Frequently asked questions
Helpful answers before we begin.
Every property is different, but these answers cover the questions we hear most often.
How much insulation does my attic need?
A typical code-level attic target is R-38. With the blown-in product we install, R-38 is approximately 13 inches. We can add more insulation for a higher R-value if desired.
Do you remove old insulation?
Yes. We remove old or damaged insulation and prepare the area before replacement when removal is included in the project scope.
Do you install crawlspace vapor barriers?
Yes. We install crawlspace insulation and both 6-mil and 20-mil vapor barriers.
How long does installation take?
Most installations are typically completed in one day. Larger projects, removals or more involved work may require additional time.
Do you provide free estimates?
Yes. NRJ Insulation provides free estimates. Call, text or submit the website form with your address, project details and photos if available.
Energy savings
Your insulation project may qualify for incentives.
Upgrading attic insulation and sealing air leaks can improve comfort and reduce wasted energy. Some Duke Energy customers may qualify for home-efficiency rebates based on the home, existing insulation level and current program requirements.
