"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!!!"

"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!"

"Me and my husband live in a condo in Los Angeles. About 6 months ago the neighbors upstairs rented their condo. The new neighbors are a family with two kids who are very sweet, but like to wake up early and throw stuff on each other. (At least thatâ s what itâ s sounds likeâ ¦) we talked to a few different contractors, most have offered us to inject insulation to the ceiling. We tried it, as it was not expensive, but, this did almost nothing. My husband who has very light sleep kept waking up every day at 5, what made our life very difficult. We did some due diligence and realized we need a much serious approach. When we talked to Eli at ELM, we understood right away thisbis the right contractor for us. His level of knowledge exceeded everyone else's, and he was wiling to make everything as clear as possible for us. The price wasnâ t cheap, as the construction included demo, installation of many materials and even lowering the ceiling. The project took about 2 weeks and we could see the difference right away. We could barely hear any thing!! What a huge difference! The crew were cleaning after every day of work and were very professional. I highly recommend ELM (make sure Eli is meeting youâ ¦.) for every Sound Proofing project. Thank you Eli (and pedro!)"

"Stephan and his team were professional, on time, priced fair, protected the house well, and the removal of old/install of new attic insulation went very smooth. I requested they spread the work over 2 days in order to have electrical done in between, and they were able to accommodate that request. The electrician commented that they did a good job not disturbing existing electrical during the removal of old insulation. The result of the new insulation is a much more comfortable and efficient home. All in all, I would hire again, great job."

Insulation questions, answered by experts

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.
