LP Insulation of Naperville is the best! I cannot say enough good things about them. We had gotten an estimate from another company and it was more than double. Everyone that has interacted with me throughout this process has been very professional, polite, responsive. We went with the cellulose insulation which made such a difference immediately after they finished, Thanks Guys

Owner John came out to provide us with a quote for a smaller job in the crawl space beneath our kitchen. He was very friendly, gave us a reasonable offer, and informed us about energy rebates that would expire at the end of the year. We booked the job. The crew arrived promptly and got to work immediately. Our crawl space is not easily accessible (through an old hopper window located over the utility sink in our laundry room). They cleared out the old insulation and cleaned up years' worth of detritus. They were finished in under two hours and left everything tidy. Clear before-and-after photos were shared with us. Great work! We can't wait to reap the benefits of a well-insulated space.

I had Koala spay foam my cathedral ceiling that lacked any insulation. Guys came on time and performed the work within guidelines. Area was prepped and sprayed well. No funny residue and was able to return home the next day. I was very pleased with the workmanship, quality and attention to detail. My AC unit no longer runs as often as it did. Now I can’t wait how this will perform in the winter, but I can already tell a drastic difference in temperature. I would highly recommend.

Patrick McKernin★★★★★a week ago

Koala insulation came through for us. We wanted to have or attic insulated with blow in material John Anthony came and gave a quick quote. He showed us what they were going to do and gave us a fair price. The job was scheduled right away. The team came on time and left the house as clean as it was when they got there. It has not been too cold yet this year, but we can notice a positive improvement. No drafts or cold ceiling now. 18” deep throughout the entire attic. They gave us very good complete pictures of the before and after of their work. Very satisfied and will recommend them to others.

We hired Schmidt Exteriors to replace all our old cedar siding with the fiber cement siding and they did an outstanding job! His crew was awesome and they completed the job in tough conditions and on time! Very honest & dedicated company. I would hire them again tomorrow!

Jane McGinley★★★★★7 months ago

We waited years to replace our sliding windows to those that open up and down. Five stars aren't really enough to tell how pleased with our new windows & doors. Everyone we dealt with from Mike to the installers & painters were professional and did a great job for a great price. We love the difference they made in our home. We HIGHLY recommend this company.

Brian Sanford★★★★★10 months ago

Recently we had a large bay window replaced. This was a very large job. Dealing with Schmidt Exteriors from the beginning to the end was awesome. The quality installation done by highly professional workers was truly 5 stars. The paint crew that came after the installation also did a professional job. I would highly recommend them!

ARC recently completed an insulation project in my home that was built in 1862. The home had zero insulation in the attic. We worked with David and his team and they were absolutely fantastic. Super professional and a pleasure through the entire process. My home is super cozy now! I highly recommend ARC.

Box sills were insulated in October. My home had a mouse problem for the past couple of years and paid a Pest Service (all they did was put bait boxes outside). Found information to insulate your box sills where the small leaks are allowing cold air and pests to come in. Wish I knew about this solution before. Now, absolutely no evidence of mice, spiders, webs, small bugs..... All perfectly and expertly sealed. Basement is warmer and less damp and wood floors above are warmer. ARC Company was excellent. They were easy to talk to and the crew was helpful and knowledgeable. Everything was sealed off and debris expertly removed . Old insulation had some mold AND dead mice.... UGH!!!! Everything was cleaned up and installed perfectly. Crew was professional, courteous and outstanding.... Wasted too much money on Pest Service and should have insulated with ARC . Highly recommend services and crew. Money well spent for great services and results.

Great communication from start to finish on my project!! David (initial consultation and sales) was very easy to work with, very patient, very knowledgeable. The crew (Victor and Pedro) were professional and friendly. I appreciated how hard they worked, their attention to detail, and how clean they kept everything. The insulation looks so good — what a difference!! We will definitely hire ARC again!!

Innovative Insualtion Solutions are the best. They sprayed closed cell foam in our open attic spaces. Communication prior to the project beginning from the office regarding timing and how the job would go was excellent. The crew sent over to my home were even better. They communicated well, showed up on time each day and were respectful of my home...three things that I, as a small business owner, can really appreciate. The owner, Richard Spies, also showed up onsite to make sure all was well and to answer any questions that I had. A really great experience from start to finish. I would highly recommend them for any insulation work needed in your home.

Natasha Mahon★★★★★3 weeks ago

Great communication, easy scheduling, fair pricing. Richard was great to work with and his team was friendly, clean, and efficient. We got 3 quotes for insulation and thIs was by far the most reasonable. We saw the difference in our energy needs almost immediately - we would keep the thermostat at 73 and our bedroom upstairs would not get warmer than 68. After the insulation was added the room temp is exactly what we set the thermostat to. Glad we did this before winter began. Would definitely recommend this company to friends and family.

