Attic Insulation in Phoenix, AZ

Most homes in Phoenix need enough attic insulation depth to block extreme heat and keep ceiling temperatures down. The Department of Energy guidance for the Phoenix area is typically R-38 to R-60, which is roughly 13.25 inches (R-38) up to about 20 inches (R-60) depending on the material and how it’s installed. Many homes, even newer builds, have only the minimum installed and older homes often have insulation that has settled or broken down over time. During our inspection we measure your current insulation depth and use a thermal camera scan to recommend the right target for your home.

Many Phoenix homes, especially older builds, are under-insulated or have insulation that has settled and broken down over time. Even newer homes often have only the minimum required. We measure your current insulation depth and use a thermal camera scan to find hot spots, then recommend a custom attic insulation solution. High energy bills and hot rooms are common signs.

Only when it makes sense. Many attics just need a top-off, but removal is recommended when insulation is old, damaged, contaminated, or dusty. It also allows targeted air sealing around can lights and vents to stop hot attic air from leaking into your home. We’ll review the best option during your inspection.

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’s contaminated, damaged, or broken down into dust, removal may be the better option.

Both fiberglass and cellulose can be great in Phoenix. Cellulose is dense and seals around fixtures well with higher R-value per inch, but it can hold moisture and settle over time. High-quality fiberglass resists moisture and stays stable, but needs more depth to hit the same R-value, and it pairs well with air sealing. We recommend what fits your attic, budget, and comfort goals.

Spray foam can be better than blown-in insulation for attics when the goal is to stop air leaks, reduce dust intrusion, and improve comfort especially if your HVAC ducts or equipment are in the attic and you want a more temperature-stable space. However, it isn’t always the best choice: spray foam costs more, performance depends heavily on proper installation, and it can complicate future roof repairs or moisture management. For many Phoenix homes, the best value is often professional attic air sealing plus blown-in insulation to the right depth, while spray foam makes the most sense when you need maximum air sealing or an unvented attic design.

Yes, especially in Phoenix where attic heat can leak into the home through gaps and openings. Air sealing is most effective when paired with attic 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, how much insulation you need, material choice (fiberglass vs cellulose vs spray foam), access, and whether removal or air sealing is included. If you already know your attic square footage and what services you need, we can often give you a quote instantly over the phone. Otherwise, we’ll inspect the attic, measure existing depth, and scope the work so you get a clear recommendation and accurate price.

We can often book attic inspections as soon as tomorrow. The easiest way is to schedule instantly on our website by choosing the exact date and time that works for you, no emails or back-and-forth needed. For attic insulation installation or removal, we can typically get most projects on the calendar the same week once we confirm the scope

Most attic insulation installs can be completed in one visit. The exact time depends on attic size, access, whether removal is needed, and how much air sealing is included. After the inspection, we’ll give you a clear timeline before any work starts.

Yes, in many Phoenix homes hot rooms are caused by uneven attic insulation, settled insulation, or air leaks that let attic heat into the living space. Adding insulation to the right depth and fixing key leaks often makes a noticeable difference. During your inspection, we use a thermal camera scan to pinpoint the areas that are underperforming.

Blown-in insulation stays in the attic, and we take steps to keep the home clean. We protect the access area, control the work zone, and clean up before we leave. You get the benefit of added attic insulation without a mess in the living space.
