"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."

"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."

"Met Mike, had a nice visit on my front porch. I accepted his proposal and his men came to install the insulation. I made a pathway for his men s access, showed them the area to be done. A few hours, they were done. They cleaned up after themselves."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"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!"

Insulation questions, answered by experts

In Orange, insulation success depends on selecting materials that resist heat, pests, and meet local fire safety standards. Proper air sealing and balanced attic ventilation are essential for energy efficiency and moisture control. Quality installation by experienced professionals familiar with local codes ensures long-term performance. Regularly inspecting for signs of moisture or pest intrusion helps maintain the effectiveness of your insulation service project.

Helpful?

New homeowners in Orange should prioritize upgrading attic insulation to at least R-38 for optimal thermal performance during hot summers. Next, seal and insulate ductwork, especially if it runs through unconditioned spaces. Add insulation to exposed pipes and water heaters to prevent heat loss. Weatherstrip windows and doors, focusing on areas with direct sun exposure. For older homes, assess wall insulation, particularly on west-facing walls, to improve overall energy efficiency.

Helpful?

When planning insulation service projects in Orange, consider CA’s strict energy efficiency and fire safety regulations, as well as possible permit and HOA requirements. Take advantage of local utility rebates and financing options. Opt for low-VOC, fire-resistant insulation materials to address air quality and wildfire risks. Plan around seasonal weather patterns like the marine layer and Santa Ana winds, and be aware that contractor availability may vary throughout the year.

Helpful?

In Orange, create a seasonal routine by inspecting attic insulation each spring for settling or rodent activity, and clearing soffit vents before hot weather arrives. During summer, use a thermal camera to spot insulation gaps and monitor attic temperatures. In fall, check for wind-driven debris after Santa Ana events. Winter is ideal for checking pipe insulation and identifying drafts, helping maintain energy efficiency and indoor comfort year-round.

Helpful?

For insulation service projects in Orange, start by booking a professional energy audit to identify areas with poor thermal performance, especially in attics and crawl spaces common to local homes. Check if permits or HOA approvals are required for your neighborhood. Choose attic insulation materials rated for high heat and low humidity, such as R-38. Apply for utility rebates early, and schedule work for spring or fall to avoid peak contractor demand.
