Why Topside Attic Insulation San Marcos Is Bastrop’s Preferred Blown-In Insulation Company
We’ve worked in Bastrop long enough to know the difference between a home built before the 2011 Complex Fire and one thrown up during the 2012-2016 rebuild rush. That matters. The post-fire rebuild homes in Lost Pines and the surrounding subdivisions east of town were insulated to builder-minimum standards under serious time pressure. A decade later, that blown fiberglass has settled, compressed, and in many cases failed to perform against the summers and freeze events Bastrop actually experiences.
Our crews know to check soffit vents for pine needle packing before we ever touch the insulation. It’s a failure mode we see almost exclusively in Bastrop’s loblolly canopy neighborhoods. Installers from outside the area miss it routinely.
We arrive with a written price before any work starts - Haven Standard Clause 1 - and we leave with a Documented Photo Record and, on applicable jobs, before-and-after blower-door numbers that show exactly what changed. Our 365-Day Done Right Promise covers all completed work. Calls are answered by a live person, not a voicemail loop, and you’ll get a text when your technician is on the way.
Our Blown-In Insulation Services in Bastrop
Blown-In Fiberglass
This is the workhorse for most Bastrop attics, especially the post-2011 rebuild homes that started with substandard blown fiberglass and now need a proper job. We source from Owens Corning, Johns Manville, and Knauf - no proprietary lock-in that limits your options. In Bastrop’s humid loblolly microclimate, we pay particular attention to attic ventilation before blowing; trapped moisture degrades fiberglass faster here than in drier Central Texas markets like Elgin. A typical full-attic blown fiberglass job in Bastrop runs $2,200-$3,800.
Blown-In Cellulose
Made from recycled paper treated with borate fire retardant, cellulose performs well in Bastrop’s older homes with irregular joist spacing or multiple penetrations to seal. It packs tighter around ducts and wiring than fiberglass, which matters in the pre-1980s wood-frame homes near downtown and along the Colorado River. We don’t blow cellulose over an unsealed attic floor - air sealing of top plates, can lights, and penetrations comes first, every time. Cellulose jobs in Bastrop typically fall between $2,000-$3,600.
Blown-In Top-Up
Not every Bastrop attic needs a full strip-and-replace. If your existing insulation is in reasonable shape but has settled below its labeled R-value - common in those 2012-2016 post-fire builds where code-minimum batts were the starting point - a top-up can bring you to R-38 or R-49 without the cost of full removal. We’ll test what you’ve got, photograph the condition, and give you a written price for the top-up versus full replacement so you can decide with actual numbers. Top-ups in Bastrop generally run $1,800-$2,800.
Dense-Pack Wall Insulation
The pre-1980s homes in Bastrop’s older neighborhoods and along the river often have empty stud cavities - no insulation at all in the walls. Dense-pack cellulose or fiberglass, blown in at pressure through access holes, fills those cavities without tearing off siding or drywall. It’s slower work than attic blowing, but for homes that have gone forty-plus years with uninsulated walls, the comfort difference is immediate. Dense-pack wall jobs in Bastrop range from $3,200-$5,500 depending on wall area and access.

Before
AfterTrusted Brands We Service in Bastrop
We stock and install materials from Rockwool, CertainTeed, and Icynene for Bastrop jobs, sourced through regional distributors with next-day availability for most products. No proprietary product lock-in - we specify what performs for your specific assembly and budget, not what moves our inventory. For post-fire rebuild homes needing moisture-resistant solutions, we often specify CertainTeed fiberglass with enhanced water repellency or Rockwool mineral wool in problem attics where condensation has been an issue. Demilec open-cell foam is available for hybrid jobs where spray foam sealing plus blown-in topping makes sense.
Common Blown-In Insulation Problems We See in Bastrop Homes
- Settled builder-grade fiberglass in Lost Pines rebuild homes. The 2012-2016 post-fire construction wave used blown fiberglass and standard batts installed to then-minimum code. A decade of thermal cycling and compression has dropped many of these attics to under R-19. We measure what you’ve actually got before recommending any work.
- Pine needle blockage of soffit vents. The loblolly canopy in Lost Pines and east-of-town neighborhoods sheds needles that pack tight against soffit vents, cutting off the intake air that attic ventilation systems depend on. Without that cross-flow, blown insulation traps moisture and loses R-value. We clear and screen vents as part of our prep.
- Attic condensation from Bastrop’s humid microclimate. Bastrop’s isolated pine forest runs higher ambient humidity than surrounding open country. That humidity migrates into attics through bypasses and unsealed penetrations, condensing on cool roof sheathing in winter and degrading insulation year-round. Air sealing comes first, always.
- Freeze-event damage from February 2021 and after. The extended freeze stressed insulation systems across Bastrop. Homes with marginal attic insulation saw ice dam formation and interior moisture damage. Post-event, we’re seeing compressed or water-stained insulation that reads fine on visual inspection but performs poorly under thermal imaging.

FAQs - Blown-In Insulation in Bastrop
Those homes were built between 2012 and 2016 under serious time pressure, with insulation installed to then-minimum code standards using blown fiberglass or standard batts that have since settled and compressed. A decade of Bastrop’s thermal cycling - 100°F+ summers and freeze events like February 2021 - has degraded performance further, dropping many attics to under R-19 despite original R-30 labels. We measure actual in-place R-value before recommending any work. Call (737) 337-8049 for a free assessment.
Pine needles pack against soffit vents and cut off the intake airflow that attic ventilation depends on, which causes blown insulation to trap moisture and lose effective R-value. It’s a failure mode we find regularly in Bastrop’s pine-canopy neighborhoods and almost never see diagnosed by installers based in other towns. We clear and screen soffit vents before any insulation work begins. Call (737) 337-8049 to schedule an inspection.
Yes. Bastrop’s isolated loblolly pine forest creates a localized microclimate with higher ambient humidity than the surrounding open Central Texas landscape, so attic condensation and moisture degradation of blown insulation appear more frequently here despite similar air temperatures. That humidity difference means we prioritize air sealing and ventilation assessment more aggressively in Bastrop than in comparable nearby markets. Call (737) 337-8049 and we’ll test your attic’s moisture conditions.
Properly installed blown-in insulation to current code levels - R-38 minimum, R-49 preferred - performs at both extremes by slowing heat flow in both directions. The problem in Bastrop isn’t the insulation type; it’s the degraded or insufficient insulation we find in post-fire rebuild homes and older uninsulated structures. We specify materials and depths for your actual conditions, not a generic standard. Call (737) 337-8049 for a written scope and price.
Blown cellulose handles irregular joist spacing and fills around existing wiring and plumbing better than fiberglass in these older wood-frame and pier-and-beam structures. Dense-pack wall insulation fills empty stud cavities without demolition. We air-seal the attic floor and top plates first - critical in homes that have had decades of air leakage - then blow to the appropriate depth. Call (737) 337-8049 for an estimate tailored to your home’s construction.
