"Prompt responses and focused quote visit and interaction regarding insulation R-60 goal for two attic areas and any additional suggestions. Provided a quote that was within Angi’s price range for install labor per sqft and insulation cost per sqft. Arranged install date, arrived as expected, installed drop cloths in areas affected, installed insulation, shared installed video of both areas, and thoroughly cleaned up interior work areas satisfactorily. Very happy and impressed with Reynier personally and his work effort. Will consider him for other work I might need in the future."

"They were wonderful and extremely professional. They identified some issues that were due to improper installation when the home was built. They had to change out all of the old venting and it looks like it's in brand new condition. They made sure all of the colors matched perfectly. They completed the job by blowing in the proper amount of insulation. We have already seen a huge difference in our air conditioner's performance. It used to run non-stop on 80 degree days, but now it cycles throughout the day the way it should. We are so pleased with Dan's team that we requested a quote for a new roof and insulation for our lake house. We highly recommend Dan and his team."

Insulation FAQs, answered by experts

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

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.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.
