"Very friendly and quick service. Installers were a little late because they got lost. Very satisfied and notice a difference having new insulation within a couple of days. Highly recommend."

"I am so very happy with the work Larry and his wife (aka Larry's Boss") did for me. I had bugs coming into my bathroom from the attic through the canned lights and ventilation fan. Larry sucked out all of the old insulation (which was at about half the thickness it should have been), the bugs, and a generous amount of mouse poop. He then sealed everything up to prevent anything else coming in from the outside and around the fixtures and blew in fresh insulation. It was AMAZING to walk into my bug-free bathroom and experience WARMTH instead of the insane coldness. They were protective of my home and belongings, punctual, friendly, and efficient. Once I get the wasp nest out of my other attic space, he's coming back to seal off the "entry way.""

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

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.
