GreenFiber Wall Insulation in Seguin: What to Know First
We provide independent GreenFiber wall insulation service in Seguin, typically completing drill-and-fill and injection jobs within one to two days of your written estimate. Most GreenFiber wall insulation projects in Seguin homes run between $2,400 and $4,800 depending on wall cavity depth, square footage, and whether existing material must be removed first. We give you a written price before any work starts, and every job closes with a Documented Photo Record plus before-and-after blower-door numbers where applicable. This page is for Seguin homeowners who already have GreenFiber insulation in their walls and need it repaired, topped off, or replaced, or for those considering GreenFiber for a retrofit in an older home. Call (830) 549-6646 for a free estimate.
How GreenFiber Products Fail - and How We Fix Them
- GreenFiber Sanctuary settled below top plate in balloon-framed walls. Sanctuary’s higher recycled-content blend absorbs more atmospheric moisture than other cellulose lines, and in Seguin’s spring humidity swings it can compress 15-20 percent in the first three years. We remove the settled pack, seal the top plate with closed-cell foam at all penetrations, then re-blow to 3.5 pounds per cubic foot so it stays put.
- GreenFiber All Borate-treated wall cavities showing thermal drift near exterior corners. The all-borate fire retardant is effective but can leach toward the exterior sheathing in walls with poor vapor management, creating cold spots we pick up with infrared during our initial scan. We spot-remove the shifted material, install a smart vapor retarder where missing, and re-dense-pack the cavity.
- GreenFiber Low Dust formula refusing to bond in narrow 2×4 stud bays. The low-dust additive reduces installer exposure but changes fiber cohesion, and in the tight 14.5-inch cavities common in Seguin’s 1960s-1980s ranch stock it can bridge instead of filling. We switch to a wet-spray application or use our own modified hose pressure profile to achieve full contact without voids.
- GreenFiber stabilized cellulose slumping above headers and lintels. The acrylic binder breaks down faster when subjected to the radiant heat gain off Seguin’s south-facing brick veneer in summer. We install rigid mineral wool baffles at these thermal hotspots before re-insulating, which prevents the cycle from repeating.
- GreenFiber product contaminated by prior rodent activity in wall cavities. Cellulose holds urine scent that draws reinfestation; we see this most in GreenFiber jobs because the borate treatment does not deter nesting. We remove all contaminated material, HEPA-vacuum the bays, seal entry paths with copper mesh and foam, then install fresh product.
Our GreenFiber Wall Insulation Process
- 1
Site survey and blower-door baseline. We run a pressurization test to establish your home’s starting ACH50, then use infrared and borescope inspection to map cavity conditions without unnecessary drywall cuts.
- 2
Written price and scope delivered. You get a flat price, material specification, and timeline before anyone schedules work. No verbal estimates, no scope changes mid-job.
- 3
Air sealing before insulation. We seal top plates, electrical penetrations, and any gaps at the rim joist with foam or caulk appropriate to the assembly. Insulation goes in only after the pressure boundary is continuous.
- 4
GreenFiber installation with density verification. We blow to manufacturer weight per cubic foot or wet-spray to the specified depth, checking with core samples at multiple wall locations. OEM GreenFiber is used unless you approve a quality aftermarket alternative in writing.
- 5
Post-work blower-door test and documentation. We pressurize again, compare to the baseline, and hand you the printed report with both ACH50 figures. The report goes home with you - the numbers do the talking.
- 6
Cleanup and 365-Day Done Right Promise activation. Your Documented Photo Record is uploaded, your written warranty is in hand, and our promise is in effect.

Why Seguin Homeowners Call Topside Attic Insulation Seguin for GreenFiber Work
We’ve sealed and insulated over 9,000 homes since 2016, and a growing share of our Seguin work involves GreenFiber retrofits in the neighborhoods near Guadalupe Regional Medical Center, where 1950s-1970s framing makes air sealing non-negotiable. Wes Okafor runs the blower-door test himself on applicable jobs and hands you the pre- and post-installation report with actual ACH50 numbers. Our 365-Day Done Right Promise means if the density drops or a void opens, we make it right. We’re also familiar with Reflectix and other multi-layer systems if your wall assembly needs a hybrid approach. Calls are answered by a live person 24/7, and our technicians are background-checked and uniformed.
FAQs
No. GreenFiber’s product warranty covers manufacturing defects regardless of who installs it, provided the product was stored and applied to manufacturer specifications. We document density, moisture content, and installation conditions so any legitimate claim has backing. Call (830) 549-6646 if you need help interpreting your existing warranty language.
Yes, if the original product is identifiable. GreenFiber’s stabilized and low-dust lines achieve slightly different settled densities, so we core-sample the existing material to match the thermal performance rather than guessing by bag count. Call (830) 549-6646 for an exact quote - estimates are free.
Spot repair is cheaper if settlement is localized and the remaining material is dry and uncontaminated. Full removal and replacement is the better value when more than 30 percent of the wall has shifted, compressed, or been disturbed by moisture or pests. We tell you which category you’re in after the borescope inspection, not before.
Most GreenFiber wall insulation jobs in Seguin are scheduled within three to five business days of your written estimate approval. Emergency situations, such as insulation saturated by plumbing leaks, can sometimes be addressed next-day. Call (830) 549-6646 for current availability.
We source GreenFiber through our regular supply chain along with Owens Corning, Johns Manville, Knauf, Rockwool, and other manufacturers. You do not need to order material yourself. We specify the exact product line in your written scope so you know what you’re getting.
