"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’m extremely satisfied with their service! We hired them to do the clearing and installing for the new insulation in my attic a few months ago. It was very easy to set up an appointment over the phone. Adam, the owner, was very helpful every step of the way. They worked super fast to help install the insulation and disposed of the previous one. Great job and thank you guys!"

"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."

"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

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.
