"We contacted ECO insulation because we wanted to improve the comfort of our home year-round. Kris inspected our attic and discovered that our insulation was below where it should have been following the original build and that there were several areas that were not sealed. We were wasting money via our less efficient insulation and energy use. ECO sealed all areas, increased the insulation, and we noticed our AC ran less immediately and kept our home cooler longer on our first 101-degree day. Thanks, Kris. We highly recommend your company and work."

"Streamline installed a garage ventilation system and attic insulation above our garage, would definitely use them again. Great people and service. Happy with the install, had questions a few days later and the representative was at our home in about 30 minutes. Highly recommended"

"Chris was the installer. He spent about 90 minutes blowing in my insulation. He even added an extra bag. Cleaned up afterwards, too. Happy with the job. Can't wait to see how effective it is."

"these folks did blown insulation for me , that went well. The problem I'm having is getting documentation to submit a rebate claim to Dominion energy. Just can't seem to get it right. Haven't given up yet. Also ask about a small gutter fix and was told on its own wasn't worth there time, however if they were in the area on another job it could be. The price I was given was more than a previous job approximately 3 times larger. Same company installed. Little frustrating."

"Good work, fair price. Only complaint is they did not call me to set up an installation appointment. They just showed up one morning ready to install the insulation. It worked out because I was home anyway. I would gladly use them again but I would make sure they schedule an appointment."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"They came when they said they would and did a great job prepping the house before starting. Overall they did a great job with the foam but left several places that were bulging out beyond the studs. When notified about this, they came right out and trimmed the excess away. I would recommend this company."

FAQs for insulation service projects in Saint George, UT

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.
