"AA arrived when promised, their price was much better than the other two bids, and the house is much cooler than before. After a hurricane knocked down two big trees that shaded my house we needed to upgrade the insulation. AA is experienced, completed the job on time, and made us much more comfortable."

Insulation FAQs, answered by experts

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

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.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed
