Thistledown Insulation San Antonio is an independently owned Cedarwell-family company, founded in 2003, and we’re held to the Cedarwell Care Promise on every visit. That means our background-checked, uniformed technicians lay drop cloths across your hallway and wear shoe covers from the front door to the attic hatch, no exceptions. We’re the crew that cleans up like it’s our own home, asks before we move or touch anything, and photographs the clean-up before the van pulls away. Timberwood Park homeowners keep calling us back because the written price we give before any work starts is the exact number on the invoice when the job is done. And if anything isn’t right, the 365-Day Done Right Promise means we make it right, no debate, no fine print.

Our crews are local to the Timberwood Park area and respond to homes between Borgfeld Road, Blanco Road, and the neighborhoods down toward Camp Bullis. We know what waits in these attics. Squirrels from the oak canopy, settling blown-in fiberglass from the 1990s, vaulted ceiling chases that were never sealed properly. When you call, a live person answers 24/7, and we schedule around quiet hours if the baby is napping. See our full Attic Insulation service area and how we work across the metro.
Radiant Barrier in Timberwood Park
A radiant barrier in Timberwood Park is a reflective layer installed on the underside of your roof deck, designed to reflect radiant heat before it soaks into your attic insulation. Why does this matter here specifically? Timberwood Park’s large custom homes sit on heavily wooded lots, and those big oaks actually work against you in summer. Trees block the breeze but trap heat close to the roof deck, and an under-insulated attic in these conditions can hit 140°F by early afternoon. A radiant barrier drops that temperature by 20 – 30 degrees, which takes real strain off your AC system. In Timberwood Park, radiant barrier installation typically runs $1,400 – $3,000 depending on attic size and roofline complexity. You’ll have your exact written number before we touch a rafter.
Cedarwell Care Promise on Radiant Barrier Jobs
When our crew installs radiant barrier on a Timberwood Park home, the process is quiet and controlled. We use quiet tools when children are sleeping. We ask before we move anything stored in your attic. And we leave a photo of the clean-up before the ladder comes down. That’s the Care Promise, and it applies to every single job, not just the big ones.
Radiant Barrier vs. Recessed Light Leaks
Here’s something we see in Timberwood Park that you won’t find much in newer tract-home suburbs like Stone Oak: recessed can lights buried under blown-in insulation, leaking conditioned air into the attic. A radiant barrier helps with radiant heat, but if those can lights aren’t air-sealed with rated covers first, you’re still losing cool air through the fixtures. We check for this on every radiant barrier install, because in these custom homes the leaks hide everywhere.
Attic Cleaning Services in Timberwood Park
Attic Cleaning Services in Timberwood Park involve removing contaminated or pest-damaged insulation, vacuuming debris, sanitizing the space, and preparing the attic for new insulation or a radiant barrier. The wooded lots in Timberwood Park mean squirrels and rats find their way in through soffit gaps and gable vents all the time. Once they’re in, they nest in fiberglass batts, leave droppings, and shred insulation down to bare drywall. That’s not a small nuisance. That’s a moisture and air quality problem in the space directly above your children’s bedrooms. Attic cleaning in Timberwood Park typically runs $1,200 – $2,800 depending on attic size and the extent of contamination. You’ll get a written price before any work begins, every single time.
Restoring Attics After Pest Activity
We vacuum contaminated fiberglass, sanitize the attic deck, and remove the nesting material that’s been sitting up there for who knows how long. On a custom home near Timberwood Park’s namesake park, our crew pulled back settled fiberglass batt around a vaulted ceiling chase and found rodent-disturbed insulation from squirrels nesting in the attic. We air-sealed the recessed can lights with rated covers, vacuumed the contaminated fiberglass, and blew in GreenFiber cellulose to R-49, eliminating the hot spot the homeowner had felt above the master bedroom. That’s the kind of thing no bid site tells you about, but our crews deal with it routinely out here.
When Cleaning Precedes New Insulation
You don’t always need to remove old blown-in fiberglass before adding insulation. But you do when it’s been saturated by a roof leak, shredded by pests, or compacted to the point it isn’t doing anything. Timberwood Park’s humidity makes damp insulation a mold risk, so we test the condition before recommending a full removal or a top-up. We never push a removal that isn’t necessary.

Pet-safe product options are available where a choice exists, so the dog can be home during the job.
Common Attic Insulation Problems We See in Timberwood Park Homes
- Recessed can lights leaking air and trapping moisture. Timberwood Park’s custom homes are full of recessed lighting, and most of those fixtures are not air-sealed. They leak conditioned air into the attic while trapping moisture under the blown-in insulation, which is exactly the condition local energy auditors flag most often.
- Pest-disturbed fiberglass batts. Squirrels and rats from the oak canopy nest in attic insulation, leaving bare spots that spike summer AC loads and contaminate the insulation with droppings. This is a year-round problem on wooded lots, not just a winter issue.
- Vaulted ceiling chases acting as hidden air channels. Humid attic air moves through unsealed chases and condenses on the back of drywall, staining ceilings and feeding mold. Homeowners rarely see the source until we pull back the insulation.
- Settled or compacted blown-in insulation from the 1980s and 1990s. Many Timberwood Park homes were insulated well when built, but fiberglass settles over 30+ years, dropping from R-38 to R-19 or lower in spots. The high ceilings and big attics hide the problem until the energy bill shows it.

FAQs About Attic Insulation in Timberwood Park
Mold in Timberwood Park attics is almost always a moisture problem, not an insulation-quantity problem. The area’s high humidity means warm, moist air moves through recessed can lights, vaulted ceiling chases, and unsealed penetrations, then condenses on cooler drywall and framing. Fiberglass batt doesn’t stop air movement, and that airflow carries the moisture. We air-seal the penetrations, ensure baffles are moving air properly, and then install or top-up insulation. Call (903) 437-9164 and we’ll inspect your attic and explain exactly what’s causing the mold before you spend a dollar on fixes.
No, you don’t need to remove old blown-in insulation before adding a radiant barrier. A radiant barrier installs on the roof deck or the underside of the rafters, not on top of the insulation. What you might need to address first is whether that old blown-in insulation has been contaminated by pests or moisture. If it’s dry, settled but still functional, and free of rodent activity, it can stay. Call (903) 437-9164, and we’ll assess it for free.
Timberwood Park’s occasional freezing nights mean your attic insulation has to handle cold snaps without trapping moisture. Blown-in cellulose like GreenFiber performs well here because it fills the irregular cavities in custom rooflines and resists settling. Air sealing matters just as much as the insulation itself, because warm, humid air from the house moving into a cold attic is what causes condensation. We account for both heat gain in summer and moisture control through winter while still handling those rare freeze events.
Yes, squirrels absolutely damage attic insulation in Timberwood Park, and they don’t need much of a gap to get in. They enter through soffit gaps, damaged gable vents, and roof intersections, then shred fiberglass batts for nesting material and leave droppings throughout the attic. The result is bare spots that let heat pour in and contaminated insulation that should be removed and replaced. Attic cleaning and insulation replacement after pest activity is one of the most common jobs we do in Timberwood Park.
Recessed can lights cause hot spots because they leak conditioned air from your living space into the attic, and they trap moisture under the insulation that sits on top of them. In Timberwood Park’s custom homes, these fixtures are everywhere, and most were installed without air-sealed covers. We install rated covers over the cans, air-seal the gap, and then insulate around them properly. The hot spot above the master bedroom disappears, and the ceiling stays dry.
