"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."

"The professionalism and quality that the Insulation Labs team demonstrated from beginning to end should serve as a Master Class for any other service oriented company. Scheduling the estimate was effortless with clear, helpful and efficient communication from Diana, their first line of contact. Abraham arrived to do the estimate visit with kind patience and knowledge. He took the time to help us figure out how best to approach the insulation and was more than willing to answer all of our many questions. When we received the estimate we were appreciative of how easy it was to read and understand what the plan was. We knew exactly what to expect and how much it would cost. Today was the day of the insulation. Chris, Tzoc, and Moises spent a long full day doing the entire job. Throughout they were kind, professional, and did an outstanding, neat job. At all times, they cared for our space as if it were their's. We are so glad we chose Insulation Lab. There is no question we would recommend them to anybody."

"I hired Attic master to come over and check the attic for some bad smell. Adam came over to my house and went up to the attic and checked the problem there... He recommended me to remove the old insulation and to place a new one. His price and warranty were good... so i hired them. The following morning, he came over with his worker and took out all the old insulation while his worker placing the new one. The work was completed the same day and the problem of the bed smell has been solved."

"We had no problem or issue with this company. They came and did exactly what they said and promised. The service was fast too. We were able to schedule them for the same week and the work was completed after 2 days of work. According to the technician that worked at our house, it was better to use the opportunity when the attic empty from the old insulation and to replace the ducts as well. For the price that we were able to got, we decided to do that too.
so overall, we are in the stage that we will use this company in the future and we will refer them to people that we know and might need the same kind of work to be done.

"GC Heating and Cooling put in a 3 zone furnace and AC system for our 3100 sq ft house in Manhattan Beach back in 2018. We recently had an issue due to the unprecedented heat wave and Gustavo and Jordan fixed the issue under short notice. You can always expect quality work and great service from them."

"I called several contractors who all quoted me exorbitant amounts of money for a simple, non structural room within our large one bedroom condo. Ciro came and his pricing from the estimate was very reasonable. I called a reference to check to see if his work was detailed and if he cared about the jobs he took on. He came with rave reviews and so I decided to take my chances on him - the folks we had in here before left a lasting impression of "what not to do" so I was skeptical. We had to delay the start of the job due to Homeowners Association approval and Ciro checked in every few weeks to check in. He looked at the picture I drew and said it was no problem to create my vision for the room - after all, our baby had been sleeping in the living room - this was going to be her room. He was right there with me. When we finally got the room approved by the association, I asked if he could start that following Saturday. He did - on time and followed all the association rules for working/noise, etc. He even dealt perfectly well and calmly with a crazy neighbor we have on the first floor. He got the room up in a day using metal studs and then sound proofed the room with sound board and insulation. He then put the dry wall up and took care of all the electrical within about 5 days. By the Wednesday of the following week - everything had been pretty much done. He painted, installed the crown/base molding and finished off the recessed lights. He installed the chandeliers and smoothed out the prior popcorn ceilings we had scraped when we moved in. He was fast! What I truly loved about Ciro and his crew was how meticulous they were. Every little detail was covered and the pride and passion that went into the work was amazing. He sanded every crevice and didn't rush the finish or the detailed work like so many builders do. Ciro even came back after we noticed a smudge in the paint and fixed it - no questions asked - he was glad to do it. His sister even came when the project was done to clean up the place from the drywall dust and they did a whole house cleaning (bathrooms and all). I have never been more impressed and when my wife returned to see a put together condo with a new room for the baby - she was thrilled. We can't thank Ciro and his crew enough - the baby now has her own room and we have our lives back after 7PM :) If anyone has any questions, they can feel free to contact me - I will always be a reference for Ciro. A great guy with a great crew who truly loves what he does and always has a smile on his face. What a great experience!"

"Mario is an amazing technician! He came to my home on time, was professional, courteous, and knowledgeable. The visit was only for a maintenance of my heating and AC unit, but Mario noticed some concerns with my insulation. He took an immense amount of time to explain to me the entire process of how they will clean out and replace the insulation. I was extremely satisfied with the service provided. Mario really embodies the core values of Home Comfort and went out of his way to make sure that I was comfortable with the plans being made and that I was happy. He also worked out an amazing deal for me on the insulation project. He is the best technician and I left feeling that I am a valued member of the Home Comfort family. Thank you, Mario!!!"

Insulation questions, answered by experts

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.
