Owens Corning Blown-In Insulation Nationwide

Owens Corning Blown-In Insulation in Seguin: What to Know First

We provide independent Owens Corning blown-in insulation service in Seguin and the surrounding Hill Country edge, with most attic jobs completed in a single day and pricing put in writing before any work starts. A typical blown-in top-up or full replacement runs between $1,800 and $4,200 depending on attic square footage, existing insulation condition, and whether air sealing is needed first. We do not quote over voicemail; a technician visits, measures, and delivers a written scope with a flat price.

This page is for homeowners in Seguin who already have Owens Corning insulation in their attic or walls and need to add to it, replace it, or figure out why it is not performing. If you are in a neighborhood near Guadalupe Regional Medical Center, in the older construction around Kingsbury, or in newer builds toward McQueeney, the framing details and ventilation setups differ, and we account for that in the scope. Call (830) 549-6646 to schedule a free estimate with written pricing.

How Owens Corning Products Fail - and How We Fix Them

• Owens Corning AttiCat PINK Fiberglass Blown-In settling below labeled R-value. The AttiCat system uses loose-fill fiberglass that can settle 10-15 percent in Seguin’s combination of high summer attic temperatures and seasonal humidity swings, especially in homes built between 2015 and 2020 where truss spacing is wider. We measure existing depth with a ruled probe, calculate settled density against the original bag count, and blow to the corrected depth for your target R-value, not the minimum.
• Owens Corning ProCat Loose Fill bridging over top plates and leaving thermal bypasses. ProCat installs fast, but in Seguins older homes with irregular ceiling joists or modified framing, it can bridge across bays instead of filling to the heel. We pull back existing ProCat, seal top plates and wire penetrations with fire-rated caulk and rigid foam, then redistribute or add new material so the thermal boundary is continuous.
• Owens Corning EcoTouch PINK Fiberglass degraded by prior roof leaks or rodent activity. EcoTouch is treated with a mold-resistant binder, but it is not waterproof. In Seguins flash-flood-prone areas near the Guadalupe River watershed, we find EcoTouch compressed and stained in valleys where slow leaks went unnoticed. We remove the damaged section, photograph the deck condition for your record, and replace with new blown-in after verifying the leak source is resolved.
• Owens Corning blown-in installed over unsealed can lights and chimney chases. This is not a product defect but an installation failure we see repeatedly on Seguin homes where insulation was added without prior air sealing. Conditioned air pumps straight into the attic through IC-rated but unsealed housings. We never blow new Owens Corning material until we have sealed these penetrations; otherwise we are burying the problem under more insulation.
• Owens Corning AttiCat machine-set density too low for wall-spray applications. When AttiCat is used for dense-pack sidewalls in Seguins 1960s and 1970s ranch homes, an inexperienced operator can set the blower too fast and leave the cavity underfilled. We verify dense-pack density by feel and by the resistance on the hose; a proper dense-pack should require noticeable pressure to advance. If we are adding to existing Owens Corning wall insulation, we drill and probe first to check what is already there.

Our Owens Corning Blown-In Insulation Process

1. 1
   Schedule and arrival. You call (830) 549-6646, a live person answers, and we book a window. Wes Okafor or a named technician arrives on time and texts when en route.
2. 2
   Attic inspection and blower-door test. We run a blower-door test, a pressurization diagnostic that measures how much conditioned air your house loses per hour, to establish a baseline. We photograph existing Owens Corning insulation condition, measure depths, and mark air leaks with flags.
3. 3
   Written scope and flat price. Before any work starts, you receive a written price with the exact material specification, R-value target, air-sealing detail, and warranty terms. This is Haven Standard Clause 1; no work begins without it.
4. 4
   Air sealing first, then insulation. We seal top plates, can lights, plumbing and electrical penetrations, and chimney chases with appropriate fire-rated materials. Only after the pressure boundary is intact do we run the blower for new Owens Corning blown-in.
5. 5
   Installation and post-test. We install to the specified depth and density, then run a second blower-door test. The report goes home with you - the numbers do the talking. You get before-and-after ACH50 readings, depth verification photos, and a Documented Photo Record of the completed work.
6. 6
   Cleanup and 365-Day Done Right Promise. We vacuum, replace attic hatch insulation if removed, and leave the written warranty. If anything is not right, we make it right within one year.

What Owens Corning Blown-In Insulation Costs in Seguin

Most Owens Corning blown-in insulation jobs in Seguin homes run between $1,800 and $4,200. The price moves based on four factors we measure during the free estimate:

• Attic square footage: A 1,200-square-foot attic with standard pitch runs lower than a 2,500-square-foot complex roof with multiple dormers.
• Existing insulation condition: Top-ups over sound existing material cost less than full removal and replacement of water-damaged or rodent-contaminated Owens Corning product.
• Air sealing extent: Sealing ten can lights, multiple top plates, and a chimney chase adds labor and material but is required before we blow anything new.
• Access difficulty: Steep-pitch roofs, limited attic hatches, or cramped truss bays in older Seguin homes near downtown add time.

We also source from Johns Manville, Knauf, Rockwool, CertainTeed, and GreenFiber if your job calls for a different material performance profile, and we will explain why if we recommend a switch. Bring us any competing written estimate for a Free Second Opinion; we will read it with you line by line. Call (830) 549-6646 for your written price.
