"I got several estimates from several providers. The pricing seemed just ok with those other providers but something seemed off. Good Life came in and made sure that I was getting the correct amount of insulation (where the other service providers had under estimated) and helped me to get into a loan through the utility company for the cost of the insulation. Good life is a qualifying contractor for this and it saved me a lot of out of pocket expense. They came in and did what they had to do. They were professional and made sure the work was done well."

"Great Customer Service equals great company. This is the first review I have ever written, but I was so impressed with Good Life Energy Savers that I had no option. Based on other internet reviews I hired Good Life Energy Savers to insulate my attic and exterior walls. Based on only a two-year sample I saved about 20% on my oil costs, but that is not why I am writing this review. This past Friday I called Good Life Energy Savers about an issue I found. I was told they would get back to me on Monday, and they did. They asked if they could come by to see the issues the same day, which they did. They acknowledged the issue and simply said they will take care of it, and they did. On Thursday morning a crew came by to fix it. They did an excellent job and went above and beyond to satisfy me (the customer). Having been in the business world for over 40 years, I know not every job goes perfectly, so good customer service is important. This was excellent customer service. I could not believe the effort they put in to make the job perfect. Thank you, Mike and the team Sincerely, Mark O"

"Stu and his team did an excellent job. They were very professional and quickly, efficiently and cleanly put new blown insulation on the attic floor of my old house. He also explained clearly how the insulation works, the R values and benefits. Thank you Discount Insulation."

"Anthony and his team did an incredible job insulating our full gut remodel in Fairfield. He took the time to put together a foam package that made the most of our budget. The crew was polite, neat and efficient. They took great care to cover finished surfaces before spraying and did a thorough clean up so we could jump right into sheet-rocking. Highly recommended for quality of work, constant communication and value!"

"Their customer relations are outstanding and their work is meticulous. It's to soon to see what my energy savings will be, but they sprayed my attic to a very substantial thickness. You might find someone a bit cheaper, but you are going to get what you paid for and Energy Evolution is worth every dollar that you pay them."

"Fausto and his team were great! I would have no hesitation in using them again. I had the attic space of a two-family building insulated with blown-in cellulose. I had already used Tigasi Home Improvement for a smaller Rockwool basement ceiling job and they were very reasonable in price, thorough and clean so I turned to them for this project. Again they gave me what I thought was a reasonable quote for removing old insulation, sealing gaps and then insulation, and Fausto explained the process well. He was very patient and understanding with my tenants' concerns, as access was via a drop down ladder in one unit's hallway. I also wanted an extended platform for storage in the attic and they were able to sort this out for a reasonable price.The team kept the job site extremely tidy and they were pleasant throughout. I would not hesitate to use Tigasi gain for another project. Plus I found them to be just really, really nice guys! A before pic and some after here."

Insulation questions, answered by experts

Yes, guiding choices between open-cell and closed-cell foams based on needs.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

Insulating windows with plastic works, but it can be time-consuming, and the end results can—and often do—end up lacking in aesthetics. Window film and caulking your windows to make sure there are no drafts are two options that increase the energy efficiency of your home in a low-cost way. Plastic can be a good strategy while you consider alternatives.

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

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.
