I can’t say enough good things about this insulation company. From start to finish, they went above and beyond to take care of me. Communication was excellent, the crew was professional and respectful, and the quality of work exceeded my expectations. They took the time to explain everything, addressed all my concerns, and made sure the job was done right. It’s rare to find a company that truly stands behind their work like this. I would absolutely recommend them to anyone looking for insulation work.

What Does Attic Insulation Cost in Phoenix, AZ?

Attic insulation pricing depends on your attic square footage, your current insulation (depth, condition, type), and the material you choose: blown in fiberglass, blown in cellulose, or spray foam.

If you know your square footage and what you want done, we can usually give you a clear estimate by phone or text. If not, a free attic inspection lets us measure your current R value, check coverage and depth, and use a thermal camera to find hot spots and air leaks so we can price it accurately and recommend the right solution for your goals. Most installs are completed in one day, and we leave the work area clean.

  • Attic square footage

  • Existing insulation type and condition

  • Target R value (R-38 or R-49)

  • Whether removal is needed

  • Whether attic air sealing is included

  • Attic access and height

What R Value Should You Have in Phoenix?

Proper attic insulation limits ceiling heat gain so your home stays more consistent and your AC runs less. In Phoenix, a common target is R-38 to R-49. We measure your current depth, calculate your R value, and show exactly what it takes to reach R-38 vs R-49.

Guidance is based on the 2024 International Energy Conservation Code (IECC) Residential Provisions, Chapter 4, Table R402.1.3

Attic Insulation FAQ

Most Phoenix homes need enough attic insulation to slow extreme heat and keep ceiling temps under control. A common target for our area is R-38 to R-49.

Many homes, even newer builds, are sitting at the minimum, and older attics often have insulation that’s settled, compacted, or deteriorated over time. We measure your current depth, estimate your existing R value, and use a thermal camera scan to spot hot areas and air leaks so we can recommend the right target for your home.

Hot rooms, uneven temperatures, and high summer electric bills are common signs. We can measure your current insulation depth and confirm problem areas with a thermal camera scan.

Removal is not always needed. Many attics just need a top off, but removal makes sense when insulation is old, settled, contaminated, or dusty. It also gives us access to air seal top plates and penetrations before installing new insulation for the best results.

Yes, in many cases a top-off is the best option. If your existing insulation is dry and in decent condition, we can add blown-in fiberglass or cellulose over it to increase coverage and depth. If it is wet, contaminated, or breaking down into dust, removal and replacement is usually the better option.

Both fiberglass and cellulose can work well in Phoenix. Cellulose is dense and can achieve a higher R value per inch, but it can settle over time. Fiberglass is stable and handles moisture well, and it pairs well with attic air sealing. We recommend what fits your attic condition, budget, and comfort goals.

Spray foam can deliver the highest performance, but it also costs more and is not the best fit for every attic. For many Phoenix homes, the best value is attic air sealing plus blown in insulation to the right depth, and we can compare both options during your inspection.

Yes, especially in Phoenix where attic heat can leak into the home through gaps and openings. Air sealing is most effective when paired with blown-in insulation, because it helps keep hot attic air out and conditioned air in. We focus on common leak points like around can lights, vents, and other openings.

Cost depends on attic square footage, your current insulation, the material you choose, and whether removal or air sealing is included. If you know your attic square footage and goal, we can usually give a quick estimate by phone or text. Otherwise, we measure depth and conditions and quote it accurately after a short inspection.

Most attic insulation installs are completed in one visit. Timing depends on attic size, access, and whether removal or air sealing is included. We will give you a clear timeline before work starts.
