How much does attic insulation cost in DFW?

Most DFW homeowners pay $1,500–$4,500 for a full attic insulation upgrade. Blown-in fiberglass runs $800–$2,500, spray foam $2,500–$6,500, and radiant barrier add-ons $500–$1,200. Cost depends on attic square footage, current R-value, and insulation type. Get a free estimate to see exact pricing for your home.

What R-value do I need in Texas?

The U.S. Department of Energy recommends R-38 to R-60 for Texas attics. Most DFW homes built before 2005 have R-19 or less — well below this standard. For most DFW homes, targeting R-49 is the sweet spot between cost and performance.

How long does attic insulation installation take in DFW?

Most DFW attic insulation jobs complete in one day. A standard 2,000 sq ft attic blown-in job typically takes 3–5 hours. Larger homes or jobs requiring insulation removal first may take two days. Your matched contractor will give you a specific timeline during the free estimate.

Blown-in vs spray foam — which is better for DFW homes?

Blown-in insulation is the right choice for most existing DFW homes — it's cost-effective, fast to install, and delivers excellent R-value. Spray foam is the premium option for new construction or homes with significant air leakage issues. For most Plano, McKinney, and Garland homeowners, blown-in plus a radiant barrier delivers the best return on investment.

Can I add insulation on top of existing insulation in Texas?

Yes — in most cases you can add blown-in insulation directly on top of existing insulation to bring it up to R-38 to R-60. This "top-up" is the most cost-effective approach for homes with some existing insulation. If the existing insulation is damaged, moisture-compromised, or contains mold, removal and replacement is recommended first.

Why DFW Attics Are the #1 Energy Problem

Attic insulation acts as a thermal barrier between your living space and the extreme heat above. In DFW, where attic temperatures regularly reach 130–150°F in summer, inadequate insulation forces your AC to work constantly — driving up energy bills and shortening equipment life. The DOE recommends R-38 to R-60 for Texas attics, but the majority of DFW homes built before 2005 have R-19 or less.

Heat Rises Into Your Home

Without adequate insulation, 130–150°F attic air radiates heat directly into your living space, making upstairs rooms unbearable and forcing your AC to run non-stop.

Up to 40% of Cooling Energy Lost

DOE and ENERGY STAR data shows up to 40% of cooling energy escapes through a poorly insulated attic — the single biggest source of energy waste in most DFW homes.

15–25% Cooling Cost Reduction

Properly insulated DFW homes see 15–25% reductions in cooling costs, with most upgrades paying for themselves in 3–5 years.

Year Round Benefits for DFW Homes

Most DFW homeowners think of insulation as a summer upgrade. But the same insulation that blocks summer heat also retains warmth during North Texas winters. DFW averages 36 freeze days per year with January lows averaging 33°F. Arctic outbreaks called blue northers can drop temperatures 50°F in hours. A properly insulated attic keeps heat in when temperatures plummet.
