"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"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!"

FAQs for insulation service projects in Ventura, 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.
