"We needed an installation installer quickly because we had to rip out existing insulation for electrical work to be done. It was February and getting very cold in the house. Robb came right over to give us an estimate. Greystone came in just four days later and completed the job. The installers, Anthony and Carlos, were excellent, very courteous. They did a very thorough job and did not stop working the whole time they were at the house. Thank you!"

"Not the best, but I guess not the worst either.
They did the door blower test which revealed different air leaks in the house. They sealed around some of the doors in the home, installed some door sweeps, caulked around baseboard registers etc. However, the work was far from consistent and less than professional in quality.
There are 15 registers / returns in the home and we were told they would caulk around them all, they caulked around 7. 2 of which the caulking was so thin that it cracked before the next morning.
There are 3 sinks in the house where pipes were supposedly "foamed and insulated" on their report. There is no additional insulation visible anywhere that I can see.
We are entitle up to 40 CFL light bulbs in the home, however, even the 30 they said they changed were not completed.
For example:
-there are 2 nightstand lamps in the bedroom. One lamp received a CFL and the other wasn't touched.
-there is a hallway ceiling light that was supposed to be changed out with CFLs, but still has the same old bulbs.
-downstairs bathroom still has all three original bulbs
-two bedroom ceiling fans that take regular "A" type bulbs all have the same bulbs
I sent an email to the gentlemen who came out to the house asking if we could at least receive the extra bulbs. He did respond and said yes, but never got back in touch with me. After the general overall experience I did not bother chasing after them for a few more dollars worth of bulbs. However, the whole point is not the money, its the fact that these were all listed on the report and not completed accordingly.
They did recommend an insulation company to come in and give us a quote and also told us about different programs offered from the state which would allow us access to rebates for making home energy improvements. All in all, I guess it helped us to know where the air leaks were in the house, but the overall performance of the team was simply sub-par. They were nice, polite and somewhat informative but by no means "wowed" me.

"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 questions, answered by experts

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.
