Insulation Company in Oak Cliff, TX
Woolsey Attic Insulation is the insulation company Oak Cliff homeowners call when an old house finally pushes back against another Texas summer. Most homes here were built between the 1920s and 1960s, and many still have no attic insulation at all, or a thin layer that settled decades ago. The result is predictable: upstairs rooms that feel ten degrees hotter than the rest of the house, heating bills that spike every January, and moisture problems that never quite go away. We focus on two things only – attic insulation and spray foam insulation – and we do them with a written price before any work starts. Call (469) 916-4622 and a real person answers, any hour, any day.
Why Oak Cliff Homes Are Different
Oak Cliff’s housing stock is older than almost anything else in Dallas. Craftsman bungalows, minimal traditional cottages, and ranch homes from the 1920s through the 1960s dominate neighborhoods like Wynnewood, Kiest Park, and Elmwood. Many of these houses sit on pier-and-beam foundations, and plenty still carry original knob-and-tube wiring in the walls and attic. That matters for insulation work because you cannot simply blow insulation over certain older wiring configurations without creating a fire hazard. It takes someone who knows what they’re looking at.
The climate adds another layer. Oak Cliff summers regularly push past 100°F with humidity that makes attics feel like ovens. Winters bring freezes and the occasional ice storm. Homes here were built before modern insulation standards, so radiant heat gain through the roof and air leakage around old framing are the real problems. We routinely find attics where insulation has flattened to R-4 or less, far below the R-38 minimum recommended for North Texas. When Glenn Hartley and his crew open an Oak Cliff attic, they expect decades of heat, dust, and critter activity, and they plan the job around it.
Our Main Oak Cliff Services
Oak Cliff homeowners reach out to us for two jobs more than anything else: upgrading tired attic insulation and sealing homes with spray foam. Each service has its own page with full details.
Attic Insulation in Oak Cliff
Older Oak Cliff homes often have shallow or nearly nonexistent vented attics, so attic insulation work here usually involves adding baffles to keep airflow moving, sealing rim joists, and sometimes insulating floors over crawlspaces. We remove old, settled material when needed, then install fresh insulation at the right R-value for this climate, and we give you a written price before we touch anything. Learn more on our Attic Insulation in Oak Cliff page.
Spray Foam Insulation in Oak Cliff
Spray foam – a two-part liquid that expands on contact and seals gaps airtight – works particularly well in Oak Cliff’s older wall cavities. In neighborhoods like Wynnewood, original exterior walls often lack sheathing under the brick veneer, with only tar paper between studs and brick. Blow-in cellulose or foam injection must be done carefully there to avoid trapping moisture. We use open-cell and closed-cell foams from brands like Icynene and Demilec, chosen for the specific wall assembly, not whatever is on the truck. See the Spray Foam Insulation in Oak Cliff page for full details.

What Oak Cliff 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."
