Kasi Home Komfort Engineers

I had a very good experience with Dustin and his team. Thanks to his leadership, I was able to finish my project on time.

The installation was grea!. The prep team set everything up prior to starting and then cleaned up after they were done. You could not even tell they had been here other than the walls in the ceiling room how much cooler in the garage? The technician that did the injection was thorough and very competent when he did his work. I would recommend Kasi to anybody that needs any kind of insulation work. Professional!!

Ian and Abel were professional, friendly and quick. Not only were they very friendly but they also they did great work on top of answering all my questions.

Thanks again.

Professional, consciencious, and courteous the entire way. Our 6,700 square foot home had the blown in and batt insulation removed and then open cell foam installed. What a remarkable difference it has made to the comfort of our home.

Dustin and his crew did a great job. He came over the next morning to make sure everything was good and cleaned up a few spots they missed the previous day. Customer service was outstanding.

All of the best experience you’d like from a contractor! Great communication, careful preparation, attention to detail, and meticulous cleanup. Great job, Dustin!

Kasi was the only company that came out to bid on my job. I was impressed with how much detail and work went into the bid itself. Then the crew actually showed up when they were supposed to and did a great job of prep, execution and clean up. Then I noticed a couple of areas that required touch up and they were back out within two days to make good on the repair. Dustin their team leader is a solid guy and is a pleasure to work with. He makes Kasi the great company to do business with what it is!

We had the foam installed on part of the south and east facing part of our house (garage being on the west). We also had insulation from another company added to our attic. It is cooler, but I'm not sure which was most effective. We haven't seen a reduction in our electric bills, however that's hard to gauge due to inflation. I plan on hiring them to do our casita when we are ready since we do not want to drywall.

They were very kind and flexible with our ever changing delays (yay construction!). They kept everything very clean and I’m shocked how much cooler the house is even though we don’t have the AC system installed yet. Thank you!!!

Came out for a quote.... but could not explain how many sq feet the 1600 minimum would cover. Then takes very rough measurements. And can not answer any questions on how much temperature change or what the benefits of them doing the insulation. Better look to the next company. These guys were not very impressive. The sales guy was mad I was asking questions. Like I should just pay and assume the job would be done correct. Owner of the company was also not willing to come to the home and give me a more accurate estimate.

My adventure of finding the right spray foam company happened after our fluffy insulation got into our attic air handler drain and clogged it-causing an overflowed drip pan and ultimately a huge leak in our ceiling. This led to a massive repair and paint job. So we looked into multiple companies. I chose Kasi- but ultimately we decided once we got a new roof, then we would get spray foam. About 2 years after the initial, we had gone thru another clogged drain in the air handler (not leading to a leak), we got our roof. Then we contacted Paul and Patrick for our spray foam. They re answered a lot of my questions and even worked with our roofer team to make sure we got everything done for best insulation. They were so nice, even remembered our house. They sent their team, who took their time and was thorough.... they pay by the hour and not by job, btw. Kasi gives you a sensor and a thermometer to monitor your attic which should not get more than 10-15 hotter than your house. We did this in January 2024. The team accidently knocked our nest wires out, so Kasi sent their own AC person over to fix the issue and they didn't bat an eye at paying to do so. They are honest and have integrity.

We were displaced due to sewer in Feb 2024 for 3 months. We didn't need to run our AC at all while we were gone. The spray foam kept the house temp excellent even for all of the remodeling and reconstruction. Since being back, not only is our house cooler, and our AC bill down, but it's so much quieter too. WE JUST LOVE IT. 12/10 would recommend Kasi to everyone.

Kassi put foam in my existing walls of my house as well l as my garage. I am beyond thrilled with the end result as well as their customer service throughout the entire process. I am also doing an addition to my house and will be calling them to do spray foam when I am ready.

very profressional and prompt from start to finish. Joe and his team helped spray foam my interior walls, and couldnt be happier with the result. Thanks!

