"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."

"St. Louis Insulation did a great job with insulating and ventilating both the attic and basement of our 123-year-old house in STL city. Zac was very knowledgeable and helpful and the service was affordable. The job was done quickly and efficiently. I highly recommend them for any insulation needs in the city."

"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

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency.
