"Deli Brothers Insulation came to my home and did an absolutely marvelous job from start to finish. From the moment they arrived, their professionalism was clear—they were punctual, polite, and ready to get to work. Not only did they complete the insulation quickly and efficiently, but they also kept the work area spotless, which I really appreciated. Their team was extremely knowledgeable, answering all of my questions and explaining the process so I felt informed every step of the way. It’s rare to find a company that delivers both top-quality workmanship and outstanding customer service, but Deli Brothers Insulation truly exceeded my expectations. I would highly recommend them to anyone looking for reliable, clean, and expert insulation services."

"I am very happy with the honesty and professionalism of this company. They were going to use the foam insulation in the bedroom, but were unable to access it. They took pictures of the attic space before and after they pumped in the spray insulation. The house is feeling cooler now as we had no insulation in the attic under a metal roof."

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.
