"We had our entire finished attic space insulated (walls, ceiling, floor of crawl space). We did this primarily for summer, so the air conditioning would actually work in the room (it was still too hot to inhabit last summer even with a massive air conditioner running constantly in it). It's still winter time, so we haven't been able to test it for the air conditioner, but we have noticed a difference in our heating. The mini-heater we have up there runs much more infrequently and the heat stays in the room much longer. So far it seems like they did a good job, but I'll definitely know when summer gets here. We opted to stay in the house while they installed the insulation (some of which was the spray foam). Craig made clear that it is highly recommended that the residents evacuate the home while the foam is being sprayed, but we couldn't leave our dogs there alone and I was working from home that day, so we opted to sequester ourselves on the first floor in the back room, which worked out just fine. I mention this because I assume most people wouldn't be home while the installation is occurring, but because we were we heard a lot of the banter that the crew was having. There was some yelling (in a friendly sense) between them, and we heard a bit of profanity. It didn't bother us at all, but if there are children in the home and you opt to stay inside during installation, keep that in mind. I have a feeling that if we had asked them to try and lower the volume a bit, they would have respectfully obliged. The crew was friendly and seemed to be very competent and knowledgeable. The crew used big rolls of plastic to cover the floor/stairs/furniture while working, so they try to make as little imprint as possible which is nice. There was some plaster dust and insulation left over in very small amounts on the floor and couch in the attic, but I attribute that to the fact that it's virtually impossible to prevent anything from touching the floor. Overall, they left the space very clean and they clearly tried their best to prevent anything from falling through. I'm mentioning this not because it's a complaint, but because I want people to have a realistic expectation of the process. Craig called me on the morning of the scheduled installation to let me know that they were running a little behind, which didn't cause any issues at all. I think they were only 30 minutes to an hour late in total, but it was communicated to me very well and it was obvious that they were trying to be as punctual as possible. I got a call from Craig a few weeks after the installation because he wanted to check in with me to see how well it was working. It's a simple gesture, but really helped make me feel like they care and take pride in their work. Again, I want to state that we have not yet had a chance to test the insulation for the primary reason we had it installed, but we have noticed a difference in heat retention and I'm very hopeful and excited to try it out in warmer weather. Based on the scheduling, installation process, and customer service: I highly recommend NP Energy and we will certainly be turning to them again if we need any more insulation."

"Alligood did a great job with the project; they were punctual, professional and thorough.  We had a couple follow up items after the initial insulation job and they came to address those as well.  Jeff and Matt were great to work with and they were very flexible on the approach to insulating our attic and basement crawl space...including some added areas above our drop ceiling in the finished basement.
For the first time since we've lived in our house (7 years), we no longer need a space heater in the basement to maintain a warm temperature during the winter (and temps have been in the teens in recent days).  Additionally, we've always had to play games with our thermostat (located on the main floor) to have the upstairs bedrooms be the right temperature at night.  Since the insulation, our house is balanced with temperature across the floors for the first time!

"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

Insulation FAQs, answered by experts

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.
