"Miguel and Richard insulated the entire south side wall of my house, including my master bedroom. They were very professional, honest and very clean. They walked me through the process so I knew exactly what I was getting. They had the best prices and used all the left over material in empty spots in my attic. I would recommend them to everyone needing insulation work done. Removal and or install. We have remodeled our entire house and they were the most pleasant to work with. Best of luck fellas, god bless. Kevin"

"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."

"I’m extremely satisfied with their service! We hired them to do the clearing and installing for the new insulation in my attic a few months ago. It was very easy to set up an appointment over the phone. Adam, the owner, was very helpful every step of the way. They worked super fast to help install the insulation and disposed of the previous one. Great job and thank you guys!"

"We noticed that some of the ducts are open and leaking air. We contacted several companies but at the end, we decided to hire this company. The price was right to us and they could do it the same week.
The work was completed the same day and they 2 workers that came over, were nice to us and didn't try to sell us anything else.
We appreciate the work and the fast service.

"One of my relatives recommended to me this home remodeling company after he hired them for his house and they were super happy due to the fantastic job that Best Builders did at his home. At my house I wanted a new patio deck built before the summer will start. Sofia from the main office scheduled me an appointment with one of her people and she sent out Zohar, who worked with me step by step through this entire remodeling project. Zohar is a great guy and a professional person! He made sure that everything is being done exactly as it was promised in the design stage AND each change that he wanted to do (in order to make this project better than it should). The new deck including the covers looks fantastic and it came out much better than I imagined. I’m glad to have worked with Best Builders Group!"

"Excellent service and good people to work with! Adam was very generous to us when we contact the office and asked for their help with the problem at our house. The insulation had to be replaced based on an inspector requirements. 
The replacement work took 3 days in a row and the workers did a good job. we will hire them in the future.

FAQs for insulation service projects in Blue Jay, 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.
