"In July 2024 I hired Insulation Labs to add more insulation to our attic. They showed up on time with a truck full of insulation, and a few hours later they had put all of it inside our attic. They did a good job up there. I am very pleased with how everything turned out. One thing that distinguished Insulation Labs from some other outfits is that they did not try to up-sell us with services we didnâ t need."

"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"

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"I wanted insulation blown in above the ceiling of my condo to lessen the noise from my neighbors above. Darren was very responsive and professional and knew exactly what I was looking for. The crew arrived on time, was very nice, and covered the house in plastic sheeting to protect everything from the incredible amount of dust created by drilling dozens of holes in the ceiling to shoot the insulation. Their subcontractor Robert arrived the next day to repair the holes and repaint the ceilings. He also was able to install can lights in my living room (separate job and quote from the job Attic Construction was doing). During installation of the lights, we discovered that some of the cavities that should have been filled by new insulation were not, due to a problem with the old insulation. One call to Darren and the insulation guys showed up early the next morning to take care of it. Robert the drywall guy and his helper Carlos did an amazing job repairing all the holes, you can't even tell that my ceiling looked like swiss cheese at one point. The reduction in sound coming from upstairs is noticeable due to the new insulation and I love my new lights. Be aware though that a job like this is incredibly messy and dusty but Attic Construction OC made it as easy as possible."

FAQs for insulation service projects in Covina, 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.
