Spray foam creates a rigid, airtight seal that eliminates drafts, blocks moisture, and provides structural reinforcement to your property.

Our consistent service and commitment to efficiency have built our reputation as a top Newark spray foam insulation contractor.
A Superior
Thermal & Air Barrier Services in Newark
Spray foam systems offer Newark homeowners and businesses a range of performance benefits. Spray foam products serve as an effective thermal barrier, just like traditional insulation materials, while offering additional advantages.
These capabilities define the insulation type:
Blocks Air Infiltration: The insulation system prevents treated air from transferring through gaps, holes, or damage in exterior walls and roofs.
Stops Moisture: Spray foam blocks moisture from entering the treated space and contributing to heat loss or gain.
Advantages Of
Spray Foam Insulation in Newark
Spray foam insulation outperforms all other types of insulation by large margins because its long-term benefits outweigh its initial installation costs. Spray foam also offers superior sealing properties and is environmentally friendly.
Improved Air Quality
Proper insulation is crucial for protecting your Newark home from dust, allergens, and urban pollutants. Choosing spray foam insulation significantly improves indoor air quality by sealing drafts and controlling moisture levels, creating a healthier living space while boosting energy efficiency across New Jersey’s changing seasons.
Water & Fire Resistance
Spray foam insulation is a vital solution for Newark homes, providing a robust barrier against moisture and enhancing fire safety. Its mildew-resistant properties offer essential protection against New Jersey’s humidity and water damage, while its fire-rated performance ensures a safer, more resilient environment for your property.
Pest and Wildlife Protection
Spray foam insulation provides an effective barrier against pests like insects and rodents common in Newark. Its seamless application creates an airtight seal that significantly reduces the chances of these unwanted visitors entering your home, delivering long-lasting protection and added peace of mind for New Jersey residents.
Strengthens Buildings
Spray foam insulation provides more than just a thermal seal; it significantly reinforces the structural integrity of your Newark property. Once professionally installed and cured, the foam creates a high-density bond with framing, sheathing, and interior surfaces, helping buildings better withstand the vibrations and settling common in urban New Jersey environments. This added rigidity minimizes wall flex and enhances soundproofing, ensuring a quieter, more durable, and energy-efficient home for years to come.
Soundproofing
By sealing gaps and cracks, spray foam creates a continuous barrier within Newark homes to significantly reduce unwanted noise. Its dense structure absorbs and dampens sound waves, effectively muting urban outdoor noise and disruptions from HVAC systems or plumbing lines to create a more peaceful living environment.
Environmentally Friendly
Choosing spray foam insulation is a sustainable way for Newark homeowners to create a more energy-efficient, resilient environment. Unlike traditional materials that may shed fibers, cured spray foam is chemically inert, meaning it doesn’t release harmful particles into your living space or contribute to urban air pollution. During our professional installation process, specialized equipment ensures a precise application tailored to New Jersey’s building codes. While a brief off-gassing period is standard, once cured, the foam provides a permanent, seamless air seal that significantly reduces the carbon footprint of your property. Because closed-cell varieties do not retain moisture or support mold growth, they act as a robust secondary barrier against the humid Atlantic climate, preserving your home’s structural integrity for decades.

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

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 00 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 0 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 5 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 0 to travel to a house? It was 18 miles door to door. Do they charge everyone a 0 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.

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.

Is spray foam right for my attic in Newark?
Spray foam insulation can be an excellent choice for attics, but there are a few key factors to consider:
Moisture and Preparation: Any existing dampness or water intrusion should be resolved before installation to ensure strong adhesion and long-term performance.
Surface Readiness: Concrete or masonry walls may need light cleaning or preparation so the foam bonds evenly and seals effectively.
By addressing these factors, spray foam creates a dry, comfortable, and energy-efficient environment that helps protect your home from the ground up. When applied by certified Koala Insulation professionals, spray foam provides lasting comfort, reduced energy costs, and year-round peace of mind. Learn More

Should I insulate my basement ceiling with spray foam?
Closed-cell spray foam works best for basement ceilings because it provides a high R-value and acts as a moisture barrier. It can also help block sound between floors. For the best results, it’s important to assess your home’s layout, HVAC design, and moisture conditions before choosing where to apply spray foam.
Koala Insulation technicians can evaluate your space and recommend whether ceiling, wall, or rim-joist insulation will deliver the greatest comfort and energy savings for your home.
Is spray foam insulation safe?
Spray foam insulation is safe when handled and installed by a trained professional. Spray foam poses no health risk once it is cured, but it can be hazardous during installation due to its chemical composition. We follow all industry safety standards, ensure proper ventilation, and complete curing before occupants return to the space, usually 24-48 hours after project completion.

Can you insulate the concrete block walls in my basement?
Concrete block basement walls can be insulated with spray foam, provided the surface is clean, dry, and free of moisture issues. Closed-cell spray foam is typically best, as it both insulates and creates a moisture-resistant air seal that helps prevent mold and drafts. Before application, any existing leaks or dampness should be addressed to ensure long-term performance and adhesion.
At Koala Insulation, we’ll determine whether spray foam, rigid foam board, or a hybrid system is the best fit for your block-wall basement so you get a solution built for long-term performance.
Do My Rim Joists Need An Airtight Seal?
Rim joists absolutely benefit from an airtight seal. Sealing this area with spray foam insulation prevents drafts, moisture intrusion, and heat loss where the foundation meets the framing, one of the most common sources of energy waste in a home. By creating a continuous air barrier, you’ll enjoy warmer floors, lower utility bills, and better indoor air quality year-round.

Is spray foam insulation flammable?
Spray foam insulation itself is not flammable once fully cured, but like most building materials, it can burn when exposed to direct flame. Koala Insulation uses fire-rated, code-compliant products. When installed correctly by our certified technicians, spray foam insulation provides a safe, durable, and energy-efficient layer that meets modern fire safety standards.

When installed correctly by our certified technicians, spray foam insulation provides a safe, durable, and energy-efficient layer that meets modern fire safety standards.
How long does spray foam insulation last?
Spray foam insulation typically lasts 80 to 100 years when professionally installed and properly maintained. Spray foam adheres directly to the building structure and won’t sag or settle, which means it offers the same performance decade after decade.
What are the best applications for spray foam insulation?
Spray foam insulation is a premium, versatile option for a few specific applications. After your initial assessment, we may recommend spray foam for:
Attics: Open-cell spray foam on attic floors seals air leaks and prevents treated air in the living space from escaping into the attic.
Basements: Closed-cell spray foam acts as a vapor barrier in moisture-prone basements, crawl spaces, and cellars.
Exterior Walls: While not always necessarily the most cost-effective option, spray foam fills irregular gaps in wall cavities while providing an effective moisture barrier.
Floors: Spray foam is sometimes sprayed between floor joists in suspended timber floors (non-slab).
Roofs: Closed-cell spray foam installed under the roof deck prevents air leaks and protects against moisture issues.
Can I spray foam insulation myself?
While DIY kits exist, spray foam insulation is not a good do-it-yourself project. Professional installers have the training, equipment, and ventilation controls needed to ensure safety, proper curing, and compliance with building codes. Poor installation from DIY attempts can lead to moisture problems, off-ratio foam, or even voided home insurance coverage, making professional service from Koala Insulation technicians the smarter, safer choice.
