"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result."

"Good company to work with! They were very nice and seem to be honest over the phone as well. They came on time and did the job. My A/C system didn't work good and a strange smell came out of the ducts when I turned the A/C on. 
Jose that did the work, checked everything and connected a machine to the system letting it run for a while and added a cleaning chemical that made this smell gone.
I will hire them for the future. it was a hassle free with this company.

FAQs for insulation service projects in Big Bear Lake, CA

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.
