"G.E.G. did a great job installing blow in insulaltion in my attic. They were quick and prepared. My only wish is they would have been able to pull up more of the unused attic flooring and gotten more insulation under it, though they were able to increase insulation in other areas."

Customers say: Quick response

"I highly recommend this business. I recently moved to the Lancaster area after purchasing a house that was built in the early 50s which needs some overdue maintenance. The attic insulation was old, worn out, and installed incorrectly. King Conservation gave me an estimate I was happy with and I agreed to having them do the work. They came in and air sealed the attic, removed the old insulation that was not needed, then installed new insulation properly. The team that came in were very professional and did a great work. I am very happy with the difference it made with the warmth in my house. I will definitely have them back to work on my basement insulation. 5 Stars!! Thank you Casey and the rest of the crew."

Insulation questions, answered by experts

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

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.

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.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.
