"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

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

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.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.
