"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."

"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!"

"My insulation project was more difficult than is typicaly expected, access to far corners of previous insulated attic. 805's crew was successful in insulationing previous overlooked area's. I am experiencing 4 - 5 degrees more warmth this winter reducing my heating costs 15 -20%. John S. SIMENZ & COMPANY CONTRACTING SERVICES INC."

"Joseph and his team were all so helpful and educated. My home was very hot upstairs even with the AC on. After E&E Insulation finished attic cleaning and installing R38 insulation I feel such a big difference in the temperature. The temperature stays the same throughout the whole home. I don’t have to have my AC blasting all day anymore. They saved me so much money on my energy bills. Thank you for everything!"

"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!)"

"This business is great to work with! They showed up early and got right to work. They laid down protective plastic as we have blown insulation that gets everywhere. They installed attic and subfloor. I thought they would be here all day. They were down in about 3 hours. Quality work, professional and very informative and clean!"

Insulation questions, answered by experts

Yes, guiding choices between open-cell and closed-cell foams based on needs.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.
