"What an absolute DREAM! Correct Energy is an incredible company. Knowledge, professional and efficient! I contacted a few insulation companies but the proposed methods were not through. Correct Energy and especially Ray’s knowledge and experience were above and beyond. CE came out to assess and spent a generous amt of time explaining EVERYTHING. CE came when they said they would. The crew was professional and spent a few days here. They left everything immaculate. My place is old, built in the 1940’s so many challenges came up that they handled like absolute pro’s. Their work has and will continue to save so much on energy, the difference of before and after is immediate and drastic. I can’t wait for them to come back and do my basement next! I can't say enough about this company. Pros work here!!! Hire them!!! You will not be disappointed.."

"I'm a General Contractor (Jon Beer Contracting is my company) and recently worked with Corey and his team from Prestige Energy Solutions. We are doing a combination of a gut renovation and a new build on my own personal home that had a lot of tricky details and moving parts. From start to finish his team was professional, attentive, clean and skilled. I wouldn't hesitate to hire him for our future insulation needs."

"I was lucky to come across this company on home advisor, Michael, Devon, and Shane exceeded my expectations. They were quick and professional. These guys treated mold and replaced the insulation in my new home, and went as far as removing all of the junk left by the previous owners. My crawl space looks like a completely different home within the week it took them to complete the job. I couldn't have asked for a better job, and I intend to mention them whenever I hear someone in need of work!"

"Dan and Josh were incredible. Not only were they both friendly and extremely knowledgeable, but the were early on the day the work was to be done. They explained exactly what they were doing. They showed me progress along the way. They had recommendations and were adaptable to my schedule. The results were shocking. We live in an old lake house and really needed to improve the insulation. There were spots where there was little to no insulation and some where there was insulation but not enough. Even the first night the difference was amazing. I can't recommend Dan and Josh enough. So worth the money I spent. You need insulation hire them. I promise you will be thrilled."

Insulation questions, answered by experts

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

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.

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
