"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 questions, answered by experts

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.
