"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."

"We had St. Louis Insulation seal and insulate the crawlspace in our one-story 3-bedroom brick home in early December. The existing insulation was probably original from the mid-70s and was falling from the ceiling of the crawlspace, about half already on the floor. SLI provided an estimate and described their procedure -- sealing, not just replacing the rolls of insulation but sealing the floor and walls and vents. They described the timeline for the work. The estimate was pricey, but well in line with other providers of the same service, and it's a one-time job, not an every-20-years job. Ultimately we selected SLI as we were impressed by reviews of their work and by their professionalism and the clarity of their description of the work to be done. They arrived punctually and performed the work very fast, considering the nature of the work (removing all old insulation and all the other debris down there, putting in the new plastic and insulation and foam spray). I was very impressed by their politeness, efficiency, and the cooperation they showed in working together. (They're in the crawlspace and so if they had yelled or even been grumpy with each other, I'd have heard it.) They removed approximately 24 very large stuffed trashbags of old insulation (it's a large crawlspace) and stacked them neatly on the driveway, then put everything in their truck and hauled it away. (That was the first day.) They brought in the supplies of the new work -- holy cow, lots of plastic, tanks for the foam spray etc -- and quickly installed all of it. (That was another half-day.) They supplied photos of the work so that I didn't need to get into the crawlspace to see what they'd done. The work was fully completed within the time they had estimated. And everything they did was cleaned up. I would recommend, without reservation, their work. Great people, very professional, and they clearly have done this enough that they are very well organized. Because the entrance to our crawlspace is in the floor of a bedroom closet, they kept that bedroom closed while they were working, and took everything in and out via a window. It kept any mess localized, so that I did have to do a thorough cleaning of the carpet and all surfaces in the room but it was only one room, and I was cleaning the dust basically -- all their supplies and any trash were totally removed. So A+ on that. One small unforeseen issue was that we have small dogs, and we had not thought about the spray foam and any fumes, and SLI did not think of that either, until the day they were going to do the spray foam. We had to quickly move the dogs to another part of the house, and near a window, where they would be less exposed. (They're pugs so I think the fumes would not be an issue for a larger dog -- we just need to be careful because they're pugs.) If you have small dogs, or pet birds, you will want to consider how to keep them safe during the foam spray. Overall, St. Louis Insulation did a great job. They said exactly what they'd do, and they did it. Considering the nature of the work required (bending or kneeling in a crawlspace, hauling huge bags of old insulation and rolls of plastic while bending or kneeling), I am hugely impressed with the professionalism and with their good-natured attitude. They are very good at what they do."

"I’m a land lord of 72 residential properties and the biggest head ache other than common upkeep was the constant battle with roaches and insects inside the units, I had Triple B come out and put their pest control infused insulation at 10 of my properties and within 3 weeks the tenants were in shock at how affective it was, they went from seeing them everyday to hardly ever, I ended up getting them to do all my units and also my own house, this will be a must at any property I ever purchase, highly suggested for new home owners/buyers"

"First : I was concerned with the negative reviews .So i contacted them and asked for an explanation ..I was satisfied with what they had to say ..and I thought their honesty was refreshing 
My electric bills were 2 times more than my neighbors 
2) i scheduled a home assessment .. and even though we had a schedule change communictaion was always good 
3) after assessment they suggested $5000 plus in upgrades , but gave no pressure to use their service ..I researched the cost of DYI vs. using them and consulted with Ameren to advise ..I decided Peterson was about 25% more than doing the job myself and was satisfied that was worth not doing the job myself 
4) but I saved a little by doing the easiest job myself ...Insulating  my open basement rim joists 
5) The workers were quick /clean/courteous/and professional ...THEY CLEANED AFTER THEMSELVES !!!
6) Work was complete and I am 100% satisfied 
I have waited a few months to see if my energy costs went down (before reviewing) ... It is hard to accurately quantify savings ...but in comparison to neighbors it seems to have a 35-40% reduction in electric use during warmer months ...That said I would still have a few years to break even with  cost of insulation ...BUT the comfort level in our house was well worth the costs ..We used to have a warm upstairs and used a a/c window unit to keep up ..We no longer need window a/c and everyone is happier and house temps are more moderate on each level 
Final assessment : It was expensive but well worth it and Peterson was a very good provider of advise and services

Insulation questions, answered by experts

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

Minimal, mainly occasional checks for damage or mold in extreme conditions.

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.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.
