Hey Koala just removed the old Cellulose insulation that was in our 50 year old house and replaced it with “White as snow “ blown in fiberglass that is 20 inches deep. It looks fluffy, but like one of the installers said, “ you would not want to roll in it”. This company and its people are friendly & professional, all well trained in customer service… Great communication from start to finish, I will be telling all my friends about Koala. Thanks from, Dan&Vicki - Stilwell, Kansas 11/19/25
What a wonderful experience! Excellent communication and overall a very professional outfit. They jumped on our project very quickly and left our 20x30 out building looking great! Would highly recommend Koala.
Great experience with Koala Insulation! They went above and beyond to do old insulation removal and new insulation placement, answering questions, and addressing special circumstances in my attic. The time between providing estimate and project completion was smooth and expeditious. Appreciate their excellence! Five star rating!

Our fireplaces look outstanding! In addition to the good results, Miri was a top notch guy to have come provide the service. From start (call to schedule) until Miri finished the job/ it was EXCELLENT! Thank you!
Our gas fireplace was here when we moved in and it was ok but at the end of last season, it would not come on. I called Hayes and the lady that took my initial call was great and got me scheduled on the first call. Julio came out, quickly diagnosed the problem and made the repair. He also cleaned it up, painted the floor pan and replaced the "logs" and embers. It works great now and looks like brand new.
First, many thanks to Dan, who really listened to our needs and captured key details in our proposal. Next, Brian and Ben worked on our attic insulation/re-insulation project. It is a very large space with several unique features. They worked methodically and diligently as a team. Both were experts in all phases of the job (air sealing, insulation wrapping, soffitt vent baffles/blocking, blowing new cellulose and extending all bath exhaust tubes to existing roof vents). They were efficient, professional and delivered exceptional results! I also want to mention Jason and CJ who were assigned to build a long walkway the length of the attic to allow easy access from the access point above the garage to the bath exhaust fans mentioned above. They asked for my input, brought quality materials and created a sturdy and safe walkway so we can maintain our home into the future. They coordinated well with Brian and Ben throughout the two-day project. We have used Hayes Insulation in the past and are truly pleased with the overall results this time, too!

The team were very professional in redoing my attic insulation. We started off with a R value in the 19-20 range and ended in the R48-49 range. First they foam sealed all the gaps from the attic to the living floor and then followed it with piping in the new installation. Photos were taken of before and after and provided for comparison and a blower door test was ran to confirm. Would definitely recommend this business. They took great care of my home and picked up / vacuumed all the mess. In February 2025, had them in again to seal the basement and replace the insulation with foam. Again a great job, would highly recommend them for energy efficiency improvements.
Had several quotes for insulating my attic and Green Improvement Consulting came in at the best price. Not only that, they were easy to work with, did a fantastic job, and had exceptional customer service. The crew the day of were very polite and friendly. Couldn't have asked for a better experience. Would highly recommend.
Sean, and the entire team did an excellent job on our home insulation project. They informed me of the options and recommendations in a timely manner, and the work was performed quickly and efficiently. I would highly recommend them.

These guys are the best!! Friendly, on time and cleaned everything up. The most knowledgeable I’ve spoke with. They drove all the way to Tonganoxie and beat there competitors price. I couldn’t be happier. I will be recommending this company to all. They stayed until the job was done.
This company and the guys are top notch! Had them out to spray foam insulate my existing home. The job was tough, had to remove all the metal and old insulation as they were spraying. They were VERY attentive to the property, home and to us the customer! I was asked over and over if everything was looking good & if there was anything I needed changed or different. Not once could I say yes... they were nailing it! Very professional and came in at a very competitive price! Would highly recommend Missouri Valley Spray Foam to anyone looking for this service!
Missouri Valley spray foam is the best. They bid the project in a very timely manner. They made a special trip out before I was scheduled to spray foam a wall so the plumber could place the shower. They showed up early in the morning which gave me the impression that they where eager to get to work. I was very impressed at the effort they went through to keep the job site clean. They took the time to put plastic down to keep overspray off other surfaces. After watching them work it was clear that they didn't have to be babysat. I wish all contractors took pride in their work like Missouri Valley Spray Foam did. They were efficient and communicated very well. I hadn't heard of them and wouldn't have gotten a bid from them if the drywall company wouldn't had said to call them. The drywallers came out to bid my project and just came off a job that Missouri Valley did and they said it was some of the best work they had seen. I was really impressed with their work.

Mason and his team did a great job. I got my estimate done quickly and our insullation was installed for a fair price shortly after. Would highly recommend
Staff was very professional from estimate to service performance. Mason provided a detailed explanation of services that would help reduce heating and cooling costs and improve quality of home environment. He responded quickly to calls or texts to answer any additional questions. Service technicians arrived on time and were knowledgeable and friendly while providing service. An excellent experience.
Derek and Mason and crew did a wonderful job on our insulation and went out of their way getting us plumbers and roofers to do repairs. I would use them again and recommend them to anyone.

A+ Spray Foam of Olathe insulated my attic, and it’s been the best home upgrade I’ve made. My home stays so much cooler in the summer, and the energy savings are already noticeable. The team was professional, quick, and left the space spotless!
A+ insulated two new additions in my home. A Plus Spray Foam in Olathe was there within 24 hours of our call for an estimate. The price was very good. We are grateful to have found a reputable and experienced company that could handle our large project. We would use them again.
A Plus Spray Foam Olathe installed additional insulation in our attic around November 2022. They arrived promptly after I contacted him to assess the attic and give an estimate. The two gentlemen that did the work were on time, friendly, knowledgeable, and able to answer all questions when needed. The payment process was handled professionally. This company is an excellent choice for anyone searching for similar services.

I would highly recommend Insulation Pros of Independence. Pricing was very competitive, service was outstanding. Tanner was very informative and explained everything in the quote process. Showed up the morning of installation which was nice to see. The guys that did the real work, Jostin and Dalton were very professional and explained again all that they were going to do. 5 STAR to the company and these three men for outstanding work. It's nice to see this in our day and age. GREAT JOB!
Dalton and team did a great job. Very professional in their communication and contacts with me. They called in advanced of arrival each time and checked with me during the project to ensure what they were doing was aligned with my expectations. They cleaned up everything before leaving. It was a big job and I'm thankful they did the work. I would recommend them to others.
Nic came out for the inspection and estimate, he was professional and knowledgable. Dillon and Vaughn did a fabulous job and i would definitely hire them again. No funny business here, honesty and communication with details were appreciated. Thanks guys!

InsulUSA did the job at a fair price and in a timely manner (it only took the crew a few hours). Everyone was very pleasant and easy to work with. I highly recommend this company!
The team at insulUSA was excellent to work with- from the initial bid on our new residential construction to wrapping up the attic insulation. Communication was prompt, the insulation team showed up when scheduled, and their work was thorough and top tier. We're very thankful for their work in helping to make our new home comfortable.
Mitchel at insulUSA did our barn. He called back quick and showed up promptly for the bid. Measured things out, got us a quick and very reasonable bid back. They showed up on the day on time and did an excellent job. Super clean work and no overspray. Highly recommend this company and we will certainly use them in the future.
