"Nate was really good about returning calls and making appointments for my project. There were a few hiccups (not his fault) because this is a rental property. I would recommend him to insulate a basement with spray foam."

"Very professional, very efficient. They covered everything in the room where they had access to the attic. Cleaned up after the job. They put some extra insulation in and didn't charge extra. Stuck to the original estimate."

"Vista has come to our house, especially a particular gentleman. Really knowledgeable, very professional. They do several different things. I have had them out to do estimates on gutters. We have not hired them for anything. To give you an idea, when they've come out I was very happy to open the door and see it was the same guy that has come several times to do several things. I interview several people. Not only did he come, and it's a little confusing to me because it has to do with ventilation and insulation, and excuse my language but there is a whole freaking science to this thing, but the owner actually came out. Not only did they keep in communication by computer, the owner actually came out and reinforced the whole education and what needs to be done. I was really thrilled with that. I thought that was beyond the call of duty. I am sorry I was not able to go with them, but I would certainly say as far as customer service relationship, excellent. The information was excellent. Not bothered by the fact that he had to come out more than one time for the same kind of information. I've never had the opportunity to hire them. But I've never been disappointed. They will take the time, they will talk to you, they will educate you, and they will actually give you the best price they can possibly give you. I got educated so that when my  husband came home I could explain to him what is going on. I can't rate their work, but as far as their generosity of time and caring, it's off the charts. I don't know about price because this is a whole new area to me. They were amazing. I have to tell you I have had them out several times as I said, it's Vista Home Improvements so they do several things, but I feel kind of bad that I am yet to hire them. I am trying to think exactly where Vista is out of, but for the owner to com about to your house. We're talking about a wrap around attic. We are talking about getting on your hands and knees and crawling around."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation FAQs, answered by experts

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.
