"So far very good. Itâ s just completed hopefully this will make a difference. Feel good about having the old insulation removed after 38 years. Old insulation was breaking down like sawdust. Attic is clean now no critters or bugs to worry about. Everyone was professional & efficient. Ask again in one year for an update on performance & customer service if needed."

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

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.
