He's in the top 5 contractors I've had the pleasure to do business with over the last 20 years that I have been in the manufacturing business, maybe my lifetime!"

"I had a great experience with Stephen and Amy recently when I hired them to spray my garage ceiling. They went above and beyond! They were extremely responsive and got me a quote quickly and were able to fit me into their schedule within a week. They ran short of foam, but came back the very next day to complete the project. Amy, Stephen and their team are good people. Please trust them with your next spray foam project. They took extra time to mask and tarp off everything and cleaned up when they were done. I’m extremely happy with their work and will use them again for future projects."

"Fantastic. Redeemer filled all of the voids under the entire driveway - literally at least 1/3 of the driveway had zero support underneath it because the ground had washed away. The Whole driveway is now level and all the cracks are repaired."

FAQs for spray foam insulation projects in Greenfield, TN

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.
