Amazing work! Amazing and trustworthy people to work with! Best prices around. Don’t bother calling anyone else for your insulation needs!
Beautiful work and timely response when I needed a quote. Prices are very good and the work was impeccable. Energy savings since getting Spray foam insulation has been the number one reason I chose Southwest Insulation.

We had an all around great experience with Northern Insulation. We had a catwalk installed, complete removal of our old insulation and then fresh put in. The team air sealed the attic and accommodated a few additional requests from us as well. Ryne was very patient and took time to answer all of our many questions. The whole team was very communicative and they did a great job showing up on time, sealing off the house to prevent irritants from escaping the attic and cleaning up. This type of service is extremely rare! Would highly recommend.
They are one of the best you can find. These guys will save you money on your utility bills. Mine went down dramatically and my house is so much more comfortable now even in the summer it stays cooler. Thanks.

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!!
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.

Richard and his team at Innovative are top notch professionals that have been delivering a high level of service since their inception many many years ago. Attic insulation, spray foam, sound proofing etc, you will not find a better, more concerned contractor so stop your search here. As a general contractor, I partner with them on all of my projects including my own personal home. Thank you for great service Innovative!
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.
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.

This company is an A+ company!!! Responsiveness, price, customer service, and installation all went beautifully. Highly recommend them. It was always cold above the garage in winter and hot in summer. We can really feel the difference so much nicer. After their home insulation audit they blew in about 12 inches above the garage and sealed all the lights and fans and a few more items. Great!
Ofer and his team are the best in the business! They were timely, professional, reasonably priced, and did an excellent job. Highly recommend!
I had a really great experience with Clean Air Doctors. It was easy to set up an appointment, and they made themselves available on short notice. They were prompt, and very understanding when I was the one a couple minutes late for our appointment. Our dryer is in a tough/tight spot, and they really went above and beyond to access the vent to clean it, and then they taped it to alleviate the lint build up issues we were having (the vent had been installed without any tape to seal the seams, which was part of our problem). I would highly recommend Clean Air Doctors... they were kind, quick, and did a good job.

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.
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.

We had an outstanding experience with Green Attic. They JUST completed mold remediation, corrected our venting issues, and installed new insulation and every part of the process was handled professionally and thoroughly. The crew was friendly, efficient, and clearly took pride in their work. Beyond the quality of the work, we felt very comfortable having them in our home. They were respectful and courteous. What impressed us most was their attention to the cleanup. After such an extensive project, they left our home spotless. You would never know they had just completed major attic work. Most companies are not that thorough. We truly appreciate their workmanship, professionalism, and care for our home. Highly recommend Green Attic!
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.
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.

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.
Called Tom to get some perspective on a moisture issue I'm having in my attic. He was very honest and shared that the issue is not something he needs to handle and gave me some technical knowledge and small tips to solve the problem. He generously gave of his time to help me solve the problem for much less money! Very friendly and approachable. Thank you, Tom!
Tom, the owner, came out to visit our home on short notice because we were experiencing vastly different temperatures on the 2nd floor of our 1890s home. He took a look at the situation, gauged temperatures, structure, and gave practical, honest alternative solutions to insulation. Since adding insulation would require certain renovations that we weren’t looking to do, Tom suggested dehumidification and hvac modification, and gave the names of reliable professionals from his contacts. He did not try to make a gratuitous sale. He maintained integrity and focused on problem-solving. So if you prefer to work with smart, innovative, and honest companies that truly want to fix the problem, give Chicago Green a call.

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.

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!
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!

I've used Reynoso Insulation for several insulation projects, and they’ve consistently delivered excellent results. Their team is reliable, always on time, and easy to work with. One of the things I really appreciate is their attention to detail. Any time I asked them to adjust or level out insulation, they handled it without hesitation. Their work made drywall installation smooth, with everything fitting perfectly on the studs. I highly recommend them for anyone looking for quality insulation work done right the first time.
Jose and his wife and very customer friendly. Jose is knowledgeable about building construction and climate control. Insulation workers and professional, kind and clean up after themselves. Highly recommend Reynoso . Thanks again! Guillermo P
Reynoso Insulation did a great job with our second floor. For years, extreme temperatures outside, could be felt inside. This prevented us from even going upstairs in the middle of the Summer because our AC just couldn’t keep up due to the heat. And in the Winters, the heater would work overtime. We finally had enough and searched around for someone to insulate the whole upstairs. Reynoso insulation suggested a contractor to us to cut the drywall. We ended up hiring him. He was confused with the start of the project and showed up a bit late. And to finish the project, wouldn’t show up til 10 some days. But he ended up doing good work in the end. When it comes to the actual company, Reynoso Insulation came on time (8 am) for the days they worked. They worked quickly and efficiently as well as cleaned up nicely. Now, with this Summer’s heatwave, our AC is finally working like it should upstairs. Letting us know that the insulation was a job well done.

I am extremely happy about the whole process from start to finish with Daniel, and Smart Insulation. Daniel was very thorough on his inspection and offered a few different strategies for insulation in my attic. Gave me a fast estimate and was even willing to do the job on a Saturday! With these below zero temps this week, I already notice the difference. I definitely recommend this company. Thank you! -Lauren
Excellent professional workmanship. They went beyond what was quoted and did some additional repair work that was needed to ensure that the crawl space would be sealed perfectly for the next winter. The team worked hard and diligently getting the work done efficiently. They cleaned up when finished. Five stars.
This company is AMAZING. They came out and sprayed foam insulation in my attic, and they did it quickly and efficiently. The crew was very friendly, and they didn’t leave a mess when they were done!

Very good experience with Thermaseal. They did spray foam insulation in my attic. Clear communication, fast work, and a huge difference in temperature. Some of the earlier reviews mention communication and timeliness issues. We primarily worked with Chris and had no problems there. There would have been a fee to pay by credit card, but there were multiple payment options that did not have fees.
Wow! The two man crew that installed vents and more insulation in my attic did a great job. Plus the cost was very reasonable for the amount of time spent, the blow in insulation, and the vents that were installed. I should also mention that the sales rep. that represented TSLS was very professional and highly experienced. He gave me good advice and a fair price. I highly recommend ThermaSeal/Lakeside, Cary, IL
I couldn't be more pleased. John was amazing. Addressed all of our concerns, made recommendations I never thought of and even explained why something I wanted wasn't worth the money even though what I asked about would've cost us so much more. John was very honest and if he didn't answer calls he called back in a prompt manner. Very fast work, very thorough work as well. And it was a lot less than I anticipated. We had a spray foam coating on our main walls, sprayed heavy in the sill, and batted the rest. From our previous to the remodel we can tell how much better our home is insulated and how much quieter it is with even the thin spray foam.
