Kasi is a local, family-owned and operated spray foam insulation contractor. We service Phoenix, Tucson, Prescott, and northern Arizona. Two brothers, Patrick and Paul Kariniemi, founded Kasi in 2010. Prior to starting Kasi, Patrick spent ten years with a spray foam roofing company in Phoenix and Paul was an industrial construction contractor in Minnesota. Although we’ve tested nearly every foam insulation product available in Arizona, we’ve only purchased foam from a few suppliers. We have an 11-year long relationship with our injected foam manufacturer and a five year long relationship with our spray foam supplier. Since each foam insulation product has its own application characteristics, we’ve found that you have a lot fewer problems by sticking with reputable manufacturers who stand behind their products. As a result, our technicians are experts in the products they install.\n\n

"Darwin came out to give us a quote several months ago. Due to some framing issues, we just now needed insulation. When Darwin first visited my husband and I, we were both very comfortable with his level of knowledge and his honesty. We had some other quotes, but we felt Marshall Insulation would do the best job. Foam insulation is something you do NOT want to trust to just anyone. You need people who know what they are doing. Marshall Insulation knows what they are doing!
They came out when they were supposed to show up and sprayed the house for about 1.5 days. Darwin came out after they were done spraying with his heat gun to make sure all of the foam was thick enough. He had the spray rig come back out the next day to hit a couple spots that were not up to Marshall's standards. I discovered one other little spot in a closet that was a little thin, and Darwin sent someone right out to fix it.
Our house is now extremely well insulated and soundproof. We could not be more pleased with the work that Darwin and his team did. Thank you Marshall Insulation!

"Can't say enough good things about these guys. I had them insulate my garage. They not only do insulation but mini-split air conditioners as well. It has completely transformed my garage space. With our new mini-split it is now nice and cool in there. Perfect for our home gym. Their guys were friendly and efficient. They answered all of my questions. Took before and after pictures in my attic so I could see exactly what they did. They cleaned up after themselves and their price was better than anyone else I could find. I highly recommend them!"

"This outfit is absolutely professional. You really needn't shop around for any other insulation contractor. I'm typically very stingy when it comes to handing out accolades but this company has earned them."

".The work was good but took 2 days to complete due to the availability of his assistants. The process is extremely messy however and suggest you cover everything when the job is being completed. He was very courteous and through. Make sure to mention if you are a senior as he gives a discount. This is a young company and privately owned so Shawn is eager to make you happy. My house is approximately 1480 sq ft and the other quote I received was for $500.00. That was only for the blown in insulation and not all the AC duct work repair."

"What I was hoping to do didn't make sense so I'm pursuing a do it your self option. I spoke to Jeff Banker personally and he was very helpful, told me my idea didn't make sense since spray on insulation generally looks kind of messy and only makes sense for locations that aren't normally seen. He offered me other ideas and one was simple and easy enough that I'll just do it myself. I will keep him in mind though if/when I decide to spray foam elsewhere in my house. Thanks!"




Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