Great company that does a fantastic job! Paul came to do my estimate and was extremely friendly and explained everything clearly. Went through the pricing with me and made me feel comfortable with choosing which option fit me best. No hard sales pitch at all. Then Dustin and the crew showed up to do the job right on time and were just as nice. They worked quickly and did a quality installation of Retrofoam in all my block walls. I highly recommend this family run company for all your insulation needs.

The team at KASI Spray Foam Insulation was outstanding! From start to finish, I was overjoyed with their service and expertise. Peter arrived for an estimate and to discuss the scope of the work. He was kind, respectful, and extremely knowledgeable. We discussed different price options and timelines for the garage and the house. Less than 4 hours later, there was a complete detailed estimate sent by email. Peter followed up with a phone call to see if there were any unanswered questions or concerns that I may have. The two-person team (sorry, I forgot your names) arrived on time and ready to work. They proceeded to work and were finished with the garage in no time. Before leaving, I asked them to look at an additional storage (attic) space for advice. Upon accepting their advice, they called the main office to add to the scope of work. Within seconds, the central office had adjusted the scope of work, and the men proceeded to do the additional space. Upon completion they cleaned up everything and left no trace of their work. I will call KASI again for work in my new home. THANK YOU!!

I am a 3rd time, repeat customer of Kasi foam insulation services provided in the Phoenix metro area. This last occasion was performed to a high level of excellence by the team that included: Removal of prior Attic insulation, replacing with Attic Foam Insulation, Cavity Wall insulation for interior and exterior walls. They were reasonable in addressing complexity and provided excellent pre and post sales support. I cannot recommend the company and the team enough for all needs and to help with the Arizona heat and rising costs of cooling. Well done.... Great Job and will use Kasi again, no hesitation!

Kasi did a great job on my water tank years ago. Much cooler water and no algae in water now. I recommend kasi for any installation work work that is needed.

Kasi foamed my walls and attic in my new build, I couldn't be happier with the quality of work and professionalism. This is the first house I have lived in with foam as my insulation and does makes a huge difference with comfort and costs. Highly recommend.

We used Kasi foam insulation on an interior room and garage roof. The installation team of Joe and Dustin did an outstanding job. On time, clean and delivered a thorough job.

Finding a company to not only provide a stellar service for my shop project, but also with a notable reputation and reasonable quotes in tow seemed next to impossible until Kasi was highly recommended by a family friend.
I cannot express enough how thoughtful and thorough Patrick and his entire team were. From initial contact with the owner, to the timeliness of Dusty, Joe and one another gentlemen. Very impressive group of fellas that spoke highly of the company that they represent.
Bottom line, the proof was in the pudding from beginning to the end.They are a true asset to the company and their professionalism exceeded my expectations. From the moment that they showed up to the cleanup process. The Picassos in the this world if you ask me, they worked incredibly hard with every step and motion and it ultimately resulted in a very clean job!!! I am over the moon about the entire experience.
I will happily and highly recommend/use Kasi Home time and time again. My thanks again to Patrick for taking care of me like I was family. I appreciate you and the fellas greatly!

Käsi Foam went above and beyond my expectations. I needed to have the interior roof deck of my shop foamed, as the interior during the summer month were typically 10° warmer than the outside temperature. Joe and Able came early in the morning and prepped my shop, covering floors and walls and a couple of pieces of equipment that couldn’t be moved. Dustin came in and sprayed the roof deck and the gables which I didn’t expect. They were in and out, in under 5 hours. Very professional, courteous and clean. I very much appreciate them and the work they did and highly recommend Käsi Foam.

Patrick was exceptional in the discovery phase as we looked to remove old insulation from the attic and replace it all with 6 inch foam that adheres to the inside ceiling of the home. The idea is this would keep the attic about 10 degrees warmer than the temperature of the inside of the home. The crew that removed the old insulation were exceptional, clean, and very professional. Then the foam insulation spray was completed by Dustin who absolutely knocked it out of the park. He is very professional, clean, thorough, and calm the entire time during the one day of foam spraying in very hot temperatures. But if I had to call out one more thing Dustin was extremely courteous. I am going to pound the tables here and recommend this company to anyone looking for a better home insulation solution. After just two days we’ve noticed that the house stays cooler and the AC unit is working far less to keep the temperature steady at 71 degrees all-day. Amazing team and company. So thrilled we went with KÄSI.

