"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"!!

"I can't edit previous review so posting new one: I am revising my previous review. After posting my first review, Danny in Customer Service at Home Comfort USA contacted me. Danny very patiently listened to my situation and frustration and told me he would look into it, but wouldn’t “leave me hanging” and would call back. He did call back and fast-tracked a HVAC technician, Jad, to come out, who was great and called in a higher-level technician two days later. Then the higher-level technician came out a couple of days after that and found we did need a leaking core replaced and said Danny would call me. Danny did call me and went above and beyond to get the part replaced under the manufacturer’s warranty. Two days after that, Home Comfort USA came out, replaced the core, tested our HVAC, and mitigated the labor. We are now VERY happy customers with Home Comfort USA and very grateful for Danny’s great customer service and intervention. I am writing this review on a day in the mid-90s with our HVAC system keeping us VERY comfortable. Thank you."

Insulation questions, answered by experts

If the outside temperature drops below 20 degrees Fahrenheit, it will take around six hours for your pipes to freeze—and they might even burst. That’s why keeping your mobile home’s temperature around 50 to 60 degrees Fahrenheit is necessary, even if you’re leaving it vacant for the winter. In addition, having ample skirting around the mobile home's underbelly will help keep pipes insulated during the winter. 

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

Yes, insulating hot water pipes helps your system run more efficiently. This is especially true in basements in colder climates, where cold air likes to settle in. There are a few ways to insulate water pipes (foam is common) to keep hot water hot, reducing the need for your water heater to constantly heat the water in the tank or your circulator to kick on more than necessary.

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.
