Proper attic and wall insulation is the single biggest factor in keeping a DFW home comfortable in summer and winter — and most DFW homes built before 2010 are significantly under-insulated by current code. Texas Service Experts handles this work across the Dallas-Fort Worth Metroplex following NFPA 211 standards. Free inspection, written quote, no surprise fees.
What’s actually involved
Insulation work covers blowing additional cellulose or fiberglass into existing attics, installing batt insulation in walls or floors, and installing spray foam in attic decks or crawl spaces. Each material has its place; the right choice depends on the application and the existing insulation.
DFW current code requires R-38 in attics for new construction; many homes built between 1985 and 2005 have R-19 to R-25, which is significantly below modern standards and translates directly to higher heating and cooling bills year-round.
Walls in older DFW homes often have no insulation at all (pre-1980 homes) or 2×4 wall cavity batts that have settled and degraded. Wall insulation upgrades require either dense-pack blown insulation through small access holes or full removal of drywall — both options have tradeoffs we discuss honestly.
Every insulation project starts with assessment of current condition (R-value testing, photos of what’s there) and recommendation based on the home and the homeowner’s priorities. We don’t push spray foam on jobs where blown cellulose is a better fit, or vice versa.
Why this matters in DFW specifically
DFW summers run 7+ months of high cooling demand. An under-insulated attic can be 130-150°F in August, with that heat radiating down into the ceiling — making the upstairs floor uncomfortable and forcing the AC to run constantly. Bringing the attic from R-19 to R-38 typically reduces summer cooling bills 15-30% in this region. Winter heating is a smaller benefit (mild winters mean less heat loss) but the comfort improvement on cold nights is significant.
Our process
- Attic and wall assessment — We measure existing R-value, identify air-leakage points, photograph current condition, and recommend a scope based on what we find.
- Air-sealing first — Air leaks (around recessed lights, attic hatches, plumbing penetrations, electrical penetrations) sealed before adding insulation — sealing first is what makes the new insulation effective.
- Insulation install — Blown cellulose or fiberglass to specified depth; batt insulation in accessible cavities; spray foam where appropriate.
- Final inspection and documentation — Photos of completed work, R-value documentation, energy efficiency tax-credit paperwork if applicable.
Materials and standards
We install three insulation materials based on application: blown cellulose (best for attic top-up, dense and settles less than fiberglass), blown fiberglass (lighter, faster install for new construction), and closed-cell spray foam (highest R-per-inch for unvented attics and rim joists). We don’t install open-cell spray foam for attics in this climate due to moisture issues.

| Full attic insulation (down-and-replace) | $2,800 – $5,500 |
| Wall dense-pack insulation (per wall area) | $2.50 – $4.50 per sq ft |
| Crawl-space insulation | $1,500 – $4,500 |
| Spray foam attic deck (high-performance) | $3.50 – $6.50 per sq ft |
Frequently asked questions
How much will I save on energy bills?
Bringing an attic from R-19 to R-38: typically 15-30% summer cooling savings in DFW. Wall insulation upgrade: 5-15% additional savings depending on wall area. Specific savings depend on home size, AC efficiency, and usage patterns.
Are there tax credits for insulation?
Yes — federal energy efficiency tax credits cover a percentage of qualifying insulation work. We provide the documentation needed to claim the credit. Always confirm eligibility with your tax preparer.
How long does insulation work take?
Attic top-up: typically a single 4-6 hour visit. Full attic with air sealing: 1-2 days. Wall dense-pack: 1-3 days depending on size. Spray foam: 1-2 days plus cure time.
Will it help with summer comfort upstairs?
Often dramatically — most DFW second-floor comfort issues come from inadequate attic insulation. R-38 attic with proper air sealing typically resolves most upstairs heat issues.
Will it help with allergies?
Air-sealing as part of the work reduces unfiltered outside air entering the home. For allergy-sensitive households, the air-sealing component matters more than the insulation itself.
