"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!"

"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.

"My old door insulation was getting ineffective, and I contacted Reliable to do something about it. It only took them about an hour to come to check it out and have it replaced. My house is now much warmer."

"

I had water damage in my garage from a leaking toilet and the drywall and insulation had been removed by another vendor.  I needed to replace the drywall to the original specifications.  I called 5 contractors from Angie's List and got proposals from 3 contractors. 

We decided to go with Ciro Mejia for the following reasons:

1.  Ciro called me back 30 minutes after I left him a voice message and I was able to schedule him to see my garage the next day.  The other contractors were not as responsive to me.

2.  When we met with Ciro he was able to immediately access the scope of work and gave us a verbal proposal and he emailed me a written proposal when he said he get it to me.  I liked his responsiveness.

3.  When another contractor suggested using mold resistant drywall, I called Ciro back and he said he would use mold resistant drywall for the same price he initially proposed.

4.  We liked Ciro when we initially met with him, he was on time and we could tell that he knew about drywall.

5.   His proposal was the lowest of the 3 proposals we received.

Overall, we thought that the quality of the work performed by Ciro's crew (Cireo, Elmer, Roberto and Benny) was excellent.  They arrived on time and finished the installation of the drywall and plastering in 1 day.  After the plaster dried for 1 day, the painter came by the following day and put primer and paint on the drywall that matched perfectly the rest of the garage. 

We would definitely recommend Ciro and his crew.  Ciro is the "King of Drywall"!!

"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

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.
