"As a retired contractor I can say that these guys do it right. Estimator/salesman (Jay) arrived right on time for his appointment and sent an estimate by email within about twelve hours. Calls were returned, questions answered and proposal was clear and to the point. Appointment was scheduled with no difficulty and the crew - two very tidy men - arrived a few minutes early for the installation. (Jake and a name I did not catch) The job consisted of spraying a confined attic area which contains an air handler and the box beam around the cellar foundation. This was all done cleanly and within a few of hours. Drop clothes were placed every where necessary and the floors were covered more than adequately.  When they left, other than the work they had done, I would not have known they had been here. 

   This was a retrofit to stop heat leakage from the attic area which contains the air handler and which was causing enormous icicles over the front entrance and cold infiltration from the cellar. This was something of an experiment to see what difference the insulation will make this winter. They have other insulation services and I will be calling them to price a couple of other projects as time and cash flow allow.  Keep in mind, spray foam is lumpy. It does not present a flat  surface when finished and no one should expect it to disappear into the background unless it is behind sheetrock. That is another kind of installation.

Insulation FAQs, 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.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

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

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.

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.
