Why Woolsey Insulation Dallas Is Duncanville’s Preferred Attic Insulation Company
We’re led by Glenn Hartley, and we’ve been installing attic insulation and spray foam since 2002 as part of the Kingswell family of independently owned and operated insulation companies. Our Attic Insulation team shows up in uniform, background-checked, and on time. The Kingswell Guarantee is the same on every Duncanville job: a written price before work begins, a committed arrival window, a clean site when we leave, and a written guarantee covering the work for 365 days. If something isn’t right within that year, we come back and fix it at no charge. That’s in writing, on every job.
What does that mean for a Duncanville homeowner? It means when you schedule attic insulation removal and replacement in a Greenbriar split-level, the crew arrives when we said they would. The price on the work order matches the price we quoted. And if a section of blown-in insulation settles unexpectedly, we return and make it right without a debate. We answer the phone with a real person 24 hours a day, 7 days a week, which matters when you’ve got a 95-degree attic and questions that can’t wait until morning.
Attic Insulation Removal in Duncanville
Attic Insulation Removal in Duncanville is the first step we recommend for homes built before 1990 that still carry their original fiberglass. Over 40 to 60 years, blown-in insulation settles, compresses, and stops doing its job. In a Ten Mile Creek 1970s ranch, that often means the attic floor tests at R-19 or less, while Duncanville’s summer heat pushes attic temperatures past 140°F. The ceiling below gets hot to the touch, and your air conditioner runs almost nonstop.
Removal involves vacuuming out the old material, inspecting the attic floor for gaps and air leaks, and prepping the space for new insulation. A typical attic insulation removal in Duncanville runs $1,100 to $2,800 depending on attic size and access difficulty. Steep roof pitches, low clearance, or old vermiculite (which requires special handling) push toward the higher end. We give you a firm written price before the vacuum ever switches on, so you know exactly what the job costs.
Air Sealing Before You Add Insulation
Removing old insulation creates the one chance to properly air seal. Holes around plumbing vents, wiring chases, and recessed light housings pull humid Duncanville air into the attic, where it condenses on roof sheathing and feeds mold. Sealing those penetrations before adding new insulation is the difference between a job that lasts and one that fails.
What We Remove and How We Dispose of It
We remove settled fiberglass, old cellulose, and degraded batt material, bagging it on site and hauling it away. You don’t end up with a pile of old insulation in your driveway. The attic is inspected after removal, and any moisture damage or rodent activity is flagged before new material goes in.
Blown In Insulation in Duncanville
Blown In Insulation in Duncanville is the fastest way to bring an older attic up to a level that actually handles Texas heat. Loose-fill fiberglass or cellulose is blown across the attic floor to a consistent depth, filling gaps and covering the ceiling joists entirely. For a Duncanville home, we recommend R-38 to R-49 in the attic, which is well above what 1970s builders installed originally.
A blown-in insulation job for a typical 1,800 to 2,400 square foot Duncanville house runs $1,600 to $3,600. Smaller attics with easy access land on the lower end; larger footprints or awkward attic layouts push higher. The material itself costs less than you’d think. The labor and prep work, especially if we’re removing old insulation first, drive the total. You’ll have one written quote before we start, not an estimate that shifts when the crew arrives.
Owens Corning and Johns Manville Loose-Fill
We work with eight leading insulation brands, and for Duncanville attics we often recommend Owens Corning or Johns Manville loose-fill fiberglass. It doesn’t settle the way 1970s material did, it resists moisture, and it holds its R-value over time. We also stock CertainTeed and GreenFiber options, so the material recommendation fits your home, not whatever happens to be on the truck.
Blown-In for Wall Cavities
Here’s the Duncanville-specific problem we see constantly in Greenbriar and Ten Mile Creek. The original R-11 wall batts in 1960s to 1980s brick veneer homes slump inside the wall cavities over decades. Gravity pulls them down, leaving a void at the top of every stud bay. On a hot afternoon, a thermal camera shows those voids as vertical hot streaks. Blown-in insulation, usually dense-pack cellulose, fills those empty cavities from the inside of the wall. It’s a retrofit that stops heat from pouring through the walls, not just the ceiling.
Trusted Brands We Service in Duncanville
We install and service attic insulation and spray foam insulation only, and we’re brand-flexible for a reason. A 1978 Ten Mile Creek ranch with settled attic material might need Owens Corning blown-in fiberglass. A homeowner planning to finish an attic space might benefit from Rockwool batts for fire resistance and sound control. For spray foam applications, we work with Icynene and Demilec, two-part liquids that expand on contact and seal gaps airtight. We carry local stock for Duncanville customers, which means faster turnaround when you’re ready to schedule.
Common Attic Insulation Problems We See in Duncanville Homes
- Settled 1970s blown-in attic insulation. Material installed at R-30 decades ago has compressed to R-19 or less. Ceilings feel warm in the afternoon, and upstairs rooms never quite cool off.
- Slumped R-11 wall batts. The original batts in 1960s-to-1980s brick veneer homes drop inside the wall cavities. Thermal imaging shows hot streaks at the top of exterior walls on summer afternoons.
- Missing air sealing at attic penetrations. Open gaps around can lights, bathroom fans, and plumbing stacks let humid air rise into the attic. Condensation forms on roof sheathing, and mold follows.
- Uneven insulation coverage. Original builders often skipped insulation over garage ceilings, cantilevered floors, or knee walls. These spots act like open windows in Duncanville’s heat.

FAQs About Attic Insulation in Duncanville
Look for ceilings that feel warm to the touch on a summer afternoon, upstairs rooms that won’t cool below 80°F, or energy bills that climb every July. In Ten Mile Creek and Greenbriar homes from the 1970s, settled blown-in insulation often tests at R-19 or below. The only sure way to know is a thermal scan and an attic inspection. Call (469) 916-4622 and we’ll check it at no charge.
Yes, and we usually recommend it for homes with original 1970s material. Removal lets us air-seal the attic floor before new insulation goes in, which is the part that actually stops humid air from condensing on your roof sheathing. Attic insulation removal in Duncanville typically runs $1,100 to $2,800, and you’ll see the written price before we begin.
For Duncanville’s climate, we target R-38 to R-49 in the attic. That handles the 95°F afternoons and the humidity that drives condensation problems in under-insulated attics. Many 1970s Duncanville attics test at R-19 or less, which means your ceiling is absorbing far more heat than it should. We’ll give you a specific recommendation based on your attic’s condition and your home’s construction.
Not always, but it’s worth checking. The original R-11 batts in 1960s-to-1980s brick veneer homes slump over time, leaving empty voids at the top of wall cavities. A thermal camera shows those voids as hot streaks on a summer afternoon. Dense-pack cellulose can fill the cavities without tearing out drywall. Call (469) 916-4622 for an exact quote, estimates are free.
Most removal and replacement jobs in Duncanville take one to two days. A straightforward attic with easy access finishes in a single day. Jobs with steep pitches, low clearance, or old vermiculite requiring special handling take two. We’ll give you a committed arrival window before we start, and the crew leaves the site cleaner than they found it.
