"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."

"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!)"

"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!"

Insulation questions, answered by experts

Cellular shades, also known as honeycomb shades, are the most energy-efficient and insulating window treatments. Their honeycomb structure is made of soft fabric that forms layered cell pockets. These pockets trap air, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even greater insulation, consider double- or triple-cell varieties. Side-tracked cellular shades, which seal the edges of the window frame, can further minimize air leaks and maximize energy efficiency.

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.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.
