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.

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

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.

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.

As a home builder of many years, I can tell you that Not all contractors are alike. I have used Chicago Green Insulation several times, on different projects. And I can say, they did an excellent job every time. Their spray crews were dependable, and got in and got it done. Tom Decker is experienced and knowledgable in the field of building insulation, and most important, Reliable. Two thumbs up!

Jason Sisk★★★★★10 months ago

I hired Tom on recommendation from a friend to insulate a large family room that had been gutted to studs. Really appreciated Tom coming out in person to see the site and estimate scope and cost. On initial install, there was an issue after the crew had left. Upon hearing that I wasn't satisfied, they re-dispatched a crew to make it right the very next day. I am very happy with the results, and am happy to have made this investment in my home. Marla was great to work with, and the crew lead James was extremely courteous, professional, and conscientious in our home.

Rafael Labrador★★★★★2 months ago

Tom came to the house promptly to address my issue with pipes freezing. He is extremely knowledgeable and patiently explained the options and provided helpful pointers. A no pressure process, I never felt like he was trying to upsell me.

Absolutely outstanding work from beginning to end! The project manager, Javier, did a fantastic job. The project involved the removal of old insulation from the attic and walls of one room. From the initial planning, execution of the project, to the final cleanup, everything was handled professionally. I highly recommend this company for their excellent service.

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 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!

We used Reubens spray foam for our pole building. Julian was very prompt and responsive. they came out immediately for the estimate. After a very fair price was given the crews came out and spray foamed our pole building walls. And also did blown-in fiberglass for the ceiling. They guys were top-notch. Highly recommend!!

Lindsay Rafayko Santora★★★★★8 months ago

Highly recommend Rubens Spray Insulation! We needed to have two walk-in attic spaces and a portion of ceiling between them spray-foamed. There was a 5 month gap between when Julian came out for an estimate and when the work was actually completed because we were waiting for another project to finish up first, and they were responsive and understanding the whole time. The guys who did our work were excellent - super nice, professional, and did a wonderful job. The quality of work is fantastic and we noticed an *immediate* difference in terms of how well our house retained heat. Thanks guys!

Have used Chicagoland Sprayfoam multiple times for various projects. They’re honest, respectful of clients needs and thorough with their work. Would definitely use again. They’re extremely busy but worth the wait IMO.

Called a few times and left a message but no answer. Drove to the address from Northbrook because it says they close at 6pm and I arrive to a residence. No business advertisement and no answer at the door.

Frequently Asked Questions — Spray Foam Insulation in Des Plaines

These are the questions Des Plaines homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 9 verified Des Plaines contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Des Plaines?▼
Homeowners in mixed climates like Des Plaines, IL typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Des Plaines?▼
For most homes in Des Plaines, IL, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
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 Des Plaines, IL?▼
In Des Plaines, 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 Des Plaines costs $2,000–$6,000. Most Des Plaines 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 Des Plaines, IL?▼
When searching for a spray foam contractor in Des Plaines, 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 Des Plaines 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 Des Plaines 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.
