Insulation Company in Dallas, TX
Dallas homes fight a specific battle every summer: a 96°F July sun beating down on low-pitch roofs while the attic underneath turns into an oven. We’re Woolsey Insulation Dallas, and we focus on two things only – attic insulation and spray foam insulation – because those two jobs deliver the biggest comfort and energy return for the housing stock here. Our crews work throughout Dallas, from the 1950s brick ranches in Lake Highlands to newer builds in Preston Hollow, and every job starts with a written price before any work begins.

Why Dallas Homes Are Different
Dallas has a huge stock of single-story ranch homes built between the 1950s and 1980s, most on slab foundations with brick veneer, low-pitch roofs, and vented attics. That slab-on-grade construction means you can’t insulate underneath the floor the way you would with a pier-and-beam house. The attic becomes the only real thermal boundary between your living space and the roof, which is why getting the attic right matters so much here. Many of these homes still have their original fiberglass batt insulation, now compressed by decades of storage boxes and foot traffic, with gaps around recessed lights and uneven coverage across the deck.
The climate pushes things further. Dallas runs a humid subtropical pattern: long, very hot summers with intense solar radiation, mild but variable winters, and the occasional ice storm. Keeping heat out of the attic in summer is the primary insulation concern, not keeping heat in. Humidity adds moisture challenges, and freeze-thaw cycles in winter can test any installation. In neighborhoods like Lake Highlands and Preston Hollow, we regularly find 1960s-era R-19 attic insulation that was barely adequate when new and has settled well below that. Adding a radiant barrier to the underside of the roof deck can cut attic temperatures by 30°F – a difference you can feel immediately when you climb up there in August. On the code side, Dallas has required R-38 attic insulation since a 2015 update to the local energy code, which drives a lot of retrofit work in older neighborhoods where the original install never came close.
Our Main Dallas Services
Dallas homeowners call us about two insulation jobs more than anything else. Here’s what each one involves here.
Attic Insulation in Dallas
Most Dallas attics we see need either a full replacement of settled fiberglass batts or a blown-in upgrade to meet the R-38 code requirement. Blown-in insulation – loose fiberglass or cellulose blown through a hose to fill every cavity – works especially well in Dallas attics because it settles into the uneven spaces common in 1960s and 1970s framing. We check for gaps around recessed lights, bathroom fan housings, and attic hatches before recommending a material. For the full picture on materials, pricing, and what the job looks like, see our dedicated page: Attic Insulation in Dallas.
Spray Foam Insulation in Dallas
Spray foam insulation – a two-part liquid that expands on contact and seals gaps airtight – is the right call for Dallas homes with ductwork running through the attic, which is common in slab-on-grade construction. Open-cell foam handles the heat and humidity well, while closed-cell adds structural rigidity and a strong air barrier. In vented attics, foam often pairs with a radiant barrier to handle the solar load. We install both open-cell and closed-cell systems from brands like Icynene and Demilec. Details are on the service page: Spray Foam Insulation in Dallas.

What pushes price up in Dallas is the access work: low-pitch roofs on 1950s ranches often mean tight attic access and limited headroom, and existing insulation that has to be removed first adds time. What doesn’t change is the price once we give it to you – every Woolsey job gets a written price before any work starts, with no door-step surprises. That’s The Kingswell Way: say the price, show up in the window, leave it cleaner than you found it, put the guarantee in writing, come back if it fails.

What Dallas Customers Say
"Insulation job was done well. Scheduling took a little longer than I'd have liked, they were booked out a couple weeks. But once they came it was quick and the house is cozier."
- Felicia Grant"Showed up on time, laid down protection on the floors, and were careful going into the attic. Explained exactly what they were doing and why. House holds its heat so much better now."
- Preston Hale"Drafty old house that never felt comfortable. After the attic and some air sealing it's a different place. On time, clean, and the quote didn't change. Wish I'd done it years ago."
- Dmitri Kozlov
