Hands down the best insulation in the business!!! Drew was EXTREMELY knowledgeable about all possible products that I could use on my home. He and I went over all options with the pros and cons of each. I am super picky to say the least, so I check everything very closely.They spray foamed the exterior walls and blew in cellulose in the attic. I was impressed with the attention to detail. Not one single area that didn't have the correct amount of insulation or foam extruding past the 2x6’s on the exterior walls. When they left, the job sight was as clean, if not cleaner, than when they arrived. And to end the already great experience, my bill was cheaper than we had discussed. Premier Foam is second to none, 10 out 10, and I will never use anyone else!!!

I cannot say how great these people are. It was a last minute Schedule to get done They were able to work around the last Minute request. I had to get my sighting replace. I've been waiting for a year and they finally said we're here to do it, so that was the perfect time when everything was off to get it insulated. Thank you so much for the hard work.I noticed it as soon as I get Home.The back bedroom was 5 to 10 degrees cooler

Foam Co. was very easy to work with. We had new insulation blown and sprayed in. They were able to get it done in a day and went above and beyond providing pictures of the install and working independently. They communicated promptly and clearly throughout the process.

James Leeβ˜…β˜…β˜…β˜…β˜…2 months ago

Very professional company from the beginning of the project to it's completion. Every person was nice and respectful. When they say the workers will start at 7am that is what they ment. They blew in our new insulation. They came right in, introduced themselves and got to work. The project did not take long at all and they cleaned up behind themselves. The price for the job was nice too. If we need any more work done we will be calling them again . James and Brenda Lee

While I haven't used Missouri Spray Foam Insulation myself, I've had the opportunity to interact with their team and was thoroughly impressed by their professionalism and depth of knowledge. They were incredibly helpful and took the time to explain the benefits of spray foam insulation in a way that was easy to understand. Their dedication to providing top-notch service is evident, and I have no doubt they deliver fantastic results. I'm looking forward to potentially working with them in the future and would confidently recommend them to anyone considering spray foam insulation.

I was extremely pleased with this whole process. From Scott and his team coming out to give the bid to the two gentlemen that came out to do the install of my insulation. Very professional and worked very quickly. Paid very close attention to detail and explained steps as they went. You will not be dissatisfied at all if you choose this company. They were also very affordable. Thank you Scott and your entire team for such a great job. I will make sure that I share my experience with friends.

Koala give a free assessment. In the quoting process they go over every aspect of the attic space and what it needs and nice to haves. They gave me a few different options in the quote to best suite my budget and what I wanted. The work was done about a week ago at time of this review. I think it will be hard to quantify the effect right of way adding insulation to the attic, but it is supposed to help keep hot air out of the house in the summer and keeping the heat in in the winter. I am pleased with how professional both the quoting person and the install crew were.

I was greatly satisfied with the services rendered by KOALA. Their employees demonstrated good teamwork and time management. They arrived on time and came well prepared. Each employee was very professional (very polite). All of the work was completed to my expectations - including their good housekeeping skills. All debris was removed inside and out. Surprisingly, the price was very affordable. Moreover, the smiles and gentlemen-like behavior was greatly appreciated.

Got us filled up to R49 and some insulation rolls. Ryan and team kept me well updated during the process of blowing in the insulation. They took lots of pictures of the attic. I was really happy and would recommend. We had a delay in the initial quote which they said was a new system, but once we got on track everything was great.

I dont even know where to start here! Chris took a bunch of time on a sunday while he was with his family to talk to us about our issues, what we needed and took the time to really explain everything and educate us about insulation, and he did all of this within ONE HOUR of me reaching out to get a quote. Chris told us what we needed, gave us such a good price and then guaranteed his work and our happiness and he wasnt lying! I just got home from work and checked my attic and they did such a great job on blowing in additional insulation for us since the home builders couldnt get it right not once or twice, they came out and got us right within 2 hours. Im so glad we used st louis insulation and we will continue to do any business that we need with them and will reccomend them to anyone needing insulation, i cant explain how wonderful this entire experience with them was and his prices are extremely competitive. Thank you so much chris and your entire team!!

I had a great experience with St Louis Insulation. The quote process was quick and the price was very reasonable. Everything is done through their portal, so chatting, quotes and payment are easy. The day of the install was just as good. Brandon and his crew were fast and gave me pictures showing the quality of the work. They cleaned up and were very polite. I was impressed. They also showed up a little early!

