"Ivan was prompt and professional. He delivered everything as promised. I would definitely used him again if I ever have the need to do any insulation project I had. His price was reasonable and the work was professionally completed and on time. A good experience all the way around."

"We called Sean with New Found Construction and he personally came out and gave us a quote to insulate our attic and the ceiling in the unfinished part of our basement. His price was far more reasonable than other quotes we had gotten and seemed to offer a more complete job. It all came out AWESOME and we can absolutely feel a difference in temperature in the house (especially my office above the unfinished basement which used to be an icebox in the winter) and the heat kicks on a lot less. We have already planned to have him and his crew do other jobs around our house. Two thumbs way up!!"

"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"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."

"They did not cover the baseboard and there are very fine sprinkles of paint on them.  I had to pay more for them to paint the ceiling, which is fine, but you are still able to see the water marks that I wanted covered.  It is not as bad as it was, but you still can see it."

Insulation FAQs, answered by experts

Insulating your ducts offers several benefits, including:

  • Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.

  • Cost savings: Lower energy bills make insulation a cost-effective investment.

  • Environmental benefits: Enhanced efficiency reduces your carbon footprint.

  • Consistent comfort: Insulated ducts help maintain a stable indoor temperature.

  • Better indoor air quality: Reduced allergens and pollutants improve air quality.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.