Anix Inc★★★★★a month ago

We recently worked with Innovative Insulation Solutions, Ltd., and I couldn’t be happier with the results. From start to finish, their team was professional, knowledgeable, and efficient. The crew arrived on time, worked neatly, and made sure every detail was done right. Home feels noticeably more comfortable, and the quality of their spray foam insulation is outstanding. It’s clear they truly care about their customers and take pride in their work. Highly recommend them to anyone looking for reliable insulation experts!

OTS Chicago Insulation provided an outstanding service that immediately resolved the issue of our room temperature imbalance. The team was punctual, professional and finished the work in one day. We really had a great experience

Noah Karpman★★★★★7 months ago

I live in Buffalo Grove, IL, and recently hired OTS Chicago Insulation to insulate my crawl space and I’m extremely happy with the results! After doing some research and calling a few companies, I chose OTS because of their professional approach and detailed consultation. Ofer, the technician who came out, was knowledgeable and explained the benefits of crawl space insulation, including how it would improve energy efficiency and reduce moisture issues in my home. It’s been a few months since the installation, and I’ve noticed a big difference. The floors on the first level are no longer cold, the air quality has improved, and our heating system isn’t working as hard this means real energy savings! If you're looking for a reliable insulation company in Buffalo Grove to handle your crawl space insulation project, I highly recommend OTS Chicago Insulation. Great customer service, excellent workmanship, and noticeable results.

We recently contacted OTS Chicago Insulation to evaluate our office space in Arlington Heights, which was always cold, especially during the winter months. Their team was professional, knowledgeable, and provided a thorough estimate along with a clear explanation of the insulation options. The installation process was smooth, and the difference was noticeable right away. Our office is now much more comfortable! We highly recommend OTS Chicago Insulation for anyone looking for quality work and outstanding service. Thank you from the team at Chicago Garage Door.

I have been very busy, but wanted to make sure that I posted this review. I had this company do major work in my home several weeks ago under the supervision of "Ken" and they were wonderful. The insulation work they did in both my attic and crawl space was efficient and very professional. The crew of men that performed the work I found to be considerate and courteous. The clean up was complete. I highly recommend their business!

Ron Gia★★★★★a year ago

We were very pleased with the services provided by Anthony, Dave and their crew to improve the energy efficiency of our home. They showed up on time (actually 15 minutes early). Dave reviewed the scope of the work they would be performing and gave me assurances that put my inquiring mind at ease. Their crew were well trained. They were neat and upon completion cleaned up after themselves. We couldn't be more pleased with our decision to utilize their services. Thank you Anthony and Dave. Sincerely, Ron G.

These guys are the real deal folks. A few years back our newly purchased house had a mice problem. We were given quotes for sealing and doing some insulation that were so expensive. We did the sealing and held off on insulation until this winter when our heat distribution was terrible. Enter Ken and Tyler from building energy experts. I could tell from the moment they showed up how thorough they were. Ken explained things SO well and pointed out several weak points that were contributing to our issues. Anthony the owner followed up with a quote that was not only reasonable, they had gone through the trouble of taking off rebates that they knew would be covered by our gas company. This was certainly never mentioned by their other companies much less actually applied in a quote. Day of service the guys showed up early and were ready to go. Dave, Tito, Jason and Tyler were incredibly thorough and efficient and it was a bigger job once they got into our weird old house and realized the full scope of the project. Again they explained everything so well and truly went ABOVE AND BEYOND! We feel so grateful to have found this company!

USA Insulation came out and blew in the pink stuff up to R49. The crew arrived on time, was professional and very thorough with what they were going to do before starting, communicating during of their progress and then a 'show and tell' after the work was completed. Cleanup afterwards let my house cleaner than before they showed up and only took them around 1 1/2 - 2hrs from start to finish (for a 1425 sq ft attic). The entire process, from start to finish, exceeded my satisfaction and we will most certainly be recommending USA Insulation to our friends and family.

Will Williams★★★★★2 years ago

I previously used USA Insulation and was totally satisfied. When another area of my home needed insulating it was a no brainer to contact them. The second time around even better results, Jose and Jason did an outstanding job!

James Kasprak★★★a year ago

The garage is now easily heated with a basic space heater. Insects can’t move within the walls so have noticed a more insect free space. Problem is they spackled in too low of temperatures, now looks bad and ceiling pieces fall out easier They came out again to fix but they said it was spackled and they only do that once as per agreement. Maybe give me the option to wait and spackle in proper temperatures would be good because we want to paint. Better then 3 stars I give 3.5 😀

Frequently Asked Questions — Spray Foam Insulation in Aurora

These are the questions Aurora homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 37% typical energy savings. Compare the 10 verified Aurora contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Aurora?▼
In cold climates like Aurora, IL, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in IL typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Aurora?▼
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Aurora, IL. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Aurora?▼
For cold climates like Aurora, IL, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with IL building codes can recommend the exact specification for your home.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Aurora, IL?▼
In Aurora, IL and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Aurora costs $2,000–$6,000. Most Aurora homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Aurora, IL?▼
When searching for a spray foam contractor in Aurora, IL, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Aurora contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Aurora for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