Eric Farsonβ˜…β˜…β˜…β˜…β˜…2 years ago

Great experience. They were super friendly and not only gave me a quick bid for adding insulation in my attic but also gave me a few other tips for making my basement more energy efficient. I appreciated the overall process including approving the bid and the installation date via a link sent via text. This was much easier than calling back and forth. The installers were also friendly and efficient. The price was very reasonable and well worth it.

Foam Engineers has exceeded my expectations. I’m a project manager for a home renovation company and have worked with Foam Engineers on my last two projects. Their pricing is very competitive, and their service is outstanding. Dave and his crew installed both spray foam and batt insulation on my most recent project. They were prompt, professional, and maintained excellent communication throughout the process. They went above and beyond in both scope and execution. I’ll continue to use Foam Engineers for future projects and have already recommended them to my colleagues.

Leslie Mortonβ˜…β˜…β˜…β˜…β˜…3 months ago

Very impressed from start to finish with Foam Engineers! Mindy came out for the estimate and was extremely thorough in explaining the process of installing cellulose insulation and the resulting benefits. The estimate was very detailed, including photos.The installation took place yesterday and we had a fabulous crew! Alex was the lead and impressed me with his knowledge and professionalism. Colin, Dylan, and Tony were all very competent and skilled workers as well. All were committed to the successful completion of the project in a timely manner. I had to run an errand and felt comfortable leaving the guys on their own. Mindy dropped by during the installation. Her attentiveness and follow-up were very much appreciated. I wouldn't look further than Foam Engineers for your insulation needs. Bravo to Mindy and the crew of four - thank you for a job well done!

Read the Google Reviews and decided to approach West County Insulation for my historic home re-insulation after water and mold damage. They did a phenomenal job talking options with me for eco-friendly and something that would allow the home to breath appropriately. Could not beat the price and level of service and professionalism. Used them for cellulose batting and blow-in for the attic spaces beyond the bedroom walls. Cannot recommend them enough.

Sahar Joakimβ˜…β˜…β˜…β˜…β˜…2 months ago

I am so glad I contacted West County Insulation for a second opinion. Brandon S had great communication, so friendly (but not tooo friendly). Super professional, intelligent. Was he a sales person? Felt like he was just there to take photos and explain how to make my attic insulation more effective. I'm hiring the company to redo my insulation (just had to come on here and rave about the sales rep!) I'll update the review if the labor is not fittingly excellent

Caitlind Walkerβ˜…β˜…β˜…β˜…β˜…2 months ago

West County insulation did an incredible job with removing and replacing our attic insulation! They quickly got us competitive a quote and Brandon was excellent explaining the process and working with us to reschedule installation when our electrical work took longer than expected. David and Isaac performed the insulation removal and installation: both were kind, informative, and left the area around our attic and stairs cleaner than when they came! Highly recommend this company for any insulation needs.

Michael came to our house to quote our attic insulation situation. He explained different improvements we could take and explained the current situation up there in a way that made sense. His quote was very competitive and his scheduling was even more competitive. They installed without any issues. If you want a knowledgeable professional to look at your attic with a hard working, small company team, this is the one for you.

Corey came out to give us a bid, and gave us a great price to closed cell spray foam our pole barn. We were very picky compared to most customers due to our foam being the finished product inside the building. Corey sent out Shawn to finish out a few punch list items, and we are very happy. There are a lot of contractors that will ghost you when small things need to be fixed. That is not Capital Foam. Corey stood behind his product, and in the end made it to where we were 100 percent satisfied with the finished product. Highly recommend. Great pricing, quality, and they stand behind their work.

This is the third home I've had done by Aladdin and it was wonderful as usual. They put an additional amount of insulation in the attic and brought it to r49. They added insulation to the garage. They also spray close cell phone insulation on the sill plate in the basement in my house I can already tell seems to be warmer. Another wonderful job!

It's a small area but they left spots open so it's easy to maneuver. Offered me coffee, bathroom, water, or if I needed anything else. Hope I get to deliver here again.

Their phone message also reflects this so you can call ahead to check. Hope to save you a trip. Will change the review when they accept again.

Foam Products offers recycling for styrofoam packing materials and coolers, which is a much-needed service here in St. Louis. They make it so easy, you can drop off your recyclables in their convenient bins 24 hours a day. The bins are located around the side of the building. They do not accept styrofoam peanuts or food containers.

I just had the pleasure of working with Corey from US spray foam rentals. He was extremely professional, on time, knowledgeable, and their equipment was superb. I sprayed a 5000 s.f shop for 1/2 the price of using a contractor and the closed cell foam not only insulates but adds structure and rigidity to your building. If you don’t mind getting your hands dirty and like saving money then I wholeheartedly, absolutely recommend U.S. spray foam rentals.
