Such a fantastic company to work with! Taylor was not only friendly and personable, but also very prompt and thorough in his communication. Very fair in pricing, especially when we just needed to satisfy insulation requirements for an inspection item found when selling our home. Top notch from beginning to end - would highly recommend!
Taylor and the Thermal Shop team were great to work with. Taylor was incredibly thorough, explaining exactly what he recommended and why. I really appreciated that he provided several options at different price points so we could make an informed decision. He and his team completed the work in a timely manner (within one week), and while the pricing was competitive with other quotes, Taylor’s "above and beyond" service is what truly set them apart. Photos are showing the initial removal of the old insulation, then the final product after the new insulation was blown in
Hey Jacob, I wanted to let you know that I am very impressed with the job your guys did. By far the best one I've had installed for me. The price is fair and the attention to detail was fantastic. Kudos to you and your guys, I'll be calling when it's time for the next one.

They did an excellent job spray foaming our unfinished basement. Mark was very easy to communicate with & responded quickly. The crew was professional & left the job site really clean after. We would definitely recommend them.
They did an excellent job of foaming my metal building. I wanted a 1" layer of closed cell foam to "seal out" the wind from coming in. They sprayed more than an 1" almost everywhere. It has been a year and it has held up great. I can't recommend them enough. I will say they are a little hard to get in contact with but it is well worth the effort. I'll try to post a couple pictures.
Just had Midwest poly insulate our basement with spray foam. They did a great job and protected and cleaned up after the job. I would highly recommend them for this type of work.

We have a cape cod 1.5 story home. The attic area was finished when we bought the home but was unusable because of temperature extremes. The old insulation collapsed to less than 1.5 inches over the years. The roof deck on a sunny 75 degree day would hit 110 degrees radiating heat into the space making it nearly 90 degrees inside the space. After Classic came in and did our roof deck and gables on the same day as the previous example the foamed roof deck never exceeded 73 and the conditioned space stayed at the 72 degree set point. The installed mini split system hardly had to run mostly just air circulation. Long story short we just gained 450 sq ft of usable living space. The owner is actually the applicator and truly cares about the quality of the work preformed. It's beautiful comfy and after shopping a few others in the market one of the least expensive. Thanks Classic =)
Outstanding job!! Would highly recommend. Mark was a pleasure to work with, knowledgeable, and extremely efficient. Completed my 50x36x14 building in 2 days including inside of overhead door. The building is tight and tidy, as promised. Thank you Mark for the professionalism, customer service, quality workmanship. If you are looking for quality and value, Mark and Classic Spray Foam is your call.
Mark and his crew went above and beyond when spraying my 40x60 shop. I would recommend them to anyone!

Had spray foam done on my house addition and crawl space by Johnny Andersen and Joey Ohlgauser. They were very professional, very quick to get our project done and did an outstanding job. 100% recommend this company and crew
Eric Reents with Kinzer Construction installed a new downspout on our property. Eric was quite the professional and friendly. A craftsman in his trade. Work was completed in a timely fashion. I would definitely recommend Kinzer construction for your building needs.
Justin was extremely responsive and easy to work with to get the project priced and scheduled. John and Joey did the installation and were friendly and efficient. They were very communicative, letting us know what to expect. We also appreciated that they took care to keep things clean and tidy…no mess for us to clean after they left!

The service is outstanding! I would highly recommend Eastern Iowa Spray Foam & Waterproofing. Justin is great to work with. His communication is excellent from start to finish. The work is done efficiently and tidy. Once the work in my basement was completed there was a rain storm and a little seepage came through. Nothing near what it was before but Justin came out that same day so he could see it to pinpoint the exact spot and had it fixed as soon as it was dry enough for them to do the work at no additional cost to me. The above and beyond service is hard to find but I have been fortunate enough to work with a company that has it!
Justin is AWESOME!! He is very knowledgeable, honest, has beyond great communication, and is incredibly efficient. He has fixed a number of cracks in our foundation in our basement and we have had no further issues with the cracks after his work was completed. Highly, highly recommend Justin/Eastern Iowa Spray Foam & Basement Waterproofing!
FANTASTIC company to work with!! I had water in my basement and needed a sump pump installed (didn't have one in the house). I had been using two large shop-vacs constantly for several days to keep up with the inflow of water - a very exhausting task. Justin was able to work his schedule around and get to my house several days quicker than anticipated. His workers showed up on time, did a terrific job, worked diligently to complete the job in one day, and even mopped the basement when they were done! I can't say enough good things about this company!!!

Jim and his crew did a fantastic job on removing lead/asbestos from a home remodel we are working on for a customer. HIGHLY RECCOMEND!
DO NOT DO BUSINESS WITH THIS COMPANY!!! If I could leave zero I would. We were shorted 3-4 inches of insulation in our attic. Lucas came to look at our attic and blamed it on a derecho. I watched him as he measured various spots in attic and all measured 12 to 13 inches; supposed to be 16. We didn’t have a derecho here. Also how does a derecho remove that much insulation evenly through out the attic? There was no evidence of insulation outside of our house. Since we discovered this two weeks after our one year warranty expired he said they would come back but they would charge for this. So he wanted us to give them more money to get what we should have received originally. He finally said he would talk to the owner and get back to us and now Lucas is ghosting us! Terrible business!
