"Geovany and his team did an amazing job at my house cleaning attic removing all debris lid insulation, sanitizing and air sealing attic, installing new insulation and radiant barrier. Job was done in a clean and professional manner. Team was polite and professional. I would recommend Fibers Insulation to anyone looking to upgrade or replace their insulation or just looking to add radiant barrier to their attic for a cooler more energy efficient home."

"The professionalism and quality that the Insulation Labs team demonstrated from beginning to end should serve as a Master Class for any other service oriented company. Scheduling the estimate was effortless with clear, helpful and efficient communication from Diana, their first line of contact. Abraham arrived to do the estimate visit with kind patience and knowledge. He took the time to help us figure out how best to approach the insulation and was more than willing to answer all of our many questions. When we received the estimate we were appreciative of how easy it was to read and understand what the plan was. We knew exactly what to expect and how much it would cost. Today was the day of the insulation. Chris, Tzoc, and Moises spent a long full day doing the entire job. Throughout they were kind, professional, and did an outstanding, neat job. At all times, they cared for our space as if it were their's. We are so glad we chose Insulation Lab. There is no question we would recommend them to anybody."

"Pro Service Insulation did a great job on my project. When I started getting quotes for my project, every other company was two weeks out just for the quote, but not Rob Arnold and his crew. Rob showed up the same day and provided me with a quote, and his crew came out the next day and finished the job at a fair price. Everyone that I dealt with for my project was honest and respectful. I don't know what else to say except the finished project is exactly what I expected. good job guys, thank you."

"The guys did a great job, cleaning up the old insulation and then reinstalling new insulation. They were professional and cleaned up after. I would recommend them."
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.
