulation put in, shop no further, for this is as good as is gets. Excellent sales and installation personel at a fair price. Very thorough and they neatly protected our items in the basement and cleaned up thoroughly. They even moved several small items out of my garage so they could work. Highly recommend this company. Thanks goes out to the entire Koala team.

Koala Insulation truly made the whole process a 5-star experience. They added important insight in helping me decide which type of insulation to purchase. Their prices were fair, their staff was very polite and respectful. Their work was meticulous, and they were careful to ensure the safety of my family during the installation process.
