"Work was done in a timely and professional manner. Workers very polite. In a couple of places, they did not completely remove the old insulation and just sprayed over it, leaving hanging pieces. Also, the cleanup after the job could have been better. Overall, we are very satisfied."

"I hired Insulation Commandos to remove old and improperly installed batt insulation from the crawl space under the first floor of my home. Matt Rich came to the home. We both went into the crawl space, where he explained what needed to be done. He then ordered new R30 batt insulation of the proper thickness. Two days later, the work crew of Alex and Carson came early in the morning and took down the old insulation, bagged it up in the crawl space, and removed it to a large trailer to be hauled away. They were then joined by Matt and the three of them installed the new R30 batts under 1,000 square feet of flooring and did spray foam “air sealing” around all pipes that went through the floor. The entire job was completed in about 6 hours with no wasted materials. Matt went into the crawl space with me multiple times before, during and after the job to explain the “where, what, how, and why” of insulation. Because I am a “need to see and understand” guy, I really appreciated Matt."

FAQs for spray foam insulation projects in Calhoun, GA

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.
