"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’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!"

"Adam and his team of workers gave me a great deal on replacing the insulation in the attic. We had a leak in one of the fire alarm sprinklers that caused the insulation to be bad and smelly.
We spoke to Adam about the problem and he sent his employee (Luis) to come over and check the problem in order to provide us with a quote.
The quote that Adam was able to give us was very good and we approved the work. He than sent 2 workers to do the job and it was done in 2 days after they had to clean everything in the attic and to try it before they placed the new insulation.

"These guys saved us during the recent heatwave. I looked for days for someone to come help us service our airconditioner, which was working....except for the cold air part. These guys were so easy to get in touch with and they put us on the schedule for the next day. They took a look and the fix was really easy. They serviced the AC, made some recommendations for future upgrades (but made sure to let us know they weren't emergencies) and left us with a house full of cold air. It was one of the easiest home services we've had in our new house. HIGHLY RECOMMEND."

"GC Heating and Cooling, Gustavo Cano, owner, based out of Bellflower, CA. We enlisted their services on Jan 18th, 2016. We had them install central heating and air conditioning to the whole house, had them remove 3 wall heaters and thermostats, and they capped off the gas line going to one of the old heaters. Guys showed up promptly, were extremely nice, polite, and hard workers! They informed us of too much insulation in the attic, said we really only needed 1 layer so we asked them if they could take the extra out and dispose of it and they said yes. They worked non-stop for 2 and 1/2 days and were finished in record time. Excellent work, no skimping on quality! I had them put a vent in every room, they added bigger vents in the living room and the back bedroom. They gave us a state of the art thermostat that I could sync to my smart phone, Very nice! They cleaned up everything so that you couldn’t even tell we had work done, and gave us the name of a patch guy, to fill in where the 3 wall heaters were taken out, and informed us we may have a rodent problem. We took care of that. Gustavo Cano and his crew did an excellent job. Gustavo is very easy going and a straight talker, he didn’t try to sell us anything we didn’t need. I have already recommended them to some of my friends, and would use them again! Cullie R.

When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
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.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
