Sal and his team are excellent. great communication, reasonable price, professional of what they do. I hired them for adding close-cell spray foam to my concrete crawlspace walls and rim joist. Sal took the time and explained the type of services he offers and recommend what's really necessary - not bare min. but decent enough to be done within my budget. i got several quotes before him and felt he was being honest and I was happy to move forward with them. turned out, the project went smoothly and completed everything listed on the quote. also, his team cleaned up the work area nicely. I would strongly recommend Solar Spray Foam Insulation Inc, Sal and his team for any insulation project. get insulated, lower down energy cost, better air quality and seal out the draft and critters.(fyi, for spray foam, it is recommended to not to occupied the house for at least 24hrs same for any contractor)

I couldn't be more impressed with Sal and his guys from Solar Spray Foam Insulation. From the start, Sal couldn't have been nicer, more informative or more helpful. He explained what he proposed to do and why very clearly. And they did an amazing job removing the old insulation from my attic and putting new insulation in. The whole team was very pleasant and polite, they worked really hard, they did the job quickly, and they cleaned up impeccably after they were finished. On top of all that, the price was extremely reasonable. If you need old insulation removed and/or new insulation installed, you can't do better than Sal and Solar Spray Foam Insulation. I'd give them 10 stars if I could!

Rhys McIntyre★★★★★7 months ago

Sal is great! I prefer texting when it comes to communication and he obliges. He was very flexible with scheduling the insulation and upfront on what avenues we should take. Pricing was very fair and competitive as well. Can't recommend him enough!

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

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!!

James Parr★★★★★3 weeks ago

I had a great experience with Arc Insulation. David came out to give the initial quote and was incredibly patient as I gathered and compared other estimates. He walked through each one with me in detail and was honest about what was better or not in those quotes so I could feel confident I was getting the best value. His knowledge and transparency made the decision easy. Mauricio and Antonio completed the installation and were fantastic to work with. They explained the work step-by-step, thoroughly covered and protected the areas being insulated, took detailed photos throughout the process, and cleaned up completely when finished. They were professional, respectful, and patient in answering all my questions. Overall, I really enjoyed working with the Arc Insulation team and will absolutely reach out to them first for any future insulation needs. Highly recommend.

From the initial quote to the install, Green Attic, was accommodating and fast. Frank came out on May 20 and squeezed up into the attic space. Found black mold on the rafters from poor ventilation due to a broken fan. I appreciated his honesty and recommendations. Ten days later, Edgar and his crew (Omar and Rigoberto) arrived. They did a great job remediating the black mold in the attic, adding thick insulation, baffles and replacing the attic fan with a solar powered fan for continuous attic air exchange. When they finished, Edgar showed me the final air flow and his crew were very respectful of the property, cleaning and tidying up the work area. I would recommend Green Attic to anyone needing mold remidiation and insulation.

William McCloskey★★★★★3 weeks ago

We had four Green Attic workers involved over our three day project. The first day Alvaro & Jeff worked diligently at completing the mold remediation and insulation installation. They were polite, hard working and respectful of our home. The second day, Mario completed the initial mudding & sanding of the installation holes. Then on the third day, Mario and Sammy completed the final sanding and the opening of the soffit vents. These two men were also hard working and respectful of our property. The entire job went smoothly and comfortably.

S Keenan★★★★★2 weeks ago

Our house is drastically more comfortable after an air sealing and insulation project. They were also able to accommodate our request for a positive pressure blower door test (rather than negative), though it take a bit of back and forth to get that sorted out. They did very good work and I will definitely be reaching out again if we have any future insulation projects.

Echo Tec is responsive, professional and efficient. They did a wonderful job with my home insulation.

Nicola Genelly★★★★★a month ago

It was a pleasure to work with Brian, Andrew, and their family business. I recently had Eco Tec at my home doing wall cavity insulation. My house is over 100 years old and largely stucco exterior, both of which present more challenges, but they were able to do get the job done mostly from the outside. I only had a short turn around time for completion of the work, repair, and clean up. Brian went above and beyond to get my final clean up done by my required deadline - thank you Andrew and Ryan. I want to acknowledge Ruben for his efforts and thorough work getting my drywall repaired, painted and back to normal. Brian is very responsive and has such a friendly, calm and competent attitude. I thought my initial quote was very reasonable considering the scope of the work. My final invoice and payment due amount was really good value. I would definitely recommend Eco Tec Insulation.

I will definitely recommend them to anyone .

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.

"Exceptional Service, Exceptional Comfort! I recently had the pleasure of working with Metro Insulation to upgrade the insulation in my home, and I couldn't be happier with the results. From start to finish, the team exhibited professionalism, expertise, and a commitment to excellence that truly sets them apart. First and foremost, their communication was outstanding. From the initial consultation to the completion of the project, they kept me informed every step of the way, addressing any questions or concerns I had promptly and thoroughly. When it came to the installation itself, the craftsmanship was top-notch. The crew arrived on time, worked efficiently, and paid close attention to detail, ensuring that every corner of my home was properly insulated for maximum energy efficiency and comfort. They were respectful of my property, leaving the work area clean and tidy each day. Not only did Metro Insulation enhance the energy efficiency of my home, but they also significantly improved its comfort level. I've noticed a dramatic difference in temperature consistency throughout the house, and I'm already seeing a reduction in my energy bills. Overall, I can't recommend Metro Insulation highly enough. If you're looking for a company that delivers superior results with a commitment to customer satisfaction, look no further. Thank you to the entire team for a job well done!"

Had a new garage built and Josh from Metro came over measure and gave me couple different options and recommendations of what was best. Very transparent and honest. The price was good. They did an amazing job. Very professional and knowledgeable.

Foam Slab Jacking I recently worked with Metro Insulation in Rockford for concrete foam jacking to lift and level several sunken and uneven concrete slabs, steps, and a ramp around my property—and I couldn’t be more pleased with the results. From the initial call to the final cleanup, their team was professional, punctual, and experienced. Josh walked me through the entire process, explaining how they would inject high-density polyurethane foam beneath the problem areas to raise and stabilize them. The work was done efficiently, using relatively small injection holes, and the crew was extremely respectful—especially when working inside my home and in the basement. The slabs were challenging to lift, but they got them level again. They filled some voids under the concrete as well and made sure that the concrete is solid again. They also went the extra mile to protect nearby finished surfaces throughout the job. Overall I could not be happier with my decision to use Metro Insulation for foam slab jacking.

We just had our attic and crawl space insulated and a moisture barrier put in. The crew showed up on time and every one of them was polite and professional. We could tell they had a lot of experience working together because they were super organized. While the boss, Dave, walked us through the process in detail, making sure we understood the job, behind him the crew set up quickly and efficiently, treating our home with respect. They were finished right on time, too, and left our house looking as if they had never been there. Before they left, Dave showed us their work and explained how these improvements would make our home more energy efficient. Every crew member made sure to say goodbye to us. They were amazing people! We highly recommend Building Energy Experts.

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.

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 Elgin

These are the questions Elgin 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 Elgin contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Elgin?▼
In cold climates like Elgin, 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 Elgin?▼
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Elgin, 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 Elgin?▼
For cold climates like Elgin, 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 Elgin, IL?▼
In Elgin, 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 Elgin costs $2,000–$6,000. Most Elgin 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 Elgin, IL?▼
When searching for a spray foam contractor in Elgin, 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 Elgin 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 Elgin 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.
