Why Woolsey Insulation Dallas Is Preston Hollow’s Preferred Attic Insulation Company
Preston Hollow homeowners tend to ask harder questions than most, and honestly, they should. The housing stock here is expensive to heat and cool, and a cheap insulation job on a vaulted ceiling becomes a very visible problem the first summer week the attic hits 140°F. Our crews work Preston Hollow every week. We know the 1950s ranch houses off Preston Road, the 1990s contemporaries along Strait Lane, and the newer builds near Royal Lane that still shipped with builder-grade attic insulation.
Glenn Hartley runs our operation. He’s the person who makes sure the written price you get is the price you pay, and that the crew who shows up is the crew you were told to expect. We’re independently owned and operated under the Kingswell banner, not a franchise. That means the 365-Day Done Right Promise isn’t corporate fine print. If something’s not right within 365 days, we come back and fix it at no charge. In writing.
When you call (469) 916-4622, a live person answers. Not a voicemail tree. Day or night. If your attic insulation got soaked in a hail storm and you need someone to look before the mold sets in, you’ll speak to a real person who can schedule it.
Blown In Insulation in Preston Hollow
Blown In Insulation is loose fiberglass or cellulose that gets pneumatically blown across the attic floor to build up R-value quickly. In Preston Hollow, it’s the right call for ranch-style homes and two-story traditionals with a real attic floor, especially when existing insulation has settled to R-19 or less. Most whole-attic blown-in jobs here run $1,800 to $3,200 depending on square footage and target R-value. We primarily install Owens Corning fiberglass and GreenFiber cellulose, and we’ll tell you which fits your attic instead of just using whatever’s on the shelf.
Attic Top-Up vs. Full Removal
When old blown-in insulation is dry, clean, and just underperforming, topping it up is usually the smart move. We blow new material over the old layer to reach R-38 or R-49. If the existing insulation has been wet from hail damage or roof leaks, or if rodents have made a mess of it, full removal changes the whole job. That’s when we recommend removal first, and we’ll explain why in plain language before any price is set.
Air Sealing Before the Blow
Blown-in insulation over an unsealed attic floor is like putting on a down coat with the zipper open. We air-seal penetrations around can lights, plumbing vents, and top plates first, then blow the insulation. That’s a standard part of how we work, not an add-on we pitch afterward. The written price includes it.
Insulation Contractors in Preston Hollow
Insulation Contractors in Preston Hollow aren’t all the same, and the difference shows up fastest in homes with vaulted ceilings and sloped rooflines. The wrong contractor bids the job like a flat attic, blows loose fill, and calls it done. Six months later you’ve still got a hot master bedroom and no idea why. We bid Preston Hollow attics differently because we know what the ceiling structure actually looks like before we quote. Most attic insulation projects we handle in this neighborhood land between $2,200 and $5,800, with the higher end reserved for cathedral ceiling work with spray foam.
Knee Walls and Sloped Transitions
Preston Hollow’s complex rooflines create a lot of attic knee walls, the short vertical walls where a sloped ceiling meets the attic floor. They’re almost always under-insulated. We treat them as part of the thermal boundary and insulate them properly, rather than pretending they don’t matter.
Working With Existing Roof Structure
Older Preston Hollow homes often have unconventional framing that makes standard batt installation a poor fit. We work with the structure that’s already there, choosing material that conforms to the cavity rather than forcing a square peg into a round hole. That’s one reason we carry eight insulation brands rather than just one.
Trusted Brands We Service in Preston Hollow
We install and service insulation from eight leading manufacturers, and the material recommendation is driven by what your Preston Hollow attic actually needs. For cathedral ceilings and sloped rooflines, open-cell spray foam from Icynene or Demilec fills the cavity and air-seals in one step. For flat attic floors, we often recommend CertainTeed blown-in fiberglass or Rockwool batts, which hold their shape and resist moisture better than older materials. Because we stock these products for our Dallas-Fort Worth dispatch, a Preston Hollow job rarely waits on a supplier. We show up with what your attic needs.
Common Attic Insulation Problems We See in Preston Hollow Homes
- Slumped cathedral ceiling batts. Original 1980s and 1990s fiberglass batts lose loft over time and peel away from the roof deck, leaving air gaps that let attic heat migrate into the living space. You feel it as a hot spot on the ceiling even when the AC is running hard.
- Uninsulated knee walls. The sloped transitions and short vertical walls common to Preston Hollow’s custom rooflines are routinely left uninsulated. Hot air pours through them all summer, and in a freeze event they become condensation points.
- Moisture from hail-damaged roofs. Preston Hollow takes hail hits that crack shingles and let water into the attic. Insulation that gets wet loses R-value immediately and holds moisture long after the roof is repaired. The ceiling stain shows up months later.
- Attic temps pushing past 140°F. High solar gain on large roof surfaces drives attic temperatures high enough to degrade some insulation materials. A radiant barrier at the roof line can drop surface temperatures dramatically, which we’ve verified with thermal imaging on local jobs.

FAQs About Attic Insulation in Preston Hollow
Because insulation was added to the attic floor, not to the ceiling cavity itself. Cathedral ceilings have no attic floor, so loose fill up top does nothing for the sloped section. The cavity between the drywall and roof deck needs insulation, and if old batts are slumped or missing, hot spots return quickly. We address the ceiling plane directly with cavity-filling material like open-cell spray foam. Call (469) 916-4622 and we’ll tell you what your ceiling actually needs.
Yes. A radiant barrier stapled to the roof rafters reflects most of the radiant heat that would otherwise radiate down into the attic and the living space below. On a Strait Lane vaulted-ceiling job, our thermal camera showed a 30-degree surface temperature drop the same afternoon we installed the barrier. It works best paired with proper insulation, not as a substitute for it.
It can be topped off if the existing material is dry, clean, and free of rodent activity. We add new blown-in fiberglass or cellulose to reach R-38 or R-49. If the old insulation is wet from hail or roof leaks, or if it’s contaminated, full removal comes first. We’ll tell you which situation you have before we quote anything. The estimate is free: (469) 916-4622.
Hail cracks shingles and underlayment, letting water drip into the attic where it saturates the insulation. Wet fiberglass and cellulose lose R-value dramatically, even after the roof is repaired. Worse, the moisture stays trapped and creates conditions for mold long before you see a ceiling stain. If you’ve had a roof replaced since a hail event, have the attic insulation inspected. We do those checks regularly for Preston Hollow homeowners.
Open-cell spray foam is usually the best answer. It fills the cavity completely, air-seals as it’s installed, and doesn’t slump like fiberglass batts do over time. We’ve used Icynene and Demilec foam on enough Preston Hollow sloped ceilings to know how they perform through Dallas summers and rare freezes. The price is higher than blown-in, usually $4,500 to $6,500 for the ceiling, but you get a written quote before any work begins. Call (469) 916-4622 for an exact number.
