"I hired this company tell help with an insulation project. Joe arrived when he said he was going to, he is an extremely hard worker, and the job was completed in a timely manner! 100% recommend. I plan to hire this company again in the Spring for a deck building project and I?m really looking forward to having Joe back. He is kind, reasonable and I have nothing but good to say about him and his work."

"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."

"The gas company came in to replace a meter.  They found that the vinyl siding company we used in the past had cut and covered the safety valve.  The one night that it's super cold out, the gas company had to shut off our gas (heat)!! I called Richard at 9:00pm.  He got back to me first thing in the morning and had his crew take care of it by 7:30am.  They are really THE BEST!!  The gas company is here now and hopefully we'll have heat soon."

"We have had an intermittant water problem in our basement primarily when it rains heavily in the Winter.
I was very happy with the quick response from Mike Sears when we initially called to ask about repairing a water leak problem in our basement.  Mike explained how his proposed solution would work to alleviate the water problem. 
Mike left us with a detailed estimate and informational materials about the proposed repair.  He also explained what wasn't included in the job such as tearing out the current sheetrock, insulation and framing from the wall.  I did  this part of the work and the reconstruction after the drain had been installed.
We spoke to Mike a few days later, agreed to the price and set a date for the repair.
On the scheduled date, two of Mikes employees arrived on time and began to prep for the repair.  They did a good job of hanging plastic sheeting around their work area so that the dirt and dust would not get into the rest of the basement.
We had discovered a crack in the basement wall which wasn't visible when the original estimate was given.  Scott Lee gave  us a written estimate to repair it with carbon-fiber cloth and sealant.  While this was an unexpected expense, there was no reason to put in a drain and leave a crack in the wall.
Taking out a basement floor with a jackhammer and installing a drain is a hard, dirty job.  Scott and his co-worker completed this job in about 6 1/2 hours including the additional work for the wall crack.
They did a good job of cleaning up the old concrete and all working materials 
Scott explained how the pump would work when the water table under the house rose.  
My only issue with quality was the uneven concrete finish work on the basement floor above the drain.  Because this was leveled by hand, there is a somewhat noticeable depression in this area of the floor.
Overall, I am happy with the work and looking forward to a dry basement when the rains come this spring.

Insulation FAQs, answered by experts

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.
