San Antonio heat doesn’t mess around. Attics here routinely hit 140°F in July and August. That radiant heat pushes straight through your ceiling into living space if your insulation has settled or was never enough. We’ve spent years fixing exactly that problem in homes built during the 1990s boom, in century-old bungalows near Monte Vista, and in newer far-west construction where builders skipped air sealing. The local housing stock has real, predictable failure points. We know where to look.
Key Takeaways:
- Written price delivered before any work starts, every time.
- Live arrival tracking plus before-and-after photo proof on every job.
- 365-Day Done Right Promise covers workmanship in writing for a full year.
- Blown-in, batt, removal, top-ups, and baffle work across San Antonio.
Why Laurel Attic Insulation San Antonio Is San Antonio’s Preferred Attic Insulation Company
We built our reputation on showing up when we say we will and putting prices in writing. That matters more in San Antonio than most places, because the summer heat turns a two-week insulation delay into a two-week stretch of brutal cooling bills. Homeowners around Stone Oak, Jefferson, and Beacon Hill call us because our technicians arrive at a live, trackable time, not a vague four-hour window. Background-checked and uniformed. The Relay Visibility Guarantee is standard on every job: you see where your tech is, you get photo updates, and you pay from a digital invoice link.
Chase Whitaker runs the team with a simple rule: if the insulation isn’t right, we make it right. That’s the 365-Day Done Right Promise, in writing. No argument, no second invoice. We also offer a free second visit if any repair fails during that year. People in San Antonio have plenty of contractor horror stories. We exist to be the exception.
Material selection is another reason homeowners stick with us. We stock and source from eight major brands: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. The right material depends on your attic’s condition, not what’s already on the truck. In a 1930s King William bungalow, dense-packed cellulose may be the move. In a 2005 Alamo Ranch tract home, blown fiberglass to R-49 might be the answer. We match it to the house.
Attic Insulation Removal in San Antonio
Attic insulation removal in San Antonio is often the first step when old blown-in material has settled, compacted, or been contaminated by rodents or roof leaks. Many 1990s and early 2000s homes in the Alamo Ranch and far west areas were built to code minimums that don’t hold up after 15 to 20 years of Hill Country heat. We remove the degraded fill, inspect the attic floor, and set you up for fresh material at the correct depth. Removal typically runs $1 to $2.50 per square foot depending on access and material type. A 1,500-square-foot attic usually lands between $1,500 and $3,800 for full removal and prep.
Why San Antonio Homes Need It
Settled insulation drops in R-value fast. The R-value is the number that measures how well insulation slows heat from moving through your ceiling. Blown fiberglass that started at R-30 can settle below R-19 within 15 years, leaving bare spots directly over bedrooms. We see this pattern constantly in production-built homes from the 1990s. The only real fix is removal and replacement, not just piling more on top.
What We Do After Removal
Once the old material is out, we air seal the attic floor at top plates, can lights, and plumbing penetrations. Builders in far northwest San Antonio often skipped this step entirely. Sealing those gaps stops the stack effect that pulls 140°F attic air into your living space. Then we blow fresh insulation to the R-value your ceiling needs.
Blown In Insulation in San Antonio
Blown in insulation in San Antonio is the most common retrofit we install because it fills irregular cavities and covers existing material evenly. For most homes, blown fiberglass or cellulose goes in fast and reaches the R-value needed to cut cooling loads. Expect to pay $1,200 to $2,800 for a typical 1,200 to 2,000 square foot attic at R-38 to R-49, including air sealing at key penetrations. Dense-packed cellulose wall retrofits run higher because they require drilling and patching access holes.
Blown Fiberglass vs. Cellulose
Fiberglass from Owens Corning holds its loft and settles less over time. Cellulose from GreenFiber packs tighter and blocks air movement better, which helps in older homes with leaky wall cavities. In an August attic that’s already at 140°F, the difference between R-19 and R-49 shows up directly on your CPS Energy bill.
Top-Ups and R-Value Boosts
If your existing insulation is still clean but shallow, a top-up is the cheapest route. Adding 6 to 10 inches of blown material over settled fill can bring an R-19 attic up to R-38 for $600 to $1,400 in a standard San Antonio ranch. We check moisture and existing depth first. If there’s rat debris or water damage, removal becomes the smarter call.
Trusted Brands We Service in San Antonio
We work with materials from Owens Corning, GreenFiber, Icynene, and Demilec, among others, and we keep common stock ready for fast turnaround across San Antonio. That means when a homeowner in Universal City or Converse calls about an attic that’s cooking, we’re not waiting on a distributor. Owens Corning fiberglass is our standard for blown attic work. GreenFiber cellulose handles dense-pack wall retrofits in older pier-and-beam homes. For homeowners who want air sealing plus insulation in one pass, Icynene spray foam is a strong open-cell option. Your quote names the material and the R-value target in writing.
Common Attic Insulation Problems We See in San Antonio Homes
- Settled blown-in insulation in 1990s Alamo Ranch homes. Fifteen years in, R-30 becomes R-19 or worse and bare spots show up over bedrooms. The fix is removal, air sealing, and fresh blow to R-49.
- Blocked attic access in older pier-and-beam bungalows. Homes in Beacon Hill and Jefferson often have scuttles covered by plywood or walled off by remodeled closets. We cut new access from hallway ceilings and insulate around the opening.
- Missing air sealing at top plates and can lights. Builders in far northwest San Antonio regularly skipped this detail. Heat leaks through every electrical penetration even when fiberglass depth looks adequate.
- Original 1920s-1940s homes with no wall insulation. King William and Monte Vista bungalows often have only a thin layer of old attic fill and single-pane windows. Dense-packed cellulose wall retrofits plus attic upgrades make a massive difference in August.

FAQs About Attic Insulation in San Antonio
Attics in San Antonio routinely exceed 140°F during summer afternoons, and some older, poorly vented attics climb past 150°F. That’s hot enough to radiate heat through the ceiling into bedrooms and hallways, driving your air conditioner to run almost constantly. Proper insulation and air sealing stop that radiant transfer. Call (254) 279-0971 and we’ll measure what’s actually in your attic.
Yes. King William and Monte Vista homes from the 1920s through 1940s often have no wall insulation at all and only a thin, compacted layer in the attic. Those houses usually need dense-packed cellulose wall retrofits plus a full attic re-blow. Newer Alamo Ranch homes more often need removal of settled 1990s fill and air sealing at top plates.
Insulation itself doesn’t dehumidify, but air sealing plus proper insulation reduces the stack effect that pulls hot, humid outside air through attic penetrations. That cuts the moisture load on your AC and keeps dust from being drawn through can lights and top plate gaps. In San Antonio’s semi-arid climate, it’s one of the most practical upgrades you can make.
Yes. We work in tight attic spaces regularly, including townhomes with small scuttles and shared firewalls. Blown-in insulation fits through narrow access and covers the entire attic floor, including edges near shared walls. If the access is too small to work through safely, we can cut a new access panel and seal it when we’re done. Call (254) 279-0971 and we’ll take a look.
Blown-in insulation adds material over your existing attic floor. Removal takes old, settled, or contaminated material out first, then we air seal and blow fresh insulation to the correct R-value. In many 1990s San Antonio homes, removal is necessary because the existing fill has compacted below R-19 and can’t be topped up effectively. We’ll tell you straight which route makes sense after seeing your attic. Estimates are free.
