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.

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!

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.

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.

Jay Smith★★★★★2 months ago

I couldn’t be happier with Chicago Green Insulation. I had a unique project, and got several quotes. Tom got the job not because he was cheapest, (which he was) but because he understood my needs and came up with a unique approach that saved time and money. I didn’t get a cheap job, I got a great job, done for less money because of Tom’s expertise.

Laura★★★★★2 weeks ago

I contacted Chicago Green Insulation to see if anything could be done to prevent my pipes from freezing again this winter. Tom called me back and was over to inspect my house by the next day. He did a thorough inspection of the areas where I’ve had freezing and went down into the crawl space to see how well it was insulated. It turned out that my crawl space already was insulated but Tom alerted me to several other things I could do to help potentially avoid having my pipes freeze. A couple of his suggestions were ones I could do on my own while others will require professionals to do the work. Tom very nicely offered to help get a quote for one of the jobs with someone in the industry that he has worked with for many years. Although I wasn’t able to hire Tom to provide any insulation work for me, I really appreciate how much he has gone above and beyond, even long after he knew I wasn’t going to need his services.

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.

Great response…Called and had a site visit within 48Hrs, Booked and completed within a week. Granted it was a smaller job, but Wes showed up promptly and ran me through the process, questions were asked and answered. Very happy with the results.

Andrew Larsen★★★★★2 years ago

We are super pleased with Dr. Energy Saver and the work they did on our home! Our house did not have the proper insulation which was leading to uncomfortable nights and expensive utility bills. After the service was performed the house was instantly more comfortable. The reason we chose this vendor was due to the thoroughness to diagnose the situation vs. writing a quote trying to make a quick buck. The team that performed the work was easy to work with and professional every day.

Cathleen Dohrn★★★★★a month ago

DES came to look at our small space that needed insulation, talked through the details, and met the price of the competitors who just sent over a quote (or didn't respond at all). The workers came when scheduled, walked me through expectations again, and completed the job on time, cleaning up their mess. Everyone was professional and respectul.

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.

Project Manager (Lanny)★4 years ago

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 Buffalo Grove

These are the questions Buffalo Grove 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 8 verified Buffalo Grove contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Buffalo Grove?▼
Homeowners in mixed climates like Buffalo Grove, 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 Buffalo Grove?▼
For most homes in Buffalo Grove, 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 Buffalo Grove, IL?▼
In Buffalo Grove, 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 Buffalo Grove costs $2,000–$6,000. Most Buffalo Grove 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 Buffalo Grove, IL?▼
When searching for a spray foam contractor in Buffalo Grove, 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 Buffalo Grove 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 Buffalo Grove 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.
