"He was in contacting with me by text letting me know he will be arriving at my home. He was on time and no waiting to show up. He asked for the garage door to be open and up dated what the issue was. Missing insulation over master bedroom he went directly to the attic and I followed him. He was very professional in letting know that there was more than that area that needs insulation."

"I did a lot of research when I decided to Spray Foam my home. I also researched several companies. Green Energy exceeded my expectations and then some! From the office staff, customer service, the technicians, and beyond, I can honestly say this company is the best company to work with. They went above and beyond and you can tell, not only are they extremely knowledgeable, have tons of certifications, experience, and accreditations, but they really all love what they do! It shows! I would highly recommend using Green Energy for any spray foam insulation project, regular insulation project, etc. Also, if I could duplicate the staff for my own business, I would! Best Rated Company! I give them 10 stars!"

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.
