"I called and spoke to Luke about his company, and what he could possibly do to my house to make it more energy efficient. He sent out 2 very nice guys, who did a survey of the house and came up with some things they could do to greatly improve the efficiency of the house. He hooked up some kind of vacuum seal on the front door, and showed me how much air was leaking around the house. He looked at the attic to check the insulation, and it was deficient as well. Sean sent me a very detailed report, with pictures, and gave me his suggestions along with the prices. He also told me that he would file all of the rebates for me (which helped take care of a chunk of what it cost). I haven't received a utility bill yet, but can already tell the difference in the house when I turn the furnace on. I think the house is pretty tight! I had them foam the rim joists in the basement, did the whole home air seal and added much needed insulation. A KCP&L inspector came by when they were almost done, and checked their work. He said that he's very familiar with the company and they always do a great job. I was very impressed, and would encourage anyone that is wanting to save money on utilities and have a more energy efficient home to contact them. They were A+"

"This company was absolutely amazing to deal with not only were they way cheaper than anyone else we had bid the job They did way more than expected. They sealed everything up with closed cell spray foam. And even installed two solar fans. Along with the blown in insulation We can already feel the difference after only having this done a month ago"

"The company was efficient and communicated well. I had several opportunities to check every area they worked on over and didn’t find anything they missed or skimped on. I went with their wet blown cellulose for my interior walls. It dried quickly and remained in place for a few weeks until my drywall went up."

"A sole proprietor business, Green Star provided a very competitive itemized written bid. Stuart was very accommodating in considering old (>100 years) home challenges and discussing insulation options and solutions. Promptly arrived on scheduled date, his team was diligent in adding blow in insulation to attic and exterior wall space, as well as foam to basement sill plates, all in one day. Very friendly, knowledgable, professional and unobtrusive in providing their services."

FAQs for spray foam insulation projects in Saint Joseph, MO

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.
