Mess stays out of tight spaces: Hauling old insulation through narrow stairs and shared entries spreads dust and allergens, so our exterior vacuum setup keeps it out of your living areas.
Professional Insulation Removal in Newark, NJ
Let Our Insulation Experts Show You The Many Benefits Of Our High Performance Insulation.
In Newark, cold, snowy winters and sticky summers put attic insulation on double duty, and much of the city’s older housing stock was never insulated for today’s energy costs. Once material settles, dampens, or shelters pests, comfort slips and utility bills rise. Professional insulation removal clears the old material so your home can run comfortably and affordably again.

Signs Your Attic Needs Fresh Insulation
In Newark’s older homes, attic insulation often lags behind the weather, and removal is worth considering once you notice:
Cold, uneven rooms and rising heating bills as thin or settled insulation lets warmth escape in winter
Ice dams and attic moisture that leave older insulation damp, matted, or moldy
Knob-and-tube or wiring upgrades in pre-war and mid-century homes that require the insulation cleared first
Mice or squirrels that nest in attics across dense neighborhoods and leave droppings behind
Muggy summer heat that overwhelms compressed insulation and drives up cooling costs
A musty odor or allergy symptoms that point to aging or contaminated material overhead
A Superior
Comfort in Every Season, Lower Bills
How the old insulation leaves your home makes all the difference. We stage our vacuum outside and pull the material straight into a sealed container, so dust, fibers, and debris never travel through your hallways or stairwells. In Newark's tightly built homes and multi-family layouts, that contained method protects the air inside while the attic is cleared.
These capabilities define the insulation type:
Prepared for older material: Decades-old, settled, or pest-fouled insulation calls for commercial vacuums, protective gear, and treatment products to remove it safely and thoroughly.
Protects everyone indoors: Disturbed insulation can release fine particles and old-home dust, so containment and protective equipment matter for every household in the building.
Newark's Easy 5-Step
Insulation Removal Process
Free Home Energy Assessment
Our Koala Insulation specialists look at how your home holds heat through winter and copes with Newark's humid summers, and where energy escapes.
- Home & Attic Walk-ThroughWe start every job with a careful inspection of your attic and home. We check insulation type and depth, look for moisture and ice-dam damage, note any knob-and-tube wiring or pest activity, and assess ventilation and access, so the removal is planned to be safe and clean in an older home.
Koala Difference: We account for the aging wiring, tight framing, and moisture issues common in Newark’s pre-war and mid-century homes.
- Sealing & ContainmentBefore removal begins, we protect your home and its shared spaces. We seal access points, cover the route from the attic to the exit, and set up barriers or negative-air equipment where needed, so dust and debris stay out of your finished rooms and any neighboring units.
Koala Difference: Careful containment matters in dense, multi-family homes, keeping dust out of your space and your neighbors’ units.
- Old Insulation RemovalOur crew removes the aging insulation with professional vacuum equipment, working through the attic and into eaves, corners, and the tight spots common in older homes. Settled, damp, or contaminated material is drawn directly into a sealed unit outside.
Koala Difference: Commercial extraction and containment clear decades-old material without tracking it through your home.
- HEPA Detail Cleaning & Treatment
With the bulk removed, we detail the space. HEPA-filtered vacuums sweep the attic floor and framing to lift the fine dust and old-home debris left behind. If we encountered pests, droppings, or moisture, we can apply a disinfectant or antimicrobial treatment and finish with a deodorizer to clear stale odors.
Koala Difference: HEPA detailing and targeted treatment leave a genuinely clean attic, not just an emptied one.
- Haul-Off & Compliant Disposal
Once the attic is clear, the old insulation is bagged, loaded, and hauled off-site for disposal that follows Essex County and New Jersey environmental rules. Your property is left tidy, and the material is handled responsibly rather than piled at the curb in a crowded neighborhood.
Koala Difference: Responsible haul-away is included, so cleanup and disposal never fall to you.

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 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. 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.

My home is older with knob-and-tube wiring. Does the insulation need to come out?
In many older Newark homes, yes. Insulation packed around active knob-and-tube wiring can be a safety concern, and electricians often need the attic cleared before they can update the system. Beyond wiring, decades-old insulation is frequently settled, dusty, or pest-damaged. We remove it safely with sealed equipment, so the attic is ready for new wiring and modern insulation to go in.
Should I remove the old insulation or just add more on top?
It depends on what is up there. When the existing insulation is dry, intact, and uncontaminated, topping it up toward R-60 can be efficient. In many older homes, though, the material is matted, damp from ice dams, contaminated by pests, or wrapped around outdated wiring, and in those cases removal is the sounder choice. A free assessment tells you clearly which approach your home calls for.
Can you remove insulation in a multi-family or rental property?
Absolutely. We work in single-family homes, row homes, and multi-family and rental buildings throughout Newark and Essex County. Our sealed, outside-staged equipment and careful containment are especially valuable in shared buildings, keeping dust and debris out of neighboring units. We coordinate access with owners or managers and haul all the old material away for proper disposal when the work is done.