We bought an older (1976) Phoenix home two years ago and became concerned about high temperatures in our garage during summer heat. (Friends told us that garage temps can exceed 140 deg F). We were lead by several positive reviews to KÄSI Spray Foam, a family-owned contractor in Phoenix.

We were absolutely pleased with every aspect of the job. Paul Kariniemi explained the process of removing and disposing all of the old rock wool insulation on the attic floor then blowing spray foam on the underside of the roof, injecting foam into the hollow centers of our cinder block walls and then lining our garage walls and door with 1-1/2” foam panels.

I placed a recording thermometer in my garage for the summer of 2021 and the temperature in the garage never exceeded 90 degrees.

The KÄSI team was on time, they were clean, and they met their cost estimate. I rank them at five stars plus.

They worked very very hard, professional crew, and worked well with my contractor. The house is noticeably cooler! I would recommend them to anyone!

Had our house sprayed at the beginning of August. Before the foam was installed our house had hot flashes for a couple hours as the sun was setting and temps would not fall below 81 degrees. Our daily usage was around 11$ After the foam was installed temps dropped to 73 degrees ( which is what we has the thermostat set at before and after) and the heat flashes dissapeared. Daily usage is now around 8$ well worth the investment.

We wanted to give a big show of thanks and appreciation for KASI Spray foam installers.
This is the second home they have been able to correct our heating and cooling issues for us. The first home had hot rooms that were unbearable to be in in the summer. They filled our walls with retro-foam and the problem was solved.

Our new home was having a cooling loss issue. They came and assessed our problem. They ended up vacuuming out the inadequate celulose insulation from our attic. Then they sprayed foam in our attic, which made a huge difference the first day. It lowered our cooling costs immediately.
The workers were very diligent and committed to their job. We can’t give them enough praise. The attic was very hot while they removed the old insulation and sprayed in the new foam. They earned their money.

Kasi left us with a monitoring system that shows our inside house temperature and the temp in the inside the attic. The gauge says outside temp but it is referring to the attic temp. It is just as they guaranteed 10 degrees or less difference.
Attached are some pictures taken July 17th 2019. The hottest day of the year so far 113 outside, 87 in the attic and 79 in the house.

We are very happy with Kasi. They do what they say they will do, they don’t try to sell you more than you need, they meet their guarantee, and we would recommend them to everyone.

They are a company you can trust, and know they won’t be cutting corners when your’re not looking. Very high integrity in our opinions.

We used KASI in a commercial building and found them to be very professional. They were especially accommodating, as they had to work around another trade. They arrived promptly, kept their workplace neat, and completed their work in a timely fashion.

Other than the fact that we have seen zero reduction in energy costs as promised, after a recent camera install that required getting into certain parts of the ceiling that we can not see otherwise, we noticed the following.
In ceiling speakers were not covered and now have overspray which likely effects the quality of the sound. Also areas that are clearly foamed, compared to areas that clearly did not get any treatment.

Now that several years have gone by since Retrofoam insulated my attic I can really attest to the benefits. First, my power bill has decreased by one-third! Also my A/C does not cycle on and off as frequently. This is great! And an unanticipated benefit is just how useful and pleasant it is to have a clean and climate-controlled attic. Retrofoam did a great job, and I am a very pleased customer.

They came to our home on time. They did an excellent job. We had some siding installed by a "handy man" a couple a years ago. Retrofoam noticed that they had not adequately screwed down about half of the siding that was installed. They fixed it for us at no additional charge. The man that came was very courteous and finished the job within the time he said he would. Our home is cooler in summer, and warmer in winter. Plus, it is quietier as well. We are very happy with the work they did and would highly recommend them to anyone who wants to make their home more energy efficient.
