How to Choose the Right Insulation
When it comes to insulating your home, you have plenty of options. Consider these factors when choosing the right material for your situation.
R-Value
An insulation product’s R-value refers to how well it prevents the flow of heat into your home. A higher R-value equals greater insulation performance. Because Newark features extreme temperature fluctuations in the winter and the summer, we recommend insulation with a minimum rating of R-38. For attic insulation, we recommend considering an even higher R-value, since these spaces aren’t usually well-ventilated.
Efficiency Level
Choosing efficient insulation materials helps lower your energy costs. Look for insulation materials with high efficiency to save money on heating and cooling your home.
Cost of Installation
Depending on the material, insulation can be costly to install. We'll work with you to find the best material for your home that falls within your desired budget.

We had Koala come out to foam our rim joists, seal known air leaks, foam our attic side knee walls, and bring our attic insulation up to code with blown-in fiberglass and dense packing under crawlboards. The work was solid from the start, and they cleaned up thoroughly after every visit.
Over a year later, a third-party energy audit flagged a few spots that had been missed. I reached out to Koala, and they came out promptly, addressed every issue, and documented the fixes with photos. They were completely receptive to my observations and didn’t push back at all.
What really stood out was working with the new owner, Richard. He had a great attitude, treated both me and his team with respect, and clearly cared about getting it right. Richard was right there in the tight, hard-to-reach spaces himself doing the physical labor alongside his crew, not just overseeing. He even ran another blower door test afterward so we could walk through the house and confirm the deficiencies were actually resolved with comparative thermal imaging.
It’s rare to find an owner this hands-on and a contractor who stands behind their work this well, long after the original job was done. Great experience overall.

Don’t bother calling anyone else for your insulation needs. After going through a long list of unreliable contractors, I can honestly say that Matt and the team at Koala Insulation of Newark are the only ones who truly have their act together. Dealing with other companies was a total nightmare, but this experience was the exact opposite.
I have a 150-year-old house, which presents a lot of unique challenges. Even after the job was finished and paid for, we found a small spot that had been missed because it was obstructed by old materials.
Unlike many contractors who disappear once they have your money, Matt came back out immediately to fix it without any argument or additional charge.
It is rare to find that level of integrity today. The “after-care” is what really matters, and Koala Insulation stands behind their work 100%. If you want the job done right by people who actually care about their reputation, these are the guys to use.

Koala worked me into their schedule at short notice. Their work was professional with great follow up. Everything was left neat and tidy in my attic and crawlspace. I noticed an immediate improvement in the comfort of my house. They also handled all the Energize Delaware rebate paperwork.

Koala Insulation of Newark DE are true professionals. Their experience with insulating an older home is second to none. We had them extract all of the old insulation & installed new throughout the attic space in our daughters home. Owner / operator that has a passion for his business explained what was needed. His Koala insulation team was on time, professional, and experienced with residential air sealing & insulation. 100% will use Koala with future homes

Matt and his team were wonderful to work with. I got insulation for my attic and in the knee walls in my Cape Cod style home. They kept me well informed through the whole job, we’re very professional, and worked with me in my schedule. Highly recommend!

Contacted Koala insulation of Newark for an estimate. Ed came out for an estimate of our insulation needs. He walked through our home with my husband and I. He asked a few very technical questions that I don’t believe basic homeowners would know. Like “are your rim joists insulated?” I advised him that I wasn’t sure what he was talking about. His responses to our basic questions were condescending and what my husband and I both felt like we were being “mansplained” about many questions. While I understand that this is the world he lives in and understands, it was clearly not terminology we understood. The estimate was odd and I walked away several times to give myself a break from his presence. The partner he brought with him was the opposite and very kind but I can’t recall the partners name. We very clearly presented to Ed that we would like our estimate to be broken down so we could select which items we wanted to tackle. We also shared with him that we would be having our bathroom above replaced and would likely do this part of the job separate to avoid and issues with the spray foam being ripped out.
We received the estimate a week later. Although, we weren’t happy with Ed’s demeanor we did feel comfortable with what he was proposing to do. The estimate came as an electronic estimate that only allowed me to select the entire 5k job or decline. I contacted Ed and stated the pieces we were agreeing to complete. Approximately $1000 worth of work. I got a response stating he would send a new estimate with only the items we wanted to take on at this moment. When the new estimate arrived we noticed the estimate was 15% higher than the last quote. I inquired why this was. I was advised that Ed had added a “trip fee.” He claims this fee was bundled in to the other job we didn’t choose to do. Sounds shady, right? So I text him and shared that we did not find it fair to be charged $150 more when this charge was never technically in the first estimate. His response “I understand.” I advised that we were prepared to move forward with the job without the trip fee. About a day later I received a text stating that he couldn’t have added the trip fee to the other estimate. Although everything else in the first estimate was broken down line by line…even the 1 inch foam board and plastic they needed to use. So he absolutely could’ve included that fee…if it was actually being charged in the first estimate. He then sent me a picture of a $995 bottle of spray foam with the text that said “here’s an ad for the product.” Never once did I tell this man that I planned to do the job on my own because we have zero plans to do it on our own. Nor did I ask for the product.
For a company with 5 star reviews, I expected significantly better. Ed was not only condescending throughout but the text he sent was just flat out rude. In addition, my home location is 25 minutes from Newark. Why are they charging $150 to travel to a house? It was 18 miles door to door. Do they charge everyone a $150 fee or did Ed just want to inflate the cost of the job? Either way, I don’t spend my money on businesses who practice like this or who hire employees like Ed.

We have a 60 year old split level that had little to no insulation, we participated in the Delaware home energy audit program and now we have a well insulated 60 year old split level. The improvements to our energy expenses and comfort have been dramatic. Matt and his team's pricing, professionalism and diligence to their work was fantastic. Can't recommend Koala Insulation enough for your home insulation needs.

Koala CARES! I was extremely satisfied with my experience with Koala Insulation of Newark. This team went above and beyond in every aspect of this service. Matt Baxter was extremely helpful and always took the time to explain the process and make me feel comfortable. Matt was looking out for my best interest from the start. He offered options for savings and came out twice during the scope development process to ensure everything would work out great. Matt came out every day of the project as well. He's a first class guy that truly values his customers.
We had a baby on the way when we decided to complete this project. This team supported our needs and schedule! They made it happen and made it happen safely!
Ed deserves a great deal of recognition and thanks. His expertise and general home knowledge was of immense value. He recognized and solved a couple of issues and I couldn't be more thankful!
Stathi also deserves recognition. He did a amazing job removing old and unwanted insulation. He made sure the job was done right!
Reach out to Koala! The air sealing and insulation work they did will save me hundreds a year on heating and cooling.

Awesome company!! Very happy with Koala and the services they provided. The owner Matt was very helpful and explained the process every step of the way. The day of the job his crew arrived on time and was very professional and thorough. We are already noticing the increased comfort in our home and I will be recommending Koala to all of my friends and family.

We hired this company to do air sealing and insulation in our home, using a mixture of spray foam and fiberglass in different spaces. I was impressed with the reduction in air loss they were able to get. They exceeded their own estimates even; I am always pleasantly surprised when a company over-delivers, although we may have also just gotten lucky. I found this company very easy to work with: they communicated clearly and gave us a sense of the relative pros and cons of different options, and what would be most cost-effective. Although I was mainly motivated to hire these guys to save money on my heating bill, I also noticed an immediate improvement in comfort after doing their work. The house was less drafty, the basement became particularly warmer, and this in turn made the first floor's floor warmer which made it much more comfortable.
