Causes of Poor Insulation
There are three primary reasons for poor insulation. Unfortunately, they're unpreventable even if you take excellent care of your home.
- Age: Living in an older property increases the likelihood of insulation failure. Over time, insulation fibers deteriorate, reducing their efficiency.
- Electrical Stresses: A sudden electrical surge or overvoltage can damage the structural integrity of the insulation.
- Outside Contaminants: Excess moisture, pests, dirt, and other foreign matter can enter insulation through cracks or crevices in the home's structure.
Services Offered
Koala Insulation of Middlesex and Mercer Counties provides comprehensive services for local homeowners.
- Batt Insulation: This instantly recognizable insulation comes in pre-cut rolls and sheets made from organic cotton, mineral wool, or fiberglass. We lay it neatly between studs in attics, floors, and walls, avoiding gaps or compressions.
- Blown-In Insulation: Made from small pieces of cellulose, denim, mineral wool, or fiberglass, Blown-In Insulation fills the cavities of walls, ceilings, and attics, creating a thick and fluffy layer.
- Spray Foam Insulation: Our Spray Foam Insulation is made from spray polyurethane foam (SPF), which we spray against the walls of your home. Its hardening properties create a long-lasting barrier and have the added benefit of noise reduction.
- Insulation Removal: We can remove insulation damaged by contaminants, age, or electrical stresses from ceilings, walls, floors, and attics. After removal, we thoroughly clean and deodorize the area.
- Air Sealing: A high-quality air sealant can eliminate drafty spaces in the home caused by cracks in doorways, window frames, recessed lighting, and other areas.
- Solar Attic Fans: Installing a Solar Attic Fan promotes air circulation, eliminates hot air buildup, and improves attic insulation efficiency. Since it runs on solar energy, it won't increase your monthly utility bills.
- Crawl Space Services: The crawl space can be a source of air leaks. We'll inspect the area for leaks and install the appropriate crawl space insulation.
- Builder Services: We collaborate with local builders on residential, commercial, and industrial insulation projects in the New Brunswick area.

Tyler and Raul did an exceptional job insulating our attic. From the moment they arrived, they were professional, courteous, and incredibly hardworking. Tyler walked me through the entire process, explained everything in detail, and kept me updated with photos throughout the job so I could see exactly what was being done. Their attention to detail and commitment to doing the work the right way gave me complete confidence that the job was in good hands.
What impressed me the most was the pride they took in their work. Not only was the attic insulated perfectly, but they also cleaned up exceptionally well—far beyond just the work area. They left most of the house spotless, which I truly appreciated. Tyler and Raul make a fantastic team, and their honesty, professionalism, and dedication to customer satisfaction really set them apart. I highly recommend them to anyone looking for attic insulation done right.

From the first phone call, the folks at Koala were very courteous and accommodating. I explained that my project was on a very tight timeline, and the scheduler and estimator worked with me to get it done. As for the technicians, Tyler and Raul, they were friendly and knowledgeable. Even though the process wasn't messy, they vacuumed the entire area where they worked.

Tom, Anthony, and the install crew did an excellent job explaining everything and answering all my questions. Installation for the attic fan, air sealing, insulation, and hatch cover was quick and professional. These guys are highly rated for a reason. This is the only insulation company I will use moving forward. I highly recommend Koala insulation.

Anthony and crew where awesome 👏! We had them out to seal, add more insulation & install an attic fan. Anthony explained everything to me in detail. The crew were very neat and professional & the attic looks great! Hopefully it will translate to a much more comfortable upstairs. Thank you 🙏🏼 Kaola !!!

Koala insulated exterior walls in a kitchen and ceiling in the kitchen addition. It was done on time at a very reasonable price. The process was well explained. Work space was well cleaned after work and wall patched well. I really like the result. I would use this company in the future. The crew was very nice 👍

These guys are fantastic. I needed my crawl space and attic insulated badly in my 1940s home. They gave a very detailed estimate with lots of photos, talked through concerns, etc. My service was scheduled during a blizzard, and the crew went above and beyond to make it as easy as humanly possible to get my house up to code. They did spray foam + plastic in the crawl, full air sealing and blown in in the attic. Great experience. Tyler and Anthony communicated promptly every step of the way.

I am extremely hard to please when it comes to construction. Some would call me very demanding.
I was thrilled with the job that the team of four people did at my home today - the foreman, Anthony, to Pete, who sprayed the foam while Raul and Tyler how blew cellulose into the attack. They worked their tails off for eight hours, never stopping for a rest. I was super impressed. Not only did they do good work, but it was obvious that they wanted me be completely satisfied, And they succeeded. Everything was taped off perfectly, so that there was no overspray. It was all done, they cleaned the entire space as though their life depended on it.
I thought the cost of the job was very fair given all they had to do and the way they did it.
I wholeheartedly recommend them.

Great work by a local company. From estimate to final work performed, the staff were great and the job was handled to my satisfaction. I highly recommend Koala if you need your house insulated

This is a first class outfit. Always polite and on time. I had a small crawl space to insulate and needed R30 so foam was my only real option. Not the best of working conditions since the space was a little tight but the guys got it done just as well. If you need insulation work done I highly recommend them.
